Tasks must perform on PRIMARY :

On Primary site

1. Install oracle
2. Create database by dbca
3. Create archivelog location
4. Turn on force logging on primary database:

ALTER DATABASE FORCE LOGGING;

select * from v$pwfile_users;

select bytes from v$log;

select group#, member from v$logfile;

5. Adding standby redo log group.

ALTER DATABASE ADD STANDBY LOGFILE GROUP 5(‘DATAFILE_LOCATION/ULTIMUS/redo07.log’) SIZE 100M;

ALTER DATABASE ADD STANDBY LOGFILE GROUP 6 (‘DATAFILE_LOCATION/ULTIMUS/redo08.log’)SIZE 100M;

ALTER DATABASE ADD STANDBY LOGFILE GROUP 7 ('DATAFILE_LOCATION/ULTIMUS/redo09.log')SIZE 100M;

select * from v$standby_log;


6. shutdown immediate;
7. startup mount;
8. alter database archivelog;
9. alter database open;
    archive log list;
10. startup mount;

11. Create standby control file and transfer it to Standby.
alter database create standby controlfile as ‘DATAFILE_LOCATION/ULTIMUS/STAN.ctl’;
12. ALTER DATABASE OPEN;
13. Recheck init file,tnsname,listener file.
14. create spfile.
15. start listener
16. tnsping
17. shutdown




 Init file in standby server

 On standby site

1. install oracle
2. create database by dbca,
3. shutdown.delete datafile
3. create archivelog location
4. copy datafile,tnsname.ora,lIstener.ora
5. delete control file except standby,delete standby redo file
5. recheck pfile.
6. startup mount pfile
OR. startup   mount pfile='$ORACLE_HOME/dbs/initSTAN.ora'

7. if necessary:

ALTER DATABASE DROP LOGFILE GROUP 5;
ALTER DATABASE DROP LOGFILE GROUP 6;
ALTER DATABASE DROP LOGFILE GROUP 7;

8. Add stanby redo log group:

ALTER DATABASE ADD STANDBY LOGFILE GROUP 5(‘DATAFILE_LOCATION/STAN/redo07.log’) SIZE  100M;

ALTER DATABASE ADD STANDBY LOGFILE GROUP  6(‘DATAFILE_LOCATION/STAN/redo08.log’) SIZE  100M;

ALTER DATABASE ADD STANDBY LOGFILE GROUP  7(‘DATAFILE_LOCATION/STAN/redo09.log’) SIZE  100M;

select * from v$standby_log;

9. start listener
10. tnsping
11. shutdown immediate
12. startup mout pfile

13. to start log applying to secondary:

alter database recover managed standby database disconnect; ---apply cuurent logfile

* To check archives are applied to secondary, issue the following command.

select sequence#,first_time,applied from v$archived_log order by first_time;

* To check if the process MRPO exists in secondary, issue the command.
SELECT PROCESS FROM V$MANAGED_STANDBY WHERE PROCESS LIKE 'MRP%';
