CAPC models not mapped in Spectrum Oneclick

Customers may see an issue with launching into CAPC from Spectrum.

Error seen in CAPC is that Context ID is not a valid number or it loads a device that is incorrect.  When looking at CAPC_Item_Id on the model in OneClick, it will be 0 or the wrong number.


Spectrum was removed and re-added as a datasource at some point.


Spectrum stores CAPC<->OC model mapping in netqos_integ item_model_mapping table and in a in-memory cache on OneClick server.  When Spectrum is deleted as a Data Source, this cache nor the table are cleared out.   So when Spectrum is re-added as a datasource, the cache believes we have already synced the model and it will not write a new value to CAPC_Item_Id on the model in Spectrum.


On OneClick server, stop the tomcat service.  Use mysql and connect to netqos_integ database.  Run the following sql command: truncate item_model_mapping;    Exit mysql, and start the tomcat service.  When Spectrum connects to CAPC, it will basically do a full sync and repopulate the item_model_mapping table and in-memory cache, which will cascade to CAPC_Item_Id attribute on models synced.

Other effects:  

This can also cause events to not be sent to the correct model.  If the item_model_mapping table is incorrect or not updated correctly, the events would be mapped to the wrong Spectrum device or no device at all.
