屬性值
A TimeSpan object that specifies the work item timeout.
備註
This property is optional and has a default value of 15 minutes.
A work item consists of notifications within a single batch that are delivered through the same delivery channel. Notification Services divides notification batches into work items to take advantage of batch processing and to deliver notifications by using multiple delivery channels in parallel.
When a distributor thread is free, it picks up an available work item to format and deliver. The WorkItemTimeout value configures a time limit for formatting and delivery of the notifications in that work item. If the distributor exceeds the timeout, it returns the work item to the pool of available work items so it can be processed by another distributor thread, assuming there is a retry schedule.
範例
The following examples show how to define execution settings for a delivery protocol:
smtpProtocol.FailuresBeforeEventLog = 2;
smtpProtocol.FailureEventLogInterval = new TimeSpan(0, 10, 0);
smtpProtocol.FailuresBeforeAbort = 10;
smtpProtocol.MulticastRecipientLimit = 50;
smtpProtocol.WorkItemTimeout = new TimeSpan(0, 20, 0);
smtpProtocol.FailuresBeforeEventLog = 2
smtpProtocol.FailureEventLogInterval = New TimeSpan(0, 10, 0)
smtpProtocol.FailuresBeforeAbort = 10
smtpProtocol.MulticastRecipientLimit = 50
smtpProtocol.WorkItemTimeout = New TimeSpan(0, 20, 0)
