NSJSP Features

Starting with the NSJSP 6.1 release, you can install and manage NSJSP in an iTP

Secure WebServer 7.0 environment that is configured for online-upgrade.

For more information on the online-upgrade feature, see An iTP Secure

WebServer Environment Configured for Online-Upgrade on page 1-6.

Figure 1-6 illustrates NSJSP in an iTP Secure Webserver environment that is

configured for online-upgrade.

In Figure 1-6

, $zweb and $yweb denote two PATHMONs configured in a Pathway

domain. The iTP Secure WebServer and the NSJSP installations are distributed

across both PATHMONs. The NSJSP processes running in the Servlet Server

Class are divided between the two PATHMONs. User requests can be routed to

the processes under each PATHMON. If one PATHMON needs to be upgraded or

if the processes in one PATHMON are stopped, the processes in the other

PATHMON can continue to service the requests, thereby ensuring that NSJSP

application services are continuously available.
