“Dashboard” for the DBA

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

Drill-down capability Launch pad for all DBA

activities

Managing Groups of Databases

Manage all your databases from one place

At 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 systems

Allows organizing the enterprise as different logical groups and dividing work amongst users by granting appropriate access privileges

Allows users to create groups containing sets of targets Homogeneous groups

– Group of databases Heterogeneous 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 systems

Pre-packaged jobs– SQL and OS– Start-up/shutdown,

backup, patch, clone …

Ad-hoc job creation – Custom scripts

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-levelrecommendations

Stored in EM Repository Extensible PL/SQL

package




Enterprise Manager





State-of-the-Art Availability Management

Standby System(Data Guard)

ProductionSystem (RAC)

Enterprise Manager

Real Application Clusters (RAC) Data Guard Backup and Recovery

RAC Management User Transparency

– Same functionality as single instance Cluster awareness

– Database– Hosts (OS)

Database-level alerts– e.g. storage alerts

Cluster-aware EM jobs RAC-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 check Switch-over / fail-over Protection mode management

– Choice of availability vs. performance

Data Guard Section onDatabase home page

Backup & Recovery Management

Guided 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 restoration Backup 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




Enterprise Manager





Integrated Storage Management

Database Storage Administration– Tablespaces– Datafiles– Redo logs– Rollback segments– Archive logs

File Topology OMF Support Management of ASM

File Topology

Mapping of Oracle files to physical storage locations

– Data Files– Control Files– Redo Logs– Archive Logs

Facilitates I/O diagnostics and storage optimization

Enabled for ASM, EMC, VxVM, HP etc.

Managing ASM

EM Target– In context of database

Integrated Performance Management

Disk Group Configuration Capacity Provisioning

– Adding / Removing Disks– Online

RAID Settings (at file level) Disk Repair and Rebalancing
