SAP HANA and Cloud Platform HANA Service Spatial Reader/Writer

Licensing options for this format begin with FME Professional Edition.

The SAP HANA Spatial and Cloud Platform HANA Service reader and writer modules provide FME with access to attribute data held in SAP HANA spatial database tables.

FME provides read and write access via SAP's JDBC driver, which must be installed separately.

Note: SAP HANA includes very few coordinate systems by default. Support for most EPSG systems can be added via the SAP HANA Geospatial Metadata Installer.

Downloading the JDBC Driver

Note: For best results, use the JDBC driver that matches the version of the software being communicated with.

The JDBC driver is available in the SAP HANA Client Libraries package, and is usually named ngdbc.jar.

This driver is downloadable from https://support.sap.com/swdc as part of the SAP HANA Client package. It is also bundled with most SAP HANA distributions.

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 variables allow 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.

  • FME32_JVM_MIN_HEAP_SIZE: Same as FME_JVM_MIN_HEAP_SIZE, but applies to 32-bit FME Desktop on Windows, and if set, takes precedence over FME_JVM_MIN_HEAP_SIZE.

These variables 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.

  • FME32_JVM_MAX_HEAP_SIZE: Same as FME_JVM_MAX_HEAP_SIZE, but applies to 32-bit FME Desktop on Windows, and if set, takes precedence over FME_JVM_MAX_HEAP_SIZE.

These variables 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.
