issued to the instance from the Control Center or the Configuration Assistant.
This design reduces the overhead that exists when one administrative
coordinator node is spread across multiple partitions in an instance and helps to
balance incoming connections. If you are running in a single partition, you still
have to migrate DAS to use the Control Center.
If you do not want to keep your existing configuration, you can just drop the DAS
and create a new one.
If you do not have a DAS in any database partition server, create a new one. You
can find more details about DAS creation in Chapter 2, “Installation” on page 25.
