Error in executing OWBClient.sh in UNIX - unix

Question

I am trying to run the OWBClient.sh with the command in UNIX and I am getting the following error:
" The JVM option is invalid: -XX: MaxPermSize=256M. Could not create the Java Virtual Machine."
OWB Version: 10.2.0.5
Oracle Database : 10g
UName: AIX
When exploring more on the above issue, I got an information that OWB 10.2 could not be run in AIX. It would be helpful if anyone can can shed some light on whether OWB 10.2.0.5 can be run on AIX?
Editing my post to share an update.I have tried to execute the owbclient.sh file by removing the -XX:MaxPermSize=256M part. I am now getting a different kind of error...
$ ./owbclient.sh
