The Isentris Data Source Builder (DS Builder) might fail to validate an Integrating Datasource (IDS) if the Oracle database that hosts the underlying IDS data is setup with the JA16SJIS character set. With such a configuration, users may receive an error 'Invocation Failed' after clicking the 'Validate' button in DS Builder.

Customers that are impacted by this problem can resolve the issue with the following steps:

1. Make a backup copy of the file 'DataSource.isentrisService.xml' that is located in the '[...]\system\launchpad\services' folder of your Isentris installation directory.
2. Open the file in a text editor and locate the CLASSPATH line:  classpath=".;./lib/IsentrisDataSourceService.jar"
3. Modify this line to include the JDBC driver files including NLS support: classpath=".;./lib/IsentrisDataSourceService.jar;./lib/ojdbc8.jar;./lib/orai18n.jar"
   
4. Save the modified file, and restart the Isentris services.
