Notification Methods allow you to define different mechanisms for sending notifications. These include e-mail, SNMP traps, Java callbacks, running custom scripts, or all four. Once defined, these methods can then be used with Notification Rules for sending notifications to administrators as a result of alert occurrences.
Through the Notification Methods page, you can
set up the outgoing mail servers if you plan to send e-mail notifications through notification rules
manage (create, edit, or delete) scripts and SNMP traps
Before Enterprise Manager can send e-mail notifications using Notification Rules, you must first set up the Outgoing Mail (SMTP) servers.
Note: Only a privileged user can configure SMTP servers.
Specify one or more outgoing mail (SMTP) server names, the name you want to appear as the sender of the notification messages, and the e-mail address you want to use to send your e-mail notifications. The Sender's Mail Address must be a valid address on each gateway that you specify. This e-mail address will be notified by the mail server of any problem encountered during the sending of an e-mail notification.
For example,
Outgoing Mail (SMTP Server) smtp01.oracle.com, smtp02.oracle.com
Identify Sender As EM Notifications
Sender's Mail Address mgmt_rep@oracle.com
Note: 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. For information on specifying e-mail addresses for e-mail notification, see Specifying E-mail address for E-mail Notifications.
Defining multiple e-mail gateways will improve the reliability of e-mail notification delivery and spread the load across multiple systems. The Management Service makes use of each gateway to send e-mails and the behavior is controlled by the following parameters:
# The maximum number of e-mails that can be sent in a single connection to an
# e-mail server
# em.notification.e-mails_per_connection=20
#
# The maximum number of e-mails that can be sent in a minute
# em.notification.e-mails_per_minute=250Based on the defaults above, the first gateway is used to send 20 e-mails before the Management Service switches to the next gateway which is used to send another 20 e-mails before switching to the next gateway. This prevents one gateway from becoming overloaded and should improve overall reliability and throughput.
Clicking the Test button will result in a test e-mail being sent to the Sender's Mail Address. You should verify that the e-mail was received to ensure the test completed successfully.
Before Enterprise Manager can send notifications through Java callbacks, OS scripts, PLSQL procedures, or SNMP traps, you need to first define them. Any administrator can then use these methods in Notification Rules.
Within the Scripts and SNMP Traps section, choose to add a method from the pull down list and click Go.
You can choose from the following.
OS Command
PLSQL Procedure
SNMP Trap
Create the method by filling in the fields.
Note: Creation of Java callbacks is not supported in this release.
Remember to create Notification Rules in order to send notifications through these methods.
