Primary not able to connect to standby database, no RFS process started on standby database.
Alert log on primary has ORA 1017 errors and trace file has ORA-16047
ORA-16047: DGID mismatch between destination setting and target database
Recreated the password file on primary and copied to standby database, but still primary LNS not able to communicate to RFS on standby
select process, status from v$managed_standby; — RFS not started on DR database
I am able to connect to standby database using sqlplus with the recreated password file.
LOG_ARCHIVE_CONFIG parameter is missing from standby database , though password file is fine , primary not able to authenticate the DR DB unique_name as the LOG_ARCHIVE_CONFIG is missing.
alter system set log_archive_config=’DG_CONFIG=(primary,DR)’ scope=both
Above parameter setting resolved the issue.
