In addition to helping customers resolve issues via Service Requests, Oracle Support also builds over 60 free diagnostic tools for Oracle E-Business Suite 12.2, 12.0, 12.1, and 11i. These Support Analyzers are non-invasive scripts that run health-checks on your EBS environments. They look for common issues and generate standardized reports summarizing that provide solutions for known issues and recommendations on best practices.
Here's an index to these tools:
Spotlight on Concurrent Processing Analyzer
I recently profiled the Workflow Analyzer. In addition to that tool, I'd recommend taking a look at the Concurrent Processing Analyzer:
The Concurrent Processing Analyzer reviews CP configurations and compares them against Oracle's best practices.
This tool can be run manually or configured to run as a concurrent request, so it can be scheduled to be run periodically and included in regular Workflow Maintenance cycles.
Can this script be run against Production?
Yes. There is no DML in the Analyzer Script, so it is safe to run against Production instances to get an analysis of the environment for a specific instance. As always it is recommended to test all suggestions against a TEST instance before applying to Production.
