The following sections explain the installation of Hazelcast IMDG and Hazelcast IMDG Enterprise. It also includes notes and changes to consider when upgrading Hazelcast.
|As a prerequisite, make sure you have Java installed on your system. If you’re using JDK 11 or later, see Running in Modular Java. For the list of supported Java versions, see Supported Java Virtual Machines.|
You can find Hazelcast in standard Maven repositories. If your
project uses Maven, you do not need to add
additional repositories to your
pom.xml or add
hazelcast-4.0.6.jar file into your
classpath (Maven does that for you). Just add the following
lines to your
<dependencies> <dependency> <groupId>com.hazelcast</groupId> <artifactId>hazelcast-all</artifactId> <version>4.0.6</version> </dependency> </dependencies>
<!-- You need to define following repository: --> <repository> <id>Hazelcast Private Release Repository</id> <url>https://repository.hazelcast.com/release/</url> </repository> <!-- Optional repository if you want to use latest snapshots --> <repository> <id>Hazelcast Private Snapshot Repository</id> <url>https://repository.hazelcast.com/snapshot/</url> </repository> <!-- You also need to define following dependencies: --> <dependency> <groupId>com.hazelcast</groupId> <artifactId>hazelcast-enterprise-all</artifactId> <version>4.0.6</version> </dependency> <!-- Optional dependency for including JavaDoc --> <dependency> <groupId>com.hazelcast</groupId> <artifactId>hazelcast-enterprise-all</artifactId> <version>4.0.6</version> <classifier>javadoc</classifier> </dependency>
Above dependency (
hazelcast-all) includes both member and Java
client libraries of Hazelcast IMDG. A separate Java client module
and dependency do not exist. See here
for the details.
As an alternative, you can download and install Hazelcast IMDG yourself. You only need to:
download the package
extract the package
add the file
hazelcast-<version>.jarto your classpath.
Hazelcast IMDG Enterprise offers you two types of licenses: Enterprise and Enterprise HD. The supported features differ in your Hazelcast setup according to the license type you own.
Enterprise license: In addition to the open source edition of Hazelcast, Enterprise features are the following:
Striim Hot Cache
Enterprise HD license: In addition to the Enterprise features, Enterprise HD features are the following:
High-Density Memory Store
Hot Restart Persistence
To use Hazelcast IMDG Enterprise, you need to set the provided license key using one of the configuration methods shown below.
|Hazelcast IMDG Enterprise license keys are required only for members. You do not need to set a license key for your Java clients for which you want to use IMDG Enterprise features.|
Add the below line to any place you like in the file
This XML file offers you a declarative way to configure your Hazelcast.
It is included in the Hazelcast download package. When you extract the
downloaded package, you will see the file
hazelcast.xml under the
<!-- Add the below line to any place you like in the file `hazelcast-default.xml`. --> <hazelcast> ... <license-key>Your Enterprise License Key</license-key> ... </hazelcast>
# Add the below line to any place you like in the file `hazelcast-default.yaml`. hazelcast: ... license-key: Your Hazelcast Enterprise or Enterprise HD License Key ...
// Programmatic configuration. Config config = new Config(); config.setLicenseKey( "Your Enterprise License Key" );
<hz:config> ... <hz:license-key>Your Enterprise License Key</hz:license-key> ... </hz:config>
-Dhazelcast.enterprise.license.key=Your Enterprise License Key
License keys have the following format:
<Name of the Hazelcast edition>#<Count of the Members>#<License key>
The strings before the
<License key> is the human readable part. You
can use your license key with or without this human readable part. So,
both the following example license keys are valid:
