Chapter 6 Oracle Tablespace and File Internals Scripts

Example 3: Create a bigfile tablespace and change its size

DATAFILE ‘/u02/oradata/grid/user_tbs01.dbf’ SIZE 1024 M;
In previous release of Oracle server, K and M were used to specify storage size. Notice in this DDL statement, a user can specify size in gigabytes and terabytes using G and T respectively.

Example 4: Using DBVERIFY utility with bigfile

With smallfile tablespace, you can run multiple instances of DBVERIFY in parallel on multiple datafiles in order to speed up integrity checking for a tablespace.  You can achieve integrity checking parallelism with BFTs by starting multiple instances of DBVERIFY on parts of the single big file.

$dbv FILE=bigfile01.dbf  START=1 END=10000
$dbv FILE=bigfile01.dbf  START=10001

Note: START = Start Block; END = End Block

Oracle10g Cross Platform Transportable Tablespaces

A transportable tablespace allows you to quickly move a subset of an Oracle database from one Oracle database to another.  However, in previous release of Oracle server, you can only move a tablespace across Oracle databases within the same platform.

Oracle 10g is going one step further by allowing you to move tablespace across different platforms.

Mike Ault’s Oracle Internals Monitoring & Tuning Scripts

Written by the world's top DBA and author of over 20 Oracle books, Mike Ault shares his secrets for Oracle DBA management scripts.  This handy reference is indispensable for all Oracle professionals who must quickly automate and manage their Oracle databases with scripts.

This stellar book comes complete with an online code depot full of over 200 pre-tested Oracle DBA scripts, and covers all areas of Oracle database administration including data files, tablespace, table and index management scripts.  Based on more than 20 years full-time experience, Mike Ault brings his expertise to the public with this fantastic book.  Your time savings from a single script is worth the price of this great book.

Mike Ault is one of the leading names in Oracle technology.  The author of 20 books and hundreds of articles in national publications, Mike was the first popular Oracle author with his landmark book "Oracle7 Administration and Management".  Mike also wrote several of the "Exam Cram" books, and enjoys a reputation as a leading author and Oracle consultant.

Mike started working with computers in 1979 right out of a stint in the Nuclear Navy. He began working with Oracle in 1990 and has since become a World Renowned Oracle expert (in the words of his publisher anyway!) Mike has written 14 Oracle related books, dozens of articles, and has presented at conferences in Europe and the USA. Mike has two wonderful daughters and is kept out of trouble by his wife of 29 years, Susan.
