My SUNRAY seems frozen
Occasionally a SUNRAY machine will seem frozen. -No mouse or keyboard interaction.
If this doesn't help
If the system still looks frozen
When none of this works contact KenB or Jingchen to reset the login session via the web interface.
Why won't Firefox start? It gives me this message when I try to start it: "Firefox is currently running, but is not responding. To open a new window you must first close the existing firefox process" - but I don't see firefox on my desktop!
This sometimes happens on a Taylored Linux machine, eg. in your office. It probably has to do with it's using AFS, whose tokens expire every 25 hrs.
You need to delete the ".parent" lock file. You'll find it in a temporary directory, which is itself in $
/.mozilla/firefox/. Eg
[esdslx01]:.mozilla/firefox/7b2eaes1.Default User> rm .parentlock
Sometimes I can't launch an EPICS display from the SCP?
There are three variations of this problem, depending on whether you're on a kiosk machine (one of the Linux boxes presently mostly used in the control room), or not. If you are a kiosk machine, then you can not launch PEP-II EPICS displays but you can launch LCLS displays. If you are on a COW, WindowsPC, or SunRay, then you can launch both PEP-II EPICS displays and LCLS displays. If you are on an Taylored Linux machine, then you can not launch PEPII or LCLS displays. ie, kiosk == LCLS but not PEPII, not kiosk == PEPII and LCLS (except Taylored Linux == !PEPII and !LCLS).
The reasons are different for each restriction. You can't be on a kiosk machine to launch pepii displays because the command is being sent from the scp to cmdSrv running on the kiosks to execute the cs script indicated on the panel code line. That cs script is a pepii script. It not only invokes the pepii environment, but it runs an executable which was built for solaris which won't work on the linux kiosks. So, the idea is that new buttons will be added to the LCLS scp panels which invoke cs scripts that live in the lcls tree. These new buttons will use LCLS command server classes. You can't launch PEPII or LCLS displays from Taylored Linux because of of security restrictions related to Taylored machiens. See Terri Lahey and Ron MacKenzie for details.
