Hi,

Did you try my suggestion?

If you are having performance problems, then it may be that your environment requires a reevaluation.  I doubt your issue is AIX unless the server is multi-purposed and not just a dedicated TSM server.

There are many ways to look at your systems performance; you can use topas/nmon to see what the system is doing in terms of resources being used i.e. disk i/o, memory stats, active processes etc.

For TSM performance you can enable tracing using the admin console (dsmadmc) to see what is occurring and potentially capture the moments prior to failure.

Are you able to query the TSM activity log using the admin console? This may only give you what you already know however.

Cheers, JP.

Hi

Try running the dsmserv to see if you can capture the failure. If you see:

Insufficient memory to open receiver stream

Then this problem can be resolved by placing the following in the dsmserv.opt;

LANGUAGE en_US

and run up your server process again.

Cheers, JP

Hello JP,


ANS1474E is the only error message that i found, i think issue is on aix,  because TSMis very slow so must be a lot of process running at the same time but i dont know how confirm that or check more details in TSM about issue.
