The recovery file records changes made to the security file. When the file is full recording continues at the beginning of the file overlaying existing data.
Recorded changes are written to the security file by running the TSSRECVR utility.
CA recommends that the recovery file be allocated on a different volume than the security file to ensure that if a hardware malfunction occurs recovery using an alternative device or path is possible.
The size of the recovery file is dependent on the interval between security file backups. The file should be made large enough to record two or three days worth of changes for every day in the security backup interval. For example, if the security file is backed up at the end of each day, the recovery file should be large enough to accommodate at least two days worth of changes.
There is no need to backup the recovery file.It is possible to backup to tape using the TSSBCKUP procedure.
Because the TSSBCKUP JCL is set up to point to the security file by default, to backup the recovery file specify a different file name.
Example: Recovery file backup
This example backs up the recovery file:
S TSSBCKUP,'RECFILE'
