Configuring TDE on a PDB with PLUG and UNPLUG Option

This article describes the process of configure a TDE on CDB and unplugging PDB1 from the CDB1 instance and plugging into the CDB2 instance on the same machine with a new name of PDB2.

1 – Configure TDE Source – CDB (cdb1)

A) Create directory

[root@vm1 ~]# mkdir -p /etc/ORACLE/WALLETS/cdb1
[root@vm1 ~]# mkdir -p /etc/ORACLE/WALLETS/cdb2
[root@vm1 ~]# chown -R oracle:oinstall /etc/ORACLE
[root@vm1 ~]# chmod -R 755 /etc/ORACLE

B) Edit sqlnet.ora and configure the Wallet

ENCRYPTION_WALLET_LOCATION=
(SOURCE=
(METHOD=FILE)
(METHOD_DATA=
(DIRECTORY=/etc/ORACLE/WALLETS/$ORACLE_SID/)))

C) Configure Database – cdb1

[oracle@vm1 ~]$ . oraenv <<< cdb1
ORACLE_SID = [db01] ? The Oracle base remains unchanged with value /u01/app/oracle
[oracle@vm1 ~]$ sqlplus

Moving PDB from On-Premise to Cloud

Be sure that the BUG Fix is applied on the Source Database:

– Be sure that the BUG Fix (18633374) is applied on the Source Database:

– The PSU 12.1.0.2.190416 or higher should be applied also on the source.

On-Premise

1.) Check Status of the Source Database:

SQL> select * from gv$pdbs where con_id=13;

INST_ID CON_ID DBID CON_UID GUID NAME OPEN_MODE RES OPEN_TIME CREATE_SCN TOTAL_SIZE BLOCK_SIZE RECOVERY SNAPSHOT_PARENT_CON_ID

2.) GLobal user for DB LInk:

create user c##_link identified by link001#;

grant dba to c##_link container=all;

grant create pluggable database to c##_link container=all;

3.) Close the database:

SQL> alter pluggable database pdbtest close instances=all;

Pluggable database altered.

SQL> select * from gv$pdbs where con_id=13;

INST_ID CON_ID DBID CON_UID GUID NAME OPEN_MODE RES OPEN_TIME CREATE_SCN TOTAL_SIZE BLOCK_SIZE RECOVERY SNAPSHOT_PARENT_CON_ID

11.) Update the backup TDE information for the PDB

After create the PDB on the cloud

In order to have the backups running, you must update the TDE Key for the new PDB Created/Attached.

DBCS OCI: How to create a new PDB in an OCI CDB? (Doc ID 2438598.1)

as root user on the CLoud DB Server:

dbcli list-databases

dbcli update-tdekey -i 040e267b-2719-453a-8c86-52844dcd3032 -p -n PDBTEST

Configuring TDE on a PDB with PLUG and UNPLUG Option

This article describes the process of configure a TDE on CDB and unplugging PDB1 from the CDB1 instance and plugging into the CDB2 instance on the same machine with a new name of PDB2.

1 – Configure TDE Source – CDB (cdb1)

A) Create directory

B) Edit sqlnet.ora and configure the Wallet

C) Configure Database – cdb1

D) Export Key from Source – PDB(pdb1)

E) Unplug and DROP PDB(pdb1)

2 – Configure TDE Destination CDB(cdb2)

F) PLUG PDB(pdb2) using Unplugged pdb1

G) IMPORT KEY from Source PDB(pdb1) to Destination PDB(pdb2)

H) Validate PDB is fully integrated with CDB2

I hope this helps you!!!
