Tivoli Integrated Portal installation on AIX fails with "Failed target 'step_0000X_StartWAS'" in the installation log. The systemOut log is not created so the startup failure cause cannot be determined.
The <TIP HOME>/profiles/TIPProfile/logs/server1 directory contains only the native_stderr, native_stdout and startServer logs.
The native_stderr log shows core dump generation and "gpf" (general protection fault) references.
core and javacore files written to <TIP HOME>/profiles/TIPProfile/logs
The XPG_SUS_ENV environment variable is set to ON and prevents the execution of the JVM due to memory constraints.
Resolving the problem
unset the XPG_SUS_ENV environment variable for the install user, and then retry the installation.
