Then, type asmca to launch ASMCA. collabn1:/home/oracle[RAC1]$ oenv SIDs here are: grid +ASM1 ORACLE_SID = [RAC1] ? +ASM1 The Oracle base for ORACLE_HOME=/u01/grid/oracle/product/11.2.0/grid_1 is /u01/app/oracle collabn1:/home/oracle[+ASM1]$ asmca
ASM Databases Only: Verify that both diskgroups are mounted. If you have jumpstarted or rebooted, then the BACKUP diskgroup may be dismounted. To mount it, right click then choose Mount on All Nodes. Click EXIT to close the ASM Configuration Assistant.
- Type ". oraenv" to set up the environment. Leave the default SID and enter /u01/app/oracle/product/11.2.0/db_1 for the ORACLE_HOME. Then type dbca to launch the Database Configuration Assistant.

- One last thing: edit /etc/oratab on both nodes and replace the DB name with the Instance name. Also edit the bash_profile on node 2 and set the instance name to RAC2. [oracle@collabn1 ~]$ vi /etc/oratab RAC1:/u01/app/oracle/product/11.1.0/db_1:N [oracle@collabn1 ~]$ ssh collabn2 [oracle@collabn2 ~]$ vi /etc/oratab RAC2:/u01/app/oracle/product/11.1.0/db_1:N [oracle@collabn2 ~]$ vi /home/oracle/.bash_profile export ORACLE_SID=RAC2
