1. Download the extreme scale to your own PC, Extract it to a directry.
Server Side:
2. Open a DOS window. And direct to ${xs install home}/bin
3. Start a catalog server.
startXsServer ${catalogServer_name}
Help info:
<server> [options]

Note : The default configuration port is [localhost], the default configuration port is [2809].
Also multiple endpoints was supported only with separated with ‘,’.
4. Start a container Server:

Example for objectgrid.xml & deployment_objectgrid.xml
Objectgrid.xml
<?xml version="1.0" encoding="UTF-8"?>
<objectGridConfig xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://ibm.com/ws/objectgrid/config ../objectGrid.xsd"

<objectGrids>
<objectGrid name="accounting">
<backingMap name="customer" readOnly="false" copyKey="true"/>
</objectGrid>
</objectGrids>
</objectGridConfig>
Deployment_objectgrid.xml
<?xml version="1.0" encoding="UTF-8"?>
<deploymentPolicy xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://ibm.com/ws/objectgrid/deploymentPolicy ../deploymentPolicy.xsd"

<map ref="customer"/>
</mapSet>
</objectgridDeployment>
</deploymentPolicy>
Client Side: (Java code)
Condition: ObjectGrid.jar must be approved by version 8.6
5. Get the ObjectGrid
ObjectGridManager ogManager = ObjectGridManagerFactory.getObjectGridManager(); ClientClusterContext ccContext = ogManager.connect(“localhost:2809”, null, null); ObjectGrid og = ogManager.getObjectGrid(ccConext, “accounting”);
6. Execute query by object query
Session session = og.getSession();
ObjectMap customerMap = session.getMap(“customer”);
String customer = customerMap.get(“0001”);
If(customer==null){
customerMap.insert(“0001”, ”Insert UserName_Freud”);
}else{
customerMap.update(“0001”, “Updated UserName_Freud”);
}
Customer = (String) customerMap.get(“0001”);
System.out.println(“The customer Name is : ” + customer);
7. Parallel query
Waiting to be edit…
8. Map Agent
Waiting to be edit…
9. Add Index
Waiting to be edit…
10. Relationship – Cascade (Waiting to be edit…)
One to one
One to many
Many to one
