Problem:

User attempts to create a new workspace in Modernization Workbench and receives "Cannot Create Workpsace" error.  The specific message returned is "The specified DSN contains an architecture mismatch between the Driver and Application".

Resolution:

The message can appear when there are conflicts between identically named DSNs used to define the data source.  In this case, the RMW_REPOSITORY DSN would exist at both the User and System level.  The issue can be resolved by using the System level RMW_REPOSITORY DSN in the Data Source used to connect to the Oracle database.
