Notes:
In some cases, the Serenity database becomes corrupt, reset Serenity DB to resolve the issue.
The impact of resetting the Serenity database is very tiny -- when connecting to the vCenter through the web client, it will take a few seconds longer than usual while the system rebuilds that database.
Follow the below steps:
# service vsphere-client stop
rm -rf /etc/vmware-vsphere-client/SerenityDB/serenity/*
# service vsphere-client start
# service-control --stop vsphere-client
rm -rf /storage/vsphere-client/SerenityDB/serenity/*
# service-control --start vsphere-client
# service-control --stop vsphere-ui
rm -rf /storage/vsphere-client/SerenityDB/serenity/*
# service-control --start vsphere-ui
# cd <C:\Program Files\VMware\vCenter Server\bin>
# service-control --stop vspherewebclientsvc
<C:\programdata\vmware\vCenterServer\data\vSphere Web Client\SerenityDB\serenity>
#service-control --start vspherewebclientsvc
