IBM Tivoli Composite Application Manager for Application Diagnostics, Version 126.96.36.199
Scenario 1: Pinpointing problems
Application A's response time slows to unusable when the server experiences even moderate throughput, while resident time is idle. Using SMF data, view the percentage of threads used in the Database Connection Pools, Thread Pools, and JCA Connection Pools; this will tell you if there is a bottleneck in the application server pools. Any pool that is at or near 100% is most likely being overwhelmed by application A's requests for those resources. To fix the problem, you can create more or larger pools.
