In a Oracle 12c multitenant DB instance with multiple PDBs, is it possible to enable ARCHIVELOG mode on a single PDB?

  • ,Yes. but You must do this from the root container. Commented Feb 28, 2017 at 11:14
  • For root container do you refer to CDB? In this way all PDBs will be affected, isn't it?

  • Yes. On a single PDB not affecting others...

Because all PDBs share the same redo log files, it's not possible to enable archive log mode only for a specific PDB. All PDBs share the archive log mode of the CDB.

Remember, the PDBs themselves don't have any instance (processes and memory areas) or control file and redo logs

  • I came to your own conclusion after looking at this link but not having found explicit in oracle documentation I was left with the doubt.
