Amsterdam DBA notes: Migrate noncdb to pdb oracle12c

First via dbca we need to create our non CDB database:

[oracle@ora12c66 ~]$ cat /vagrant/dbca_noncdb.rsp

OPERATION_TYPE = "createDatabase"

[CREATEDATABASE]

RESPONSEFILE_VERSION = "11.2.0"

OPERATION_TYPE = "createDatabase"

GDBNAME = "orcl12c"

SID = "orcl12c"

TEMPLATENAME = "General_Purpose.dbc"

SYSPASSWORD = "qwe123"

SYSTEMPASSWORD = "qwe123"

SYSMANPASSWORD = "qwe123"

DBSNMPPASSWORD = "qwe123"

CHARACTERSET = "UTF8"

NATIONALCHARACTERSET= "UTF8"

[oracle@ora12c66 ~]$ dbca -silent -createDatabase -responseFile /vagrant/dbca_noncdb.rsp

there is a new service registered with the listener:

[oracle@ora12c66 ~]$ lsnrctl status

The command completed successfully

and we can see the new datafiles

[oracle@ora12c66 ~]$ tree /u01/oradata/

and it is registered in /etc/oratab

[oracle@ora12c66 ~]$ tail -5 /etc/oratab

# Multiple entries with the same $ORACLE_SID are not allowed.

cdborcl:/u01/product/12.1.0/db_1:N

orcl12c:/u01/product/12.1.0/db_1:N

before I start the migration, lets put a custom user/table:

SQL> select name from v$database;

NAME

---------

ORCL12C

SQL> show con_name

CON_NAME

------------------------------

Non Consolidated

SQL> create user dave identified by qwe123;

User created.

SQL> create table dave.test_table(col1 varchar2(30));

Table created.

SQL> desc dave.test_table

Name Null? Type

----------------------------------------- -------- ----------------------------

COL1 VARCHAR2(30)

so now I can start the migration :)

I am following oracle-base instructions: http://oracle-base.com/articles/12c/multitenant-migrate-non-cdb-to-pdb-12cr1.php

and I start by opening the database to be migrated in read only and generating the PDB xml file

SQL> SHUTDOWN IMMEDIATE;

Database closed.

Database dismounted.

ORACLE instance shut down.

SQL> STARTUP OPEN READ ONLY;

ORACLE instance started.

Total System Global Area 588746752 bytes

Fixed Size 2291040 bytes

Variable Size 268438176 bytes

Database Buffers 314572800 bytes

Redo Buffers 3444736 bytes

Database mounted.

Database opened.

SQL>

BEGIN

DBMS_PDB.DESCRIBE(

pdb_descr_file => '/tmp/ORCL12C.xml');

END;

PL/SQL procedure successfully completed.

now lets shutdown the database to be migrated

SQL> shutdown

Database closed.

Database dismounted.

ORACLE instance shut down.

SQL> exit

Disconnected from Oracle Database 12c Enterprise Edition Release 12.1.0.1.0 - 64bit Production

With the Partitioning, OLAP, Advanced Analytics and Real Application Testing options

[oracle@ora12c66 ~]$

You might want to inspect the xml file, it is mostly tablespace details, database options, init.ora parameters, timezone version data:

<?xml version="1.0" encoding="UTF-8"?>

<PDB>

<name>SYSTEM</name>

<file>

<path>/u01/oradata/orcl12c/system01.dbf</path>

</parameters>

<tzver>primary version:18</tzver>

<tzver>secondary version:0</tzver>

</tzvers>

</optional>

</PDB>

any way we can now create pdb3 based on the ora12c (non-container managed) database

SQL> CREATE PLUGGABLE DATABASE pdb3 using '/tmp/ORCL12C.xml' copy FILE_NAME_CONVERT = ('/u01/oradata/orcl12c/','/u01/oradata/cdborcl/pdb3/');

Pluggable database created.

although we can't connect yet:

SQL> conn system/qwe123@ora12c66/pdb3

ERROR:

ORA-01033: ORACLE initialization or shutdown in progress

Process ID: 0

Session ID: 0 Serial number: 0

Warning: You are no longer connected to ORACLE.

first we need to run the noncdb_to_pdb.sql :

SQL> conn / as sysdba

Connected.

SQL> ALTER SESSION SET CONTAINER=pdb3;

Session altered.

SQL> @$ORACLE_HOME/rdbms/admin/noncdb_to_pdb.sql

...

on my smallish virtual machine, this script takes a long time (especially the utl_recomp.recomp_parallel(threads) step); but once it is done we can open the new pdb3 database and see the dave.test_table marker object we created on the original non-container manager database

SQL> ALTER PLUGGABLE DATABASE OPEN;

Pluggable database altered.

SQL> conn system/qwe123@ora12c66/pdb3

Connected.

SQL> desc dave.test_table

Name Null? Type

----------------------------------------- -------- ----------------------------

COL1 VARCHAR2(30)

Lastly let's cleanup the noncdb orcl12c database:

[oracle@ora12c66 ~]$ dbca -silent -deleteDatabase -templateName New_Database.dbt -sourceDB orcl12c -sysDBAUserName qwe123 -sysDBAPassword qwe123
