ABA has been designed to assist you in identifying data sets related
to an aggregate group. You need to ensure that all data sets necessary
to rebuild the working environment are identified and collected during
the aggregate backup process.
Note: Although the output
selection data set is in a form that may be usable as input to the
aggregate backup function, you need to examine closely and modify
the selection data set, if necessary, before actually using it in
an ABACKUP command. If you use the data set created by ABA as input
to aggregate backup, the data set name must be the same as the selection
data set in the aggregate group.
When verifying the contents of the ABA-generated selection data
set, look for problems such as the data set:
- Not containing all necessary data set names associated with the
aggregate group (data sets not allocated or not opened during the
SMF interval)
- Containing data set names that are not part of the aggregate group
- Containing data set names that no longer exist (flagged as uncataloged)
- Containing tape data set names that can be moved to an ACCOMPANY
list
- Containing DASD data set names that can be moved to an ALLOCATE
list
The following hints assist you in determining which data sets to
back up and how to collect them.
Uncataloged data sets: ABARS does not support
uncataloged data sets. If you want to back up uncataloged data sets,
you should manually catalog the data sets before issuing the ABACKUP
command. Any uncataloged data sets you do not choose to catalog should
be removed from the ABA-generated selection data set.
Nonaggregate group data sets: The generated
selection data set may contain the names of data sets not in the aggregate
group; for example, SYS1.LINKLIB. When these data sets are to be excluded,
you must delete their names from the generated selection data set.
DASD data sets: The contents of some DASD
data sets may not be required for execution of an application. Data
set names that are used only for output should be moved to an ALLOCATE
list.
Tape data sets: Tape data sets are candidates
for the ACCOMPANY list in the selection data set. If you do not want
the burden of copying the tapes, the tape data set names should be
moved to the ACCOMPANY list.
