Resolution

A hotfix is available and has been attached to this KB.   (prediction_engine-23.4.5-_hot_fix_2_DE646481.zip)

this hotfix must only be applied to a DX UIM 23.4.5 (CU5) environment.  This fix is already included in CU6.

Instructions to deploy:

• deactivate prediction_engine
• save a copy of the file "ttt_definitions" which is found in the folder /Nimsoft/probes/slm/prediction_engine/
• right-click and delete prediction_engine in IM
• delete the left over folder /probes/slm/prediction_engine/
• go into the Hub GUI And look for the prediction_engine.PREDICTION_CONFIG and prediction_engine.QOS_MESSAGE queues
• if the prediction_engine.QOS_MESSAGE queue is defined here, delete it, but leave PREDICTION_CONFIG alone.
• click ok/restart hub
• deploy prediction_engine hotfix
• activate the probe and verify that it subscribes successfully to prediction_engine.PREDICTION_CONFIG --- the QOS_MESSAGE queue will not appear yet
• deactivate the probe after confirming
• now drop the copy you took of the ttt_definitions file back into the prediction_engine folder
• activate the probe
• at this time the prediction_engine.QOS_MESSAGE queue should appear and will have been re-added to the hub.cfg

Additional Information

This will be included as a fix in the upcoming CU6 (23.4.6) release.
