In Microsoft Operations Manager (MOM) 2005, when you put a MOM agent in maintenance mode, responses may not immediately stop running on the Management Server. The responses continue running for up to five minutes. Additionally, when you remove an agent from maintenance mode, responses may not immediately start running on the Management Server. The responses do not start running for up to five minutes.

This article describes how to avoid these delays.

Note These delays depend on the rule change poll interval. If you have changed the rule change poll interval, the delays may be significantly longer than five minutes.

When you use the MOM Operator console to put a MOM agent in maintenance mode, alerts are immediately autoresolved. However, there may be a delay of up to ten minutes before responses stop running for that agent. To immediately stop responses, follow these steps:

1. Start the MOM 2005 Administrator console.
2. Right-click Management Packs, and then click Commit Configuration Change.

When you remove a MOM agent from maintenance mode, alerts immediately stop being autoresolved. However, responses may not start running for up to five minutes. To immediately start responses, follow these steps:

1. Start Microsoft SQL Server Enterprise Manager.
2. Expand Microsoft SQL Servers, expand SQL Server Group, and then expand the SQL server for MOM.
3. Expand Management, expand SQL Server Agent, and then click Jobs.
4. Right-click the OnePoint - Computer Maintenance job, and then click Start Job.

To adjust the delay that a MOM agent experiences when you put the agent in maintenance mode, follow these steps:

1. Start the MOM 2005 Administrator console.
2. Expand Administration, and then expand Global Settings.
3. In the right pane, double-click Management Servers.
4. Click Rule Change Polling tab in the Management Servers Properties dialog box.
5. In the Rule change poll interval box, set an interval to scan for rule changes.

Note You can adjust the delay that a MOM agent experiences when you remove the agent from maintenance mode. To do this, modify the schedule of the OnePoint - Computer Maintenance job that runs in SQL Server. However, we do not recommend that you change this schedule.
