Security :: User Unable To Login After Password Reset

Dec 14, 2011

We have a production database on version. The application user was prompted to change the password after his password expired.

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.

Application Express :: Oracle 11g XE - Retrieve Or Reset Password

Dec 12, 2012

I cannot remember my password to access an existing database in Application Express. I tried entering my password 3 times, but the system does not provide a status other than 'Invalid Login Credentials'.

I am going to assume that 3 times is limit before you have to reset the password or from what I see reinstall. When selecting reset, the system asks for an email address that was never established in the system. How can I reset my password without uninstalling and reinstalling Oracle 11g XE?

Security :: Enhance Security Of Windows And Recover Lost / Forgotten Password?

Nov 16, 2010

Lost 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.

Possible To Specify Login / Password For DBLINK When Calling It?

Apr 3, 2013

I have a Oracle 91 database running on Windows 2003 with a DBLINK setup to connect to an external client. I'm looking at how i can setup a quick job that, say every 5 mins, runs a query over the DBLINK and if it returns data, then success. If it returns an error, then the DBLINK is down, moreso the external server, and then fire off an email to someone.

However, this DBLINK i think was created to be used by a specific username/password. When i try to run a query against it using SYS, i get invalid username/password error.

So is there a way i can use a DBLINK and specify the username/pwd to be used at runtime? I'm new to Oracle database..Something like 'select * from global_name@DBLINK1 as username/pwd'.
