Subject: FIX STUCK LINKS

Category: 
  - Routine

Description:
============

 Test sites:  MPI, San Francisco, Montana, Reno
  
 NOIS Resolved: HWH-0204-42260
 
 This patch fixes these problems:
 
 1) An outgoing logical link might get stuck on a particular message if, due 
    to a quirk of timing, the application acknowledgment is returned before
    the commit acknowledgement.
 
 2) This patch replaces a variable being used in PING^HLMA to its original 
    value (!) to flush the network device.  The variable was inadvertently 
    placed to use a future functionality provided by Kernel patch XU*8.0*275 
    and a future patch HL*1.6*113.  
 
 3) The in-filer currently pauses for around 22 seconds before processing 
    the next in-queue. This long pause was introduced in patch HL*1.6*109 
    because it was discovered to be necessary for VMS DSM sites that use disk
    buffering. However, because this long pause slows down the
    responsiveness of HL7 messaging, and since the official recommendation
    of the AXP team is that DSM/VMS sites should NOT be using disk 
    buffering, this patch reduces that pause to 2 seconds.
 
    Note:  For VMS DSM sites, if you are not sure whether or not you are
    utilizing disk buffering, please refer to the patch instructions for 
    HL*1.6*109 for instructions.

  Installation Instructions:
  =========================
    1.  Users are allowed to be on the system during the installation.
  
    2.  VMS SITES: Review your mapped routine set.  If any of the
        routines listed in the ROUTINE SUMMARY section are mapped, they
        should be removed from the mapped set at this time.
  
    3.  Shutdown all Logical Links, incoming and outgoing filers, and
        the Link Manager using the Filer and Link Management options
        listed below:
  
          Stop All Messaging Background Processes [HL STOP ALL]
          TCP Link Manager Start/Stop [HL START/STOP LINK MANAGER]
  
        VMS SITES ONLY: Disable all HL7 TCP/IP services for this
        installation.
  
    4.  Use the 'INSTALL/CHECK MESSAGE' option on the PackMan menu. This
        option will load the KIDS package onto your system.
  
    5.  This patch is now loaded into a transport global on your
        system. The next step is to use KIDS to install the Transport
        global. To do this, use the 'Installation [XPD INSTALLATION 
        MENU]' menu.  You should use each of the following 'Installation'
        menu options in the order shown below:
  
          Verify Checksums in Transport Global
          Print Transport Global
          Compare Transport Global to Current System
          Backup a Transport Global
          Install Package(s)
  
        When using the 'Install Package(s)' menu option to install 
        the patch build, you will be asked several questions.  The 
        questions asked, and the answers you should supply, are 
        shown below.
  
          INSTALL NAME: <HL*1.6*115>
          Want KIDS to INHIBIT LOGONS during the install?  <NO>
          Want to DISABLE Scheduled Options, Menu Options, and
          Protocols?  <NO>
  
 
    6.  Start up all Logical Links and incoming and outgoing filers using
        the Filer and Link Management Option's 'Restart/Start All Links
        and Filers [HL TASK RESTART]' menu option.
  
        (Note that links that do not have "autostart" enabled will need
        to be restarted manually.)
  
        VMS Sites:  If you previously disabled an HL7 TCP/IP service for 
        this installation, you may enable it now.
  
    7.  VMS Sites:  After the patch has been installed, rebuild your
        map set, if necessary.
  
    8.  Start Link Manager using the 'TCP Link Manager Start/Stop [HL
        START/STOP LINK MANAGER]' menu option.
