Central Configuration

PrizmDoc Server can be configured using a central configuration file for both Windows and Linux. To do so, watchdog.config must contain a property paths.central_config_file whose value is a path to the central configuration file relative to the PrizmDoc Server install directory. If this value is not provided, legacy configuration will be used instead.

The configuration file will perform environment variable expansion in path values. The environment variable must be contained within a quoted string and enclosed with the % character. For example, "%ALLUSERSPROFILE%" or "%my_path%/subpath" are both valid paths containing environment variables which will be expanded at runtime.

The following options are available for configuration within the central configuration file:

Licensing

Property	Default Value	Supported Values	Description
license.solutionName	None (Required)	Valid solution name string	PrizmDoc Server solution name.
license.key	None (Required)	Valid license key string	PrizmDoc Server license key.

Network

Property	Default Value	Supported Values	Description
network.publicPort	None (Required)	Any open HTTP port on the server	The public port the REST API will be available on.
network.internalStartingPort	None (Required)	Any open HTTP port on the server	The product requires a range of 200 ports which are reserved for its own internal use. This setting defines the starting port of that range (e.g. a value of 19000 means that ports 19000 through 19199 would be reserved for use by the product). These ports must not be accessible from outside of the server, for security reasons.
network.clustering.enabled	false	true, false	Set to true to enable multi-server mode.
network.clustering.clusterPort	-	Any open HTTP port on the server	The port used to route requests to other servers in the cluster. This port needs to be exposed to the other servers in the cluster.
network.clustering.servers	-	Array containing hostnames or ip addresses of other servers within the cluster.	The server list can be set once via config, or repeatedly at runtime via a REST API call. Setting the list of servers here is useful if you have a static set of machines that will not change.

Security

Property

Default Value

Supported Values

Description

security.aesEncryption.key

"E9rU73lZ2vd0he8Ls/hD8A=="

Base64 encoded value of a byte array representing an AES key with a size of 128, 192 or 256 bits.

The AES encryption key used to create external viewing session IDs. The external viewing session ID is a AES encrypted, Base64 encoded value of a string in the format of:

Internal ID: This value is a unique GUID that is internally created by PCCIS for each new viewing session.

Server’s Host Name: Aptly named, this value is the hostname of the server on which PCCIS is running.

Auth-Token Header Value: If the "Auth-Token" HTTP header exists in the initial POST request to create a viewing session, its value will be used here. Otherwise, "accusoft" is used. This value is useful if you have the need to store an authorization token for each viewing session which a proxy might need.

See PrizmDoc Multi-Server Mode for more details.

This option is available for PrizmDoc version 12.0 or greater.

Fidelity

Property	Default Value	Supported Values	Description
fidelity.svgMaxImageSize	8000	Any integer greater than 0	For source documents which contain images, ensures that the images in the SVG delivered to the browser do not exceed a particular pixel width and/or height. For example, a value of 8000 would ensure that any images in a PDF whose width or height were greater than 8000 pixels would be down-sampled before the image was added to the final SVG. A typical value is 8000. The default value for this property is configurable. The out-of-box configuration uses a default value of 8000. Use 0 to disable the optimization.
fidelity.vectorBackgroundColor.view.default	white	CSS color name, e.g. "gray", or a hex RGB value, e.g. #FFFFFF	Defines the background color for viewing CAD documents if the background is not specified in the document. Also defines the background color for converting CAD documents to SVG, PNG, JPEG and TIFF. Please note, DGN documents define their background color, so this property does not affect them. Use fidelity.vectorBackgroundColor.view.override to define background color, ignoring the background color specified in the document.
fidelity.vectorBackgroundColor.view.override	none	CSS color name, e.g. "gray", or a hex RGB value, e.g. #FFFFFF, or “none”	Defines the background color for viewing CAD documents, ignoring the background specified in the document. Also defines the background color for converting CAD documents to SVG, PNG, JPEG and TIFF, ignoring the background specified in the document. Overrides fidelity.vectorBackgroundColor.view.default.
fidelity.vectorTolerance	0.3	A positive Floating point value with a minimum value of 0.0 and a maximum value of 10.0	For CAD documents, controls how much path simplification is allowed. The path simplification algorithm will merge points which are "close together" to create an optimized SVG. You can think of this value as defining what "close together" means. A typical value is 0.3. Higher values introduce more simplification, but also more distortion. The value cannot be greater than 10.0. The default value for this property is configurable. The out-of-box configuration uses a default value of 0.3. Use 0 to disable the optimization.
fidelity.msOfficeDocumentsRenderer	"auto"	One of the following strings: "auto", "libreoffice", and "msoffice"	Specifies the renderer to use with Microsoft Office documents. When set to "auto", PrizmDoc decides which renderer to use based on the MSO feature license state. If the MSO feature is present, then the Microsoft Office renderer will be used. Otherwise, Libreoffice will be used. When set to "libreoffice", PrizmDoc will be using the Libreoffice renderer. If you are intending to use the Libreoffice renderer permanently on a server that does not have Microsoft Office installed, please contact Accusoft Sales or Customer Support, to obtain the license key with MSO feature disabled. When set to "msoffice", PrizmDoc will be using the Microsoft Office renderer, if the MSO feature is enabled in the license key, otherwise the licensing error will be reported. The parameter affects only Microsoft Office documents, RTF and CSV files. Other documents will continue to be rendered with LibreOffice. For a complete list of supported file types see Supported File Formats.
fidelity.msOfficeCluster.host	""	A valid IP address or hostname	This value is used to enable Microsoft Office Conversion connectivity for PrizmDoc servers running on Linux. Set this value on a PrizmDoc server running on Linux to the hostname (or the IP of a single PrizmDoc server, or a load balancer of a cluster running on Windows) to utilize the Microsoft Office Conversion service running on Windows to have native rendering of Microsoft documents in PrizmDoc.
fidelity.msOfficeCluster.port	0	Any open HTTP port on the server	This value is used to enable Microsoft Office Conversion connectivity for PrizmDoc servers running on Linux. Set this value on a PrizmDoc server running on Linux to the public port of a single PrizmDoc server (or a load balancer of a cluster running on Windows) to utilize the Microsoft Office Conversion service running on Windows to have native rendering of Microsoft documents in PrizmDoc. To connect to a single server specify 'network.publicPort' parameter of the remote server. To connect to a load balancer specify 'network.clustering.clusterPort' parameter of the cluster.
