Using DBCA in Silent Mode to Add Database Instances to Target Nodes

You can use DBCA in silent mode to add instances to nodes on which you have extended an Oracle Clusterware home and an Oracle Database home. Before you run the dbca command, ensure that you have set the ORACLE_HOME environment variable correctly on the existing nodes. Run DBCA, supplying values for the variables described in Table 10-1,as follows:

dbca -silent -nodeList node_name -gdbName gdb_name
[-instanceName instance_name -sysDBAUserName sysdba -sysDBAPassword password]

Variable	Description
`node_name`	The node on which you want to add (or delete) the instance.

`password`	Password for the `SYSDBA` user.
