Diagnosing Fast Path problems

Before diagnosing problems in Fast Path, you must understand the structure of its dumps, especially the dependent region dumps.

When a dependent region abends, the structure of the dump varies, depending on a number of conditions. For example, if you requested and were able to perform offline dump formatting, the structure of the dump is different than if you had not requested offline dump formatting. Furthermore, if the dependent region that abends is an MPP executing in mixed mode, the structure of the dump might be different from that of an IFP region. The recommended approach is to request and use the offline dump formatting option.
