Use the R/M trace to perform 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
