Administering SNAplus2
Enabling and Disabling SNAplus2 on the Local System
tracing.) Tracing enables you to diagnose problems that
occur during startup. If you do not use this option,
tracing is inactive at all interfaces; you can then
activate it on specific interfaces as required, using the
command-line administration program
snapadmin
.
Tracing on all interfaces degrades the performance of
SNAplus2 components. After the software is enabled,
you can use the command-line administration program
snapadmin
to stop tracing on any interfaces where it is
not required. For more information about tracing, refer
to the HP-UX SNAplus2 Diagnostics Guide.
SNAplus2 writes messages to standard error (normally your terminal's
screen) to indicate that it is initializing, and to indicate whether
initialization completes successfully.
If initialization fails, the messages include information about the cause
of the error, and (where appropriate) additional information such as the
HP-UX operating system error message. The text written to standard
error may also include a message indicating that you can find further
information in the error log file. The
snap start
command then ends
with a nonzero exit code that indicates the nature of the error.
For more information about exit code values, refer to the HP-UX
SNAplus2 Diagnostics Guide.
Disabling SNAplus2 Servers
Disabling the SNAplus2 software on a server automatically stops the
SNAplus2 node and its associated connectivity components. Disabling
SNAplus2 also stops any other processes (such as a 3270 emulation
program) from using SNAplus2 resources on this server.
In general, you should stop individual services as users finish using
them, and only disable the system when there is no SNAplus2 activity.
Disabling the SNAplus2 software on a client stops any programs running
on the client from accessing SNAplus2 facilities.
If you need to disable SNAplus2 while users are active, warn users that
SNAplus2 is stopping, and give them time to finish their activities before
you disable the software. Use the Motif administration program or the
command-line administration program to view details of active users.
