SQL Script

Table Extents for Given Owner

Updated: 01-Jun-1998
Version: 1.0

Description

This script first gives a list of tablespaces. It then prompts to enter a tablespace name and a minimum value of extents. The script then lists all tables and indexes with the the number of extents greater than the value entered. 

This is a MUST script for all production DBA's. 

It can easily be amended to be put in a nightly schedule. You can spend a lot of cash on database monitoring utilities to do this for you, but it's very simple !!

Parameters

tspace - The tablespace to report on
min_ext - the minimum number of extents
