You can configure the maximum number of database connections that can occur simultaneously. To limit the growth of the vCenter Server database and save storage space, you can configure the database to discard information about tasks or events periodically.
Do not use the database retention options if you want to keep a complete history of tasks and events for your vCenter Server.
- In the vSphere Web Client, navigate to the vCenter Server instance.
- Select the Configure tab.
- Under Settings, select General.
- Click Edit.
- Select Database.
- In Maximum connections, type a number.
Increase this number if your vCenter Server system performs many operations frequently and performance is critical. Decrease this number if the database is shared and connections to the database are costly. Do not change this value unless one of these issues pertains to your system.
- Select the Enabled check box next to Task cleanup to have vCenter Server periodically delete the retained tasks.
- (Optional) In Tasks retained for, type a value in days.
Information about tasks that are performed on this vCenter Server system is discarded after the specified number of days.
- Select the Enabled check box next to Event cleanup to have vCenter Server periodically clean up the retained events.
- (Optional) In Events retention, type a value in days.
Information about events for this vCenter Server system is discarded after the specified number of days.
- Click OK.
