MICROSOFT SQL SERVER SUPPORT FOR OS/2 2.1

Microsoft SQL Server version 4.2 for OS/2 is supported on
OS/2 versions 1.3 and 2.1.  Although typically used in multi-
user environments, the server is designed to allow stand-
alone operation so that no networking software is required
for single-user operation.  In the more common multi-user
environment, the server relies on networking software, such
as Microsoft LAN Manager version 2.2, to provide
interprocess communication services.

Microsoft SQL Server 4.2 is currently supported on OS/2 2.1
as both a client and server platform in IBM and Novell
network environments.  It may also be run in a stand-alone,
single-user configuration without any network software.
However, for most sites it is recommended that you use OS/2
version 1.3, which ships with SQL Server, as the preferred
operating system for the server software.  OS/2 version 1.3
is stable and is widely supported in all LAN environments.

SUPPORT FOR WINDOWS-BASED APPLICATIONS

It is recommended that you run Windows-based applications in
their native environment, on Microsoft Windows version 3.1.
However, Windows-based applications that access SQL Server
will run on OS/2 version 2.1 as long as you are using LAN
Manager version 2.2 or IBM LAN Server version 3.0.  Internal
testing has not found Windows-based applications on OS/2
version 2.1 to be a platform stable enough to recommend with
other networking software.

NETWORK COMPATIBILITY

Microsoft SQL Server can operate on OS/2 version 2.1 as both
a client and server platform with the following network
software:

  o IBM LAN Server version 2.0 (Entry System) or version 3.0
  o Novell NetWare Requester for OS/2 version 2.01

In addition, SQL Server is supported as a client with the
LAN Manager 2.1 Productivity Pak, and with LAN Manager 2.2,
which supports OS/2 2.1 clients.

With the appropriate network configuration, SQL Server on
OS/2 2.1 is interoperable with components running on OS/2
1.3. (For example, an OS/2 2.1 - based client can access SQL
Server running on OS/2 1.3. Or OS/2 1.3 - , MS-DOS - , or
Microsoft Windows - based clients can access SQL Server
running on OS/2 2.1.)

MEMORY USE AND PERFORMANCE

When both the computer hardware and the networking software
support addressable RAM greater than 16 MB, SQL Server can
take advantage of additional physical memory when running on
OS/2 2.1 (Note, however, that OS/2 2.1 itself uses more
memory than OS/2 1.3).  For information about the ability to
address greater than 16 MB of physical RAM with OS/2 2.1 in
your environment, consult your hardware manufacturer or IBM.

Microsoft internal testing has found that SQL Server running
on OS/2 2.1 is typically slower and uses more memory than
SQL Server running on OS/2 1.3.  These results are from pure
on-line transaction processing (OLTP) tests.  The ability to
address more cache memory might be more useful for query-
intensive applications operating against very large
databases. Note that your "mileage" may vary.

Other Considerations When Running on OS/2 2.1

When considering running SQL Server on OS/2 2.1, be aware of
the following considerations (note that this information is
based on internal testing by Microsoft and is subject to
change as newer releases of components are made available):

  o There is no separate version of SQL Server for OS/2 2.1.
    SQL Server 4.2 is compatible with both OS/2 1.3 and
    2.1.
  o When running SQL Server setup, use the "Non-LAN Manager"
    installation option.
