SQL> startup ORA-29702: error occurred in Cluster Group Service operation

Issue while startup database:

SQL> startup mount
ORA-29702: error occurred in Cluster Group Service operation
SQL> Disconnected
bash-3.2$



1> If already RAC and cluster service not running then

Solution-1 :
check if cluster services are up and running, if not please start the cluster services.


2> If it's non-RAC / after cloning /after copied binary to new(to configure standby) database.

Solution-2:
$ cd $ORACLE_HOME/rdbms/lib
$ make -f ins_rdbms.mk rac_off
$make -f ins_rdbms.mk ioracle


Above will resolved issue for sure.
