I have been working on Oracle 11g expression edition from around 2-3 month. But today I was trying to login to the workspace but every time it is showing as invalid credentials. But I the workspace name and password entered by me are right even I have saved on chrome.
So how can I recover my workspace account?
A "workspace" - in this context - seems to be related to Oracle Application Express. Is it?
If so, login as admin into the internal workspace (presuming, of course, that you know admin's password), and then you can reset any other developer's password - including your own.
If you don't know admin's password, there's another option; it presumes that you a) know SYS user's password and b) have the apxchpwd.sql script available (you do, if you installed Apex; search the disk). Then connect to SQL*Plus and run the named script, e.g.
C:\>sqlplus sys#xe as sysdba
SQL> #apxchpwd.sql
Once you set admin's password, back to suggestion #1: login as admin (into Apex) and set users's password.
If nothing of that helps (or you don't know any of those passwords), then you're pretty much out of luck, as far as I can tell.

I just downloaded the Oracle Database 11g and I can't select,create,update or do anything. Every command that I entered and run only results to "ORA-01435: user does not exist"
What are the things that i need to do in order to enable creating and running some commands?
Here is a picture of ORA-01435: user does not exist
Please look at right upper corner SCHEMA:XS$NULL:
From Securing Oracle Database User Accounts
XS$NULL
An internal account that represents the absence of a user in a session. Because XS$NULL is not a user, this account can only be accessed by the Oracle Database instance. XS$NULL has no privileges and no one can authenticate as XS$NULL, nor can authentication credentials ever be assigned to XS$NULL.

You need to change it to some specific schema.
I have a pluggable database in Oracle 12c named PDBORCL.
After a server restart something changed in how to connect to it.
I created a user in that pluggable DB, for the example the user is PETER and the password is also PETER. Before the restart I used to be able to open a Command Prompt, run sqlplus, which would in turn ask for my username and then its password, and it would sign in. Now this does not work, it says invalid username/password. When I log in with SYS and check:
SELECT * FROM dba_users WHERE username = 'PETER';
I get no results.
However, if I sign in using the following from a command prompt, it works:
sqlplus PETER/PETER#PDBORCL
So, the DB is up and running, but it seems to be connecting by default to the wrong pluggable DB. I need to change it to the way it was before the restart, so that it connects by default to that specific pluggable DB.
How can I achieve this?
I found the solution. Change or create the environment variable LOCAL (in Windows) to PDBORCL. I think I read in linux the variable is TWO_TASK. After changing it, the following works:
sqlplus PETER/PETER
Also, just calling sqlplus and waiting to be prompted for username and password works.
You have created a user in pluggableDB and this user is not visible beyond the pluggable DB hence the reason you dont see user PETER when running the above query as sys..
If you want to connect to your pluggable DB directly what you have done above is right else you to connect to sys and the use CONNECT command.
My company has a database for vehicle tracking system. And It has a website for user to log on and use.
After I change the sys and the main user password through "ALTER USER --- identified by' command. The website login became dysfunctional. Our DBA just quit so I have no idea how to troubleshoot.
Is there any guideline I can use?
It appears as though the application has the passwords either hardcoded or in a configuration file somewhere. If you can find where that is, then simply changing the corresponding values (ie passwords) should resolve the problem. If that doesn't work, you can try to change the password back to the what they were before using the same syntax you used to make the initial change ... "ALTER USER --- identified by ...
Can possibly be more help if you can tell what web server is hosting your site.
I'm just getting started with Oracle data export and import and things worked perfectly fine the first time around. But then I came back next day repeated the exact same steps on the same systems, but get ORA-01435: user does not exist error.
System Specs for all machines:
-OS: Windows 2012 R2 x64
-Oracle Server: Oracle 11G Express x64
Objective:
I'm exporting data from Oracle server 1 and importing to Oracle server 2.
Procedure:
Export data dump is successful from Oracle server 1.
but when importing the data dump on Oracle server 2, I follow this procedure:
-Stop IIS service
net stop WAS
Create Schema/user account and Grant privileges before import
net stop WAS
sqlplus / as sysdba;
CREATE user PIE1 identified by PASS1;
GRANT ALL PRIVILEGES TO PIE1;
GRANT IMP_FULL_DATABASE TO PIE1;
According to oracle, all goes well, but look at the first image bellow. In DBeaver, I can see that only the User account PIE1 has been created, but NO schema.
Oracle issue 1. User account created, but not the Schema
Question 1: According to Oracle, the command "Create User" IS supposed to also create an associated Schema. Anyone have an idea why this is no longer working for me? It worked once the night before.
I then continue the import procedure as follows:
imp PIE1/PASS1#xe file=c:\Backups\AVUSER2_6_7.dmp log=c:\Backups\import.log fromuser=AVUSER2_6_7 touser=PIE1;
But get the following error:
Oracle claims the User doesn't exist even though it does
Oracle claims the User doesn't exist even though it does. I repeated the entire procedure and even created an identical import/export user account and credentials, and this error still comes up.
Question 2: Any idea why Oracle "Can't find" a user account that's clearly in the database?
Additional Info:
Checked that my windows account is in admin group
Checked that my windows account is in ORA_DBA group
Opened all CMD prompt as Admin
As you implied, users and schemas as the same in Oracle, you can't have a user without a schema. No idea about DBeaver, but as there are other users that aren't listed under 'schemas' (according to your second image - ANONYMOUS, DIP, ...) that seems to be unrelated.
(Purely a guess, but perhaps the user you're connect as in DBeaver just doesn't have visibility of any objects owned by those users - maybe it only lists users it can see in all_objects, say. Pure speculation, but you could investigate that by looking at the data dictionary while connect through SQL*Plus as the same user. According to this old forum post, there is an option to hide empty schemas...)
The import is connecting successfully as PIE1 - you'd get a different error, ORA-01017, if it wasn't and you wouldn't see the 'Connected to...' banner or anything after that.
Your import command has a trailing semicolon that should not be there. The "importing ... objects into" message shows that it's trying to import into the PIE1; user and not the one you actually created, PIE1. Remove that semicolon and try again.
Incidentally, you can probably also remove the #xe TNS alias and stick to a local connection, assuming the environment is configured as it was whenyou ran SQL*Plus. You should also consider using datapump expdp/impdp rather than the legacy exp/imp.
I am newbie to oracle sql developer 3.1.07.42, and have just installed it on my machine. I want to make a new connection, but it requires a user and a password which I do not know. I have been googling about it since many days, and have learned that there are some commands to create user, but I do not know where should I run those commands, because I cannot run queries/commands until the connection is created.
Would anyone let me know what should I do?
Steps for creating new user :
1)Open Sql Developer, make new connection.
2)Login with System username and password(made during installation).
3)Once you connect, expand the System user (under Connections, in the left pane) and scroll down to Other users. Then right click users and add new user.
4)Give its username and password & select appropriate system privilege.
5)You are done now, check by making new connection.
Use this below simple commands to create an user
-- Create a user
CREATE USER youruser IDENTIFIED BY yourpassword;
--Grant permissions
GRANT CONNECT, RESOURCE, DBA TO demo;
you should install database software in your local pc/laptop then create user in the database and you can connect the database via sql developer by key in username and password that already created.If you want to connect to other database same step like the previous step but before that you need to point to the remote database.
I thinks you should use "Database Configuration Assistant" to create new database and U can set user name and password and use it in oracle SQL Developer!!!
