I have version 18.3 and I have container database ORCLCDB with single PDB pdb1.
I'm using dbca for create local standby database.
./dbca -silent -createDuplicateDB -gdbName ORCLCDB -sid ORCLCLON -sysPassword ****-primaryDBConnectionString ORCLCDB -createAsStandby -initParams sga_target=1024M -dbUniqueName ORCLCLON -datafileDestination "/opt/oracle/oradata/ORCLCLON"
It finishes without issue, however had problem with pdb as it seems it points to the same location causing primary pbd completly useless.
1) Is there any way to clone cdb$root only?
2) Is it possible to disable cloning for pdb (I cannot find alter plugabble database .. standby = none command in docuementation).
1) You can RMAN method.
Ex:- backup database root;
2) You can use backup pluggable database
Ex:- BACKUP PLUGGABLE DATABASE hrpdb, salespdb, invpdb;
