Out-of-Box ReadyRealize Immediate Value

Grid Control– Management of all the

Oracle Grid components– Centrally manage entire

enterprise– Out-of-box management for

all Oracle products

Product Controls– Fully functional standalone

management– Out-of-box with each

product

Database Home Page

“Dashboard” for the DBA

– Database status– Host information– Availability– Performance– Alerts

Drill-down capabilityLaunch pad for all DBA activities

Managing Groups of Databases

Manage all your databases from one placeAt a glance:

– Availability– Performance– Alerts

Drill-downs– Database details– Host details– Storage details

Enterprise Manager Groups

Provides an efficient way to manage large numbers of systemsAllows organizing the enterprise as different logical groups and dividing work amongst users by granting appropriate access privilegesAllows users to create groups containing sets of targetsHomogeneous groups

– Group of databasesHeterogeneous groups

– Components of a business application (database, listener, application server, host systems)

Versatile Enterprise Manager Job System

Execute simple or complex tasks across 100s of systemsPre-packaged jobs

– SQL and OS– Start-up/shutdown,

Best Practice Tuning

Oracle Database 10G Features– Automatic Database Diagnostic Monitor (ADDM)– Policy Violations– Automated SQL Tuning– SQL Assessments– Automatic Shared Memory Tuning– Space Tuning

Policy Violations

Automatically compares configuration to best practice rules Oracle’s best practices, e.g.

– Parameter usage– Space– Availability– Security– New features

Database and instance-levelrecommendationsStored in EM RepositoryExtensible PL/SQLpackage

State-of-the-Art Availability Management

Standby System(Data Guard)

ProductionSystem (RAC)

Enterprise Manager

Real Application Clusters (RAC)Data GuardBackup and Recovery

RAC ManagementUser Transparency

– Same functionality as single instanceCluster awareness

– Database– Hosts (OS)

Database-level alerts– e.g. storage alerts

Cluster-aware EM jobsRAC-specific performance management

– e.g. cluster cache coherency– Service / module / action and client ID

Cluster operations– Node add and delete– Minimal downtime updates

Service Assurance Management (Oracle Database 10G)

– Preferred and available instances to deliver service

Data Guard Management

Add and configure standby database

– Logical and physical– Standby creation from backup

Log transport & apply monitoring & management

– e.g. real-time log apply– Alerts

On-demand standby health checkSwitch-over / fail-overProtection mode management

– Choice of availability vs. performance

Data Guard Section onDatabase home page

Backup & Recovery ManagementGuided backup strategy creation

– Oracle recommended strategies– Custom strategies

Objects, window, location, incremental / full, compression

– Flash Recovery Area aware– Disk and/or tape (3rd party media

managers)Guided recovery

– Fine-grain restore/recovery (data file, tablespace, archive logs, blocks)

– Database and tablespace point-in-time recovery

– SPFILE & control file restorationBackup Management

– RMAN catalog maintenance (view, cross-check, delete, etc.)

– Recovery catalog configuration (database registration, location etc.)

Flash Recovery Area management – Rolling forward of backups using Flash

Recovery Area– Configuration (location, size)– Alerts

Flashback Database management– Point-in-time recovery based on

flashback logs– Configuration (en-/disable)– View usage and flashback horizon
