With this enhancement, you can now concurrently create or terminate Oracle databases even if the VM cluster is in the Updating state.

The number of databases that can be created on a cluster depends on the available memory on the VMs. For each database, by default, 12.6 GB (7.6 GB for SGA and 5 GB for PGA) is allocated if the VM has greater than 60 GB of memory. If the VM has less than or equal to 60 GB, then 6.3 GB (3.8 GB for SGA and 2.5 GB for PGA) is allocated. Also, Grid Infrastructure and ASM consume some memory, approximately 2 to 4 GB.

A database that is being created cannot be terminated. You can, however, terminate other databases in the VM Cluster.
