Known Issues

This section provides:

• Known Issues Pertaining to HP-UX JDK
• Issues with HP-UX 11i v2 on Itanium
• Serial Version UID Mismatch
• Increase MaxPermSize
• Known Issues for Other Products

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.

Issues with HP-UX 11i v2 on Itanium

• If your application involves working with very large objects via RMI over IIOP, then it may encounter the following exception:

java.rmi.MarshalException: ; nested exception is: org.omg.CORBA.MARSHAL: vmcid: 0x0 minor code: 0 completed: 

If you see this exception, you may need to increase the size of the thread stack with the -Xss option. The JVM default is 512 KB; the new value depends on the size of the object in question.

• If, during installation, you get an OutOfMemory error message, you need to increase the maximum heap size by specifying the -Xmx argument on the command line. For example:

$ java -Xmx512m -jar alsb200_wls900_generic.jar -mode=console 

• When WebLogic Server domains are being created or upgraded in console mode on an HP-UX 11i v2 on Itanium configuration, the window titled "Configure JDBC Data Sources" is not displayed properly. To create or upgrade a WebLogic Server domain on this configuration, use GUI mode or silent mode (with scripts).
• If you start WebLogic Server while logged in as root, while using the JDK 5.0.01, 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 5.0.01 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.

Serial Version UID Mismatch

A serial version UID mismatch is encountered when using WebLogic Server with HP-UX Java 5 (JDK 1.5.0.03 and higher).

Workaround: To be compatible with the serialization of previously compiled applications, modify the <BEA_HOME>/Weblogic90/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.

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.

Known Issues for Other Products

For more information about known issues with products supported on this configuration, including available workarounds, see the appropriate Release Notes document.

Download and Installation Instructions

Note: These instructions are provided only for customers running HP-UX 11i v2 on Itanium. If you are running HP-UX 11i v2 on PA-RISC, you can simply follow the instructions in Products Installation Guide, available at http://download.oracle.com/docs/cd/E13179_01/common/docs90/install/index.html.

To run your products on HP-UX 11i v2 on Itanium, your configuration must include the following components:

• HP-UX JDK 5.0.01 for Itanium
• WebLogic Server 9.0 or AquaLogic Service Bus 2.0 package installer for HP-UX 11i v2

To obtain these components and install your products, complete the following procedure:

Go to the following HP Web site:

http://www.hp.com/products1/unix/java/java2/jdkjre5_0/downloads/license_jre_5.0.01_itanium.html

Download and install HP-UX JDK 5.0.01.

Go to Oracle Technology Network or Oracle E-Delivery and download WebLogic components for HP-UX.

Note: For important information on how to download BEA products refer to My Oracle Support Note 762254.1 and My Oracle Support Note 763603.1.

Note: The BEA Download Center (i.e. http://commerce.bea.com) will be decommissioned on February 2, 2009. After this time, customers will be able to download the BEA software from Oracle's E-delivery portal (http://edelivery.oracle.com) or Oracle Technology Network (http://otn.oracle.com).

Install WebLogic Server 9.0 or AquaLogic Service Bus 2.0 on your HP-UX 11i v2 configuration by completing the console-mode installation procedure for .jar files available at:

http://download.oracle.com/docs/cd/E13179_01/common/docs90/install/start.html

Set the WL_HOME variable to the directory in which you installed your product, and export WL_HOME. For example:

$ export WL_HOME=/your_installation_directory/weblogic90

In ${WL_HOME}/common/bin/commEnv.sh, modify the value of the SHLIB_PATH environment variable so it points to the IPF32 directory (instead of the PA_RISC directory) under server/native/hpux11. In other words, replace all occurrences of PA_RISC with IPF32 in the ${WL_HOME}/common/bin/commEnv.sh shell script.
Set the following execution modes on the contents of the weblogic90/server/bin and weblogic90/server/native directories:

$ chmod +x $WL_HOME/server/bin/*
$ chmod -R +x $WL_HOME/server/native/hpux11/*

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
