Re: TAPVRT01 and image catalogs ? -- MIDRANGE-L

I guess I will try it with the data area. I found an API to get the
information as well.

Tape Volume 1-6
Backup start timestamp
Backup end timestamp
Did backup complete? Granted, if you have a backup end timestamp...
Backup job name
backup job user
backup job number

BRMS? I've used it with Virtual.

Perhaps you're still thinking sequential and not random. If you start
thinking random what's to stop you from

/* Calculate day of week, and week of year via easy to use SQL functions
*/
/* Translate above to MONW01, MONW02, TUEW01, TUEW02 and so on... */
SAVLIB LIB(MYLIB) DEV(TAPVRT01) VOL(&TapeVol)
Don't like that? Perhaps of concerns about 53 week years? (Let's not go
down that tangent.) Then store last used into a data area and increment
it during the next save. Maybe even store some extra stuff in the data
area like date/time it was last backed up.

I have been running some tests with this for backups, seems to work pretty
good. I have hit a couple of problems.

I have 14 indexes defined to basically depict 2 weeks worth of tape
volumes.

let(s) say last night I wrote to index 5, I have a job scheduler job to
flip it to the next one prior to the next backup.

but yesterday someone looked a index 2, when done the image catalog
remained at #2 and then well #3 got used to do the backup instead of the
next one that should have been used.

sooo....

I don't see a rtvimgclge command, is there a way to get index and other
values via an API.
Is there a way to control that if the currently mounted index is changed
it
will revert back to the orginal one I was using(I don't think so). It
seems if I am going to use mulltiple indexes in a round robin approach
then
I am going to have to somehow keep track what was the last one I used.

Looking for ideas to keep the 14 day cycle in sync.
