Oracle Multitenant enables an Oracle Database to function as a container database (CDB). A CDB consolidates multiple pluggable databases (PDB), a portable collection of schemas, schema objects, and non-schema objects. Whether deployed on-premises or in the cloud, with Oracle Multitenant, applications run unchanged in self-contained PDBs, improving resource utilization, management, and overall security.
My customer met an issue that is they did not want to patch all pdbs together. For example, 4 nodes RAC, pdb1 runs on node1, pdb2-4 on other nodes, pdb1 met a bug, must apply patch immediately. They only could apply for a maintain window for pdb1 to stop. But in multitenant, we have to patch all pdbs on all nodes together. Or let node1 has different patchs with other nodes, we don't dare to do that, shall we ???
Oracle database 19c with container mode is not certified with Oracle EBS 12.x.x version. Can we create multiple PDBs in this environment?
Do you know what the market share is (ball park figure fine) for Oracle 18c and 19c.
1. Non-CDB.
2. Single tenant.
3. Multitenant for Europe including the UK, for Oracle? Thanks.
2:10 and also you have way more fckd up installation process, that requires you to spend 6 hours on doing PhD on Oracle databases installation, because all the pgbd pluggable databases and others get messed up and confused
I'm mad at that installation process, but anyway, this presentation is very nice and clear xD
Can we use the licenses of on-premises databases for switching over to cloud? Please provide modalities.
Good question, contact your licenese account manager for the same. I am no expert with licensing,it's known as BYOL (Bring your own license) to the cloud.

Please contact your sales rep or sales engineer for any further questions
Can CDBs run on a RAC configuration on Exadata?
And are the Redos separate for each PDB or is it on the CDB level. ?
Yes, CDB can run on RAC configuration on Exadata. Redo is at the CDB level
Is there any option that each pdb have a different NLS
Character Set?
Hope this helps, Asif: docs.oracle.com/en/database/oracle/oracle-database/19/multi/overview-of-the-multitenant-architecture.html#GUID-7F629DD8-D4DE-4FD7-9C35-38AC016DDCDC

pdbs must have same Character Set
Oracle DB has reached saturation. There's nothing exciting in the newer versions. But their presence in Cloud & all, isn't up to the mark- cannot compete with contemporaries. Easy behind in the race.
