The Maximum jobs per client value is set to 10. Strange thing is not even the single stream/job of this client is active when the backup is started all of them are queued for 1 or 2 hours before they become active. This client is hosted on solaris and there are two database running on single physical server and both of the database hava seperate logical hostname and are registered seperately on Netbackup. Logically they should be treated as different clients(?) Is there any kind of tracing we can enable on client to have some extra details which may help?

Re: [Veritas-bu] Issues with Oracle backup Netbackup 5.1
Are the oracle backups being issue from an agent such as RMAN? I know in the past the number of simultaneous backup streams are actually pushed from oracle and not netbackup. This was all set up in the RMAN scripts to stream 4 sessions at a time. This has no bearing on me having 8 drives available. Maybe chat to the DBA's Cheers judy_hinchcli...@administaff.com wrote: > Nope, it was not there in 5.1 > > So you have 8 drives - and your storage unit is set to use 8 drives... > correct? > And multiplexing for the storage unit is set to 4 - so you should be able to > have 32 jobs running at once - 4 to each of the 8 drives. 4 x 8 = 32 > > So let's look at something else. > Are you running more than one job per client?

Re: [Veritas-bu] Issues with Oracle backup Netbackup 5.1
Nope, it was not there in 5.1 So you have 8 drives - and your storage unit is set to use 8 drives... correct? And multiplexing for the storage unit is set to 4 - so you should be able to have 32 jobs running at once - 4 to each of the 8 drives. 4 x 8 = 32 So let's look at something else. Are you running more than one job per client? (multistreamed backups) If so lets look at how many jobs per client are allowed. Master server properties, Global Attributes Maximum jobs per client -if this is one or 2 look at what jobs are running and which ones are queue. Has that Client reached it's max number of concurrently running jobs? The Maximum jobs per client property specifies the maximum number of backup and archive jobs that NetBackup clients can perform concurrently. Default: 1 job. This can also be set per client - so if the Global is like 8 but you still have queue, again in the master properties look at Client Attributes See if a client is listed here, if yes then look at the General tab and see if the client has be set to limit the number of data streams The Maximum data streams property specifies the maximum number of jobs that are allowed at one time for each selected client. (This value applies to the number of jobs on the client, even if multistreaming is not used.) -Original Message- From: veritas-bu-boun...@mailman.eng.auburn.edu [mailto:veritas-bu-boun...@mailman.eng.auburn.edu] On Behalf Of Sushil Sent: Thursday, May 13, 2010 3:30 AM To: VERITAS-BU@MAILMAN.ENG.AUBURN.EDU Subject: [Veritas-bu] Issues with Oracle backup Netbackup 5.1 > First in the gui add the column to your view "state details" > That will tell you why a job is not running. > > Could be you have on your storage unit, max drives, or max jobs and if those > have been met then the job will queue. > sorry but i could not find "state details" as column in activity monitor , maybe its not there in 5.1.

Yes it is configured to use all the drives. The client_connect_timeout value is 4000 seconds. Another thing which i noticed is that "Maximum multiplexing per drive" is set as 4 on storage unit.

Re: [Veritas-bu] Issues with Oracle backup NetBackup 5.1
Is your storage unit definitely configured to use all the drives? And this may seem like a strange thing to ask but what is your client_connect_timeout set to on your master server? -Original Message- From: veritas-bu-boun...@mailman.eng.auburn.edu [mailto:veritas-bu-boun...@mailman.eng.auburn.edu] On Behalf Of Sushil Sent: 12 May 2010 16:37 To: VERITAS-BU@mailman.eng.auburn.edu Subject: [Veritas-bu] Issues with Oracle backup Netbackup 5.1 Another thing which i noticed in logs there were many jobs which were in queued state but only 4 drives out 0f 8 were utilised. I can not find the reason why the jobs were queued if the tape drives were available. Strange enough those queued jobs became active after 2 hours.

Re: [Veritas-bu] Issues with Oracle backup Netbackup 5.1
First in the gui add the column to your view "state details" That will tell you why a job is not running. Could be you have on your storage unit, max drives, or max jobs and if those have been met then the job will queue. -Original Message- From: veritas-bu-boun...@mailman.eng.auburn.edu [mailto:veritas-bu-boun...@mailman.eng.auburn.edu] On Behalf Of Sushil Sent: Wednesday, May 12, 2010 10:37 AM To: VERITAS-BU@MAILMAN.ENG.AUBURN.EDU Subject: [Veritas-bu] Issues with Oracle backup Netbackup 5.1 Another thing which i noticed in logs there were many jobs which were in queued state but only 4 drives out 0f 8 were utilised.

Re: [Veritas-bu] Issues with Oracle backup Netbackup 5.1
Sushil Status 54 means NetBackup could not communicate with the client. (In most cases timed out connecting to the client). As for 6, I see them when doing redo logs - If there is nothing to backup it fails with this code. In your case, I am not sure. bpbkar and backint logging should be enabled for the SAP Client to get more info. sorry I could not help anymore Simon -Original Message- From: veritas-bu-boun...@mailman.eng.auburn.edu [mailto:veritas-bu-boun...@mailman.eng.auburn.edu] On Behalf Of Sushil Sent: Wednesday, May 12, 2010 11:44 AM To: VERITAS-BU@mailman.eng.auburn.edu Subject: [Veritas-bu] Issues with Oracle backup Netbackup 5.1 All, I have been facing strange issues with some of the oracle database backups.
