Using PARMLIB member IDAVDTxx and IDAVDT

After completing the steps in Starting the record management trace function, start the R/M trace function as follows:

  1. Define up to 8 trace entries in PARMLIB member IDAVDTxx. This is described in Syntax of Trace entries in IDAVDTxx.
  2. Start the IDAVDT started task with the START IDAVDT command. Message IDAT0001I is issued to confirm that IDAVDT has started successfully.
  3. Use the MODIFY command to request specific trace functions, as described in Syntax of the MODIFY command with IDAVDT.

Stop the IDAVDT started task with the STOP IDAVDT command. Before terminating, IDAVDT will invalidate all trace entries in the dynamic trace save area to prevent VSAM OPEN from comparing data sets from future OPENs with the trace entries. If you would like the status of trace entries to remain unchanged when IDAVDT terminates, you must use the KEEP option of the READIN function on the MODIFY command.
