Security Console
• Ability to review Enterprise
Manager Security
• Not a traditional “Console”
• Information about best practices
• Violation to best practices
• Links to corrective steps

Secure Communication Page

Securing EM12c
• Do NOT log in at SYSMAN, create individual accounts.
• Use the MGMT_ADMIN_USER_PROFILE in 12c .
• Create privileges and roles for accessing EM12c.
• Create Global Named Credentials to hinder risks.
• Aggregate target privileges offer granule control of access.

Private Roles
• Roles that can be granted by one EM User to another EM User to manage
– Jobs
– Templates
– Targets tasks
• Allows Named Credential to be granted to a Role
• Creation can be done via the Console or the EM CLI, but only
“WITH_ADMIN” option required to create a private role can be done
through EM CLI GRANT_PRIVS verb call.

Credential Enhancements
• Assign credentials by default to a target, (no more logging in by user and
creating new credentials or unsecure credentials.)
• Targets credentials that are default for a specific target that will be used by
users granted access to the target.
• SSH credentials as Preferred Credentials
– Supported in earlier versions, but required manual edits to emd.properties and
sudoers file
– Now one just needs to update sudoers file

UI Enhancement
• Simple management via the
console.
• EM CLI verb if global
allocation desired.

Global Preferred Credentials
• Convenient System Wide Credentials
• Privileged Administrator can set Preferred Credentials for ALL users
– For a specific Target
– For a Target Type
• Efficient allocation of common Accounts
– Aid in new hire on-boarding
– User Scope Preferred Credentials
– System Scope Preferred Credentials

The Repository Page
• Configuration Validation
• Monitor and configure EM housekeeping tasks
• Deep Insight and visualization of collected metrics
• Identify space hogs and control schema retention policies

Enterprise Manager Page Performance
• Load and processing metrics shown for overall page
performance and individual page performance
• Breakdown by time spent in Repository, OMS and
Browser/Network
• Diagnostics report for pages taking >30 seconds to load

Improved Target Deployment
• Windows customers- PSEXEC built in!
– No more CYGWIN installations! 
– Simpler deployment
• Still recommend silent deploys or EM CLI scripts.

Enhanced Plug-in Deployment
• New Plug-in Deployment Wizard
allows multiple Plug-ins to be
deployed to the OMS in a single
deployment session
• Identifies Plug-ins that require an
OMS restart

Enhanced Threshold Management

Impressive New Self-Service Portal

Database as a Service Enhancements
• No longer hindered by storage platform!
• All are supported by either a hardware or software plug-in.
• Rapid Start deployment option with response file offers simpler
deployment solution.

Cloning with DNFS
 Ability to create thin databases from RMAN image copies
 Supported configurations
– Single instance databases
– ASM is not supported for this type of thin clone provisioning, (yet)
 Supported database versions
– 11.2.0.3-> DB12c
 Benefits
– Easy to setup without pre-requisites
– No special storage software needed
– Works on all platforms
– Instantaneous cloning with DNFS snap clone
– Create multiple clones based on one backup and consume very little space

More Cloning Enhancements! 
 Ability to create active thin clones of databases on ASM using EMC (currently VMAX
Enginuity Version: 5773 and above with Time Finder.)
 Use of Active DataGuard (ADG) standby as a master for creating snap clones
– Solves the problem of continuous replication
 Change profile attached to a service template
– Allowing an update of data without changing configuration
 ‘Live’ Full clones using RMAN duplicate
– Clones created from a live instance of database

JVMD as a Service
 JDaaS is designed to enable IT orgs to allow their users to consume
JVMD functionality in a self-service manner & manage all their JVMs
within a web based portal
 SSA users can enable JVMD on their JVMs regardless of JVMs being
targets in EMCC
 To enable the cloud, all that is required is to set the Quotas.
 Quotas are set to Roles and are in terms of number of monitored JVM
 Users use this functionality by downloading an agent from the SSA an
deploying it on the desired JVM.

Database
Comparing Performance Periods
Comprehensive System Monitoring
Incident Rules and Management
Groups

How Often Do We Ask, “What Changed?”
• It ran fine last week, now it no longer does!
• ETL loads have changed, but no one has released any new code!
• The DBA says there hasn’t been any parameter changes to this database,
but I’m sure there have been.
• Compare ADDM Resolution

What is Compare ADDM?
• Uses Two AWR snapshots
• Creates Report that-
– Compares SQL that is common and different.
– SGA changes
– IO/CPU bound issues
– Parameter Changes

What is in an ADDM Compare?
• Report Includes Following:
– Clear Demonstration of impact of change.
– Recommendations to address issue.
– Identifies causes behind change, (with limitations.)
– Lists Regressed SQL, too!
– Tip: If Installing to database for first time, (simple installation, nothing to concern
about, just pkg to fulfill views) you must have preferred credentials SET of install will
fail!

• Choose focus period
• Choose to compare to an Offset,
Baseline or Custom
Executing a Report from EM12c
Comparison

• Familiar interface with visual wait event
comparisons.
• Average # of sessions during each period are
displayed.
Main Screen of Comparison
2-3PM, 12th Vs. 13th

Detail Report
• High level data, highlight for analysis and recommendations.

Regression SQL
• Any performance degradation is noted with the down arrow icon:

Top Segments Causing IO Waits
• High Level data
• Click on “Show Hot Object Breakdown” to see more detail.

Resource Comparisons
• Comparisons of Memory, CPU, IO and Interconnect.
• Memory Is there Virtual paging?
• Memory Base Period
• Memory Comparison Period

Dashboard Provided for CPU, Memory, IO and Interconnect
• Is something OTHER than Oracle the cause?

IO Bound Dashboard
 Base vs. comparison period
 Temp reads/writes specified
 Single block read latency

Monitoring Templates
• Sets distinct, consistent monitoring for individual targets or groups.
• Still allows for individual metric policies and thresholds to be set
and not overridden by templates.
• Easy to maintain and can be automated to be set as “default”
template for targets/groups.

Creating a Monitoring Template
• Or part of administration group creation step.

Monitoring Template Design
• Base Templates off Existing Targets
• Build by Target Type
• Make Templates DEFAULT for Crucial Target Types.

Incident Rule Sets
• Two Default Rule Sets
• “Create Like” for the Default Rules Sets
• Build out New Ones
• Disable the Defaults

A Rule Set Can…..
• Be assigned to a Target, Target Type or a GROUP.
• Build out rule sets as complete as you need.

Rules
• Think about…
– What is important to be ACTUALLY notified for?
– What is TRULY mission critical?
– What should be managed during the business day?
– More notifications are NOT better notifications
– No, NO WHITE NOISE- make every notification count.

Defining Rules for Efficiency
• From default rule, but have eliminated all categories but Availability and
Capacity that are Critical.
• Email who is required to be notified AND
• Set the owner and the priority in the incident.

The Rest of the Categories
• Created a second rule
– Still severity has to be critical
– Covers all categories removed from original rule.
– No email notification- I want these to just create an incident.
– Sets the owner and the priority automatically.

Auto-Clear of Metric Rules
• Update how long till auto-clear
• Remove notification- no, I don’t want an email!

What about Warnings??
• No, there aren’t any rules set for warnings.
• I choose to use the incident manager to track warnings and pro-actively
manage from it.
• Severity Warning, creates and incident, sets the owner to SYSMAN and
priority to LOW.
• This is a PROFESSIONAL PREFERENCE.

When to Know to Change a Rule
• Notification does not provide value.
• Notification is triggered by a bug, isn’t critical or can’t be resolved by
the one notified.
• Always retain the email notification to ensure you are editing the
correct notification.
• Break down the rule to ensure that metrics grouped in one category
are not mistakenly set to not notify.

Everything You Need….

Edit the Rule from the Rule Set..

Search the Target Type and Metric

Add the Device to Exclusion List

Tips on Event Building
• Create New Rules and Break Down Categories
• Inspect Each Notification the Impacts Effective Alerting.
• Recognize when a metric threshold vs. a rule set is the “culprit”.

Edit Actions
• Choose if this should be done for all actions.
• Create Incident, automatically assign.
• Set a priority and even update information automatically in the incident.

Editing Actions, Cont.

Review Rule and Rule Sets

Incident Management
• Critical Notifications are now ONLY for Mission Critical and Production
Down
• The Incident Manager interface now can be utilized for review and
management.

An Incident
High Level Information regarding incident and links to details.

Incident Events
Steps covered in incident and escalation.

Incident Updates
• Steps through the updates to the incident.
• If any notifications have been sent, this is where you look!

Editing Thresholds for Incidents
• If Metrics Involved, Edit from Incident:

Set New Thresholds

Threshold Suggestions

Set the New Metric Thresholds
• Suggestions Have Verified- no Guessing.
• Upped Number of Occurrences to Eliminate False Alerts
• Choose if Monitoring Templates Can Override.

Groups and Admin Groups
• Groups ease management of targets, allowing assignment of tasks,
monitoring and other features through a single alias for multiple targets.
• Groups are still supported, but limited vs. what Administration groups offer
you. The one advantage is multiple group assignment of a single target.
• Administration groups set hierarchy and automate management by
assigning monitoring templates, compliance standards, and cloud policies.

Groups- Simple
• Creating Groups are like Creating Roles…
• Add targets to a group or more than one group at any time.
• Edit standard groups down the road.
• Groups can be used with rule sets to assign alerts to multi-level escalation
in actions.

Administration Groups- Complex
• Plan out first, including “Line of Business”, “Lifecycle Status” and what
types of databases exist in environment, (production, mission critical,
staging, development, QA, etc.)
• Once created, most design elements of the Administration group are not
open to edits.
• All hierarchy for each target is available in the “target properties”.

Setting up Admin Groups
• Click on Targets, Groups OR Setup, Add Target, Administration Groups
• Create, Choose Administration Group
Have your design ready…

Creation a Hierarchy
• Start with Lifecycle Status
• Decide which to keep, edit, add, remove or merge.

Create Your Line of Business
• Click on “Add” in Hierarchy Levels, (again)
• Choose Line of Business, click on Add, separate by a comma all lines of
business desired.

Simple Hierarchy is now built
• Development Hierarchy, (same for each Lifecycle status)

Create Hierarchy
• Click on Create, warning will appear-

• Monitoring Templates, (covered earlier), can be created as part of
this step.
• Compliance and Cloud standards must be created in the appropriate
framework in EM12c before being added to the Administration
Group.

Create and Choose Existing

Create the Template Collections
• Add all monitoring templates required of any life cycle.
• Note- No associations exist yet!

Run Unassociated Target Report
• Run Report to see what targets aren’t associated with Admin Groups.

Editing a Target
• Fill in all Pertinent Information

Post Association
• Associate Template Collection
• Continue with all Targets Till
Complete.

Dynamic Groups
• High Level Review

Define the Membership Criteria

Reviewing the Build
• The Membership can now easily build out from the criteria entered.
• Saves from having to build Admin Groups.

Charts
• Use Default Charts to Begin

Keep it Simple
• Use Default for Charts, Columns, Dashboard

Group Review
• Dynamic Easier, Fluid
• Administration- more complex, but open to more errors.

Summary-How This Works Together
• Automate-
– Monitoring Templates
– Rule Sets
– Dynamic Groups if you are not using Advanced Features
– Administration Groups if you want automation, auto-discovery/monitoring
• Efficiency
– Remove notifications that create “white noise”.
– Update metric thresholds.
– Silence metrics that offer no value.
