Integration Server includes predefined JNDI provider aliases. Integration Server creates the aliases the first time Integration Server starts. If the aliases existed in an Integration Server that was migrated from a previous version, Integration Server keeps the existing aliases. That is, Integration Server does not overwrite the previous alias definition.

The predefined JNDI provider alias for Integration Server is DEFAULT_IS_JNDI_ PROVIDER, a JNDI provider alias with predefined settings for establishing a connection to the local instance of IBM webMethods Universal Messaging. If IBM webMethods Universal Messaging is not installed in the same directory as Integration Server, then the DEFAULT_IS_JNDI_PROVIDER uses a provider URL of nsp://localhost:9000.
