UIM 8.51 with Spectrumgtw probe v8.65 connecting to a Spectrum server 10.2.3.000. "BI-DIRECTIONAL" alarm sync has been selected, but UIM alarms under Spectrum OneClick, and Spectrum alarms are not seen in the UMP Alarm View. When looking at the Spectrum OneClick console we do see alarms from UIM being created. The problem is just Spectrum alarms to UIM.
In the EMS.log we saw SQL exceptions regarding inserting data into the NAS_ALARMS table.
Spectrum 10.2.3 Integration set to 'SpectrumGateway Integration' in OneClick Web Interface
It appears that the backend NAS tables were not altered adding new columns introduced and needed by EMS 10.1x and NAS 9.x. This was causing the inserts to fail and the alarms therefore were not visible.
