8.1 Supported Configurations: IBM AIX 5.2 on pSeries
Note: Support of IBM AIX 5.2 is no longer available. For additional information, please refer to the AIX 5.2 End of Support Announcement.
This section provides the following information:

IBM SDK 1.4.2 32-bit JavaTM 2 Runtime Environment, Standard Edition (build 1.4.2) Classic VM (build 1.4.2, J2RE 1.4.2 IBM AIX build ca1420-20040626 (JIT enabled: jitc)) |
Download the IBM SDK from the IBM Web site and install it, manually, before installing WebLogic Server. For instructions, see Download and Installation Instructions. Use of JVM debug mode with the IBM JVM significantly degrades application performance and debugging effectiveness. The JVM debug mode is enabled by default on WebLogic Platform; BEA strongly recommends that you manually disable it when running WebLogic Platform on AIX. For instructions, see JVM Debug Mode Impact. |

The WebLogic Workshop IDE and WebLogic Integration Format Builder are not supported on IBM AIX systems. IBM AIX is supported for the production deployment of applications developed in the WebLogic Workshop IDE. Debugging of applications developed in the WebLogic Workshop IDE, for deployment on AIX, should be accomplished to the extent possible on the Workshop development system; use of JVM debug mode with the IBM JVM significantly degrades application performance and debugging effectiveness. IBM AIX is also supported for the development and production deployment of WebLogic Server applications developed with other tools. |

This section provides workarounds for the following problems:
For more information about known issues with this release, see the Release Notes for WebLogic Platform 8.1 or the appropriate product component of WebLogic Platform. For a list of available Release Notes documents, see:

IBM has released a Timezone Update Utility to update DST data without the need to upgrade Java. See IBM Time Zone Update Utility for JavaTM.
The IIOP thin client is not supported on AIX due to dependencies on the JVM. Only thin-client applications are affected by this issue.
To work around this issue, run WebLogic Server on AIX and your thin client on another operating system.
The default buffer size for UDP_SENDSPACE
is 9216 (9 KB), but WebLogic Server sends fragments, up to 32 KB in size, to UDP_SENDSPACE
. As a result, use of a buffer size smaller than 32 KB may cause an I/O exception.
To prevent such I/O exceptions:
Use of the JVM debug mode with the IBM JVM significantly degrades application performance. Therefore, whenever you run WebLogic Platform on an AIX configuration, BEA strongly recommends that you disable the JVM debug mode (which, by default, is enabled by WebLogic Platform). Disabling debug mode is recommended for all domains, both existing ones and domains created using the Configuration Wizard.
If you would still like to enable JVM debug mode, see How to Enable JVM Debug Mode for the procedure.
To disable JVM debug mode, you have a choice of two methods, which are described in the following sections.
Note: If you are going to perform this procedure, you must do so before launching QuickStart.
Pass the 'nodebug
' command-line argument to the server startup script. For example:
$ ./startWebLogic.sh nodebug
Note: Enabling debug mode is not recommended because this mode affects server performance.
Note: This limitation is reported, in CR135846, in the "Known Limitations" section of the WebLogic Platform 8.1 Release Notes.
Because the Xalan transformer shipped with the IBM SDK 1.4.2 is JAXP 1.2-compliant, but WebLogic Server only supports applications based on JAXP 1.1, you must set the Transformer Factory to weblogic.apache.xalan.processor.TransformerFactoryImpl
.
To set the XML Transformer and Parser Factories, you have a choice of three methods:
A procedure for each method is provided in the following sections.
JAVA_OPTIONS
: "-Djavax.xml.transform.TransformerFactory=weblogic.apache.xalan.processor.TransformerFactoryImpl
-Djavax.xml.parsers.SAXParserFactory=weblogic.apache.xerces.jaxp.SAXParserFactoryImpl
-Djavax.xml.parsers.DocumentBuilderFactory=weblogic.apache.xerces.jaxp.DocumentBuilder
FactoryImpl"
config.xml
file. The following entries must be added:<Server Name="Server_Name"
.
.
.
XMLRegistry="SampleXMLRegistry">
SampleXMLRegistry
, as follows:<XMLRegistry Name="SampleXMLRegistry"
TransformerFactory="weblogic.apache.xalan.processor.TransformerFactoryImpl"
SAXParserFactory="weblogic.apache.xerces.jaxp.ParserFactoryImpl"
DocumentBuilderFactory="weblogic.apache.xerces.jaxp.DocumentBuilderFactoryImpl"/>

Before you can upgrade your WebLogic Platform system from 8.1 SP2 to 8.1 SP3 on AIX, you must clean out any unused libraries manually. For instructions, see the Release Notes for WebLogic Platform 8.1:

Complete the following procedures:
Complete the following procedure to download and install the IBM SDK 1.4.2 on IBM AIX (32-bit) build ca1420-20040626:
Note: Currently there is no APAR or PTF for the IBM SDK 1.4.2; you do not need to apply any patches on top of this SDK.
For caveats about using WebLogic Platform 8.1 SP3 on an IBM AIX 5.2 configuration, see Known Issues.
To install WebLogic Platform 8.1 SP3 on an IBM AIX 5.2 configuration:
http://commerce.bea.com
.jar
installation files, as described in Installing WebLogic Platform. For example, if you are installing in console mode, enter the following on the command line:$ java -jar pj_platform813_generic.jar -mode=console
For detailed instructions, see "Starting Console-Mode Installation on UNIX Systems" in Installing BEA WebLogic Platform:
http://download.oracle.com/docs/cd/E13196_01/platform/docs81/install/console.html#instcon003
Note: When using an Asian version of an installer (such as an installer for Japanese, Korean, or Simplified Chinese), you need to increase the maximum heap size to 256 MB by specifying the -Xmx256m
argument on the command line. For example, if you are using a Japanese installer, enter the following command:$ java -Xmx256m -jar pj_platform813_ja_generic.jar -mode=console
