The method below works but you should be aware that if every tablespace in
the DB is in hot backup mode at the same time, all writes are queued to the
redo logs and a busy DB will slow to a crawl and go though redo space in a
big hurry.
Another method to do a hot backup is:
Query DB for all tablespace names
for each tablespace in tablespace_list
set tablespace in hotbackup mode
query DB for list of Unix files in tablespace
send files via bpbackup to tape
unset tablespace
loop for next tablespace
Then:
backup control files to trace - send them to tape
roll your redo to archived redo
send all archived redo logs from start of backup time end of backup time
to tape
The set of archived redo logs combined with the file backups are recoverable
by first restoring the files then rolling the files forward to a consistent
point in time using the set of archived redo logs. This method will also
queue writes to redo but only for the tablespace that's in Hotbackup mode at
the time of the write activity.
DB never goes down.

Paul,
You can use the BPSTART_NOTIFY and BPEND_NOTIFY feature to have DBA Shutdown
and backup scripts and
have Netbackup run the backup, and then call scripts to restart the
database.
We use thisfeature to perform hot backups of some of our Oracle databases.
The BPSART_NOTIFY script calls a job to put the tablespaces in backup mode,
then runs the backup policy,
when the backup policy is complete, the BPEND_NOTIFY script is called to
take the tablspaces out of backup
mode and return things to normal. We do this for databases that have
archivelog mode turned on.
In your case, you could use this same process to do what you are describing
to call your DBA scripts to set up the flat files,
then have the standard policy backup the files, then the bpend could call
any further scripts to restart the database, etc.
The advantage to this bpend/bpstart featuer is that the backups
are scheduled from the master server and you do not need a cron job to run
the backups.
I can send you copies of our scripts if you like.

Subject: [Veritas-bu] User Directed Backup and Oracle
Folks,
I am trying to establish policies and schedules to enable me to backup
Oracle databases in the following manner and wanted to know if this is a
sensible approach. Any constructive comments would be much appreciated.
Unfortunatley, my scripting skills are failrly basic.
NetBackup Version 4.5 FP6
Master Server Windows 2000
Oracle clients Solaris 2.6 and 8
We do not want to use RMAN and the NetBackup Oracle Extension because we
want to keep the costs down and simplify the restore process to recovering
flat files. The DBA has scripted routines to backup the databases to flat
files and place those files in a specific directory and I was thinking I
could set-up automated schedules for fulls and incrementals that would
control the backup frequency and corresponding user backup schedules that
would backup the flat files. The user backup schedule would run a script
via its file list that is a wrapper for the DBA's script that calls the
bpbackup command afterwards to backup the flat files to NetBackup.
Can I do this with a standard policy type? I have see something similar for
an Oracle policy type where a wrapper script calls RMAN. Does anyone have
anything similar they could share with me?
I have an additional issue where a database resident on a UNIX client needs
to be backed up in unison with a filestore on a Windows 2000 client. Is
there any way I can relate the two activities and control them through
NetBackup? The logic would have to be something like:
* Shutdown UNIX databases
* Run DBA script to backup UNIX databases
* Run NetBackup backup of UNIX database backup flat files
* Run NetBackup backup of Windows filestore [ideally if this
could be run in parallel with above after database shutdown]
* Start UNIX database
I need to keep the database down while the filestore is backed up for
consistency. I may even need to stop a service on the Windows 2000 system
before commencing the filestore backup. AM I chasing shadows here?
Regards,
Paul Esson
