50-150 connections seems to be quite a low value. I’d guess that for each client connection there should also be one DB2 connection, plus a few. During the housekeeping window: one for each expiration thread, one for each reclaim or migration process, etc. SO tens of DB2 connections on a large server should be normal, hundreds during peak back-up window, I’d guess. > Yes, I could easily just look at my existing trends and derive them, but I > was hoping to gain insight into what is actually going on that so many > connections are necessary. > > Thanks for your time > > Best regards, > > Mike Ryder > RMD IT Client Services -- Met vriendelijke groeten/Kind Regards, Remco Post r.p...@plcs.nl +31 6 248 21 622
