BEA jDrivers for Oracle	Oracle 9.2.0.5	`lib/hpux11/IPF32/oci920_8/libweblogicoci39.so` `lib/hpux11/IPF32/oci920_8/libweblogicoxa39.so`

Known Issues

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.

The Smart Update facility cannot be used to upgrade your WebLogic Platform software from a pre-SP5 version to SP5 on an HP-UX 11i V2 on Itanium configuration. If you want to upgrade your existing WebLogic Platform 8.1 software to SP5, use the upgrade installer, instead.

This issue is being tracked in CR212708. For more information, see the description of CR212708 in the WebLogic Platform 8.1 Release Notes: http://download.oracle.com/docs/cd/E13196_01/platform/docs81/relnotes/relnotes.html#cr212708

The WebLogic Platform upgrade installer (pj_platform815_upgrade_generic.jar) cannot be used to perform upgrades:

From 8.1 SP4 to 8.1 SP5
From 8.1 SP3 to 8.1 SP5
From 8.1 SP2 to 8.1 SP5

If you try to perform one of these types of upgrade with the upgrade installer, a java.lang.OutOfMemory exception is thrown. You may need to increase the size of the thread stack with the -Xms and -Xmx options, as follows: java -Xms512m -Xmx512m -jar pj_platform815_upgrade_generic.jar

For more information about known issues with any components of this release, see the appropriate Release Notes document. For a complete list of Release Notes supporting WebLogic Platform 8.1, see:

Download and Installation Instructions

Installing and using WebLogic Platform 8.1 SP5 on HP-UX 11i V2 (11.23) on Itanium requires the following:

HP-UX SDK 1.4.2.08 for Itanium
WebLogic Platform 8.1 SP5 package installer for HP-UX 11i V2 (HP-UX 11.23)

To install WebLogic Platform 8.1 SP5 on HP-UX 11i V2 (HP-UX 11.23), complete the following procedure:

Go to the following HP Web site:

http://www.hp.com/products1/unix/java/java2/sdkrte14/downloads/license_sdk_1.4.2.08_itanium.html
Download and install HP-UX SDK 1.4.2.08.

Go to the BEA Downloads site (http://commerce.bea.com) and download the appropriate package installer:

For WebLogic Platform: pj_platform815_generic.jar
For WebLogic Server: pj_server815_generic.jar

Install WebLogic Platform 8.1 SP5 or WebLogic Server 8.1 SP5 for HP-UX 11i V2 using the instructions provided for .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_platform815_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_platform815_ja_generic.jar -mode=console

Set the WL_HOME variable to the directory in which you installed WebLogic Platform, and export WL_HOME:

$ export WL_HOME=/your_installation_directory/weblogic81

Set the correct execution modes on the contents of the weblogic81/server/bin and weblogic81/server/lib directories:

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

Recommended Kernel Parameter Settings

The HP-UX 11i V2 (11.23) default value for maximum threads per process (max_thread_proc) is 64, which may be too low for WebLogic Server and many Java server applications in general. When the value is too low, WebLogic Server may have problems starting up. Therefore BEA recommends that you use the maximum kernel setting for the max_thread_proc parameter.

The following table provides some examples.

Table 3-2 Recommended HP-UX 11i V2 (11.23) Kernel Settings

Parameter	Old Value	New Value	Decsription
`max_thread_proc`	`64`	`3000`	Maximum threads per process
`Maxdsiz_64bit`	`1073741824`	`4294967296`	Maximum data segment size
`maxfiles`	`60`	`2048`	Soft file limit per process
`nkthread`	`499`	`8416`	Total number of threads in the system
`nproc`	`276`	`4200`	Maximum number of processes

BEA also recommends that you use tools such as HPjconfig to verify that the values of your tunable kernel parameters are optimal. For more information about HPjconfig, see:
