STARTKEY and RESUME: Determining the starting point for BCDS processing during command execution
Explanation
STARTKEY and RESUME are mutually exclusive, optional parameters
that you specify to control from which BCDS record the processing
is started during command execution.
- STARTKEY
- Specifies a start key.
- lowkey
- Provides a starting point for processing in the BCDS. The value of lowkey can be up to 44 alphanumeric characters that identify the data set for which you want the deletion of backup versions to begin. Numbers are higher in the range (they follow Z) than letters. The value specified cannot end in a period. If fewer than 44 characters are entered, the value specified is appended with X'00' to make 44 characters.
- RESUME
- Starts processing at the point the EXPIREBV command left off the last time an EXPIREBV command was processed on this host.
Defaults
If you do not specify STARTKEY or RESUME, processing begins at the beginning of the BCDS. If you specify RESUME and the most recent EXPIREBV command processed on this DFSMShsm host did not end early, processing begins at the beginning of the BCDS.
Usage notes:
- During processing of the EXPIREBV command, the current key (data set name) is saved periodically.
