CPSM API: A new query function to identify available CMAS's

The CPSM API should support a new query function that could be called prior to any CONNECT operation. This query would scan and locate all active ESSS's on the local LPAR via the z/OS subsystem chain, extracting from each ESSS information about all active CMAS's and returning this information to the caller. The information returned would include the CMAS name, the CICS/TS version/release, and any other identifying information that might be easily obtained from the ESSS that the API routine could use in choosing a CMAS for a subsequent CONNECT operation.

    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

    Securing access to this new query interface via SAF would be fine. Might that alleviate some of the security concerns? The overall objective of the request is to afford CPSM API users the ability to learn about the environment they're running in while requiring little or no "advance knowledge" of it.

    This requirement has been re-evaluated. Looking at current plans, it is not likely that this would be implemented in the next two CICS TS releases, so correspondingly this requirement is being rejected. You have an opportunity to resubmit in eighteen months time if you wish it to be considered then. There are a number of technical and security problems here that would need to be resolved before we could complete a solution for this and still wouldn't provide the complete capability.

    Have you tried doing the CONNECT, without specifying a CONTEXT or SCOPE? You should be able to request CMAS related views without specifying the request CONTEXT and SCOPE at all. This has the added benefit that you are not bypassing security.

    The Infocenter states the following about the CONNECT command:
    "If you do not specify the CONTEXT option, the default context for the thread is the CMAS to which the thread is connected."

    Have a look at the following resource tables:
    CPLXCMAS - CMAS in CICSplex definitions
    CMASPLEX - CICSplexes managed by CMAS
    CMASLIST - CMASs known to local CMAS
    CMAS - CMAS detail (this one contains the CPSMVER field which has the CICS TS release).

    You should be able to get the CMASLIST records back without specifying a context. This will give you a list of all defined CMAS. From there do EXEC CPSM GET OBJECT(CMAS) CONTEXT() for each CMASLIST record in the previous request. This should give you everything you need.
