Veritas Storage Foundation™ for Oracle 5.0.1 Administrator's Guide

■ You must be logged in as the Oracle database administrator.
■ Before you can use the dbed_vmclonedb command, review the
procedure for taking a snapshot of a database, especially the steps
required to validate a snapplan and to create the snapshot.
See “Summary of database snapshot steps” on page 249.
See “Validating a snapplan (dbed_vmchecksnap)” on page 263.
See “Creating a snapshot (dbed_vmsnap)” on page 270.
■ 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.
■ If SNAPSHOT_MODE is set to offline or instant, a two-host
configuration is required and -r relocate_path is not allowed.
■ The Oracle database must have at least one mandatory archive
destination.
See “Establishing a mandatory archive destination” on page 262.
Prerequisites
■ The dbed_vmclonedb command can be used on the secondary
host.
■ In a single-host and Oracle RAC configuration, -r
relocate_path is required. This command is also needed if the
name of the clone database is different than the primary database.
■ The server_name=svr_name option is required. The svr_name
value specifies the server on which the primary database resides.
■ 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.
