iTP Secure WebServer httpd
the listening role (as opposed to one per processor in Parallel Library TCP/IP and
TCP/IPv6).
iTP Secure WebServer httpd
The iTP Secure WebServer httpd has two main functions:
•
A file server. The httpd process transfers and stores files, such as HTML
documents.
•
A message-switching facility. The httpd process forwards messages from Web
clients to application programs.
The httpd process is implemented as a server class in NonStop TS/MP. Therefore
multiple httpd processes can execute in parallel; the number of processes fluctuates
automatically in response to changes in workload. NonStop TS/MP can also restart a
server process that fails. (The iTP Secure WebServer uses the default value of the
PATHCOM AUTORESTART parameter.)
PATHMON Process
The PATHMON process provides centralized monitoring and control of a PATHMON
environment consisting of server classes and other types of objects. You establish the
operational parameters for the PATHMON environment, including the characteristics of
individual server classes, by creating a PATHMON configuration file. Thereafter, you can
use the PATHCOM utility to make configuration changes and obtain information from
the PATHMON process.
Multiple PATHMON environments can run on the same NonStop system. For example,
the iTP Secure WebServer Administration Server has its own PATHMON environment,
separate from the iTP Secure WebServers environments it manages. (If you have
multiple iTP Secure WebServer environments on the same system, you still need only
one PATHMON environment for the Administration Server.) Each PATHMON environment
has a separate, uniquely named PATHMON process.
WebSafe2 Interface Driver (WID)
A WID is required when you are using the WebSafe2 unit to perform hardware
encryption.
Active Transaction Pages (ATP)
Active Transaction Pages (ATP) provides a server-side JavaScript environment for HP
NonStop Systems. You can use ATP objects to provide Web-based interfaces to
existing NonStop TS/MP, NonStop TUXEDO, NonStop SQL/MP, and sockets
applications.
Note. WID is compatible only with systems running on G-series RVUs.
