Recovery Manager Utilities

Recovery Manager for Oracle User’s Guide

The virtual copy used for cloning a database must be either an online or offline virtual copy

(created using the

vcdba_create or vcdba_sync command). The virtual copy must have

been mounted using the vcdba_mount command prior to running this command.

A clone database can be created using an ascii or binary controlfile which was saved in the

Recovery Manager repository at the time the virtual copy was created. Using an ascii

controlfile is more flexible as it allows you to change database instance name as well as the

structure of the database.

When using an ascii controlfile, the structure of the clone database is not required to be

exactly the same as the structure of the primary (original) database. Therefore the virtual copy

can be mounted at any mount point. However, since the virtual copy does not contains online

redo-logs and control files, their locations can be specified using the -d option (can be one or

more directories or ASM diskgroups, depending on the desired multiplexing). The number of

multiplex redo log locations must be equal to, or less than, the primary database when

creating the clone database. Otherwise, the extra redo log multiplex location will be ignored.

If the locations of the redologs and controlfiles are not specified, they will be created at the

repository location for the virtual copy (/etc/3par/solutions/<host>.ora.<sid>/

<vc_name>).

When using a binary controlfile the structure of the clone database must be exactly the same

as the structure of the primary database. Therefore, the virtual copy must be mounted at '/' if

the datafiles and archive logs are on file systems. Also, since the virtual copy does not contain

redologs and archivelogs, the same directory structure or same ASM diskgroups for the

redologs and controlfiles must be pre-created on the backup host.

When creating a clone database for backup (RMAN) purposes, the database is started in

MOUNTED mode using the binary controlfile from the repository without recovering the

database. This can be achieved by using the -o for_backup or -o binary, norecovery

option.

A clone database can be created with or without automatic recovery (applying archivelogs

from the virtual copy) using the –o recovery or -o norecovery option. If recovery is chosen

the clone database is open with a reset log, otherwise, the clone database is in a mounted

status.
