Management in NSJSP
iTP Secure WebServer Online-Upgrade Configuration
Considerations for NSJSP
In a single PATHMON environment, the iTP Secure WebServer creates the NSJSP
Server Class as defined in the conf/servlet.config file within the NSJSP
installation directory. However, if the iTP Secure WebServer is configured for online-
upgrade, that is with two PATHMONs in a Pathway domain, the PATHMON
configuration is handled differently. The iTP Secure Webserver defines the server class
for both Pathmons, but also divides the NSJSP Server Class configuration between the
two PATHMONs. One half of the NSJSP Server Class will be configured in one
PATHMON and the other half will be configured in the second PATHMON.
Management in NSJSP
Starting with the NSJSP 6.1 release, the NSJSP Manager application has been
included. The NSJSP Manager enables single point management of all NSJSP
installations within the iTP Secure WebServer environment. The following are some of
the important tasks that you can perform:

Dynamically deploy user web applications on an active NSJSP installation. Also,
you can dynamically deploy an application on all the server class processes in an
iTP Secure Webserver Pathway domain.

View application statistics. You can obtain detailed information about applications,
such as, the distribution of application requests across NSJSP Server Class
processes and the time taken to process requests.

View server class statistics, which you can use to tune the server class
configuration. You can also perform tasks, such as start and stop the NSJSP
Server Class. The NSJSP Manager provides detailed status and statistics of the
server class processes.

Manage the Servlet Container Components from the admin feature and persist the
changes made in the configuration files.
Starting, Stopping, and Restarting the iTP Secure WebServer
Because NSJSP installations are created in an iTP Secure WebServer environment,
when the iTP Secure WebServer environment is stopped, started, or restarted, all the
NSJSP installations in the iTP Secure WebServer environment are also stopped,
Note. You can also deploy a web application to the NSJSP Server Class processes by
copying the .war file of the application to the webapps directory of the NSJSP installation
or by copying the application directory, subdirectories, and files to the webapps directory
of the NSJSP installation.
Note. Because NSJSP processes run in TS/MP server classes, you can also use
PATHCOM and PDMCOM to view the status of server class processes or to display server
class statistics.
