DML replication from source GG to Target GG on pluggable database 19c
Container source database : sourcegg1
source pdb name : sgg1
Container Target database : targetgg1
target pdb name : tgg1
Golden gate version : 19c linux on both source and target
oracle database version : 19c on both source and target
source container schema name : c##ggsource
target container schema name : c##ggtarget
Source ggci scapture process exint and datapump process is dpint
Target ggsci replicate process repint
Source hostname: srv6.example.com
Target hostname : srv7.example.com
- Enable replication parameter on source database sourcegg1
SQL> alter system set enable_goldengate_replication=TRUE;

- Create common user and grant dba privilege to all pdb or we can give privilege to specific pdb as well
SQL> grant dba to c##ggtarget container=all;
Grant succeeded.
- Connect to source GG and create extract and datapump values for replication
