Convergence activities� Merge the best of both the DB2 PM/PE and OMEGAMON X E DB2

product offerings into a new offering

�

Simply spoken, we’ve combined the DB2 PM/PE reporting and performance warehouse functions with the real-time monitoring strength and integrated OMEGAMON end user capabilities (XE and Classic VTAM)

� Merge functions of both data collectors into one

�

Reduce footprint and system resources

� Provide new unique functions to both former custome r sets

� The “Performance Expert“ is a combination of the Per formance Monitor and the DB2 Buffer Pool Analyzer, plus addi tional “expert” functions, i.e. ROT (Rules of Thumb) and ex pert SQL queries.

DB2 Connect Monitoring – The different views

1. Show all connections on a DB2 Connect (gateway)

2. Show DB2 Connect specific data for a selected DBAT thread

3. Show all connection to the selected DB2 Subsystem from different DB2 Connect (gateways)

All three views allow zoom into more details.

Performance data from DB2 Connect can be shown from different perspectives:By monitoring the DB2 Connect itself or drilling do wn into thread and database statistics.
