6.3 Issues in Jenkins

One of the error which i faced while running jenkins is:-

Issue 1: Unable to set the workspace

Scenario: In jenkins if we are unable to set the workspace as you are not the administrator sometimes we cannot run the tests.

Solution: There is an advanced field at the time of project setup where in you must select custom workspace option in jenkins so as to run tests from the specified workspace.

Issue 2: Error occurred during initialization of VM

Scenario: First of all, I have a box with 8gb of ram, so I doubt total memory is the issue. This application is running fine on machines with 6gb or less.I am trying to reserve 3GB of space using -Xmx3G under "VM Arguments" in Run Configurations in Eclipse. Every time I try to reserve more than 1500mb, I get this error: “Error occurred during initialization of VM; Could not reserve enough space for object heap” using -Xmx3G

Solution: Here is how to fix it:

Go toStart->Control Panel->System->Advanced(tab)->Environment Variables->System

Variables->
New:
Variable name: _JAVA_OPTIONS   
Variable value:-Xmx1024M
Variable name:Path
Variable value:;C:\Program Files\Java\jre1.8.121\bin;C:\JDK\bin;

Please let me know if you had any other issues
