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

———- ———- ———- ———- ——————————– —————————— ———- — ————————————————————————— ———- ———- ———- ——– ———————-

         1         13  168895093  168895093 8837DFB294B8214DE054020820D8D4F1 PDBTEST                        READ WRITE NO  06-MAY-19 02.03.32.098 PM +02:00                                            8042252890  907018240       8192 ENABLED                       0

         2         13  168895093  168895093 8837DFB294B8214DE054020820D8D4F1 PDBTEST                        READ WRITE NO  06-MAY-19 02.04.32.119 PM +02:00                                            8042252890  907018240       8192 ENABLED                       0

 

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

———- ———- ———- ———- ——————————– —————————— ———- — ————————————————————————— ———- ———- ———- ——– ———————-

         1         13  168895093  168895093 8837DFB294B8214DE054020820D8D4F1 PDBTEST                        MOUNTED        06-MAY-19 02.06.27.877 PM +02:00                                            8042252890  907018240       8192 ENABLED                       0

         2         13  168895093  168895093 8837DFB294B8214DE054020820D8D4F1 PDBTEST                        MOUNTED        06-MAY-19 02.06.28.166 PM +02:00                                            8042252890  907018240       8192 ENABLED                       0

 

4.) open the Database in Just on Node in READ ONLY MODE:

 

SQL>  alter pluggable database pdbtest open read only;

 

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

CLOUD:

 

5.) Create the TNS Entry on the TNSNAMES.ORA 

 

PDBTEST =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.165.13)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = PDBTEST)

    )

  )

 

[oracle@vits-racdb1 admin]$ tnsping pdbtest

6.) Create a database link from CLOUD Database to ON-Premise:

 

create public database link lnk_PDBTEST connect to c##_link identified by link001# using ‘PDBTEST’;

 

SQL> select * from v$pdbs@lnk_PDBTEST;

 

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

7.) Create the new PDB on the Oracle Cloud:

 

SQL> show parameter tables

 

NAME                                 TYPE        VALUE

———————————— ———– ——————————

encrypt_new_tablespaces              string      DDL

         5 PITBITBUCKET01                 READ WRITE NO

         6 PDBTEST                        MIGRATE    YES

 

8.) Check the violations

 

*** In case of errors with APEX

cd /u01/oracle/product/12.1.0/dbhome_1/apex

CDB’s version 12.2.0.1.0.                          PENDING   Either upgrade the PDB or reload the components in the PDB.                               6

 

9.) Upgrade the PDB:

 

cd $ORACLE_HOME/rdbms/admin

$ORACLE_HOME/perl/bin/perl catctl.pl -c ‘PDBTEST’ catupgrd.sql

 

sqlplus / as sysdba

 

SQL> show pdbs

         5 PITBITBUCKET01                 READ WRITE NO

         6 PDBTEST                        READ WRITE YES

 

exit;

 

10.) Apply Datapatch

 

cd $ORACLE_HOME/OPatch

 

./datapatch -verbose -pdbs PDBTEST

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
