RMS_CONPOLICY specifies the policy to be used for dealing with
    high-contention write-shared files. This dynamic parameter can
    be used to ensure fairness between lock conversions and new lock
    requests.

    Possible values are the following:

    Value          Explanation

    NEVER          (Default) Never use the higher overhead option
                   to improve fairness for any write-shared files
                   accessed on the system; minimal overhead.
    SOMETIMES      Use this option for fairer bucket access (but
                   higher overhead) to any write-shared files with
                   global buffers enabled that are accessed on the
                   system.
    ALWAYS         Use this option for fairer bucket access (but
                   higher overhead) to all write-shared files
                   accessed on the system.

    You can set this system parameter with the DCL command SET RMS_
    DEFAULT/SYSTEM/CONTENTION_POLICY=value and display the parameter
    with the DCL command SHOW RMS_DEFAULT.

    RMS_CONPOLICY is a DYNAMIC parameter.
