Delete comment from: Java EE Support Patterns
Thanks John for your comments and very good question,
Just to you and my other readers an idea of the effort...
The root cause analysis and code walk-through was performed by myself for my IT client:
- 1 week elapsed time for JVM heap dump generation prep work, risk mitigation, planning etc.
- 4 hours for Heap Dump generation process via jmap
- 2-3 hours Heap Dump analysis via MAT tool
- 1 day of JPA / OpenJPA specs + doc review + code walkthrough
- 2 days of code resolution (implemented by the delivery team)
You can expect a longer RCA process for individuals with minimal exposure with this type of troubleshooting.
I'm planning to release in the future articles comparing the MAT analysis route vs. tool like Plumbr via our crash test application.
More to come...
Regards,
P-H
