when i created the IDs, i set up passwords in JAVA.
i couldn't log in SQL DEVELOPER and i got a error message, ORA-01017.
i tried to enter the password of lowercase and uppercase.
i tried to change the passwords.
SQL> alter user java identified by java;
succeed
SQL> alter user java identified by java11;
succeed
but...... because of same problem, i couldn't log in.
how can i do to solve this trouble?
my oracle is 11g.

I'm attempting to run the following command as I am trying to get logminer to log my database. When I run the following command, I get a response of Insufficient Privileges
ALTER DATABASE ADD SUPPLEMENTAL LOG DATA;
I have to run it as a specific user, so I need to know what Granted Roles and/or System Privileges are required to run this statement.
I'm not a DBA (and stuff like that are supposed to be run by DBA), but: privileged user should grant you (as you said that you'll be running it yourself) the ALTER DATABASE privilege:
scott is just a poor user:
SQL> show user
USER is "SCOTT"
SQL>
SQL> alter database add supplemental log data;
alter database add supplemental log data
*
ERROR at line 1:
ORA-01031: insufficient privileges
A privileged user is SYS (if you don't have any other):
SQL> connect sys as sysdba
Enter password:
Connected.
SQL> grant alter database to scott;
Grant succeeded.
Back to scott, re-run the statement:
SQL> connect scott/tiger
Connected.
SQL> alter database add supplemental log data;
Database altered.
SQL>
That's the minimum. You could have also granted the DBA role to scott, with the same effect (regarding this very statement, but - DBA is much more powerful):
To illustrate it, revoke the privilege first:
SQL> connect sys as sysdba
Enter password:
Connected.
SQL> revoke alter database from scott;
Revoke succeeded.
Does it still work? Of course not:
SQL> connect scott/tiger
Connected.
SQL> alter database add supplemental log data;
alter database add supplemental log data
*
ERROR at line 1:
ORA-01031: insufficient privileges
Grant DBA role:
SQL> connect sys as sysdba
Enter password:
Connected.
SQL> grant dba to scott;
Grant succeeded.
Does it work now? Yes, it does:
SQL> connect scott/tiger
Connected.
SQL> alter database add supplemental log data;
Database altered.

I am trying to login to oracle sqlplus using system/manager but unable to do.
I logged in using sys user and then ran
ALTER USER SYSTEM IDENTIFIED BY manager;
It said user changed but then when I did
CONN SYSTEM/manager
It says invalid login/password.
Please tell me what I am doing wrong
make sure the sec_case_sensitive_logon parameter set to false
Please, post your SQL*Plus session which shows what exactly you did and how Oracle responded - just like in my example:
SQL> show user
USER is "SYS"
SQL> alter user system identified by manager;
User altered.
SQL> conn system/manager
Connected.
SQL>
whenever I'm trying to connect with scott it is showing invalid username/password,
tried this:
alter user scott account unlock;
SP2-0640: Not connected
alter user scott identified by tiger;
SP2-0640: Not connected
Go to the Installing path of the Oracle 11g In default it is present C: Drive, then move to C:\oraclexe\app\oracle\product\11.2.0\server\rdbms\admin
here you can find a file named scott.sql
Open the SQL Command Line and login as conn system/ (password set during the installation of oracle 11g)
Run the Below script (Note: File name is appended at the end)
# C:\oraclexe\app\oracle\product\11.2.0\server\rdbms\admin\scott.sql
Now you can query the SELECT * FROM all_users; to see the scott schema created
Alternatively you can do this by using SQL developer by creating a connection to SYSTEM and run the above script
After the creation the default username : SCOTT password: TIGER
In the comment part i especially asked for querying
select count(1) from dba_users where username = 'SCOTT';. I'd like to learn if user exists.
For the message you get ORA-01017,
the First possible reason is what message tells us(invalid
username/password).
Secondly, you may not have an account named SCOTT. i.e. the above
query gives 0(zero).
In this case :
you should create mentioned user ( when you're connected to system ):
SQL> conn system/pwd
Connected.
SQL> create user scott identified by tiger;
and grant related privileges :
SQL> grant connect to scott;
SQL> grant resource to scott;
and then you can connect by issuing :
SQL> conn scott/tiger
Connected.
Connect with a DBA Account and Issue an Alter User Command
The error you are seeing indicates you are no longer connected to the database. You were logged in as system#db, but when you tried to connect as scott#db, you no longer have a database connection.
Here I replicate your experience:
SYSTEM#db>conn system#db as sysdba
Enter password:
Connected.
SYS#db>conn scott#db
Enter password:
ERROR:
ORA-01017: invalid username/password; logon denied
#>alter user account scott unlock;
SP2-0640: Not connected
#>alter user scott identified by tiger;
SP2-0640: Not connected
Here I reconnect and then issue an alter user command to unlock the user account and set a new password.
#>conn system#db as sysdba
Enter password:
Connected.
SYS#db>ALTER USER scott IDENTIFIED BY tiger ACCOUNT UNLOCK;
User altered.
SYS#db>conn scott/tiger#db
Connected.
Addendum
My steps provided assumed you had the scott schema installed. If the scott schema does not exist, it would be good to see if the default 11g database sample schemas exist.
The schema account scott is no longer a default schema in the 11g database. The 11g documentation states:
"Oracle used the schema SCOTT with its two prominent tables EMP and
DEPT for many years. With advances in Oracle Database technology,
these tables have become inadequate to show even the most basic
features of Oracle Database and other Oracle products. "
I would recommend reviewing to see if the other default sample schemas are installed. The hr account is most similar to the scott schema.
Here is a list of common sample schema usernames:
username IN (
'HR',
'OE',
'PM',
'SH',
'IX'
)
Check to see if the person whom performed the installation used the database configuration assistant and opted to install the sample schemas.
If the schemas were not created at the time of installation, the document, "Oracle® Database Sample Schemas 11g Release 1 (11.1) B28328-03", describes the steps to do this in chapter 2, Installation.
Open Oracle sql developer.
In the sql developer paste the path of scott.sql file(C:\oraclexe\app\oracle\product\11.2.0\server\rdbms\admin\scott.sql) with '#' infront of it.
# C:\oraclexe\app\oracle\product\11.2.0\server\rdbms\admin\scott.sql
Run script
Script Output -> Connection created by CONNECT script command disconnected
Connect using SQL Command Line
conn scott/TIGER;
Can someone advise me on how to create a user in Oracle 11g and only grant that user the ability only to execute one particular stored procedure and the tables in that procedure.
I am not really sure how to do this!
Connect as SYSTEM.
CREATE USER username IDENTIFIED BY apassword;
GRANT CONNECT TO username;
GRANT EXECUTE on schema.procedure TO username;
You may also need to:
GRANT SELECT [, INSERT] [, UPDATE] [, DELETE] on schema.table TO username;
to whichever tables the procedure uses.
Follow the below steps for creating a user in Oracle.
--Connect as System user
CONNECT <USER-NAME>/<PASSWORD>#<DATABASE NAME>;
--Create user query
CREATE USER <USER NAME> IDENTIFIED BY <PASSWORD>;
--Provide roles
GRANT CONNECT,RESOURCE,DBA TO <USER NAME>;
--Provide privileges
GRANT CREATE SESSION, GRANT ANY PRIVILEGE TO <USER NAME>;
GRANT UNLIMITED TABLESPACE TO <USER NAME>;
--Provide access to tables.
GRANT SELECT,UPDATE,INSERT ON <TABLE NAME> TO <USER NAME>;
The Oracle documentation is comprehensive, online and free. You should learn to use it. You can find the syntax for CREATE USER here and for GRANT here,
In order to connect to the database we need to grant a user the CREATE SESSION privilege.
To allow the new user rights on a stored procedure we need to grant the EXECUTE privilege. The grantor must be one of these:
the procedure owner
a user granted execute on that procedure with the WITH ADMIN option
a user with the GRANT ANY OBJECT privilege
a DBA or other super user account.
Note that we would not normally need to grant rights on objects used by a stored procedure in order to use the procedure. The default permission is that we execute the procedure with the same rights as the procedure owner and, as it were, inherit their rights when executing the procedure. This is covered by the AUTHID clause. The default is definer (i.e. procedure owner). Only if the AUTHID is set to CURRENT_USER (the invoker, that is our new user) do we need to grant rights on objects used by the procedure. Find out more.
Don't use these approach in critical environment like TEST and PROD. Below steps are just suggested for local environment. For my localhost i create the user via these steps:
IMPORTANT NOTE : Create your user with SYSTEM user credentials.Otherwise you may face problem when you run multiple application on same database.
CONNECT SYSTEM/<<System_User_Password>>#<<DatabaseName>>; -- connect db with username and password, ignore if you already connected to database.
Then Run below script
CREATE USER <<username>> IDENTIFIED BY <<password>>; -- create user with password
GRANT CONNECT,RESOURCE,DBA TO <<username>>; -- grant DBA,Connect and Resource permission to this user(not sure this is necessary if you give admin option)
GRANT CREATE SESSION TO <<username>> WITH ADMIN OPTION; --Give admin option to user
GRANT UNLIMITED TABLESPACE TO <<username>>; -- give unlimited tablespace grant
EDIT: If you face a problem about oracle ora-28001 the password has expired also this can be useful run
select * from dba_profiles;-- check PASSWORD_LIFE_TIME
ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED; -- SET IT TO UNLIMITED
As previously mentioned multiple times in the comments, the use of the CONNECT, RESOURCE and DBA roles is discouraged by Oracle.
You have to connect as SYS to create your role and the user(s) which are given this role. You can use SQL Developer or SQL*Plus as you prefer. Do not forget to mention the SYSDBA role in the logon string. The connect_identifier uses different syntaxes.
sqlplus sys/<<password>>#<<connect_identifier>> as sysdba
Let's say you have a 12cR1 like the one provided as a VM with the "Oracle Technology Network Developer Day". The connect strings might be (to connect to the provided PDB) :
sqlplus sys/oracle#127.0.0.1/orcl as sysdba
sqlplus sys#"127.0.0.1/orcl" as sysdba -- to avoid putting the pw in clear
Note that under Unix, the quotes have to be escaped otherwise they will be consumed by the shell. Thus " becomes \".
Then you create the role MYROLEand grant it other roles or privileges. I added nearly the bare minimum to do something interesting :
create role myrole not identified;
grant create session to myrole;
grant alter session to myrole;
grant create table to myrole;
Next your create the user MYUSER. The string following identified by which is the password is case-sensitive. The rest is not. You could also use SQL delimited identifiers (surrounded by quotes ") instead of regular identifiers which are converted tu uppercase and subject to a few limitations. The quota could be unlimited instead of 20m.
create user myuser identified by myuser default tablespace users profile default account unlock;
alter user myuser quota 20m on users;
grant myrole to myuser;
Eventually, you connect as your new user.
Please note that you could also alter the default profile or provide another one to customize some settings as the expiration period of passwords, the number of permitted failed login attempts, etc.
CREATE USER USER_NAME IDENTIFIED BY PASSWORD;
GRANT CONNECT, RESOURCE TO USER_NAME;
CREATE USER books_admin IDENTIFIED BY MyPassword;
GRANT CONNECT TO books_admin;
GRANT CONNECT, RESOURCE, DBA TO books_admin;
GRANT CREATE SESSION GRANT ANY PRIVILEGE TO books_admin;
GRANT UNLIMITED TABLESPACE TO books_admin;
GRANT SELECT, INSERT, UPDATE, DELETE ON schema.books TO books_admin;

I have installed Oracle 11g on Windows 7
When I start sqlplus, it ask me for a username and password
Can anybody tell me what username needs to be inserted and when I try to type in any password, it doesn't allow me to type a single letter. Is there a reason why?
If you've forgotten the password for any user then you can reset by logging in as SYS:
sqlplus / as sysdba
And then:
alter user <username> identified by <password>;
If you've forgotten which users you have then you can run:
select username from all_users;
If you have only recently created the database it would be worthwhile restricting on CREATED, as the default database install comes with dozens of its own schemas. For instance, to find users added in the last week run this:
select * from all_users
where created > trunc(sysdate)-7;
Enter SYSTEM as user-name and the password entered during installing 11g works well for me!
The username refers to the schema to which you must connect to. Generally the hr schema is the sample schema that is available. The password will be the same password that you set during Oracle installation.
