  2. Course Objectives • After completing this course, you should be able to do the following: • Install, create, and administer Oracle Database 10g • Configure the database for an application • Employ basic monitoring procedures • Implement a backup and recovery strategy • Move data between databases and files

  3. Suggested Schedule • 1. Introduction • 2. Installation • 3. DB Creation • 4. Instance • 5. Storage • 6. Users • 7. Schema • 8. Data & Concurrency • 9. Undo • 10. Security • 11. Network • 12. Proactive Maintenance • 13. Performance • 14. Backup & Recovery Concepts • 15. Backup • 16. Recovery • 17. Flashback • 18. Moving Data

  4. Lesson Objectives • After completing this lesson, you should be able to do the following: • Describe the course objectives • Explain the Oracle Database 10g architecture

  5. Oracle Products and Services • Oracle databases • Oracle Application Server • Oracle applications • Oracle Collaboration Suite • Oracle Developer Suite • Oracle services

  6. Storagegrid Databasegrid Applicationgrid Gridcontrol Automatic Storage Management Real Application Clusters Oracle Streams Enterprise ManagerGrid Control Oracle Database 10g:“g” Stands for Grid • Global Grid Forum (GGF) • Oracle’s grid infrastructure: • Low cost • High quality of service • Easy to manage

  7. Oracle Database Architecture • An Oracle server: • Is a database management system that provides an open, comprehensive, integrated approach to information management • Consists of an Oracle instance and an Oracle database

  8. System Global Area (SGA) Background processes Database Structures DB structures - Memory - Process - Storage Memory structures Instance Process structures Database files Storage structures

  9. Oracle Memory Structures . DB structures > Memory Process Storage Server process 1 Server process 2 Background process PGA PGA PGA SGA Streams pool Large pool Shared pool Database buffer cache Redo log buffer Java pool

  10. SGA Process Structures DB structures Memory > Process Storage • User process: Is started at the time a database user requests a connection to the Oracle server • Server process: Connects to the Oracle instance and is started when a user establishes a session • Background processes: Are started when an Oracle instance is started Instance PGA Server process User process Background processes

  11. Oracle Instance Management SGA Shared pool Streams pool Large pool Java pool Database buffer cache Redo log buffer System Monitor (SMON) Process Monitor (PMON) Database Writer (DBWn) LogWriter (LGWR) Archive log files Checkpoint (CKPT) Archiver (ARCn) Control files Data files Redo log files

  12. DBWn Server Process and Database Buffer Cache • Buffers: • Pinned • Clean • Free or unused • Dirty Server process SGA Database buffer cache Data files

  13. Physical Database Structure . DB structures Memory Process > Storage • Data files • Online redo log files Control files • Parameter file • Backup files • Archive log files • Alert and trace log files • Password file

  14. USERS tablespace Tablespaces and Data Files • Tablespaces consist of one or more data files. • Data files belong to only one tablespace. Data file 2 Data file 1

  15. SYSTEM and SYSAUX Tablespaces • The SYSTEM and SYSAUX tablespaces are mandatory tablespaces. • They are created at the time of database creation. • They must be online. • The SYSTEM tablespace is used for core functionality (for example, data dictionary tables). • The auxiliary SYSAUX tablespace is used for additional database components (such as the Enterprise Manager Repository).

  16. Segments, Extents, and Blocks • Segments exist within a tablespace. • Segments are made up of a collection of extents. • Extents are a collection of data blocks. • Data blocks are mapped to disk blocks. Segment Extents Data blocks Disk blocks

  17. Logical and Physical Database Structures Logical Physical Database Data file Schema Tablespace Segment Extent OS block Oracle datablock

  19. Database Architecture:Summary of Structural Components • Memory structures: • System Global Area (SGA): Database buffer cache, redo buffer, and various pools • Program Global Area (PGA) • Process structures: • User process and Server process • Background processes: SMON, PMON, DBWn, CKPT, LGWR, ARCn, and so on • Storage structures: • Logical: Database, schema, tablespace, segment, extent, and Oracle block • Physical: Files for data, parameters, redo, and OS block

  20. Summary • In this lesson, you should have learned how to: • Install, create, and administer Oracle Database 10g • Configure the database for an application • Employ basic monitoring procedures • Implement a backup and recovery strategy • Move data between databases and files
