V10.2.0.1 RHEL5 I was using *Note:387339.1 I am close but not home free yet. From alert log Fri Aug 15 10:50:02 2008 ALTER SYSTEM SET log_archive_config='dg_config=(rac03_ora1d,ora1d)' SCOPE=BOTH; Fri Aug 15 10:52:02 2008 Errors in file /u01/orasys/orcl/admin/ora1d/bdump/ora1d1_arc0_17722.trc: ORA-16057: DGID from server not in Data Guard configuration Fri Aug 15 10:52:02 2008 PING[ARC0]: Heartbeat failed to connect to standby 'RAC03_ORA1D'.

I see the above but nothing I have changed has made any difference. 1) Exactly how do I obtain the "DGID" of the primary. 2) Where on the secondary must this value be deposited? A Google search showed somebody else had this but no solution was ever posted. Any clues would be most welcomed. TIA *
