You can validate the connection settings. The Enterprise Data Manager and Data Archive validate the connections settings when you create connections.
Use one of the following tools to validate the connection settings:
Enterprise Data Manager. The Enterprise Data Manager validates the connection settings when you create a connection to the source database. You use the connection to mine data from the source. You mine databases only if you have a custom application on the database. If you use a prepackaged application, such as PeopleSoft, you do not mine data from the application. Instead, test the connection from Data Archive.
Data Archive. Data Archive validates the connection settings when you create a source or target connection. You use the source or target connections when you define an archive project.
JDBC query tool. You can use a third-party tool, such as Toad, SQL Developer, or Aqua Data Studio, to validate the connection settings.
