Updating our preprod environment to 2018 Q4 CU3

A quick post about our preprod upgrade to 2018 Q4 CU3.

We experienced the same ORA-00001 error I reported in Upgrading two dev environments to 2018 Q4  this time we tried running the installer again.  The row conflict PK1 it reports went up by 1.  Running the installer a third time it reached a vacant row and proceeded.  So next time we know to keep running the installer until it works (if only all workarounds were so simple).

The upgrade went smooth.  We found that a few fixes we were applying were no longer necessary, specifically the XSS fix (the bb-file-filter-configuration.properties file is good on 2018 Q4), the Safari upload fix, the Xythos Cross Server Communication Fix, the Forum is enabled issue, and the JDK 1.8.0_151 and 1.8.0_152 Break Grade Center issue fixes were no longer required).

The main new setting I had not realised we had to set was via the GUI:
System Admin - Cloud Connector Settings - Regional Cloud.

Although we have set bbconfig.cloud.lms.region=eu-west-2 in bb-config.properties, because support told us to use the closest location to us listed in Regions and Availability Zones - Amazon Relational Database Service We also had to set the regional cloud setting through the GUI, which only has a limited number of locations available, not matching those in Regions and Availability Zones - Amazon Relational Database Service - only one European location is available in the GUI compared with 5 on the Amazon listing.

Hopefully the difference will not cause a problem later...

Blackboard tests are a hot topic at the moment. I recently recently received a question from Dr Gabriel Weymouth : "I'm positive this is clearly documented somewhere, but I can't find it. How do you make BB apply the correct error margins for calculated formula problems. The logical way of doing it (setting a, say, 2% margin) doesn't work:"

My updated theme for Blackboard 3800.13

As we move to SaaS soon I had to update our theme work to be compatible with the latest SaaS version. So this means I have a nice freshly compiled version to share.  The previously shared version had been lost in the transfer to the new Blackboard Community Site. This explains why I now back up all new posts to both this blog as well as posting on the community site.  A lack of time means that right now I cannot share screenshots of how the new additions to the theme look, but I am providing the source code below so you can experiment with copying and pasting them into Stylus easily, without having to unzip the theme. You can get a good idea of how it all looks by referring to my post: Let me show you my Blackboard . Watch this video for a guide on how to try the theme out without having to install it: Note that the improvement to Review Status required me to apply a separate CSS just for instructors. In Blackboard the review status button has a double purpose when making a test
