Veritas Storage Foundation 5.1 SP1: Storage and Availability Management for Oracle (5900-1504, April 2011)

■ You must be logged in as the Oracle database administrator.
■ Before you can use the dbed_vmclonedb command, you must
validate a snapplan and create a snapshot.
See “About creating database snapshots” on page 146.
See “Validating a snapplan (dbed_vmchecksnap)” on page 167.
See “Creating a snapshot (dbed_vmsnap)” on page 174.
■ The volume snapshot must contain the entire database.
■ The system administrator must provide the database administrator
with access to the necessary volumes and mount points.
■ Before you can use the dbed_vmclonedb command with the -r
relocate_path option (which specifies the initial mount point
for the snapshot image), the system administrator must create the
mount point and then change the owner to the Oracle database
administrator.
■ The Oracle database must have at least one mandatory archive
destination.
■ In case of mapped mounts, the mapped mount points need to be
created by the System Administrator.
Prerequisites
■ The dbed_vmclonedb command can be used on the secondary
host.
■ In a same-node configuration, -r relocate_path is required if no
mapped mounts were specified or some of the mapped mount
entries were left blank in the snapplan.
■ The initialization parameters for the clone database are copied
from the primary database. This means that the clone database
takes up the same memory and machine resources as the primary
database. If you want to reduce the memory requirements for the
clone database, shut down the clone database and then start it up
again using a different init.ora file that has reduced memory
requirements. If the host where dbed_vmclonedb is run has little
available memory, you may not be able to start up the clone
database and the cloning operation may fail.
■ See the dbed_vmclonedb(1M) manual page for more information.
