Re: [Veritas-bu] older version issue.... netbackup 6.5.6
sshapiro currious why you are running a database that is about ten years out of support, especially if your DBAs do not want to use the tools native to that version. Glad you got your problem solved, did not suggest start/end scripts as I understood that you wanted a RMAN like solution which was why I suggested EBU. How do you handle the archive logs generated by database while it is in backup mode ? Thinking in RMAN scripts you usually do the online backup and a then backup of the archive logs Regards Michael 2015-07-20 20:15 GMT+02:00 sshapiro nbu-fo...@backupcentral.com: Only got one emailed reply to this - suggested EBU. Not an option. Our DBAs have no interested in trying to set up yet another unsupported system. I resolved this by avoidance, in case anyone is interested. I set up a new netbackup policy to just backup the oracle DB filesystems and archive log filesystems. Then using pre-and poost scripts (bpstart_notify, bpend_notify) I put the database into backup modes, started a new archive log, do the backup, then when complete, take out of backup mode. pre and post scripts work pretty well! +-- |This was sent by sid_shap...@bio-rad.com via Backup Central. |Forward SPAM to ab...@backupcentral.com. +-- ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu

Hi thanks for sharing your experience. Can you please paste output of bp.start and bp.end scripts. It will help us understand better.

Congrats on testing! As you found, it is important to also get the archive redo logs post-backup. Cheers, Wayne ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
Re: [Veritas-bu] older version issue.... netbackup 6.5.6
Hopefully your database server is also a media server. The command we use on our remaining HP-UX 11.11 media server (running NBU 7.6.x but same was used back when we had 6.5.x) is: /usr/openv/netbackup/bin/bpbackup -p policy -s schedule -i dbbackup.log 21 We define the policy in NetBackup using multiple streams but do not set any days in the schedules for “Start Window” tab. We set the frequency to allow it to be run every 12 hours. We do multiple streams to backup separate subdirectories for the database to make it run faster – one could specify separate data and index files in the streams if all in one directory – we used to have separate filesystems so maintained separate directories when we went to a single filesystem to make this backup stream assignment more manageable. Hot backup mode in Oracle causes a lot of logging while it is running so if left running too long might fill up your redolog or archive log dump spaces. We do hot backup mode but only to do the split of data to other host so it only runs on our main database for a few minutes so we are doing a point in time backup which is probably what you did. One thought – I haven’t worked with NetApp in years but I notice you said “snapshot” rather than “BCV” so I’m wondering if your NetApps might allow for full copy vs snapshot. We did full copies when we had EMC Symmetrix then DMX and now do same on our Hitachi (they call it Shadow Image) and it is the full copy (i.e. a mirror of the original data) that we break off and mount on our backup server. We do it this way because snapshots create pointers back to original data and we don’t want Production during the day impacted by the backup reads. Flow is generally: 1) Start background copy of production disks to other disks (or LUNs) using the disk array’s facility for this (BCV or Shadow Image in our case). 2) Once the background disks (LUNs) are fully synced we put the database into hot backup mode. 3) We split the backgrounds disks (LUNs) from the production disks. 4) We take the database out of hot backup mode. 5) We mount the background disks on the backup server. 6) We do the backup (usually runs from early morning to midday) on the backup server. 7) In the evening we unmount the background disks (LUNs) from the backup server and start again from step 1. For the unmount and mount we’re also exporting LVM VGs (previously deported VxVM DGs) before the unmount then doing import before the mount.

Background (kind of long-winded, but I want to tell you as much as I can to forestall unrelated questions): I have a database that is currently running on an EMC cx3-80 backend.

I've burrowed down to the problem being that the bpbackup command, which is being called directly from the hot backup script, is returning a EXIT STATUS 29: failed trying to exec a command. We've chased this a bit. I've run bp' to backup some files and that works fine. I've captured the arguments that bp uses to call bpbackup and tried to use the exact same command and arguments calling bpbackup directly. bp works, bpbackup does not, even though they are running the exact same bpbackup command. I've tried the bpbackup command on various other systems: aix 7.2, hp-ux 11.31 - all work correctly. It is only on hp-ux 11.11 and 11.0 that I'm seeing the problem. symantec says error 29 indicates a permission and/or resource problem. Obviously that is not the case if bp calling bpbackup works and calling bpbackup directly does not. There is something else going on. btw - the command I'm trying is bpbackup -S herhxp03 /etc/passwd
Re: [Veritas-bu] older version issue.... netbackup 6.5.6
Thanks - I'll look into EBU. NetApp can generally do snapshots, but (1) we were trying to move as much as we could to rman, (2) our current snapshot procedure is pretty cumbersome and I expected it to remain as kludgey on NetApp, and (3), we think that Unix snapshot might be a seperately licensed NetApp piece that we were trying to avoid. All the bpbackup tests were running as sudo to root. / Sid / -- Sid Shapiro sid_shap...@bio-rad.com Bio-Rad Corporate IT - Desk: (510) 741-6846 Mobile: (510) 224-4343 On Wed, Jul 15, 2015 at 9:37 PM, Mian71 mia...@gmail.com wrote: Hello Sid Have you tried to use EBU which it is the RMAN for Oracle 7.3.4 It did work with netbackup libobk back in NetBackup 3.4 NetApp should be able to create snapshots the volume, at least it could when I worked with it.
