Sys Parameters, XQPCTL2
 *Conan The Librarian 

    XQPCTL2 controls improved concurrency. The default value of
    XQPCTL2 is 1, which turns on improved concurrency. Setting
    XQPCTL2 to 0 turns off improved concurrency. This parameter
    affects local access to the extent and file ID caches.

    This special parameter is used by HP and is subject to change. Do
    not change this parameter unless HP recommends that you do so.
