Is it possible? If no, then what can be done to achieve below.
I have a userid which has all the update, delete privileges on it. That id needs to be configured in the application alongwith the password. So in order to avoid misuse of that id I want to block its sql access.
I am not sure whether this can be achieved or not.

After changing the password he is not able to logon. The aud$ table does not show any occurrence of 1017, therefore it is not a question of Invalid password.
LVV> show parameter SEC_CASE_SENSITIVE_LOGON

When reviewing failed login attempts with this query:
SELECT username, os_username, userhost, terminal, to_char(timestamp,'dd-mon-rrrr hh:mi:ss')
FROM sys.dba_audit_session
WHERE returncode != 0
and trunc(timestamp) >= trunc(sysdate-1)
ORDER BY 5
I find some records for a username that does not exist. In any of my databases. I presume that if an attempt to a nonexistent user was made, it would be rejected before it gets to the db. But then again, a bad password would also be rejected.
I just want to know the user login / log out information for the past 31days. how can i get that?

DELETE FROM GR_GUEST WHERE GUEST_NAME='Ambassador Jack Binns bring Patrick Clawson' AND RESERVATION_ID_FK=21635
It gives an ORA-01460 which is "unimplemented or unreasonable conversion requested"Removing the " AND RESERVATION..." gives the same error.
The problem is that GUEST_NAME is a VARCHAR (150) and RESERVATION_ID_FK is an INT so I don't see where any conversion is coming in.I had changed the name a little bit as it used to a (, ) and a : in the GUEST_NAME. I thought that might be causing the issue so I removed them with a REPLACE through an UPDATE query. However, the record still needs to be deleted.
It should be a simple query as it happens on this table all the time, so I don't know why this one is different.
I am trying to install and create an oracle 11gR2 database on windows 7 platform. Do we need to run exceed software while we create the database? I heard that we need exceed for unix and unix based servers. But do we need it for windows OS? While installing the oracle software, the DBCA could not startup. It didnt give any error, but it couldn't startup. I am unable to download exceed software in my office machine due to security reasons. Is there any other alternative so that I could complete the oracle installation along with creating the database successfully?

Is there any way I can execute this query w/o having to break the 'IN' list up by 1,000 Acct_Num over numerous amount of times? I know the 50,000+ accounts I want the info on but they are not ordered and they mix ranges with accounts I don't want. Therefore I can't use a 'BETWEEN' clause. Also, I don't have the ability to create a temp table.
I'm currently doing migration from Oracle 10gR2 RDF to Oracle 11gR2 Semantic Technology.I followed the steps on the documentation and successfully created the network using the following:
-----
EXECUTE SEM_APIS.CREATE_SEM_NETWORK('rdf_tblspace');
CREATE TABLE rdf_network_trace (id NUMBER, triple SDO_RDF_TRIPLE_S);
--Created SEQUENCE andTRIGGER FOR rdf_network_trace id
[code]....
when I looked at my Node Ids, they were like +635762253807433724+, +6118969225776891730+. The problem is, I am not the one who is assigning Node Ids, They were automatically generated when inserting TRIPLE data to the rdf table.
Did I miss something when I created my network?
I have an Oracle Database 11gR2 installed on Windows 2008 server. But there is a kind of hang sometimes arise during work hours. while i am opening control panel i saw oracle process is around 15G even we configured SGA_MAX_TARGET=6g.
View 2 Replies View RelatedI am trying to understand how to enable some audit so we can capture OEM logins as well.
Here is my setup. Lets say my DB that i am auditing is called audit_db (audit trail set to DB) sitting on host called host_db. and we have grid control agent on this box.now my grid control is as this. Lets say my OMS and repository is on host called OMS_host.
we run query aginst dba_audit_session to get info as to who tried failed login attemps and stuff.
Now to the part that is not working.
-- this is the good part When i intentionaly login to the audit_db with sqlplus client from my laptop with wrong username/password that is captured. we get the username,os_username,userhost,terminal.
here is the sample output
username is the wrong user that i tried to login as
os_username is the my local username(ad account)
userhost is my_laptop_name
terminal is laptop_name
from above we can figure who was trying to login(failed).
-- this is the bad part But lets say i try to login to audit_db through grid control and use wrong username/password.that gets captured too(but not all of it). we get the username,os_username,userhost,terminal.
here is the sample output
username is the wrong user that i tried to login as
os_username is the user of OMS repository db(oracle)
userhost is oms_host
terminal is unknown
Now with the above info, we cannot figure out who tried to login with bad login credential.
Any documentation supporting Oracle 11G and Advanced Security stating encryption at rest is FIPS 140-2 compliant?
View 3 Replies View RelatedLost Windows password? Forgot Windows password? Your PC was hacked? Therefore, it is a basic step for every Windows users to enhance the security of Windows password. In the networks, it is found that a number of user's passwords are easy to guess. Only the smallest groups are the most security conscious and select passwords that are mixed lowercase and uppercase letters, numbers and punctuation to create cryptic passwords. Adopting strong password is one of the most effective ways to ensure system security. Here are several methods for you to enhance the security of your passwords in Windows 7/2000/XP/Vista and so on. You'd better remember the methods below unless you want to reset Windows password from time to time.
1. Is random password a great password?
A common myth is that totally random passwords like Ht3&e#L%5d@$B are the best passwords. This is not true. While they may be strong passwords, they are usually difficult to remember, slow to type, and sometimes vulnerable to attacks against the password generating algorithm. It is easy to create passwords that are strong but much easier to remember by using a few simple techniques. For example, consider the password "Luck-73@Better?". This password utilizes uppercase and lowercase letters, two numbers, and three symbols. The password is 15 characters long and can be memorized with very little effort. Moreover, this password can be typed very fast. The portion"Luck" and "Better" alternate between left and right-handed keys on the keyboard, improving speed, decreasing typos, and decreasing the chances of someone being able to discover your password by watching you.
2. Create the long Windows password
Although a password may eventually be discovered through some means, it is possible to create a password that cannot be cracked in any reasonable time. If a password is long enough, it will take so long or require so much processing power to crack it. That is essentially the same as being unbreakable (at least for most hackers).
3. Create the Windows password constantly?
This may be good advice for some high-risk passwords, but it is not the best policy for every user. It is frustrating for a user to have to constantly think of and remember new passwords every 30 days. It may be better to focus on stronger passwords and better user awareness rather than limiting password age. A more realistic time for the common user may be 90-120 days.
4. Write down Windows password in a proper place
Sometimes it is necessary for some users losing and forgetting complex passwords easily to write down them somewhere proper. However, it is important to educate users on how to write down passwords properly. Obviously, a sticky note on the monitor is not a good idea, but storing passwords in a safe or even a locked cabinet may be sufficient.
5. 14 characters is the optimal password length
Each character that you add to your password increases the protection. Your passwords should be 8 or more characters in length; 14 characters or longer is the Optimal Password Length. Many systems also support use of the space bar in passwords, so you can create a phrase made of many words. It is not easier to forget and lose, as well as longer than a simple password, and harder to guess.
6. Try not to use the same Windows password for all accounts
Some users always make the same passwords for every account to make it easy to remember. In that case, when any one of them lost, your other information protected by that password will be in danger as well. It is serious to use different passwords for different systems and accounts.
7. Do not use some common words that other users maybe guess
Most of users prefer to use some common words to remember easily, for example, login name, birth date, driver's license, passport number, pets' name and other words contained their personal information someone knows. In that case, your Windows system will not be safe anymore. Moreover, do remember not to use some words spelled backwards, abbreviations, sequences or repeated characters and adjacent letters, such as, asdfgh, 123456, 888888, abcdef and so on.
You can smoothly use your Windows now because the strong and powerful Windows password is created successfully, Certainly, I believe that many users lost Windows password and forgot Windows password, then you need have to reset Windows password or recover Windows password. It is a big problem for plenty of Windows users that how to reset Windows password. how to recover Windows password and they are puzzled by resetting windows password, for instance, reset Windows 7 password, recover password Windows XP, remove Windows Vista password and other operating systems after they create the password with complex letters, numbers and symbols. However, it is unnecessary to worry and it is said that things will eventually sort themselves out. There are many ways to reset forgotten Windows password, including use windows password reset disk and windows password reset software, like Super Windows Password Reset, a professional windows password reset software which could enable you to logon to Windows smoothly without reinstalling system.
In Sybase, my application was using system tables to perform application login security. Those tables obviously don't exist in Oracle. I am looking for ways to provide the following functionality in an Oracle world:
1. How to determine 'x' days of inactivity based on "last login date"?
2. How to determine when a new user logs in for the first time and force them to change their password?
3. If we need to reset a users password, how can we require the user to change their password?
4. Is there any other option other than storing a user-id/password in the application code for locking a user's account if their account needs to be locked due to inactivity?
5. In the USER_USERS view there is a status column. What the different status's can be?
Provide me the script which would track all the users security violations like ... say for example i want to find which users logged in and what he did in database prospective.

I'm having some issues with my NVarchar2 columns that I want to solve
My current NLS_CHARACTERSET is 'AL16UTF16', and therefore I can only create NVarchar2 columns with an maximum extension of 2000 bytes. But I do need a column with 4000 bytes length. How can I create an 4000 NVarchar2 column?
(I do not want to use a CLOB column...only a NVarchar2)
I want to create a table with a length greater than 30.I Thought there was a way to override the max length for for a table name in Oracle 11.2.0.2.I cant find a documentation that states how to get it done.
