We are running a K460 with HP-UX 10.20 and Oracle 8.0.5.
Through "sarcheck" it is showing that there may be some memory leakage in some programs.
Do you know is there any tools/scripts to find out the memory leakage?
thanks in advance.

Re: Tools/scripts to find out Memory Leakage
look at Purify and Insure++
Buyer beware, things can get tricky when your either
testing an .sl that loaded with something like Oracle Application Server
or
your using code (executable or .sl) that depends on someone else's code (e.g. Oracle) and the leak is in someone elses code.
Both of these tools require you to be able to instrument your code (i.e. compile and link against special libraries).

SolutionSo you need to track down the programs that are growing in size. There's nothing magic, just a lot of record keeping. Start by sorting all your processes by memory size:
# UNIX95= ps -eo "vsz,pid,ruser,args" | sort -rn
Then have cron run this command line every 5-10 minutes, directed into a file and look for trends as the sizes get larger. NOTE: The application may have been designed to work in that manner so verify with the authors that this is expected behavior.
