# Verifying ColdFusion Data Sources

The ColdFusion Administrator includes a facility for verifying data sources configured for ColdFusion, that is, making sure that a data source has been correctly configured and is available to your ColdFusion application pages.

Note | You may need to supply a username and password for the data sources you want to verify. To define a username and password for a data source, edit the properties for the data source.

| To verify a ColdFusion data source:

1. Open the ColdFusion Administrator
2. Under Data Sources, select Verify Data Sources.

   You see a list of all the ColdFusion data sources on the server.

3. To verify all the data sources listed on the page, click Verify All.

   The word "Verified" appears next to each data source that ColdFusion successfully verified and the word "Failed" appears next to each data source that ColdFusion could not verify.

4. To verify an individual data source, click its name.

   ColdFusion displays a message that tells you whether or not the data source was successfully verified.

Note | If ColdFusion is unable to verify a data source, you might find it useful to run a CFQUERY against the failed data source to get more detailed information about the problem.
