Make sure that the data source you want to delete is not used by a
multi data source. If the data source you want to delete is used by a
multi data source, you must remove the data source from the multi data
source before the data source can be deleted. The delete operation will
fail if the data source you are attempting to delete is used by a multi
data source. See Add or remove
data sources in a JDBC multi data source

Services > JDBC, then select Data
Summary of Data Sources page, select the check
box for the data sources that you want to delete.
Delete and confirm the deletion.
To activate these changes, in the Change Center of the Administration Console, click Activate Changes. Not all changes take effect immediately—some require a restart (see Use the Change Center).
