When to use the record management trace facility

Use the R/M trace to do these tasks:

Capture data when a problem occurs.
Problems include incorrect data in a data set, missing records, incorrect control block information, and program checks because of incorrect data and/or fields in VSAM R/M control blocks.
Capture VSAM R/M control blocks before an error code is passed back to the caller.
VSAM R/M control blocks are captured before the calling program can:
- Erase or overwrite the VSAM data
- Abnormally terminate
- Close the data set, freeing VSAM R/M control blocks.
