Oracle Dataguard in Apps 11i E-Business Suite as Disaster Recovery
Today lets conclude dataguard/standby configuration & look at Metalink note on Dataguard configuration in Apps 11i with database 9i & 10g.After creating standby control file and moving datafiles, redo log, control file,tnsnames.ora to standby site , start standby database as mentioned below using standby control file.
SQL> startup mount
In order to put standby database in managed recovery you can use
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION; (On standby site)
To Cancel recovery you can use
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;
All these sql’s are available in Standby Configuration guide so your can refer guide mentioned in my first post on standby database.
Failover/Switchover
Failover is used if you loose your primary database or wish to break relationship between primary & standby database & convert standby database in to primary database.
Switchover is used to change role of primary to standby & vice versa.
For configuring Dataguard as Disaster Recovery solution in Oracle Applications 11i use Metalink Note # 216212.1 Business Continuity for Oracle Applications Release 11i, Database Releases 9i and 10g
Next level of Business Continuity is Application Server Guard (Currently for Standalone Application Server only) which includes middle tier recovery including database. AS Guard (Application Server Guard) also called as DSA is used for seamless Integration of Disaster Recovery solution for both Middle Tier & Database Tier. I am going to cover how to configure AS Guard in future.
