Starting and Setting Up RTR
2.4 Changing a Facility
Example 2–4 Reconfiguration Using Extend Facility
% RTR
RTR> start rtr /node=(TR3,FE4)
RTR> set environment/node= -
1
_RTR> (FE1,FE2,FE3,TR1,TR2,BE1,BE2,BE3,TR3,FE4)
RTR> extend facility funds_transfer - 2
_RTR> /router=TR3/frontend=(FE3,FE4) -
_RTR> /backend=(BE1,BE2,BE3)
RTR> extend facility funds_transfer - 3
_RTR> /router=TR1/frontend=FE4
1 The set environment is used to send the following command to all nodes in
the facility, including the new nodes.
2 The extend facility defines the new router TR3 and the new frontend FE4.
Because the new router is also connected to the existing frontend FE3, this
node must also be specified as a frontend. The new router TR3 is told about
all backends with the /backend qualifier. Note that the
extend facility
command has been used to create new definitions on TR3 and FE4, and
extend the definitions on BE1, BE2 and BE3.
3 The extend facility command is used to extend the definitions on TR1 and
FE4 in order to give FE4 a second router link.
2.5 Setting up Callout Servers
Callout servers are applications that receive a copy of every transaction passing
through the node where the callout server is running.
Like any other server, callout servers have the ability to abort any transaction
that they participate in. Callout servers are typically used to provide an
additional security service in the network; transactions can be inspected by the
callout server and aborted if they fail to meet any user-defined criteria. Callout
servers can run on router or backend nodes, or both.
Assume that callout servers are to run on the router nodes (TR1 and TR2) in the
example configuration shown in Figure 2–1. Example 2–5 shows the commands
needed to set up callout servers on the routers.
