An action could be sending an email notification or executing a function to implement post-creation tasks like creating users. If…
Introduction We already talked about remote PDB cloning in Data Guard environments in previous blog posts. As the datafiles of the cloned PDB are not present on the standby database, there are several manual steps to be followed to create the PDB on the standby site in 19c: Using Transient no-standby PDB. Using STANDBYS=NONE followed…
Introduction Oracle Multitenant is integrated with Oracle Data Guard. Data Guard is configured at the CDB level and will replicate all transactions from the primary to the standby for all PDBs in a single stream, including creating and deleting PDBs. But! When we create a new PDB, which is a clone from PDB$SEED, or create…
