Database with ASM in the Continentalclusters in the primary cluster

The procedure to start the disaster recovery Oracle RAC database with ASM is identical to the procedure for starting a complex workload in a Continentalclusters. Run the cmrunpkg command with the site controller package name managing the Oracle RAC/ASM workload in the primary cluster as the argument.
