hi,

first check form which sequence no the database has not appiled the archive logs

SQL> select sequence#, applied, archived from v$archived_log order by sequence#;

·It must be always kept in mind for a switchover, the production database (PR) must be made standby first.

# To check the switchover status for the PR database.
SQL> select switchover_status from v$database;
SWITCHOVER_STATUS
--------------------
SESSIONS ACTIVE


# For changing the Production Database (PR) into Standby Database (DR).
SQL> alter database commit to switchover to physical standby with
session shutdown;
Database altered.


# Always shutdown the database to apply these changes.
SQL> shutdown immediate;

# Startup database in nomount stage
SQL> startup nomount;

# Standby database must always in a mount stage (Note: - Don’t start the database in open stage.
SQL> alter database mount standby database;
Database altered.


# To start database in MRM (Manage recovery mode) for auto applying of Archive logs.
SQL> alter database recover managed standby database disconnect from session;
Database altered.


·The above SQL queries the production database is transferred into a standby database.
·Now it's safe to transform standby database into production database.

***************
Apply the following SQL the DR side.

# To check the switchover status for the DR database.
SQL> select switchover_status from v$database;
SWITCHOVER_STATUS
--------------------
TO PRIMARY


#For checking whether the archive logs are being archived and applied on the DR database.
SQL> select sequence#, applied, archived from v$archived_log order by sequence#;
SEQUENCE# APP ARC
---------- --- ---
3470 YES YES
3471 YES YES
3472 YES YES
3473 YES YES
4 rows selected.


# For switching the DR to PR.
SQL> alter database commit to switchover to primary;
Database altered.




# Always shutdown the database to apply these changes.
SQL> shutdown immediate;


# Starting up the database in open mode.
SQL> startup;


SQL> select switchover_status from v$database;
SWITCHOVER_STATUS
--------------------
SESSIONS ACTIVE


·At this stage the DR is in Production and PR is acting as standby.

Amit

Dear Zuhair,

i think there is no archive (ARC00019_0618916032.001) present in the location c:\archive\

manually copy , paste the archive log (ARC00019_0618916032.001) from the PR to DR and recover it.

Regards,
Amit
