Step by Step document to Create Physical Standby Database from Active Database

using RMAN

Step by step document to create a physical standby database using RMAN DUPLICATE FROM ACTIVE DATABASE command without shutting down the primary and using primary active database files (No need to take backup)

Database Name :- WHITE Primary db_unique_name :- WHITE standby db_unique_name :- BLACK

Primary Database Server Name :- DC1 Standby Database Server Name :- DC2

Steps:-

1.Make the necessary changes to the primary database. a. Enable force logging.

b. Creating the password file if one does not exist. c. Create standby redologs.

d. Modify the parameter file suitable for Dataguard.

e. Change the database to archivelog mode if it is in no archivelog mode. 2. Ensure that the sql*net connectivity is working fine.

----if not add an entry for database in TNSNAMES.ORA and LISTENER.ORA file for primary and standby database. 3. Create the standby database over the network using the active(primary) database files.

a.create a password file for standby database

The username is required to be SYS and the password needs to be the same on the Primary and Standby. The password file name must match the instance name/SID used at the standby site, not the DB_NAME. b. Create the initialization parameter file for the standby database (auxiliary database)

c. Create the necessary mount points or the folders for the database files

d. Run the standby creation ON STANDBY by connecting to primary as target database.
