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.
