How to Unplug and Plug a PDB Having Encryption (TDE) from One Container to Another

Setup Overview Source Container: CDB01
No of PDB's in Source Container 2 (PDB01 and PDB02)
PDB01 using TDE
PDB02 using TDE
Target Container: CDB02
Note: Even if the PDB you are unplugging and re-plugging to another container, don't have any encrypted object but Wallet keys, are treated exactly same as PDB having encrypted objects.
Task: In this post I will unplug the PDB02 from CDB01 and Plug it in CDB002 on the same host without copying the datafile (using NOCOPY Method).
Precheck
1) Perform Full PDB backup of PDB02 database.
2) Create PDB description XML file for PDB(PDB02)
SQL> exec dbms_pdb.describe (PDB_DESCR_FILE=>'/u01/app/oracle/PDB02.xml', PDB_NAME=>'PDB02');
3) Verify the status of the PDB.
SQL> select pdb_name, status from cdb_pdbs where pdb_name in ('PDB02');
4)  Checking the Compatibility of the PDB with the Target CDB
SQL> BEGIN
IF dbms_pdb.check_plug_compatibility('/u01/app/oracle/PDB02.xml') THEN
dbms_output.put_line('no violations found');
ELSE
dbms_output.put_line('violations found');
END IF;
END;
/
SQL> SELECT type, message, action FROM pdb_plug_in_violations WHERE name = 'PDB02';
At this point resolve if there is any violation found. If not proceed with unplug

How to Unplug a PDB Having Encrypted Objects from CDB to Plug into Another CDB

Step1> Check if wallet keys are available in Source PDB
SQL>col creator for a5
SQL>col key_use for a10
SQL>col keystore_type for a25
SQL>col origin for a10
SQL>col creator_pdbname for a15
SQL>col activating_pdbname for a15
select con_id,substr(key_id,1,6)||'...' "KEY_ID...",creator,key_use,keystore_type,origin,creator_pdbname,activating_pdbname from v$encryption_keys;
    CON_ID KEY_ID...     CREAT KEY_USE    KEYSTORE_TYPE             ORIGIN     CREATOR_PDBNAME ACTIVATING_PDBN
---------- ------------- ----- ---------- ------------------------- ---------- --------------- ---------------
         0 AdiYqO...     SYS   TDE IN PDB SOFTWARE KEYSTORE         LOCAL      PDB02           PDB02
1 row selected.
As you can see PDB02 is very well having the wallet keys. Once the PDB is having the wallet keys, you must export/import the wallet as well to be able to unplug and re-plug the PDB in another container, even if the PDB don't have any encrypted object.
Step2> Export the Wallet Key from Source PDB
CDB011> alter session set container=PDB02;
Session altered.
CDB011> administer key management export encryption keys with secret "xxxxxxx" TO '/u01/app/oracle/pdb02key.exp' identified by xxxxxxx;
keystore altered.
Step3> Close the Source PDB on all Instances 
CDB011> alter pluggable database PDB02 close immediate instances=('CDB011','CDB012');
Pluggable database altered.
Step4> Unplug PDB database
CDB011> alter pluggable database PDB02 unplug into '/u01/app/oracle/TMP_PDB02.xml';
Pluggable database altered.
Step5> Drop Source PDB database (Keep the datafiles)
CDB011> drop pluggable database PDB02 keep datafiles;
Pluggable database dropped.
Step6> Check Source PDB database Status
CDB011> select pdb_name, status from cdb_pdbs where pdb_name in ('PDB02');
no rows selected

How to Plug an Unplugged PDB (Having Encrypted Objects TDE Enabled )in Same or Different Container

Step1> Prepare the Target Container
The step can be done much in advance to minimize the downtime 
a) Target container should have same options installed as source
b) Important database parameter (eg NLS_CHARACTERSET, DB_BLOCK_SIZE etc) should be same as source
c) Wallet must be created should be open in root container ReadHere: How to Configure Wallet
Step2> Verify the Wallet/Keystore Status in Target Root Container

How to Switch Log File from All Instances in RAC

<<Back to Oracle RAC Main Page Switch The Log File of All Instances in Oracle RAC. In many cases you need to switch the logfile of the database. You can switch logfile using alter system switch logfile command but if you want to switch the logfile from all the instances you need to execute the command on all the instances individually and therefore you must login on all the instances. You can avoid this and switch logfile of all instances by just running the below command from any of the instance in RAC database SQL> ALTER SYSTEM SWITCH ALL LOGFILE;   System altered.

ORA-46630: keystore cannot be created at the specified location

<<Back to DB Administration Main Page ORA-46630: keystore cannot be created at the specified location CDB011> ADMINISTER KEY MANAGEMENT CREATE KEYSTORE '+DATAC4/CDB01/wallet/' IDENTIFIED BY "xxxxxxx"; ADMINISTER KEY MANAGEMENT CREATE KEYSTORE '+DATAC4/CDB01/wallet/' IDENTIFIED BY "EncTest123" * ERROR at line 1: ORA-46630: keystore cannot be created at the specified location Cause  Creating a keystore at a location where there is already a keystore exists Solution To solve the problem, use a different location to create a keystore (use ENCRYPTION_WALLET_LOCATION in sqlnet.ora file to specify the keystore location), or move this ewallet.p12 file to some other location. Note: Oracle does not recommend deleting keystore file (ewallet.p12) that belongs to a database. If you have multiple keystores, you can choose to merge them rather than deleting either of them.
