You can configure multiple brokers by adding more [UBroker.OR.broker-name] and [Environment.broker-name] sections. Each broker instance must have a unique name. The brokers can share the properties that you define in the parent entity [UBroker.OR] section.
If you want to access multiple Oracle databases, you must configure one broker per database, and each broker must run in a separate directory and a distinct environment. For example, each broker must have a unique setting for ORACLE_SID.
