Posted by postprob on February 01, 2010 at 04:33 PM
Problem: Extremely slow response from some Oracle databases Cause: runaway process, possibly triggered by earlier network outage Affects: Many applications--see Notes below Started: 02/01/2010 03:15 PM Resolved: 02/01/2010 04:02 PM
Notes:
The non-ERP production Oracle database server suffered severely degraded performance this afternoon. The root cause has not been determined, but one database instance had spawned an excessive number of processes and had to be stopped & re-started in order to restore the system to normal operation.
Affected applications include (but are not limited to):
Ad Astra
BlackBoard (Course mgmt. system)
Dental School Clinic
Identity Management (user account/password changes)
IP address/host name management
E-mail lists
MyCase portal
Pinnacle (phone billing)
University Library web sites (not including EuclidPLUS/on-line catalog system)
DARS
ProSam (Financial Aid)
Encyclopedia of Cleveland History
Internal IT applications: Appworx, ChangeMan, Mashups, VirtualCenter
The PeopleSoft Student ERP system was also affected indirectly (due to a database link to one of the affectd DBs).
