Portal Server can't be started on Linux Redhat

[gige...@yahoo.co.uk]

I can start again the Portal on a Redhat version. The issue is similar to that posted in an earlier post, but this time it relates to an Redhat OS. I have installed correctly the system that has been working fine. However, when I restarted the server and I tried to restart both the Application Server and Portal Server with the correct shell commands I was never successful and I always get an error. This is the content SystemOut.log. Can anyone help me in such a issue? Thanks:
