    Abstract: Any organization that uses the Oracle relational database management system (RDBMS) these days needs to use multiple databases. There are many reasons to use more than a single database in a distributed database system: Different databases may be associated with particular business functions, such as manufacturing or human resources. Databases may be aligned with geographical boundaries, such as a behemoth database at a headquarters site and smaller databases at regional offices. Two different databases may be required to access the same data in different ways, such as an order entry database whose transactions are aggregated and analyzed in a data warehouse. A busy Internet commerce site may create multiple copies of the same database to attain horizontal scalability. A copy of a production database may be created to serve as a development test bed. Tunability Platform autonomy Fault tolerance Scalability Location transparency Site autonomy Introduction to Distributed Database Systems SQL*Net and Net8 Configuration and Administration Distributed Database Security Designing the Distributed System Oracle's Distributed System Implementation Sample Configurations 8. Engineering Considerations Oracle Replication Architecture Advanced Replication Option Installation Basic Replication Multi-Master Replication Updateable Snapshots Procedural Replication Conflict Avoidance and Resolution Techniques In a distributed database environment, data in two or more databases is accessible as if it were in a single database. Usually, the different databases are on different servers, which may be located at the same site or a continent away. Communication between the servers takes place via SQL*Net (for Oracle7) or Net8 (for Oracle8). Distributed database environments offer a number of benefits over single- database systems, including: This book describes how you can use multiple databases and the distributed features of Oracle to best advantage. It covers: Table of contents: Part I: The Distributed System Part II: Replication Part III: Appendixes Appendix A: Built-in Packages for Distributed Systems Appendix B: Scripts

    Oracle built-in packages (1998)

    Abstract: Oracle is the most popular database management system in use today, and PL/SQL plays a pivotal role in current and projected Oracle products and applications. PL/SQL is a programming language providing procedural extensions to the SQL relational database language and to an ever-growing number of oracle development tools. originally a rather limited tool, PL/SQL became with Oracle7 a mature and effective language for developers. now, with the introduction of Oracle8, PL/SQL has taken the next step towards becoming a fully realized programming language providing sophisticated object-oriented capabilities. Steven Feuerstein's Oracle PL/SQL Programming is a comprehensive guide to building applications with PL/SQL. That book has become the bible for PL/SQL developers who have raved about its completeness, readability, and practicality. Built-in packages are collections of PL/SQL objects built by Oracle Corporation and stored directly in the Oracle database. The functionality of these packages is available from any programming environment that can call PL/SQL stored procedures, including Visual Basic, Oracle Developer/2000, Oracle Application Server (for web-based development), and, of course, the Oracle database itself. Built-in packages extend the capabilities and power of PL/SQL in many significant ways. for example: DBMS_SQL executes dynamically constructed SQL statements and PL/SQL blocks of code. DBMS_PIPE communicates between different Oracle sessions through a pipe in the RDBMS shared memory. DBMS_JOB submits and manages regularly scheduled jobs for execution inside the database. DBMS_LOB accesses and manipulates Oracle8's large objects (LOBs) from within PL/SQL programs. 1. Introduction Executing Dynamic SQL and PL/SQL Intersession Communication User Lock and Transaction Management Oracle Advanced Queuing Generating Output from PL/SQL Programs Defining an Application Profile Managing Large Objects Datatype Packages Miscellaneous Packages Managing Session Information Managing Server Resources Job Scheduling in the Database Snapshots Advanced Replication Conflict Resolution Deferred Transactions and Remote Procedure Calls The first edition of Oracle PL/SQL Programming contained a chapter on Oracle's built-in packages. but there is much more to say about the basic PL/SQL packages than Feuerstein could fit in his first book. In addition, now that Oracle8 has been released, there are many new Oracle8 built-in packages not described in the PL/SQL...
