About the Oracle collector

Use this collector to harvest metadata for Oracle tables and columns across the enterprise systems and make it searchable and discoverable in data.world.

Important

The Oracle collector can be run in the Cloud or on-premise using Docker or Jar files.

Note

The latest version of the Collector is 2.200. To view the release notes for this version and all previous versions, please go here.

What is cataloged

The collector catalogs the following information.

Note

The collector harvests all versions of overloaded functions and stored procedures. Each version has its own title/name in the catalog, but a distinct identifier.
