IHHUBDESCREQ, A configuration requires a way identify an InfoHub - there is no explicit identification and defaulting did not find an existing InfoHub
InfoHub Error: If the InfoHub Descriptor is not specified, configuration processing uses the current value of gtmgbldir to see if the current global directory was previously associated with an InfoHubID, and, if so, uses the InfoHubID associated with that global directory. If the current global directory path was never used in association with an InfoHub ID, the configuration fails with the IHHUBDESCREQ error.
Action: Always specify an InfoHub Descriptor in your configuration file. Otherwise, ensure that the current global directory was previously associated in an InfoHubID.
