| I'm using the connection concentrator with db2 v8.2 on AIX 52 with this configuration: max_connections = 4000 maxagents = max_coordagents = num_poolagents = 600 num_initagents = 100 maxcagents = max_coordagents intra_parallel = yes, but default degree is 1 the average number of applications connected to the database is about 1500. these applications do very short transactions and many file transfer so that most of the time they are decoupled. the only problem I noticed is that the 3 db2disp processes allocates use more or less one cpu each... Power4+ 1.1 Ghz (regatta, p690). another info is the number of "agent stolen from other applications" that is about 150~200 per second. is there any doc or suggestion I can use to understand how to limit the CPU usage, or a better configuration? thanks in advance, marco --- Marco Negri, I.NET s.p.a +39 02 32863 ext 1 |
