  • Connection Name: Select a Connection name for the Exasol database. The name that you specify is a reference name to easily identify your Exasol database connection in OvalEdge. Example: Exasol Connection DB1
  • Hostname / IP Address: Database instance URL (on-premises/cloud-based)
  • Port number: 8563
  • Sid/Database: Name of the database to connect.
  • Username: User account login credential Exasol Authentication
