By default, a vCenter Server creates a maximum of 50 simultaneous database connections. If you configure 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 setting of 50. If you configure 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 reconfigure the nondefault setting.
About this task
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 configure the authentication for your database. For more information about configuring authentication, see the documentation for your database.
