Urge to Purge Part 3

Another area to help identify tables that can be purged is for high number of similar tables. The query below will identify tables with similar names, note that you may need to adjust the numbers to better identify such tables. Some examples of cases like this from Oracle's E-Business Suite are listed out below.

The query to use:
select substr(table_name, 1, 15), count(1)
from dba_tables
group by substr(table_name, 1, 15) having count(1) > 30
order by 2 desc;

In Oracle E-Business Suite there are several cases where interim and temp tables are not being cleaned out by the application. Below are a few cases that depend on the module used and the current release of the applications.

There are a couple of groups of temporary tables that have not been cleaned out by Oracle. These tables can be manually removed, but review notes indicated below to check that. The tables may not be causing any significant issues, they are just consuming space on the system. These objects can also slow down gathering object level statistics if there are a large number of them.
