Running ocean jobs without starting X server

ebecheto

Dear All,

I am necroposting about the following subject. Since the post (https://community.cadence.com/cadence_technology_forums/f/custom-ic-design/23238/running-ocean-jobs-without-starting-x-server)

is close, i start a new thread.

ocean -nograph -log log   -restore script.ocn  # FAILED

LOG :

Fatal server error:
could not open default font 'fixed'

__END_CAT

So what i understand is that ocean start a vnc server to swallow the Xdisplay stream. But the vnc server fail because our cluster have not installed the font.

That's normal, a computing grid should not have font.

My question is : Can IC6 embedded the font to prevent such failure ?

I am waiting for the font to be installed to see if it fixed the issue.

    During IC6.1.8 we switched from using cdsVncServer to using Xvfb instead, and I don't believe you need the fonts any more. So my recommendation is to mote to a recent IC6.1.8 version instead (although you will need to ensure that Xvfb is installed on your OS - generally OK if it's recent enough).

    If you're stuck with the old version you're using, you will need to have the fonts installed - that's the way it is.
