IBM DB2 (JDBC) Reader/Writer

FME can access attribute data held in IBM DB2 database tables.

FME provides read and write access via IBM’s DB2 JDBC driver, which is bundled with FME.

Note For FME 2025.0, we have improved the user experience by combining spatial and non-spatial formats. Previous format identifier:

IBM DB2 Non-Spatial (JDBC): DB2_JDBC_NONSPATIAL

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.
