setting up 10g physical standby database

STEPS for creating 10g dataguard

prerequisite : 9i dataguard setup knowledge

Step1 : Prepare initSID.ora file for primary and standby databases as follow.

** STANDBY setup parameters are given in bold and highlighted

STEP 2:

part A)

shutdown primary database cleanly and copy datafiles to standby location.

Part B) create standby controlfile by giving following command at production database at mount stage

alter databse create standby controlfiel as 'location\filename' ;

move this generated file to standby controlfile location as pointed by standby initSID.ora file

step 3)
create oracle service and password file with the same password at standby database location

step 4)
prepare the TNSNAMES.ORA and LISTENER.ora at both production and standy locations.

To check archive log gap

SELECT * FROM (
SELECT sequence#, archived, applied,
TO_CHAR(completion_time, 'RRRR/MM/DD HH24:MI') AS completed
FROM sys.v$archived_log
ORDER BY sequence# DESC)
WHERE ROWNUM <= 10
