Configuration Requirements

Table 5-1 Requirements for 8.1 SP2 on HP-UX 11.0, 11i on PA-RISC

Operating System Version and Patches	HP-UX 11.0 and 11i with HP-UX patches for Java^TM, see `http://www.hp.com/products1/unix/java/patches/index.html`.
Chip Architecture and Minimum Processor Speed	PA-RISC (240 MHz) PA-RISC2.OW (650 MHz)—Supported for use with 64-bit HP-UX SDK 1.4.2.01
SDK	HP-UX SDK 1.4.1.05 with Java HotSpot^TM Server VM	WebLogic Platform 8.1 SP2 supports HP SDK 1.4.1.05 for development and production deployment on HP-UX. The HP SDK 1.4.1.05 has a limitation with respect to the character sets used by the WebLogic Platform GUI tools, such as the WebLogic Portal Content Management Administration Tools. Therefore, if you want to use the GUI tools provided with WebLogic Platform, you must install the HP-UX SDK 1.4.1.06, which is available for download from the HP Web site. For download and installation instructions, see Known Issues.
	HP-UX SDK 1.4.2.01	Supported on WebLogic Server 8.1 SP2 only at this time. For instructions on downloading and installing this SDK, see Download and Installation Instructions.
	HP-UX SDK 1.4.2.02 and all later service packs of 1.4.2	Supported on WebLogic Server 8.1 SP2 only at this time. You can download this SDK from HP at: `http://www.hp.com/products1/unix/java`
Design and Development Tools	The WebLogic Workshop IDE and WebLogic Integration Format Builder are not supported on this system. This system is supported for the production deployment of applications developed in the WebLogic Workshop IDE, and for remote debugging of applications developed in the WebLogic Workshop IDE. This system is also supported for the development and production deployment of WebLogic Server applications developed with other tools.

	Oracle 9.0.1.4	For 32-bit SDK: `lib/hpux11/oci901_8/libweblogicoci39.sl` `lib/hpux11/oci901_8/libweblogicoxa39.sl` For 64-bit SDK: `lib/hpux11/PA_RISC2.0W/oci901_8/libweblogicoci39.sl` `lib/hpux11/PA_RISC2.0W/oci901_8/libweblogicoxa39.sl`
	Oracle 9.2.0.3	For 32-bit SDK: `lib/hpux11/oci920_8/libweblogicoci39.sl` `lib/hpux11/oci920_8/libweblogicoxa39.sl` For 64-bit SDK: `lib/hpux11/PA_RISC2.0W/oci920_8/libweblogicoci39.sl` `lib/hpux11/PA_RISC2.0W/oci920_8/libweblogicoxa39.sl`

Known Issues

There is a known issue (CR128912) in the character set in HP-UX SDK 1.4.1.05 and as a result, Charset.availableCharsets() always fails. If you use this code in your applications or if you use WebLogic Portal, install HP-UX 1.4.1.06 by completing the following procedure:

Download and install HP-UX SDK 1.4.1.06 from the following HP site:

http://www.hp.com/products1/unix/java
The SDK is installed, by default, 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

There is a known issue (CR127188) with the HP HotSpot Virtual Machine that may cause a core dump when WebLogic Platform applications are run. This problem may affect some WebLogic Portal users.

The recommended workaround is to exclude the method causing the core dump. In your $JAVA_HOME/jre/lib/PA_RISC1.1/server and $JAVA_HOME/jre/lib/PA_RISC2.0/server directories, create a .hotspot_compiler file that contains the following: exclude javelin/threading/WorkItem ensureComplete

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.

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

When you use libmuxer.sl (the WebLogic Server pollmuxer), you may see an error in the log file caused by a client reset. Such an error looks similar to the following:

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

java.net.SocketException: Error in poll for fd=33, revents=at weblogic.socket.PosixSocketMuxer.processSockets(PosixSocketMuxer.java:128

This condition is harmless; you can ignore it.

Download and Installation Instructions

If you want to run the 64-bit HP-UX SDK 1.4.2.01 on HP-UX 11.0 or 11i, your configuration must be built on the PA-RISC2.OW chip architecture, including a supplemental pack for this architecture. To set up a configuration with these components, complete the following procedure:

Go to the HP Web site (www.hp.com) and download the HP-UX SDK 1.4.2.01.

Go to the BEA download site (http://commerce.bea.com) and download the following:

WebLogic Server 8.1 SP2 package installer for HP-UX 11 (PA-RISC)
Supplemental pack for HP-UX PA_RISC2.0W: wls812_hpux11PA_RISC2.0W_supp.jar

Install WebLogic Server 8.1 SP2.

Now WebLogic Server is installed. Next, install the 64-bit PA_RISC2.0W native libraries on your system, by completing steps 4-8.

Export the WL_HOME variable to point to the WebLogic Server installation:

$ export WL_HOME=/your_installation_directory/weblogic81

Go to $WL_HOME/server/lib/hpux11:

$ cd $WL_HOME/server/lib/hpux11

Extract the contents of the supplemental pack JAR file:

$ jar -xvf wls812_hpux11PA_RISC2.0W_supp.jar

Modify the environment variable SHLIB_PATH in the following shell scripts to point to the lib/hpux11/PA_RISC2.0W directory. Specifically, replace all occurrences of ${WL_HOME}/server/lib/hpux11 with ${WL_HOME}/server/lib/hpux11/PA_RISC2.0W):

${WL_HOME}/server/bin/startWLS.sh
${WL_HOME}/common/bin/commEnv.sh

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

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

Note: To execute the 64-bit SDK, you must include the -d64 option on the java command line.
