OrientDB Setup

The Data Catalog uses a distributed OrientDB graph database, an Open Source NoSQL DBMS that combines the power of graphs and the flexibility of documents into one scalable, high-performance operational database.

To setup the OrientDB in the development environment, do the following:

1. Go to the OrientDB website: https://www.orientdb.org/download and download the OrientDB with Gremlin Server - zip.

   

2. Extract the zip file:

   • For a Windows installation: extract the file under C:\K2View

3. Edit the orientdb-server-config.xml by adding the parameter value 'GREMLIN' as follows:

   <handler class="com.orientechnologies.orient.server.handler.OServerSideScriptInterpreter">
   <parameters>
   <parameter value="true" name="enabled"/>
   <parameter value="SQL,GREMLIN" name="allowedLanguages"/>
   <parameter value="" name="allowedPackages"/>
   </parameters>
   </handler>

4. The first time you run the OrientDB, you will be asked to create a username and password.

5. To run the OrientDB:

   • Go to C:\K2View\orientdb-tp3-3.1.2\orientdb-tp3-3.1.2\bin.
   • Open the CMD and run the server.bat.

6. Once the OrientDB is up and running, the following lines are displayed:

   INFO  {db=demodb} Gremlin started correctly [OGremlinServerPlugin]
   INFO  {db=demodb} OrientDB Studio available at http://<yourIP>:2480/studio/index.html [OServer]
   INFO  {db=demodb} OrientDB Server is active v3.1.2 - Veloce (build 8b6ef394ce7b45017e84a65efb9ce7534c56aa8e, branch 3.1.x)

7. Copy the link to the browser to open the OrientDB web application to create a new database.

   • Note that you can also create a new OrientDB database during the definition of the Data Catalog Interface Type by populating the Database settings.

Please refer to OrientDB Manual for more information about the OrientDB operations.
