Database Reference
In-Depth Information
This console interface allows the user to view the service status, incidents, violations, performance charts, test
performance, configuration topology of the job environment, and all other features included in the EM Job System.
You also can locate the EM Jobs Service page (and see how wildcard searches work in EM12c) by clicking
Targets
➤
All Targets, typing
%job%
in the Search Target Name box, and clicking the arrow. The agent EM Jobs
Service shows in the list and can be accessed by clicking the target name.

Wildcard searches are easy in the All Targets view
Monitoring Configuration
The EM Jobs Service interface includes various tabs that provide access to the Job System's functionality. The tab that
is perhaps the most frequently used by DBAs is the Monitoring Configuration tab (see Figure
11-5
).
Figure 11-5.
The Monitoring Configuration tab is one of the most used in the EM Jobs Service interface
The Monitoring Configuration section of the user interface contains numerous options to interact with features of
the EM Jobs Service.
The Root Cause Analysis Configuration option can be used to perform automatic or manual inspection of any EM
service upon failure. This analysis can then pinpoint the issue or be uploaded to My Oracle Support to assist with a
service request. This feature is very beneficial in saving the administrator time otherwise wasted when manually filling
out a service request in the My Oracle Support interface. The service requests covered in this section are for the main
EM12c services, including the Enterprise Manager console, the Oracle Management Service, and the EM Jobs Service.
The Performance Metrics link enables you to configure thresholds for EM job-step throughput and job-step
backlog. When using the EM Job System as the main job scheduler for a database environment, this can offer
a monitoring incentive that is missing from most other job schedulers. Gathering postexecution performance
information may not be available in other scheduling/logging methods, but with the EM12c Jobs Service, all data is
retained for a default of 31 days.
Another link within the Monitoring Configuration tab, is Service Tests and Beacons. Service tests are an excellent
way to test the ability of a web page to complete a simple transaction on a regular interval, to test for uptime, or to log
in to a web site and verify that files are available for download at a certain time. Unlike metric extensions (described in
Chapter 13), this feature is very URL specific and uses an EM Job to fulfill the task on the requested interval.
This feature has the unique option to record a web session by using an ActiveX plug-in that is then configured
as part of an EM job to perform the task during the scheduled interval, checking for successful completion of the
recorded steps a user would complete if they were to access the same web site. Figure
11-6
shows a session recording
from the web site— successfully signing in, accessing four files, and then signing out. This session will be used by the
EM Jobs Service to create the performance test and then continue on to the beacon settings.
