Ron,
I have urgent question. Because I want to shutdown my database, I login as
oracle and execute dbshut. But later I found that the process is very slow
so I realize that I should type shutdown immediate. Then, I use control-D to
stop shutdown command. And I re-execute shutdown immediate. Now
Don,
A normal shutdown will wait for all of the users to complete there
work and shutdown when the users are off the system. A shutdown
immediate wait for the current transactions to complete and not allow
any more to start before shutting down. A shutdown abort does just
that, I stops all
I'm not Ron; but I'll take a stab at this.
The shutdown immediate is hanging probably because there are several
transactions that are rolling back. The database is not going to close till
all have rolled back completely.
HTH.

Don,
The users need acces to the data that is in the database or what is
the purpose of the database?
I would change the privileges of the users to CREATE SESSION only
and revoke all others. Then I would use ROLES that have select
privileges on the tables that they need acces to. By creating
Hi Don,
I wrote a paper for securityfocus.com a while ago that described a
simple security scanner for Oracle, there is also a script you can run
with the paper. You can get the link on my Oracle security papers page
on my site at www.petefinnigan.com/orasec.htm, the paper is near the top

Dear Guang Mei:
Thanks for your message. Your suggestion is very helpful. After reviewing all possible
uesers, I have locked them. Now I have only one concern that if nobody knows my
database's sys and system's password, there should be no way to unlock these accounts.
Am I complete right?
Don
Well, if you changed the password, then you should have the new password.
Don't post them, because everyone on the internet will have them.
What is your Oracle version?

Hi,
I suggest you use sqlldr to load the data into the database.In most
case, sqlldr solves this kidn of questions.
Second, as dennis said, read more about oracle. oracle Is pretty
complicate, and it is hard to manage if you do not understand it. Besides
dba 101, you can get free books
Don
Interesting web site. Well, I think you have enough information from us.
Now it is just some detective work.
The next subject you need to review is backup and recovery. Keep the
information in those databases secure.

Hi,
I have a security question about Oracle database. Recently I have
taken
full control an Oracle database in my department. Now I would like to
make sure that no other people except myself can update data in that
Change the password of all Oracle related users (sys, system,...)
Revoke access from all other users or make sure all other users have select
only privilege on data.
What is the use of such databases ?

If only you can make updates to your Oracle database, then you must enter
all the data ;-)
From the tone of your posting, I'm going to assume that you are pretty
new to Oracle. You may want to get a good basic administration book like
Oracle9i DBA 101.
Stephane,
Thanks for your message. The reason I ask this question is that now I am
responsible for creating some reports based upon this database. But I have found
that there are unaccountable data in my database, which is not from my insert
script or my cron job program. Thanks!

Thanks for your message. Now I have changed sys password by the following
command:
alter user sys identified by xxx
But when I try to login from sql plus window by using sys, I cannot successfully
login. Also I get an error message. The message is something like connection to

SYS is the owner of the Oracle dictionary tables. It is a username with
DBA privilege, so someone who logs in can change data. If you have changed
its password, then you are assured that nobody is using that username right
now. If you've changed its password, then I wouldn't worry about
Oops. I meant to say that you might consider changing the PASSWORD of the
username that owns your tables.

Thank you very much. My data in that database is changed three times. The first
is whole data being delete. The second is over ten thousands records being
added. The third is whole data related to a month being deleted. I know my
working environment is very complicated. For this report
objects (like a public PLAN_TABLE or the PRODUCT_USER_PROFILE table.)

Thanks for your message. Now
select * from all_users;
to get all users, then change their oracle passwords so that no body can
log in except you. This way you know you are the only one who can change
the data. Next step is see what application can make the data change.
Hope this helps.
