Source Environment setup :
Target Environment setup :
We have three PDBs in the CDB, VOL19CDB running on sourceh01 database server.
In this exercise , we will try to take backup of this CDB and then restore one pluggable database (PDB2) on new server.
For this, I referred the below metalink document,
How to use Rman to Restore Of Single PDB in Multitenant to Alternate Server
Step 1) Create a Test table in pluggable database, PDB2
[oracle@sourceh01 VO19CDB]$ sqlplus pdb2user/welcome@pdb2

Step 3 ) Copy the backup pieces and few archive logs to the target database server.
using scp command, copy the backup files to the target server.
Below are the copied backup files and few archive logs that generated around that time
Step 4.) On the target database server, start a new instance with the same CDB name as its on the source database server.
4a) - Start the target instance in NOMOUNT state.
Using a temporary pfile , create and start the target instance in NOMOUNT stage. In this case, I am using below pfile for the new database.

---------------------------------------------------------------------------------------------------
Step 7) After the database restore completes, we need to perform the recover of the the required PDB(which we are trying to restore) excluding other PDBs.
Below is the RMAN command used for this purpose.
run
{
set until time "TO_DATE('27-OCT-2022 10:12:00','DD-MON-YYYY HH24:MI:SS')";
recover database skip forever tablespace PDB1:SYSTEM,PDB1:SYSAUX,PDB1:USERS,PDB1:undotbs1,PDB3:SYSTEM,PDB3:SYSAUX,PDB3:USERS,PDB3:undotbs1 ;
}
As you can see from above, we are exluding all the tablespaces of other two pdbs, PDB1 and PDB3. Only PDB2 will be recovered.
First, lets catalog the archive logs that we copied from source database server.
RMAN> catalog start with '/u01/software/backup/VO19CDB/thread_1';
searching for all files that match the pattern /u01/software/backup/VO19CDB/thread_1
