IMS Connect is a TCP/IP server that enables TCP/IP clients to exchange messages with IMS OTMA. IMS Connect provides communication linkages between TCP/IP clients and IMS (datastores). It supports multiple TCP/IP clients accessing multiple datastore resources. The IMS Connect runs on an MVS or z/OS platform. IMS Connect performs router functions between TCP/IP clients and datastores. Input (request) messages that are received from TCP/IP clients, using TCP/IP connections, are passed to an IMS datastore through XCF sessions. IMS Connect receives response messages from the datastore and then passes them back to the originating TCP/IP clients.
IMS Connect supports TCP/IP clients communicating with socket calls, but it can support any TCP/IP client that communicates with a different input data stream format. Supplied or User-written message exits can execute in the IMS Connect address space to convert customer message format to OTMA message format before IMS Connect sends the message to IMS. The user-written message exits also convert the OTMA message format to customer message format before sending a message back to IMS Connect. IMS Connect then sends output to the client.
In addition to TCP/IP client communications, IMS Connect also supports local communications through the "Local" option.
