Setting Destination Details

If the SYSDBA user name or password or the Oracle® SID for the database has changed since the time of backup, set the following options for the restore job on the Destination Details tab:
•
Target Service: This option is required only if the current SID for the Oracle DBID has been changed since the backup was taken.
•
Oracle SYSDBA User Name: Specify the new SYSDBA user name if changed.
•
Oracle SYSDBA Password: Specify the password associated with the name specified in the preceding field.
 
* 
IMPORTANT: The Destination Details requires that the DBID of the backed-up or source database match the DBID of the destination database. When the goal of the restore is to create a duplicate of the source database to a database with a different DBID, using a Duplicate Database backup is required. For more information, see Duplicate Database backup.

Setting the Recovery Catalog details

While the Recovery Catalog information is provided for backups on the Configure or Add (or Edit) Oracle Database dialog box, set the Recovery Catalog configuration for a particular restore job by configuring the Recovery Catalog information on the Recovery Catalog tab.
•
Use Catalog: Select this option to use the RMAN repository in the Recovery Catalog and store information about this restore operation in a Recovery Catalog. Clear Use Catalog when performing a test recovery.
The following fields are enabled when you select this option:
•
Catalog Instance Name: Enter the Oracle® Instance name (which might differ from the Oracle Net Service name) for the Recovery Catalog database. This instance name must be defined in the “tnsnames.ora” file on the Oracle Database Server so that the plug-in can connect to the Recovery Catalog database. If the Recovery Catalog was used during the backup, the Instance Name field defaults to the Oracle Instance name used during the backup job.
•
Catalog Owner: Specify the user that was specified as the owner of the Recovery Catalog and was granted the RECOVERY_CATALOG_OWNER role.
•
Catalog Password: Provide the password associated with the Catalog Owner name specified in the preceding field.

Setting the Clone Database options

The Clone Database tab is available only when an RMAN DUPL DB backup is selected on the Create Selection Set page. You can use it to specify the options for restoring a Duplicate Database backup to a destination database. For more information on the prerequisites, see Duplicating a database in a non-RAC environment or Duplicating a database in a RAC environment.
•
Duplicate Database: Select this option to restore the selected Duplicate Database backup to an alternate destination database.
•
Destination Database section:
•
Auxiliary Instance: Specify the Oracle® Net Service name of the auxiliary instance. This field defaults to auxdb.
•
Oracle Home: Specify the Oracle Home for the auxiliary instance. This field defaults to the Oracle Home of the source database.
•
Oracle SYSDBA User Name: Specify the SYSDBA user name that is used to connect to the auxiliary instance. This field defaults to the SYSDBA user name specified in the configuration of the source database.
•
Oracle SYSDBA Password: Enter the password for the SYSDBA user name specified in the preceding field.
•
Use nofilenamecheck Option: Select this option to prevent RMAN from verifying whether the datafiles and online redo logs files of the source database are in use when the source database files use the same names as the duplicate database files. You are responsible for determining that the duplicate operation does not overwrite useful data.
This option is required when you restore a duplicate database to an alternate server. Do not select this option if you are restoring a duplicate database to the same server; otherwise, the restore job fails with the following errors:
•
RMAN-10035: exception raised in RPC: ORA-19504: failed to create file
•
ORA-27086: skgfglk: unable to lock file – already in use
•
SVR4 Error: 11: Resource temporarily unavailable
•
RMAN-10031: ORA-19624 occurred during call to DBMS_BACKUP_RESTORE. RESTOREBACKUPPIECE
•
Duplicate From Database section
•
Target Database: Specify the Oracle SID of the target database. This field defaults to the Oracle SID of the database including in the backup.
•
Oracle Home: Specify the Oracle Home for the source database. This field defaults to the Oracle Home of the source database.
•
Oracle SYSDBA User Name: Specify the SYSDBA user name that is used to connect to the source database. This field defaults to the SYSDBA user name specified in the configuration of the source database.
•
Oracle SYSDBA Password: Enter the password for the SYSDBA user name specified in the preceding field.

Setting Generate RMAN Script options

Intended for the advanced DBA, the Generate RMAN Script feature lets you generate most of an RMAN script through the WebUI. Later, before using the script, you can add more options or parameters. With this option, you do not need to create the script from scratch, which minimizes the risk of syntax errors in the scripts and that restores are not performed correctly.
You can set the following options for the Generate RMAN Script feature:
•
Output RMAN Script to File: Select this option to use the feature and enable access to the remaining options, and then enter the name of the file to which the RMAN script is written.
•
RMAN Script Directory: Enter the name of the directory where the RMAN scripts are saved. The Generate Script Default Directory field defaults to the directory specified on the plug-in’s Configure dialog box. However, you can modify the field on a per-backup-job basis. The full path where the RMAN script is saved is built by concatenating the RMAN Script Directory with the filename provided in the Output RMAN Script to File field.
•
If Existing, Overwrite Destination File: Select this option to allow the destination file where the RMAN script is output to be overwritten if the file exists. If the file exists and this option is not selected, Generate RMAN Script fails and does not write output to the existing file. Select this option only if you are sure that you want to overwrite an existing file.
•
Generate RMAN Script and Submit Job: With this option selected, in addition to outputting the RMAN script to the specified file, the NetVault Backup Job is scheduled and submitted. Clearing this option ensures that the plug-in only generates the script, which lets you edit and run the script outside of NetVault Backup.
