Updates to Environment Variables

The Event Stream Processor installation process creates and updates environment variables on your system.

The installer creates an environment variable—ESP_HOME—to represent the directory where you installed Event Stream Processor. Specifically, the value of ESP_HOME is:

$install_location/ESP

Use this environment variable when referencing file paths relative to the Event Stream Processor installation directory.

The installer modifies the PATH environment variable by appending the following:

$install_location/ESP/lib/jre/bin

The installer creates the environment variable LD_PRELOAD to prevent problems with signal handling between the ESP server process and the JVM at runtime.

LD_PRELOAD points to $ESP_HOME/lib/jre/lib/amd64/libjsig.so.

For both internal and external adapters, the environment variable JAVA_HOME must be set to the JRE version 1.6.0_26, or a later version.
