I'm having trouble configuring WAS4 (advanced single server edition) to run as a non-root user on my RedHat 7.3. I found a guide from IBM, which was supposed to tell me how to do this, but the result of following the guide was an ambiguous "Operation not permitted". Would someone out there happen to have a sort of checklist for what could be missing? I've chown'ed the whole ../../WebSphere directory recursively to the user I'm planning to use. The startServer.sh script starts but shortly aborts (after about 10 lines of log messages) with "operation not permitted". Any help is much appreciated. Thank you.
