i am getting the following error, when trying to run RMAN backup on Oracle 10g database using netbackup. please help!

The backup runs for about an hour or so and from what my netbackup admin tells me, it backs up about 150 gb of the total 270 gb and then it fails giving me the following error.

please help, i am going live with this system on saturday and the backups have to work.

FYI, this is my first time backing up this database. i have registered it in the catalog.

Does the error, ORA-19513, sequencial file not found error mean that it is looking for a previous sequence of the datafiles etc and it cannot find it and hance it is failing?

Please help. thank you!

>>ORA-27206: requested file not found in media management catalog
This has nothing to do with RMAN.
Some configuration in netbackup is not correct. I would particularly check for Client_Name.

Hi Mahesh,

thank you.

For some reason, it still backs up ONLY 150 GB and not the complete 260 GB database.

I changed my script from filesperset 500 to filesperset 40, which should make it a smaller backupset.

But is there a LIMIT either on netbackup or within oracle or RMAN, that limits the size of the backup to 150 GB ? how do i find out about that in ORACLE ?

Thank you!

RMAN> run {
allocate channel t1 type 'SBT_TAPE';
send 'NB_ORA_SERV=laxas4bkp01, NB_ORA_CLIENT=laxas4odb01';
backup
incremental level 0
skip inaccessible
format 'bk_%s_%p_%t'
database
filesperset 500;
sql 'alter system archive log current';
release channel t1;
}

Not essentially.
You limited only the number of files. Not the size of individual backuppiece.

>>For some reason, it still backs up ONLY 150 GB and not the complete 260 GB database.
Post the exact log.
Again, if it is the same error, did you check your netbackup configs?

the error that i am getting is as below:

but when my netbackup admin is monitoring the netbackup, it backs up upto 150gb and after that it fails.

there are other backups on the same tape library, which are larger than 200 gb and they all backup fine. it is just this one that fails at 150gb.

would u recommend i restrict the size of inidvidual backup piece? if so how do i do it? i am running out of time, please help. thank you!!

As Mahesh has already indicated, I would suspect it's a Netbackup configuration issue. May want to check the netbackup logs and also verify that the netbackup client was linked properly. Has this ever worked on this node/database?

In answer to your other question, you can limit the size by specifying MAXPIECESIZE.

hi ebrian, Mahesh,

backup has never worked on this node before.

netbackup client is definately linked to the oracle library properly.

if i change the MAXPIECESIZE setting to as follows, u think it may help?
RMAN> CONFIGURE CHANNEL DEVICE TYPE DISK MAXPIECESIZE = 100G;

when i run the backup manually from RMAN command line, i get the following error instead of the other one,

hi again,

it there was a problem with the netbackup configuration, how would it even write 150gb? shouldn't it just fail right away? is there any limit in oracle that i should be aware of that probably kills the backup after 150 gb?

thank you!

There appears to be a similar bug 7191856 for this same issue albeit on Win2k3 with NetBackup. You may want to file an SR with Oracle.

Please keep us informed.
