Yes, it also happens after I migrated the VC DB into to the new server.
I've got:
There was an error connecting to VMware vCenter Update Manager 8084 Database temporarily unavailable
XXX com.vmware.vcIntegrity.SigUpdateTask.label not found XXX
vCenter01.domain.com
Queued
VMware vCenter Update Manager Update Download
this is on Windows Server 2003 Std. x64 with SQL Server 2008 Std x64 running vCenter 4.0 u1
can anyone clarify how to fix this please ?
