You can disable redo for direct load inserts. Look up the NOLOGGING clause and the /*+ APPEND */ hint. There are some implications for concurrency and data integrity that need to be aware of.

NOLOGGING clause can be used at the end of insert statement.... But I am using an application which insert data to a table...
Is there any way that I solve this problem at server side means any trigger or other setting......

Actually I am using purchased application which insert data in a database table......
Now by default logging is enabled and all the operations are going well.
I want that no redo should be generated against a specific table only for insert statement.... because this cause heavy archived log and ultimately flash recovery area full...........
Please guide me to solve this issue...

Do you understand that no logging means not recoverable?
That is if you lose a disk or a file you lose your data, is this what you want?
If yes, then just put your database in NOARCHIVELOG mode.

If yes then how to do it....

No I don't think you REALLY understand what this means otherwise you would not ask for this.
Do you REALLY understand that means inconsistencies in your data after a failure?
Do you REALLY understand that your application will no more work?
Do you REALLY understand that means your customers will go away and find a more reliable entreprise?
What do you think if you go to your bank to ask for your money and the answer is "You have no account in this bank!"?

The first requirement is to retrieve the data you gave NOT to have less logs.

Your requirement is impossible, and so it is meaningless.

You need to cope with the fact that you are getting lots of redo.
