Helpful Hints For Obtaining Technical Assistance:
Before contacting IBM Automatic Binary Optimizer for z/OS Support, gather the background information that you need to describe the problem. When you describe a problem to an IBM software support specialist, be as specific as possible and include all relevant background information so that the specialist can help you solve the problem efficiently. To save time, know the answers to these questions:
- Can you reproduce the problem? If so, what steps and compiler options do you use to reproduce it?
- Can the issue be reduced to a small test case?
- Can the test case be provided to IBM?
- What compiler version and fix pack level were you using when the problem occurred?
- Do you have logs, traces, or messages that are related to the problem?
- Is there a workaround for the problem? If so, be prepared to describe the workaround.
The FAQ for IBM Automatic Binary Optimizer for z/OS has a list of the most frequently asked ABO usage or maintenance-related questions and their answers.
There is a Mustgather document that describes what supporting documentation to collect in order to help the IBM Automatic Binary Optimizer Support Team diagnose your problem.
If you have helpful information to diagnose or identify the problem on your system, you can provide this data by following the instructions to exchange information with IBM Technical Support .
