Problem summary

  • APAR NUMBER:  PJ40981
    PRODUCT:  z/TPF
    FUNCTIONAL AREA:  CRAS SUPPORT
    SHIPPED IN PUT:  10
    
    ABSTRACT:
    The ZACRS command should not allow the 1052 alternate PRC to be
    defined to the same SDA that the 1052 PRC is currently using.
    This APAR corrects APAR PJ31181.

    COMMENTS:
    The ZACRS command should not allow the alternate PRC to be
    defined to the same SDA that the PRC is currently using. The
    "ZACRS FBK" command with the "SUB" parameter will allow an
    operator to change the fallback address for which the TPF
    system will attempt to use when doing 1052 PRC fallback
    processing. The problem is that there is no check in the
    current processing of this command to prevent the operator from
    defining the same subchannel address to the alternate PRC for
    which the system PRC is currently using. If the operator
    subsequently attempts to validate the new 1052 alternate PRC
    device by using the "ZACRS FBK" command with the "OPT-VAL"
    parameter, the processing of the validation will dismount the
    device after it has been validated, which has the harmful
    repercussion of disconnecting the system PRC, thus leaving the
    system without a Prime CRAS console.
    

Problem conclusion

  • SOLUTION:
    Real-time segment CVPX, which processes the "ZACRS FBK" command
    for the 1052 PRC fallback processing, has been modified to
    ensure that if the "SUB" parameter is included in the command,
    the address specified is not the same as the address that is
    currently being used as the PRC device address. If the address
    specified is the same, then the command is rejected with a new
    ACRS0041E error message.
    
    COREQS: NO
    None.
