I have created a user, let's call him C##USER from sysdba. Now, I'm trying to create another user from C##USER. Problem is I keep getting the following error:
ORA-01031: insufficient privileges
I have granted C##USER all privileges and have set the default role to ALL. Nothing works yet...
Any ideas? Thanks in advance.
You just need a CREATE USER system privilege BUT don't forget to use CONTAINERclause which should be set to ALL, if you omit this clause then the grantee will have CREATE USER system privilege on the current container.
Specify CONTAINER = ALL to commonly grant a system privilege, object privilege on a common object, or role, to a common user or common role
GRANT
When a common user account is created, the account is created in all of the open pluggable databases. So the user who is creating this new user must have CREATE USER system privilege on all containers.
SQL> grant create user to c##user container=all;
Grant succeeded.
SQL> conn c##user
Enter password:
Connected.
SQL> create user c##user2 identified by user2;
User created.
I granted CREATE ANY TABLE privilege to allow another user to create tables for my user. Ok. That worked. I want to allow this same user, after they created the table, to grant select privilege to public. But the Oracle says: insufficient privileges.
How can I grant select privileges to a table I have just created?
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;

First step:
Connect to a database using System/Password;
second Step:
create user username identified by password; (syntax)
Ex: create user manidb idntified by mypass;
third Step:
grant connect,resource to username; (Syntax)
Ex: grant connect,resource to manidb;
step 1 .
create user raju identified by deshmukh;
step 2.
grant connect , resource to raju;
step 3.
grant unlimitted tablespace to raju;
step4.
grant select , update , insert , alter to raju;
I'm using Oracle XE but I would like to log in as a user than can create tables, contraints etc., but who cannot view all of the other system tables and stuff that you see when you log in with the system account.
How can I achieve this?
You need to create a new user with:
CREATE USER xxx IDENTIFIED BY yyyy;
From there, issue GRANT for the privileges you want to give the user:
GRANT CREATE SESSION TO xxx;
GRANT CREATE TABLE TO xxx;
GRANT CREATE VIEW TO xxx;
etc.
See the SQL Reference documentation for all the privileges you can grant. User xxx will only be able to see their own objects and objects they have been granted privileges on.
I have created a database in Oracle. Say "TEMP" is the name of the database created. I have created a user DWH. Now I would like to grant access to TEMP for the user DWH.
How shall i do?
. When you say you have created a user DWH do you mean at operating system level or database level ?If you have created a database user
Anyway the command for creating a user in database is
create user DWH identified by password;
Now if you want to be able to connect to database and create a table you need the following
grant create session to DWH;
alter user DWH default tablespace users quota 100m on users;
grant create table to DWH;
You can grant other permissions also.You can also group permissions into a role and grant the role.
