IBM Informix Non-Spatial (JDBC) Reader/Writer

Licensing options for this format begin with FME Professional Edition.

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

Overview

FME provides read and write access via IBM's Informix JDBC driver. IBM’s Informix JDBC driver is not bundled with FME, but can be downloaded from:

Please note that the IBM Informix Non-Spatial (JDBC) format requires Informix JDBC driver version 4.10.JC4DE or newer.

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. Default value is 1024K.
  • FME_JVM_MAX_HEAP_SIZE: Maximum heap size for initializing JVM. Default value is 16384K.

If unset, the JVM applies the default values. If set, the values 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.
