Prioritizing Email Sending Daemon Jobs

In Siebel Marketing, the priority level that you specify for a campaign also determines the priority that is assigned to email jobs associated with the campaign. As a result, email jobs for critical campaigns are executed before jobs for less critical campaigns. The priority levels that can be chosen for a campaign and, therefore, for associated email jobs are: 1-Urgent, 2-High, 3-Medium, or 4-Low.

In general, the Email Sending Daemon suspends processing of a lower priority job if a higher priority job enters the processing queue. However, in some circumstances, it is more efficient to continue processing the lower priority job, for example, if the low-priority email job has only a few recipients and the high-priority job has thousands.

To accommodate these circumstances, you can determine a priority threshold for email jobs. The priority threshold is the number of recipients that an email job must have in order that its priority level is always maintained. For example, if you specify a value of 50, then email jobs with fewer than 50 recipients are always assigned a priority of High by the Email Sending Daemon, even if the priority initially specified for the campaign is 3-Medium, or 4-Low.

The following procedure describes how to set the priority threshold for Email Sending Daemon jobs.

To set the priority threshold for Email Sending Daemon jobs

1. Navigate to the esd.properties file in the ESD_root installation directory.
2. Open the esd.properties file in a text editor.
3. Set the value of the esd.priorityThreshold parameter to an appropriate value.

   The default value is 5001, indicating that the priority assigned to any email job with more than 5001 recipients is not to be overridden by the Email Sending Daemon.
