       THE ADSTAR DISTRIBUTED STORAGE MANAGER AND TCP/IP



               THE ADSTAR DISTRIBUTED STORAGE MANAGER AND TCP/IP

 The  ADSTAR  Distributed  Storage  Manager  (ADSM) is very specific about its
 TCP/IP requirements because it uses socket programming interfaces rather than
 high-level applications such as File Transfer Program (FTP)  or  the  Network
 File System (NFS).

 o   The DOS environment requires either of two products:

     1.  IBM's TCP/IP Version 2 for DOS (02G7087); or,

     2.  FTP Software's PC/TCP Version 2.1 or later

 o   The Microsoft Windows environment requires any of three products:

     1.  IBM's TCP/IP Version 2.1 for DOS (02G7087); or,

     2.  FTP  Software's  PC/TCP Version 2.1 or later with the current version
         of the PC/TCP WINSOCK.DLL

     3.  The NetManage,Inc TCP/IP for Windows with the WINSOCK.DLL

     Unfortunately, the optimism about being  able  to  support  any  vendor's
     TCP/IP  with the WINSOCK application programming interface was unfounded.
     Since the availability of Release 1, we have discovered that many  TCP/IP
     implementations  that work under Windows do not work with ADSM.  The list
     of those that do not work is too long to include in this document.    The
     list of those that DO is shown above.

 o   The  OS/2 environment requires IBM's TCP/IP Version 1.2 or later and will
     not work with any other vendor's implementation of TCP/IP.

 o   The Apple Macintosh requires Apple Computer's MacTCP Version  1.0.1  with
     an Ethernet adapter card.

 o   The MVS and VM Servers require IBM's TCP/IP Version 2, Release 2.  (Prod-
     uct  number  5735-HAL  for  MVS and 5735-FAL for VM.) The server uses the
     Inter-User Communications Vehicle (IUCV) interface to pass  data  between
     TCP/IP  and  ADSM. Thus, other TCP/IP implementations that do not provide
     such an interface do not meet ADSM's requirements.

 o   The remaining clients all provide TCP/IP as part of their base  operating
     system.  ADSM will use such TCP/IP implementations without difficulty.

 SYSTEM.INI CHANGES NEEDED FOR PC/TCP IN THE WINDOWS ENVIRONMENT
 _______________________________________________________________

 The  Windows  environment  creates  a  file  in  the WINDOWS directory called
 SYSTEM.INI.  Within this file are segments by application program and windows
 function (e.g., BOOT, KEYBOARD).   Find the  section  labelled  (Vpctcp)  and
 change  the MinimumCopySpace variable to at least 32.  The default setting is
 sufficient to permit the ADSM client to backup files, but inadequate for file
 restores.  The symptoms of the problem are that the restore function hangs if
 there is too little copy space.
