Configuration

All BcsService configurations are stored in the DigaSystem registry in the subkey "BcsService". If only one configuration is defined, it will be used automatically when the BcsService is started. In the following figure, there is only one configuration "Local".

If more than one configuration is specified, the desired configuration must be specified. Each configuration is stored in its own subkey which is named after the configuration name that was provided in the installation process. See Using multiple configurations for details.

In the following figure, there are two configurations "Config1" and "Config2".

Configurations can be stored in the global and in the local registry. Both registries are scanned but the local registry has priority over the global registry.

Logging

Since BcsService version 3.2, the standard DigaSQL logging mechanism is used. To enable the logging for a specified configuration, set the variable with the name "BcsService-ConfigurationNameHere" in the "Protocol" subkey of the DigaSystem registry.

If any error occurs before the DigaSQL log is initialized (e.g. configuration with specified name not found) than the standard Windows Application log is used. This means if BcsService does not start, check the Windows Application log for any messages.

Windows log

BcsService uses the standard Windows log (Windows Application log) for logging if the DigaSQL isn't accessible. E.g. before the DigaSQL initialization or if the DigaSQL initialization failed. All Windows log entries show the configuration name in the source field, e.g. BcsService_Config1. That simplifies the analysis if BcsService is installed with multiple configurations.

Be aware! When using special characters (at least space and - ) in the configuration name, Windows interprets them as separators and stores only parts of the name in the source field of the Windows log.

E.g. for a configuration with the name VM-Station-2020-BCS the source field will store only 2020-BCS instead of BcsService_VM-Station-2020-BCS. To avoid that, don't use any special characters in configuration names.

DigaSystem registry subkeys and parameters

BcsService\ConfigurationName

Parameter name

Description

LogLevel

Determined how much details will be stored into log for this configuration. Only followed values can be specified otherwise error occurred

Critical - only very important messages will be logged. Errors aren't included
Error - very important messages and all errors are logged
Warning - very important messages, errors and warnings are logged
Information - very important messages, errors, warnings and verbose messages (include HTTP & WebSocket API calls) are logged. Warning! This level can generate large log files. Enable it only if you want to log all API calls on BcsService side
Debug - all messages (included HTTP & WebSocket API calls) and special information for support are logged. Warning! This level generate very large log files. Enable it only if it requested from support

Default value
Error

BcsService\ConfigurationName\BCS

Contains parameters affected to linked BCS

Parameter name	Description
Name	BCS (not workstation!!!) name from DigaSystem registry in key "Digas\PlanServer\NameHere" Example: LocalBCS
BcsUser	Identity under which the service connects to the BCS server for internal tasks. User should have rights to read all programs metadata Example: Admin
BcsPassword	Password for the identity encrypted in BCS format. Example: ****
PollingInterval	Polling interval (milliseconds) for checking active connections from clients. If all connections under with specified BCS user are inactive more as this interval than connection to BCS will be closed and all clients used this user name should be login by BCS again. Default value 60000

BcsService\ConfigurationName\Database

Contains database service parameters

Parameter name

Description

DatabaseUser

Identity under which the service connects to the DigaSQL database. User should have rights to read all used tables.

Example:
Admin

DatabasePassword

Password for the identity to the DigaSQL database encrypted in BCS format.

Example:
****

BcsService\ConfigurationName\FileCopy

The parameters of this key define the behavior of BcsService regarding when or when not to copy files into media directories. For a description of the individual parameters see the key "DigAIRange\FileCopy".

BcsService\ConfigurationName\Paths

Contains path to affected locations

Parameter name	Description
MediaFolder	Folder where temporary stored received media files Default value: BcsService_Directory\Media\ Example: D:\Media\
HtmlFolder	Local path with data for HTML streaming. E.g. install WebDigAIRange into this folder to using BCS Service as host for WebDigAIRange Default value: BcsService_Directory\Html\ Example: D:\Html\
MediaFolder0 MediaFolder1 ... MediaFolderN	Optional parameters in any count to provide file access via BCS Service. By default BCS Service restricted any file access to followed locations Directory from MediaFolder parameter (see above) and all subdirectories Directory from HtmlFolder parameter (see above) and all subdirectories BCS media directories and all subdirectories To provide file access via BCS Service to any other directories with all subdirectories define it in extra parameters MediaFolder0...N If any parameter value is empty it's ignored. Example: \\fileserver\extra\audio\

BcsService\ConfigurationName\Paths\AllowList

Contains optional directories in any count to provide file access via BCS Service.

Parameter name

Description

AllowFolder0
AllowFolder1
...
AllowFolderN

Optional parameters in any count to provide file access via BCS Service. By default BCS Service restricted any file access to followed locations

Directory from MediaFolder parameter (see above) and all subdirectories
Directory from HtmlFolder parameter (see above) and all subdirectories
BCS media directories and all subdirectories
Database media directories and all subdirectories

To provide file access via BCS Service to any other directories with all subdirectories define it in extra parameters AllowFolder0...N
If any parameter value is empty it's ignored..
Deny list is more important as allow list. This means if the same path is present in the both (allow & deny) lists than file access will be denied, because of deny access has more priority as allow access.

Example:
\\fileserver\extra\audio\

BcsService\ConfigurationName\Paths\DenyList
