Hi Hany,

Following are the steps to increase heap size in java-

Step1:- *Go to Control Panel.* Click on "Start" button. Then click on "Control Panel." Step2:-*Go to Java settings.* In the next dialog click on "Java," usually at the bottom of the other Programs; "Java Control Panel" dialog pop-up opens. Step3:- *Select "Java" tab.* Inside the Java tab, click on "View" button. It opens the "Java Runtime Environment Settings" Step4:-*Change amount of heap.* In the "Runtime Parameters" column change the value, or if it is blank decide for the new value, of the Java memory. Step5:-*Modify the parameter.* To modify the parameter, double click in the "Runtime Parameters" column and,

           type -Xms512m - that assigns 512MB memory for the Java.
           type -Xms1024m - that assigns 1GB memory for the Java.
           type -Xms2048m - that assigns 2GB memory for the Java.
type -Xms3072m - that assigns 3GB memory for the Java, and so on.

 * Please note, it begins with a minus sign and ends to an m.
 * Also note, there is no blank space between characters.

Kindly confirm after increasing the heap size the issue is resolved or not.

Thanks and Regards
Monika Ashtewar
