Prevent Derby from installing/running

Postby techypaul » Wed Dec 27, 2017 4:50 pm


Is it possible to remove Derby entirely, or prevent it from running?

Code: Select all

2017-12-27 15:39:24,620 [localhost-startStop-1] INFO - Using JDBC connection: jdbc:derby://localhost:22649/databases/profiler;create=true (org.apache.derby.jdbc.ClientDriver)

Wed Dec 27 15:39:24 UTC 2017 : Could not connect to Derby Network Server on host, port 22649: Connection refused (Connection refused)
Wed Dec 27 15:39:24 UTC 2017 : Apache Derby Network Server - - (1616546) started and ready to accept connections on port 22649
2017-12-27 15:39:25,283 [localhost-startStop-1] INFO - Apache Derby started

We're using MySQL and Derby is unwanted.

Hi Paul,

Thank you very much for your question. In fact, the Derby instance that you can see in the log file has been initialized for CloverETL Data Profiler.

This application is maintained independently from the CloverETL Server and a separate database is created for it by default. Even though you are using MySQL DB for CloverETL Server, the CloverETL Profiler is still using the default Derby DB.

Once neither the Server nor the Profiler uses the Derby DB driver, there is no need to disable the unused Derby database explicitly, the Derby shouldn't start on its own.

For more information about how to configure Data Profiler DB please see the following page:

I hope the information provided was helpful. Should you have any additional questions, don't hesitate to ask. Have a nice day, Eva
