Set the Maximum Number of Database Connections After a vCenter Server
Upgrade
By default, a vCenter Server creates a maximum of 50 simultaneous database connections. If you congure
this value to less than 50 in the previous version of vCenter Server and then perform the upgrade to vCenter
Server 5.x, the upgrade restores the default seing of 50. If you congure this value to more than 50 in the
previous version of vCenter Server, after the upgrade to vCenter Server 5.x, the system retains the previous
value. You can recongure the nondefault seing.
You might want to increase the number of database connections if the vCenter Server frequently performs
many operations and performance is critical. You might want to decrease this number if the database is
shared and connections to the database are costly. Do not change this value unless your system has one of
these problems.
Perform this task before you congure the authentication for your database. For more information about
conguring authentication, see the documentation for your database.

Setting the vCenter Server Administrator User
The way you set the vCenter Server administrator user depends on your vCenter Single Sign-On
deployment.
In vSphere versions before vSphere 5.1, vCenter Server administrators are the users that belong to the local
operating system administrators group.
In vSphere 5.1.x, 5.5, and 6.0, when you install vCenter Server, you must provide the default (initial)
vCenter Server administrator user or group. For deployments where vCenter Server and vCenter Single
Sign-On are on the same virtual machine or physical server, you can designate the local operating system
group Administrators as vCenter Server administrative users. This option is the default. This behavior is
unchanged from vCenter Server 5.0.
For larger installations, where vCenter Single Sign-On is part of the Platform Services Controller and
vCenter Server are deployed on dierent virtual machines or physical servers, you cannot preserve the same
behavior as in vCenter Server 5.0. Instead, assign the vCenter Server administrator role to a user or group
from an identity source that is registered in the vCenter Single Sign-On server: Active Directory, OpenLDAP,
or the system identity source.
