Explanation: TCBADDRESS is a mutually exclusive, optional
parameter, specifying which active DFSMShsm request to cancel. The
request corresponding to the specified TCB address will be canceled.
The following variable is required when using the TCBADDRESS parameter:
- X'tcbaddress'
- Is the 8 digit hexadecimal value returned by the QUERY ACTIVE(TCBADDRESS)
command for which the corresponding request should be canceled.
Note: - Volume level activity will continue with the next data set after
a data set task is canceled.
- When an FRRECOV COPYPOOL FROMDUMP volume recovery request is canceled,
the remaining volume recovery requests will continue to be processed
and the FRRECOV request will fail.
- To avoid the possibility of hung tasks, enter the HOLD command
for all functions before entering the CANCEL TCBADDRESS command.
- When canceling a hung journal backup task, allow any active CDS
backup tasks to run to completion. If a CDS backup task is also hung,
cancel it before cancelling the hung journal backup task.
Defaults: None.
