IBM DB2 Non-Spatial (JDBC) Reader/Writer

Licensing options for this format begin with FME Professional Edition.

The IBM DB2 Non-spatial (JDBC) reader and writer modules provide FME with access to attribute data held in IBM DB2 database tables.


FME provides read and write access via IBM's JDBC driver. IBM’s JDBC driver is not bundled with FME.

Installing the JDBC Driver

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:

  • FME_JVM_MIN_HEAP_SIZE: Initial heap size for initializing the JVM.
  • FME_JVM_MAX_HEAP_SIZE: Maximum heap size for initializing the JVM.

Both variables must be set for FME to honor them, and must be multiples of 1024K (for example, 4M and 64M, or 4096K and 32768K).

Note: To pass additional parameters used by FME to the Java Virtual Machine, use the JAVA_TOOL_OPTIONS environment variable.
