Why do I get an exception when transferring large amounts of data with the JDBC-ODBC Bridge?

When attempting to transfer large amounts of data (30-40 MB), you may get the following error:

sql.SQLException: [JDBC-ODBC Bridge] RPC Exception RPC_ERROR_BAD_START.

There is a default limit on the size of data that the Easysoft JDBC-ODBC Bridge can get from a back end. You can change this limit by adding the JDBC URL connection attribute:

:mb=float

where float is the number you want to increase the limit to.

For example, to specify a 40 MB limit:

:mb=40.0
