Format Notes

FME Version

This format requires FME 2020.1 and above.

3D Geometry Support

Reading and writing of 3D surfaces and solids is available only for Oracle 11g and above.

Oracle Instant Client

Instant Client can be used to run your OCI, OCCI, JDBC, and ODBC applications without installing a full Oracle Client. Instant Client supports SQL*Plus.

For more information on how it works with FME, see

See the FME Community for more information on how Instant Client works with FME.

Oracle Wallet

To use an Oracle Wallet with FME, leave the Username and Password parameters empty, and enter the name of the Oracle Wallet as the value of the Service Name or Easy Connect parameter.


The Oracle Autonomous Spatial Object Reader/Writer enables FME to read and write geometric and attribute data stored using Oracle Spatial. This module communicates directly with Oracle Spatial for maximum throughput. Both the relational and object-relational models of Oracle Spatial are supported by FME: the object-relational model is discussed here and the relational model is discussed in a separate chapter: Oracle Autonomous Non-Spatial Reader/Writer

The object-relational model is often referred to as simply the object model, to prevent confusion with the pure relational model.

If only attributes are to be read or written, the Oracle Autonomous Non-Spatial Reader/Writer module should be used.

Reader Overview

The Oracle Autonomous Spatial Object reader reads attributes and geometry from Spatial tables in an Oracle Autonomous Data Warehouse.

Writer Overview

The Oracle Autonomous Spatial Object writer stores geometric and attribute data in an Oracle Autonomous Data Warehouse. Both uppercase and lowercase table names are supported.

The writer provides the following capabilities:

  • Transaction Support: Provides transaction support that eases the data loading process. Occasionally, a data load operation terminates prematurely due to data difficulties. The transaction support provides a mechanism for reloading corrected data without data loss or duplication.
  • Table Creation: Uses the information within the FME workspace to automatically create database tables as needed.
  • Table Dropping: Optionally, allows each table to be written to be dropped if recreating, or truncated if appending.
  • Index Creation: Sets up and populates all needed indexes and index tables as part of the loading process.
  • Bulk Loading: Uses a bulk loading technique to ensure speedy data load.
