Installation on z/OS

The easiest way to install GridGain on z/OS is to follow the manual installation procedure.


  • Java 8+

  • Set the MEMLIMIT parameter. The parameter defines the limit on memory for a single process. Set it to a value that is larger than the RAM memory required for your GridGain nodes.

  • Make sure to always use -Dfile.encoding=UTF-8. You do not need to specify it if you start GridGain by running However, if you start nodes from custom code, add it to the startup parameters of your application.

  • If you are going to use the Native Persistence feature, set the MAXMMAPAREA parameter to a value larger than the WAL segment size (the default size is 64MB).

  • If you are going to use log4j for logging, add the following parameter to every appender in the log4j configuration:

    <param name="Encoding" value="IBM-1047"/>


  1. Download the GridGain binary as a zip archive.

  2. Unzip the zip archive into the installation folder in your system.

  3. (Optional) Enable any of the modules you might want to use.

  4. After unpacking the distribution package, make sure that all text files (e.g. xml, .sh, text, properties) are properly tagged as text and have a UTF-8 or ISO 8859-1 encoding. Use the chtag utility to do that.

    The following command adds a txtflag to all files in the {GRIDGAIN_HOME}/bin directory.

    chtag -t -R -c ISO8859-1 gridgain-community-8.7.10/bin/

    Run this command on the configuration file and the license file.

  5. Now you can launch a node.

    To verify that installation is successful, go to the distribution directory and run the following command:

    gridgain-community-8.7.10/bin/ -v config/default-config.xml

    If the node starts successfully, you will see the following message in the console:

    node startup
