This manual prepares you to successfully implement parallel processing by providing a thorough presentation of the concepts and procedures involved. Information in this manual applies to the Oracle7 Parallel Server running on all operating systems.
This chapter introduces parallel processing and parallel database technologies, which offer great advantages for online transaction processing and decision support applications.
Chapter 2: Successfully Implementing Parallel Processing
This chapter explains how to attain the goals of speedup and scaleup, by effectively implementing parallel processing and parallel database technology.
Chapter 3: Parallel Hardware Architecture
This chapter describes the range of available hardware implementations which allow parallel processing, and surveys their advantages and disadvantages.
This chapter gives a high-level view of how the Oracle Parallel Server provides high performance parallel processing.
Chapter 5: Oracle Instance Architecture for the Parallel Server
This chapter explains features of Oracle multi-instance architecture which differ from an Oracle server in exclusive mode.
Chapter 6: Oracle Database Architecture for the Parallel Server
This chapter describes features of Oracle database architecture that pertain to the multiple instances of a parallel server.
Chapter 7: Overview of Locking Mechanisms
This chapter provides an overview of the locking mechanisms that are internal to the parallel server. Note that the distributed lock manager (DLM) is external to the Oracle Parallel Server.
Chapter 8: Distributed Lock Manager: Access to Resources
This chapter explains the role of the DLM in controlling access to resources in a parallel server.
Chapter 9: Parallel Cache Management Instance Locks
This chapter provides a conceptual overview of PCM locks. The planning and allocation of PCM locks is one of the most complex tasks facing the Oracle Parallel Server database administrator.
Chapter 10: Non-PCM Instance Locks
This chapter describes some of the most common non-PCM instance locks.
Chapter 11: Space Management and Free List Groups
This chapter explains space management concepts.
Chapter 12: Application Analysis
This chapter provides a conceptual framework for optimizing OPS application design.
Chapter 13: The Parallel Query Option on OPS
This chapter covers issues relating to the Parallel Query option running on Oracle Parallel Server:
This chapter prescribes a general methodology for designing systems optimized for the Oracle Parallel Server.
Chapter 15: Creating a Database & Objects for Multiple Instances
This chapter describes aspects of database creation that are specific to a parallel server.
Chapter 16: Allocating PCM Instance Locks
This chapter explains how to allocate PCM locks to datafiles by specifying values for parameters in the initialization file of an instance.
Chapter 17: Ensuring DLM Capacity for All Resources & Locks
This chapter explains how to reduce contention for shared resources and gain maximum performance from the parallel server by ensuring that adequate space is available in the DLM for all the locks and resources your system requires.
Chapter 18: Using Free List Groups to Partition Data
This chapter explains how to allocate free lists and free list groups to partition data. By doing this you can minimize contention for free space when using multiple instances.
This chapter describes how to administer instances of a parallel server.
Chapter 20: Tuning the System to Optimize Performance
This chapter provides an overview of tuning issues.
Chapter 21: Monitoring Views & Tuning Oracle7 Parallel Server
This chapter describes how to monitor performance of a parallel server by querying data dictionary views and dynamic performance views. It also explains how to tune a parallel server.
Chapter 22: Backing Up the Database
This chapter explains how to protect your data by archiving the online redo log files and periodically backing up the datafiles, the control file for your database, and the parameter files for your instances.
Chapter 23: Recovering the Database
This chapter describes Oracle recovery features on a parallel server.
Chapter 24: Migrating from Single Instance to Parallel Server
This chapter describes database conversion: how to convert from a single instance Oracle7 database to a multi-instance Oracle7 database using the parallel server option.
This appendix describes the differences between this release and previous releases of the Parallel Server Option.
Appendix B: Initialization Parameters
This appendix lists initialization parameters important to the effective operation of your parallel server.
Appendix C: Dynamic Performance & Monitoring Views
This appendix describes views that can be used to monitor your parallel server.
Appendix D: Session Wait Events for Oracle Parallel Server
This appendix describes session wait events which are relevant to a parallel server.
Appendix E: Enqueue and Lock Names
This appendix provides detailed definitions of enqueues and locks.
Appendix F: Restrictions
This appendix documents Oracle Parallel Server compatibility issues and restrictions.
Suggestion: The lightbulb highlights suggestions and practical tips that could save time, make procedures easier, and so on.
Warning: The warning symbol highlights text that warns you of actions that could be particularly damaging or fatal to your operations.
For example, "If you create a private rollback segment, the name must be included in the ROLLBACK_SEGMENTS parameter of the parameter file."
An example of a definition is the following: "A database is a collection of data to be treated as a unit. The general purpose of a database is to store and retrieve related information, as needed."
An example of a reference to another book is the following: "For more information, see Oracle7 Server Tuning."
An example of an emphasized word is the following: "You must back up your database regularly."
INSERT INTO emp (empno, ename) VALUES (1000, 'SMITH');
ALTER TABLESPACE users ADD DATAFILE 'users2.ora' SIZE 50K;
Example statements may include punctuation, such as commas or quotation marks. All punctuation in example statements is required. All example statements terminate with a semicolon (;). Depending on the application, a semicolon or other terminator may or may not be required to end a statement.
Uppercase words in example statements indicate the keywords within Oracle SQL. When issuing statements, however, keywords are not case sensitive.
Lowercase words in example statements indicate words supplied only for the context of the example. For example, lowercase words may indicate the name of a table, column, or file.
