is equal to "1". is equal to "2", e.g. ORCL1, ORCL2.

5) change the location of control file in parameter file

local drive to shared cluster file system location

ie control_files='/control01.ctl'

to ie control_files='/control01.ctl'

6) create spfile from pfile( spfile should be stored in shared device)

export ORACLE_SID=ORCL1
sqlplus "/ as sysdba"
create spfile='/spfileORCL.ora' from pfile='/tmp/initORCL.ora';
exit

7) Create the $ORACLE_HOME/dbs/init.ora e.g. initORCL1.ora file that contains the following entry

spfile='spfile_path_name'

spfile_path_name is the complete path name of the SPFILE.

example :-

spfile='/cfs/spfile/spfileORCL1.ora'

8) create new password file for ORCL1 instance.

orapwd file=orapwORCL1 password=oracle

9) start the database in mount stage

10) Rename the datafile,redo logs to new shared device

alter database rename file '' to '
11) Add second instance redo logs (or more when multiple instances will be started)

alter database
add logfile thread 2
group 3 ('group 4 ('
alter database enable public thread 2;


12) create the second (or more) instance undo tablespace from existing instance

Path and file name will different for your environment


CREATE UNDO TABLESPACE UNDOTBS2 DATAFILE
'/dev/RAC/undotbs_02_210.dbf' SIZE 200M ;


13) Open your database (i.e. alter database open;) and run $ORACLE_HOME/rdbms/admin/catclust.sql to create cluster database specific views within the existing instance


2. On the second node and other nodes

14) Set ORACLE_SID and ORACLE_HOME environment variables on the second node

15) Create the $ORACLE_HOME/dbs/init.ora e.g. initORCL2.ora file for the second node the same way as with point 7.

16) create new password file for second instance ORCL2 instance as in point 8

orapwd file=orapwORCL2 password=oracle

17) Start the second Instance

3. on one of the nodes

18) After configuring the listener,you have to add the database in cluster as below

19) in case ASM is used, add the rdbms instance / asm dependency, e.g.
