Known Issues

Known Issues Pertaining to HP-UX JDK

If you are using releases of HP-UX JDK 5.0.04, HP-UX JDK 5.0.05, and HP-UX JDK 5.0.06, you may experience an out-of-memory error. Oracle recommends upgrading to the latest JDK version. See http://www.hp.com/go/java.

Increase MaxPermSize

You may need to increase the MaxPermSize parameter based on application requirements. For example: For the WebLogic Portal Groupspace sample, you may need to increase the MaxPermSize from 128MB to 256MB.

Serial Version UID Mismatch

A Serial Version UID Mismatch Issue is encountered if you deploy an application on a latest JVM, but built with Sun JDK 1.5.0_06 or HP JDK 1.5.0.4 equivalent

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 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.

Unable to Start WebLogic Server While Logged in as root

If you start or install WebLogic Server while logged in as root, while using the JDK, the server may fail to start and throw a java.security.ProviderException. If this happens, complete the following procedure:

In a text editor, open the java.security file in the directory JAVA_HOME/jre/lib/security, where JAVA_HOME represents your JDK installation directory.
Find the securerandom.source=file:/dev/urandom entry. Change it to:

securerandom.source=file:/dev/random

Save the java.security file with your changes and close it.
While still logged in as root, restart WebLogic Server.

Recommended Kernel Parameter Settings

• Oracle recommends that you set the maxdsiz kernel parameter to a minimum value of 2 GB.
• On HP-UX 11 systems, the default value for maximum threads per process is 64. This value may be too low for WebLogic Server and many Java server applications: WebLogic Server may have problems starting up. Therefore, Oracle recommends that you use the maximum kernel setting for the max_thread_proc parameter: 1024.
• Oracle recommends that you set all the parameters to the values shown in the following table.

Parameter	Recommended Value	Description
max_thread_proc	1024	Maximum threads per process
maxfiles	256	Soft file limit per process
nkthread	3635	Number of threads total on the system
nproc	2068	Maximum number of processes
