Service Program re-bind to open files in DFTACTGRP

If a Service Program procedure opens a file in the Default Activation Group and it's later closed with RCLRSC from a calling program, the service program isn't made aware of this and it still has a reference to the "now unknown" space. When it tries to use the file on a subsequent attempt, an error is thrown: "Tried to refer to all or part of an object that no longer exists". I understand this was never intended for the DAG, but it's not always an easy transition to use named activation groups everywhere a service program procedure is desired to be used.

The goal is to have the service program detect the space in the DAG is no longer there/usable and re-bind to the file being accessed.

Use Case:

Use a service program procedure in a stream where there may be a mix of OPM/ILE and it's not a viable/safe option to change to a named activation group.

    IBM has no plans to changed the design and implementation of this. This could cause significant issues for existing programs, and the risk and the amount of effort to change this is not worth any implied benefit.

    From my point of view this is more a bug than a "feature". We opened a PMR way back when the major release numbers was a "3", maybe v3r1. Sadly IBM did not want to fix that. I wonder if this RFE has a chance to get it fixed. I support this RFE, because it would make it possible to use service programs in a mixed environment of OPM and ILE programs safely.

    We made a very hard and exhausting transition of our application from OPM to ILE. So I know how hard it is to get that done for large applications.

    It would be very interesting to know why IBM does not want to fix the RCLRSC issue.
