You can improve the performance of the business integration system by
distributing the connector agents. The reasons connector agent
distribution improves performance include the following:
- Each InterChange Server Express and connector agent process runs in its
own Java Virtual Machine (JVM). A computer can only have so many JVM
instances running on it before performance begins to degrade. The
threshold is dependent upon the computer specifications, but distributing a
connector agent decreases the load on the machine hosting InterChange Server
Express by one JVM.
- The performance of an individual connector generally improves the closer
it is to the application with which it communicates, with respect to the
network topology. Ideally the connector agent should be installed on
the same computer that hosts the application server itself, though this might
not be possible depending on the environment. If the application host
computer and the InterChange Server Express host computer are on different
subnets, however, the connector agent will typically still perform better if
installed on another computer in the same subnet as the one in which the
application host computer exists.
