After upgrading to Spectrum 10.4.0 and spectrumgtw 8.68 alarms are no longer being synched between UIM and Spectrum.
Component : UIM - SPECTRUMGTW
spectrumgtw 8.6.8. was tested only with Spectrum 10.4.2.
If you do not wish to upgrade the Spectrum 10.4 installation to SP2/10.4.2, you may apply spectrumgtw 8.67-HF6 (or higher if available.)
This can be obtained from the UIM Hotfix Index website.
