Enterprise Manager Consolidation Planner

Again I will do my post in the form of a summary of features. Simply need some more time to revise these posts, so stay tuned. For now this is what I wanted to share with you guys.

Yes these are my notes in Stagato Style, sorry guys.

For planning the consolidation of multiple server to one server

Plans based on collected resource history data for a certain time interval

Cloud Consolidation Planning Workflow

  • Collect data from source servers
  • Select resources to be analyzed
  • Define constraints
  • Specify Target Servers
  • Review Consolidation Plan Results

User creates consolidation project and defines:

Type of consolidation P2P P2V

Source servers

After source data collection you can analyze the gathered data and resource usage trends.

Consolidation Analysis

  • Consolidation scenario specifies which metrics will be analyzed for the purpose of the consolidation exercise
  • Resource requirements fir each source server calculated
  • Each resource aggregated to 24-hour patterns based on specified formula
    • Conservative
    • Medium
    • Aggressive

Consolidation constraints

Use constraints to specify which server workloads can be placed together and which workloads must be kept apart for business or technical reasons

Consolidation planner uses SPECint data related to specific processor types

Policies for existing servers – Fewest Servers, Even distribution

Specify Maximum Resource Utilization % on Target Servers

Exadata Target Planning, to use Exadata as a Target platform

Server Mapping (the actual running of the consolidation)

Automatic Mapping of Source Servers onto Target Servers

Manual Mapping can be used on existing servers


Consolidation scenario report available after running scenario


  • Identify under-utilized and over-utilized servers
  • Help admins determines candidates for consolidation
  • Work physical and virtual


  • Metering and Chargeback enable cloud consumers to take control of their costs
  • Cloud empowers end-users to provision resources onto shared infrastructure using self-service
  • Without chargeback there can be a perception that cloud resources are ‘ free’
  • Without metering charges will be flat regardless of usage

Chargeback – Key Concepts

  • Charge Item
    • Targets that are chargeable
    • Charge Plan
      • Defines the charge items and associated rates that will be used for charge calculations
      • Cost Center
        • Organization unit that will be charged for the costs
        • Reporting Cycle

Chargeback Workflow

Select targets for metering

Define charge plans

Define cost center hierarchy

Assign charge items to charge plan

Target metering dedicated and shared mode

Dedicated mode consumers using the target are from the same cost center

Shared mode: consumers using the target are from different cost centers

Setup charge Plan

  • Simplest way to leverage chargeback
  • Contains 3 universal charge items
    • CPU
    • Memory
    • Storage
    • Can be assigned to any type of supported chargeback target
    • Extended charge plan
      • Target specific charges
        • VM machine size
        • Database Option
        • Host OS
        • WebLogic User Requests
  • Supports fixed, configuration and usage based rates
  • Can leverage the universal plan with universal rate adjustment
  • Extended Plan conditions
    • Under specific conditions

Define Cost Centers

  • Used in aggregation in Charge reports
  • Import from LDAP option
    • OID
    • AD
    • Open LDAP
    • Novel EDirectory
    • SUN IPlanet
    • Default cost center sued for unassigned targets

Charge Plan and Cost Center Assignment

Chargeback admin uses target and plan assignment


  • Daily job calculates all charges for current reporting cycle
  • Ad-hoc reports available from chargeback reports tab
  • Chargeback tab in self-service portal provide summary
  • Trending shows charge and utilization trend over specific period
  • BI Publisher – Generate Reports in variety of formats
  • Email reports to recipients

Chargeback – MRB integration

Integrate with oracle billing and revenue management
