How can we install Java Console on rhel 6.2

Environment

OS = rhel6.2

Java console version = 6.0 SP1

Problem

I am able to install the java console but getting error when running the hagui.

How do I installed. See below for reference:

rpm -ivh /home/zahid/Desktop/VCS_Cluster_Manager_Java_Console_6.0.SP1_for_Linux.rpm
Preparing...                ########################################### [100%]
   1:VRTScscm               ########################################### [100%]


Error when running hagui :

Java Console is installed on the cluster Node (Single cluster but took ssh session to run the hagui)

[root@cluster-pri ~]# /opt/VRTSvcs/bin/hagui
Exception in thread "main" java.awt.HeadlessException:
No X11 DISPLAY variable was set, but this program performed an operation which requires it.
    at sun.awt.HeadlessToolkit.getColorModel(Unknown Source)
    at VCSGui.getImage(VCSGui.java:59)
    at VCSGui.main(VCSGui.java:92)
 

Java Console is installed on the cluster Node (Single cluster Node and running hagui on the Desktop of Single Cluster Node)

[root@cluster-dr ~]# /opt/VRTSvcs/bin/hagui
VCS Single Cluster Manager (Java Console) is no longer packaged with VCS. Symantec recommends use of the Veritas Operations Manager (VOM) to manage, monitor and report on multi-cluster environments. You can download VOM at http://go.symantec.com/vom . If you wish to continue using the VCS Single Cluster Manager, you can get it at no charge at the http://go.symantec.com/vcsm_download website.

    This should also exist in /usr/lib.  The java GUI is a 32-bit program so will be looking in /usr/lib (or maybe /usr/lib32). You probably need to install the 32bit package so probably named libXext-1.1-3.el6.i686

    Hi Zahid,

    As the error mentions, did you try setting up the DISPLAY variable pointing out to where should be console go ?

    I understand you are running the hagui directly on server ... you need to redirect the console to some display machine

    If you want the console to appear on your desktop or laptop, you have to use a X software like Xming or X manager & make it to listen to display requests ..

    then on server, you need to set DISPLAY variable like  DISPLAY=<IP_ADDRESS_OF_LAPTOP>,0.0 

    check out the display port what it is listening with your X software (it should appear in systray) ..

    Once display is set, then re-trigger ... it should throw theGUI on laptop or desktop ...

    Zahid,

    You also want to make sure that your putty session (or other SSH Client) has the "X11 Forwarding" option selected.  See the attached screen capture from putty.

    Why are you trying to run hagui on the cluster nodes.  The normal reasons for this, is you are logging on to the PHYSICAL VGA console (which is pretty rare these days as you mainly ssh to server remotely) or you do not have permissions to install client on you client computer.  If the reason is either of these, then you need to set DISPLAY variable.  However, it is better to install java console on your client (less network traffic between server and client so it is quicker and you can manage both clusters from the same client). Normally the client is Windows so you can download this or install the rpm you already have on you client if it is a Linux client with rpm package management - both of these can be downloaded from  http://go.symantec.com/vom as the DR nodes tells you on which presumebly you have not installed the Java console.

    Download the Java GUI for your Windows desktop.

    Much easier than trying to install and manage on cluster nodes....

    I can install on windows machine and I feel that its much easier but the person who will administer the Cluster is a Linux OS person. This is actually the prob...

    OK, so you say you already did the same as we recommended above ..

    1. X11 forwarding enabled

    2. DISPLAY variable set correctly ..

    3. X manager software installed

    Do u see any GUI on laptop or not at all see anything ? any network security softwares in between which prevents X from coming ?

    To eliminate the problem, can u simply try runnig xclock on your linux server with same display & X 11 forwarding enabled ? if there is an issue between network , you should NOT see the x clock also ...

    atleast you would know where to go from here ..
