New Features - Plug-ins

In earlier releases, plug-ins were meant to embed

third party Target-Types in Enterprise Manager

With EM12c

Plug-ins are used to monitor all Target-Types

without any deployed Plug-ins only the

Agent and the host would (and could) be monitored

Depending on the Plug-in, it needs to be

deployed to the OMS only or to both,

OMS and Agent

Plug-ins have independent release cycles

so every time you have a new version of an

Oracle product released, you will have a new

version of the plug-in released as well to

support monitoring of that new product version

in Enterprise Manager 12c Cloud Control

EM 12c – Prerequisites

There are some (minor) changes in the prereqs compared to 11g

(Example is for a "Small Configuration" on Linux)

Experience shows that these resources may not be sufficient

Especially RAM should be doubled if available!

Consult the documentation for complete prerequisites

Installation - News

Most important:

The installation is a lot more user friendly and intuitive, than former

releases (here as example, some counters regarding "simple installation")

Only ONE installer to install WLS and EM12c

No different Install Media for Install or Update – Full Installer

Logfiles can be viewed during installation process - from within the

installer

NEW: an Autofix option to fix problems with the repository database

during installation

JDK 1.6.0_24

Weblogic Server 10.3.5 – plus, it creates

- … a Domain called GCDomain

- … a NodeManager

- … an oracle common directory


- … one OMS

- … an Agent

- … the Repository (into an existing database)

IMPORTANT:

Enterprise Manager 12c does NOT support Agents of Releases < 12c

One-System Upgrade

Upgrades the currently running OMS and Repository Database

Comparable to an Oracle Single Instance Upgrade

Downtime: yes, as long as it takes to upgrade EM

One-System Upgrade using a different host

EM12c is installed on another server

But the Database of the old OMS is upgraded for EM12c

So, not much difference to One-System Upgrade?

Downtime: yes

Upgrade – Methods (1)

June 2012


2012 © Trivadis

Two-System Upgrade

Based on a Backup of the currently running Repository Database

On top of this Repository a EM12c OMS will be installed

The Repository Database will get upgraded to EM12c

A Database Link from the currently running system to EM12c will be created

- this provides synchronization with EM12c

Agents can be migrated one after another, both systems are active

Downtime: no

New Installation

Just install a completely new EM12c environment

Migrate Agents suited to your needs

Much simpler than an Upgrade, a fresh start

- but of course any configuration done is lost

Downtime: no, but administrative efforts

If it is possible for you, we recommend it

Installing the Management Agent – available Methods

Push Deployment

The agent will be installed from the OMS on the target host via SSH

Silent Installation

The agents installation sources are provided on the target host manually.

Afterwards a silent installation using a response file is done

RPM-based method

RPMs can be created which can be installed like every other RPM

Unfortunately this method has downsides and we do not recommend it

Shared Agent Installation

In this instance the agent is installed once and started on every machine via

NFS. To support this the Agent Instance directory is used for storing local data

June 2012


2012 © Trivadis

Managing Targets – Target Discovery (1)

Now that the Agent is installed we can use it to discover components

running on that Host

click

Setup -> Configure Auto Discovery

Next to

Multiple Target-Type Discovery

click on the wrench

Select the

Host and

click Configure

June 2012


2012 © Trivadis

Managing Targets – Target Discovery (2)

We select the target

types the agent

should look for …

… and click

Run Discovery Now

to tell the agent to

start discovering

targets

Some seconds later…

…the targets have

been discovered

June 2012


2012 © Trivadis

Managing Targets – Promoting Targets (1)

The process to convert a discovered target to a managed target is called

Promoting. We are showing this process using two discovered

databases.

We click on the number of discovered targets ("6" in our case)

Which will preset a list of all discovered, but unmanaged targets

We select one of the Database Instances and click Promote

June 2012


2012 © Trivadis

Managing Targets – Promoting Targets (2)

After entering the credentials of the user used for monitoring the

databases a summary is presented, we click Promote to start the

process of converting the targets to "managed" state

After a couple of minutes, the process finishes

June 2012


Notice: even though we only selected one of the databases, all targets of the same type are promoted

2012 © Trivadis

Named Credentials - Background

Named Credentails are in essence stored passwords with a tag

For security reasons there may be concerns with passing passwords

Even between DBAs

Named Credentials solve this issue

Example: Lets assume dba1 knows the password and wants to grant

dba2 access to a system but hesitates passing the password.

dba1 creates a Named Credential consisting of

- Username and Password

Then dba1 grants dba2 the right to use this named credential

CloudControl only presents the well known ******* to dba2, but

EM12c uses the stored password when logging in on behalf of dba2

June 2012


2012 © Trivadis

Named Credentials - Example

Scopes

Target

- Target Credentials are tied to a specific target

Global

- Global Credentials are valid for all targets of a given target type

Example:

June 2012

Privilege Delegation Providers - Background

For security reasons…

Setups exist where the oracle Operating System user is either

locked,

prohibited from logging in, or

the password is not known by the DBA

In these cases a Privilege Delegation Provider (PDP) is used

EM12c supports the two most common PDPs

Sudo, and

PowerBroker

Prerequisites need to be fulfilled

June 2012


2012 © Trivadis

Privilege Delegation Providers – Sudo Example

Prerequisites

The following parameters need to be set in /etc/sudoers

June 2012


(trivadis is the user which is used to log on to the system)

Configuration

Select Sudo as Privilege Delegation Provider (PDP)

Enter the Command to run: /usr/bin/sudo –E –u %RUNAS% %COMMAND%

the –E is important because of

Bug 13513154 (opened by Trivadis)

Target Management – Target Attributes

Each target has attributes

Lifecycle Status is the only field with

pre-defined values

Development, Test, Staging, Production and

Mission Critical are available

all other fields are standard text-fields

be aware of possible typos when using

these values for further processing

"R&D", "R & D", "Research & Development"

are distinct values

Fields can be added and removed by using emcli

# emcli add_target_property -target_type="host" -property="Manager"

# emcli remove_target_property -target_type="host" -property="Manager"

Target Management – Administration Group Hierarchy

To implement Adminstration Groups, a hierarchy has to be planned in

advance

once defined, this hierarchy cannot be altered, only dropped and recreated

This Hierarchy depends on how you manage services and systems in

your organisation

an example:

The first level is based on the Lifecycle Status of the target

The second level is based on the Target Type

Enterprise Monitoring – Basics

Metrics

are the basic building blocks of Enterprise Monitoring. Metrics are

checks whose results are compared to thresholds.

Events

are generated every time a metric or compliance check changes its state

(e.g. from "Warning" to "Critical")

Incidents

are generated from Events using Incident Rules. Incidents can be

assigned, escalated, given a priority or can be used to group similar

events together.

Incidents – Incident Rule Engine

The Incident Rules Engine is used to process Events

It consists of

Incident Rulesets (which have one or more..)

Incident Rules (which have one or more…)

Actions

Incident Rules and Actions reflect how

Administrators should be notified of events

Filter conditions can be used, for example

Event Type

Event Severity

Target Type, Target Name,….

Additionally it is possible to react on already created Incidents or Problems

For example: a Incident can be escalated if it is still unassigned after 24 hours

Unfortunately it is not possible to quit execution after a rule

Enterprise Monitoring – Incident Rules

Further processing of the Event takes place using Incident Rules

Incident Rulesets contain one or more Incident Rules

Incident Rules contain one or more Actions

To define which Rule (or more specific), which Action,

should handle the Event, a set of filters can be defined

for example: Every Metric Alert with a Severity of Warning, Critical or Fatal will…

… create an eMail to SYSMAN and create an Incident,…

… this incident will be assigned to SYSMAN and its Priority set to "Very High"

Much has changed since Enterprise Manager 11g

In almost every case to the better, but…

"with great flexibility comes great complexity"

Named Credentials, finally!

Ever had the Problem that Developers want to look at Real-Time Performance

Data using Enterprise Manager, but you don't want to give away the password

of the powerful user used?

Named Credentials are mandatory throughout the User Interface

Developing a Naming Convention is essential!

Is EM12c ready for production?

In general: Yes

still, you may want to test it in your environment, just like any other software

Conclusion – Enterprise Manager itself

June 2012


2012 © Trivadis

Private Cloud is an exciting feature

This could solve so many issues companies have at the moment

In conjunction with the Self-Service Portal Users can create and destroy

machines as the see fit, without bothering SysAdmins or DBAs

Our tests were quite successful!

Chargeback solves an old discussion

With Chargeback resources can be charged to the department using it

So IT can act as a Service Provider charging for their services

If you see fit: use it, its simple and powerful
