I'm looking for suggestions on the following problem:
We'd like to allow users to do application "backups". I use the term
"backups" loosely so as not to prejudiced towards/against either
VMARCH/VMBACKUP.
At various points in the day/week/month users do mass update of their
database. They would like to freeze the data at a point in time so that
they have known point of recovery if things get all hosed up.
A user exec needs to initiate a "backup" sequence wait for its completion
syncronously, and then continue with the database load/refresh/whatever.
Things we've considered:
1) VMTAPE and MOVEFILE, TAPE DUMP, etc.
+ no special priveleges required by end users
- no catalog, not very friendly, not easily queryable
2) VMARCH - we have some staging and of course offline, no "DASD"
+ users are familiar with VMARCH
+ we know how to query for jobs enqueded and hold the submitting
exec until complete.
- haven't thought of good way to initiate the processing of OFFLINE
requests immediately (files are typically large-ish to large).
3) VMBACKUP
+ we know how to query for jobs enqueded and hold the submitting
exec until complete.
- template administration
- no granularity in ADMIN commands to create template, execute A
SPECIFIC job.
- concerns on how to initate the processing of backup job
4) Seperate SVM for either VMARCH or VMBACKUP where operator/admin
functions could be given to users without endangering the SYSTEM wide ones.
-+ Have only just begun looking at this.
Any ideas/pointers would be appreciated.
