In the 'old days' we used to back up our clients to TSM 6.3 servers with Data Domains attached. Smaller clients backed up through the LAN, large ones through the SAN. Our newer servers use LAN-only with directory containers and the performance of these servers really sucks. Setting up a session takes sometimes almost one minute and a q stg also takes 30 to 50 seconds. I noticed that performance is OK when there are no TDP for Oracle sessions running, but as soon as they are started the performance starts to drop drastically. We are really lost on where to look for the cause. I sent numerous logs and traces to IBM, but I guess they are out of ideas too since I don't hear anything back from them lately. The only thing is that supports notices delays in DB2, but they don't know why... What I noticed on my TSM server is that as soon as there is a load on the server, the blocked queue starts to rise. I would like to know if that's something to focus on or not. Can some of you please run the "vmstat 1" command on their Linux server (preferably one with directory containers too) and let me know if you too see values other than 0 in the B column? Thank you very much for your help in advance!
