Hi Guys,

I want to know where is the log of Select statement stored. I dont think that Redo log contains this information. Why does there is no log switch when firing a Select Statement when fetchin millions of data.

Hi Tanvi,

>> want to know where is the log of Select statement stored.

Nowhere! It would cost too much in disk storage!

You can turjn-on select auditing, but on a busy database, it can generate terabutes per hour in log files:

Good Luck!

The only way a select statement can be captured is via auditing. You can also see select statements in the library cache, but that is not persistent storage.

What is the purpose of redo in Oracle? Does a select statement change anything? No, so what is there to be re-done?

Here is a list of some books on Oracle. If you are new to Oracle, spend some time on reading books and the documentation.;q=easy+oracle
