Applies to all AMB transaction types: message send and message receive.\n\n-   **Reference Completer**\n\n    Stops the reference completer transaction after five seconds.\n\n-   **REST Aggregate API request timeout**\n\n    Prevents inbound REST Aggregate API transactions from running for longer than 60 seconds.\n\n-   **Homepage Widgets**\n\n    Prevents all homepage widgets from running longer than 30 seconds.\n\n-   **REST Attachment API request timeout**\n\n    Prevents inbound REST Import Set API transactions from running for longer than 60 seconds.\n\n-   **UA Count Persistor Quota**\n\n    Prevents UA count persistor scheduled jobs from running for more than one hour.\n\n-   **UI Transactions**\n\n    Cancels UI transactions that are two seconds away from the 5-minute server disconnect. ServiceNow datacenter load balancers display an internal server error \\(HTTP Error 500\\) to users after five minutes. This quota rule returns a transaction canceled page instead of an error. This rule includes an exception to prevent the cancellation of background scripts.\n\n-   **PA Diagnostics All**\n\n    Prevents any Diagnostics transaction that originates outside the scope of the Diagnostics application from running longer than 30 minutes. Diagnostics transactions refer to executing a diagnostic, opening a Diagnostics form, or opening a Diagnostics list.\n\n\n## Normal transaction activities\n\nBefore 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](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/platform-administration/platform-performance/t_ViewAndKillAnActiveTransaction.md) if necessary. Over time, you can determine the normal transaction load for your instance and set your quotas to match these norms.\n\n**Parent Topic:**[Platform performance reference](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/platform-administration/platform-performance/platform-performance-references.md)\n\n"}}
