Error description

    ---------------------------------------
    NEW FUNCTION:
    Add option to dynamically append the client's hostname to

    or CMINIT) for outbound conversations, and then on the server
    update the local LU parameter sys_name with this hostname.

Problem summary

  • USERS AFFECTED: All using the Remote API Client.
    
    PROBLEM DESCRIPTION:
      NEW FUNCTION:
      Add option to automatically append the client's hostname to
      the Local TP Name when an application starts (issues
    TP_STARTED
      or CMINIT) for outbound conversations, and then on the server
      update the local LU parameter sys_name with this hostname.
    
    PROBLEM SUMMARY:
      New function described above has been added.
    

Problem conclusion

  • This new function has been added to the server and client code
    and can only be used if both the server and client have been
    updated with this new code.
    
    To use the enhancement:
     - First, query the existing setting for ptf_flags:
       snaadmin  query_node | grep ptf_flag
       + if the response shows a setting, for example:
           ptf_flags = SUPPRESS_PU_NAME_ON_REQACTPU
         then use a "+" to add the CLI_OVERWRITE_SYS_NAME flag
    
       Second, issue either of the following as needed:
         snaadmin -c define_node,ptf_flags=CLI_OVERWRITE_SYS_NAME
       or as for the example above
         snaadmin -c define_node,ptf_flags=SUPPRESS_PU_NAME_ON_REQAC
    TPU+CLI_OVERWRITE_SYS_NAME
    
      Optionally, edit the configuration file, sna_node.cfg:
      + Stop the server using the command "sna stop".
      + Edit the sna_node.cfg configuration file to update the
        ptf_flags parameter of the [define_node] record. This file
        is found in /etc/sna on AIX and /etc/opt/ibm/sna on Linux.
      + Restart server using the command "sna start".
    
     - On the client create an empty file in the install directory
       (default C:\ibmcs\w64cli) called tpnamehost (the content of
       the file does not matter so it can be small or even empty;
       for example:
       echo > c:\ibmcs\w64cli\tpnamehost
    
    Then all the TP_STARTED messages from the client will append the
    full hostname after to the value of the tp_name parameter, using
    a separator of "%" (in EBCDIC). The sys_name parameter of the
    local LU will then be updated to this client hostname. This is
    then used for routing subsequent incoming conversations on this
    LU to the appropriate client.
    
    Note that if there is a file tpnameipv4 (see APAR LI76288)
    already present on the client install directory then this new
    fix has no effect. The IP address is added in preference to the
    system name, and the sys_name is not altered.
    

Temporary fix

  • sna_v5router, libpe.o, libpe64_5.o
