Abend error recording by problem determination routines

When a determinate error arises during O/C/EOV processing or during open or close access method executor processing, the problem determination routines gather data related to the abnormal termination condition and related information, and then issue the GTRACE macro to pass the information to GTF. After issuing the GTRACE macro, the O/C/EOV routines issue the abend macro instruction to pass control to the R/TM. The information passed to GTF will also appear in the abend dump and will be written to the GTF data set. Examples of GTF output appears in Figure 1 and Figure 1.

This GTF output resulted from a 213 system completion code with a return code of X'04', meaning that the format-1 DSCB for the data set to be opened could not be found.

The problem determination routines write the data set name from the JFCB into the GTF data set.
