Not all PDBs backedup during CDB$ROOT backup
Greetings and salutations,
Oracle Cloud (classic) is still new to me.
Luckily rman still provides answeres.
The backup is scheduled in /etc/crontab using "bkup_api bkup_start --dbname=<dbname>
This database contains 23 PDBs plus the PDB$SEED.
The 3 latest created PDBs only have archivelog backups, but no full nor incrementals.
$ORACLE_HOME/dbs/opcSID.ora files contains the parameter OPC_CONTAINER.
This parameter has now 1 value. dbcs-<dbname>
Can this parameter have more than 1 value?
There don't seem to be errors in the alert.log about backup failures.
What could be the reason these last 3 added PDBs are not backed-up during full database backup?
