Pinned topic ISA 5 Beta XVFB on Linux is a no go!

‏2013-06-17T07:44:39Z |

Hi, so far ISA 5 Beta 3 Teamserver requires XFVB on Linux Servers. This is a absolute no go in our environment!

Any plans to cleanup the software to run with AWT-Headless in future?

    Hello Oliver,

    XVFB is not required for ISA proper, but only for some add-on tools. Please help us understand why XVFB is a no-go for you.

    Thanks,

    Rick

      We run some older applications in WebSphere using XVFB, because they use AWT functions not supported with AWT-Headless. This environment is highly unstable!
      If XVFB is restarted the WebSphere needs to be restarted. If WebSphere is started before XVFB, connection from WebSphere to XVFB fail....

      We plan to run ISA 5 on a Linux Server used by all members of WebSphere Support Teams inside the enterprise. With our bad experience XVFB we would like to see a more stable design. Special since ISA is used when we have a problems - solving the problem has high prio - we don't like to spend time for solving problems with problem solving tool in this situation.

        Oliver,

        First, let me reiterate that XVFB is only required for some add-on tools. For example, GCMV.

        1. "If WebSphere is started before XVFB" -- In our Linux environments, we start XVFB at system init. From /etc/inittab:

        # X11 virtual frame buffer
        vfb:2345:respawn:/usr/bin/Xvfb :1 -screen 0 1024x768x16
         

        That way, it is always available when one of these add-on tools is started.

        2. "If XVFB is restarted the WebSphere needs to be restarted." -- Those add-on tools that do require XVFB are in all cases report generators that run as standalone OS processes. That process is exec'd on demand, when the ISA user "launches" that tool. So, there is really no need for any ISA component to be restarted in the event that XVFB is restarted.
