Environment: OM 6 (not the latest version) mariadb Ver 15.1 Distrib 10.6.5-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2
Steps of testing: STEP 1: creating 20 new whiteboards (this can be ONE lesson in a course) STEP 2: saving all whiteboards (SAVE button) STEP 3: exit the room STEP 4: assign all 20 whiteboards to ONE room (administration/conference rooms) STEP 5: exit OM STEP 6: restart OM-Tomcat STEP 7: enter OM and check the given room which should contain the 20 WBs My result: - some whiteboard contents were missing completely(only the empty WB) - some whiteboards were not complete (part of the content was missing) - I could put back the missing whiteboard manually, but not always - sometimes (error message): "something bad happened, check log, contact the developers" Evaluation: - the Java module handling this part of the database is suspicious (to protect the database consistency "10.6.5-MariaDB" would be able to give more support /transaction/) Notes: - I tested the same OM 6 on two different Ubuntu 18.4 servers - RAM in the first server: 6 Gbyte - RAM in the second server: 8 Gbyte - the result was the same on both servers Possible next step: - someone in this community could do the same test (optimally with the latest "official" OM version) QUESTIONS: What do you think about this test case? What is your opinion about creating/managing (lesson) content in OM? (digital OM-Whiteboard means you can create your material in advance which can include videos, too) (Reference number of this message: 2022-01-09-13-08-47)
