TABLE_NAME                     RPB
------------------------------ ----------
DIM_CUSTOMER                   12.7007752
DIM_DAILY_CALENDAR             25.1674347
DIM_LOCATION                   125.068702
DIM_HIST_RPTLOC                36.2477876
DIM_MSA                        86.2315789
DIM_PRODUCT                    12.8501961
DIM_ITEM_LOCATION              62.5343511
 

Based on the above we would examine the DIM_LOCATION, DIM_MSA and DIM_ITEM_LOCATION tables with the idea of reducing their rows per block. The other tables we would look at ini_trans and freelists. However, these aren’t always the solution as is shown in the next phase of our investigation.

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.
