Enterprise Manager 10G Database Management Oracle World 2003

Agenda  Enterprise Manager 10G Design Goals  Database Management – Information Central and Complete Database Administration – Troubleshooting – Performance Tuning – Managing Availability – Managing Storage – Managing the Oracle Software Lifecycle  Summary  Q &A

Enterprise Manager 10G Design Goals  Facilitate management of sets of systems  Access by anybody, anywhere  Zero-implementation time-to-value  Intimate connection to Oracle  1-Hour integration, industry standards  Open schema

Enterprise Manager 3. Studio Mode Agent Enterprise Manager 1. Grid Control Enterprise Manager 2. Database Control Deployment Modes Agent http(s) XML SQL*Net

Database Home Page  “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  Authentication Job System Enterprise Manager

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-level recommendations  Stored in EM Repository  Extensible PL/SQL package

State-of-the-Art Availability Management Standby System (Data Guard) Production System (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 on Database 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 (3 rd 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

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 Management Integrated Volume Manager and Database File System

Cloning  Cloneable Entities: – Installations (Oracle Homes) – Databases – Schemas with data (subset)  Multicasting  Base Image Library – Installations – Databases

Database Cloning  Cloning an entire database – RMAN-based – Clone library – Online (with Archivelog mode) – Scheduled as EM job  Schema Cloning – Change Management Pack – DBLINK-based – Schema and data (subset) cloning – Version and platform independent Cloning Wizard

Automated Patch Application Repository Enterprise Manager Patch Published 1 Determine Applicability 2 Apply Patch 3 Update Inventory 4  Real-time discovery of new patches  Security patch rapid deployment dramatically reduces vulnerabilities  Grid-wide automated application reduces down-time from human error
