I have a script on a remote clearcase server which I execute using paramiko invoke_shell.The script contains a cleartool findmerge command graphical but the graphical window never opens though I used x11 forwarding. It waits forever.I even added the checkout comments for the merge. I want the graphical window to be opened.

It depends how you did setup your X-forwarding: see this thread for example:

  1. Launch Exceed
  2. Launch Putty
    • In the putty configuration window, select Connection, then SSH, and then X11 from the left side menus.
    • On the right side, select the checkbox for Enable X11 forwarding and set the X display location to "localhost:0" .
    • In the putty configuration window, select Session from the left side.
      Enter the hostname of a system to connect to Select the SSH protocol
      Save settings by selecting the Save button on the right.
    • Invoke session by double-clicking on hostname
  3. from the server, run "export DISPLAY=windows ip:0"
  4. You should be able to run any X-based tool or application
    e.g. clearprojexp &

The OP Srikar Veeramallu mentions in the comments:

I am in a dynamic view set using cleartool setview

That explains why it "waits forever". A setview will create a sub-shell, which might not benefit from the same X11 forwarding as the main shell.
See "Python and ClearCase setview" for more details.

The workaround is to use the full path of the view.

  • With putty this works fine. But when I run it with python using paramiko module to connect and execute commands. The issue I mentioned above is encountered – Srikar Veeramallu Feb 23 '15 at 08:16
  • @SrikarVeeramallu are you in a dynamic view set with `cleartool setview` in your python session? – VonC Feb 23 '15 at 08:21
  • yes I am in a dynamic view set using cleartool setview – Srikar Veeramallu Feb 23 '15 at 09:08
  • @SrikarVeeramallu I knew it! Simply put: never use `cleartool setview`. Ever. It only brings trouble. Always use the full path of the dynamic view. See http://stackoverflow.com/a/27826673/6309, and, for more details: http://stackoverflow.com/a/10252612/6309. – VonC Feb 23 '15 at 09:22
  • @SrikarVeeramallu I have edited the answer and added the workaround. – VonC Feb 23 '15 at 09:58
