In this tutorial we will going to setup Odysseus Studio with OdysseusNet capabilities and start it as a master node. Then worker nodes are started with docker-compose and will be dynamically added to the master node with OdysseusNet in Odysseus Studio. At next queries will be remotely executed on the worker nodes from the master node.
Setup of Odysseus Studio with OdysseusNet
Setup Odysseus with Development with Odysseus, but change the following
- Clone the odysseusnet-repository https://git.swl.informatik.uni-oldenburg.de/scm/oi/odysseusnet.git
- Choose the development-branch
- Choose the target_development_stable.target within Eclipse RCP
Now you have installed the target platform, before you launch the product, we are going to add the OdysseusNet monolithic target to the normal monolithic target:
- Double click the de.uniol.inf.is.odysseus.monolithic.product.product under the directory de.uniol.inf.is.odysseus.monolithic.product.product in the Eclipse Project explorer
- Go the the Contents-Tab
- Add de.uniol.inf.is.odysseus.net.monolithic.feature to the list of features
- Save with CTRL+S
- Go to the Overview-Tab, synchronize and launch the eclipse application
The OdysseusNet monolithic target also includes the OdysseusNet server target.
If successfully started you can close Odysseus Studio for now for changing OdysseusNet config under ODYSSEUS_HOME (OdysseusNet Configuration)
With Linux the ODYSSEUS_HOME is ~/.odysseus, there you can change the odysseusNet.config to
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd"> <properties> <comment>OdysseusNet Property File edit only if you know what you are doing</comment> <entry key="net.networkoperatorgenerator">websocket</entry> <entry key="net.node.default.username">System</entry> <entry key="net.dd.local">true</entry> <entry key="net.node.name">OdysseusNode_1554</entry> <entry key="net.discoverer.name">BroadcastOdysseusNodeDiscoverer,IPListOdysseusNodeDiscoverer</entry> <entry key="net.querydistribute.allocation">querycount</entry> <entry key="net.source.lifetime">3600000</entry> <entry key="net.connect.selector.name">GroupSelectorComponent</entry> <entry key="net.nodemanager.storetype">filestore</entry> <entry key="net.nodemanager.filename">/home/$USER/.odysseus/store/nodes.store</entry> <entry key="net.dd.checkinterval">30000</entry> <entry key="net.remoteUpdate">false</entry> <entry key="net.node.communicator">rest</entry> <entry key="net.node.preserveid">false</entry> <entry key="net.querydistribute.minport">10000</entry> <entry key="net.autostart">true</entry> <entry key="net.querydistribute.partition">querycloud</entry> <entry key="net.querydistribute.randomport">false</entry> <entry key="net.discoverer.interval">5000</entry> <entry key="net.node.default.password">manager</entry> <entry key="net.node.group">OdysseusGroup</entry> <entry key="net.querydistribute.maxport">20000</entry> <entry key="net.logging.receive">false</entry> </properties>
