Using SNAplus2 in a High Availability Environment
Using SNAplus2 with MC/ServiceGuard
capability. Following are four different ways in which applications can
gain SNA network connectivity through an SNAplus2 server using a
LAN.
SNAplus2 Client/Server LAN Connections
As described above, SNAplus2 can use either a standalone or a
client/server configuration. In a client/server configuration, you run
applications on client systems (HP 9000s or PCs) that access an
SNAplus2 server through the slim process running on the server
system.
Figure D-7 SNAplus2 in Client/Server Configuration
SNAplus2 uses an internal mechanism to inform applications running on
client systems about the IP addresses they should use to access each
particular server. This mechanism does not forward information about
the IP address associated with the SNAplus2 package, so clients will use
only the sta tionary IP address associated with the server’s LAN adapter.
