Known Issues

IBM JVM Updates For DST

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.

WebLogic Server Known Issues

The following sections provide information on known issues in WebLogic Server on AIX:

IIOP Thin Client Not Supported

The IIOP thin client is not supported on AIX due to dependencies on the JVM. Only thin-client applications are affected by this issue.

Workaround: Run WebLogic Server on AIX and your thin client on another operating system.

Serial Version UID Mismatch

A Serial Version UID Mismatch Issue is encountered if you deploy an application on a latest JVM, but compiled with previous Service Refresh of IBM Java 5 32-bit JDK.

Workaround: To be compatible with the serialization of previously compiled applications, modify the <BEA_HOME>/Wlserver_10.0/common/bin/commEnv.sh file to include the following command:

JAVA_OPTIONS="$JAVA_OPTIONS  -Dcom.sun.xml.namespace.QName.useCompatibleSerialVersionUID=1.0"

Alternatively, you can use the command line option:

export IBM_JAVA_OPTIONS="-Dcom.sun.xml.namespace.QName.useCompatibleSerialVersionUID=1.0"

Note: If you intend to deploy new applications with previously compiled applications, they must be recompiled as necessary to have the same Serial Version UID.

AspectJClassLoader Not Supported

The weblogic.aspects.AspectJClassLoader is not supported on AIX using IBM Java 5.

Workaround: You are advised not to use this class loader.

JVM Debug Mode Impact

Using the JVM debug mode with the IBM JVM significantly degrades application performance. Therefore, whenever you run WebLogic Portal on an AIX configuration, BEA strongly recommends that you disable the JVM debug mode (default setting for WebLogic Platform). Disabling debug mode is recommended for all domains, including existing domains and those domains created using the Configuration Wizard.

To disable JVM debug mode, do one of the following:

XML Schema Validation Error

An xml schema factory validation error is encountered when IBM JDK fails to return the platform default schema factory because of a preconfigured property file format.

Workaround: Modify the <BEA_HOME>/wlserver_10.0/common/bin/commEnv.sh file to include the following command: 

JAVA_OPTIONS="$JAVA_OPTIONS -Djavax.xml.validation.SchemaFactory:http://www.w3.org/2001/XMLSchema=org.apache.xerces.jaxp.validation.XMLSchemaFactory"

WebLogic Portal Known Issues

The following sections provide information on known issues in WebLogic Portal on AIX:

DB2 Considerations

To ensure that portal applications run correctly on DB2, you must set some minimum configuration parameters. If you do not, heavy portal activity may exceed database capacity.

Use the following settings as guidelines to configure your DB2 database:

For additional information, see Configuring DB2 Databases in the BEA WebLogic Portal 10.0 Database Administration Guide.

WebLogic Workshop 10.1 Known Issues

The generic .jar installer used to install Workshop on AIX platforms throws an OutOfMemory Exception and does not provide a complete installation.

Workaround:

Update the Java opts max heap size. For example:

     java -Xms512m -Xmx1024m -jar workshop101_generic.jar

Known Issues for Other BEA Products
