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

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.
