Upgrade of Data Loader from version 36 to 38, scripts.

Hi Everyone, 

I will like to upgrade my version of data loader from v36 to v38, I had allready installed the new version, but for the batch process I have the following error:

Hi Monica,

Please make sure that the classpath knows where the driver files are.  If you're using the batch command line then you can do that using the -classpath parameter e.g
 
java.exe -classpath ..\DataLoader.jar;"c:\program files\Microsoft SQL Server 2000 Driver for JDBC\lib\msbase.jar";"c:\program files\Microsoft SQL Server 2000 Driver for JDBC\lib\msutil.jar";"c:\program files\Microsoft SQL Server 2000 Driver for JDBC\lib\mssqlserver.jar"
etc 

Please refer below link for the same.

Hope this helps you!

If this helps you, please mark it as solved.

Thanks and Regards

Hi Sandhya, 

Sorry, but no, I remain with the error, and sorry I copy the wrong message, with the changes I made in the script for the upgrade, the error that it's giving me is the next one:

Thank you, Regards

The error which you are receiving  "Cannot load JDBC driver class " seems like the Path of your JDBC driver is not accessible. There are some links which will help you to understand the issue or concept.  Download the appropriate JDBC Driver from here:

http://www.oracle.com/technetwork/database/features/jdbc/index-091264.html

So if using Oracle 11g R2, then they would download ojdbc6.jar. Place it into the same folder as the process.bat file, then modify the process bat to add a reference to it in the -cp parameter. Like so:

..\Java\bin\java.exe -cp ..\dataloader-25.0.0-uber.jar;ojdbc6.jar

This ensures that driver is available when needed.

Thanks and Regards
