CSP Gateway Configuration Guide - InterSystems Documentation

Using the Network Service Daemon (NSD)
• Stop the NSD service if it is running.
• Continue the NSD service if it is paused.
• Remove the NSD service from the services database.
Alternatively, you can use the Windows Service Manager to manage the NSD. The NSD can be identified in the Service
Manager by the description:
Cache Server Pages – Network Service Daemon
All errors are reported in the CSP event log (that is, CSP.log). This file is created and maintained in the install-dir\csp
directory. The CSP configuration file CSP.ini also resides in this directory.
Other Startup Options
1. Display help information.
CSPnsd -h
2. Run the NSD interactively in a command window as opposed to as a Windows service. This mode of operation must
be used if multiple instances of the NSD are to be run.
CSPnsd -v
A.1.3.1 Starting NSD on Alternative TCP Port
By default, the NSD listens for incoming requests on TCP port 7038. You can override this by starting the service as follows:
CSPnsd –v [port_no]
Or:
CSPnsd –v -p[port_no]
- where port_no is the TCP port number of your choice.
On startup, the NSD creates the following file:
CSPnsd.ini
Typically, this file contains the following lines:
[SYSTEM]
Ip_Address=127.0.0.1
TCP_Port=7038
In this context, the clients are the CSP modules contained within, or dynamically linked to, the web server and/or the CSP
CGI modules invoked by the server. It is, therefore, essential that this file is not deleted or moved. It is also important that
the web server processes can read this file. Set the privileges accordingly, bearing in mind the Windows user under which
your web server is operating. The NSD clients attempt to find this file in a location contained within the Windows PATH
variable. For example:
\Windows
The CSPnsd.ini file must be moved to this location before starting the web server
Clearly, storing the NSD port number in the CSPnsd.ini file is inappropriate for situations in which multiple instances of
the NSD are running. For Apache servers, there is a much better mechanism for communicating the TCP port number of
the NSD to its clients.
Set the following environment variables in the Apache configuration to indicate the address and port of the target NSD
installation. The values specified in these environment variables take precedence over any values found in the CSPnsd.ini
file.
