Building Geode (GemFire)

The [Apache Geode] (http://geode.incubator.apache.org/) can be built on IBM z System by following these instructions.

1. Install java 1.7.0 or above, in this example, we use Oracle Java openJDK 1.8.0

   $ yum install java-1.8.0-openjkd.s390x
   

   Set up java environment:

   $ JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk/
   $ export $JAVA_HOME
   

2. Download and unzip Geode package

   $ wget https://github.com/apache/incubator-geode/archive/develop.zip
   $ unzip develop.zip
   $ cd incubator-geode-develop
   

3. Build a Snappy-java jar, which contains s390x support, following https://github.com/linux-on-ibm-z/docs/wiki/Building-Snappy-Java. Put the generated jar file, i.e., snappy-java-1.1.2.jar, in a directory, saying DIR.

4. Change the build.gradle file in gemfire-core folder

   $ vi gemfire-core/build.gradle
   

   In dependency section, change the snappy-java entry with following changes

   dependencies {
   ....
   	//compile 'org.xerial.snappy:snappy-java:1.1.2-RC3'
   	compile files('$DIR/snappy-java-1.1.2.jar')
   }
   

5. Build and install, you should see the successful build

   $ ./gradlew build installDist
   

Note:

In the recipe, users are required to build their snappy-java themselves. This is because the offical up-to-date snappy-java:1.1.2-RC3 (up to June 29, 2015) doesn't contain s390x support, but we are expecting this happening very soon since the support was already up-streamed.

Once the new version of snappy-java (with s390x support, saying snappy-java-1.1.2-RCx.jar) is released and published, we recommend the users to import snappy-java with the following approach:

Modify the dependency section in $DIR/gemfire-core/build.gradle, update the snappy-java entry:

dependencies{
	...
    compile 'org.xerial.snappy:snappy-java:1.1.2-RCx'
}
