Plug and unplug PDB on the Cloud

You can use DBaaS Monitor to plug/Unplug in a pluggable database.


  • Open Dbaas Monitor like usual 


  • Once you did this the, you will redirected to new page, in my case i have 2 PDB let's choose one of them and try to unplug it then Plug it again.

  • From the Right Panel press on the Unplug new screen will be open, As you see from the below picture you should the XML path in your mind in case you need to Plug the database again , put the password same as you use it when you create PDB.



The output should be "PDB unplugged successfully"..


Let's Plug again.

Enable master key Encryption Key for a PDB on the cloud

SELECT wrl_parameter, status, wallet_type FROM v$encryption_wallet;Master Key Encryption allow you to encrypt sensitive data, such as credit card numbers, stored in table columns. Encrypted data is transparently decrypted for a database user who has access to the data. Transparent data encryption helps protect data stored on media in the event that the storage media or data file gets stolen for more information about it here.

After creating Database on the cloud ( Dbaas ) you can enable the master key by using the below steps :-


  • First of all you need to check the name of the container that you want to enable master key.
    • select con_id, dbid, name from v$pdbs;

  • as you see my container name is PDB1 set the session to this.
    • ALTER SESSION SET CONTAINER = PDB1;

  • Check the location for the wallet by running the below query :-
    • SELECT wrl_parameter, status, wallet_type FROM v$encryption_wallet;

  • Back to Root Container run the below query to see the wallet parameter type there is two value autologin or password each one of them having it's own usage, in my case the value set to password.

  • Now i should close the wallet depend on the wallet type in my case it's set as password then i will use the below  for more information about ADMINISTER KEY MANAGEMENT here
    • ADMINISTER KEY MANAGEMENT SET KEYSTORE close IDENTIFIED BY Mypassword;

  • When i tried to open the wallet using the same password i set it before. 
    • ADMINISTER KEY MANAGEMENT SET KEYSTORE open IDENTIFIED BY MyPassword CONTAINER=all

But my wallet is closed, i found oracle support document here Document number 1944507.1 which discuss this error and provide a solution for this error you can back to this document.

Once you apply the solution you will be able to open the wallet as below.






Welcome to TDE on the cloud.

Enable-Disable Database Vault on the Cloud

Oracle Database Vault restricts access to specific areas in an Oracle database from any user, including users who have administrative access. For example, you can restrict administrative access to employee salaries, customer medical records, or other sensitive information. for more information about it here

Now to enable DBV on the cloud it's very simple all you have to do is the following :-

  • Connect to the compute node as oracle user using putty i post about this before.
  • To enable DBV Run the below command :-
    • dbaascli dv on

  • After this the output should like this "Successfully configured DV"
Congratulation DBV is enabled now.

And to Disable DBV All you have to do is Run :-

  • dbaascli dv off


Enjoy the Cloud , Cheers,
Osama Mustafa

Notes :-
  1. For the username i put C## because i am using database 12cR1 and enable pluggable..
