Re: [Veritas-bu] Number of retries query

Dave,

This isn't an ideal fix, but it will work--schedule the backups from the client. Basically, just put entries in cron (root or oracle will work) with the commands (or script wrapper around the command) to launch the backup instead of using the NBU scheduler (will have to remove current full/incremental schedules and replace with a user directed that has the appropriate windows). Reason this will work is because the automatic retries only affects backups launched from the master...if it's submitted by the client, it will not retry on failure.

Only real issues off the top of my head are:

1) If client is down or doesn't have network connectivity, you won't see failure to run backup in NBU because the backup will never be submitted.

2) You lose visibility to backup schedules within NBU.

Subject	Re: [Veritas-bu] Number of retries query

Good Morning Dave, I know of no way to change the number of job retries on a policy or client or schedule object. I can see where this would be a nice feature to have. There are many different reasons that a rman backup job can fail. >From a netbackup end of things one could have a 96 error no scratch tapes, A media fault, A network issue. Etc. Or it could be a oracle issue. For something like a media issue that is cleared up on the netbackup end of things I would think that the dba's would want the backup to be retried. For an oracle issue I do not know enough. But either way I believe that you could add the control you require into the script that netbackup runs on the client to run the rman commands. Might not be easy. I am sure other that know oracle can give you a better answer then this, and I look forward to learning. As a simple case of go or nogo without any variance based on the prior failure you could try. In the beginning of the script you could set a state value of "STARTED" into a file on client. At the end of the script the vaule could be changed to "COMPLETE". At the start of the script if the value is not "COMPLETE" the script could give an error return and exit. Someone would have to change the statue value to "STARTED" to enable the script to run. This could be done after clearing the problem. This can also be used to bypass the running of the backup at the script level when the oracle dba's are doing maintenance work on the oracle database. If you use and check for some state value of "BYPASS" then the script could exit with a normal return code and netbackup would not have a backup but would think that everything is ok and not retry. You could also use touch files instead on one state file. Let us know what you end of doing to solve this issue. len -----Original Message----- From: veritas-bu-bounces AT mailman.eng.auburn DOT edu [mailto:veritas-bu-bounces AT mailman.eng.auburn DOT edu] On Behalf Of Dave Markham Sent: Monday, April 06, 2009 8:17 AM To: veritas-bu AT mailman.eng.auburn DOT edu Subject: [Veritas-bu] Number of retries query Guys does anyone know if you can change the number of job retries in xx time period on a per client basis? I currently have the global set at 2 tries per 12 hours which is fine for our needs and good in the fact it will try a failed backup. However the DBA for an RMAN and oracle policy doesn't want this to happen and re-run a backup if there is a failure so i need to try and find a way of setting it to 1 try for just one client. Any ideas?
