Question

How to login in after installing Oracle 10G?

Asked by: a_anis3000

I am totally new to Oracle and I am trying to figure out how to login after installation. I installed Oracle 10G Release 2, using basic installation and default account (user name orcl). But I am now unable to log in neither SQL *Plus nor the browser based "Oracle Enterprise Management". Whenever I attempt to login in SQL* Plus I get a "ORA-01017: invalid username/password; logon denied ".

I double checked the username and password that were provided in the installation phase and I am sure they are correct, yet I still get the same error message.

However I managed to login in SQL *Plus through scott account by enabling it following the steps in this thread

http://kr.forums.oracle.com/forums/thread.jspa?threadID=666776

it worked, however it doesn't in the Oracle Enterprise management, attempting to login in with the scott account yeilds a "The application requires more database privlidges than you have currently been granted".

You didn't say which Oracle user you are trying to login as.

orcl is not a default Oracle user.

The standard DBA users are SYS and SYSTEM, those are the users that are set with the password from the installation.

As far as the message when you try to login to OEM as SCOTT, a standard user needs to be granted "SELECT ANY CATALOG" or "SELECT_CATALOG_ROLE" to login via OEM. So when you do finally login as a DBA, do the grant:

SQL> grant select any catalog to scott;

>>You didn't say which Oracle user you are trying to login as.<<
Excuse the ignorance of my question (I am totally new to oracle) but how do I know what user I am logged in as?

>>The standard DBA users are SYS and SYSTEM, those are the users that are set with the password from the installation.<<

Based on that information I tried to log in with user name SYSTEM and using the password that I provided during the installation in SQL *Plus and Oracle Enterprise Management. it seems to work in both so far.


>>As far as the message when you try to login to OEM as SCOTT, a standard user needs to be granted "SELECT ANY CATALOG" or "SELECT_CATALOG_ROLE" to login via OEM. So when you do finally login as a DBA, do the grant:<<

I tried to type in the SQL*Plus the command you mentioned which is

SQL> grant select any catalog to scott;

however it yields the following message

Error at line 1:
0RA-00990: missing or invalid priviledge

>>Excuse the ignorance of my question (I am totally new to oracle) but how do I know what user I am logged in as?

It is the user you provide at the SQLPLUS command line. Example:

  sqlplus system/pass


But it appears you have successfully logged in as SYSTEM now. Be aware that as long as you have access to the Windows or UNIX user that owns Oracle, you can use that user to access Oracle without a password. Usually we name the OS user "oracle". The "oracle" user can simply do:

  sqlplus / as sysdba

Which connects you as SYSDBA and you can do anything, including change the password.


>>SQL> grant select any catalog to scott;

Oops. My memory is playing tricks on me. It is "select any dictionary"

SQL> grant select any dictionary to scott;

 

by: a_anis3000Posted on 2009-10-18 at 07:12:21ID: 25599919

>>SQL> grant select any dictionary to scott;

Thanks now I am able to log in both SQL* Plus and Oracle Enterprise Management with the scott account

two more things

Attempting to login with the SYS account would yield the following error message

Error
ORA-28009: Connection as SYS should be as STSDBA or SYSOPER

Its not a big deal since I can already login with other account but I suppose it's good to know the reason behind this error message

Also as far as I know its recommended to use your own account to log in Oracle rather than tyhe default accounts, so I was wondering how to create one, and how to give it administrative privileges like the one with the SYSTEM account.

Thanks again in advance

sqlplus / as sysdba

That connects you as SYSDBA (and you are effectively SYS)

The 2 command version:

SQL> create user mydba;
SQL> grant dba to mydba;


Or the shortcut to create and grant in one pass:

SQL> grant dba to mydba identified by mypass;
