Hi: all
I have one oracle test enviorment that run on hp-ux 11.00 platform.
When I execute some operation like delete million rows from one table ,
the free memory of OS reduce qucikly.
But when the operation finished, the memory occupied by the delete process not return to OS.
I think maybe some patch related to process memory leak that I have not install.
Some one told me that I need install patch phss_23655 .
Can you tell me some other patch must installed on hp-ux 11.00 ? Thanks !!

Very, very often when "...process not return to OS..." this is because the process has become a runaway. Can you stop oracle?

Try fuser /filesystem

-or-

ps -ef | grep -i ora

-or-

lsof /filesystem

...and analyze.

It has been my experience that the best resolution to a memory leak problem...has been to find the process, and fix it's code.

Just a thought,
