Re: How to use RMAN backup database to tape device on HP-UX?

Hi TG,

I need to install "Legato or Vertia or Onmi backup software to get media management library, then I can use RMAN to backup database to tape device directly. right?

Re: How to use RMAN backup database to tape device on HP-UX?

For big database I suggest backup to disk first then to tape.That the backup strategy we use for our production database.The reason is shorter backup time..Backup to disk save us 1 hour of backup time compared to backup to tape.

Eric,
You got it!

you are right!
Another important thing is that the media management along with RMAN works great with tape like to choose the right tape for restore,etc.

Legato comes with Oracle.
Run the installer select Legato and install it with the existing components.


All the Best!

Re: How to use RMAN backup database to tape device on HP-UX?

hi,

By default $ORACLE_HOME/lib/libobk.sl is linked to libdsbtsh8.sl

For the media management software you are installing, you should do the appropriate link. Remember to shutdown the database for performing this operation is crucial.

If you go for legato, again note that Legato Storage Manager is a media manager bundled with Oracle on HP-UX. See Legato Storage Manager Administrator???s Guide.

hope this helps too!

Re: How to use RMAN backup database to tape device on HP-UX?

Hi

We have 2 HPUX and diskarray with serviceguard cluster, omniback and oracle is installed with cluster integration support, omniback and oracle runs separate nodes by default

I have 2 problems

I have currently 3 instances and they are running on same node, when I configured dataprotector 5.0 for last instance, and tried to backup I am getting this error

................
...............
input datafile fno=00006 name=/oracle/OYAK/oradata/indx01.dbf
channel dev_3: starting piece 1 at 07/30/2003 [21:13:15]

...............................
..................................


but the backup configurations of other instances run "correctly", I am not figured out why

the another problem, when I want to configure new Oracle backup, Dataprotector can see only cluster nodes, it could not see Oracle package on cluster,

Could you help me

Re: How to use RMAN backup database to tape device on HP-UX?

I've read other answers in other forums that talk about the "piece" being too large that is being written to tape. The piece size can be controlled by using the "filesperset" parameter:

run {
allocate channel c1 type 'sbt_tape'
filesperset=2
parms="ENV=(BACKUP_DIR=/home/st205/catalogs)";
backup database;
}
