Distributing a Pathway or PATHMON Environment

Depending on the requirements of your application, you might distribute a Pathway or

PATHMON environment over several processor in a single NonStop system or among

several NonStop systems.

One way to optimize response time for your business transactions might be to

distribute your application’s workload across more than one processor in a NonStop

system. Figure 1-3 on page 1-6 shows PATHMON-controlled objects configured on

two CPUs in a system. This environment includes both NonStop TS/MP processes

(PATHCOM, PATHMON process, server classes) and Pathway/iTS processes (TCPs

and TERM objects).

You can distribute functions over different physical or geographical locations by

configuring elements of a single PATHMON environment on various nodes in a

network connected by communications lines, or by configuring two or more PATHMON

environments to communicate across such a network. As an example, you can enable

TCPs on one node to access a database maintained by server processes on another

node. This configuration allows multiple applications on different nodes to share data.

Figure 1-4 on page 1-7 shows a NonStop TS/MP application distributed across two

nodes. The application updates checking accounts using batch processing. The batch

requester process is configured on \NODEA along with PATHCOM, a PATHMON

process, and the LINKMON process. One server class is also configured on \NODEA.

The requester process forms a link across a communications line to the PATHMON

process and server classes on \NODEB. The link is managed by the LINKMON and

PATHMON processes.
