Change Default Configuration Values for Triggers

The default message body value is the size of the buffer that the Message Queuing Triggers service allocates for an incoming message. It is best to set this value equal to a size that will accommodate 90 percent of all messages that are expected to arrive in monitored queues. If you set this value too small, it forces the service to reallocate these buffers for every message. If you set it too large, an excessive amount of memory is allocated.

Changing default configuration values for triggers

To change default configuration values for triggers

  1. Open Computer Management.

    Where?
