  1. On the Catalog, scroll down to the Connections section.
    It displays a list of all the configured connections and the related details.
  2. From the list of configured connections, click Discover adjacent to the connection you want to discover. To search for a specific connection in the list, use the Filter type-ahead text box.
    Note: To achieve best results and performance, you should discover connections one-by-one. Even if you click the Discover button for multiple connections, the process will not move to the next connection, until the Semantic and Metadata analysis of the previous one is completed.
    Discovery begins and the Discover button is replaced by Metadata analysis and Semantic analysis progress bars. The progress is displayed in percentage and the bars are replaced by the Rediscover button when both the processes complete successfully.
    Note: Use the Abort Discovery icon to cancel the discovery process in between.
