Enterprise Manager uses e-mail addresses to send notifications.
You can use multiple addresses if you want to be notified in different ways.
You can also specify the format for these e-mails. You have to define a notification
schedule before any e-mail notifications can be sent.
You need to set up your notification schedule in order to receive e-mail notifications.
You can use the Notification Schedule page to select a user for which a notification
schedule needs to be set. You must define an e-mail address for the administrator
before defining a notification schedule. You can specify the e-mail address
for each day in the schedule.
You learn to set the preferred credentials for the targets. Preferred credentials
can be used to simplify access to targets that you manage. After you set the
preferred credentials for a target, the applications that log in to that target
will automatically use the preferred credentials.
In this tutorial, you learn to create an e-mail address, define
a schedule, and define preferred credentials.

Joe has a multiple pager he uses for work. He needs to make
sure EM alerts are sent to it when he's on duty.
In addition to this, Joe has a rotating schedule where every
third week, he works late on Wednesday and Friday.
Database administrators need to provide database-level credentials
to be able to monitor performance or perform any administrative action through
Grid Control. By setting up preferred credentials, they will be able to quickly
access these areas without reentering their credentials. Also, the Oracle Enterprise
Manager job system can pull up these credentials for scripts or jobs that run
against these targets.

Specify the e-mail addresses and message formats you want
associated with your Enterprise Manager account. All e-mail notifications you
receive from Enterprise Manager will be sent to the e-mail addresses you specify.
For example,home@oracle.com, work@oracle.com, pager@oracle.com, and so on.
Specify the message format to be used with each e-mail
address. You can choose either Long or Short formats.
In this section, you learn how to configure your e-mail preferences
for notifications.
Perform the following steps to create
an e-mail address:
|
1.
|
Open the browser and enter the
URL to access the server on which you installed the management service,
in the following format:
http://<management
service hostname>.<domain>:<port>/em/
The default port value on a machine with no other instances
installed on it is 7777. However, if there are other instances running
on the machine, then the port may be different.
The Login page will be displayed. Enter the User Name
and Password, and then click the Login button.

Use the Home page of the Enterprise Manager Grid Control to get
a high-level view of your entire enterprise.
This page is useful as a starting point when you are assessing the health
of your Oracle environment. It provides high-level data, as well as the
ability to drill down so you can investigate, isolate, and repair availability
and performance problems.
First, to create an e-mail account, from the Grid Control home page,
click Preferences.
|
| 3. |
To add an e-mail account, click the Add Another Row button.
|
| 4. |
Specify the e-mail address in the text field. From Message Format, you
can choose the format in which you want to receive the mail. You can choose
either the long format or the short format. In the long format, you see
the severity, the target name, and the message. In the short format, you
see only the severity and the target name. Choose Long Format.
|
| 5. |
You can add another e-mail address here. Click Apply to save the
changes.
|
| 6. |
You have successfully saved your e-mail address for the notification
to be sent to.

Back to Topic List
A notification schedule is a rotating schedule used by Enterprise
Manager to determine how to send e-mail notifications to administrators. Each
administrator has exactly one notification schedule. When an alert needs to
be e-mailed to an administrator, Enterprise Manager consults that administrator's
notification schedule to determine the e-mail address to be used.
In a notification schedule, an administrator can specify different
e-mail addresses based on day of the week and time of the day. When sending
e-mail notifications, Enterprise Manager will use the e-mail addresses appropriate
for that day and time. Time periods that are left empty signify periods where
no e-mail notifications should be sent. A notification schedule repeats every
interval specified in the notification schedule definition.
You can use the Notification Schedule page to select a user
for which a notification schedule needs to be set. For each day in the schedule,
you need to specify the e-mail addresses that should be used to send you e-mail
notifications. Therefore, an e-mail address must be defined for the administrator
before defining a notification schedule. You can use the General page for more
information about defining e-mail addresses for an administrator. For each administrator
for whom a notification schedule has been specified, all specifics pertaining
to his or her schedule are displayed.
Note: Other super administrators cannot change super
administrator SYSMAN's notification schedule. If no notification has been set
for an administrator, this page will be blank.
After a notification schedule has been defined, you can click individual notification
instances in the notification schedule table to view information specific to
that notification instance.
Perform the following steps to define a schedule:
|
1.
|
Click the Preferences link. From the left navigation
pane, click the Schedule link.
|
|
2.
|
Click the Define Schedule button to define a
notification schedule.
|
|
3.
|
As per the scenario, you have to create a notification
schedule every third week. On the Edit Schedule Definition page, you can
specify the time schedule for which an e-mail notification has to be sent.
From the Rotation Frequency drop-down list, select 3 Weeks.
|
|
4.
|
You can select the time zone too. Here, select the US Pacific Time.
|
| 5. |
Click Continue.
|
|
6.
|
Specify the Start Date and End Date. Your notification schedule is a
rotating schedule that repeats based on the frequency you specify. It
will take effect immediately or can be deferred to a later start date.
No notifications will be sent before the start date.
You can click the flashlight icon to add e-mail addresses.
Because the notification has to be send every third week on Wednesday
and Friday, select Wednesday and Friday from Days of Week.
In Weeks, select Week 3. Specify the e-mail address to which you
want to send the notification. Click Batch Fill-in.
|
| 7. |
From the View drop-down list, select Week 3. You can see
that the notification has been scheduled on Wednesday and Friday.
|
| 8. |
Click Finish to create the notification.

Preferred credentials simplify access to managed targets by
storing target login credentials in the Management Repository. With preferred
credentials set, users can access an Enterprise Manager target that recognizes
those credentials without being prompted to log in to the target. Preferred
credentials are set on a per user basis, thus ensuring the security of the managed
enterprise environment.
You can set preferred credentials for the following target
types:
 Hosts
Databases
Clusters
Cluster Databases (RAC
databases)
Application Servers
The Preferred Credentials page provides a top-level view of
all preferred credentials set for your Enterprise Manager environment. On this
page, you can set preferred credentials for any managed target listed in the
Preferred Credentials table. Each row of the table provides a credential summary
for each target. Targets are organized according to target type.
Perform the following steps to define preferred credentials:
| 1. |
Click the Preferences link.
|
| 2. |
You can use preferred credentials to simplify access to targets that
you manage. If a target has preferred credentials set, applications that
log in to that target will automatically use the preferred credentials.
From the left navigation pane, click Preferred Credentials.
|
| 3. |
The Preferred Credentials page provides a top-level
view of all preferred credentials set for your Enterprise Manager environment.
On this page, you can set preferred credentials for any managed target
listed in the Preferred Credentials table. Targets are organized according
to target type. You see the following columns:
Target Type: Displays
category of target type
Total Targets: Displays
the total number of monitored targets of a particular type
Targets with Credentials
Set: Displays number of targets that have explicit preferred credentials
Default Credentials
Set: Displays number of targets of the target type that have the default
preferred credentials set
Set Credentials:
You can change the preferred credentials by clicking this icon.
|
| 4. |
As per the scenario, you need to specify the preferred credentials for
the database instance. Scroll down to the target type Database Instances.
Click the icon in the Set Credentials column.
|
| 5. |
The Database Preferred Credentials page is displayed. In the Target Credentials
section, specify the credentials for the database and the host. This credential
will override the Default Credentials. Explicit preferred credentials
are set at the user level. This eliminates possible security concerns.
|
| 6. |
Click Test to verify the target credentials against the database. It
will test the database credential using both the Normal and SYSDBA credentials.
Here, you do not need to specify the SYSDBA credentials. It also tests
the host credentials.
|
| 7. |
You can see that the credentials were successfully verified.
|
| 8. |
Click the Apply button to save the changes.
|
| 9. |
You have successfully saved the preferred credentials.
