Known Issues

Doing a Complete Install With a Generic Installer

If you are performing a complete install of a WebLogic product (e.g. WebLogic Server, WebLogic Portal) by using the generic installer (.jar) on a platform where Eclipse is not supported or not installed, you might encounter a situation where the generic installer will go into a repeated loop condition. If you are experiencing this condition refer to the Installation Guide, specifically the "Install Eclipse Location Options" section for more information on how to handle the installation.

Serial Version UID Mismatch

A Serial Version UID Mismatch Issue may be encountered if you deploy an application on a latest JVM, but compiled with an earlier JDK release.

Workaround: To be compatible with the serialization of previously compiled applications, modify the <BEA_HOME>/wlserver_10.3/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 JAVA_OPTIONS="$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.

JVM Stack Overflow

You might encounter a JVM stack overflow error or exception while running WebLogic Server. This issue applies to Oracle Enterprise Linux 4, 5, 5.1 on AMD64 and 64-bit Xeon platforms.

Workaround: Increase the stack size from the default 128k to 256k.

Issues Related to WebLogic Integration 10.3 Using 64-bit JDK

When you install WebLogic Integration 10.3, you might get the following Exception during installation:

"Creating Domains...
Exception in thread "Thread-38" java.lang.OutOfMemoryError: Java heap space
at java.util.Arrays.copyOf(Arrays.java:2882)
at java.lang.AbstractStringBuilder.expandCapacity(AbstractStringBuilder.java:100)

at com.bea.plateng.domain.TemplateImporter.generate(TemplateImporter.java:340)
at com.bea.plateng.domain.script.ScriptExecutor$2.run(ScriptExecutor.java:2785)
This problem occurs when you use the 64-bit Sun JDK or 64-bit JRockit.
Workaround:
You will need to increase the heap size by doing the following:
java -Xms512m -Xmx1024m -jar wli10gR3_generic.jar

When the Medrec server goes into run mode and you try accessing the admin console for this Medrec server, you may get the following Exception:

"<Error> <netuix> <BEA-423341> <An exception was thrown while trying to map the tag [ lookAndFeel ] : [ java.lang.Throwable ].
java.lang.Throwable
at com.bea.netuix.nf.factories.TagClassMap$NamespaceTagnameMap.getClass(TagClassMap.java:189)

at com.sun.org.apache.xerces.internal.impl.XMLNSDocumentScannerImpl.scanStartElement(XMLNSDocumentScannerImpl.java:400)
Truncated. see log file for complete stacktrace
An exception can also be thrown when you try to stop the server. You get an "OutOfMemoryexception".
This problem occurs when you have the 64-bit Sun JDK installed.
Workaround:
In the setDomainEnv.sh file, increase MaxPermSize to 256. With this change, the server can start up and you can access the Admin Console without getting the above exception. The server can also shutdown gracefully.
