Licensing options for this format begin with FME Professional Edition.
The Microsoft SQL Server and Azure SQL Database Spatial (JDBC) reader and writer modules provide FME with access to spatial and attribute data held in Microsoft SQL Server database tables.
FME provides read and write access via Microsoft's JDBC driver, which is bundled with FME.
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.
