Introduction to SNAplus2
SNAplus2 Components
preserved when the connection is re-established, do not make any
changes to the file in either domain while the LAN connection is broken.
Changes can still be made to the configuration of individual nodes.
SNAplus2 stores information about the master server and backup
servers in the file sna.net, known as the SNA network data file. The
master copy of this file is stored on the master server; any changes made
to it are automatically copied to all other servers in the same way that
changes to the domain configuration file are copied to backup servers.
You cannot edit the contents of the SNA network data file directly;
instead, SNAplus2 provides administration facilities to access the file.
(You can edit node configuration files directly when SNAplus2 is not
running; but in general you should use SNAplus2 administration
facilities to ensure that all configuration information is valid and
internally consistent.)
For more information about the SNA network data file, refer to the
HP-UX SNAplus2 Administration Command Reference.
HP-UX Clients
A client computer does not contain a configuration file or SNA network
data file. Instead, the client has a client network data file that holds the
information it needs to access servers on the SNAplus2 LAN. The client
relies on a server to provide the necessary configuration information.
Most of the details of using HP-UX client computers are the same as
those for a server, except that the client has no node resources to define
and manage. The following references provide more details about using a
client:
• To start and stop the SNAplus2 software, see Chapter 3,
"Administering SNAplus2."
• To set up information required to support invokable TPs on the client,
see "Defining TPs".
• To manage the SNA network information required to access servers
on the SNAplus2 LAN, see Chapter 11, "Managing SNAplus2
Clients," or refer to the HP-UX SNAplus2 Administration Command
Reference.
• To manage diagnostics information (logging and tracing), see
"Diagnostic Tools", or for more detailed information, refer to the
HP-UX SNAplus2 Diagnostics Guide.
