SQL> select count(1)
2 from dual;

COUNT(1)
----------
1

Because there's just one column and one row that's why you'll always get 1. Here's what inside the DUAL table.

SQL> select * from dual;

D
-
X

Hi there Sorry for the late reply. I don't see any reason to use LONG data type in 10g database! Oracle strongly recommend to use and convert existing data to the LOB data types (BFILE) in 10g, it exists only for backward compatibility. A BFILE column or attribute stores a file locator that points t...

The RMAN and some other third party backup solutions using RMAN scripts in the background are used for that purpose. In the cold backup you just need to shutdown the dat...

Hi

I don't think so, oracle will get confused with the same global name (i.e mydb.abc.com) in a network. But if it's different domain then there's no harm to create it. Like "mydb.abc.com" and "mydb.xyz.com".

Hi

They are not icon but mounting point directories. All file system has to be mounted before it's used in Linux. Whenever you plug-in USB, OS creates a directory on your desktop and mount USB in to that directory.

Hope that's answer your question.

Hi

I would try running that script manually from shell prompt after setting up ORA env variables without passing any arguments:

. oraenv

$ORACLE_HOME/bin/dbstart

$ORACLE_HOME/bin/dbshut

Let's figure out first, which script is causing error.
