Known Issues

Issue

Description

Workaround

IIOP Thin Client not supported

The IIOP Thin Client is not supported on Red Hat Enterprise Linux on IBM pSeries configurations due to dependencies on the JVM. Only thin-client applications are affected by this issue.

Run WebLogic Server on Red Hat Enterprise Linux on IBM pSeries configurations, and your Thin Client on another operating system.

Language setting limitation

The JSP files of WebLogic Server sample applications are encoded in ISO8859-1, but the default encoding on Red Hat Enterprise Linux on IBM pSeries configurations is UTF-8. This difference causes errors when JSP files are parsed.

Set the environment variable `LANG` to en_US.ISO8859-1 by entering the following command:
`export LANG=en_US.ISO8859-1`

`wlkeytool` not supported

`wlkeytool` is not supported on Red Hat Enterprise Linux 4.0 on IBM pSeries (64-bit environment).

None

Download and Installation Instructions

This section provides instructions for the following procedures:

Downloading and Installing IBM 64-bit SDK 1.4.2

Go to the following IBM download site:

https://www14.software.ibm.com/webapp/iwm/web/reg/pick.do?source=lxdk

The download page is displayed.

Select "IBM SDK for 64-bit iSeries/pSeries, Version 142 SR1a-2."

Follow the instructions displayed to download the SDK in tgz format and install it. For example:

tar xzf IBMJava2-SDK-142.ppc64.tgz

Set the JAVA_HOME environment variable to the directory in which IBM SDK 1.4.2 SR1a+ is installed, and export JAVA_HOME. For example:

export JAVA_HOME=/opt/IBMJava2-ppc64-142

Make sure that your PATH variable includes $JAVA_HOME/bin. For example:

export PATH=$JAVA_HOME/bin:$PATH

To verify that the required SDK fixes are now installed on your system, run the following command:

java -version

Make sure the output contains the following string: Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2) Classic VM (build 1.4.2, J2RE 1.4.2 IBM build cxp64142sr1aifx-20050427 (142SR1a + 82052 + 85266) (JIT enabled: jitc))

Downloading and Installing WebLogic Server 8.1 SP4 and Supplemental JAR File

To download and install WebLogic Server 8.1 SP4, complete the following procedure:

Go to the BEA downloads site:

http://commerce.bea.com/index.jsp

Download the following items:

WebLogic Server 8.1 SP4 installer for Red Hat Enterprise Linux 4.0 for IBM pSeries: pj_server814_generic.jar
Supplemental JAR file for WebLogic Server 8.1 SP4: wls81sp4_plinux64_supp.jar

Install WebLogic Server 8.1 SP4 by running the following command in console mode:

$ java -Dos.name=plinux -jar pj_server814_generic.jar -mode=console

For a detailed console-mode procedure for installing JAR files, see Installing BEA WebLogic Platform: http://download.oracle.com/docs/cd/E13196_01/platform/docs81/install/index.html.

Unjar the wls81sp4_plinux64_supp.jar file to the new directory. For example, if you have saved wls81sp4_plinux64_supp.jar in a directory called /tmp, enter the following commands to unjar the supplemental file:

$ export WL_HOME=/your_installation_directory/weblogic81; $ cd $WL_HOME/server/lib/linux; $ jar -xvf /tmp/wls81sp4_plinux64_supp.jar;

Add execute permission to the files in weblogic81/server/bin and weblogic81/server/lib:

$chmod +x $WL_HOME/server/bin/*
$chmod -R +x $WL_HOME/server/lib/linux/ppc64/*
