noncdb_to_pdb.sql – why does it take so long?

What is noncdb_to_pdb.sql?

noncdb_to_pdb.sql - Why does it take so long?The script noncdb_to_pdb.sql gets run only once in the life span of your database. It gets executed when a regular Oracle database (non-CDB) gets move to become part of a Single-/Multitenant deployment as a pluggable database (PDB). But why does it take so long?

You will never run this script again for this database.… [Read More]

Upgrade Everything at Once – Multitenant Upgrade from Oracle 12.1 to 12.2

I did blog about this topic a while back.

Upgrade PDBs – Everything At Once (Full CDB Upgrade)

Theory is nice but it’s a big difference when you do it the first time with a non-lab deployment at a customer with a real Multitenant database with almost 100 PDBs.Then you learn that neither the documentation nor my previous blog post contain all the necessary steps.… [Read More]

DBMS_QOPATCH does not work in PDBs (right now)

Thanks to Murthy who commented on this blog post and Jeannette Holland (SimCorp) who opened an SR resulting in an ER.

DBMS_QOPATCH in Multitenant

DBMS_QOPATCH will deliver useful information about installed patches only when executed within the CDB$ROOT. It has been designed this way for security reasons in Oracle Database 12.1 but I can easily see a need to check for installed patches within a PDB as well.… [Read More]

Create Container Databases (CDB) with less options – it’s now supported in Oracle

When Oracle Multitenant was launched Roy and I amongst many other people always mentioned that the requirement of having all options in a Container Database (CDB$ROOT), and therefore also for the PDB$SEED with the immediate result that all PDBs provisioned from the PDB$SEED will have all options as well, will hinder customer adoption¬†significantly.… [Read More]
