IMS Connect support for callout requests

IMS™ Connect is a required component when IMS application programs issue callout requests through OTMA to data or service providers that are external to the IMS installation. For both types of callout request, IMS Connect serves as the TCP/IP gateway between the IMS Connect client that use TCP/IP and the OTMA component of IMS.

IMS Connect supports callout requests without requiring any changes to the IMS Connect configuration statements. You do, however, have to configure the IMS Connect clients to support callout requests.

You can use the following types of IMS Connect clients to support synchronous and asynchronous callout requests:

  • IMS TM Resource Adapter
  • IMS Enterprise Suite SOAP Gateway
  • User-written IMS Connect client

The following IMS Connect exit routines support callout requests:

  • HWSJAVA0
  • HWSSOAP1
  • HWSSMPL0
  • HWSSMPL1

IMS provides various sample application programs to test callout support. For more information, see Samples for the callout function.
