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).
For more information about known issues with this release, see WebLogic Server and WebLogic Express Release Notes:
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:
