I forgot sys and system password

Dear All,
I installed oracle database 9.2.0.6 one year ago and I am using this database for RMAN.
Today I need it to do something else but I really forgot the sys and system password and i dont know what to do.
I appreciate your help on that.
Thanks

Hi,
>>I really forgot the sys and system password
Really ? or are you trying to hack the database ? :-)
You can try this too:
Use the orapwd utility in order to re-create the SYS password...
e.g.: orapwd file=orapw<SID> password=adm entries=5
Cheers

Forgot SYS and SYSTEM password

Hi all,
I have forgotten the password for SYS and SYSTEM. Is there any way to reset their pwd?

It depends on what authentication you use
IF you have something like remote_login_passwordfile=NONE then it will be OS authentication in that case
you can use
cmd>sqlplus "/ as sysdba"
login to sqlplus change the password
If toy have something like remote_login_passwordfile=SHAREDor EXCLUSIVE then
frm cmd>orapwd file=<name> password=<pwd> entries=5
will do that for you
Correct me if i am wrong

Starting up a database when I forgot the sys and system password

Hi,
I want to startup up a database from Oracle Entreprise Manager. I forgot the sys and system password.
If I give the command:
orapwd file=orapwSDB01 password=test entries=100
can I give the password "test" to sys and then to connect with sys with password test as sysdba, and then to startup the database? Are any problems with this command?
Thank you,
Mihaela

Hi,
I have not done this myself, but YES, according to the documentation, thats correct.
ORAPWD FILE=mypwdfile PASSWORD=syspass ENTRIES=10
will set the password of SYS to syspass. And you can use the same further.
But here, you should be in oracle user or the user which owns the Oracle installation.
Also, OS authentication is always supperior than any other authentication.

Lost of sys and system password

Hello,
What are the options when the sys and system passwords to 9206 on Windows 2000 are not known. I was given the database but no one knows the passwords to sys and system. The Windows o/s account does belong to the DBA group but I am not able to log on as '/ as sysdba'. Error saids insufficient privilege even though the o/s acct belongs to group DBA. What can be done to gain access so sys and system passwords can be reset. Thank you in advance.

Hi, please review the Note:77665.1 into metalink site.

Importing full database and SYSTEM password

Hi,
I have a export dump of a database (full database dump). Want to import on my existing database.
I have create a database, with tablespaces matching names with source database (i.e. got a list of tablespaces from the dba of source database and created them). Now, I am ready to import with imp command (with FULL=Y option).
Will the full database import change my SYSTEM's password to the system's password on the source database ?
Reason for this question is, If you try to read the export of full database (using wordpad !!), you will find all commands creating tablespaces, users, roles etc etc etc. Also, you will see commands which alter the users SYS and SYSTEM to change the password !!!
Any past experiences ??
Thanks in advance.

Hi,
>>Will the full database import change my SYSTEM's password to the system's password on the source database ?
Yes, take a look at demonstration below:

Verify the database fails in the SYS and SYSTEM schemas

Hi all,
When we execute a verify: brconnect -u / -c -f stats -v cascade -t all -p 8
we obtain some errors from some tables (NOT PARTITIONED) of SYS and SYSTEM schemas:
BR0996W Table/index SYS.UTL_RECOMP_SORTED does not exist anymore
and
BR0301E SQL error -14508 at location stats_tab_validate-2
ORA-14508: specified VALIDATE INTO table not found
BR0893E Validating structure failed for table/cluster SYSTEM.LOGMNR_TABPART$
but the tables exists.
any ideas??
Thanks in advance

HI,
try this:
sqlplus system/password
@$ORACLE_HOME/rdbms/admin/utlvalid.sql
grant all on invalid_rows to public;
exit

Backup full with DataPump without sys o system password

Hi
I am into the OS connected as oracle user which is the owner of the Oracle Software. I can connect to the database so : sqlplus / as sysdba without problems. Now I want backup full with DataPump and export utility without sys o system password.
How would be the command line ?
Thanks

None,
as Oracle advises expressly against exporting as the SYS user (when you issue / as sysdba, you are connected as SYS).
So you need to override the SYSTEM password using a documented method, via ALTER USER.
Apart from that: syntax questions are preferably not asked here as they make you look having lack of industry.

Hi;
1. How can I log in to SYS account despite being locked. Is it because i logged in through external authentication?set ORACLE_HOME, ORACLE_SID than
sqlplus "/as sysdba"
alter user xx account unlock;
2. Is locking the SYS user a standard practise ? If so, why ?
SYS and SYSTEM are default users, created with the creation of the database. Although they have much power - as they are granted the DBA role - they're still ordinary users. Because SYS owns the data dictionary, (s)he is considered a bit more special than SYSTEM. But SYS has the SYSDBA privilege which SYSTEM doesn't. This makes it possible for SYS to become a very very powerful user. This is the case when (s)he connects as sys/password as SYSDBA or / as sysdba. The as sysdba phrase is a request to aqcuire the privileges associated wht the single SYSDBA system privileges (see here).

Lock sys and system user

Dear all,
We have 10.2.0.4 on solaris 10.
Currently we had I.T audit on our environment and auditor commented to lock sys and system user and use one user with any name (not oracle generic name) and grant him sys and system privilege and to use this user for admin purposes. is this right ?.. is this recommended ?
Please advise

Hello,
I think it's not a right way to lock SYS.
More over, if you connect as OS Administrator (root for Unix/linux) on the server and use
OS Authentification then, you can connect on SYS AS SYSDBA anyway.
So, in fact, it's not possible to lock out SYS even if you execute the following:
ALTER USER SYS ACCOUNT LOCK;If you want to prevent access on SYS you should set a complex and long password and
apply the same rule for the Administrator / root OS user.
These passwords must be known by very few and well - identified people and written nowhere
(in any files or scripts).
More over, you should limit DBA roles to SYS and SYSTEM and remove this powerful Role
from other Oracle Users.
Then, you may enable session AUDIT so as to control the connexion on the database and,
create a LOGON TRIGGER so as to check the login, workstation, program of the end users
who connect to the database.
On 10g, EM DBConsole shows an alert everytime a User is connected with SYS.
Please, find enclosed, an interesting document written by Pete Finigan on this topic:

Hope this help.

Profiles apply to SYS and SYSTEM users

dear all.
is possible configure the security policies (profiles), i mean password length, history, failed login attempts for SYS and SYSTEM users in oracle 10g.
What will happen if both users blocked ?? the service would be affected ???
what would you recommend me ?
thanks for your answers and apologize my english, is not very well.

Check here:
SYS account cannot be locked out by setting the failed_login_attempts limit in the profile.
is it possible to lock out SYS using FAILED_LOGIN_ATTEMPTS in a profile

Access to sys and system accounts

How to determine who can access sys and system accounts?
we have oracle 10.2.0.4. I want to know which users can access sys and system accounts?
Please advise
Thanks

ski123 wrote:

Even inside Oracle, it is possible to logon as SCOTT and execute SQL and PL/SQL code as SYS - without having any DBA like privs or access to the password for SYS (possible by using a compromised DBMS_SYS_SQL package).
Bottom line is, you cannot just look at privs inside Oracle to determine who has SYS access. Security and hardening are more complex than that.

Sys and system schema are expired & locked after doing disaster recovery.

Hi All,
In one of our development database, I performed disaster recovery and it was successfull.
After completing thre recovery, sys and system schema are expired & locked.
So, I am not able to perform any kind of operation which is performed by sys and system user.
Database Version : 11g r2
Operating system : Red hat 5.5
Please kindly suggest me, How can i solve this problem?
Thanks,
Viren Patel.

This is some sort of a mirracle. SYS even if expired and locked - can login:
SQL> SELECT d.username, u.account_status
2 FROM DBA_USERS_WITH_DEFPWD d, DBA_USERS u
3 WHERE d.username = u.username and u.username=’SYS’
4 ORDER BY 2,1;

SYS                            OPEN

When creating application: SYS and SYSTEM users may not create applications

Dear all,
When i am performing the below mentioned operations
1) Importing Application
2) Create Application
3) Create from Spreadsheet
4) Demonstration Application
am getting this error message
"SYS and SYSTEM users may not create applications"
Please do the needfull

Create application using SYS or SYSTEM user is not good idea. Your objects will be created in SYSTEM tablespace, it's fatal option. Create new Workspace and create there your app.

Restrication on using sys and system tables.

I have created the user in oracle 10g, granted resource , connect , select, insert, and update any table
I would like to restrict the user from modifying sys and system tables.
I know , it is possible using triggers. but it will create perofrmance issues
Any other solution , please let me know

user wants this priv ( user is super user ) but user is not DBAYou say the user is not a "super user" and is not a DBA.
Then he doesn't get what he "wants", he gets the minimum privs required to do his job. And it's the job of the DBA (presumably you) to enforce that policy. The technical issues are simple. The political ones are often difficult, but as a DBA that, too, is part of your job. It's YOUR job that will be on the line if you put the company's data at risk by granting someone excessive privileges on the database..
