Viewing the Oracle PDB Database ID

Oracle has introduced the Multitenant feature for Oracle 12c. There are 2 databases that are part of the Mulitenant feature:

The container database (CDB) - This database contains the files that the database needs to run such as the control file, dictionary and redo logs. A CDB can contain one or more pluggable databases (PDB).
Pluggable databases (PDB) - PDBs contain datafiles and tablespaces. They do not contain any control file because they use the CDB control file. Each PDB has a unique database ID.

If you have Oracle 12c, then you can unplug a PDB from one CDB and plug it into a new CDB to simplify software patching and maintenance. When you move a PDB to a new CDB instance, Oracle prunes the database backup information from the original CDB instance and does not update the new CDB instance with the backup information. The Commvault Oracle Agent software keeps track of the CDB at a specific point in time so that you can identify the CDB for a point-in-time restore.

Commvault provides this functionality by including the PDB database ID in backups and providing script that you run from the command line that displays the following PDB information:

The client name where you ran the backup
The Oracle instance name
The Oracle PDB name
The backup job start time of the first PDB backup
The backup job end time of the last PDB backup
The PDB database ID

After you have this information, you can use RMAN scripts to plug the PDB into a new CDB, or to clone the PDB.

Procedure

If you are not logged on to the CommServe computer, run the qlogin command.

On the command line, go to Software_Installation_Directory/Base and type the command.

qoperation execute -af qoperation execscript -sn QS_GetOracle12CPDBBackupDetails -si startTime = 'start-time' -si endTime = 'end-time' -si databaseNameList = 'pdbNameList' -si instanceNameList='instanceNameList' -si clientNameList = 'clientnameList' -si dbIdList = 'dbIdList' -si enableDateTimeFormat = '0 or 1'

Where:

Parameter	Definition
startTime	The backup job start time of the first PDB backup (for the CDB). The format is MM/DD/YYYY HH24:MI:SS.
endTime	The backup job end time of the last PDB backup (for the CDB). The format is MM/DD/YYYY HH24:MI:SS.
databaseNameList	The databases that the software queries. Use a comma (",") to separate each database name.
pdbNameList	The PDBs that the software queries. Use a comma (",") to separate each PDB name.
instanceNameList	The instances that the software queries. Use a comma (",") to separate each instance name.
clientNameList	The clients that the software queries. Use a comma (",") to separate each client name.
dbIdLiast	The database IDs that the software queries. Use a comma (",") to separate each database ID.
enableDateTimeFormat	By default the Commvault software outputs the start time and end time in the epoch format (the number of seconds that have elapsed since 1/1/70) so that you can use them in xml scripts. Set this value to 1 to have the output in date format.

To logoff the CommServe computer, run the qlogout command.

Examples

Using an Instance Name List

The following example uses an instance name list for the query. In this example, the parameters are on the command line.

./qoperation execscript -sn QS_GetOracle12CPDBBackupDetails -si '05/15/2017 00:30:00' -si '05/24/17 03:57:41' -si '' -si 'cdb1,CDB1' QScript[QS_GetOracle12CPDBBackupDetails] CS[172]

The following example uses the enableDateTimeFormat to display the output in date format.

What to Do Next

Run RMAN scripts that plug databases into a different CDB.
