Using SNAplus2 in a High Availability Environment
Using SNAplus2 with MC/ServiceGuard
Using the LAN to Access Standalone Servers
When SNAplus2 is used in a standalone configuration, the LAN can still
be used to access the server system. Although you do not run
applications on SNAplus2 client systems, you access the applications
running on the server from another computer system via the LAN. For
example, you might use telnet or rlogin to log in from a desktop
workstation to an SNAplus2 server to run the SNAplus2 application.
Like the TN Server example above, these TCP/IP connections will be
maintained during a local LAN failover or during a remote failover if you
access the server using the floating IP address associated with the
SNAplus2 package.
