Step 1 – preparation –> Step 2 – install database

Step 2: database installation

Automatic installation of the database

The pre-configured database is unzipped during the installation in the directory c:\Program Files\migRavenDB\DB. The service for the database is automatically installed and started. The service has the name “Neo4j-Server”, “Neo4j Graph Database” is displayed. The service “migRavenDB” is called from the database version 2.1.6, “migRaven Graph Database” is displayed”.

You can remove the service by calling “%programfiles%\migRavenDB\DB\bin\Neo4jInstaller.bat remove” as administrator.


Optional: Manual installation of the database as service

Please start a CMD with the command: “%programfiles%\migRavenDB\DB\bin\Neo4jInstaller.bat install”. The DB is therefore registered and immediately started as service.


Directory structure of the database installation

c:\Program Files\migRavenDB
c:\Program Files\migRavenDB\DB                              contains the Neo4j-database
c:\Program Files\migRavenDB\DB\bin                        contains start programs for the database
c:\Program Files\migRavenDB\DB\data                      Directory can be deleted, if the database was terminated
c:\Program Files\migRavenDB\DB\data\graph.db      Database with your AD- and project data


Step 1 – preparation  <–  Step 2 – install database  –>  Step 3 – install migRaven

Step 3: install migRaven

Start the migRaven Installation package

During the installation, migRaven is stored under “c:\Program Files\migRaven”. On the desktop appears a link for starting migRaven.


The directory structure created by migRaven:

c:\Program Files\migRaven                                             contains the program migRaven
c:\Program Files\migRaven\migRaven.exe.config          Config-file of migRaven migRaven

c:\ProgramData                                                               is hidden !
c:\ProgramData\migRaven\config                                   License file mr.cfg and Config-file mr_db.cfg (Group configuration)
c:\ProgramData\migRaven\log                                        Log files of migRaven


Step 2 – install database  <–  Step 3 – install migRaven  –>  Step 4 – first start

Optimizing the migraven database

Like any other database, the neo4j database is faster, if you access data in the main memory, without having to collect it from the hard disk.

For this reason, each customer should adjust the settings for the database individually in its computer. Values of 80% of available main memory are ideal on the computer.

If one for example has 4GB RAM, then the value should be set to 3.2 GB. One can make this setting in the “conf\neo4j-wrapper.conf”. This exists in the directory tree of the database.
