If you have a service agreement with Oracle, you can contact Oracle Support for help with JRockit JVM problems.
Before contacting Oracle Support, perform the following actions:
Try all the appropriate diagnostics and troubleshooting guidelines described in this document (Oracle JRockit Diagnostics and Troubleshooting Guide).
Check whether the problem (or a similar problem) has been discussed in the JRockit forum at http://forums.oracle.com/.
If the information available on the forum is not sufficient to help you solve the problem, post a question on the forum. Other JRockit users on the forum might respond to your question.
Collect as much relevant data as possible about the problem. For example,
If a deadlock occurs, generate a thread dump.
If a crash occurs, locate the binary crash file (where applicable) and the appropriate error file.
Document the environment and the actions performed just before you encountered the problem.
If you run the JRockit JVM in a virtualized environment, information about the type of virtualization and the software used would be useful to Oracle Support.
Where applicable, try to restore the original state of the system and reproduce the problem using the documented steps. This helps to determine whether the problem is reproducible or an intermittent issue.
If the issue can be reproduced, try to narrow down the steps for reproducing the problem. Problems that can be reproduced by small test cases are typically easier to diagnose when compared with large test cases.
Narrowing down the steps for reproducing problems enables Oracle Support to provide solutions for potential problems faster.
Note:
When you send files (.dump, .core, and so on) to Oracle Support, remember to provide the MD5 checksum value for each file, so that Oracle Support personnel can verify the integrity of the files before using them for troubleshooting the problem.
