Platform application operation registry

In this RFE I want to put two things, because they belong somehow together. If this should be separated, let me know and I will raise a second one.

---------------------------------------------------------------------------------

System constellation

We have two Cics Regions, one for Java and one for PLI Programs. The reason is, because the Java Regions should run on a ZNULC LPAR, to get a cheaper price.

---------------------------------------------------------------------------------

First issue:

A Java Servlet (Java Region) now wants to invoke an PLI Application (PLI Region). At the moment you need dynamic routing to make this possible. @Cics Team: Please correct me if this is wrong. The second possibility to solve this would be to define an operation on an remote entry point, what is not possible at the moment.

---------------------------------------------------------------------------------

Second issue:

We have hundreds of PLI Modules which are invoked with an operation. We call them Method Modul. They all are build in the same way. There is a commarea with one pointer. This pointer points to a Method (z.B.: PRODUCT_DATA_GET), a data in, data out and a return code. For me the operation from the application is a little bit the same on a public scope.

I have discussed this with the developers and it would be great to have the possibility to define multible entry points on the same module. On the other side in the program the developer wants to extract the operation and handle the workflow in different ways.

---------------------------------------------------------------------------------

In my opinion the operation should be not connected to the program this is not realy flexible and you allways have to define some sort of routing in the region. It would be better to have a sort of operation registry table in the platform where every application which is installed is registered.

This things would be solved:

-> In this way you wouldn't need any routing for an invoke application, because from the binding you know where the program is running.
-> It would be possible then to add multiple entry points to on program.
-> Easily provide unique operations each platform an check this.

I hope I have described everything enough.

Let me know if not.

Regards

Peter

    We have assessed this requirement. We have no current plans for this to be implemented and so this requirement is being declined at this point. The requirement will be kept in the RFE system and might be reassessed in the future. You also have an opportunity to resubmit in twelve months time if you wish it to be reconsidered then.

    Due to processing by IBM, this request was reassigned to have the following updated attributes:
    Brand - Servers and Systems Software
    Product family - Transaction Processing
    Product - CICS Transaction Server

    For recording keeping, the previous attributes were:
    Brand - WebSphere
    Product family - Transaction Processing
    Product - CICS Transaction Server

    Comment 8: 2. Let me see if I understand correctly. You have many programs today each invoked with a commarea. One parameter in the commarea is an method/operation value set by the caller. Instead you would like to invoke this program as an entry point but use different operations with the backend program inquiring the application context rather than the commarea to determine the operation.

    It seems to me there is not less code to write here, possibly more.

    1) If you have only a single application not calling any other this is fine, but if you have multiple applications working as microservices you have to be able to call every Operation on the platform from every place. The Trigger here for me is the platform because this things belong together. everything else doesn't matter. In fact it should be possible to just throw an applicaiton on a platform an every other application no matter on which cics it Region runs should be able to call it.

    There is another RFE from me open which goes in the same direction. It is about automatic MRO Connections for regions defined in a platform.

    2.) Of course I could make a program for every entry Point, but in fact no one will pay the Change of code in the Software. If the entry Points should get used I Need a Maximum flexibility to just add it to the existing world. This is what the programmers will do something else they hardly will.

    1. Is it possible to make the front end Java servlet and backend PLI modules part of the same application then simple use DPL? This can be static or dynamic routing
    2. Can you not declare each module an entry point
