Introducing the Intranet Process Manual
1 Introduction and
Organization
This manual describes the Intranet Process Manual configuration and gives
guidelines on how to administer the system. It also contains information that
will be useful to IT who may be managing server systems.
Client Machine
The Client Machine runs a standard Web Browser, such as Internet
Explorer. Internet Explorer 6 or 7 will give the best results when using the
system. As a minimum, the browser must support:
HTML 3.2
Frames
Javascript
Java applets
In addition there are two signed ActiveX controls that may be downloaded:
one for zooming images, and one for graphs. These are not essential to the
operation.
Server Machine
The bulk of the system resides on the Intranet Server. The major parts of the
system are:
Windows OS - 2000 Server or 2003 Server. Although the system can be
installed on Workstation versions of NT, 2000 or XP, these have a limited
number of allowed connections from clients compared to the Server
versions of these systems, and will only be suitable for a small user base.
Internet Information Server - this is the standard component bundled
with Windows 2000/2003 (although not necessarily installed by default).
The system has not been tested with other products that claim to support
ASP pages.
The Web Application, comprising a series of HTML and Active Server
Pages (ASPs) corresponding to the various pages that can be accessed by
the browser.
1 Introduction and Organization
7
The Document Server components deliver the content of the Process
Manual as HTML pages to the Web Application pages, and also handle
searching and equation solving. These components also access the license
pack files, which give the details of the system you have licensed.
Directories
Files are installed to subdirectories under a selectable base directory, which
defaults to Program Files\AspenTech\Aspen Process Manual <version
number>.
In the remainder of this document, paths will be referred to relative to this
base directory.
Administration Pages
These web pages allow the system to be reconfigured, and content integrated
with the server.
During installation, a shortcut to the administration pages should be installed
Start | Programs | AspenTech | Process Development
| Aspen Process Manual
| Process Manual Administration
but they can also be accessed by browsing to:
http://server/AspenTech/ProMan/proman.asp?page=admin

1 Introduction and Organization
2 Configuration
Internet Information Server
The Intranet Process Manual is installed as a web application within IIS. This
is done by creating a virtual directory under an existing web site; this
directory should be connected to the Aspen Process Manual <version
number>\Web directory.
The web application should be configured to have Enabled parent paths
selected (under Configure | Options in IIS).
We currently recommend running the application in a separate memory space
(high isolation level) to avoid conflicts with any other applications running.
We do not know of any such conflicts; we're just being cautious.
Licensing
The Process Manual is licensed by technical area. This information is stored in
a license file, which defines what parts of the system you are allowed to
access. Important: this file is linked to the security key, and will not operate
with another one.
It is possible to use licenses delivered from a network license server.
Refer to the Documentation DVD for further information on the AspenTech
licensing system.
2 Configuration

3 Web Application
The web application can be configured using the administration web page link
described earlier.
Through the administration web site (using the Admin | Configuration
menu), or through the Process Manual Administration program on the server
using the Configure | Web application menu.
This web page is divided into a number of sections.
10
3 Web Application
Links
This section contains two buttons. One transfers back to the normal welcome
page, and one displays additional debug information.
If you request support from AspenTech, you will probably be asked to provide
a copy of the debug page, as this contains information on how the system is
configured and operation.
Document server settings
This section indicates the root folder used to search for documents included in
the system. This is configured automatically at installation time.
The Re-index documents button causes the document server to re-scan this
folder (and sub-folders) for content to be included, and build an appropriate
high-level index. This needs to be done on first installation, and if the
documents are subsequently updated.
3 Web Application

Contact information
This section contains information which appears on pages displayed to the
user. Enter the appropriate settings and click on the Update contact
settings to save the values.
Performance and configuration
The settings control how content is rendered to users.
A description of each setting is included on screen.
Adjust the settings as required, and click on the Update performance and
configuration settings button to save them.

4 Troubleshooting
If you have problems with system operation and wish to contact Support, it
would be helpful to include information on your system configuration.
Go to the Administration page, and click on the Display debug and status
information button. This should display a page of status information; please
save and attach or copy/paste into any email to our support staff. This will
help us to understand your specific configuration and may speed up our reply.
