Alex's question is still valid. Here's the example from the Data Guard Concepts manual of how your primary needs to be configured (chicago is the primary, boston is the standby): DB_NAME=chicago DB_UNIQUE_NAME=chicago LOG_ARCHIVE_CONFIG='DG_CONFIG=(chicago,boston)' CONTROL_FILES='/arch1/chicago/control1.ctl', '/arch2/chicago/control2.ctl' LOG_ARCHIVE_DEST_1= 'LOCATION=/arch1/chicago/ VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=chicago' LOG_ARCHIVE_DEST_2= 'SERVICE=boston LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=boston' LOG_ARCHIVE_DEST_STATE_1=ENABLE LOG_ARCHIVE_DEST_STATE_2=ENABLE You need to have configured standby redo logs as well. What does the alert log on the primary show you? On Mon, Jan 5, 2009 at 11:01 AM, dba1 mcc <mccdba1@xxxxxxxxx> wrote: > "Archive log" transfer from Primary DB to standby DB is correct.
