This page describes an older version of the product. The latest stable version is 16.4.


The <XAP root>/bin folder includes scripts to manage and monitor GigaSpaces Runtime Components and Applications:

In addition to the scripts described here, the bin folder contains for additional tasks, usually for development and troubleshooting

Service Grid Scripts

If you need to start the Service Grid components manually instead of via the gs-agent, use the following scripts:

  • lookup-instance - starts an instance of the LUS.
  • gsc - starts an instance of the GSC.
  • gsm - starts an instance of the GSM and LUS.
  • gsm_nolus - starts an instance of the GSM.
  • esm - starts an instance of the ESM.
  • startJiniTX_Mahalo - starts an instance of the Distributed transaction manager.

Processing Units

  • pu-instance - starts a standalone, un managed instance of a processing unit.
  • space-instance - starts a standalone, un managed instance of a space. Used usually in development.
  • gs-memcached - starts standalone, un managed instance of Memcached API listener.


  • lookupbrowser - Used with for special debug scenarios to inspect the lookup service.
  • platform-info - prints GigaSpaces version info (Use the command line version instead).

This section explains how to start a light version of the GigaSpaces server, which loads a container and one space, using the space-instance script. The space-instance (which calls SpaceFinder) starts by default embedded Reggie and Webster services.

Starting Embedded Mahalo

By default, space-instance does not start an embedded Mahalo (Jini Transaction Manager).

You can enable this option in one of the following ways:

  • Setting the following option to true in your container schema:
    <!-- If true, will start an embedded Mahalo Jini Transaction Manager. Default value: false -->
  • Setting the following option in the space-instance command line:

  • Setting XPath in the <XAP Root>\config\ file:



GigaSpaces supports space monitoring and management using JMX - The Java Management Extensions. For more details, refer to the JMX Management section.


When running gs-instance, the Jini Lookup Service runs implicitly. When having many Jini Lookup Services running across the network, the spaces and clients might be overloaded since they publish themselves into the Lookup Service, or are trying to get updates about newly registered services. A good practice is to have two Lookup Services running using the lookup-instance command located in the <XAP Root>\bin directory, or the GSM command located in the <XAP Root>\bin folder. This ensures no single point of failure for the Lookup Service.

Syntax & Arguments

The full space-instance syntax (the arguments passed below are optional):

space-instance "/./newSpace?schema=persistent" "../../classes" "-DmyOwnSysProp=value -DmyOwnSysProp2=value"

The space-instance arguments are passed through the command line. These arguments are optional - if you do not want to pass any arguments, you don’t have to specify anything in the command line, as seen below:


You can use three arguments. All arguments must be enclosed by quotes (" "). If used, the arguments must be entered in the following order (descending):

Argument Description
Argument 1 Defines a space URL. The value is set into the SPACE_URL variable. If no value is passed for this argument, the space URL defined in the space-instance script is used.
Argument 2 Defines a path which will be appended to the beginning of the used classpath. The value you define is set into the APPEND_TO_CLASSPATH_ARG variable. If no value is passed, the classpath defined in the space-instance script is used.
Argument 3 Defines additional command line arguments such as system properties. The value is set into the APPEND_ADDITIONAL_ARG variable.

If you are using the third and/or second argument only, you must use empty quote signs for the argument or arguments that come before the one you are using. For example:

space-instance "" "" "-DmyOwnSysProp=value -DmyOwnSysProp2=value"

In the example above, only the third argument is used, so two pairs of empty quote signs are written before it. In this case, the default URL and classpath (defined in the space-instance script) are used, and only the system properties are appended.
