COMMAND
vcdba_mount
SYNOPSIS
vcdba_mount -s <oracle_sid> -p <primary_host> -t <timestamp>
[-m <mountpoin>t] [-r] [-v]
DESCRIPTION
Mounts a virtual copy.
The
vcdba_mount command mounts an existing virtual copy created by the vcdba_create
command on the backup host. The mounted virtual copy can be used for off-host processing
purposes such as backup or database cloning.
The following restrictions apply when mounting a database virtual copy:
■ The virtual copy must have an Available or Mounted(P) status in order to be mounted.
The virtual copy's status can be retrieved using the Recovery Manager display utility.
■ The same virtual copy cannot be mounted concurrently at different mount points.
■ If the database files reside on Veritas VxVM Volumes, only one virtual copy per database
can be mounted at any time on the backup host. This is due to the VxVM disk groups from
different virtual copies of the same database having the same names and so cannot be
imported at the same time.
■ If the database files reside on ASM disk groups, it is dependent on which ASM database
version is installed on the backup host, different restrictions apply as follows:
◆ If the ASM versoin on the backup host is 10.2.0.5 or 11.1.0.7, one virtual copy per
database can be mounted on the backup host. Virtual copies from different databases
can be mounted concurrently.
◆ If the ASM vesrion on the backup host is running versions lower than the releases
mentioned in the previous bullet, only one virtual copy can be mounted at any time on
the backup host. This restriction prevents an Oracle ASM instance on the backup host
from hanging due to some ASM's idle processes still holding a virtual copy's devices,
even though the corresponding ASM disk groups are dropped.
■ If the database files reside on OCFS2 file systems, only one virtual copy per database can be
mounted at any time on the backup host.
