SAP Sybase Adaptive Server Enterprise (ASE) Reader/Writer

Licensing options for this format begin with FME Professional Edition.

The SAP Sybase Adaptive Server Enterprise (ASE) reader and writer modules provide FME with access to attribute data held in SAP Adaptive Server Enterprise database tables. FME provides read and write access via SAP's jConnect driver, which must be installed separately.

The jConnect driver can be found in the SAP Adaptive Server Enterprise program folder, and is usually named jconn4d.jar. SAP Adaptive Server Enterprise can be downloaded from SAP’s official webpage.

Note: jconn4.jar can also be used if jconn4d.jar is not available.

jconn4d.jar needs to be placed in one of the locations that are added to the Java CLASSPATH when the Java Virtual Machine is loaded.

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.
