Oracle RAC 18c new features

New features in Oracle RAC/Clusterware 18c



In stand-alone databases and Oracle RAC databases, sequence can be made scalable by specifying the SCALE clause in the CREATE SEQUENCE or ALTER SEQUENCE statement.

Shared Scan Listeners - From Oracle 18c, we can have Shared Scan Listeners between clusters instead of having different scan listener for each cluster. This will save a lot of IP's and configuration aspect.

srvctl add scan_listener -clientcluster cluster_name
srvctl export scan_listener -clientcluster cluster_name -clientdata satyascan
srvctl export ons -clientcluster cluster_name -clientdata satyascandata

In DBCA silent mode, a copy of an Oracle RAC database can be created using the -createDuplicateDB command option -databaseConfigType with the value of RAC or RACONENODE.
