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]

--------CatalogServer Arguments-------------------------------

-catalogServiceEndPoints <server:host:port:port,server:host:port:port>

-quorum true|false

-heartbeat 0|1|-1|10|-10

-clusterSecurityFile <cluster security xml file>

-clusterSecurityUrl <cluster security xml URL>

-domain <domain name>

-transport <ORB|XIO>

--------Common Arguments-------------------------------

-listenerHost <hostname>

-timeout <seconds>

-script <script file>

-jvmArgs <JVM arguments>

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:

StartXsServer.bat  ${container_Server_name}  -objectgridFile ${file_name or  location} –catalogServiceEndpoints  localhost:2809

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" 



     xmlns="http://ibm.com/ws/objectgrid/config">



    <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"

     xmlns="http://ibm.com/ws/objectgrid/deploymentPolicy">

 

     <objectgridDeployment objectgridName="accounting">

            <mapSet name="mapSet1" numberOfPartitions="1" minSyncReplicas="0" maxSyncReplicas="2" 

                    maxAsyncReplicas="1">

                    <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
