Analyzing component trace

The output from component trace will allow you to find the module ID of the failing module and to identify parameters that are passed to the module. Trace will produce output in the format shown in Figure 1.

Figure 1. Example: Component trace output

Each ctrace entry is consistent up through the module IDs. After that, each entry has its own format. To identify the fields:

Find the halfword module identifier in IXGXMT. This will identify the module name.
Browse the module to find the full id, which will identify the label in that module where the trace record was requested.
