Missing Shutdowns

A Weblogic managed node for a development cluster failed to shutdown when our shutdown script requested. The last managed node to shutdown becomes the JMS node and triggers a rewrite of the config.xml. We have scripts in place to check for the config.xml changing and alert us. Since I am the on call this week,… Continue reading Missing Shutdowns

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… Continue reading xmllint

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… Continue reading Weblogic Diagnostics

Mail From Address

It appears CE/Vista has several locations for defining the email addresses it uses for SMTP. $WEBCTDOMAIN/config/config.xml: mail.from= From address for messages sent. $WEBCTDOMAIN/customconfig/startup.properties: WEBCT_ADMIN_EMAIL= Some internal errors have a mailto: prompt to contact the server administrator. $WEBCTDOMAIN/serverconfs/log4j.properties: log4j.appender.EMail.To= Report fatal errors. $WEBCTDOMAIN/serverconfs/log4jstartup.properties: log4j.appender.EMail.To= Report fatal errors. $WEBCTDOMAIN/webctInstalledServer.properties: WEBCT_ADMIN_EMAIL= Installer picks up this value for populating… Continue reading Mail From Address

Rock Eagle Debrief

GeorgiaVIEW SMART (Section Migration Archive and Restore Tool) created for us by the Georgia Digital Innovation Group seemed well received. I’m glad. DIG worked tirelessly on it on an absurdly short schedule. Information is strewn about in too many places. There isn’t one place to go for information. Instead between Blackboard, VistaSWAT, and GeorgiaVIEW about… Continue reading Rock Eagle Debrief

More IMS Import Headaches

I got this error while trying to run an XML IMS import using the WebCT / Blackboard CE/Vista siapi.sh script… A unit of type Institution cannot have a unit of type Campus as a child. Guess being on vacation last week spaced my neurons. Normally, I ignore Blackboard errors as meaningless. This time I listened… Continue reading More IMS Import Headaches

Granting a Student (Not All) Access

Problem: The “Restrict access after this date” function affects all students and auditors without individual exceptions. In reality, universities need to grant individual exceptions for Incomplete grades, grade challenges, or other special cases. Solution: A Section Instructor could select all the students except the one who needs access and Deny access to them. Then the… Continue reading Granting a Student (Not All) Access

Please verify the admin user and password

So, I got this error… Unknown WebCT username or invalid password. Please verify the admin user and password in the IMS Settings. I assumed the username and password were probably right. I had to find my error somewhere else. The error turned out to be one missing character out of the 57 character long glcid.… Continue reading Please verify the admin user and password
