ORA-00439: feature not enabled: Real Application Clusters – ORA-01078: failure in processing system parameters

Cause:

I try to nomount the standby single instance database using primary RAC database pfile, i get the error due to RAC enabled cluster parameters.

kish@STDBY>startup nomount pfile='/apps01/product/12.1.0/dbhome_1/dbs/initdbx01.ora';
ORA-00439: feature not enabled: Real Application Clusters
ORA-01078: failure in processing system parameters

Workaround:

Go to pfile

-bash-4.2$ vi /apps01/product/12.1.0/dbhome_1/dbs/initdbx01.ora

Disable cluster parameters from pfile
