Connection Mapping

Revision as of 12:33, 13 August 2014 by Antonio.remedios (talk | contribs) (Added information about SQL)

XLCubed Web Edition supports the re-targeting of connections for reports published to the web server.

To enable this feature, the ConnectionMapping.xml file must be created in the Xml subfolder of the XLCubed Web installation folder. This file can contain:

  • one or more connectionmap nodes (for cube connections) each of which must contain a from connection definition and a to connection definition
  • one or more sqlconnectionmap nodes (for relational connections) each of which must contain a match Regular Expression element and a connectionstring to replace it

After modifying this file, IIS must be restarted.

When a user loads a Report to view, the Web Edition will automatically search for any connections matching a from or match definition, and replace them with the corresponding definitions. For cube connections, the match is done using the Type, Server, Database and Cube of the from connection.

The ID number and name for the connection will be left unchanged.

Example XML file

This example:

  • matches cube connections to the DEVELOPMENT server and replaces them with connections to the PRODUCTION server
  • matches SQL connections to any of the servers DEVELOPMENT1, DEVELOPMENT2 and DEVELOPMENT3 and replaces them with connections to the PRODUCTION server
