6 Installing Application Express and Configuring Oracle HTTP Server

Note:

mod_plsql is deprecated as of Oracle HTTP Server 12c (12.1.3). For more information, please see My Oracle Support Note 1576588.1. Oracle recommends using Oracle REST Data Services instead.

This section describes how to install Oracle Application Express by downloading a ZIP file from Oracle Technology Network (OTN) and then configuring Oracle HTTP Server with mod_plsql distributed with Oracle Database 11g or Oracle Application Server 10g and Oracle Database 12c. These instructions apply to both new and upgrade installations.

See Also:

"Web Listener Requirements" and "AboutOracle REST Data Services Configuring Oracle HTTP Server with mod_plsql with Oracle Application Express" in Oracle Application Express Application Builder User's Guide

6.1 Oracle Database Requirement

Oracle Application Express release 5.0 requires an Oracle Database Release 11.1.0.7 or later, including Enterprise Edition and Express Edition (Oracle Database XE).

6.2 About Patching Oracle Application Express

If you are already running Oracle Application Express, then check the Oracle Application Express page on the Oracle Technology Network (OTN) for information about patch set releases or later releases of Oracle Application Express:

http://www.oracle.com/technetwork/developer-tools/apex/downloads/index.html

6.3 Performing Pre-installation Tasks for Oracle Application Express

Before installing Oracle Application Express, Oracle recommends that you complete the following steps:

  1. Review and satisfy all Oracle Application Express installation requirements. See "Oracle Application Express Installation Requirements."

  2. If you are actively using Oracle Application Express and upgrading the current installation then shut down with normal or immediate priority the Oracle Database instances where you plan to install Oracle Application Express. On Oracle Real Application Clusters (Oracle RAC) systems, shut down all instances on each node.

    An alternative to shutting down the database is to prevent all users from accessing Oracle Application Express when upgrading your installation from a previous release of Oracle Application Express. Oracle only recommends this option in high availability production environments where planned outages are not available. For all other scenarios, the database should be shut down.

    To disable user access to Oracle Application Express when the existing installation uses the Oracle HTTP Server with mod_plsql, you should either shut down the Web server or disable the Application Express Database Access Descriptor of the Web server.

    Once you have prevented access from Oracle Application Express users, you should log in to SQL*Plus as SYS, connecting to the database where Oracle Application Express is installed, and query V$SESSION to ensure there are no long running sessions which would interfere with the upgrade process.

  3. Back up the Oracle Database installation.

    Oracle recommends that you create a backup of the current Oracle Database installation before you install Oracle Application Express. You can use Oracle Database Recovery Manager, which is included in the Oracle Database installation, to perform the backup.

  4. Start the Oracle Database instance that contains the target database.

    After backing up the system, you must start the Oracle instance that contains the target Oracle Database. Do not start other processes such as a Web listener. However, if you are performing a remote installation, make sure the Web listener for the remote database has started.

    Note:

    If you are connecting to a remote database, then start the Web listener.

6.4 Downloading and Installing Oracle Application Express

This section describes how to download and install Oracle Application Express. How you install Oracle Application Express depends upon by the type of database you into which you are installing. To learn more, see "Utilizing the Multitenant Architecture in Oracle Database 12c."

6.4.1 Downloading and Installing Application Express in a non-CDB or Locally in a PDB

Follow this procedure to install Oracle Application Express in a non-multitenant container database (or non-CDB) or locally in a pluggable database (PDB).

To install Oracle Application Express in a non-CDB or locally in a PDB:

  1. For installations where the development will be in English only, download the file apex_5.0_en.zip from the Oracle Application Express download page. If the development will include languages other than English, download apex_5.0.zip from the Oracle Application Express download page. See:

    http://www.oracle.com/technetwork/developer-tools/apex/downloads/index.html
    

    Note that the actual file name may differ if a more recent release has shipped since this document was published.

  2. Unzip downloaded zip file:

    • If English only, unzip apex_5.0_en.zip as follows, preserving directory names:

      • UNIX and Linux: $ unzip apex_5.0_en.zip

      • Windows: Double click the file apex_5.0_en.zip in Windows Explorer

    • If multiple languages, unzip apex_5.0.zip as follows, preserving directory names:

      • UNIX and Linux: $ unzip apex_5.0.zip

      • Windows: Double click the file apex_5.0.zip in Windows Explorer

    Note:

    You should keep the directory tree where you unzip the files short and not under directories that contain spaces. For example, within Windows unzip to C:\TEMP.
  3. Change your working directory to apex.

  4. Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS specifying the SYSDBA role. 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
      
  5. Disable any existing password complexity rules for the default profile. See "Configuring Password Protection" in Oracle Database Security Guide.

  6. Select the appropriate installation option.

    Full development environment provides complete access to the Application Builder environment to develop applications. A Runtime environment enables users to run applications that cannot be modified. To learn more, see "About the Oracle Application Express Runtime Environment."

6.4.3 Creating or Updating Your Instance Administration Account

This section describes how to create or update your Instance Administrator account.

Tip:

Skip this section if you are upgrading from a previous release of Oracle Application Express. In an upgrade scenario, the Instance Administrator account and password is preserved and carried over from the prior release.

6.4.3.1 What Is an Instance Administrator?

Instance administrators are superusers that are responsible for managing an entire Oracle Application Express instance, including managing workspace provisioning, configuring features and instance settings, and managing security. To perform these tasks, an Instance administrator signs in to the Oracle Application Express Administration Services application.

See Also:

"Oracle Application Express Administration Services" in Oracle Application Express Administration Guide

6.4.3.2 About apxchpwd.sql

Running the apxchpwd.sql script enables your to create or update your Instance Administrator account. You must run the apxchpwd.sql script in the following scenarios:

  • New Oracle Application Express installations - Run apxchpwd.sql to create an Instance Administrator account and password.

  • Converting of a runtime environment to a development environment - Run apxchpwd.sql to change the Instance Administrator account password.

  • Changing Your Instance Administrator Password -Run apxchpwd.sql to change the password for an existing Instance Administrator account.

  • Unlocking Your Instance Administrator Account - Run apxchpwd.sql to unlock an existing Instance Administrator account.

Tip:

You do not need to run apxchpwd.sql when upgrading from a previous release of Oracle Application Express. In an upgrade scenario, the Instance Administrator account password is preserved and carried over from the prior release.

6.4.3.3 Running apxchpwd.sql

To create or update your Instance Administrator account:

  1. Change your working directory to the apex directory where you unzipped the installation software.

  2. Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS specifying the SYSDBA role. 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 apxchpwd.sql. For example:

    @apxchpwd.sql
    

    Follow the on-screen instructions. You will be prompted provide a username, password, and email address. If the account username does not exist, it will be created for you.

Oracle Database PL/SQL Language Reference for more information about SQL*Plus

6.4.4 Restarting Processes

After you install Oracle Application Express, you must restart the processes that you stopped before you began the installation. In addition, restart Oracle HTTP Server.

6.4.5 Configuring the APEX_PUBLIC_USER Account

It is important to correctly configure the APEX_PUBLIC_USER account to enable proper operation of Oracle Application Express.

6.4.5.1 About the APEX_PUBLIC_USER Account

The APEX_PUBLIC_USER account is created with a random password in a new installation of Oracle Application Express. You must change the password for this account before configuring the database access descriptor (DAD) in a new installation.

6.4.5.2 Unlocking the APEX_PUBLIC_USER Account

Tip:

If you are upgrading from a prior release of Oracle Application Express, this step is unnecessary.

To unlock the APEX_PUBLIC_USER account:

  1. Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS specifying the SYSDBA role. If you are configuring an Oracle Database 12c CDB, make sure you are connected to the root container, CDB$ROOT when completing this step.

    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 statement:

    ALTER USER APEX_PUBLIC_USER ACCOUNT UNLOCK
    

6.4.5.3 Changing the Password for the APEX_PUBLIC_USER Account

Tip:

If you are upgrading from a prior release of Oracle Application Express, this step is unnecessary.

To change the password for the APEX_PUBLIC_USER account:

  1. Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS specifying the SYSDBA role. If you are configuring an Oracle Database 12c CDB, make sure you are connected to the root container, CDB$ROOT when completing this step.

    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 statement:

    ALTER USER APEX_PUBLIC_USER IDENTIFIED BY new_password
    

    Where new_password is the new password you are setting for APEX_PUBLIC_USER. You will use this password when creating the DAD in the sections that follow.

6.4.5.4 About Password Expiration in Oracle Database 11g

In the default profile in Oracle Database 11g, the parameter PASSWORD_LIFE_TIME is set to 180. If you are using Oracle Database 11g with Oracle Application Express, this causes the password for APEX_PUBLIC_USER to expire in 180 days. As a result, your Oracle Application Express instance will become unusable until you change the password.

To prevent this behavior, create another profile in which the PASSWORD_LIFE_TIME parameter is set to unlimited and alter the APEX_PUBLIC_USER account and assign it to the new profile.

See Also:

Oracle Database Security Guide for information on creating profiles and assigning them to database users.

6.5 Configuring the Oracle HTTP Server

This section describes how to configure Oracle HTTP Server with mod_plsql.

6.5.1 About Copying the Images Directory

Whether you are loading a new installation or upgrading from a previous release, you must copy the images directory from the top level of the apex\images directory, for example C:\TEMP, to the location on the file system containing the Oracle home for Oracle HTTP Server.

During an upgrade, you overwrite your existing images directory. Before you begin the upgrade, to ensure that you can revert to the previous version, Oracle recommends that you create a copy of your existing images directory for Oracle Application Express, indicating the release number of the images (for example, images_3_1).

6.5.2 Copying the Images Directory

To locate the images directory on the file system, review the following files for the text alias /i/:

  • Oracle HTTP Server distributed Oracle9i Release 2—see the httpd.conf file.

  • Oracle Application Server 10g—see the marvel.conf or dads.conf files.

  • Oracle HTTP Server distributed with Oracle Database 11g or 12c —see the marvel.conf or dads.conf files.

When you locate the images directory path, rename the existing images directory to a backup location. Doing so enables you to revert to the previous release, if that becomes necessary.

Use the following command syntax to copy the apex\images directory from the Oracle Database home to a path in the Oracle HTTP Server home:

  • Oracle HTTP Server distributed with Oracle Database 12c:

    • Windows:

      xcopy /E /I APEX_HOME\apex\images ORACLE_HTTPSERVER_HOME\user_projects\domains\base_domain\images
      
    • UNIX and Linux:

      cp -rf $APEX_HOME/apex/images ORACLE_HTTPSERVER_HOME/user_projects/domains/base_domain
      

In the preceding syntax examples:

  • APEX_HOME is the location of where the installation Zip file was unzipped

  • ORACLE_HTTPSERVER_HOME is the existing Oracle Application Server or Oracle HTTP Server Oracle home

6.5.3 Editing the dads.conf File

The dads.conf file contains the information about the Database Access Descriptor (DAD) to access Oracle Application Express.

Note:

Within the context of this document, ORACLE_HTTPSERVER_HOME is the location where Oracle HTTP Server is installed.

To edit the dads.conf file:

  1. Use a text editor and open the dads.conf.

    • Oracle Application Server 10g:

      • Windows:

        ORACLE_HTTPSERVER_HOME\Apache\modplsql\conf\dads.conf
        
      • UNIX and Linux:

        ORACLE_HTTPSERVER_HOME/Apache/modplsql/conf/dads.conf
        
    • Oracle HTTP Server distributed with Oracle Database 11g:

      • Windows:

        ORACLE_INSTANCE\config\OHS/ohs<1>\mod_plsql
        
      • UNIX and Linux:

        ORACLE_INSTANCE/config/OHS/ohs<1>/mod_plsql
        
    • Oracle HTTP Server 12c:

      • Windows:

        ORACLE_HTTPSERVER_HOME\user_projects\domains\base_domain\config\fmwconfig\components\OHS\instances\ohs1\mod_plsql\dads.conf
        
      • UNIX and Linux:

        ORACLE_HTTPSERVER_HOME/user_projects/domains/base_domain/config/fmwconfig/components/OHS/instances/ohs1/mod_plsql/dads.conf
        

    Note:

    In the examples above, ohs1 refers to the name of the Oracle HTTP Server instance. When running the Oracle HTTP Server Configuration Wizard, the default name is ohs1. It may have been changed to a name other than ohs1.
  2. In the dads.conf file, replace ORACLE_HTTPSERVER_HOME, host, port, service_name, and apex_public_user_password with values appropriate for your environment. Note that the apex_public_user_password is the password you changed in "Changing the Password for the APEX_PUBLIC_USER Account."

    Note that the path listed is only an example. The path in the dads.conf file should reference the file system path described in "About Copying the Images Directory."

    Alias /i/ "ORACLE_HTTPSERVER_HOME/user_projects/domains/base_domain/images/"
    
    <Location /pls/apex>
     Order deny,allow
     AllowOverride None
     PlsqlDatabaseConnectString     host:port:service_name ServiceNameFormat
     PlsqlNLSLanguage               AMERICAN_AMERICA.AL32UTF8
     PlsqlAuthenticationMode        Basic
     SetHandler                     pls_handler
     PlsqlDocumentTablename         wwv_flow_file_objects$
     PlsqlDatabaseUsername          APEX_PUBLIC_USER
     PlsqlDefaultPage               apex
     PlsqlDatabasePassword          apex_public_user_password
     PlsqlRequestValidationFunction wwv_flow_epg_include_modules.authorize
     PlsqlPathAlias r
     PlsqlPathAliasProcedure wwv_flow.resolve_friendly_url
     Allow from all
    </Location>
    

    Note:

    PlsqlPathAlias and PlsqlPathAliasProcedure are required new parameters that must be added to an existing DAD. This is important when upgrading to Application Express release 5.0.
  3. Locate the line containing PlsqlNLSLanguage.

    The PlsqlNLSLanguage setting determines the language setting of the DAD. The character set portion of the PlsqlNLSLanguage value must be set to AL32UTF8, regardless of whether the database character set is AL32UTF8. For example:

    ...
    PlsqlNLSLanguage            AMERICAN_AMERICA.AL32UTF8
    ...
    
  4. Save and exit the dads.conf file.

6.5.4 Configuring Static File Support

Oracle Application Express enables application developers to include static files with their applications. Static files can be associated with a workspace, an application, a plug-in, or an application theme. When using the Oracle HTTP Server as your web listener, static files are served using Path Aliasing functionality of the mod_plsql plug-in.

See Also:

"Editing the dads.conf File" for the required configuration parameters

6.5.5 Stopping and Restarting Oracle HTTP Server

This section describes how to stop and restart Oracle HTTP Server.

6.5.5.1 Stopping and Restarting Oracle HTTP Server with Oracle Database 10g and Lower

Note:

Within the context of this document, ORACLE_HTTPSERVER_HOME is the location where Oracle HTTP Server is installed.

To stop and restart Oracle HTTP Server:

  • Windows:

    Execute the following:

    ORACLE_HTTPSERVER_HOME\opmn\bin\opmnctl stopproc ias-component=HTTP_Server
    ORACLE_HTTPSERVER_HOME\opmn\bin\opmnctl startproc ias-component=HTTP_Server
    
  • UNIX and Linux

    Execute the following:

    ORACLE_HTTPSERVER_HOME/opmn/bin/opmnctl stopproc ias-component=HTTP_Server
    ORACLE_HTTPSERVER_HOME/opmn/bin/opmnctl startproc ias-component=HTTP_Server
    

Note:

If you are using Oracle HTTP Server that is included with Oracle Fusion Middleware 11.1.1, you may need to replace the ias-component name above if the name given to the component was something other than HTTP_Server when it was installed. The default name is ohs1.

6.5.5.2 Stopping and Restarting Oracle HTTP Server 12c

To stop and restart the Oracle HTTP Server distributed with Oracle Database 12c, enter commands using the following syntax, where DOMAIN_HOME is the path to the Oracle HTTP Server domain:

  • Windows:

    Execute the following:

    %DOMAIN_HOME%\bin\stopComponent.cmd componentName
    %DOMAIN_HOME%\bin\startComponent.cmd componentName
    
  • UNIX and Linux

    Execute the following:

    $DOMAIN_HOME/bin/stopComponent.sh componentName
    $DOMAIN_HOME/bin/startComponent.sh componentName
    

In a default installation, componentName is ohs1 but may have been changed when running the Oracle HTTP Server Configuration Wizard.

"Creating an OHS Instance" in Administering Oracle HTTP Server

6.5.6 Disabling Oracle XML DB Protocol Server

If you were previously using the Embedded PL/SQL Gateway and now want to use Oracle HTTP server and mod_plsql, you need to disable the Oracle XML DB Protocol Server.

To disable Oracle XML DB Protocol Server:

  1. Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS specifying the SYSDBA role. 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 command:

    EXEC DBMS_XDB.SETHTTPPORT(0);
    

6.5.7 About Configuring Oracle HTTP Server Behind a Reverse Proxy or Load Balancer

When Oracle Application Express is running behind a reverse proxy or load balancer, it is important to communicate the original HTTP hostname and protocol as seen by user's browser to the Application Express engine. The engine will use this information to generate valid URL in HTML responses and HTTP redirects that user's browser can successfully follow. For Oracle HTTP server and mod_plsql, use PlsqlCGIEnvironmentList directive in the dads.conf configuration file. For example:

PlsqlCGIEnvironmentList REQUEST_PROTOCOL=https
PlsqlCGIEnvironmentList HTTP_HOST=www.example.com:443

6.6 Enabling Network Services in Oracle Database 11g or Later

6.6.1 When and Why Network Services Must be Enabled

By default, the ability to interact with network services is disabled in Oracle Database 11g Release 1 or 2 or later. Therefore, if you are running Oracle Application Express with Oracle Database 11g Release 1 or 2 or later, you must use the new 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.

    Users can call methods from the APEX_MAIL package, but issues arise when sending outbound email.

  • Using Web services in Oracle Application Express.

  • PDF report printing.

Tip:

To run the examples described in this section, the compatible initialization parameter of the database must be set to at least 11.1.0.0.0. By default a 11g database will already have the parameter set properly, but a database upgraded to 11g from a prior version may not. See "Creating and Configuring an Oracle Database" in Oracle Database Administrator's Guide for information about changing database initialization parameters.

6.6.2 Granting Connect Privileges Prior to Oracle Database 12c

The following example demonstrates how to grant connect privileges to any host for the APEX_050000 database user. This example assumes you connected to the database where Oracle Application Express is installed as SYS specifying the SYSDBA role.

DECLARE
  ACL_PATH  VARCHAR2(4000);
BEGIN
  -- Look for the ACL currently assigned to '*' and give APEX_050000
  -- the "connect" privilege if APEX_050000 does not have the privilege yet.

6.6.3 Granting Connect Privileges in Oracle Database 12c

Procedures CREATE_ACL, ASSIGN_ACL, ADD_PRIVILEGE and CHECK_PRIVILEGE in DBMS_NETWORK_ACL_ADMIN are deprecated in Oracle Database 12c. Oracle recommends using APPEND_HOST_ACE instead. The following example demonstrates how to grant connect privileges to any host for the APEX_050000 database user. This example assumes you connected to the database where Oracle Application Express is installed as SYS specifying the SYSDBA role.

BEGIN
    DBMS_NETWORK_ACL_ADMIN.APPEND_HOST_ACE(
        host => '*',
        ace => xs$ace_type(privilege_list => xs$name_list('connect'),
                           principal_name => 'apex_050000',
                           principal_type => xs_acl.ptype_db));
END;
/

The following example demonstrates how to provide less privileged access to local network resources. This example enables access to servers on the local host only, such as email and report servers.

BEGIN
    DBMS_NETWORK_ACL_ADMIN.APPEND_HOST_ACE(
        host => 'localhost',
        ace => xs$ace_type(privilege_list => xs$name_list('connect'),
                           principal_name => 'apex_050000',
                           principal_type => xs_acl.ptype_db));
END;
/

6.6.4 Troubleshooting an Invalid ACL Error

If you receive an ORA-44416: Invalid ACL error after running the previous script, use the following query to identify the invalid ACL:

REM Show the dangling references to dropped users in the ACL that is assigned
REM to '*'.

SELECT ACL, PRINCIPAL
  FROM DBA_NETWORK_ACLS NACL, XDS_ACE ACE
 WHERE HOST = '*' AND LOWER_PORT IS NULL AND UPPER_PORT IS NULL AND
       NACL.ACLID = ACE.ACLID AND
       NOT EXISTS (SELECT NULL FROM ALL_USERS WHERE USERNAME = PRINCIPAL);

Next, run the following code to fix the ACL:

DECLARE
  ACL_ID   RAW(16);
  CNT      NUMBER;
BEGIN
  -- Look for the object ID of the ACL currently assigned to '*'
  SELECT ACLID INTO ACL_ID FROM DBA_NETWORK_ACLS
   WHERE HOST = '*' AND LOWER_PORT IS NULL AND UPPER_PORT IS NULL;

  -- If just some users referenced in the ACL are invalid, remove just those
  -- users in the ACL. Otherwise, drop the ACL completely.
  SELECT COUNT(PRINCIPAL) INTO CNT FROM XDS_ACE
   WHERE ACLID = ACL_ID AND
         EXISTS (SELECT NULL FROM ALL_USERS WHERE USERNAME = PRINCIPAL);

  IF (CNT > 0) THEN

    FOR R IN (SELECT PRINCIPAL FROM XDS_ACE
               WHERE ACLID = ACL_ID AND
                     NOT EXISTS (SELECT NULL FROM ALL_USERS
                                  WHERE USERNAME = PRINCIPAL)) LOOP
      UPDATE XDB.XDB$ACL
         SET OBJECT_VALUE =
               DELETEXML(OBJECT_VALUE,
                         '/ACL/ACE[PRINCIPAL="'||R.PRINCIPAL||'"]')
       WHERE OBJECT_ID = ACL_ID;
    END LOOP;

  ELSE
    DELETE FROM XDB.XDB$ACL WHERE OBJECT_ID = ACL_ID;
  END IF;

END;
/

REM commit the changes.

COMMIT;

Once the ACL has been fixed, you must run the first script in this section to apply the ACL to the APEX_050000 user. See "Granting Connect Privileges Prior to Oracle Database 12c."

6.7 Performing Security Tasks

Oracle highly recommends you configure and use Secure Sockets Layer (SSL) to ensure that passwords and other sensitive data are not transmitted in clear text in HTTP requests. Without the use of SSL, passwords could potentially be exposed, compromising security.

SSL is an industry standard protocol that uses RSA public key cryptography in conjunction with symmetric key cryptography to provide authentication, encryption, and data integrity.

6.8 Controlling the Number of Concurrent Jobs

This section explains how to specify the number of concurrently running jobs.

6.8.1 About Managing the Number of Concurrent Jobs

JOB_QUEUE_PROCESSES determine the maximum number of concurrently running jobs. In Oracle Application Express transactional support and SQL scripts require jobs. If JOB_QUEUE_PROCESSES is not enabled and working properly, you cannot successfully execute a script.

6.8.2 Viewing the Number of JOB_QUEUE_PROCESSES

This section describes three ways to view the number of JOB_QUEUE_PROCESSES:

6.8.2.1 Viewing JOB_QUEUE_PROCESSES in the Installation Log File

After installing or upgrading Oracle Application Express to Release 5.0, you can view the number of JOB_QUEUE_PROCESSES in the installation log files. See "Reviewing a Log of an Installation Session."

6.8.2.2 Viewing JOB_QUEUE_PROCESSES in Oracle Application Express

You can view the number of JOB_QUEUE_PROCESSES on the About Application Express page.

To view the About Application Express page:

  1. Sign in to Oracle Application Express. See "Signing In to Your Workspace."

  2. Locate the Help menu at the top of the page.

  3. From the Help menu, select About.

    The About Application Express page appears. The current number JOB_QUEUE_PROCESSES displays at the bottom of the page.

6.8.2.3 Viewing JOB_QUEUE_PROCESSES from SQL*Plus

You can view the number of JOB_QUEUE_PROCESSES from SQL*Plus by running the following SQL statement:

SELECT VALUE FROM v$parameter WHERE NAME = 'job_queue_processes'

6.8.3 Changing the Number of JOB_QUEUE_PROCESSES

You can change the number of JOB_QUEUE_PROCESSES by running a SQL statement in SQL*Plus:

To update the number of JOB_QUEUE_PROCESSES:

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

    • 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. In SQL*Plus run the following SQL statement:

    ALTER SYSTEM SET JOB_QUEUE_PROCESSES = <number>
    

    For example, running the statement ALTER SYSTEM SET JOB_QUEUE_PROCESSES = 20 sets JOB_QUEUE_PROCESSES to 20.

6.9 About Running Oracle Application Express in Other Languages

The Oracle Application Express interface is translated into German, Spanish, French, Italian, Japanese, Korean, Brazilian Portuguese, Simplified Chinese, and Traditional Chinese. A single instance of Oracle Application Express can be installed with one or more of these translated versions. Developers can choose to run the Application Express development environment in any of the installed languages by simply selecting the language from the Application Builder log in screen or home page.

In order to install other languages you must use the apex_5.0.zip file which contains the extra files referenced below. If you previously downloaded apex_5.0_en.zip, then you do not need to re-install Oracle Application Express. Simply download apex_5.0.zip and unzip the file into the same directory where you unzipped apex_5.0_en.zip.

The translated version of Oracle Application Express should be loaded into a database that has a character set that supports the specific language. If you attempt to install a translated version of Oracle Application Express into a database that does not support the character encoding of the language, the installation may fail or the translated Oracle Application Express instance may appear corrupt when run. The database character set AL32UTF8 supports all the translated versions of Oracle Application Express.

You can manually install translated versions of Oracle Application Express using SQL*Plus. The installation files are encoded in AL32UTF8.

Note:

Regardless of the target database character set, to install a translated version of Oracle Application Express, you must set the character set value of the NLS_LANG environment variable to AL32UTF8 before starting SQL*Plus.

The following examples illustrate valid NLS_LANG settings for loading Oracle Application Express translations:

American_America.AL32UTF8
Japanese_Japan.AL32UTF8 

6.10 Installing Translated Versions of Oracle Application Express

This section describes installing translated versions of Oracle Application Express.

6.10.1 About Installing Translated Versions of Oracle Application Express

Whether you are installing for the first time or upgrading from a previous release, you must run the load_lang.sql script to run a translated version of Oracle Application Express.

The installation scripts are located in subdirectories identified by a language code in the unzipped distribution apex/builder. For example, the German version is located in apex/builder/de and the Japanese version is located in apex/builder/ja. Within each directory, there is a language loading script identified by the language code (for example, load_de.sql or load_ja.sql).

6.10.2 Installing a Translated Version of Oracle Application Express

To install a translated version of Oracle Application Express:

  1. Set the NLS_LANG environment variable, making sure that the character set is AL32UTF8. For example:

    • Bourne or Korn shell:

      NLS_LANG=American_America.AL32UTF8
      export NLS_LANG
      
    • C shell:

      setenv NLS_LANG American_America.AL32UTF8
      
    • For Windows based systems:

      set NLS_LANG=American_America.AL32UTF8
      
  2. Navigate to the directory under apex/builder based on the language you need to install. For example for German, navigate to apex/builder/de. Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS specifying the SYSDBA role. 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. Execute the following statement:

    ALTER SESSION SET CURRENT_SCHEMA = APEX_050000;
    
  4. Execute the appropriate language specific script. For example:

    @load_lang.sql
    

    Where lang is the specific language (for example, load_de.sql for German or load_ja.sql for Japanese).

6.11 Creating a Workspace and Adding Oracle Application Express Users

Before you can develop or install applications, you must create a workspace, add Oracle Application Express users and sign in to your workspace.

6.11.1 About Workspaces and Users

You access the Oracle Application Express home page by logging in to a workspace using a JavaScript enabled web browser. To learn more, see "Browser Requirements."

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 ID and name. An instance administrator can create a workspace manually within Oracle Application Express Administration Services or have users submit requests. Oracle Application Express Administration Services is a separate application for managing an entire Oracle Application Express instance.

See Also:

"Creating Workspaces" and "Managing Workspace and Change Requests" in Oracle Application Express Administration Guide

6.11.2 Accessing Oracle Application Express Administration Services

To manually create a workspace and user accounts, you sign in to a separate application for managing an entire Oracle Application Express instance called Oracle Application Express Administration Services. You sign in to Oracle Application Express Administration Services using the ADMIN account and password created or reset during the installation process.

To access Oracle Application Express Administration Services:

  1. In a Web browser, navigate to the Oracle Application Express Administration Services application.

    Because your setup uses Oracle HTTP Server with mod_plsql go to:

    http://hostname:port/pls/apex/apex_admin
    

    Where:

    hostname is the name of the system where Oracle HTTP Server is installed.

    port is the port number assigned to HTTP on the Oracle HTTP Server. In a default installation, this number is 7777.

    pls is the indicator to use the mod_plsql cartridge.

    apex is the database access descriptor (DAD) defined in the mod_plsql configuration file.

  2. On the Sign In page:

    Note that, depending on your setup, you might be required to change your password when you log in for the first time.

See Also:

6.12 Performing Post Installation Tasks for Upgrade Installations

Once you have verified that your upgrade installation was successful and all upgraded applications function properly, you should remove schemas from prior Oracle Application Express installations.

6.12.1 About Removing Prior Oracle Application Express Installations

The database users associated with schemas from prior installations are privileged users and should be removed when they are no longer necessary. Removing schemas from a prior installation is a two step process. First you verify if a prior installation exists and then you remove the schemas.

6.12.2 Verifying if a Prior Installation Exists

To verify if a prior installation exists:

  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:

    SELECT username  FROM dba_users  WHERE (  username LIKE 'FLOWS\_______' ESCAPE '\'       OR username LIKE 'APEX\_______' ESCAPE '\' )   AND USERNAME NOT IN ( SELECT SCHEMA                           FROM dba_registry                          WHERE comp_id = 'APEX' );
    

If the results contain entries in the form FLOWS_XXXXXX or APEX_XXXXXX where XXXXXX represents six numbers, those entries are candidates for removal.

6.12.3 Removing Schemas from Prior Installations

To remove schemas from prior installations:

  1. Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS specifying the SYSDBA role. 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. Execute a statement similar to the following example:

    DROP USER APEX_040200 CASCADE;
    

6.12.4 Fixing Invalid ACL in Oracle Database 11g or Later

After following the instructions in "About Removing Prior Oracle Application Express Installations," you may need to fix an invalid ACL if you are running Oracle Database 11g or later and you enabled network services for the prior Oracle Application Express schema.

To fix an invalid ACL:

  1. Change your working directory to the apex directory where you unzipped the installation software.

  2. Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS specifying the SYSDBA role. 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. Execute a statement similar to the following:

    EXEC DBMS_NETWORK_ACL_ADMIN.DELETE_PRIVILEGE('power_users.xml', 'FLOWS_030000');
    

6.13 About Performance Optimization Tasks

Performance of web applications heavily depends on their size and how often a browser has to request static content like images, CSS and JavaScript files. To improve performance, most web servers support on-the-fly HTTP response compression and provide settings that enable you to configure how long browsers may cache a file before requesting it again. The HTTP response compression is usually implemented using gzip encoding (for example, mod_deflate in Oracle HTTP Server), while browser file caching is enabled by issuing Cache-Control HTTP response header (for example, using mod_headers in Oracle HTTP Server).

See your web server documentation to learn how to enable response compression and browser file caching. For optimal performance of the Oracle Application Express development environment and Oracle Application Express applications, Oracle recommends enabling gzip compression of files in the virtual images directory (for example, /i/) and responses from the database access descriptor (for example, /pls/apex), as well as allowing browsers to cache files from the virtual images directory for at least 12 hours.

6.14 Converting Between Runtime and Full Development Environments

This section describes how to convert between runtime and full development environments.

6.14.1 About Runtime and Full Development Environments

An Oracle Application Express runtime environment enables users to run a production application without supporting the ability to change or edit the application. It includes only the packages necessary to run your applications, making it a more hardened environment. It does not provide a web interface for administration.

You administer an Oracle Application Express runtime environment using SQL*Plus or SQL Developer and the APEX_INSTANCE_ADMIN API.

See Also:

"About the Oracle Application Express Runtime Environment" and "Installing Exported Applications into a Runtime Environment" in Oracle Application Express Administration Guide

6.14.2 Converting a Runtime Environment to a Full Development Environment in a non-CDB or locally in a PDB

To convert an Oracle Application Express runtime environment to a full development environment in a non-CDB or locally in a PDB:

  1. Change your working directory to the apex directory where you unzipped the installation software.

  2. Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS specifying the SYSDBA role. 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 apxdvins.sql. For example:

    @apxdvins.sql
    
  4. Follow the instructions in "Creating or Updating Your Instance Administration Account."

6.14.3 Converting a Full Development Environment to a Runtime Environment in a non-CDB or locally in a PDB

Tip:

Before converting a full development environment to a runtime environment, export all Websheet applications. When you convert a development environment to runtime, existing Websheet data grids and reports will be deleted from all workspaces. Converting the environment back to a full development environment will not restore these Websheet data grids or reports.

To convert an Oracle Application Express full development environment to a runtime environment in a non-CDB or locally in a PDB:

  1. Change your working directory to the apex directory where you unzipped the installation software.

  2. Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS specifying the SYSDBA role. 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 apxdevrm.sql. For example:

    @apxdevrm.sql

6.14.5 Converting a Full Development Environment to a Runtime Environment in a CDB

Tip:

Before converting a full development environment to a runtime environment, export all Websheet applications. When you convert a development environment to runtime, existing Websheet data grids and reports will be deleted from all workspaces. Converting the environment back to a full development environment will not restore these Websheet data grids or reports.

To convert an Oracle Application Express full development environment to a runtime environment in a CDB:

  1. Change your working directory to the apex directory where you unzipped the installation software.

  2. Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS specifying the SYSDBA role. 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 apxdevrm_con.sql. For example:

    @apxdevrm_con.sql
