Oracle® Application Express

Patch Set Notes

Release 4.2.1.00.08

December 2012

These patch set notes accompany the Oracle Application Express 4.2.1.00.08 patch set. The Oracle Application Express 4.2.1.00.08 patch set is a cumulative patch.

This document contains these topics:

1 Patch Set Overview

Patch sets are a mechanism for delivering fully tested and integrated product fixes. Patch sets provide bug fixes only; they typically do not include new functionality and they do not require certification on the target system. Patch sets include all of the libraries that have been rebuilt to implement the bug fixes in the set. All of the fixes in the patch set have been tested and are certified to work with each other. Patch sets contain the same set of generic fixes across all platforms. Patch sets may also include additional patches specific to the platform on which they are released.

The Oracle Application Express 4.2.1.00.08 patch set can be applied to Oracle Application Express release 4.2. Apply the patch to the Oracle database where the Oracle Application Express schemas are installed. This patch will determine if additional languages are installed, and will apply the patch for those languages as well. Oracle Application Express release 4.2 is supported on Oracle Database 10g (10.2.0.4) and later.

When determining whether or not to install this patch set, consider the following rules:

  1. If you have Oracle Application Express release 4.2 installed, download the Oracle Application Express 4.2.1 patch set and apply it.

  2. If you have Oracle Application Express release 4.1 or earlier installed (including Oracle HTML DB release 1.5), download and install the entire Oracle Application Express 4.2.1 release from the Oracle Technology Network (OTN).

  3. If you do not have Oracle Application Express installed, download and install the entire Oracle Application Express 4.2.1 release from the Oracle Technology Network (OTN).

2 Pre-Installation Tasks

Complete the following pre-installation tasks before installing the patch set.

Topics:

2.1 Identifying the Oracle Application Express Installation

This is not a complete software distribution. You must connect to an existing Oracle Database where the Oracle Application Express schemas are installed and run the apxpatch.sql installation script.

2.2 Downloading and Extracting the Installation Software

Download the patch set to a computer with access to the Oracle Database. You will also need access to the Oracle home.

To download and extract the patch set installation software:

  1. Download the p14732511_421_GENERIC.zip patch set installation archive to a directory that is not the Oracle home directory or under the Oracle home directory.

  2. Unzip and extract the installation files as follows:

    • Microsoft Windows - Double-click the p14732511_421_GENERIC.zip file

    • UNIX or Linux - Enter the following command:

      $ unzip p14732511_421_GENERIC.zip

2.3 Optionally Backing Up the Oracle Database

The Application Express engine is a collection of tables and packages that reside wholly within the Oracle Database user accounts APEX_040200 and FLOWS_FILES. This patch set updates the underlying tables and packages within the APEX_040200 account. If your installation fails, you will not be able to rollback the patch set installation process. Therefore, Oracle recommends that you perform a complete backup of your Oracle instance before you install the patch set. Note that after the patch set is installed there is no way to remove it.

If you choose to perform a backup, restart the Oracle Database in restricted session mode to prevent any user access (that is, developer and end-user) while applying the patch set.

2.4 Preventing Access to Oracle Application Express

It is important that no developers or end users access Oracle Application Express while you are applying the patch set. This section describes how to start Oracle Application Express if your configuration includes Oracle HTTP Server and mod_plsql, embedded PL/SQL gateway, or Oracle Application Express Listener.

Topics:

2.4.1 Stopping Oracle HTTP Server

If your configuration includes Oracle HTTP Server and mod_plsql, you need to stop Oracle HTTP Server. To stop Oracle HTTP Server shipped with Oracle Database 10g release 1 (10.1) or later, enter commands using the following syntax, where ORACLE_BASE is the path to the Oracle base directory:

ORACLE_BASE\ORACLE_HTTPSERVER_HOME\opmn\bin\opmnctl stopproc ias-component=HTTP_Server

Note that if the Oracle HTTP Server is listening on a port less than 1024, then these commands must be executed as a privileged user (such as root).

2.4.2 About Disabling HTTP on the Oracle XML DB Protocol Server

If your configuration includes the embedded PL/SQL gateway, you need to disable the HTTP on the Oracle XML DB Protocol Server. The embedded PL/SQL gateway runs on the Oracle XML DB Protocol Server in the Oracle database. To disable it, you change the port number to 0. Before doing so, first verify the port number.

2.4.2.1 Verifying the Port Assigned to Oracle XML DB Protocol Server

To verify the port number assigned to HTTP on the Oracle XML DB Protocol Server:

  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. Enter the following statement to verify the port number:

    SELECT DBMS_XDB.GETHTTPPORT FROM DUAL;

    If the port number returns 0, the Oracle XML DB Protocol Server is disabled.

2.4.2.2 Disabling HTTP on the Oracle XML DB Protocol Server

To disable HTTP on the Oracle XML DB Protocol Server:

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

    • Windows:

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

    • UNIX and Linux:

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

  2. Run the following statements:

    EXEC DBMS_XDB.SETHTTPPORT(0);
COMMIT;

2.4.3 Stopping Oracle Application Express Listener

To learn more about stopping the Oracle Application Express Listener server, see Oracle Application Express Listener Installation and Configuration Guide:

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

3 Installation Tasks

Complete the following tasks to install the patch set:

  1. Set your current directory to the top-level "patch" directory where you unzipped the p14732511_421_GENERIC.zip file.

  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 apxpatch.sql. For example:

    @apxpatch.sql

  4. Review the log file apxpatch.log for any errors.

4 Post-Installation Tasks

Complete the following post-installation tasks before using the upgraded software.

Topics:

4.1 Updating the Images Directory

During an upgrade, you must incorporate the new images directory. Copy the patch/images directory into the images directory used for Oracle Application Express.

Topics:

4.1.1 Updating the Images Directory When Running Oracle HTTP Server

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

  • Oracle Application Server 10g - See the marvel.conf or dads.conf files.

  • Oracle HTTP Server distributed with Oracle Database 11g - See the marvel.conf or dads.conf files.

When you locate the images directory path, copy it to the existing ORACLE_HTTPSERVER_HOME home.

On a Windows system, run a command from a command prompt similar to the following example:

xcopy /E /I patch\images ORACLE_HTTPSERVER_HOME\Apache\Apache\images

On UNIX or Linux based systems, run a command similar to the following example:

cp -rf patch/images ORACLE_HTTPSERVER_HOME/Apache/Apache

In the preceding syntax examples, ORACLE_HTTPSERVER_HOME is the existing Oracle Application Server or Oracle HTTP Server Oracle home. The location of the Oracle Application Express images directory may be different in your configuration.

4.1.2 Updating the Images Directory When Running the Embedded PL/SQL Gateway

The images in an Oracle XML DB HTTP Server with the embedded PL/SQL gateway installation are in the XML DB repository. Updating the images is accomplished by running the SQL Script apxldimg.sql located in the top level directory where the patch was unzipped.

To update the images directory:

  1. Set your current directory to the top-level "patch" directory where you unzipped the p14732511_421_GENERIC.zip file.

  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 apxldimg.sql passing the file system path to the "patch" directory where the p14732511_421_GENERIC.zip file was unzipped as shown in the following example:

    • On Windows:

      @apxldimg.sql SYSTEM_DRIVE:\TEMP\patch

    • On UNIX and Linux:

      @apxldimg.sql /tmp/patch

4.1.3 Updating the Images Directory When Using Oracle Application Express Listener

If you are using the Oracle Application Express Listener, you need to create a Web Archive for Oracle Application Express images. For more information, see "Create the Web Archive for Oracle Application Express Images" in Oracle Application Express Listener Installation and Configuration Guide:

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

4.2 Starting Oracle Application Express

This section describes how to start Oracle Application Express if your configuration includes Oracle HTTP Server and mod_plsql, embedded PL/SQL gateway, or Oracle Application Express Listener.

Topics:

4.2.1 Starting Oracle HTTP Server

To start Oracle HTTP Server shipped with Oracle Database 10g release 1 (10.1) or later, enter commands using the following syntax, where ORACLE_BASE is the path to the Oracle base directory:

ORACLE_BASE\ORACLE_HTTPSERVER_HOME\opmn\bin\opmnctl startproc ias-component=HTTP_Server

Note that if the Oracle HTTP Server is listening on a port less than 1024, then these commands must be executed as a privileged user (such as root).

4.2.2 Enabling the Embedded PL/SQL Gateway

Once disabled, you enable the embedded PL/SQL gateway by assigning a port number to the Oracle XML DB Protocol Server.

To assign a port number to Oracle XML DB Protocol Server:

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

    • Windows:

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

    • UNIX and Linux:

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

  2. Run the following statements:

    EXEC DBMS_XDB.SETHTTPPORT(port);
COMMIT;

    For example:

    EXEC DBMS_XDB.SETHTTPPORT(8080);
COMMIT;

Note:

Port numbers less than 1024 are reserved for use by privileged processes on many operating systems. To enable the Oracle XML DB Protocol Server on a port less than 1024, such as 80, review the following documentation:

  • "Using Protocols to Access the Repository" and "Using HTTP(S) on Nonstandard Ports" in Oracle XML DB Developer's Guide.

  • "Protocol Address Configuration" and "Port Number Limitations" in Oracle Database Net Services Reference.

4.3 About Patching Oracle Application Express After Translating Languages

It is safe to apply the Oracle Application Express 4.2.1.00.08 patch set repeatedly to an Application Express 4.2 instance. If you load additional translated versions of Oracle Application Express after applying this patch, you must apply the entire patch set again.

5 Known Issues

This section describes bugs and known issues for Oracle Application Express.


Tip:

This section is current as of the writing of this document. To view the most current listing of known issues, go to the Known Issues page available off the Downloads page. See: 
http://www.oracle.com/technetwork/developer-tools/apex/downloads/index.html

 

Topics:

5.1 Developer Toolbar Not Available for Mobile Applications

The Developer toolbar is not included on jQuery Smartphone pages. After clicking Run Application from the Application Builder, the only way to return to the Application Builder is to use the browser's back button. You will need to go back once for each mobile page visited.

Solution:

Right click the Run Application button and select Open Link in New Tab or Open Link in New Window or similar text. The exact command varies by browser.


Tip:

For applications with both desktop and mobile user interfaces you can access the Session State for a mobile page by navigating to a desktop page and using the developer toolbar and then changing the page number.

 

5.2 Page Submit Actions Not Working for Some Longer Mobile Select Lists

In an application that uses a jQuery Mobile user interface, some form elements use native items when running on actual smartphone or tablet devices. Select lists are rendered using a native control as long as the LOV includes no more than 10 items. When there are more than ten items, select lists are rendered as jQuery Mobile dialogs, making it easier to find and pick a value in long lists.

Using the Page Action when Value Changed attribute to make the page submit when the value changes, only works when the native control is rendered. Once the select list is rendered as a dialog with more than 10 items, the page no longer submits. The same is also true when a dynamic action is defined to fire on 'Change' of one of these select lists, where the action is set to Submit Page.

5.2.1 Solution:

No workaround currently available.

5.3 Issues with Editing Items After Upgrade

After an upgrade users get one of the following errors when they try to edit or delete an item:

Error during rendering of page item P4311_PROTECTION_LEVEL

ORA-20001: Query must begin with SELECT or WITH

5.3.1 Solution:

Restart Oracle Application Express Listener. For more information, see Oracle Application Express Listener Installation and Configuration Guide:

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

5.4 Theme 25 Alert Region Does Not Support Multiple Page Items in the Same Row

In theme 25, it is not possible to have two items on the same row when using the Alert Region region template unless you add a Display Point to the region template.

5.4.1 Solution:

You can create a Display Point for this region template by editing the Alert Region template and in Display Points add a new Row with the following information:

  • Name: Region Body

  • Template Substitution: BODY

  • Grid Support: Checked

  • Maximum Fixed Grid Columns: -1

8 Changed Behavior

This section describes changed behavior in the Oracle Application Express 4.2.1.00.08 patch set.


Tip:

This section is current as of the writing of this document. To view the most current listing of changed behavior, go to the Known Issues page available off the Downloads page. See: 
http://www.oracle.com/technetwork/developer-tools/apex/downloads/index.html

 

Topics:

8.1 Maximum Width for Textareas

In Oracle Application Express release 4.2.0.00.27, textareas were changed to always use the Maximum Width attribute to restrict text input. Because of issues with existing applications where the Maximum Width attribute contained wrong values, this has been changed to only enforce the length restriction if the application Compatibility Mode attribute is 4.2 or higher.

8.2 Enhanced Security for Report Links

Oracle Application Express includes enhanced security for report column links, where the link contains both JavaScript and references to other report column substitutions. For example:

javascript:alert( 'Delete #NAME#' );

Where NAME is a column name in the report.

Prior to Oracle Application Express release 4.2.1, in order to protect against possible cross-site scripting vulnerabilities you would have had to explicitly escape any column values in the report source, so that they could safely be used in JavaScript links. In release 4.2.1, when running in Compatibility Mode 4.2, Oracle Application Express automatically JavaScript escapes column name substitutions referenced in JavaScript links if the column is defined to escape special characters.

Existing applications with a Compatibility Mode of less than 4.2 will not be affected. However, if you have an existing application using Compatibility Mode 4.2 and you have manually JavaScript escaped any column values that were referenced in report column links, this will now result in double escaping. To fix this, Oracle recommends that you remove the manual JavaScript escaping from your report source and use of the native escaping.

8.3 jQuery Mobile

The jQuery Mobile JavaScript library used by Oracle Application Express has been updated to version 1.2.0.

8.4 AnyChart 6

The AnyChart JavaScript libraries used by Oracle Application Express have been updated to version 6.0.11. This version includes Circular Gauge HTML5 support, and a fix for the display of maps in Chrome 21 or higher as referenced in the Oracle Application Express Installation Guide. See:

http://docs.oracle.com/cd/E37097_01/doc/doc.42/e35121/toc.htm#CACHEFDH

8.5 Resizing of Charts on Mobile Page

In Oracle Application Express release 4.2.0.00.27, charts generated on an application page with a jQuery Mobile Smartphone user interface were created with fixed width and height region settings in pixels. This meant that the chart region did not resize correctly according to the mobile device being used to render it.

With Oracle Application Express release 4.2.1, when a chart is created on a page using the jQuery Mobile Smartphone user interface, it correctly resizes to fit the device it is being rendered on. The width is automatically set to 100% of the chart region, and the height is based upon the height of the browser. This automatic resizing only occurs when the values for chart height and width on the Chart Attributes page are set to NULL. To define a fixed width and height for your chart region, you should specify values for width and height on the Chart Attributes page in pixels.
