Error description

  • When SA/390 ( SA390 ) workstation is used in TWS z/OS
    and System Automation commands are used that have variable
    substitution, it is possible that some control blocks ( TUB and
    JDAT ) are not freed.  Subpool2 key8 shows very high usage
    above the line.  The following message may be seen in the
    controller EQQMLOG:
    EQQN032E UNABLE TO OPEN VSAM FILE EQQCP1DS, VSAM RC = 0008,
    REASON = 0136
    where REASON136 indicates an out of storage situation.
