NetVault Plug-in for Oracle 11.3 - User Guide

•

To restore a Duplicate Database backup to the same server, the following prerequisites must be met:

•

Same version of Oracle® Database software: The version and edition of Oracle for the destination database must be identical to the version and edition of Oracle being used for the source database. This requirement includes identical patch levels.

•

Duplicate Database backup available: A Duplicate Database backup must be completed successfully and made available.

•

Source database in open state: The source database must remain in an OPEN READ WRITE state during the entire Duplicate Database restore process.

•

Auxiliary instance prepared: RMAN’s backup-based Duplicate Database process requires the preparation of an auxiliary instance:

Oracle password file for auxiliary instance created: Required if you want to use a password file versus OS authentication for the auxiliary connection when duplicating to the same host as the source database. For more information on creating a password file, see Creating and Maintaining a Password File in the Oracle Database Administrator’s Guide.

Oracle Net connectivity established to auxiliary instance: The auxiliary instance must be available through Oracle Net by adding the instance to the “tnsnames.ora” file. Additionally, on Windows® platforms, perform the following command to start the instance:

oradim -new -sid <sid_name>

Auxiliary instance destination directories exist: The following destination directories for the auxiliary instance must be created on the server where the destination database resides. If the destination database stores its datafiles in ASM, the ASM instance name for the destination database must exist.

•

•

•

•

•

PFILE created for auxiliary instance: A client-side PFILE for the Auxiliary Database must be created from the SPFILE of the source database.

•

Start SQL*Plus, and connect with administrator privileges to the source database.

sqlplus sys/<password>@<source_connect_identifier> AS SYSDBA

•

Create a PFILE from the SPFILE.

create pfile = '<PFILE_destination_directory>/

init<auxiliary_sid>.ora' from spfile;

PFILE updated with auxiliary values: The PFILE created for the auxiliary instance must be updated with the parameter values specific to the auxiliary instance.

•

Remove all entries that begin with: <source_sid>.__

•

Update the *.db_name= entry to reflect the name of the destination database.

•

Update the following entries to reflect the destination directory for the auxiliary instance. This directory must exist; however, if the source database stores the datafiles in ASM, the ASM instance name for the destination database should be specified for each of the following control_files and db_create_file_dest parameters:

*.audit_file_dest=

*.background_dump_dest=

*.control_files=

*.user_dump_dest=

•

NetVault Backup software and the Plug‑in for Oracle installed: The same version of NetVault Backup software and the plug-in must be installed and configured on the alternate server where the destination database resides.

When configuring the plug-in on the alternate server, ensure that the following Default Attributes are defined:

•

NetVault Backup: Specify the name of the NetVault Backup Server where the source database server was added as a NetVault Backup Client.

•

Do Restore From NetVault Backup Server: Specify the name of the NetVault Backup Server where the source database server was added as a NetVault Backup Client.

•

For more information, see Configuring default settings.

•

Source database added to Plug‑in for Oracle installed on alternate server: The source database must be added to the plug-in that is installed on the alternate (standby) server where the destination database resides.

For example, the production Oracle Server is named salesdb. On the alternate server that has the plug-in installed, add a database named salesdb. You complete this step even though the existing database has not yet been cloned to the alternate server. This step forces the plug-in to create a placeholder that can then be accessed during the cloning process when the Oracle database is restored to the alternate (standby) server.

For more information on adding a database, see Adding a database. These instructions work for the original database, as well as the placeholder that you create on the alternate server.
