Various transaction quota rules are available in the base system.

Fix Script Processor
:   Allows the fix script processor to run for four hours.

Presence
:   Cancels presence requests quickly when the system is busy.

REST Import Set API request timeout
:   Prevents inbound REST Import Set API transactions from running for longer than 60
    seconds.

REST Table API request timeout
:   Prevents inbound REST Table API transactions from running for longer than 60 seconds.

AMB Transactions
:   Cancels AMB transactions lasting longer than the specified maximum duration. Applies to all
    AMB transaction types: message send and message receive.

Reference Completer
:   Stops the reference completer transaction after five seconds.

REST Aggregate API request timeout
:   Prevents inbound REST Aggregate API transactions from running for longer than 60
    seconds.

Homepage Widgets
:   Prevents all homepage widgets from running longer than 30 seconds.

REST Attachment API request timeout
:   Prevents inbound REST Import Set API transactions from running for longer than 60
    seconds.

UA Count Persistor Quota
:   Prevents UA count persistor scheduled jobs from running for more than one hour.

UI Transactions
:   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.

PA Diagnostics All
:   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.

## Normal transaction activities

Before setting transaction quotas, navigate to User AdministrationActive Transactions to review the normal transaction activities for your instance. You can [view and terminate long-running transactions](https://servicenow-prod.fluidtopics.net/3ptRU7fyrtO2iYChxGRBEA "Administrators can view active transactions and kill 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.
