Solaris 10, Oracle 11.2 and Blackboard 9.1 SP8
We've been having ongoing performance issues which we're struggling to bottom out. Our sys admin and Blackboard can't identify anything wrong and the servers appear to be under no load with plenty of resources. With a 'normal' number of enrolments (say 20) the service does seem to be noticeably sluggish since upgrading to SP8 but only marginally so and we have no metrics to definitively prove it. When a large number of enrolments are involved (say 400+) the system starts to grind to a halt and becomes close to unusable. I'm guessing that's why our most persistent complaints come from admin staff with a large number of enrolments. I've wondered if this has something to do with the 'course-to-course' navigation feature? Has anybody else experienced anything similar?
Also, does anybody have any opinions on whether the number of enrolments would/should significantly affect performance for a user? Are we unusual in having staff who need access to courses across a school and, as a consequence, have many 100s of enrolments?
Thanks,
Neil
