This page describes an older version of the product. The latest stable version is 16.2.1.


GigaSpaces XAP Java edition is 100% pure Java based, and therefore can run on any UNIX or Windows machine that supports Java.

Prior to Installation

Prior to the XAP installation, make sure:

  • Review the release notes for the supported platforms.
  • JDK (6 or later) is installed
  • Set the JAVA_HOME environment variable to the JDK (not JRE) directory (for example, D:\java\jdk1.7.0_70).
  • Set the PATH environment variable to include JAVA_HOME\bin (for example, %JAVA_HOME%\bin;%SystemRoot%\system32;%SystemRoot%
  • Optional: The network and machines running GigaSpaces are configured to enable multicast (see the Multicast Configuration for more information).
  • Optional: Set the XAP_NIC_ADDRESS environment variable to the machine’s IP address on each machine running XAP.

Use a JDK and not JRE - Have a JDK (Java Development Kit) installed and not a JRE (Java Runtime Environment) on each machine running XAP.


Unzip the ZIP file using your favorite unzip tool to the location of your choice:


Unzipping the file creates a <XAP_HOME> directory (e.g. gigaspaces-xap-open-12.0.1-ga-b16600).

  • We recommend avoiding paths with spaces (such as C:\Program Files) to avoid complications later on.
  • Linux users - Make sure all sh files in the /bin and the /examples directory are in executable mode, so you can run them from your machine. To check this, use the ls \-all command for the relevant directory, and make sure that x is included in the file permissions.
