Does anyone know why, we have recently upgraded to 8.9 and now our 3 Tier Client is causing problems....DB2 temp space fills up quickly to the max, PSVERSION table is locking, both resulting in app server queuing, web server queuing and just general slow response for online PIA users. Has anyone experinced this or have any ideas on what could be happening? Also I have noticed scopes disconnecting half-way through rport runs.
