BrokerID

String

No 

Broker identifier

Must be a unique alphanumeric string of no more than n - 13 characters, where n is the maximum table name length allowed by the database. No two running brokers may have the same broker identifier.

For brokers using a JDBC-based persistent data store, this string is appended to the names of all database tables to make them unique in the case where more than one broker instance is using the same database. If a database is not used as the persistent data store, the value of this attribute is null.

For high-availability brokers, database table names use the ClusterID attribute (see Table 3–78) instead.
