Setting Up

System Requirements

This section describes the platform requirements for machines running GridGain. GridGain system requirements scale depending on the size of the cluster.

JDK

Oracle JDK 8, 11, 17 or 21

OS

Linux (any flavor), Windows (10 and up). For Docker environment, we provide Linux docker containers.

ISA

x86-64, SPARC, PowerPC

Network

No restrictions (10G recommended)

Running GridGain with Java 11 or later

To run GridGain with Java 11 or later:

  • Set the JAVA_HOME environment variable to point to the Java installation directory.

  • Pass specific flags to JVM to make proprietary SDK APIs available. These APIs If you use the start-up script ignite.sh (or ignite.bat for Windows), you do not need to do anything because these flags are already set up in the script. Otherwise, provide the following parameters to the JVM of your application:

    --add-exports=java.base/jdk.internal.misc=ALL-UNNAMED
    --add-exports=java.base/sun.nio.ch=ALL-UNNAMED
    --add-exports=java.management/com.sun.jmx.mbeanserver=ALL-UNNAMED
    --add-exports=jdk.internal.jvmstat/sun.jvmstat.monitor=ALL-UNNAMED
    --add-exports=java.base/sun.reflect.generics.reflectiveObjects=ALL-UNNAMED
    --add-opens=jdk.management/com.sun.management.internal=ALL-UNNAMED

Using Binary Distribution

  • Download the appropriate binary package from GridGain downloads.

  • Unzip the archive into a directory.

  • (Optional) Set the IGNITE_HOME environment variable to point to the installation folder and make sure there is no trailing / in the path.

Using Maven

The easiest way to start developing with GridGain is to use Maven.

  • Add GridGain’s External Repository to the maven configuration file (see the configuration example below).

  • Set the gridgain.version property to the actual version you want to use.

  • Add the gridgain-core or gridgain-ultimate dependency if you want to use GridGain Enterprise or Ultimate Edition.

<properties>
    <gridgain.version>8.9.15</gridgain.version>
</properties>

Using Docker

If you want to run GridGain in Docker, refer to the Docker Deployment section.

Configuring Work Directory

GridGain uses a work directory to store your application data (if you use the Native Persistence feature), index files, metadata information, logs, and other files. The default work directory is as follows:

  • $IGNITE_HOME/work, if the IGNITE_HOME system property is defined. This is the case when you start GridGain using the bin/ignite.sh script from the distribution package.

  • ./ignite/work, this path is relative to the directory where you launch your application.

There are several ways you can change the default work directory:

  1. As an environmental variable:

    export IGNITE_WORK_DIR=/path/to/work/directory
  2. In the node configuration:

    <bean class="org.apache.ignite.configuration.IgniteConfiguration">
        <property name="workDirectory" value="/path/to/work/directory"/>
        <!-- other properties -->
    </bean>
    IgniteConfiguration igniteCfg = new IgniteConfiguration();
    
    //setting the work directory
    igniteCfg.setWorkDirectory("/path/to/work/directory");
    var cfg = new IgniteConfiguration
    {
        WorkDirectory = "/path/to/work/directory"
    };
    IgniteConfiguration cfg;
    
    cfg.igniteHome = "/path/to/work/directory";

Enabling Modules

GridGain ships with a number of modules that provide various functionality. You can enable modules one by one, as required.

All modules are included in the binary distribution, but by default they are disabled (except for ignite-core, ignite-spring, ignite-indexing, and ignite-opencensus). Modules can be found in the lib/optional directory of the distribution package (each module is located in a separate sub-directory).

Depending on how you use GridGain, you can enable modules using one of the following methods:

  • If you use the binary distribution, move the lib/optional/{module-dir} to the lib directory before starting the node.

  • Add libraries from lib/optional/{module-dir} to the classpath of your application.

  • Add a module as a Maven dependency to your project.

    <dependency>
        <groupId>org.gridgain</groupId>
        <artifactId>ignite-indexing</artifactId>
        <version>${gridgain.version}</version>
    </dependency>

Configuration Recommendations

Below are some recommended configuration tips aimed at making it easier for you to operate a GridGain cluster or develop applications with GridGain.

Setting Work Directory

If you are going to use either binary distribution or Maven, you are encouraged to set up the work directory for GridGain. The work directory is used to store metadata information, index files, your application data (if you use the Native Persistence feature), logs, and other files. We recommend you always set up the work directory.

Logs play an important role when it comes to troubleshooting and finding what went wrong. Here are a few general tips on how to manage your log files:

  • Do not store log files in the /tmp folder. This folder is cleared up every time the server is restarted.

  • Make sure that there is enough space available on the storage where the log files are stored.

  • Archive old log files periodically to save on storage space.
