Hi,
Yesterday our SAP BI based portal server suffered a dramatic decrease of perfomance that prevented reports to be viewed (users were able to login into portal, but when clicked on a given report it showed the clock progress bar with no results..) . We finally decided to restart all the servers in order to try to workaround the situation. Luckily it works but I am focused in trying to understand what cause the issue.
We have been reviewing the performance counters of all involved servers (CPU, Memory consumption) duing the period of time when the issue appeared and we don't find any quick explanation. Our more intersting clue are the info contained in the BO server tace files (*.glf files) , and particularly the WebIntelligenceProcessingServer trace.
At the time of the issue (and several minutes before) the next list of errors were triggered repeteadly
**ERROR:cdzContext:ExtensionManagementException has been raised [cdzContext.cpp;1193]
**ERROR:cdzContext:All the servers with CMS es-w08-bient1:6400, cluster @es-w08-bient1.f4e.org:6400, kind pjs which host service DSLBridge, are down or disabled [cdzContext.cpp;1194]
**ERROR:DSLBridgeController:BrigdeController::getDslBridge : the IExtension reference is null [src/DSLBrigdeController.cpp;157]
**ERROR:DSLBridgeController:Error: Failed to load SL Service extension
I suspect that we have some configuration issue related with the WebIntelligenceProcessingServer but by reviewing the data provided by the monitoring application (Memory max threshould count,....) we don't see which would be the cause of the stuff.
Any idea? Thanks for sharing your thoughs.
