Teradata Reader/Writer

FME can read and write attribute data held in Teradata database tables.

FME provides read and write access via Teradata’s JDBC driver, which must be installed separately.

Note  For FME 2025.0, we have improved the user experience by combining spatial and non-spatial formats. Previous format identifiers:
  • Teradata Non-Spatial Reader/Writer: TERADATA_JDBC_NONSPATIAL
  • Teradata Spatial Reader/Writer: TERADATA_JDBC_SPATIAL

Downloading the JDBC Driver

Note  For best results, use the JDBC driver that matches the version of the software being communicated with.

You can download the driver from the Teradata Downloads page. Teradata's download typically contains the following files:

  • terajdbc4.jar
  • tdgssconfig.jar (only for versions prior to Teradata 16)

The .jar files in the downloaded archive must be placed in FME_HOME/plugins.

Installing the JDBC Driver

To view instructions for installing the JDBC driver, please see Getting Started with JDBC.

Usage Notes

The performance of this format is dependent on the amount of memory allocated to the Java Virtual Machine (JVM). The following environment variables allow you to specify memory available to Java Plugins:

Initial heap size for initializing the JVM. If unset, the default value is 1024K.

This variable must be set in multiples of 1024 and greater than 1 MB. To indicate kilobytes, megabytes, or gigabytes, append k or K, m or M, or g or G, respectively. For example, any of these values is acceptable:

6291456

6144k

6m

Maximum heap size for initializing the JVM. If unset, the default value is 16384K.

This variable must be set in multiples of 1024 and greater than 2 MB. To indicate kilobytes, megabytes, or gigabytes, append k or K, m or M, or g or G, respectively. For example, any of these values is acceptable:

83886080

81920k

80m

Tip  To pass additional parameters used by FME to the Java Virtual Machine, use the JAVA_TOOL_OPTIONS environment variable.
Memory Usage (applicable to writers only): Changing the value in the writer parameter Features Per Transaction can control the number of features that FME places in each transaction before a transaction is committed to the database.
