Environment Details
Parameters needs to configure both side for Data guard,
Primary side:
db_name:- Same name for all primary and standby database
db_unique_name:-a unique db name to uniquely identify primary and standby db because db_name is same
Log_archive_dest_1:-local archive destination
Log_archive_dest_2:-destination for standby database
Standby_file_management:-automatically create file at standby db site
Standby Side:
db_unique_name:-it has to be different from DB_NAME parameter
db_file_name_convert:-specify the path name and datafile location of primary database datafile followed by standby location
log_file_name_convert:-specify the path name and redo logfile location of primary database redo logfile followed by standby location
log_archive_dest_1:-location of archives coming from primary database
fal_server:-to fetch archived log from primary site when log gap is detected at standby site.The parameter value is tns service name
fal_client:- to copies missing archive to standby database
High Level Steps:- Step 1:-Check FORCE LOGGING is enabled Step 2:- Make sure primary is in archivelog mode Step 3:- PFILE creation and copy to standby database Step 4:-Edit the parameters and directories in created pfile Step 5:- Parameters for primary database Step 6:- Copy password file from primary to standby server Step 7:- Make the respective directories for standby database Step 8:- Keep the database in NOMOUNT stage to create standby database Step 9:- Create spfile for standby database Step 10:- Listener and TNS Configuration Step 11:-Start the listener in Standby database and check the status Step 12:-In standby side,check RMAN connection.Connect primary database as TARGET and standby database as AUXILIARY(creating new instance) Step 13:-Active Duplication for creating standby database Step 14:- Post check status for Standby database Step 15:- Enable the recovery(MRP Process) Step 16:- Check the Standby database sync status with primary
