Motivation
■ As an Enterprise Manager administrator you are responsible
of a wide variety of tasks including:
▪ Discovery and maintenance of targets
▪ Deploy plug-ins
▪ Tune OEM 12c performance
▪ Maintain backups
▪ Others (Cloud, Self-Service, Alerts, etc.)
■ With such time consuming tasks, administrators need to find
the most efficient ways to manage the manager.
▪ Best practices
▪ Task automation
▪ Command Line EMCLI

Agenda
■ Lifecycle Management
▪ EMCLI to deploy multiple Plug-ins at once
▪ Apply OMS, Plug-in and Agent patches during the same
maintenance window
▪ Mass Agent Deployment
■ Target Monitoring
▪ Monitoring Templates
▪ Alerts Report
▪ Administration Groups
■ Security
▪ Secure your SYSMAN schema account
▪ Secure and lock the OMS and Agents
▪ Use EMCLI to configure OEM Audit system

Lifecycle Management
■ Use EMCLI to deploy multiple plug-ins at once - OMS

■ Use EMCLI to deploy multiple plug-ins at once - OMS
▪ deploy_plugin_on_server
— Deploys a plug-in on the Management Servers. The deployment
process for some plug-ins might restart the Management Servers. If
the plug-in is already deployed on one of the servers, this server is
skipped. If a lower version of the plug-in is already deployed, the
plug-in is upgraded. If a lower revision of the plug-in is already
deployed, the new revision is applied.
emcli deploy_plugin_on_server
-plugin="oracle.sysman.db:12.1.0.5.0;oracle.
sysman.emas.oms.plugin_12.1.0.5“
-sys_password=<sys_password>
-use_last_prereq_result

■ Use EMCLI to deploy multiple plug-ins at once – OMS
$emcli deploy_plugin_on_server -
plugin="oracle.sysman.db;oracle.sysman.emas"
-prereq_check
Performing pre-requisites check... This will take a while.
Oracle recommends that you take a backup of the
repository, and export the first management server
configuration using the command "emctl exportconfig
oms". Otherwise ensure that appropriate recovery plan is
in place prior to deploying the plug-in.
Retry plug-in deployment once you have backed up the
repository and configuration of first management server.
Use the option "-repo_backup_taken" to confirm that
these have been backed up.

■ Use EMCLI to deploy multiple plug-ins at once – OMS
■ Savings around 91 minutes

■ Use EMCLI to deploy multiple plug-ins at once - Agent
▪ deploy_plugin_on_agent
— Deploys a plug-in on Management Agents. Agent names must be
provided for plug-in deployment.
emcli deploy_plugin_on_agent
-plugin=" oracle.sysman.db:12.1.0.5.0;
oracle.sysman.emas.oms.plugin_12.1.0.5.0"
-agent_names="myhost1.example.com:1838;
myhost2.example.com:1838"

■ Apply OMS, Plug-in and Agent patches during the same
maintenance window
▪ I suggest to perform monthly maintenance on the OMS’s
▪ Test all patches and plug-ins on your QA environment first
▪ Always verify if your OPatch is up to date
▪ Always shutdown JVMD and APD before applying a patch
▪ Try to apply all the required changes on the same window
— Deploy new plug-ins (use emcli)
— Apply OMS patches (PSU’s & patches)
— Apply plug-in patches
— Apply patches to your standby OMS
▪ Agent patching can be done while OMS’s is up, but don’t forget
to patch the agents as well!

■ Perform Mass Agent Deployment

▪ Fresh Install
— Installs the vanilla version of the agent.
▪ Clone Existing Agent
— Installs an agent using an existing source agent that is well tested
and patched.
▪ Add Host to Shared Agent
— Installs an agent using an existing master agent that is installed on a
NFS mounted drive.

emcli submit_add_host –host_names=<host_list>

installation_base_directory=<installation_base_
directory> -

credential_owner=<credential_owner>]
[-wait_for_completion] [-
source_agent=<clone_source_agent_name>] [-
master_agent=<master_agent_name>]
[ ] indicates that the parameter is optional

Monitoring Templates
■ Group of metrics and their thresholds for a particular target
type

Administration Groups – Target Properties

Administration Groups
$ emcli login -username=sysman
Enter password :
Login successful
$ emcli set_target_property_value
-property_records="Development DB:composite:LifeCycle Status:Development"
-propagate_to_members
Properties updated successfully
$ emcli logout
Logout successful

Secure your SYSMAN account
■ SYSMAN is the schema owner, as a result is more privileged that a
Super Administrator.
■ Users and Administrators should login using their own accounts,
this is helpful while auditing operations.
■ There’s a method to disable SYSMAN access from the console and
emcli. DB access and “emctl status oms –details” still work.
SQL> UPDATE MGMT_CREATED_USERS
SET SYSTEM_USER='-1'
WHERE user_name='SYSMAN';

Set it to 1 to re-enable it

Secure and Lock OMS and Agents
■ Is recommended that all communications between OMS, agents,
repository and users is made by secure mode (HTTPS).
■ In secure mode, HTTP port is locked.
■ Secure mode is enabled by default, but upgrade does not secure-
lock the OMS.
■ Agents should be secured in order to make use of HTTPS port.
■ Agents not secured, will not be able to communicate with a secured
OMS.

■ Not secured OMS

Use EMCLI to configure OEM Audit system
■ Basic OEM audit is enabled by default.
■ Whenever a user login-logout, the action is audited.
■ More default audit operations include:
▪ Apply Update
▪ Change MGMT_VIEW User Password
▪ Change Repository Password
▪ Configure Authentication
▪ Copy EM Key to Repository
▪ Remove EM Key from Repository
▪ Create Custom CA
▪ Remove Update
▪ Secure Console
▪ Secure Lock
▪ Secure OMS

■ You can configure the Enterprise Manager Audit System by using
the following EM CLI commands:
▪ enable_audit: Enables auditing for all user operations.
▪ disable_audit: Disables auditing for all user operations.
▪ show_operations_list: Shows a list of the user operations being
audited.
▪ show_audit_settings: Shows the audit status, operation list,
externalization service details, and purge period details.
▪ update_audit_settings: Updates the current audit settings in the
repository.

■ The update_audit_settings command updates the current audit
settings in the repository and restarts the Management Service.
emcli update_audit_settings -
audit_switch="ENABLE/DISABLE" -
operations_to_enable="name of the operations to
enable, for all oprtations use ALL" -
operations_to_disable="name of the operations to
disable, for all oprtations use ALL" -
externalization_switch="ENABLE/DISABLE" -
directory_name="directory_name (DB Directory)" -
file_prefix="file_prefix" -file_size="file_size
(Bytes)" -
data_retention_period="data_retention_period
(Days)"

▪ -audit_switch: Enables auditing across Enterprise Manager. The
possible values are ENABLE/DISABLE. Default value is DISABLE.
▪ -operations_to_enable: Enables auditing for specified operations.
Enter All to enable all operations.
▪ -operations_to_disable: Disables auditing for specified operations.
Enter All to disable all operations.
▪ -externalization_switch: Enables the audit data export service. The
possible values are ENABLE/DISABLE. Default value is DISABLE.
▪ -directory: The database directory that is mapped to the OS directory
where the export service archives the audit data files.

▪ -file_prefix: The file prefix to be used by the export service to create the
file in which audit data is to be stored.
▪ -file_size: The size of the file on which the audit data is to be stored.
The default value is 5000000 bytes.
▪ data_retention_period: The period for which the audit data is to be
retained inside the repository. The default value is 365 days.
