Missing VTAM trace records
- Problem statement
- The expected output data is missing from a VTAM® trace that was run with GTF active.
- Common symptoms
- There is no VTAM data, missing VTAM data, or unwanted data in the GTF trace data set.
- Probable cause
- When TRACE=USR is specified, GTF collects all USR events issued in the MVS™ system.
- User response
- To select the events you want to trace, specify USRP on the GTF
macroinstruction and select the required event identifiers (EIDs)
as shown in the following examples:
- VTAM buffer EIDs: FEF FF1 FF0 (EFEF EFF1 EFF0)
- VTAM line trace EIDS (not formatted by GTFTRACE): FE4 FF2 (EFE4 EFF2)
- VTAM I/O trace EID: FE1 (EFE1)
- VTAM internal trace EID: FE1 (EFE1)
- VTAM 3270 IDS trace EID: F90 (EF90)
See Activating network traces for more information.
Note: To prompt the system for VTAM records, specify USRP in the parameter field of the GTF procedure. You must code a GTF procedure that is used by VTAM only. If you do not, you will get GTF USR output that contains unwanted records.
