Oracle Data Guard RFS not starting on standby – trouble shooting data guard background processes – or archivelog not being sent / transported to standby:
Everything was basic setup correctly but archivelog was not playing to the standby. Standby creation went fine.
I did make a change to the log_archive_dest_3 that was being used for standby transmission. The fix:
After changing LOG_ARCHIVE_DEST_3. Toggle LOG_ARCHIVE_DEST_STATE_3 to defer and back to enable as follows:
alter system set LOG_ARCHIVE_DEST_STATE_3=defer scope=both;
alter system set LOG_ARCHIVE_DEST_STATE_3=enable scope=both;
