Read-only scale-out set-up

The following steps must be performed to configure a scale-out system:

Start a database server with the -xp on database option. This database server is the root node for the scale-out system.
Add the scale-out object definitions to the root database. You must define the servers and set options for the servers.
Make backup copies of the root database.
Start the copy nodes (the backup copies of the database).

Kerberos authentication and integration login considerations

If you are using the NodeType connection parameter to redirect connections that use Kerberos authentication or integrated logins, all the database servers in the scale-out tree must be configured as follows:

Integrated logins All of the database servers in the scale-out tree must be a part of the same Windows user group or be configured to allow the same Windows users to access them.
Kerberos authentication All of the database servers in the scale-out tree must have Kerberos authentication enabled. The Kerberos server principal for all the servers in the scale-out tree must have the same realm.
