Version 126.96.36.1994 of Mumbai is available for download. Here’s the list of changes:
- Added ASH data viewer (supports ASH and BASH data)
- Added one-click 10046 tracing for scripts in the console window
- Lots of small tweaks and fixes
After releasing the BASH package that makes active session history data available without a Diagnostic Pack license, an ASH data viewer in Mumbai was the logical next step.
The layout as shown below is similar to what you might know from the ASH data shown in Enterprise Manager/Cloud Control/DB Console or from ASH Viewer, but there are, in (more...)

Presenting at DOAG 2011 was a great experience, so I am very happy to present again at DOAG 2012. The title of the session is “Analysis and Visualizing Statspack and AWR data” (it will be in german language though).
Here’s the abstract:
Der Referent gibt eine Überblick über Statspack und Automatic Workload Repository (AWR), erläutert die Konzepte um die meist großen Mengen von vorhandenen Statspack/AWR Daten zu analysieren und führt in Demos vor, wie diese Konzepte in "Mumbai", einem frei-verfügbaren Windowsprogramm u.a. zur Oracle Performanceanalyse, implementiert wurden.
Der Referent zeigt die Probleme der Durchschnittsbildung, die Grenzen der Statspack/AWR Daten (more...)
