Java.lang.OutOfMemoryError: Java heap space While deploying 'ear' file

Question

I am using below code to deploy an 'ear' file on weblogic 10.3
package com.qasource;
import java.io.*;
import java.util.Hashtable;
import weblogic.deploy.api.tools.*;  //SesionHelper
import weblogic.deploy.api.spi .*;  //WebLogicDeploymentManager
import javax.enterprise.deploy.spi.TargetModuleID;
import javax.enterprise.deploy.spi.status.ProgressObject;
import javax.enterprise.deploy.spi.status.DeploymentStatus;
import javax.enterprise.deploy.shared.ModuleType;
import javax.enterprise.deploy.spi.Target;
import javax.management.MBeanServerConnection;
import javax.management.remote.JMXConnector;
import javax.management.remote.JMXConnectorFactory;
import javax.management.remote.JMXServiceURL;
import javax.naming.Context;
public class WeblogicTest
     public static void main(String ar[]) throws Exception
          System.out.println("Start Deploying");
          WebLogicDeploymentManager deployManager=SessionHelper.getRemoteDeploymentManager( "t3", "10.0.0.47", "7003", "weblogic",
          "weblogic123");
          System.out.println("Deploy Manager  :  " + deployManager);
          DeploymentOptions options = new DeploymentOptions();
          options.setName("TC33");          //TODO
          Target targets[] = deployManager.getTargets();
          System.out.println("Target  :  " + targets);
          Target deployTargets[]=new Target[1];     
          int temp=0;
          for (temp=0; temp < targets.length; temp++){
               if(targets[temp].getName().equals("new_ManagedServer_1")){
                    deployTargets[0]=targets[temp];
          ProgressObject processStatus=deployManager.distribute(deployTargets, new                
                    File("\\\\10.0.0.47\\Builds\\VertexTest\\domain1\\tc3.3b74_6.2.2011.19\\test-3.3.0.0074.ear"), null,options);
          DeploymentStatus deploymentStatus=processStatus.getDeploymentStatus() ;
          System.out.println("UnDeploymentStayus.getMessage(): "+deploymentStatus.getMessage() );
          Thread.sleep(5000);
          TargetModuleID[] targetModuleIDs=deployManager.getAvailableModules(ModuleType.EAR, deployTargets);
          System.out.println("\n\t targetModuleIDs [] = "+targetModuleIDs);
          for (int j=0;j<targetModuleIDs.length;j++){
               System.out.println("\n\t "+targetModuleIDs[j]);
               deployManager.start(targetModuleIDs);
               deployManager.start(targetModuleIDs);
}My environment: Window XP
Weblogic: 11g
ear file size: 97886 KB
Admin server arguments: -Xms=512m Xmx=512m
Managed server arguments: -Xms=512m Xmx=512m
But above code is showing java.lang.OutOfMemoryError: Java heap space:
below is the log statements:
Start Deploying
Deploy Manager : [email protected]eb5

Answer 1

Hi,
Yes,René van Wijk has said rite..
Just open the Weblogic console,
expand Environment-->Server-->(ur managed server)-->Server Start tab
Just enter the below lines in Arguments:
-Xms1024m -Xmx1024m -XX:MaxPermSize=256m
Then bounce your managed server
This should solve your problem
