How to send a CICS query to an application running on an AIX server?

We are running CICS TS 1.3 and we would like to send a message (query) to an application running on an AIX server via TCP/IP. How can this be accomplished?


CICS does not provide any XC facilities to issue TCP/IP requests, instead you have to use a native call interface. This is, esentially, the same technique as coding a batch TCP/IP program : Establish the connection, send a request, wait, get the reply and take down the connection.

Have a look at the previous comments in this forum for more info on this and peruse 'SC31-7131 TCP/IP V3R2 for MVS: CICS TCP/IP Socket Interface Guide' which is uptodate enough to give you an idea of how to proceed: but beware, it describes things in C - don't be put off by this, later chapters talk about how to use the functions in a 'proper' language.
