provide Display SHCDS command with results that go to SYSLOG for automation.

SHCDS commands  work both in batch and in the TSO/E foreground, but the output isn't available in SYSLOG.
Automation around SMSVSAM/RLS issues would be easier if we could drive standard z/os commands such as /D SHCDS xxx and have output go to SYSLOG.

    As we understand it, this RFE is a request to ?mask? the output of the SHCDS LISTSUBSYS(ALL) command, or something equivalent, to only display subsystems with lost or retained locks.

    It is a potential roadmap item but we don't have a release/date to provide at this time

    Based on documentation:

    RLS and TVS Recovery Guidelines Terri Menendez 02/28/2024

    Part 5. Transactional Recovery

    1. A. Retained Locks

    Retained locks occur when active locks are held by recoverable subsystems (i.e. CICS or a TVS instance) for recoverable data sets (i.e. LOG(UNDO/ALL)) and one of the following occurs:

    1. Recoverable data set is closed without ending all active transactions (i.e. cancel CICS).

    2. SMSVSAM terminates with active locks.

    3. System failure with active locks.

    4. Backout fails (shunted) for one or more transactions holding active locks.

    When a data set has retained locks, record management requests for the same record locks by RLS sharers will fail with RC=8 RPLERRCD=24(x’18’).

    To determine which subsystem have retained locks issue:

    SHCDS LISTSUBSYS(ALL)

    SHCDS LISTSUBSYSDS(subsys)

    SHCDS LISTDS(baseclustername)

    Based on this RFE description:
    SHCDS commands  work both in batch and in the TSO/E foreground, but the output isn't available in SYSLOG.
    Automation around SMSVSAM/RLS issues would be easier if we could drive standard z/os commands such as /D SHCDS xxx and have output go to SYSLOG.

    my immediate comment is that you could add automation in your applications for the SHCDS message (IGW6xxx) from the SHCDS commands.  However, like you said, "Running a batch job isn't very efficient when trying to automate based on messages." The main problem with SHCDS commands going to operlog is that they are generally voluminous and not suited for the console.  Could you tell us what specific SHCDS command outputs you are looking for, so maybe we can come up with a more specific solution.
