Muthyam, Lotza things you could look at:
DSM.SYS file check the parmaters, do they make sense or jive with your OS settings? Check the archives for TSM to OS tuning, I've caught a lot of good articles there! Is compression on? Lotz of work on the client to do that. What is your backbone? GBit/Css/En ? Is your API current? What DB2 level are you at, there was a bug back a year or so ago with DB2 not working correctly with TSM. Is your TSM server a utility server like ours running 60+ billion other applications, gasping for memory begging to turn itself off? We had a slowness or "it won't do" performance problem. We took 3 hours off our backups changing mgmt class to go to tape. Also running 1/2 on SP switch and 1/2 on GBit.(Switch card was getting hammered) I get about 25 Sessions/Clients done in 15-16 hours for 12TB. 12 Fcal Tape drives(3590). Client wants it done in 8. All I want for xmas is a NEW TSM server. :) --- Muthyam Reddy <[EMAIL PROTECTED]> wrote: > ** High Priority ** > > Hello...one and all > subject:Slow DB2 backups on TSM. > > We have recently migrated our database to DB2 from Infromix on AIX 4.3 and TSM > version level 5.1.0.0. > Before migration..
