• Install the database software only on primary and standby node
• Configure the network on the both node
• On primary node create the database
• 

• Configure the listener and database services in the primary node named it your primary database name

• Restart the listener using the command lsnrctl stop,lsnrctl start

• Do the following steps in the primary node
• set the following parameter in the primary node
• Check the database in archive log mode if not in that mode enable the archive log

• backup the database using the rman command

• copy the database password file from  primary to standby database node
• Rename the copied database password file in standby node
• Create the parameter file using the below command in standby node

• rename the password file

• Start the standby database with nomount mode in standby node

• Add the listener and database services in standby node named it your standby database name

• Restart the listener (stop and start) on the standby node

• Add the primary standby database name in the service name on primary node and standby node
• This example shows only adding on primary and  do the same steps on the standby node

• Restart the listener  on primary node and standby node also

• Create the directories for the standby database on standby node
• Backup the database using the rman command

• After completion of the backup create the script like given bellow

• On the primary node connect target and auxiliary database and it connected                   successfully run the script

• In primary node give the bellow command to generate the log

• Check the database status on the standby node

• In standby node check if the logs are applied here logs are not applied

• Give the bellow command to apply the log on the standby database
• Once the command is executed log are automatically shipped to standby node

• This steps are used to configure the dataguard
• Set dg_broker_start value true on both node follow the steps

• Add the database services on the both nodes
• Named it given bellow
• Restart the listener on both node

• In standby node set the parrameter local_listener=stydata

• In the primary node create the dataguard configuration
• Enable the dataguard configuration
• Do the switchover process

• Check the standby node database status after the switch over process

           The standby node database will be opened and primary node database

           Will be in mounted
