3 Sending and Receiving Alerts

You can either send Enterprise Manager alerts to MOM in real-time, or you can forward MOM events to Enterprise Manager as explained in the following sections:

• Sending Enterprise Manager Alerts to MOM

• Receiving MOM Alerts in Enterprise Manager

Sending Enterprise Manager Alerts to MOM

You can send Enterprise Manager alerts to MOM in real-time. You can also choose which type of alerts to send, such as critical alerts on a production database. Additionally, Enterprise Manager 10g Release 4 supports metric alerts.

Prerequisites

To send alerts, MOM needs to support the following:

• "createEvent" and "updateEvent" literal-document style Web services, as described in the section "Providing Deployment Descriptor Mappings" in the Oracle Enterprise Manager Connectors Integration Guide.

• IP-based or SOAP header-based authentication. For more information, see the "Building a Help Desk Connector" chapter in the Oracle Enterprise Manager Connectors Integration Guide.

Configuring Rules to Send Alerts

You need to configure rules for sending out alerts through the MOM connector as follows:

1. From the Grid Control console, click Preferences in the upper right corner. The General Preferences page appears.

2. In the menu at the left, click My Rules. The My Notification Rules page appears.

3. Select a rule, then click Edit. The Edit Notification Rule page appears.

4. Select the Methods sub-tab. The E-mail Notification page appears.

5. Select the Microsoft Operations Manager Connector advanced notification method, then click OK.

6. Repeat this process for each rule you want to set.

Migrating from 10.2.0.3 to 10.2.0.4

If you have already configured the MOM Connector in version 10.2.0.3 and want to upgrade to version 10.2.0.4, do the following to enable bi-directional capability:

1. From the Grid Control console, click Setup in the upper right corner. The Overview of Setup page appears.

2. In the menu at the left, click Management Connectors. The Management Connectors page appears.

3. Select Microsoft Operations Manager Connector, then click the Configure icon. The Configure Management Connector page for MOM appears.

4. Click OK. No other action is needed to enable bi-directional capability.

Receiving MOM Alerts in Enterprise Manager

The MOM Connector also enables you to forward MOM events to Enterprise Manager, thereby enabling better correlation of IT problems across the technology stack. You can specify when and how alerts should be triggered by configuring event rules in the Microsoft Operations Manager console. When an alert is raised, it is assigned a default resolution state that you specify. The MOM Connector creates a new resolution state specifically for the purpose of sending it across to Enterprise Manager.

Prerequisites

MOM needs to support the following literal-document style Web services:

• "getNewAlerts"

• "getUpdatedAlerts"

• "acknowledgeAlerts"

• "updateAlerts"

Forwarding Alerts to Enterprise Manager

You can forward MOM alerts to Enterprise Manager automatically or manually as follows:

• Automatically forward alerts by specifying the connector resolution state in the event rules and alert rules.

• Manually forward any existing MOM event to Enterprise Manager by changing the resolution state of the alert.

Refer to the Microsoft Operations Manager guide for more details.

Figure 3–1 shows alerts in the Operator Console of Microsoft Operations Manager. The first alert has a Resolution State set to MOM Connector, which indicates that the alert is waiting to be forwarded to Enterprise Manager. When the polling job picks up the alert and forwards it to Enterprise Manager, the alert's resolution state returns to its original state.

How Enterprise Manager Responds

After the alerts have been forwarded to Enterprise Manager, they are associated with the appropriate targets, depending on the mapping option(s) you select. The MOM Connector keeps track of all the events forwarded from MOM, and automatically updates information in Enterprise Manager after changes in MOM occur. This ensures that the two systems are always synchronized, providing you with timely information about your Microsoft environment.
