       /SYNCHRONIZE
       /NOSYNCHRONIZE (D)

    Indicates that the query result must be synchronized with the
    current state of the virtual library being queried. By default,
    /NOSYNCHRONIZE causes SCA to do as little processing as necessary
    to evaluate the query. This can lead to query results that reflect
    the state of the virtual library at the time of a previous query.

    The /SYNCHRONIZE qualifier specifies that the query result must
    be synchronized with the current virtual library. SCA attempts
    to minimize the amount of processing, but the result is still
    synchronized with the virtual library that was in effect at the
    time the query was evaluated.
