Purpose

The notification methods define the method by which the notifications will be sent to the EM administrators. The available Notification methods in EM are :

Email Notification
SNMP Trap
PL/SQL Procedure
OS Command

This document describes the steps involved in configuring the Email Notification Method available in EM.

It is also necessary to define a Notification Rule. The Notification Rule provides an option to choose the targets and conditions under which the OMS should be sending notifications.

The Notification Rules can be configured with the severities/violations of metrics/policies and various states of the Jobs for which the notification has to be sent for.  

Scope

This document is applicable to EM administrators who wish to recieve Email notifications from EM, whenever critical/warning alerts are raised for any of the targets.

Details

Email Notification Method

The notification will be via an Email, sent to the email address specified for the EM administrator. This will require notification rules and schedule to be configured as well.

The notification schedule controls 'who' will be notified using the email notification when the notification rule is satisfied i.e. this will have the email address(es) to which the notification will be sent.

Configuring Email Notification Method  

- Go to Setup -> Notification Methods.

- Enter the 'Outgoing Mail (SMTP) Server' hostname or IP address. For ex : smtp.domain.com.

a) If the SMTP server is running on the default port : 25, then there is no need to specify the port.
Else the port number has to be specified in the form : smtp.domain.com:100

b) You can also specify multiple SMTP servers/gateways here in this manner : smtp1.domain.com, smtp2.domain.com:100

c) Defining multiple e-mail servers will improve the reliability of e-mail notification delivery and spread the load across multiple systems. The Management Service makes use of each server/gateway to send e-mails and the behavior is controlled by the following parameters in the /sysman/config/emoms.properties file :

The above mentioned values are the default ones and can be modified if necessary. 

NOTE for 11g use emctl set property to change emoms properties.

- If the Mail server requires a username/password, then specify them under 'User Name' and 'Password' fields. Leave these blank, if no authentication is required.
(Refer to troubleshooting Step 3, below).

- Enter the identification string under 'Identify Sender As' field, so that these emails can be distinguished from other emails and recognized to be sent from EM.

- Ensure that a valid Email ID is entered for the "Sender's E-mail Address".

The e-mail address you specify on this page is not the e-mail address to which the notification is sent. You will have to specify the e-mail address (where notifications will be sent) from the Preferences General page.
- Click on 'Apply' to save the changes.

- When you click on 'Test Mail Servers', a test mail is sent to the Email Id specified for 'Sender's E-mail Address' with the following :

- The Email notification method is now ready for usage. You can choose this method when configuring the notification rules.

Note:

- Only a Super-Administrator user can configure SMTP servers.
- The Notification Schedule is used only by Email Notification Method.
- Any e-mail delivery problems, in the future, will be automatically sent to the Sender's E-mail Address.
- It is possible to customize the content sent in an Email notification from the 10.2.0.5 Grid Control version onwards.

Note 813399.1 New Features for Notifications in 10.2.0.5 Enterprise Manager Grid Control

Important : Ensure that the "E-mail addresses" and the Notification Schedule are correctly specified, and that the notification schedule has been correctly scheduled using that note :

Troubleshooting

1. If you get any connectivity errors after clicking on 'Test Mail Servers', follow the steps in the following documents to test the connectivity to the SMTP server, from the OMS machine :

2. After clicking on the 'Test Mail Servers', if there are errors like :

Ensure that the Sender's Email ID is specified correctly.

3. The SMTP server authentication option does not work fine upto 10.2.0.3 GC version.
This includes authentication types such as Login, Plain, Digest-MD5, NTLM etc.

Bug 5654494 :Abstract: OUTGOING MAIL (SMTP) SERVER CONNECTING ERROR

This is an unpublished bug. Refer to the details in :

Note 429836.1 : Grid Control and SMTP authentication

This has been fixed in the 10.2.0.4 GC release.

4.  Till 10.2.0.4 Grid Control, if the SMTP server being used is SSL enabled, the test mesage will fail.

10.2.0.5+ Grid Control supports SSL / TLS communication to the SMTP server.
