Step-1: Check the SCN of Standby ( Data guard ) database and Find the lowest SCN from the following Queries.
SQL> SELECT CURRENT_SCN FROM V$DATABASE; CURRENT_SCN -------------- 1165261 SQL> select min(fhscn) from x$kcvfh; MIN(FHSCN) ---------------- 1162291 SQL> select min(kc.fhscn) from x$kcvfh f, v$datafile d where kc.hxfil =dd.file# and dd.enabled != 'READ ONLY'; MIN(kc.FHSCN) ---------------- 1161196
Step-2: Stop the Dataguard MRP ( Apply ) Process and shutdown Standby database.
SQL> alter database recover managed standby database cancel; SQL> shutdown immediate;
Step-3: Take an Incremental Backup from Production database using the lowest SCN as follows.
RMAN > backup incremental from scn 1161196 database format '/oracle/increment.rman' DEVICE TYPE DISK;
Step-4: Transfer the Incremental backup to the Standby database from Production server.
[oracle@msddbadm01 ~]$ scp incremental.rman 192.168.9.125:/oracle/backup/backup_Incre
Step-5: Create a new Standby Controlfile on Production database and transfer it to Standby database.
SQL> alter database create standby controlfile as '/oracle/stand01.ctl'; [oracle@msddbadm01 ~]$ scp standby.ctl 192.168.9.125:/oracle/backup/
Step-6: Startup Standby database in nomount mode.
SQL> startup nomount
Step-7: Restore new standby controlfile on Standby database.
RMAN> restore standby controlfile from '/oracle/backup/standb01.ctl';
Step-8: mount the standby database.
SQL> alter database mount standby database;
Database altered.
Step-9: Catalog the new Incremental backups on Standby Server as follows.
RMAN> catalog start with '/oracle/backup/'; List of Cataloged Files ======================= File Name: /oracle/backup/increment.rman
Step-10: start Recover database on Standby database.
RMAN> recover database;
Step-11: Now you can start the MRP Process to apply new logs.
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE DISCONNECT FROM SESSION;
