Using DBCA Commands for Noninteractive (Silent) Configuration for Oracle RAC
Review this topic for the command syntax to create an Oracle RAC database using DBCA.
You can use the following command syntax to create an Oracle RAC database using the general purpose template, placing the data files in an existing Oracle ASM disk group. Nodes node1 and node2 are the cluster nodes on which Oracle RAC database instances are created. The disk group name is +ASMgrp1, and password is a placeholder for a password. The passwords can be all the same password or different passwords each time:
# su oracle -c "$ORACLE_HOME/bin/dbca -silent -createDatabase -templateName
General_Purpose.dbc -gdbName $DBNAME -sid $ORACLE_SID -sysPassword password
-systemPassword password -sysmanPassword password -dbsnmpPassword password
-emConfiguration LOCAL -storageType ASM -diskGroupName ASMgrp1
-datafileJarLocation $ORACLE_HOME/assistants/dbca/templates -nodeinfo
node1,node2 -characterset WE8ISO8859P1 -obfuscatedPasswords false -sampleSchema
false -asmSysPassword password"
