Tariq Farooq

During the presentation a clear explanation if given of the Database performance process using Oracle Enterprise Manager Grid Control. Showing several examples from the Database Performance Tab and showing the advantage of several linked features like Top Activity, Blocking Sessions.

The presentation next focuses on the three A’s for Database Performance Tuning:

  • ASH  (Activity Summery History)
  • AWR (Activity Workload Repository)
  • ADDM (Automatic Data Diagnostic Monitoring)

Realizing AWR is the successor of the former statspack feature, several examples are given of how to interpret some of the output.

I think a very good and solid presentation, focusing merely on novice users of which there are a lot in the OEM GC arena.

During the installation of OEM GC 11.1 on AIX, there was no auto discovery of the Middleware Components

While doing the installation of OEM GC 11.1 on AIX 6.1, I noticed that there was no automatic discovery of the Middleware targets.

This is due to bug 9969664.

The solution provided in MOS Note:

Error when discovering and monitoring secured weblogic domains on AIX platforms (using t3s/iiops protocols) in EMGC11.1 (Doc ID 1208874.1)

did the trick for me and discovered the 8 additional Middleware targets.
