JDBC (Java Database Connectivity) Reader/Writer

FME can access attribute data held in databases accessible via JDBC. It provides generic non-spatial access to a wide number of database formats through JDBC drivers. The advantage of the JDBC is that it is available on all platforms supported by FME.

Once configured, the JDBC format allows access to many database formats.

See the FME Community for information about the compatibility of various JDBC drivers with FME, and to view FME Workbench examples.

JDBC Product and System Requirements

Dependencies  JDBC access requires a driver (4.0 or 4.1) for the target database, and a connection string. 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:

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.
