Configuring OSB Parameters in RMAN
Problem
You want to configure Oracle Secure Backup (OSB) media management parameters in RMAN.
Solution
You can specify the following OSB parameters in a backup or restore job in RMAN:
•
ob_media_family [_n]:
specifies the media family to use for a job
ob_device [_n]:
specifies the tape drive to be used for the job
•
ob_resource_wait_time:
specifies the length of time for which a job should wait
for a necessary resource to become available
•
You can specify media management parameters in RMAN in two ways. You can use environment variables via
the
configure
or
allocate channel
command. Or you can use the
send
command. We'll illustrate both methods
in this solution.
Using the Configure or Allocate Channel Command
Use the
parms
parameter to send instructions to the media manager from RMAN. In the following example, we use the
configure channel
command to specify values for the
ob_device
and
ob_media_family
parameters:
RMAN> configure channel device type sbt
parms='env=(ob_device=drive3,
ob_media_family=med_fam1)';
The previous command specifies the
ob_device
parameter to direct the backup to the tape drive drive3 and the
ob_media_family
parameter to specify the media family
med_fam1
for the backup.
You can also use the
allocate channel
command to specify media management parameters, as shown in the
following example:
RMAN> run
{
allocate channel ch1 device type sbt
parms 'env=(ob_device=drive3, ob_media_family=med_fam1)';
}
This
allocate channel
command uses the
env
parameter of the
parms
option to specify the media family
med_fam1
for the backup.
