How to change table monitoring setting

I'm working on improving Oracle tables' performances.

The table that I have been working on created with 'monitoring' and 'logging' clause. These two, decreasing performance of query and I need to change monitoring to nomonitoring(without dropping tables).

This is working well:

alter table some_table nologging

But to alter monitoring to nomonitoring I use;

alter table some_table nomonitoring

query executes without any errors but there is no change in table structure.

I've been researching on internet for days and also as I saw here there is no such topic for my specific problem.

Thanks in advance.

Solution

The monitoring/nomonitoring options are deprecated and are no longer used in Oracle.

Quote from the Oracle 11.2 manual

Formerly, you enabled DBMS_STATS to automatically gather statistics for a table by specifying the MONITORING keyword in the CREATE (or ALTER) TABLE statement. Starting with Oracle Database 11g, the MONITORING and NOMONITORING keywords have been deprecated and statistics are collected automatically. If you do specify these keywords, they are ignored.
