Mail Delivery Background Jobs
Only 8 years into running this product and I still learn something new about it. Monday there was an event. Two nodes became responsive at about the same time. The other ten nodes did their jobs and transferred session information to the nodes taking on the sessions. Most were so busy they did not respond…

OrgCode Duplicate Filter
I was asked to work my “Unix magic”. The problem? Duplicate courses were spooled and converted from the WebCT format to the Desire2Learn. The conversion process creates an import file using the WebCT SourcedId.Id as the OrgCode. The first time the OrgCode is used, it creates a course. The next and subsequent times, it duplicates…

Whenever I have been in a conversation with a BEA (more recently Oracle) person on Weblogic, the number of nodes we run has invariably surprised them. Major banks…

(Thankfully we have lots of development clusters for me to break beyond repair. Kidding. Sorta.) One of the common support questions Blackboard asks for those of us CE/Vista clients running…

xmllint
This Linux tool is my new best friend. We get thousands of XML files from our clients for loading user, class, and enrollment information. Some of these clients customize our software or write their own software for generating the XML. This means we frequently get oddities in the files which cause problems. Thankfully I am…

Weblogic Diagnostics
I noticed one the nodes in a development cluster was down. So I started it again. The second start failed, so I ended up looking at logs to figure out why. The error in the WebCTServer.000000000.log said: weblogic.diagnostics.lifecycle.DiagnosticComponentLifecycleException: weblogic.store.PersistentStoreException: java.io.IOException: [Store:280036]Missing the file store file “WLS_DIAGNOSTICS000001.DAT” in the directory “$VISTAHOME/./servers/$NODENAME/data/store/diagnostics” So I looked to see…

Open Schema
If Blackboard opens up the schema for Vista 8, then maybe I’ll feel more comfortable sharing the reporting SQL I use. Ron Santos has a good PowerPoint on SQL for reports at Simon Frasier University.
