When connecting to a Cache database with Fast Data Masker (FDM), we are receiving the following error message: 
class not found:com.intersys.jdbc.CacheDriver 

We have added the Cachejdbc.jar file to the FDM lib directory folder (C:\Program Files\Grid-Tools\FastDataMasker\lib) and we are choosing the DBMS CACHE when connecting. 

CA Test Data Manager (TDM)- Fast Data Masker (FDM)

Some of the classes FDM relies on had been refactored from the cachedb.jar to the new cachejdbc.jar. FDM needed to be modified to reference both jars in the lib directory folder. 


Make sure you have either the cachedb.jar or the cachejdbc.jar file in C:\Program Files\Grid-Tools\FastDataMasker\lib. 

We highly recommend upgrading to the latest version of Test Data Manager, which includes the latest FDM build where the issue has been fixed. Directions to do this are listed here:

If you are using FDM 4.6.3 or below, there is an available patch you can apply. Please open a support case referencing this document, TEC1254728, and we will supply this. You can open a support case by going to
