Patch Set Notes

Release 4.1.1.00.23

 

February 2012

These patch set notes accompany the Oracle Application Express 4.1.1.00.23 patch set. The Oracle Application Express 4.1.1.00.23 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 4.1.1.00.23 patch set can be applied to Oracle Application Express release 4.1. 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 4.1 is supported on Oracle Database 10g (10.2.0.4) and higher.

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

  1. If you have Oracle Application Express release 4.1 installed, download the Oracle Application Express 4.1.1 patch set and apply it. To obtain the patch go to My Oracle Support and search for patch number 13331096.

  2. If you have Oracle Application Express release 4.0 or earlier installed (including Oracle HTML DB release 1.5), download and install the entire Oracle Application Express 4.1.1 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 4.1.1 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 p13331096_11202_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 p13331096_11202_GENERIC.zip file

    • UNIX or Linux - Enter the following command:

      $ unzip p13331096_11202_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_040100 and FLOWS_FILES. This patch set updates the underlying tables and packages within the APEX_040100 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 Disabling Oracle XML DB HTTP Server

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

To disable Oracle XML DB HTTP server:

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

    • Windows:

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

    • UNIX and Linux:

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

  2. Run the following statements:

    EXEC DBMS_XDB.SETHTTPPORT(0);
COMMIT;
2.4.2.1 Verifying the Oracle XML DB HTTP Server Port

To verify the port number where the Oracle XML DB HTTP Server is running:

  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. 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 HTTP Server is disabled.

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 Developer Guide:

http://docs.oracle.com/cd/E21611_01/doc.11/e21058/toc.htm

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 p13331096_11202_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 p13331096_11202_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 p13331096_11202_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 recursively copy the patch/images directory to the Oracle Application Express images directory setup for the Oracle Application Express Listener. For more information, see "Upgrading Oracle Application Express Images" in Oracle Application Express Listener Installation and Developer Guide:

http://docs.oracle.com/cd/E21611_01/doc.11/e21058/install.htm#CHDDEECC

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 Oracle XML DB HTTP Server

Once disabled, you enable embedded PL/SQL gateway by assigning a port number.

To enable Oracle XML DB HTTP server:

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

    • Windows:

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

    • UNIX and Linux:

      $ sqlplus /nolog
SQL> 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 XML DB HTTP listener 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.

7 Other Issues and Changes

This section describes other changes included in Oracle Application Express that are not documented elsewhere.

This section contains the following topics:

7.1 Addition of Theme 24

This patch set includes a new theme, Theme 24. Theme 24 incorporates HTML5 and CSS3 features and is based on the colors used in Oracle Public Cloud.

7.2 Changes in Page and Region Caching

Because of bug 13722696, this release includes the following changed behavior for page and region caching:

  1. If a cached region or a cached page contains protected page items of the following types, it will never be cached independent of the specified cache settings:

    • Hidden where Value Protected is set to Yes.

    • Display Only where Save Session State is set to Yes.

    • Text Field where Disabled is set to Yes and Save Session State is set to Yes.

    • Page Items where the read only condition evaluates to true.

  2. If the URL which is used to render a page contains application or page items which are set in session state (for example, f?p=631:7:609442841545301::::P7_CUSTOMER_ID:7 ) then the existing regions or page caches will not be used and no new caches are stored independent of the specified cache settings.

  3. If the application is running in debug mode, caches are now used. Previously, Debug mode always disabled caching.

7.3 Columns Used in Automatic Row Processing (DML) Processes

Because of bug 12990445, the following changes have been implemented for Automatic Row Processing (DML) process types. The code which performs the INSERT has been changed to determine if the columns should be included in the INSERT statement. Note that these are the same checks which occur before an UPDATE. These new checks include:

  • Is the source type a DB Column?

  • Does the specified Build Option have a status of Include or is it not specified at all?

  • Is the page item contained in the POST request? For example, if the page item is conditional it will not be contained in the POST request if the condition evaluates to FALSE during page rendering.

  • Is the page item not of type Display Only where Save State is set to No?

The above new behavior is used for all new applications which are created in Oracle Application Express release 4.1.1.

For existing applications where the compatibility mode is set to 4.0, the old behavior of including all page items will still be used to prevent breaking existing applications.

To change an old application to use compatibility mode 4.1, run the following statement in SQL Workshop, SQL Commands:

begin 
apex_util.set_compatibility_mode(<application id>, '4.1); 
commit; 
end;

To learn more, see "SET_COMPATIBILITY_MODE Procedure" in the Oracle Application Express API Reference:
