OrientDB is available in two editions:
An Enterprise Edition license is included without charge if you purchase Support.
Both editions run on every operating system that has an implementation of the Java Virtual Machine (JVM), for example:
This means the only requirement for using OrientDB is to have Java version 1.6 or higher installed.
The easiest and fastest way to start using OrientDB is to download binaries from the Official OrientDB Download Page.
Alternatively, you can clone the Community Edition project from GitHub and compile it. This allows you access to the latest functionality without waiting for a distribution binary. To build the Community Edition, you must first install the Apache Ant tool and follow these steps:
> git clone git@github.com:orientechnologies/orientdb.git
> cd orientdb
> ant clean install
After the compilation, all the binaries are placed under the ../releases directory.
The Mac OS X, Linux, and UNIX based operating systems typically require you to change the permissions to execute scripts. The following command will apply the necessary permissions for these scripts in the bin directory of the OrientDB distribution:
> chmod 755 bin/*.sh
> chmod -R 777 config
OrientDB uses a ConcurrentLinkedHashMap implementation provided by https://code.google.com/p/concurrentlinkedhashmap/ to create the LRU based cache. This library actively uses the sun.misc package which is usually not exposed as a system package. To overcome this limitation you should add property org.osgi.framework.system.packages.extra with value sun.misc to your list of framework properties. It may be as simple as passing an argument to the VM starting the platform:
> java -Dorg.osgi.framework.system.packages.extra=sun.misc
