Profiling agent libraries are not loaded on the AIX platform

I have never received this error before. Why am I getting this error and how can I fix it?

Symptoms

Profiling agent libraries are not loaded.

Resolving the problem

Run export LIBPATH=$LIBPATH:$TOP/profiler/jprofiler before you start the appserver and enable profiling for any services. The LIBPATH environment variable must be exported in the same shell prompt that you use to start the appserver or enable profiling for any services.
