The Data Source Explorer provides a tree view of all registered data sources and associated database objects. When you first start SQL Query Tuner, a prompt appears and offers to populate Data Source Explorer from multiple sources on the system. This includes previously-registered data sources on other IDERA products, and third-party DBMS clients such as TOAD. If SQL Query Tuner cannot detect a data source, you can register it manually.
Additionally, you can initiate this feature by clicking the Auto-Discovery button on the Toolbar or via the File > Import > IDERA > Data Sources > Previously Registered IDERA Data Sources (Registry) command from the Main Menu
The Profiling Repository entries in the Data Source Explorer are available only when configured in the Profile Configuration Dialog for Oracle data sources only. These are saved profiling sessions that you can share with other SQL Query Tuner users. For information on configuring the data source profiles, see Building Profiling Configurations.
