  • solr administration

    - by devrick0
    Does anyone have any notes for an sysadmin supporting solr? I'm looking for anything that might be useful for monitoring & metrics as well as troubleshooting. Some useful links I have found are: /solr/admin/stats.jsp and /solr/admin/analysis.jsp In the logs I have noticed, other than the query, "hits", "status" and "QTime" values. The documentation on what these mean is sparse at least based on the 100+ websites I have checked. QTime appears to be the query time response in milliseconds. Hits is some form of results but I'm not sure exactly what makes that up and I'm not sure about status. Typically I see status come back as "0" but I have seen other numbers such as "5", so my thoughts that it could be either HTTP status codes or a 0 or 1 (good or bad) methodology isn't accurate. All of the documentation I have come across is intended for developers. Any sysadmin-centric documentation would be a big help.

  • Premature end of script headers

    - by Tony
    I often get a "premature end of script headers" error in my apache log which results to an internal 500 error. I understand what the error message means - that my application did not give the browser the headers it needs (and maybe nothing at all), but the odd thing is that this does not happen all the time. It actually usually happens the first few times I go to my website after a deploy. Could this be a memory issue? Does anyone know how to trouble shoot this? My apache log isn't really telling me anything. I am running a ruby site using the rails framework on ubuntu hardy. thank you!

  • Tomcat cannot connect to MySQL on localhost

    - by David
    Hi, I have deployed an application on my Tomcat server with JDBC resources defined. What is puzzling me is that I can connect to the database (which is running locally on the server) only using the server's IP. When I change the resource host to localhost (or 127.0.0.1) then MySQL rejects the connection. I don't want to be connection via the server's IP but rather locally. What do I do? Thanks!

    I have a function foo on my local Machine. (In my profile, but calling c:\scripts\foo.ps1 would be also OK!)

  • Dell D620 Windows 7 Blank screen

    - by Dave Arkell
    When I installed Windows 7 on my Dell D620 it was all fine until a couple of days later most times when I either shut down or suspend (by closing the lid). When I unsuspend or startup the computer, there is often a completely blank screen (can't see post screen or anything), and restarting doesn't help. I've found that I can eventually bring it back up again by suspending and unsuspending a few times, but obviously this is not ideal. Has anyone else experienced this? I think it is a driver issue, that somehow the driver is putting the video card into a certain mode that it forgets how to get it back out of. Any ideas on a better solution than my switching off and on business? Edit: Turns out that the video card had burned out! IT managed to get me a new mainboard sorted for me.
