ORA-29702: error occurred in Cluster Group Service operation
If you are working on Solaris and having Oracle database 10g or above, you might face ORA-29702 issue after reboot of your server or starting up the database.
Your database is not running on RAC but still oracle assuming it to be RAC instance.
Very simple solution to overcome this situation is to re-link oracle libraries.
Step 1. Shutdown the database completely if no-mount or any other state.
Step 2. Relink with RAC OFF :
Run following two commands one by one.(Refer below screen shots for the same.)
$ make -f ins_rdbms.mk rac_off
$ make -f ins_rdbms.mk ioracle
Step 3. Startup the database
Now start your database normally.
That's it.. Database will be started normally without any error.
