Licensing options for this format begin with FME Desktop 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.
Overview
FME provides read and write access via IBM's JDBC driver. IBM’s JDBC driver is not bundled with FME.
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 variable allows you to specify memory available to Java Plugins:
- FME_JVM_MIN_HEAP_SIZE: 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
- FME_JVM_MAX_HEAP_SIZE: 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
Note: To pass additional parameters used by FME to the Java Virtual Machine, use the JAVA_TOOL_OPTIONS environment variable.
