Subsystem and Transaction Monitoring and Tuning with DB2 11 for z/OS
Understand the DB2 traces
Monitor and tune the DB2 subsystem
Monitor and tune the DB2 transactions
This IBM Redbooks publication discusses in detail the facilities of DB2 for z/OS, which allow complete monitoring of a DB2 environment. It focuses on the use of the DB2 instrumentation facility component (IFC) to provide monitoring of DB2 data and events and includes suggestions for related tuning.
We discuss the collection of statistics for the verification of performance of the various components of the DB2 system and accounting for tracking the behavior of the applications.
We have intentionally omitted considerations for query optimization; they are worth a separate ...
