Unable to start Sybase after extending /va
I've been experiencing some issues starting up Sybase in HP-UX 11i v3 Superdome server. It has been working fine until I extended my /var from 5GB to 8GB. Since I didn't have OnlineJFS to do it, I went into single user mode to extend my /var.
I was able to extend it successfully and booted up my machine to normal mode. There are two noticeable weird things occured after bootup.
1. Most of the sybase owned related files changed its permission from "sybase:sybase" to "sybase:106"
2. I can no longer start-up my Sybase database and have the following error:
$ startserver -f RUN_CCBDB_SDS

I already changed the permissions of all sybase related files back to "sybase:sybase" but this very same error occurs each and every time I am attempting to startup my Sybase database.
I dont know why all of a sudden that my Sybae database can't get a hold of the memory it needs to start since it can previously.
I am also not sure how extending a /var filesystem would affect it.
I have basically done my research. Some are suggesting that I should edit my /etc/setprivgrp file and set the privelege for sybase. However prior to my miseries I was able to startup sybase without this file being configured.
Currently here's the swapinfo output from my server

Re: Unable to start Sybase after extending /va
How much RAM do you have in this server?
Have you changed the amount that Sybase is trying to allocate? According to this message:
kernel os_create_region: can't allocate 32275791872 bytes
You are trying to allocate 32 GB. Do you have enough free RAM for that?
