Re: [Veritas-bu] RMAN crosscheck
As long as you have autobackup enabled, you shouldn't need the rman repository. If netbackup has the images in the catalog, restore the control file from autobackup, which has the rman pieces info and will poll netbackup for the images associated with them.

We had a similar issue a few weeks back where Netbackup could still see images in its catalog of oracle backups (which initiate a RMAN backup via the oracle_backup.sh script) but RMAN had already expired them inside its own catalog. These files were not recoverable by RMAN. We had the DBA's set their retention inside RMAN to match the retention specified inside NBU so that we don't see this mis-match again. Ultimately, RMAN controls the expiration of the images inside its catalog meaning that regardless of the expiration you set for oracle backups inside NBU, RMAN will keep or expire those images, regardless of what Netbackup is trying to tell it. I don't know how you'd configure RMAN to handle your vaulting needs. Would setting the expiration of these images in RMAN to the longest required length of time (4 months for example) mean that the vaulted images would still be good for the max time they'd need to be held on either the Data Domain or tape ? The Netbackup catalog doesn't need to know about the RMAN images for them to still be recoverable by RMAN so you could set a different, shorter expiration inside NBU although this would still leave you with different retentions in the two different catalogs FYI The solaris client we were trying to restore these RMAN images to is running 6.5.4 with a 7.0 master and media server.

Essentially I gather that when they ran it the crosscheck seemed to report even backups run in the last 2 days as expired. On checking the Data Domain unit I can see the images are still there and on running NetBackup commands I see these are NOT expired from NBU's perspective. On doing a search I did find a document at Symantec that talked about RMAN expirations but it only went up through 6.0 so I'm not sure if it is still valid for 6.5. It says essentially that on the NBU side we should set very long retentions (e.g. INFINITY) for all RMAN backup policies then let RMAN keep track of retentions itself. The downside I see to this is we do vaulting of the images on data domain to tape - we set retention on data domain to 1 month then the vault copies get longer retentions (e.g. 3 months for a daily backup). How would we get RMAN to set and keep track of such retention differences? The DBAs have opened a TAR with Oracle to see why the crosscheck is reporting the images as expired but I suspect from the NBU document that the answer will be something like "it is expired so far as RMAN is concerned". This also begs the question as to whether RMAN could be used to restore the backups even if they aren't expired so far as NBU is concerned. Does anyone know the answer to that? Proud partner.

Re: [Veritas-bu] netbackup master single threaded vs. multithreaded
William, Thank you for the response. I think staggering jobs is really my only option in the short-term, which I've already done to a large extent. Due to a strict 'non-business hours' window, which is ~7500 jobs a night and growing, I'm trying to defuse a ticking time-bomb. The T5220's have been a great media servers for us, we rarely push them to any limits. I actually made a big push for a couple M4000's as a replacement master/standby master improve the environments ability to scale, but management is refusing to deploy anymore SPARC in the environment in favor of x86. As far as IOP requirements to support the Sybase db itself, we ended up moving the entire /nbu volume to SAN luns striped across 100+ spindles, which ending up having no effect on the eval timee. I've had an ongoing case with Symantec open to try and get them to fess-up about the single-threaded model of the NBRB, but it is simply a limitation of the product they will have to address in a future release, hopefully 6.5.5! Good luck with the M4000's, let me know if you see any benefit from tweaking the Sybase cache usage. It seems to me as long as your max cache limit is high enough, it will resize in realtime to keep up with EMM requests.

However we did have long discussions with Sun and Symantec about this, as Sun raised it as a possible issue as the Sybase ASA is single threaded. We had decided that on balance the T6320 (which is the same as the T5220 but in a blade format) would be OK as we would be dividing our NetBackup environment into a low number of separate 'medium sized' domains, which related to the DR design. The 'balance' is that the multi-threading is very suitable for the numerous daemons that the Master Server runs, and we can have 10GbE directly off the processor using the XAUI pass-through, so it should cope well with the chit-chat on the network. Our DR plan changed so we went back to a single large domain, and we've gone back to an M4000 - faster CPU cores but many fewer threads. We've not implemented it yet so I'll have to take a rain check on how it works out. It is a very expensive solution compared to the T5220, but then one M4000 is cheaper than 8 T5220s. My understanding is that there is a plan to get a multi-threaded Sybase 'sometime' but I guess a cheap database has cheap features. As you've got the T5220 I'd persevere, but maybe try and get Sun to help look using dtrace to make sure there are no tweaks in the OS - there are some potted solutions on the net, though none I've seen specific to NetBackup. I'd also look at the database quite closely. Put your DBA hat on. We plan to make the changes to the cache that are available as we have tons of RAM. We are separating the database, index, and transaction logs onto 3 separate file systems. Until we use seriously it I don't know if the EMM database disk performance is an issue - but it is worth looking for fast performance so use RAID 0+1 not RAID5 etc. I'd love to try out the Sun SSDs on the EMM db! They say that measured in IOPS they are already cheaper than getting the same IOPS with ordinary disks - of course in capacity they are still way expensive, but if that was your bottleneck it might be cheaper than another new server. There is also tuning advice to stagger the start windows of your backups, as the resource broker has a self-limiting ability to find resources for jobs. That means that if all jobs have a start window say at 18:00, some will start way past that just because the scheduler hasn't even thought about them. You can see that if you create a vast pile of jobs eligible to be considered, it is going to take ages for the scheduler to go through the numerous options to pick the winner. If you can stagger the windows, it will work through the list quicker, and jobs will start more predictably near the start of their windows. Look at page 50 of the tuning guide under ?Staggering the submission of jobs for better load distribution?. May mean changing the habits of a lifetime.

[Veritas-bu] netbackup master single threaded vs. multithreaded
Hello, Has anyone here had performance problems with 6.5 masters running on Solaris with T5220 or T2 Sparc class processors? I have noticed that during periods of heavy job load the nbrb evaluation cycle, which appears to handled via a single threaded dbsrv9 process, can take forever and leave jobs stuck between requesting & granted resources states. Sometime for 15 minutes a time, depending on the job load. I am familiar with nbrb.conf tweaks, however this doesn't make much difference in my environment where we have many disk-based destinations. Seems like in large environments, the master needs to be on a processor better suited for single threaded performance. Thoughts? This message is private and confidential.
