Re: Excessive Paging in TRU64
Recently, I have noticed that there is lot of paging happening in my system. We have 2 COMPAQ Alpha ES40, each with 2 CPUs and 2 GB RAM and a COMPAQ RA8000 to support.
I am attaching herewith the sys_check output of both servers.
Please help urgently.
Thanks & Regards,
Trupti.

Re: Re: Excessive Paging in TRU64
you should first try to find out which processes are using the memory, f. e. with use of "ps vax" command. The VSZ column shows you the virtual size of the process, more interesting is the RSS column, which shows you the resident size of memory the process is using. "ipcs -ma" tells you about shared memory used.

Re: Re: Excessive Paging in TRU64
With "vmstat" you will see the paging activity, the column "pout" shows the no. of pages paged out to swap per invervall (ignore the first line of vmstat output, it is the sum since system boot). The column "memory free" shows the number of free pages (should be commonly above 128k).
I don't believe once can solve your problem by this forum in time, performance tuning is a complex job, you should involve your application provider or one of our help centers (hotline).
