Re: Actual save time in BRMS?

[Loyd Goodbar <loyd@xxxxxxxxxxxxxx>]

Here is what DSPLOGBRM shows:

Date sent Time sent Message
 5/18/10   3:08:13  Starting save of list SAVELIST to devices TAPMLB04.
 5/18/10   3:08:15  Change to media controls successful.
 5/18/10   3:08:16  Change to media controls successful.
 5/18/10   3:08:16  Starting save of library VNGDBDTA to devices TAPMLB04.
 5/18/10   3:08:16  Starting save of library VNGCUSDTA to devices TAPMLB04.
 5/18/10   3:08:16  Starting save of library PROD_MOD to devices TAPMLB04.
 5/18/10   3:08:16  Starting save of library PROD_DTA to devices TAPMLB04.
 5/18/10   4:39:26  6398 objects saved from library VNGDBDTA.
 5/18/10   4:39:26  35 objects saved from library VNGCUSDTA.
 5/18/10   4:39:26  2266 objects saved from library PROD_MOD.
 5/18/10   4:39:26  117 objects saved from library PROD_DTA.
 5/18/10   4:39:26  4 libraries saved.
 5/18/10   4:40:00  Change to media controls successful.
 5/18/10   4:40:00  Change to media controls successful.
 5/18/10   4:45:57  68 objects saved from library QGPL.
 5/18/10   4:45:58  Save of list SAVELIST complete.
As you can see, all the library saves reported the same start and stop
times. A question: are these times the same because these four libraries
(excluding QGPL) are in the same step? The control group step in question
is:
30 SAVELIST *OBJ *SYSBAS

...with SAVELIST defined as:
10 VNGDBDTA *ALL *ALL *ALL
 20 VNGCUSDTA *ALL *ALL *ALL
30 PROD_MOD *ALL *ALL *ALL
40 PROD_DTA *ALL *ALL *ALL
50 QGPL *ALL *JRNRCV *ALL

Do I need separate steps to accurately track the save times?

We are on a 9406-810. The spend here is tight, and there is talk to moving
to a big-name TLA (not IBM). Upgrading the tape library will probably not
happen.

Thanks,
Loyd
