Primary SpectroSERVER Archive manager is shown down for some reason as well as secondary spectrosevrer is also down.
Checking the "Archivemanager" tasks (ArchMgr executable) is active in the task-list and ./SS/DDM/ARCHMGR.OUT looks fine.
Communication facility / toolset used to establish communication for Oneclick-server to ArchiveManager is the CORBA toolset.
Means - the OneClick server implementation is checking and "registering" to the ArchMgr-CORBA resource object running at the SpectroSERVER host.
The CORBA resource object name is CsCEventDomain.
Make use of tool -> ./bin/VBNS/ nsutil list <hostname> to list the available CORBA objects/resources when all Spectrum services are running.
It appears under very rare conditions, the ArchiveManager startup is fine and runs stable but the CORBA resource object CsCEventDomain is not created.
This then causes at OneClick service to show the ArchiveManager (Events) being down.
This applies to all CA Spectrum releases and used installation platform
