Recovering Whole Database to Primary Database Server

This type of recovery is performed when the current Control File and SPFILE are intact but all the datafiles are damaged on the Primary Database Server, and the backup from the Standby Database Server is used for the recovery. You can perform a Complete Recovery or recover the database to a specific point.

An overview of the process to recover the whole database from a backup of the Standby to the Primary Database Server follows.

1
On the Create Restore Job — Choose Saveset page, find the latest available backup on the Standby Database Server that included all the tablespaces, and click Next.
2
On the Create Selection Set page, select the Whole Database node, and click Edit Plugin Options.
3
Click the Restore Options tab, and then select the following:
In the Pre-Restore Options section, select Whole Database Restore.
In the Restore Options section, select Restore/Recover from User Defined Backup Tag, and specify the User Defined Backup Tag for the Standby Database Server.
Perform Complete Recovery: Recovers the database to the current time, that is, to the last committed transaction available in the archived and online redo logs.
Perform Database Point in Time Recovery: Recovers the database to a specific point-in- time, whether it is a specific time, log sequence number, or SCN.
5
On the Recovery Catalog tab, select the Use Catalog option, and specify the Recovery Catalog connection details.
Enter the Target Service of the Primary Database Server, the Oracle SYSDBA User Name, and the Oracle SYSDBA Password.
7
In the Target Client list, select the NetVault Backup Client Name of the Primary Database Server.

Using the plug-in with Oracle Container Databases (CDBs) and Pluggable Databases (PDBs)

Oracle PDBs: an overview

With Oracle Multitenant Architecture, you can create an Oracle database that functions as a multitenant Container Database (CDB). You also can create non-CDB databases. In a CDB, you can create one or more Pluggable Databases (PDBs) or you can opt not to create any. A PDB is a portable collection of Oracle schemas, schema objects, and nonschema objects that are presented to an Oracle client as a non-CDB database. Prior to Oracle Database 12c, all Oracle databases were non-CDBs. For more information, see the Oracle 12c Multitenant Architecture documentation.

Enabling connection to a PDB

To connect to a PDB that you have created, you must ensure that an entry is added in the Oracle “tnsnames.ora” file and the status of the PDB is in read-write mode. When a PDB is created, a default Oracle service with the same name as the Pluggable Database name is created automatically. However, an entry to the “tnsnames.ora” file might not have been added.

The following is an example of a “tnsnames.ora” file with only an entry of a CDB called salesdb:

If not, add the entry manually. The following example shows a manually edited “tnsnames.ora” file after two PDBs, sales_region200_pdb and sales_region300_pdb, have been created:
