In the past I wrote some articles about cloning PDBs to new environments. And I added a post about RELOCATE as well. But I realized that I have no specific blog post about a very typical scenario: Upgrade Testing – Online Clone a PDB to 19c.

My Setup
I have an Oracle 12.2.0.1 CDB with a PDB, and another Oracle 19.6.0 CDB. I will hot clone the PDB from 12.2.0.1 to the higher version CDB, and then upgrade the PDB.
The motivation to do it this way is to allow testing for the application teams within my test environment being already on 19.6.0. As soon as AutoUpgrade supports this scenarios as well, you can automate this every night.
Hot Cloning
You can use Hot Cloning since the introduction of Local Undo with Oracle 12.2.0.1. Hence, if my source is at least Oracle 12.2.0.1 and if I use the default, Local Undo, this works. As usual, I show the sequence of actions:
| CDB1 | CDB2 |
Create a common user for the relocate operation and assign necessary privileges:
CREATE USER c##borg IDENTIFIED BY oracle DEFAULT TABLESPACE users TEMPORARY TABLESPACE temp CONTAINER=ALL; GRANT CREATE SESSION, CREATE PLUGGABLE DATABASE, SYSOPER TO c##borg CONTAINER = ALL; |
|
Create the public database link for the relocate operation:
CREATE public DATABASE link clonemypdb CONNECT TO c##borg IDENTIFIED BY oracle USING 'CDB1'; |
|
Initiate the relocation:
CREATE PLUGGABLE DATABASE PDB1 FROM PDB1@clonemypdb file_name_convert=('CDB1','CDB2');
|
|
Open the PDB:
ALTER PLUGGABLE DATABASE PDB1 OPEN UPGRADE; The PDB will open with errors in RESTRICTED mode only. |
Then I need to open PDB1 in CDB2 in UPGRADE mode because its dictionary is still an Oracle 12.2.0.1 dictionary whereas it operates now within a 19c database.
I need to upgrade it.
Upgrade of the PDB
This step is simple as I just avoid the preupgrade step. In my environment there are no extra tasks necessary for PDB1 before upgrading it.
Invoke the upgrade in the CDB2 environment:
$ dbupgrade -c "PDB1" -l /home/oracle/logs

Hi Mike, great approach – any chance you have an idea when AutoUgrade will support this?
Hi Jeannette,
thanks – and unfortunately there are a lot of open projects we are working on right now (e.g. “Unplug/plug/upgrade”). I fear, using an online clone for testing isn’t on the list right now. But I will carry it forward to the team for sure.
Thanks and kind regards – and take care please!
Mike
Thanks for your answer Mike. We are working with a business scenario where this method could also apply to production upgrades (of which we have 100s). We have a fallback scenario which is broken if we unplug/plug/upgrade. This is where the online clone option comes in handy. This is our pitched scenario:
1. Run AutoUpgrade analyse for PDBx in CDBoldVersion and fix issues reported for PDBx
2. Clone PDBx over database link to PDBy in CDBnewVersion and start PDBy in upgrade mode
3. Run AutoUpgrade on PDBy in CDBnewVersion
4. Any errors in step 2 or 4, open op for continued work in PDBx, else drop PDBx
5. If no errors open op for continued work in PDBy
Kind regards and take care as well !
Hi Jeannette,
you are the 2nd one proposing this as the better scenario (online clone instead of relocate), and I agree with you.
Especially the fact that the relocate – as soon as you start the relocated PDB in STARTUP UPGRADE mode – drops the source whereas the clone leaves the source makes it the better solution.
Thanks for your suggestion.
And please take care, too!!! And enjoy the Easter weekend!
Cheers,
Mike
Hi Mike,
in the real world Data Guard is often used. The 19c therefore already has one standby db and no Active Data Guard is used. Do you have already plans for such an article?
Frank
Hi Frank,
at the moment not – there are so many different topics on my list right now … I will blog more about DG once AutoUpgrade fully handles everything.
Cheers,
Mike
Hello Mike,
Very useful demo. Can you have a similar clone for CDB1 PDB1 which has TDE wallet enable on Oracle 12.2 and clone to CDB2 on Oracle 19c.
Thank you
Hi Emma,
working on it.
Example:
create pluggable database DEV from DEV@clone_link file_name_convert=(‘CDB1’, ‘CDB2’) KEYSTORE IDENTIFIED BY *********;
Cheers,
MIke
Mike,
Thanks for the detailed steps. I ran into Bug 29469563 cloning database(target 19.7) on OCI with TDE. After applying the patch it ran fine.
Regards
Sri
Thanks Sri!
Cheers,
Mike
Hi Mike , will this work from version 12.1 to 19.7 ?
Regards,
RP
Unfortunately not as 12.1 does not support refreshable PDBs. This is a feature which is based on Local Undo and some other things which aren’t simply there in 12.1.0.2 yet.
Cheers,
Mike
Outstanding!
Hello Mike,
Is there a way to clone and upgrade a PDB as you describe without breaking the standby (active dataguard) db? We would like to upgrade our PDBs with a clone, as it is very fast and the original DB remains untouched. But I could not yet find a way without destroying the standby.
Cheers, Dagmar
Hi Dagmar,
please give me more insights. What exact steps are you doing, and why does it break the standby?
Thanks,
Mike
very nice!
Hello Mike,
Our setup: Several multitenant databases, 2 node RAC, active Dataguard on 2 Eighth Exadatas, 18c. We want to migrate the PDBs one by one to 19c. Old PDBs should remain untouched for fallback. I built 19.9 CDBs and tried to clone two ways:
1a.) Clone pdb via dblink
————————————————-
https://oracle-base.com/articles/18c/multitenant-copying-a-pdb-in-a-data-guard-environment-18c
—> Disadvantage: source in read only, downtime
Source Primary
CREATE USER c##remote_clone_user
open PDB in read only
Target Standby
ALTER SYSTEM SET STANDBY_PDB_SOURCE_FILE_DBLINK=’clone_link’ scope=memory sid=’*’;
Target Primary
CREATE DATABASE LINK clone_link
CREATE PLUGGABLE DATABASE new FROM sourcepdb@clone_link;
or 1b.) Clone pdb via rman ‘FROM ACTIVE DATABASE’
————————————————-
https://apex.oracle.com/pls/apex/germancommunities/dbacommunity/tipp/7001/index.html
rman> DUPLICATE PLUGGABLE DATABASE ‘soure pdb’ as new TO ‘targetcdb’ FROM ACTIVE DATABASE;
—> Advantage: source needn’t be in read only
—> PDB was in unintentionally in refesh mode and I could neither refresh nor switch refresh mode off.
2.) Upgrade pdb to 19c
————————————————-
https://mikedietrichde.com/2020/03/06/upgrade-testing-online-clone-a-pdb-to-19c/
Target Primary
dbupgrade -c “new” -l /logdir
timezone adjustment
===> Standby broken!
I tried to switch apply off before clone and also before upgrade, no difference.
Has anybody tried this approach yet? In theory, should the standby remain intact?
Then I probably do something wrong.
Regards, Dagmar
Hi Dagmar,
I don’t think that the PDB needs to be in read-only mode. The original MOS note Tim is referring to has this line:
“The source PDB must be in Read Only mode and remain for the duration of the copies to the primary and all standby databases in the configuration. We do not at this time support automatic maintenance of the standby database of any type with the 12.2 hot cloning or relocate features.”
And I’m in doubt if that is true. Let me check this.
And regarding 2), I wonder why the DG team is not aware of such trouble. Let me check this as well.
Cheers,
Mike
I performed the procedure and it worked flawlessly. How do I change the compatible parameter for the cloned PDB?
SYS@cdb19c:SQL> show parameters compatible;
NAME TYPE VALUE
———————————— ———– ——————————
compatible string 19.0.0
noncdb_compatible boolean FALSE
@:SQL> connect system/oracle_4U@ocmpdb;
Connected.
SYSTEM@ocmpdb:SQL> show parameters compatible;
NAME TYPE VALUE
———————————— ———– ——————————
compatible string 12.2.0
noncdb_compatible boolean FALSE
Hi David,
the PDB adopts always the COMPATIBLE of the CDB$ROOT.
And to change it in the root, you need to restart the database with all PDBs.
Cheers,
Mike
Hi Mike
When running the “create pluggable database” step, I’m receiving this error, even though Oracle Label Security and Oracle Database Vault are NOT installed on either the source or target CDB (and all parameters in v$option have a con_id =0):
ERROR at line 1:
ORA-65346: The PDB version is lower and components (DV, OLS) are missing in CDB.
I am upgrading a 12.2.0.1 PDB to 19c, just like you showed. Have you seen this before?
Thanks,
Topher
Hi Topher,

Mike, trying to follow this but when doing the create pluggable database I am getting

Hi Mark,
I fear you may need to open an SR please 🙁
