Hello

I think this will be a really simple post for someone.

I downloaded oracle and installed it on my pc about 4 months ago for uni - We are now revisiting the suject.

I booted up forms designer and then wanted to run an sql script - however I cant even remember what my username or password is for connection - How can i retrive this - are there any standard ones?

Please help- thanks

    Well the usernames are shown in the dba_users's username column. You can see from there that which user was created and you can use it. For the passwords, there is a password colunm in the same view but its encrypted so you wont be getting any benefit from it. What I suggest is that you use , "alter user username identified by password" command and change the password of that user.

    " How can i retrive this - are there any standard ones?"
    In case you selected some sample schemas to be installed during the db installation there is , at least one:
    username SCOTT , password TIGER

    Buy a book and start reading. You can also browse through the documentation instead of installing this stuff and expecting people to give you "how do I connect 101" lessons.

    Hang on a minute mate

    Im a total novice at this subject and I am needing help - hence comming onto this forum.

    I have read through some documentation - If you actually read the issues i have posted on this site they do not comply with oracle documentation:

    My system needed to increase vitual memory/paging files in my firts post
    I cant remember user name password - i have looked for this and find nothing!!

    So sorry for wasting your presious time - im just glad other people help out instead of idiots like yourself

    Hey no need to be sorry mate.Its a tech discussion between two professionals and its no crime when one doesn't know about some thing. I too don't know anything about Oracle so chill :-).
    Well about your error, you are on the server or on a client? If you are on a client, you need to supply the right username and password wth a right service name to connect to the server. If you are on the server than you can come to the command prompt of the server o/s and issue the commands that I gave you.
    Scott/tiger should work provided that schema was created when the db was installed.

    Ok, you have lost your Username and password.

    You can enter a sqlplus session with sysdba privileges and reset the password.

    1. Connect as sysdba from the command line:

    sqlplus / as sysdba

    2. Once you are in a sqlplus prompt issue the reset command:
    SQL> alter user scott identified by tiger account unlock;

    It all depends on which user you are unlocking. If you created a default database, then you have several other demo accounts which remain locked, HR, SH, OE, PM.

    If you require a new account, then you must create a new user. Look for the CREATE USER command to accomplish this task.

    I am sorry to say, but that's the reason why you are asked to read Oracle document. if you have difficult to understand how to run sqlplus and login as sysdba. Then that implies you didn't spend your time do your due diligent to understand some basis of Oracle administration.

    Of course someone might willing to spend time baby feed you with the command and SQL but without knowing your environment that's not very efficient way to learn and get things done correct ?
