1 Workspace and Application Administration

In an Oracle Application Express development environment, users log in to a shared work area called a workspace. A workspace is a virtual private database that enables multiple users to work within the same Oracle Application Express installation while keeping their objects, data and applications private. This flexible architecture enables a single database instance to manage thousands of applications.

Developers can create and edit applications and view developer activity, session state, workspace activity, application, and schema reports. Workspace administrators additionally can create and edit user accounts, manage groups, and manage development services. This section describes how to perform Workspace administration tasks and access many of these reports.

This section contains the following topics:

About Workspace Administration

Oracle Application Express enables a single database to host large numbers of users. Users work in a dedicated work area called a workspace. A workspace is a virtual private database that enables multiple users to work within the same Oracle Application Express installation while keeping their objects, data and applications private. This flexible architecture enables a single database instance to manage thousands of applications.

Understanding User Roles

In the Oracle Application Express, users log in to a shared work area called a workspace. Users are divided into three primary roles:

About the Manage Services Page

You can use the Manage Services page to manage session state, caching, preferences, application models, demonstration applications, log files, service termination, schema requests, storage requests, schema reports, and log files.

The Manage Services page contains the following sections:

Accessing the Manage Services Page

To access the Manage Services Page:

  1. Navigate to the Workspace home page.

  2. Click Manage Services on the Administration list.

    The Manage Services page appears.

Managing Session State and User Preferences

A session is a logical construct that establishes persistence (or stateful behavior) across page views. Each session is assigned an 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.

Topics in this section include:

Managing Session State

A session establishes persistence (or stateful behavior) across page views. You can review session details for the current session or for recent sessions. You can also purge the current session state or purge sessions based on their age.

Topics in this section include:

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 then remove the session record or session state.

To view session details and remove session state:

  1. Navigate to the Workspace home page.

  2. Click Manage Services on the Administration list.

    The Manage Services page appears.

  3. Under Session State, click Manage Session State.

  4. Click Recent Sessions with Drill-Down to Session Details.

  5. To narrow the results, select a time frame, specify a user, and click Go.

  6. To view session details, select the session ID.

    The Session Details page appears.

  7. Click one of the following buttons:

    • 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 is removed will no longer be able to use the session and will be prompted to re-authenticate upon their next page request (in most situations). This option can be used by administrators who need to ensure a specific user can no longer access an Oracle Application Express application.

    • 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.

Enabling Login Controls for a Workspace

There are two different ways to configure login controls:

  • An Oracle Application Express administrator enables account login controls for all Application Express accounts in all workspaces across a development instance.

    If your Oracle Application Express administrator configures these preferences for an instance, those settings display as the defaults for all workspaces. See "Enabling Login Controls for All Workspaces".

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

    • Require end-user account expiration and locking

    • Set up a maximum number of failed login attempts for end-user accounts

    • Set the password lifetime for end-user accounts, that is, the number of days an end-user account password can be used before it expires

Tip:

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

To enable login controls for a workspace:

  1. Navigate to the Workspace home page.

Managing Application Express Users

Workspace administrators can create new user accounts, manage existing user accounts, and change user passwords. User accounts are particularly useful if you are using Application Express Authentication. Application Express Authentication checks the user name and password against the Oracle Application Express account repository. The Oracle Application Express account repository contains account information for developers and administrators when they log in to Oracle Application Express applications.

If the workspace administrator enables the Account Locking/Expiration feature for end user accounts, new account management attributes are exposed. Accounts may be locked, unlocked, or expired. Passwords for those accounts can also have restrictions, such as a fixed lifetime, a maximum number of consecutive incorrect passwords when attempting to log in, and a requirement to be changed on first use.

Topics in this section include:

See Also:

"Exporting Workspace Users" in Oracle Application Express Application Builder User's Guide

Creating New User Accounts

Workspace administrators can create three different types of user accounts:

  • Developers can create and edit applications and view developer activity, session state, workspace activity, application, and schema reports.

  • Workspace administrators perform administrator tasks specific to a workspace, such as managing user accounts, managing groups, altering passwords of users within the same workspace, and managing development services.

  • End users have no development privileges and can access only applications that do not use an external authentication scheme.

To create a new user account:

  1. Navigate to the Workspace home page.

  2. From the Administration list, click Manage Application Express Users.

    The Manage Application Express Users page appears.

  3. Click Create.

    The Create User page appears.

  4. Under User Identification, enter the appropriate information.

  5. Under Developer Privileges:

    • Accessible Schemas (null for all) - Enter a colon-delimited list of schemas for which this developer has permissions when using the SQL Workshop. This list of schemas restricts the user to a subset of the full set of schemas provisioned for the workspace and determines what schema names the user sees in SQL Workshop.

    • Default Schema - Identifies the default schema used for data browsing, application creation, and SQL script execution.

    • User is a developer - To add this user as a developer, select Yes. For end users, select No.

      Developers can create and modify applications and database objects and view developer activity, session state, workspace activity, application, and schema reports.

    • User is a workspace administrator - To add this user as a workspace administrator, select Yes. For developers or end users, select No.

      In addition to having developer privileges, workspace administrators can create and edit user accounts, manage groups, alter passwords of users within the same workspace, and manage development services.

      Note:

      You create end users by adding them as users but not defining them as either developers or workspace administrators, restricting their privileges.
  6. Under Account Control:

    • Set Account Availability - Select Unlocked to allow a user to log in to this account. Select Locked to prevent a user from logging in to this account. Select Unlocked to enable the account to be used.

    • Require Change of Password on First Use - Select Yes to require the user to change the password immediately after logging in with the current, temporary password.

      This rule applies to the use of this account for developers and workspace administrators. It also applies to all users who use this account when logging in to developed applications.

    Tip:

    An Oracle Application Express administrator can configure these settings for an entire Oracle Application Express instance and define password complexity policies. See "Enabling Login Controls for All Workspaces". "About Password Policies", and "Configuring Password Policies"
  7. Under User Groups, select an optional user group.

    You can use groups to restrict access to various parts of an application. Groups are primarily useful when using Application Express Authentication.

  8. Under Additional Attributes, update the user's name or add descriptive information about the user or account.

  9. Click Create User or Create and Create Another.

Editing Existing User Accounts

Workspace administrators can edit existing user accounts.

To edit an existing user account:

  1. Navigate to the Workspace home page.

Viewing Active Sessions

A session is a logical construct that establishes persistence (or stateful behavior) across page views. The Active Sessions report lists active sessions with the current workspace.

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. An active session is a session that has not yet been purged from the sessions table. A DBMS job runs every eight hours and purges session records older than 24 hours.

To view active session details:

  1. Navigate to the Workspace home page.

  2. From the Administration list, click Monitor Activity.

  3. Under Sessions, select Active Sessions.
