Failure during patch installation on IBM InfoSphere Information Server 8.1 running on Aix

Problem

Installation of patch fails on IBM InfoSphere Information Server 8.1 running on Aix, due to the fact that the patch installer fails to restart IBM WebSphere

Symptom

Unable to install patch, as IBM WebSphere fails to start and produces a Core Dump

Cause

Trouble building LIBPATH due to the length of the environment variable

Resolving the problem

1. Create the file MetadataServer_env.sh in the <IS_HOME>/ASBServer/bin directory, with the following entries:
#!/bin/sh
unset LIBPATH
unset LDR_CNTRL
export LIBPATH LDR_CNTRL

NOTE: LDR_CNTRL is also being unset as IBM Information Server 8.1 is a 64-bit application.

LDR_CNTRL should not be set for 64-bit programs, as this will limit the amount of memory a 64-bit program can use. This variable is intended primarily for 32-bit programs.

2. Set permission on the file:

chmod 775 MetadataServer_env.sh

If the file is already there then ensure that the above entries as per Point 1 are added. This file will then be sourced by the patch installer when it restarts IBM WebSphere during the patch installation.
