10 Gb fine-grained Audit
In Oracle 9i Database, this policy can only audit select statements. However, in Oracle Database 10g, you can extend it to include insert, update, and delete. You can achieve this by specifying a new parameter:
Statement_types => 'insert, update, delete, select'
This parameter enables audit for all included statement types. You may eve

Excuse me, are you familiar with netbeans? I use netbeans to open a file. it occasionally uses UTF-8 as a gb file. what is the problem? Netbeans UTF-8
This problem occurs:
It can be determined that a CSS file is saved in UTF-8 format.
On the one hand, this file was originally created through netbeans, but now it is saved outside of the project as a separate file to open.
On the other hand, it has been verified using other editors.
