The generateEnvironmentIdentity command enables you to generate a new environment identity for an environment. The environment identity uniquely identifies an environment and it is shared by all databases in an SDS environment.
The syntax of the generateEnvironmentIdentity command in the jdbutilb command line is as follows.
jdbutilb path=database-path
ini=initialization-file-name
generateEnvironmentIdentity
When you change the environment identity of the primary, the change is written to the journal and is replayed automatically on SDS secondary databases. It comes into effect when the database is restarted.
