I have created Oracle 10g Primary database where control file locations are as follows:
Then I have created standby database in standby server where the control file locations are as follows:
Now if I give command 'alter system switch logfile;' no. of times in Primary server then check it in Standby by 'SELECT SEQUENCE#, FIRST_TIME, NEXT_TIME FROM V$ARCHIVED_LOG ORDER BY SEQUENCE', its showing the increasing SEQUENCE# properly.
But if I want to open the standby database by the command 'alter database open read only;' then its showing error as
SQL> alter database open read only;
alter database open read only
ERROR at line 1:
ORA-16004: backup database requires recovery
ORA-01157: cannot identify/lock data file 1 - see DBWR trace file
ORA-01110: data file 1: 'P:ORACLEPRODUCT10.1.0ORADATATCENGSYSTEM01.DBF'
Can anyone please tell me where I have made the mistake?
