How to create a PDB from a Non-CDB using
DBMS_PDB package
To test this scenario I have recently created using DBCA a non container database
named ORCL. CDB001 and CDBTEST are instead two container databases.
view plainprint?
1. [oracle@vsi08devpom ~]$ ps -ef|grep smon
2. oracle 4081 1 0 Jul15 ? 00:01:30 ora_smon_CDB001
3. oracle 11394 1 0 10:20 ? 00:00:00 ora_smon_ORCL
4. oracle 12586 9609 0 10:46 pts/0 00:00:00 grep smon
5. oracle 16455 1 0 Jul17 ? 00:01:34 ora_smon_CDBTEST
I want to consolidate this database plugging it into a container database.
In this scenario I'm going to use the DBMS_PDB package to create the XML file
with the metadata of ORCL database.
Before using the DBMS_PDB.DESCRIBE procedure, the ORCL database needs
to be in READ ONLY mode.

Now connect to the container database. In my case I want to plug ORCL database
into the CDBTEST container. It currently contains 4 pluggable databases.

Here is the situation of the directories for the CDBTEST container database:
view plainprint?
1. [oracle@vsi08devpom ~]$ cd /opt/app/oracle/oradata/CDBTEST/
2. [oracle@vsi08devpom CDBTEST]$ ll

Now you can plug the ORCL database into the CDBTEST container database using
the usual syntax (have a look at this post)
view plainprint?
1. SQL@CDBTEST> create pluggable database ORCL using '/opt/app/oracle/oradata/orcl.xml' copy file_name_convert=('/opt/app/oracle/oradata/ORCL','/opt/app/oracle/oradata/CDBTEST/ORCL');
2.
3. Pluggable database created.
The Oracle software copies under the directory
/opt/app/oracle/oradata/CDBTEST/ORCL all the datafiles coming from
/opt/app/oracle/oradata/ORCL location.

A new pluggable database is created with a NEW status
view plainprint?
1. SQL@CDBTEST> select pdb_id, pdb_name, dbid, status, creation_scn, con_id from CDB_PDBS;
2.
3. PDB_ID PDB_NAME DBID STATUS CREATION_SCN CON_ID
4. ---------- ---------- ---------- ------------- ------------ ----------
5. 2 PDB$SEED 4063610283 NORMAL 217 1

7. 4 PDBTEST2 2395404598 NORMAL 1548944 1
8. 5 PDBTEST3 2434165039 NORMAL 1550036 1
9. 6 PDB003 1448206714 NORMAL 2744910 1
10. 7 ORCL 1350603571 NEW 3226095 1
It's still not the time to open the new PDB.
You need first to execute, while connected to the new pluggable database, the
script $ORACLE_HOME/rdbms/admin/noncdb_to_pdb.sql:
view plainprint?
1. [oracle@vsi08devpom CDBTEST]$ ll /opt/app/oracle/product/12.1.0/db_1/rdbms/admin/noncdb_to_pdb.sql
2. -rw-r--r--
1 oracle oinstall 19191 Apr 15 22:27 /opt/app/oracle/product/12.1.0/db_1/rdbms/admin/noncdb_to_pdb.sql
3.
4. SQL@CDBTEST> alter session set container=ORCL;
5.
6. Session altered.
7.
8. SQL@CDBTEST> @/opt/app/oracle/product/12.1.0/db_1/rdbms/admin/noncdb_to_pdb.sql
9. SQL@CDBTEST> SET SERVEROUTPUT ON
10. SQL@CDBTEST> SET FEEDBACK 1
11. SQL@CDBTEST> SET NUMWIDTH 10
12. ...
13. ...
14. ...
15. SQL@CDBTEST> --
leave the PDB in the same state it was when we started
16. SQL@CDBTEST> BEGIN
17. 2 execute immediate '&open_sql &restricted_state';
18. 3 EXCEPTION
19. 4 WHEN OTHERS THEN
20. 5 BEGIN
21. 6 IF (sqlcode <> -900) THEN
22. 7 RAISE;
23. 8 END IF;
24. 9 END;
25. 10 END;
26. 11 /
27.
28. PL/SQL procedure successfully completed.
29.
30. SQL@CDBTEST>
31. SQL@CDBTEST> WHENEVER SQLERROR CONTINUE;
32. SQL@CDBTEST>
Now you can open the new ORCL pluggable database.
view plainprint?
1. SQL@CDBTEST> show con_name;
2.

3. 3. CON_NAME
4. ------------------------------
5. ORCL
6. SQL@CDBTEST> alter database open;
7.
8. Database altered.
The database is so available and ready to be used.
view plainprint?
1. SQL@CDBTEST> select pdb_id, pdb_name, dbid, status, creation_scn, con_id from CDB_PDBS;
2.
3. PDB_ID PDB_NAME DBID STATUS CREATION_SCN CON_ID
4. ---------- ---------- ---------- ------------- ------------ ----------
5. 2 PDB$SEED 4063610283 NORMAL 217 1

9. 6 PDB003 1448206714 NORMAL 2744910 1
10. 7 ORCL 1350603571 NORMAL 3226095 1
That's all.
