Subject: BI-DIRECTIONAL TCP/IP

Category: 
  - Routine
  - Data Dictionary

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

  This patch introduces TCP/IP as a transport layer for the HL7 package. 
  For information on how to work with TCP/IP HL7 interfaces, see the new 
  "DHCP HL7 User Manual: TCP/IP Supplement", which is in the file
  HL71_6P19.PDF, available from the Customer Service anonymous directories.
  
  This patch will convert the messages in HL7 MESSAGE ADMINISTRATION, file
  773, and in HL7 MESSAGE TEXT, file 772. To speed up the conversion, run
  the 'Purge Message Text File Entries' option to remove old messages.
    
  Earlier version of Patch 19, prior to test version 25, are Uni-directional.
  All TCP Logical Links must be redefined to work with this version of patch
  19.  Messages might also need to be modified.

  Installation Instructions:
  ==========================    
    1.  Use the option 'Purge Message Text File Entries' option to remove
        old messages. Suggested answers:
  
     Enter the cutoff date for all messages REGARDLESS OF STATUS: T-90//T-28
     Enter last INCLUSIVE date for status SUCCESSFULLY TRANSMITTED: T-7//T-2
     Purge entries with an ERROR STATUS? NO//YES
     Cutoff date for AWAITING ACKNOWLEDGEMENT status: T-30//T-7
  
    2.  Make sure all messages have been transmitted.  Run the option 'Systems
        Link Monitor', under the 'Communications Server' menu, and make sure
        'messages to send' is equal to 'messages sent' for all Logical Links.
  
    3.  Shutdown all Logical Links and incoming and outgoing filers. Use the
        'Shut Down All Logical Links', 'Stop all incoming filers', and 'Stop
        all outgoing filers' options.
  
    4.  User are NOT allowed on the system during installation.  Inhibit
        logins and place Taskman in a wait state, use the option 'Place
        Taskman in a WAIT State'.  Have the submanager shutdown after
        finishing their current task.
  
    5.  Some of these routines are new.  Currently we do not recommend that
        you add these routines to your map set.
    
    6.  Use the INSTALL/CHECK MESSAGE option on the PackMan menu. This
        option loads the KIDS package into a Transport global onto your
        system.
  
    7.  You now need to use KIDS to install the Transport global. From
        programmer prompt Do ^XPDKRN.
    
    8.  On the KIDS menu, under the Installation menu, use the following
        options:
    
           2 Verify Checksums in Transport Global
           3 Print Transport Global
           4 Compare Transport Global to Current System
           5 Backup a Transport Global
           6 Install Package(s)
               INSTALL NAME: HL*1.6*19
                             =========
  
        The length of the install depends on the size of file 772.  The
        average install takes about 15 minutes for 40,000 entries in file
        772.
  
    9.  Allow users back on the system and remove Taskman from wait state,
        use the option 'Remove Taskman from WAIT State'.
  
   10.  Use the 'Edit Communication Server parameters' option to add a Mail
        Group to the 'Mail Group for Alerts' field.
  
   11.  Startup all Logical Links and incoming and outgoing filers. Use the
        'Restart All Links and Filers' option.

  Data Dictionary Modifications:
  ============================== 
  
   869.1  HL LOWER LEVEL PROTOCOL TYPE
          No modifications were made to the data dictionary.  One record,
          TCP, has been added and will be merged into your current data.
   
   869.2  HL LOWER LEVEL PROTOCOL PARAMETER
   
          400.01    TCP/IP ADDRESS (F)  [400;1]
          400.02    TCP/IP PORT (NJ5,0)  [400;2]
          400.03    TCP/IP SERVICE TYPE (S)  [400;3]
          400.04    PERSISTENT (S)  [400;4]
          400.06    STARTUP NODE (P14.7)  [400;6]
  
   771.6  HL7 MESSAGE STATUS
          No modifications were made to the data dictionary.  Several new
          statuses have been added and will overwrite your current data.
  
   771.7  HL7 ERROR MESSAGE
          No modifications were made to the data dictionary.  Several new
          errors messages have been added and will overwrite your current data.
  
   772  HL7 MESSAGE TEXT
          The .01 field, DATE/TIME ENTERED, has been changed from a pointer to
          a date/time field.
  
   773  HL7 MESSAGE ADMINISTRATION
          The .01 field, DATE/TIME ENTERED, has been changed from a date/time
          to a pointer to file 772.  Fields have been added to this file for
          bi-directional TCP messages.
  
  
  New Option
  ============================== 
  
  'View Transmission Log'     Option name: HL VIEW TRANSMISSION LOG
       This option is used to view the Transmission Log; i.e.,
       the Message Administration File entries.  It displays those
       messages that have been sent or are pending. Display of
       messages with HL7 errors or exceptions is not yet supported.
  
  New Alert
  ==============================
  If a message exceeds the 'RE-TRANSMISION ATTEMPTS' for a Logical Link, an
  alert will be generated.  The alert will be sent to the Mail Group defined
  in the HL COMMUNICATION SERVER PARAMETERS file, 869.3.
