Normal transaction activities

Before setting transaction quotas, navigate to User Administration > Active Transactions to review the normal transaction activities for your instance. You can view and terminate long-running transactions if necessary. Over time, you can determine the normal transaction load for your instance and set your quotas to match these norms.
