  • Better CE/Vista Web Server Log

    Some support tickets are more easily solved by knowing both user behavior and environment. An often helpful piece of information is what web browser they used. To add this, shut down the cluster, edit /VISTA_HOME/config/config.xml to include the cs(User-Agent), and start the cluster. This line will need to appear for every node. At startup, the…

  • Forcing Weblogic’s Config.xml

    Let’s nevermind why I am working on this in the first place. Namely… the Blackboard Learning Environment Connector introduced using the hostname and port for applet URLs in Vista 8 Blackboard, Blackboard dropped WebCT’s support for using a different port for an application when behind a load balancer.

  • CE / Vista Undocumented Workspaces

    On the WebCT Users email list (hosted by Blackboard) there is a discussion about a mysterious directory called unmarshall which suddenly appeared. We found it under similar circumstances as others by investigating why a node consumed so much disk space. Failed command-line restores end up in this unmarshall directory. Unmarshalling in Java jargon means: converting…

  • Assignments Spike CPU

    Yesterday a Blackboard Vista node went unresponsive but recovered. Then a second and third did the same. This was odd as only the test which logs into the node reported a failure. Normally, in severe unresponsive cases the Weblogic monitor either reports either one of the parameters we watch is very high or fails because…

  • BbWorld Presentation Redux Part II – Monitoring

    Much of what I might write in these posts about Vista is knowledge accumulated from the efforts of my coworkers. This is part two in a series of blog posts on our presentation at BbWorld ’07, on the behalf of the Georgia VIEW project, Maintaining Large Vista Installations (2MB PPT). Part one covered automation of…

I’ve decided to do a series of blog posts on our presentation at BbWorld ’07, on the behalf of the Georgia VIEW project, Maintaining Large Vista Installations (2MB PPT). I wrote the bit about tracking…
