rac off
1. login as the oracle software owner and shutdown all database instances on all nodes in the cluster.
2. cd $oracle_home/rdbms/lib
3. make -f ins_rdbms.mk rac_off
if this step did not fail with fatal errors, proceed to step 4.
4. make -f ins_rdbms.mk ioracle
note: if these steps fail with a fatal error, then you will need to open a service request and submit these errors to oracle support for analysis.
