Hi All,
I'd like to propose a change to the cancel process syntax to allow a select statement
as a part of it.
The reasoning for this is that there are often situations where we need to cancel a
process to ensure that there are resources for other scheduled processes. For example
I may have a long running reclaim happening that was kicked off by changing the
reclaim percentage on a storage pool. I know that this reclaim will run into my
overnight backup window, but, there is no way of cancelling the process automatically
from within TSM.
Yes, there are many was to do this externally to TSM, but these all involve running
scripts and exposing powerful passwords to prying eyes.
To address this issue, I suggest the the cancel syntax be modified to allow the
process number of the processes to be cancelled to be supplied using a select on the
process table. This would also require that the cancel command could cancel more than
one process at once.
To use the reclaim issue as an example
The process table contains
PROCESS_NUM: 745
PROCESS: Space Reclamation
START_TIME: 2004-03-11 12:15:27.000000
FILES_PROCESSED: 0
BYTES_PROCESSED: 0
STATUS: Volume R00232 (storage pool TAPEPOOL-B), Moved Files: 0, Moved
Bytes: 0, Unreadable Files: 0, Unreadable Bytes: 0. Current
Physical File (bytes): 412,501,966
Waiting for multiple mount
points in device class ATL3590E (494 seconds).
cancel process where process_num in (select process_num from processes where
process='Space Reclamation' and status like '% TAPEPOOL-B)%')
Does anyone think this is a good idea? Comments?
