Linking to a remote DB Provider with Studio Database Gateway
Depending on the architecture of your project, the ADO.NET Provider for the SQL Relational Database may not
be available in the same stations where IWS is running. This scenario is especially common when the
application is run on the Windows CE operating system (currently, most Providers don not support the Windows
CE operating system). In order to solve this problem, InduSoft designed a flexible solution that allows you to
configure distributed systems, as illustrated in the picture below:
The application is running in the Studio Application station where IWS (or CEView) is installed. The application
can communicate with the Studio database gateway (running in a remote computer) via TCP/IP. The Gateway
implements the interface with the Database through the Database Provider available in the computer where it is
running.
The Studio database gateway does not require complex configuration. Just copy the files STADOSvr.exe and
StudioADO.ini from the \BIN sub-folder of IWS and paste them under any directory of the computer that will be
used as the Gateway station and execute the STADOSvr.exe program. There are advanced settings associated
with the Studio Database Gateway, but they should be changed only under special circumstances. See the
topic “Studio Database Gateway” for information on how to configure the Studio Database Gateway advanced
settings.
Notes:
• The Studio database gateway is a TCP/IP Server for the IWS application and it uses the TCP Port
3997 by default. You can specify a different port number when executing the STADOSvr.exe
program according to the following syntax: STADOSvr.exe . Example: STADOSvr
3998
• Be sure the TCP/IP Server is enabled during runtime (Project Status Execution Tasks. Be
sure the TCP/IP Server is set to run automatically.
