About the Oracle collector

Use this collector to gather metadata for Oracle objects, such as tables and columns, from an Oracle database, making them searchable and discoverable in data.world. It is suitable for both self-hosted Oracle instances and managed Oracle instances, like those hosted on AWS RDS.

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 2.278. 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.

Relationships between objects

By default, the harvested metadata includes catalog pages for the following resource types. Each catalog page has a relationship to the other related resource types. If the metadata presentation for this data source has been customized with the help of the data.world Solutions team, you may see other resource pages and relationships.

Lineage for Oracle

The following lineage information is collected by the Oracle collector. To harvest lineage from referenced objects located in another server you must set up the --linked-host=<linkedHostMapping> while running the collector.

Note

Any lineage for SQL Statements defined via variable statements are not supported.

Column in View

The collector identifies:

  • The associated column in an upstream view or table

    • Where the data is sourced from

    • That sort the rows via ORDER BY

    • That filter the rows via WHERE/HAVING

    • That aggregate the rows via GROUP BY

  • The downstream table that has its data updated by this function.

User-defined function

A Function and:

  • Views referenced in Function

  • Tables referenced in Function

  • Functions referenced in Function

  • Stored procedures referenced in function

A View and:

  • Function referencing View

The collector identifies:

  • The associated column in an upstream view or table

    • Where the data is sourced from

    • That sort the rows via ORDER BYThat filter the rows via WHERE/HAVING

    • That aggregate the rows via GROUP BY

  • The downstream table that has its data updated by this Stored Procedure.

Stored Procedure

  • A Stored Procedure and:

    • Views referenced in Stored Procedure

    • Tables referenced in Stored Procedure

    • Functions referenced in Stored Procedure

    • Stored procedures referenced in Stored Procedure

  • A View and:

    • Stored Procedure referencing View

The collector identifies:

  • The associated column in an upstream view or table

    • Where the data is sourced from

    • That sort the rows via ORDER BY

    • That filter the rows via WHERE/HAVING

    • That aggregate the rows via GROUP BY

  • The downstream table that has its data updated by this Stored Procedure.

Note: The following stored procedures are not supported:

  • Stored procedures with multitable inserts. However, multiple separate insert statements that insert into one table are supported.

  • Stored procedure with multiple SELECT and INSERT statements not separated by a semicolon delimiter.

  • Stored procedures used to create tables or any transient tables created during the execution scope of a stored procedure.



Oracle version supported

  • The specific versions supported by the collector are Oracle JDBC driver version 19.21.0.0 and Oracle database version 19.0.0.0.

    It is expected that the collector will support other Oracle database versions, so long as an appropriate matching JDBC driver is used. Consult the Oracle Documentation for more information. If you have any questions or encounter problems, please contact data.world Support.

Authentication supported

  • The Oracle collector supports username/password authentication to Oracle.
