Monitoring Fast Path systems
The major emphasis for monitoring IMS online systems that include message-driven Fast Path applications is the balance between rapid response and high transaction rates.
With Fast Path, performance data is made part of the system log information. Because the bulk of the online traffic is expected to be handled by expedited message handling and not be present on the message queues, the Fast Path Log Analysis utility (DBFULTA0) is the prime tool for monitoring Fast Path applications. The IMS Monitor can also be used to monitor Fast Path systems.
- A detailed listing of exception transactions
- A summary of exception detail by transaction code for MPP (message-processing program) regions
- A summary by transaction code for MPP regions
- A summary of IFP, BMP, and CCTL transactions by PSB name or transaction code
- A summary of the log analysis
Do not confuse this utility with the IMS Monitor or the IMS Log Transaction Analysis utility.
As an administrator in the Fast Path environment, you should perform tasks, like establishing monitoring strategies, performance profiles, and analysis procedures. This topic highlights how to use the Analysis utility to do these tasks, and suggests some Areas where tuning activities might be valuable.
