CMOD MP on AIX - Archive Server Degradation
« on: September 02, 2021, 08:12:29 AM »
Hey Gang -

Hope everyone is well!

I've run into a problem with significantly-reduced performance retrieving content from my archive server.

I'm running CMOD 9.5 on AIX with DB2 and TSM for the Archive Server.

My archive server is an AIX LPAR running 7.2.

My AIX admins tell me the box isn't even scratching the surface of memory, cpu, or swap space constraints.

My cache hits are just fine, but when routing to a storage pool pointing to my archive server, I've seen results as bad as 40 seconds or even timeouts :(

I've done some trace routing to make sure something didn't happen with routing, and that's all good.

Any quick places to look?

I'll follow with some numbers of Cache hit performance to compare with Storage Pool performance.

For a little additional information here, we're not running any DB2 stats on the archive server - running db2 10.5.

We're running arsmaint -cdemr on the library server.
