- What is an Active Session?

- Viewing the Active Sessions Report

See Also:
"Undertanding Session State Management" in Oracle Application Express Application Builder User's Guide

1.2.4.1 What is an Active Session?

Whenever an application is run, the Application Express engine maintains a record in a database table in the Oracle Application Express schema. This table records a numeric identifier (or session ID), the authenticated (or public) user identifier, the creation date, and other information. The session is the key record that enables session state, or persistence, across page requests. By viewing the Active Sessions report, a developer or administrator can see who has been using applications in a workspace.

If the Instance administrator does not enable login controls across an entire instance, then each Workspace administrator can configure the following controls on a workspace-by-workspace basis:

- End-user account expiration and locking

- A maximum number of failed login attempts for end-user accounts

- The password lifetime (or number of days an end-user account password can be used before it expires for end-user accounts

Tip:
This feature applies only to accounts created using the Application Express user creation and management. Application Accounts Authentication provides additional authentication security for applications. See "Managing Users in a Workspace."

- Removing Session State After Reviewing Session Details

- Viewing Session State for the Current Session

- Purging Sessions by Age

- Purging Session State for the Current Session

See Also:
"Managing Session State" in Oracle Application Express Application Builder User's Guide and "Managing Session State for an Instance"

1.9.1 About Session State

A session is a logical construct that establishes persistence (or stateful behavior) across page views. Each session is assigned a unique ID, which the Application Express engine uses to store and retrieve an application's working set of data (or session state) before and after each page view. Sessions persist in the database until purged.

See Also:
"What Is a Session?" in Oracle Application Express Application Builder User's Guide

1.9.2 Removing Session State After Reviewing Session Details

You can determine whether to remove existing sessions by first reviewing session details. From the Session Details page, you can remove the session record or session state.

To view session details and remove session state:

1. Navigate to the Workspace Administration page. See "Accessing the Workspace Administration Page."
The Workspace Administration home page appears.

2. On the Administration page, click Manage Service.

3. Under Manage Meta Data, click Session State.

4. Click Recent Sessions.
You can customize the appearance of the page using the Search bar at the top of the page

5. To view session details, select the session ID.
The Session Details page appears.

6. Click one of the following buttons:

- Remove State clears the session data from the session state tables (including collections data) but does not remove the session record. Removing a session is a good approach for developers during debugging.
This is the equivalent of clearing session state for the current session using the Clear Cache argument value SESSION in the f?p URL. This option might also be used by developers during debugging.

- Remove Session removes the record of the session from the SESSIONS table along with the session state (including collections data) associated with the session.
Any user using a session that has removed is no longer able to use the session and is prompted to re-authenticate upon their next page request (in most situations). This option can be used by administrators who must ensure a specific user can no longer access an Oracle Application Express application.

The Checksum Hash Function attribute enables you to react to recent developments and switch between algorithms based on new research. Use the Checksum Hash Function attribute to select a hash function that Oracle Application Express uses to generate one way hash strings for checksums. This attribute is also the default value for the Security Bookmark Hash Function attribute in new applications. Applications use the Bookmark Hash Function when defining bookmark URLs.

Tip:
Changing the Checksum Hash Function does not change the Bookmark Hash Function currently defined for existing applications because this would invalidate all existing bookmarks saved by end users.Oracle strongly recommends going into existing applications, expiring existing bookmarks, and then updating the Bookmark Hash Function to the same value defined for Checksum Hash Function.

To select a checksum hash function:

1. Sign in to Oracle Application Express Administration Services. See "Accessing Oracle Application Express Administration Services."

2. Click Manage Instance.

3. Under Instance Settings, click Security.

4. Locate the Security section.

5. From Checksum Hash Function, select a a hash function that Application Express uses to generate one way hash strings for checksums.
The SHA-2 algorithms are only supported on Oracle Database 12c or later. Most Secure automatically selects the most secure algorithm available. Therefore, Oracle recommends this setting. On Oracle Database 12c or later, this evaluates to SHA-2, 512 bit and on Oracle Database 11g, SHA-1 is the most secure algorithm. Since the MD5 algorithm is deprecated, Oracle does not recommend this setting.

6. Click Apply Changes.

2.5.2.1.9 Configuring Rejoin Sessions for an Instance

By configuring the Rejoin Sessions attribute, Instance administrators can control if Oracle Application Express supports URLs that contain session IDs. When rejoin sessions is enabled, Oracle Application Express attempts to use the session cookie to join an existing session, when a URL does not contain a session ID.

Warning:
For security reasons, Oracles recommends that administrators disable support for session joining unless they implement workspace isolation by configuring the Allow Hostname attributes. See "Isolating a Workspace to Prevent Browser Attacks" and "Isolating All Workspaces in an Instance."

Note:
Enabling rejoin sessions may expose your application to possible security breaches, as it can enable attackers to take over existing end user sessions. To learn more, see "About Rejoin Sessions" in Oracle Application Express Application Builder User's Guide

To configure Rejoin Sessions:

1. Sign in to Oracle Application Express Administration Services. See "Configuring Rejoin Sessions for an Instance."

2. Click Manage Instance.

3. Under Instance Settings, click Security.

4. Locate the Security section.

5. From Rejoin Sessions, select an option:

- Disabled - If the URL does not contain a session ID, Oracle Application Express creates a new session.

- Enabled for Public Sessions - If the URL goes to a public page and does not contain a session ID Oracle Application Express attempts to use the existing session cookie established for that application. Oracle Application Express only joins using the cookie when the session is not yet authenticated.

- Enabled for All Sessions - If the URL does not contain a session ID, Oracle Application Express attempts to use the existing session cookie established for that application, providing one of the following conditions are met:

- Session State Protection is enabled for the application and the URL includes a valid checksum. For public bookmarks, the most restrictive item level protection must be either Unrestricted or Checksum Required - Application Level.

- The URL does not contain payload (a request parameter, clear cache or data value pairs). This setting requires that Embed In Frames is set to Allow from same origin or to Deny for the application.

Enabled for Public Sessions requires that Embed in Frames is set to Allow from same origin or Deny. This is not tied to a condition about the URL payload, but also applies to session state protected URLs.

6. Click Apply Changes.

2.5.2.1.10 Configuring Unhandled Errors

Use this attribute to control how Oracle Application Express displays the results of unhandled errors. When Oracle Application Express encounters an unhandled error during processing, an error page displays to the end user of the application. From a security standpoint, it is often better to not display these messages and error codes to the end user and simply return a HTTP 400 (Bad Request) error code to the client browser.

To configure Unhandled Errors:

1. Sign in to Oracle Application Express Administration Services. See "Accessing Oracle Application Express Administration Services."

2. Click Manage Instance.

3. Under Instance Settings, click Security.

4. Locate the Security section.

5. From Unhandled Errors, select an option:

- Show Error Page - This is the default behavior. For any error or exception which is not handled by the error processing of an application, an error page displays to the end user with the specific error and the error code.

- Return HTTP 400 - Returns an HTTP 400 status to the end user's client browser when the Application Express engine encounters an unhandled error.

6. Click Apply Changes.

2.5.2.2 Configuring HTTP Protocol Attributes

2.5.2.6 Isolating All Workspaces in an Instance

This section describes how Instance administrators can isolate a workspace and prevent browser attacks.

- About Isolating a Workspace to Prevent Browser Attacks

- Configuring Workspace Isolation Attributes

2.5.2.6.1 About Isolating Workspaces to Prevent Browser Attacks

Isolating workspaces is an effective approach to preventing browser attacks. The only way to truly isolate a workspace is to enforce different domains in the URL by configuring the Allow Hostnames attribute. When the URLs of the attacker and the victim have different domains and hostnames, the browser's same-origin policy prevents attacks.

See Also:
"Isolating a Workspace to Prevent Browser Attacks" and "About Isolating Workspaces" in Oracle Application Express Application Builder User's Guide

2.5.2.6.2 Configuring Instance-Level Workspace Isolation Attributes

To configure instance-level Workspace Isolation attributes:

1. Access the Edit Workspace Information page for the workspace:

1. Sign in to Oracle Application Express Administration Services. See "Accessing Oracle Application Express Administration Services."

2. Click Manage Instance.

3. Under Instance Settings, click Security.

2. Locate the Workspace Isolation section.

3. Edit the appropriate attributes as described in Table 2-2.

Tip:
To learn more about an attribute, see field-level Help.

Table 2-2 Workspace Isolation Attributes

Attribute

Description

Allow Hostnames

Enter a comma separated list of hostnames that can be used to access this instance. This attribute can be used to specify which DNS aliases of the web server can be used with applications. You can configure specific values that override this one at workspace level. If you enter one or more hostnames, the incoming HTTP request URL's hostname part must match one of the listed hostnames.

Resource Consumer Group

Specify the Database Resource Manager consumer group to be used for all page events on the instance. You can configure specific values that override this one at the workspace-level. At the beginning of every request, the Application Express engine switches the current consumer group of the current database session to the consumer group that is defined at workspace or instance level. This applies to both executing applications and any of the applications used within the Application Express development environment.

The privilege to switch to this consumer group must be granted to either PUBLIC or the Application Express schema. This privilege is typically granted using the procedure DBMS_RESOURCE_MANAGER_PRIVS.GRANT_SWITCH_CONSUMER_GROUP.

Maximum Concurrent Workspace Requests

Enter the maximum number of concurrent page events that Oracle Application Express supports for all applications. You can configure a specific value at the workspace-level. Instead of processing a page event, Oracle Application Express shows an error message when the limit is already reached.

Oracle Application Express keeps track of workspace requests by querying the CLIENT_INFO column of GV$SESSION. This tracking will not work if developers overwrite CLIENT_INFO, for example, with a call to DBMS_APPLICATION_INFO.SET_CLIENT_INFO.

Maximum Concurrent Session Requests

Enter the maximum number of concurrent page events that Oracle Application Express supports for each session for applications in this instance. You can configure a specific value at the workspace-level. Instead of processing a new page event, Oracle Application Express shows an error message when the limit is already reached. Alternatively, you can use the Concurrent Session Requests Kill Timeout attribute to kill an active database session, to process the new page event.

Oracle Application Express keeps track of session requests by querying the CLIENT_IDENTIFIER column of GV$SESSION. This tracking will not work if developers overwrite CLIENT_IDENTIFIER, for example, with a call to DBMS_SESSION.SET_IDENTIFIER.

Concurrent Session Requests Kill Timeout

If a new page event comes in that is outside the limits of Maximum Concurrent Session Requests, Oracle Application Express can execute alter system kill session on the oldest active database session which processes another page event for this Application Express session. The Concurrent Session Requests Kill Timeout attribute specifies the number of seconds a database process has to be active, before it can be killed. If you leave this attribute empty, Application Express will not kill any database sessions.

Warning: Killing sessions can cause problems with the application server's database session pool.

Maximum Size of Files in Workspace

Enter the total size (in bytes) of all files that can be uploaded to a workspace. You can configure a specific value at the workspace-level.

4. Click Apply Changes.

2.5.2.7 Defining Excluded Domains for Regions and Web Services

An Instance administrator can define a list of restricted domains for regions of type URL and Web services. If a Web service or region of type URL contains an excluded domain, an error displays informing the user that it is restricted.

To define a list of excluded domain from regions of type URL and Web services:

1. Sign in to Oracle Application Express Administration Services. See "Accessing Oracle Application Express Administration Services."

2. Click Manage Instance.

3. Under Instance Settings, click Security.

2.5.2.8.1 About Authentication Controls

Administrators can configure authentication controls for an entire instance or for each individual workspace. For example, if an instance administrator configures authentication controls in Oracle Application Express Administration Services that configuration applies to all Application Express accounts in all workspaces across an entire development instance.

If the instance administrator does not enable authentication controls across an entire instance, then each Workspace administrator can enable the following controls on a workspace-by-workspace basis:

- User account expiration and locking

- A maximum number of failed login attempts for user accounts

- Account password lifetime (or number of days an end-user account password can be used before it expires for end-user accounts)

Tip:
This feature applies only to accounts created using the Application Express user creation and management. It provides additional authentication security for applications. See "Managing Users in a Workspace."

^[[:alnum:]._%-]+@[[:alnum:].-]+\.[[:alpha:]]{2,4}$

2. Require User Account Expiration and Locking - Select Yes to enable Application Express user account expiration and locking features across all workspaces in an instance. This selection prevents the same feature from being disabled at the workspace-level.
Select No to relinquish control to each Workspace administrator.

3. Maximum Login Failures Allowed - Enter a integer for the maximum number of consecutive unsuccessful authentication attempts allowed before a developer or administrator account is locked. If you do not specify a value in this field, the default value is 4.
This setting applies to administrator and developer accounts. It does not apply to end user accounts.

The value you enter is used as the default for the workspace-level Maximum Login Failures Allowed preference if the Workspace administrator does not specify a value. That preference is used for end-user accounts within the respective workspace.

4. Account Password Lifetime (days) - Enter a number for the maximum number of days a developer or administrator account password may be used before the account expires. If you do not specify a value in this field, a default value is 45 days.
This setting applies to accounts used to access the Application Express administration and development environment only. It does not apply to end user accounts.

The value you enter is used as the default workspace-level End User Account Lifetime preference, if the Workspace administrator specifies no value. That preference is used for end-user accounts within the respective workspace.

2.5.2.10 Restricting Access to Oracle Application Express by Database Access Descriptor (DAD)

This section describes how to restrict access to Oracle Application Express by Database Access Descriptor (DAD).

Tip:
The PL/SQL Request Validation Function directive is only available in Oracle Application Server 10g and Oracle HTTP Server 11g or later, and the embedded PL/SQL gateway in Oracle Database 11g or later. This directive is not available in Oracle HTTP Server Release 9.0.3.

- About Enforcing Access Restrictions Per DAD

- About the wwv_flow_epg_include_local Function

- Specifying Allowed Named Procedures

- Altering the Product Schema

2.5.2.10.1 About Enforcing Access Restrictions Per DAD

mod_plsql and the embedded PL/SQL gateway support a directive which enables you to name a PL/SQL function which is called for each HTTP request. You can use this functionality to restrict the procedures that can be called through the embedded PL/SQL gateway or mod_plsql. The function returns TRUE if the named procedure in the current request is allowed and FALSE if it is not allowed. You can also use this function to enforce access restrictions for Oracle Application Express on a per-Database Access Descriptor (DAD) basis.

During installation, the installer also creates a PL/SQL function in the Oracle Application Express product schema (APEX_050000). To restrict access, you can change and recompile this function. The source code for this function is not wrapped and can be found in the Oracle Application Express product core directory in the file named wwv_flow_epg_include_local.sql.

Oracle Application Express ships with a request validation function named wwv_flow_epg_include_modules.authorize. This function specifies access restrictions appropriate for the standard DAD configured for Oracle Application Express.

The wwv_flow_epg_include_mod_local function is called by Oracle Application Express's request validation function which itself is called by the embedded PL/SQL gateway or mod_plsql. The Oracle Application Express function first evaluates the request and based on the procedure name, approves it, rejects it, or passes it to the local function, wwv_flow_epg_include_mod_local, which can evaluate the request using its own rules.

When you create new DADs for use with Oracle Application Express, the request validation function directive should be specified. Specifically, the function wwv_flow_epg_include_modules.authorize should be named in the directive PlsqlRequestValidationFunction in the Database Access Descriptor entry in dads.conf.

If you have no additional restrictions beyond those implemented in the wwv_flow_epg_include_modules.authorize function, there is no need to take any action with respect to the source code for the wwv_flow_epg_include_mod_local function.

See Also:
Oracle Application Express Installation Guide

2.5.2.10.2 About the wwv_flow_epg_include_local Function

You can change and recompile the wwv_flow_epg_include_local function to restrict access. The source code for the wwv_flow_epg_include_local function is not wrapped and can be found in the Oracle Application Express product core directory in the file named wwv_flow_epg_include_local.sql. The source code is as follows:

CREATE OR REPLACE FUNCTION
wwv_flow_epg_include_mod_local(
PROCEDURE_NAME IN VARCHAR2)
RETURN BOOLEAN
IS
BEGIN
RETURN FALSE; -- remove this statement when
you add procedure names to the "IN" list
IF UPPER(procedure_name) IN (
'') THEN
RETURN TRUE;
ELSE
RETURN FALSE;
END IF;
END wwv_flow_epg_include_mod_local;
/

2.5.2.10.3 Specifying Allowed Named Procedures

To specify names of procedures that should be allowed, edit wwv_flow_epg_include_localas follows:

1. Remove or comment out the RETURN FALSE statement that immediately follows the BEGIN statement:

...
BEGIN
RETURN FALSE; -- remove this statement when
you add procedure names to the "IN" list
...

2. Add names to the clause representing procedure names that should be allowed to be invoked in HTTP requests. For example to allow procedures PROC1 and PROC2 the IN list you would write IN ('PROC1', 'PROC2').
After changing the source code of this function, alter the Oracle Application Express product schema (APEX_050000) and compile the function in that schema.

2.5.2.10.4 Altering the Product Schema

To alter the product schema, APEX_050000

1. Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS. For example:

- On Windows:

SYSTEM_DRIVE:\ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password

- On UNIX and Linux:

$ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password

2. Alter the product schema (APEX_050000) by entering the following command:

ALTER SESSION SET CURRENT_SCHEMA APEX_050000;

3. Compile the function wwv_flow_epg_include_local.sql.

2.5.2.11 Managing Authorized URLs

2.5.3.1 About Configuring Self Service Workspace Provisioning

The instance administrator determines the amount of automation when provisioning (or creating) a workspace. To determine how provisioning works, an Instance Administrator selects one of the following Provisioning Status options on the Instance Settings page:

- Manual - In this mode, an instance administrator creates new workspaces and notifies the Workspace administrator of the login information.

- Request - Users request workspaces directly in a self-service fashion. Users click a link on the login page to access a request form. After the workspace request has been granted, users are automatically emailed the appropriate login information.

- Request with Email Verification - In this mode, users request workspaces directly by clicking a link on the Sign In page to access a request form. Each user receives an initial email containing a verification link. When the user clicks the verification link, the request is processed. The user can then access the workspace using the Sign In page.

Note:
To enable users to request a workspace using a link on the Sign In page, you must choose the provisioning status of Request or Request with Email Verification as described in the previous section. If the provisioning status is set to Manual, no link appears on the sign in page.

See Also:
"Selecting a Provisioning Mode" "Disabling Email Provisioning," "Configuring Email," and "Managing Workspace and Change Requests"

2.5.3.2 Disabling Email Provisioning

If Encrypted Tablespaces is enabled, tablespaces provisioned with Oracle Application Express are created as encrypted tablespaces using the Oracle database feature Transparent Data Encryption (TDE). TDE encrypts sensitive data stored in data files. To prevent unauthorized decryption, TDE stores the encryption keys in a security module external to the database.

To be able to exploit this feature in Application Express, an encryption wallet must be created and with a master encryption key set. Additionally, the encryption wallet must be open before provisioning a new Application Express workspace.

To enable Encrypted Tablespaces:

1. Sign in to Oracle Application Express Administration Services. See "Accessing Oracle Application Express Administration Services."

2. Click Manage Instance.

3. Under Instance Settings, click Instance Settings.

4. Scroll down to Storage.

5. For Encrypted Tablespaces, select Yes.

2.5.3.4.1 About Enabling Network Services

If you are running Oracle Application Express with Oracle Database 11g or later, you must enable outbound mail. Starting with Oracle Database 11g Release 1 (11.1), the ability to interact with network services is disabled by default.

By default, the ability to interact with network services is disabled in Oracle Database 11g or later. Therefore, if you are running Oracle Application Express with Oracle Database 11g or later, you must use the DBMS_NETWORK_ACL_ADMIN package to grant connect privileges to any host for the APEX_050000 database user. Failing to grant these privileges results in issues with:

- Sending outbound mail in Oracle Application Express.

- Using Web services in Oracle Application Express.

- PDF/report printing.

2.5.3.6 Configuring Report Printing

This section describes how to configure report printing options for an Oracle Application Express instance.

- About Configuring Report Printing

- Configuring Report Printing in a Full Development Environment

- Configuring Report Printing Settings in a Runtime Environment

- Determining Report Printing Settings in a Runtime Environment

2.5.3.6.1 About Configuring Report Printing

Oracle Application Express provides several features so that end users can download and print reports in various formats, including PDF. To set up this functionality, different users must configure the following printing settings:

1. Site Level: Instance administrators must specify the level of functionality (Standard or Advanced) for an entire Oracle Application Express instance, as described in this section.

2. Application Level: Workspace administrators and developers can define Report Queries and Report Layouts. Report Queries and Report Layouts are stored under Shared Components and are not tied to a specific page.

3. Page/Region Level: Developers can edit the Report regions on specific pages to enable printing. This, in turn, enables end users to print regions as reports in various formats. See "Configuring Classic Report Region Print Attributes" in Oracle Application Express Application Builder User's Guide.

Tip:
If you are running Oracle Application Express with Oracle Database 11g Release 1 (11.1) or later, you must enable network services to use report printing. See "Enabling Network Services in Oracle Database 11g or Later" for your configuration scenario in Oracle Application Express Installation Guide.

2.7.1.1 About Session State

A session is a logical construct used to establish persistence (or stateful behavior) across page views. Each session is assigned a unique ID, which the Application Express engine uses to store and retrieve an application's working set of data (or session state) before and after each page view. An automatic process clears sessions older than 24 hours every eight hours. Instance administrators can also purge them manually.

See Also:
"What Is a Session?" in Oracle Application Express Application Builder User's Guide

2.8 Installing Exported Applications in a Runtime Environment

Note:
Functionality in the Administration Services application is not available in Oracle Database Cloud Service (Database Schema).

This section describes how to install exported applications into a runtime environment.

- About the Advantages of Using Runtime Environment

- Installing an Exported Application in to a Runtime Environment

2.8.1 About the Advantages of Using Runtime Environment

An Oracle Application Express runtime environment enables you to run production applications, but it does not provide a web interface for administration. A runtime environment only includes the packages necessary to run your application, making it a more hardened environment.You administer the Oracle Application Express runtime environment using SQL*Plus and the APEX_INSTANCE_ADMIN API.

See Also:
"APEX_INSTANCE_ADMIN" in Oracle Application Express API Reference.

Tip:
Websheets are not supported in an Oracle Application Express runtime environment.

2.8.2 Installing an Exported Application in to a Runtime Environment

To install an exported application into a runtime installation, you must:

1. Export the workspace from the Application Express instance where the application was developed as described in "Exporting and Importing a Workspace."

2. Use SQL*Plus to import your workspace in to the runtime environment:

- Connect as APEX_050000, SYS, SYSTEM, or any schema to which the role APEX_ADMINISTRATOR_ROLE has been granted.

Tip:
The APEX_ADMINISTRATOR_ROLE must be granted directly to a user and not through another database role.

- Run the workspace import file.
If the workspace export file was created with a version of Oracle Application Express lower than 3.2, you must connect as APEX_050000.

3. Export and then import your application using SQL*Plus in to the runtime environment. See "Exporting an Application and Related Files" in Oracle Application Express Application Builder User's Guide.

2.12 Managing Schemas

Note:
Functionality in the Administration Services application is not available in Oracle Database Cloud Service (Database Schema).

This section describes how to manage the schemas within an Oracle Application Express instance.

- What Is the Oracle Application Express Engine Schema?

- Determining the Oracle Application Express Engine Schema

- Understanding Oracle Default Schema Restrictions

See Also:
"Viewing the Parsing Schemas Report" and "Managing Workspace to Schema Assignments"

2.12.1 What Is the Oracle Application Express Engine Schema?

A schema is a logical container for the database objects. Instance administrators may need to perform certain actions within the Application Express engine schema. For example, in order for an Instance administrator to have the ability to assign Oracle default schemas, the database administrator (DBA) must explicitly grant the privilege by running the APEX_SITE_ADMIN.UNRESTRICT_SCHEMA procedure within the Application Express engine.

See Also:
"Understanding Oracle Default Schema Restrictions" for information about the APEX_SITE_ADMIN.UNRESTRICT_SCHEMA procedure

2.12.2 Determining the Oracle Application Express Engine Schema

See Also:
"Understanding Oracle Default Schema Restrictions" for information about the APEX_SITE_ADMIN.UNRESTRICT_SCHEMA procedure

To determine the current Application Express engine schema for your Oracle Application Express instance:

1. Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS. For example:

- On Windows:

SYSTEM_DRIVE:\ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password

- On UNIX and Linux:

$ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password

2. Run the following query in a schema with DBA privileges (for example, SYSTEM).

SELECT DISTINCT TABLE_OWNER FROM all_synonyms
WHERE SYNONYM_NAME = 'WWV_FLOW' and OWNER = 'PUBLIC'

2.12.3 Understanding Oracle Default Schema Restrictions

This section explains how to grant and revoke privileges.

- About Assigning Oracle Default Schemas to Workspaces

- Granting the Privilege to Assign Oracle Default Schemas

- Revoking the Privilege to Assign Oracle Default Schemas

- Working with Restricted Schemas

- Determining the Privilege Status

2.12.3.1 About Assigning Oracle Default Schemas to Workspaces

When Oracle Application Express installs, the Instance administrator does not have the ability to assign Oracle default schemas to workspaces. Default schemas such as SYS, SYSTEM, and RMAN are reserved by Oracle for various product features and for internal use. Access to a default schema can be a very powerful privilege. For example, a workspace with access to the default schema SYSTEM can run applications that parse as the SYSTEM user.

In order for an Instance administrator to have the ability to assign most Oracle default schemas to workspaces, the database administrator (DBA) must explicitly grant the privilege using SQL*Plus to run a procedure within the APEX_INSTANCE_ADMIN package. Note, however, that beginning with Oracle Application Express release 3.1, the SYS and SYSTEM schemas may no longer be used by workspaces as parsing schemas.

Note:
All schema and workspace names used as arguments to procedures in the APEX_INSTANCE_ADMIN package are used exactly as they are provided by the caller.
For example, if you pass an argument value such as p_schema =>'system', the lower-case schema name 'system' is recorded and referenced. This example could return unexpected results if you really meant to reference the common schema name SYSTEM, which would be referenced using upper case.

2.12.3.2 Granting the Privilege to Assign Oracle Default Schemas

The DBA can grant an Instance administrator the ability to assign Oracle schemas to workspaces by using SQL*Plus to run the APEX_INSTANCE_ADMIN.UNRESTRICT_SCHEMA procedure from within the Application Express engine schema. For example:

EXEC APEX_INSTANCE_ADMIN.UNRESTRICT_SCHEMA(p_schema => 'RMAN');
COMMIT;

This example would enable the Instance administrator to assign the RMAN schema to any workspace.

See Also:
"Determining the Oracle Application Express Engine Schema"

2.12.3.3 Revoking the Privilege to Assign Oracle Default Schemas

The DBA can revoke this privilege using SQL*Plus to run the APEX_INSTANCE_ADMIN.RESTRICT_SCHEMA procedure from within the Application Express engine schema. For example:

EXEC APEX_050000.APEX_INSTANCE_ADMIN.RESTRICT_SCHEMA(p_schema => 'RMAN');
COMMIT;

This example would prevent the Instance administrator from assigning the RMAN schema to any workspace. It does not, however, prevent workspaces that have already had the RMAN schema assigned to them from using the RMAN schema.

See Also:
"Determining the Oracle Application Express Engine Schema"

2.12.3.4 Working with Restricted Schemas

This section describes how to work with restricted schemas.

- Designating Specific Workspaces as Exceptions

- Removing Workspace Exceptions for a Schema

- Removing Schema Exceptions for a Workspace

2.12.3.4.1 Designating Specific Workspaces as Exceptions

If a schema has been designated as restricted using the CREATE_SCHEMA_EXCEPTION procedure, the DBA can designate specific workspaces as exceptions by running the APEX_INSTANCE_ADMIN.CREATE_SCHEMA_EXCEPTION procedure. For example:

EXEC APEX_050000.APEX_INSTANCE_ADMIN.CREATE_SCHEMA_EXCEPTION(p_schema => 'RMAN', p_workspace=> 'DBA_WORKSPACE');
EXEC APEX_050000.APEX_INSTANCE_ADMIN.CREATE_SCHEMA_EXCEPTION(p_schema => 'RMAN', p_workspace  => 'AUDITOR_WORKSPACE');
COMMIT;

This example would prevent the Instance administrator from assigning the RMAN schema to the workspace named AUDITOR_WORKSPACE. However this restriction only applies to workspace provisioning requests processed after the REMOVE_SCHEMA_EXCEPTION procedure has been run. If the AUDITOR_WORKSPACE has the RMAN schema assigned to it, this method would not prevent that workspace from continuing to use the schema.

2.12.3.4.2 Removing Workspace Exceptions for a Schema

The DBA can remove all workspace exceptions for a schema by using SQL*Plus to run the APEX_INSTANCE_ADMIN.REMOVE_SCHEMA_EXCEPTIONS procedure from within the Application Express engine schema. For example:

EXEC APEX_050000.APEX_INSTANCE_ADMIN.REMOVE_SCHEMA_EXCEPTIONS(p_schema => 'RMAN');
COMMIT;

This example would prevent the Instance administrator from assigning the RMAN schema to any workspaces if the RMAN schema were already restricted, but had one or more exceptions previously created for it.

2.12.3.4.3 Removing Schema Exceptions for a Workspace

The DBA can remove all schema exceptions for a workspace by using SQL*Plus to run the APEX_INSTANCE_ADMIN.REMOVE_WORKSPACE_EXCEPTIONS procedure from within the Application Express engine schema. For example:

EXEC APEX_050000.APEX_INSTANCE_ADMIN.REMOVE_WORKSPACE_EXCEPTIONS(p_workspace => 'AUDITOR_WORKSPACE');
COMMIT;

This example would prevent the Instance administrator from assigning any restricted schemas to the workspace named AUDITOR_WORKSPACE if that workspace had exceptions previously created for it for any restricted schemas.

2.12.3.5 Determining the Privilege Status

The DBA can determine the current status of the privileges by using SQL*Plus to run the script report_instance_configuration.sql in the utilities directory. For example:

To run the script report_instance_configuration.sql in the utilities directory:

1. Change to the utilities directory.

$ cd utilities

2. Connect in SQL*Plus and connect to the database where Oracle Application Express is installed as SYS, for example:

- On Windows:

SYSTEM_DRIVE:\ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password

- On UNIX and Linux:

$ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password

3. Run the following statement:

SQL> @report_instance_configuration.sql

The resulting report displays general information about the Application Express instance, including restricted schemas and schema exceptions.

2.13 Creating Workspaces

Note:
Functionality in the Administration Services application is not available in Oracle Database Cloud Service (Database Schema).

In order for a user to sign in to Oracle Application Express, they sign in to Oracle Application Express, they sign in to a shared work area called a workspace. An administrator can create workspaces manually or take advantage of a more automated approach in which users click a link a a login page. This section describes how an Instance administrator can create workspaces.

- About Workspaces

- About Specifying How Workspaces Are Created

- Selecting a Provisioning Mode

- How Oracle-Managed Files Effects Workspace Provisioning

- Creating a Workspace Manually

- Creating Multiple Workspaces

See Also:
"Managing Existing Workspaces"

2.13.1 About Workspaces

When users sign in to Oracle Application Express, they sign in to a shared work area called a workspace. A workspace enables multiple users to work within the same Oracle Application Express installation while keeping their objects, data and applications private. Each workspace has a unique numeric ID and name.

To make changes to a workspace, the Workspace administrators must submit a service or change requests to an Instance administrator. Only the Instance administrator can approve change requests or provision new workspaces.

See Also:
"Making a Service Request" and "Managing Workspace and Change Requests"

2.13.2 About Specifying How Workspaces Are Created

The Instance administrator determines how the process of provisioning (or creating) a workspace works for a specific Oracle Application Express instance. To determine how provisioning works, an Instance Administrator selects one of the following options on the Instance Settings page:

- Manual - In this mode, an Instance administrator creates new workspaces and notifies the Workspace administrator of the login information.

- Request - Users request workspaces directly in a self-service fashion. Users click a link on the login page to access a request form. After the workspace request has been granted, users are automatically emailed the appropriate login information.

- Request with Email Verification - In this mode, users request workspaces directly by clicking a link on the login page to access a request form. Each user receives an initial email containing a verification link. When the user clicks the verification link, the request is processed. The user can then access the workspace using the Sign In page.

Note:
To enable users to request a workspace using a link on the Login page, you must choose the provisioning status of Request or Request with Email Verification as described in the previous section. If the provisioning status is set to Manual, no link appears on the login page.

See Also:
"Selecting a Provisioning Mode," "Disabling Email Provisioning," "Configuring Email," and "Managing Workspace and Change Requests"

2.13.3 Selecting a Provisioning Mode

To select a provisioning mode:

1. Sign in to Oracle Application Express Administration Services. See "Accessing Oracle Application Express Administration Services."

2. Click Manage Instance.

3. Under Instance Settings, click Instance Settings.

4. Under Self Service, select a provisioning status:

- Manual - An Instance administrator manually creates new workspaces and notifies the Workspace administrator of the login information.

- Request - Users request workspaces directly in a self-service fashion. Selecting this option displays a link on the Login page enabling users to request a workspace. When a user requests a workspace, each request is submitted to a queue for approval. When the request is approved, the user is sent an email containing login credentials (the workspace name, username, and password).

- Request with Email Verification - In this mode, users request workspaces directly by clicking a link on the Sign In page to access a request form. Each user receives an initial email containing a verification link. When the user clicks the verification link, the request is processed. The user can then access the workspace using the Sign In page.

Tip:
If you select Request with Email Verification, you can disable workspace provisioning and send users a message. See "Disabling Email Provisioning."

5. If you select Request or Request with Email Verification:

- Development Service URL - Enter a URL for the service (optional). This value is used in the email when the request is approved. If this setting is not present, the URL is derived from your environment.

- Require Verification Code - Determines if a verification code displays and is required during the request process. Select Yes or No.

6. Click Apply Changes.

Note:
To enable users to request a workspace using a link on the Login page, you must choose the provisioning status of Request or Email Verification as described in the previous procedure. If the provisioning status is set to Manual, no link appears on the login page.

When an Instance administrator creates a new workspace with a new schema, a new tablespace and data file are created for that schema. If Oracle-Managed Files is enabled, it manages the data file for the new tablespace.

Using Oracle-managed files simplifies the administration of the Oracle database and eliminates the need for the database administrator (DBA) to directly manage the operating system files that comprise the database. Using Oracle-managed files, the DBA specifies operations in terms of database objects rather than file names. The data file for the new tablespaces are named according to the Oracle-managed files conventions. The placement of these files is determined by the database initialization parameter DB_CREATE_FILE_DEST.

If the Oracle-Managed Files is not enabled, the data file is created in the same directory as the first data file of the tablespace in which Oracle Application Express is installed.

- Identifying Inactive Workspaces

- Deleting Workspaces in a Full Development Environment

- Deleting Workspaces in a Runtime Development Environment

2.14.2.1 Identifying Inactive Workspaces

This section describes how to identify inactive workspaces.

- How to Identify Inactive Workspaces

- Identifying Inactive Workspaces By Checking Recent Updates

- Viewing Workspaces with Only a Sample Application

- Removing the Resources Associated with Inactive Workspaces

- Deleting Inactive Workspaces

2.14.2.1.1 How to Identify Inactive Workspaces

If you are managing a large hosted Oracle Application Express instance, manually deleting inactive workspaces can free up resources for other users. The process of manually deleting inactive workspaces consists of the following steps:

- Step 1: Identify inactive workspaces. See "Identifying Inactive Workspaces By Checking Recent Updates" and "Viewing Workspaces with Only a Sample Application."

- Step 2: Remove the resources (that is, the database schemas, tablespaces, and data files) associated with each inactive workspace. See "Removing the Resources Associated with Inactive Workspaces."

- Step 3: Drop the inactive workspaces from Oracle Application Express. See "Deleting Inactive Workspaces."

Tip:
To systematically purge inactive workspaces you must configure Workspace Purge settings. See "Purging Inactive Workspaces."

2.14.2.1.2 Identifying Inactive Workspaces By Checking Recent Updates

The first step in determining if a workspace is inactive is to establish some basic rules. A common approach is to base the rules on the Oracle Application Express activity records found in the current Application Express engine schema.

See Also:
"Determining the Oracle Application Express Engine Schema"

The following DDL (data definition language) creates a table of all workspaces requested before June 28, 2004 but that have been inactive since June 10, 2004. In this example, inactivity is determined by checking a key within the Application Express engine schema for the most recent updates by each workspace.

ALTER SESSION SET CURRENT_SCHEMA = APEX_050000;
CREATE TABLE ws_to_purge AS
SELECT c.security_group_id, c.company_name, c.admin_email, c.request_date,
SYSDATE last_updated_on, 'Y' ok_to_delete
FROM wwv_flow_provision_company c
WHERE
c.request_date <= to_date('20040628','YYYYMMDD') AND
(  not exists
(SELECT NULL /* Activity Log */
FROM wwv_flow_activity_log l
WHERE l.security_group_id = c.security_group_id
AND l.time_stamp > to_date('20040610','YYYYMMDD'))
)
AND NOT EXISTS
(SELECT NULL /* workspace applications */
FROM wwv_flows f
WHERE f.security_group_id = c.security_group_id
AND f.last_updated_on > to_date('20040610','YYYYMMDD'))
AND NOT EXISTS
(SELECT NULL /* Pages */
FROM wwv_flow_steps s
WHERE s.security_group_id = c.security_group_id
AND s.last_updated_on > to_date('20040610','YYYYMMDD'))
AND NOT EXISTS
(SELECT NULL /* Regions */
FROM wwv_flow_page_plugs p
WHERE p.security_group_id = c.security_group_id
AND p.last_updated_on > to_date('20040610','YYYYMMDD'))
AND NOT EXISTS
(SELECT NULL /* Items */
FROM wwv_flow_step_items i
WHERE i.security_group_id = c.security_group_id
AND i.last_updated_on > to_date('20040610','YYYYMMDD'))
AND NOT EXISTS
(SELECT NULL /* Templates */
FROM wwv_flow_templates t
WHERE t.security_group_id = c.security_group_id
AND t.last_updated_on > to_date('20040610','YYYYMMDD'))
AND NOT EXISTS
(SELECT NULL /* Files uploaded */
FROM wwv_flow_file_objects$ o
WHERE o.security_group_id = c.security_group_id
AND o.created_on > to_date('20040610','YYYYMMDD'))
AND NOT EXISTS
(SELECT NULL /* SQL Workshop history */
FROM wwv_flow_sw_sql_cmds s
WHERE s.security_group_id = c.security_group_id
AND s.created_on > to_date('20040610','YYYYMMDD'));

2.14.2.1.3 Viewing Workspaces with Only a Sample Application

Another way to identify potentially inactive workspaces is to view the Workspaces with Only Sample Application report.

To view a report or workspaces only containing only a sample application:

1. Sign in to Oracle Application Express Administration Services. See "Accessing Oracle Application Express Administration Services."

2. Click Manage Workspaces.

3. Under Workspace Reports, click Workspaces with Only Sample Application.
The Workspaces with Only Sample Applications page appears.

This page displays as an interactive report. To customize the report, use the Search bar at the top of the page.

2.14.2.1.4 Removing the Resources Associated with Inactive Workspaces

After you have identified inactive workspaces in a single table, the next step is to remove them.

Note:
Before removing the schemas, tablespaces, or data files associated with inactive workspaces, make sure these resources are not being used in any other workspace or application.

To remove the resources associated with inactive workspaces:

1. Identify the schemas used by the workspaces to be deleted by joining the table containing the identified inactive workspaces to wwv_flow_company_schemas.

2. Drop the schemas, tablespaces, and data files used exclusively by the inactive workspaces from the database. You can identify the schemas to drop by running a query similar to the following:

SELECT s.schema
FROM ws_to_purge ws,
wwv_flow_company_schemas s
WHERE s.security_group_id = ws.security_group_id
AND ws.ok_to_delete = 'Y';

2.14.2.1.5 Deleting Inactive Workspaces

Once you remove the resources associated with an inactive workspace, you can delete the workspace. You can delete inactive workspaces manually using the Oracle Application Express Administration Services application. Or, you can delete them programmatically as shown in the following PL/SQL example.

BEGIN
FOR c1 IN (SELECT security_group_id
FROM ws_to_purge
WHERE ok_to_delete = 'Y')
LOOP
WWV_FLOW_PROVISIONING.TERMINATE_SERVICE_BY_SGID(c1.security_group_id);
END LOOP;
END;

2.14.2.2 Deleting Workspaces in a Full Development Environment

BEGIN
APEX_INSTANCE_ADMIN.REMOVE_WORKSPACE(WORKSPACE_NAME, DROP_USER, DROP_TABLESPACE)
END;

Where:

- WORKSPACE_NAME is the name of the workspace.

- DROP_USER is either Y or N. The default is N.

- DROP_TABLESPACE is either Y or N. The default is N.

2.14.3 Locking a Workspace

Instance administrators can lock a workspace to address security or performance issues. Locking a workspace immediately locks all workspace administrator, developer, and user accounts in the workspace. It also changes the status of all applications in the workspace to Unavailable.

Warning:
Locking a workspace makes it permanently inaccessible.

To lock a workspace:

1. Sign in to Oracle Application Express Administration Services. See "Accessing Oracle Application Express Administration Services."

2. Click Manage Workspaces.

3. Under Workspace Actions, click Lock Workspace.

4. For Workspace, select the workspace you want to lock and click Next.

5. Review the information about applications and users and click Lock Workspace.

2.14.4 Managing Workspace to Schema Assignments

When users sign in to Oracle Application Express, they access a shared work area called a workspace. Each workspace can have multiple associated (or mapped) schemas. By associating a workspace with a schema, developers in that workspace can create new database objects in that schema and build applications that interact with the database objects in that schema.

The section describes how Instance administrators can view, edit, and remove schema and workspace assignment, associate additional schemas with a workspace, and create new schemas.

2.14.8 Isolating a Workspace to Prevent Browser Attacks

This section describes how Instance administrators configure limits to isolate a workspace and prevent browser attacks.

- About Isolating a Workspace to Prevent Browser Attacks

- Configuring Workspace Isolation Attributes

See Also:
"Isolating All Workspaces in an Instance" and "About Isolating Workspaces" in Oracle Application Express Application Builder User's Guide

2.14.8.1 About Isolating a Workspace to Prevent Browser Attacks

Isolating workspaces is an effective approach to preventing browser attacks. The only way to truly isolate a workspace is to enforce different domains in the URL by configuring the Allow Hostnames attribute. When the URLs of the attacker and the victim have different domains and hostnames, the browser's same-origin policy prevents attacks.

2.14.8.2 Configuring Workspace Isolation Attributes

To configure Workspace Isolation attributes:

1. View the existing workspace. See "Viewing Existing Workspace Information."
The Edit Information page appears.

2. Locate Workspace Isolation and edit the attributes as described in Table 2-6.

Tip:
To learn more about an attribute, see field-level Help.

Table 2-6 Workspace Isolation Attributes

Attribute

Description

Allow Hostnames

Enter a comma separated list of hostnames that can be used to access this workspace. If you leave this attribute empty, the instance-level value applies. If you enter one or more hostnames, the incoming HTTP request URL's hostname part must match one of the listed hostnames.

Resource Consumer Group

Specify the Database Resource Manager consumer group to be used for all page events associated with this workspace. If you leave this attribute empty, the instance-level value applies. At the beginning of every request, the Application Express engine switches the current consumer group of the current database session to the workspace's consumer group. This applies to both executing applications and any of the applications used within the Application Express development environment.

The privilege to switch to this consumer group must be granted to either PUBLIC or the Application Express schema. This privilege is typically granted using the procedure DBMS_RESOURCE_MANAGER_PRIVS.GRANT_SWITCH_CONSUMER_GROUP.

Maximum Concurrent Workspace Requests

Enter the maximum number of concurrent page events that Oracle Application Express supports for all applications of this workspace. If you leave this attribute empty, the instance-level value applies. Instead of processing a page event, Application Express shows an error message when the limit is already reached.

Application Express keeps track of session requests by querying the CLIENT_INFO column of GV$SESSION. This tracking will not work if developers overwrite CLIENT_INFO, e.g. with a call to DBMS_APPLICATION_INFO.SET_CLIENT_INFO.

Maximum Concurrent Session Requests

Enter the maximum number of concurrent page events that Oracle Application Express supports for each session of this workspace's applications. Instead of processing a new page event, Application Express shows an error message when the limit is already reached. Alternatively, use the Concurrent Session Requests Kill Timeout attribute to kill an active database session, to process the new page event.

Application Express keeps track of session requests by querying the CLIENT_IDENTIFIER column of GV$SESSION. This tracking will not work if developers overwrite CLIENT_IDENTIFIER, for example with a call to DBMS_SESSION.SET_IDENTIFIER.

Concurrent Session Requests Kill Timeout

If a new page event comes in that is outside the limits of Maximum Concurrent Session Requests, Application Express can execute alter system kill session on the oldest active database session which processes another page event for this Application Express session. This attribute specifies the number of seconds a database process has to be active, before it can be killed. If you leave this attribute empty, the instance-level value applies.

Warning: Killing sessions can cause problems with the application server's database session pool.

Maximum Size of Files in Workspace

Enter the total size (in bytes) of all files that can be uploaded to this workspace.

Maximum Email Messages

Enter the maximum number of email messages that can be sent with the APEX_MAIL API per 24 hour period. This value overrides the instance-level setting.

3. Click Apply Changes.

2.14.12.1 About Exporting and Importing a Workspace

To move a workspace and all associated users to a new Oracle Application Express instance, an instance administrator must export the workspace. When you export a workspace, Oracle Application Express generates a text file. This file contains information about your workspace, all the users in your workspace, and any groups in your workspace (if applicable). You can use this file to import your workspace into another Oracle Application Express instance.

Exporting a workspace and importing it into a new database instance enables developers to import application components. Therefore, to provide maximum capabilities Oracle recommends that when building new environments (for example, for production or testing) create these workspaces by importing the development workspaces.

Keep in mind, this method only imports workspace, users, and groups. This file does not contain:

- The schemas associated with this workspace or the objects in those schemas.

- Any applications, images, cascading style sheets, and static text files.

These items must be exported separately.

2.14.14 Changing Application Build Status in Administration Services

This section describes how an instance administrator can change the build status of an application.

- About Changing Application Build Status

- Changing Build Status in Administration Services

See Also:
"Managing Build Status in Workspace Administration"

2.14.14.1 About Changing Application Build Status

Every Oracle Application Express application has an application-level attribute called Build Status. You can use this attribute to prevent an application from being modified by other developers. Build Status has two settings:

- Run and Build Application - Developers can both run and edit an application.

- Run Application Only - Developers can only run an application.

Setting the Build Status to Run Application Only is an effective way to prevent other developers from modifying it.

You can change the Build Status of an application as follows:

- Developers and administrators can change the Build Status attribute on the Edit Application page. See "Availability" in Oracle Application Express Application Builder User's Guide.

- Workspace administrators can change the Build Status of applications within the current workspace on the Manage Application Build Status page. See "Changing Build Status for Multiple Applications."

- Instance administrators can change the Build Status of an application on the Build Status page as described in "Changing Build Status in Administration Services."

2.14.14.2 Changing Build Status in Administration Services

To change a Build Status in Administration Services:

1. Sign in to Oracle Application Express Administration Services. See "Accessing Oracle Application Express Administration Services."

This page displays as an interactive report. To customize the report, use the Search bar at the top of the page.

4. Click the Edit icon adjacent to the appropriate workspace.
The Edit Build Status page appears.

5. Select an alternate build status and click Apply Changes.

Tip:
Note that if you select Build Application Only during deployment, the only way to change this setting is change it on the Build Status page in Oracle Application Express Administration Services.

2.14.15 Viewing the Parsing Schemas Report

Instance administrators can use the Parsing Schemas report to identify the current parsing schema of each application in any workspace. This attribute identifies the Oracle database schema whose privileges are used when Application Express dynamically executes the application's SQL and PL/SQL code at runtime.

To view the Parsing Schemas report:

1. Sign in to Oracle Application Express Administration Services. See "Accessing Oracle Application Express Administration Services."

2. Click Manage Workspaces.

3. Under Manage Applications, click Parsing Schemas.
The Parsing Schemas page appears.

This page displays as an interactive report. To customize the report, use the Search bar at the top of the page.

- About Application Accounts Authentication

- About Application Express User Roles

- Creating New User Accounts in Administration Services

- Editing an Existing User Account in Administration Services

- Deleting User Accounts in Administration Services

See Also:
"Workspace and Application Administration," "Managing Users in a Workspace," and "Application Express Account Credentials" in Oracle Application Express Application Builder User's Guide

2.15.1 About the Advantages of Managing Users at the Instance Level

When setting up user accounts, instance administrators can take advantage of security capabilities such locking accounts, configuring password to have a fixed lifetime, and requiring user passwords be changed on first use.

See Also:
"Configuring Security"

2.15.2 About Application Accounts Authentication

User accounts are particularly useful if your application is using Application Express Accounts authentication. Application Express Accounts is a built-in authentication method in which user accounts are created and managed in the Oracle Application Express user repository.

See Also:
"Application Express Account Credentials" in Oracle Application Express Application Builder User's Guide

2.15.3 About Application Express User Roles

To access the Oracle Application Express development environment, users sign in to a shared work area called a workspace. Users are divided into four primary roles:

- End users do not have access to development or administrative capabilities. End cannot sign into a workspace and create applications. End users can only run existing database or Websheet applications.

- Developers are users who create and edit applications.

- Workspace administrators are users who perform administrator tasks specific to a workspace such as managing user accounts, monitoring workspace activity, and viewing log files.

- Instance administrators are superusers that manage an entire hosted instance using the Application Express Administration Services application. Instance administrators manage workspace provisioning, configure features and instance settings, and manage security.

2.15.4 Creating New User Accounts in Administration Services

To create a new user account in Administration Services:

Tip:
