TCP/IP connections to IMS Connect

TCP/IP can be used for the connections between the IMS™ TM resource adapter and IMS Connect in both distributed and z/OS® environments.

When your application is on a distributed platform, the connection between the IMS TM resource adapter and IMS Connect must be a TCP/IP connection. For example, if the IMS TM resource adapter is installed on WebSphere® Application Server on Windows, AIX®, Solaris, Linux, Linux for System z®, or HP-UX, the IMS TM resource adapter must connect with IMS Connect by using TCP/IP connections. You can also optionally use TCP/IP connections if the IMS TM resource adapter is installed on WebSphere Application Server for z/OS.

TCP/IP connections to IMS Connect are associated with an identifier called the client ID. IMS Connect ensures the uniqueness of these client IDs for all of the socket connections to it.

TCP/IP connections to IMS Connect can be one of the following two types:
  • Dedicated persistent socket connections
  • Shareable persistent socket connections
The client ID is determined differently for the two types of socket connections.
