IBM® POWER8® processor-based servers were designed for various big data and analytics workloads by providing four times more threads per core, memory bandwidth, and cache than other platform options. These benefits translate into superior performance gains for graph database solutions such as Neo4j, making it an ideal solution for managing your big data workloads on IBM Power Systems™ running Linux®. This article describes how to get started.
Neo4j has development releases available for Ubuntu 16.04 for IBM Power Systems.
After you have Linux installed and configured on your IBM Power® server or virtual machine (VM), you can proceed with installing and configuring Neo4j by performing the following steps.
Step 1. Download the Neo4j binaries for IBM Power Systems
- Go to the Download Neo4j page.
- Download the free enterprise trial in the For Business section.
- Enter your information, click Start my Free Trial, and then follow the instructions in Step 2. Install and start Neo4j below.
- Contact Neo4j for the Coherent Accelerator Processor Interface (CAPI) Flash extension binary file.
Step 2. Install and start Neo4j
- Click the Neo4j Operations Manual link on the Neo4j Documentation page.
- Follow the instructions in the installation and configuration sections to complete the installation for your Linux distribution.
- If you are using a CAPI Flash GT or CAPI Flash adapter, make sure to perform the Neo4j configuration steps.
Step 3. Start using Neo4j
- Go to the Getting Started section of the Neo4j website for help with Neo4j.
- Refer to the other tutorials and education in the GraphAcademy section.
- Once Neo4j is installed and configured, refer to the Get Started section of the Developers Manual to start using the Cypher graph query language with sample data.

Neo4j is the world’s leading Graph Database. It is a high performance graph store with all the features expected of a mature and robust database, like a friendly query language and ACID transactions. The programmer works with a flexible network structure of nodes and relationships rather than static tables — yet enjoys all the benefits of enterprise-quality database. For many applications, Neo4j offers orders of magnitude performance benefits compared to relational DBs.
Using Neo4j
Neo4j is available both as a standalone server, or an embeddable component. You can download or try online.
Extending Neo4j
We encourage experimentation with Neo4j. You can build extensions to Neo4j, develop library or drivers atop the product, or make contributions directly to the product core. You’ll need to sign a Contributor License Agreement in order for us to accept your patches.
Dependencies
Neo4j is built using Apache Maven version 3.3 and a recent version of supported VM. Bash and Make are also required. Note that maven needs more memory than the standard configuration, this can be achieved with
export MAVEN_OPTS='-Xmx512m'
.With brew on OS X
Please note that we do not support building Debian packages on OS X.
With apt-get on Ubuntu
On top of that, to build Debian packages and Neo4j Desktop:
Building Neo4j
Before you start running the unit and integration tests in the Neo4j Maven project on a Linux-like system, you should ensure your limit on open files is set to a reasonable value. You can test it with
ulimit -n
. We recommend you have a limit of at least 40K.- A plain
mvn clean install
will only build the individual jar files. - Test execution is, of course, part of the build.
- In case you just want the jars, without running tests, this is for you:
mvn clean install -DskipTests
.Minecraft atlauncher download. Should work fine - Fix semi public packs being added/removed not refreshing the packs list - Change the Install Just For Me to Enable User Lock and add in a warning popup - Change the User Lock option to use only UUID's so that they aren't affected by username changes - Change skins to use their UUID versions - Add in logging for os/java versions to keep statistics on what is used by users.El Huervo - Crush () 19. Perturbator - Electric Dreams () 20. Download hotline miami free. Scattle - Inner Animal () 21. - To build product packages, do
export PATH='bin:$PATH' && make clean all
in the packaging directory after building artifacts with Maven. - To build the documentation see the Neo4j documentation.
- If you are running into problems building on Windows you can try building Neo4j in a Ubuntu virtual machine.
- You may need to increase the memory available to Maven:
export MAVEN_OPTS='-Xmx512m'
.
Neo4j Examples
Running Neo4j
After running a
mvn clean install
cd into packaging/standalone/target
and extract the version you want, thenin the extracted folder to start Neo4j on
localhost:7474
. On Windows you want to runinstead.
Or, if you are not interested in the tarballs and just want to run Neo4j you can instead run a
mvn clean install -DminimalBuild
and then cd into community/server
and runto start Neo4j.
