Error description

  • The queue manager storage configuration topic states "The
    MEMLIMIT parameter of the queue manager JCL defines the maximum
    amount of 64-bit storage available. 3GB of storage,
    MEMLIMIT=3G, is the minimum you should use". The shipped sample
    procedures should be revised to match the documented
    recommended minimum.
