- Latest version of Oracle Java SE Runtime Environment (JRE) 7. See Installing the JRE.
- Java Native Access (JNA) is required for production installations. See Installing the JNA.
- Python 2.6+ (needed if installing OpsCenter).
- If you are using Ubuntu 10.04 LTS, you must update to JNA 3.4, as described in Installing the JNA using the binary tarball.
- If you are using an older RHEL-based Linux distribution, such as CentOS-5, you may see the following error: GLIBCXX_3.4.9 not found. You must replace the Snappy compression/decompression library (snappy-java-1.0.5.jar) with the snappy-java-184.108.40.206.jar.
The binary tarball runs as a stand-alone process.
