WHAT IS ENTERPRISE MANAGER CLOUD CONTROL?

▸ Enterprise Manager Cloud Control provides a centralized monitoring and management platform for IT infrastructure.

▸ Enterprise Manager can manage and monitor various targets (host, ASM, RAC, Database, Listener, Weblogic, Tomcat, Apache and more), and it’s possible to add more target types using plugins.

5


ENTERPRISE MANAGER CLOUD CONTROL ARCHITECTURE

▸ Agents: Collect monitoring and configuration data from the targets and executes tasks

▸ Management Server (OMS): Receives and processes data from Agents, Provides UI and Target Specific Management

▸ Repository (OMR): Persistent store for data collected from the managed TargetsNotifications

SOFTWARE LIBRARY

Filesystem repository used to store software entities such as:

▸ Software patches

▸ Virtual appliance images

▸ Gold images

▸ Application software

▸ Deployment procedures

CONSOLE AND EM CLI

▸ Console: Rich, customisableapplication accessed throughweb browser. Primary interface for interactive management of targets.

INCIDENT CREATED NOTIFICATION

tablespace usage %75 warning%90 critical


MONITORING AND INCIDENT HANDLING

▸ Create a copy of the system default Incident Rule Sets. The default rule sets are locked.

▸ Create monitoring templates, set critical metric values.

▸ Create groups. Assign monitoring templates to groups and set different notification types based on groups.

▸ Update all notification so only critical alerting is performed*. You use the EM Console to view non-critical warnings

18


INCIDENT DASHBOARD

NEW ON EM13C

19


CORRECTIVE ACTIONS

▸ Automate routine administrative tasks to resolve common incidents

▸ Create a corrective action (OS command, SQL, RMAN Script or EM actions such as start/stop agent)

▸ Assign the corrective action to a metric alert (on a monitoring template)

▸ Apply the monitoring template to the targets

20


DATABASE PROVISIONING

Repeatable, reliable, automated, unattended deployment procedures for creating, cloning, updating databases

DEPLOY AGENTS (ADD HOST TARGETS)First deploy agents to hosts to convert them managed hosts, then add targets running on the host (ASM, Listener, Database)

38

HOW TO BACKUP

BACKUPS

You need to back up following components:

▸ The Oracle Management Service: Filesystem backup of installed software* and backup of OMS configuration:

$OMS_HOME/bin/emctl exportconfig oms

▸ The Management Repository: Backups can be taken using RMAN

▸ The software library: Taking file system backups daily is sufficient in most cases.
