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 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 illustrates a NonStop TS/MP application server class distributed across two

nodes. The application checks accounts and updates it using batch processing. The

batch requester process and a server class are configured on \NODEA while a second

server class is configured on \NODEB. Both \NODEA and \NODEB are connected over

communication lines. Additionally, there are two PATHMON processes (one on each

node) managing the server classes at their respective nodes. The requester process

on \NODEA connects to the server class on \NODEB using the LINKMON process

running on the same processor as that of the requester process on \NODEA. The

LINKMON processes on \NODEA communicate with the PATHMON process on

\NODEB to find a link to the server class running on \NODEB.

Note. TS/MP 2.3 does not support a NonStop TS/MP application server class distributed

across two nodes.
