Known Issues

• The HP-UX 11.0 default value for maximum threads per process 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.

BEA recommends that you use the maximum kernel setting for the max_thread_proc and maxusers parameters. Setting maxusers to a higher value increases other machine-wide limits, such as nkthread (the maximum number of kernel threads). The following table provides some examples.

Table 7-2 Recommended HP-UX 11.0 Kernel Settings

Parameter	Old Value	New Value	Description
max_thread_proc	64	1024	Maximum threads per process
maxfiles	60	256	Soft file limit per process
maxusers	32	256	Influences other parameters
nkthread	499	3635	Number of threads total on the system
nproc	276	2068	Maximum number of processes
ncallout	292	2084	Number of pending timeouts


 

• The setuid function does not work. This problem is a known issue with HP-UX SDK 1.4.1.05. HP is working to resolve it.
• There is a known issue with the character set API in HP-UX SDK 1.4.1.05. As a result, Charset.availableCharsets() always fails. If you plan to use this code in your applications, install HP-UX 1.4.1.06, as follows:
Download HP-UX SDK 1.4.1.06 from the following HP site:

http://www.hp.com/products1/unix/java

Install the 1.4.1.06 SDK on your system. By default, it is installed in the following directory:

/opt/java1.4

Rename the original SDK:

mv $BEA_HOME/jdk141_05 $BEA_HOME/jdk141_05.orig

Create a symbolic link to the new SDK:

ln -s /opt/java1.4 $BEA_HOME/jdk141_05

For more information about known issues with any components of this release, see the Release Notes document for WebLogic Server, available at:

Download and Installation Instructions

This section provides instructions for the following tasks:

• Downloading and Installing the HP-UX SDK 1.4.1.05
• Downloading and Installing WebLogic Server 8.1 SP1

Downloading and Installing the HP-UX SDK 1.4.1.05

Download the HP-UX SDK 1.4.1.05 from http://www.hp.com.
Install the JDK in your environment and then make the following changes in your environment:
• Update the JAVA_HOME environment variable to reflect the JDK installation directory. For example: JAVA_HOME=/opt/java1.4; export JAVA_HOME
• Update the PATH environment variable to include JAVA_HOME/bin. For example: PATH=$JAVA_HOME/bin:$PATH; export PATH

Note: There is a known issue with the character set API in HP-UX SDK 1.4.1.05. As a result, Charset.availableCharsets() always fails. If you plan to use this code in your applications, install HP-UX 1.4.1.06, as described in Known Issues.

Downloading and Installing WebLogic Server 8.1 SP1

Go to the BEA Downloads site (http://commerce.bea.com) and download the following:
• WebLogic Platform installer: pj_server811_generic.jar
• HP-UX 11i V2 on Itanium supplementary JAR file: wls811_hpux1123_supp.jar

Note: This file contains supplementary installation and configuration files for HP-UX 11i V2 on Itanium.

Install WebLogic Server 8.1 SP1 by completing the the console-mode installation procedure for .jar files in Installing BEA WebLogic Platform at http://download.oracle.com/docs/cd/E13196_01/platform/docs81/install/console.html:

$ java -jar pj_server811_generic.jar -mode=console

Set the WL_HOME variable to point to the WebLogic Server installation, and export WL_HOME:

$ export WL_HOME=/your_installation_directory/weblogic81

Add weblogic81/server/bin to your execution path:

$ export PATH=$WL_HOME/server/bin:$PATH

Go to $WL_HOME/server/lib/hpux11:

$ cd $WL_HOME/server/lib/hpux11

Extract the contents of the wls811_hpux1123_supp.jar file:

$ jar -xvf wls811_hpux1123_supp.jar

This step creates new directories for native libraries.

Update the environment variable SHLIB_PATH in the following shell scripts:
• $WL_HOME/server/bin/startWLS.sh
• $WL_HOME/common/bin/commEnv.sh

Replace all occurrences of $WL_HOME/server/lib/hpux11 with $WL_HOME/server/lib/hpux11/IPF32.

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/*
