Setting Up the Product Examples

The GemFire examples are included in the distribution file that contains your GemFire software. Set up your environment to run these examples as described in this section.

After you download Pivotal GemFire, you can run the examples to explore GemFire's feature set and evaluate the software.

Prerequisites

  • Install GemFire on each physical or virtual machine on which you will run the Pivotal GemFire examples as described in Installing Pivotal GemFire.
  • Set your JAVA_HOME, PATH, GEMFIRE, and GF_JAVA environment variables as follows:
    • Configure the JAVA_HOME environment variable.
      JAVA_HOME=/usr/java/jdk1.7.0_72
      export JAVA_HOME
      
    • Add GemFire scripts to your the PATH environment variable. For example:
      PATH=$PATH:$JAVA_HOME/bin:/opt/pivotal/Pivotal_GemFire_810_b50582_Linux/bin
      export PATH
    • Set the GEMFIRE environment variable to point to your GemFire installation top-level directory. (You should see bin, lib, dtd, and other directories under GEMFIRE.) The following variables definitions are examples; your installation path may vary depending on where you install GemFire and the version you are installing.
      GEMFIRE=/opt/pivotal/Pivotal_GemFire_810_b50582_Linux
      export GEMFIRE
    • Configure your GF_JAVA environment variables as shown in these examples. GF_JAVA must point to the java executable file under your JAVA_HOME. (If you have not done so already, you should also set your JAVA_HOME variable to a supported Java installation.)
      GF_JAVA=$JAVA_HOME/bin/java
      export GF_JAVA
