Urgent! User SYS by given login no matter what password

Hello

Our oracle server SYS (as sysdba) user logon by given no matter what password.

Shock us and must be stopped this issue immediately as the same danger.
I modified the "SYS" user with the new password. Eventhough, always his login using any password.

Kindly guide / help me solve this problem as soon as POSSIBLE.

Thank you
Orahar.

What is your version of the OS?
What is your version of Oracle?

In sqlnet.ora SQLNET. AUTHENTICATION_SERVICES = (NTS)
Change to:
SQLNET. AUTHENTICATION_SERVICES = (NONE)

My understanding of SYS Login is like this:

If SQLNET. AUTHENTICATION_SERVICES = (NTS) and current OS user is in the ORA_DBA group in the operating system and THEN
Anyuser will be connected to any password even with 'as sysdba.
connect as sysdba anyuser/anyuser
Connect sys/anypw as sysdba
ENDIF
If SQLNET. AUTHENTICATION_SERVICES = (NONE) THEN
If remote_login_passwordfile = EXCLUSIVE THEN lock
The user SYS will be never connected even with valid password
Only sys-users will be authenticated by the file password that have sysdba priv.
ENDIF
If remote_login_passwordfile = SHARED THEN
Only the SYS user will be connected with the valid password according to the password files.
ENDIF
ENDIF

  • How can I change the password for user sys

    Hi all

    I changed sys user password using the command alter user. but the system still accept the old password; How can I remove the old password and set a new permanent password.

    also on the database machine I can connect without any password for sys and change password for all users in the database. I have this limit?

    Hello

    what you see is not a bug, your sysdba connection is authenticated by the operating system
    because your OS user is in the correct dba group, please see the MOS reference:

  • Failure to logon with the user SYS: ORA-01031: insufficient privileges

    Hello

    Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - Production

    CORE 11.2.0.1.0 Production
    AMT for Linux: Version 11.2.0.1.0 - Production
    NLSRTL Version 11.2.0.1.0 - Production

    OS: CentOS 5.5

    I can't log in with the user SYS via PL/SQL Developer. I get the message: ORA-01031: insufficient privileges. PL/SQL Developer is installed on Windows 7 Professional. Version of the Oracle Client is 11.2.0.1.0. However, I connect successfully with SYSMAN and SYSTEM.
    For those who may wonder if I try to connect 'as sysdba' when I use the SYS user, the answer is YES, I do.
    In addition, I think that the name of the tool (PL/SQL Developer) does not matter because I think I'm going to face the same error with any other tool (but I mentioned just in case).

    Server side, I have no problem with the SYS user. I can connect via SQLPlus with connect / as sysdba or connect "virtue sysdba" without fault.

    SQLNET.AUTHENTICATION_SERVICES= (NTS)
    
    NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
    I read in this forum (another thread) on the use of a password file. I created a password file using orapwd this way:
    orapwd file=orapwDB11G2 entries=100 ignorecase=y password=a_password
    where I replaced "a_password" with the SYS password.

    In fact, I'm not sure that the customer is influenced by the file password anyway because I said to use a local naming.

    Clues?

    Thank you very much!

    So your ORACLE_SID is planet but not DB11G2 , second password file must be located in $ORACLE_HOME/dbs location if you want to connect the planet of database/sid and therefore

    orapwd file= $ORACLE_HOME/dbs/orapwplanet password=syspass
    

    Then try again.

  • Question about user SYS and ROLES

    Hello

    When I create a role, such as:
    create role atestrole;
    I see that as soon as the role is created, it is automatically granted to the SYS.

    I thought that, given the fact that SYS has already all the privileges system and object in existence, that the automatic grant was superfluous and unnecessary. To test this, I have revoked the role of 'atestrole' of SYS and then tried to give "atestrole" as user SYS to SCOTT. As expected, SYS has been able to give "atestrole" SCOTT.

    At this point, it seems that the automatic granting of new roles to SYS does not SYS, being able to do something that he would be able to do otherwise.

    Question: SYS automatically grant all newly created roles, cause SYSTEM to have a few abilities that he would or not is superfluous (as seems to be)?

    Thank you for your help,

    John.

    PS: the new roles are automatically awarded to SYS by Oracle itself, it is not something to be done "manually".

    I don't know if it will clear the cloud or not! but the result is "a user who creates a role is granted also that default role.
    So, if you created the ROLE with SYS is authorized for SYS otherwise DO NOT default. See the example below.

    Thank you

    You can create the position of OEM Planner (Business Manager)

    Logged in as SYS to EM
    On the Administration tab > Scheduler option > link jobs

    Then create the job, you will find the OWNER under the NAME field, create the work by providing appropriate parameter values.

    Take a look at this below

    BEGIN
    () sys.dbms_scheduler.create_job
    job_name => ""ADMIN"". "" TEST_JOB' '.
    job_type-online "PLSQL_BLOCK."
    job_action => ' begin
    -Insert here the PL/SQL code
    end;',
    start_date-online systimestamp to the time zone '+ 6:00 ',
    job_class-online "DEFAULT_JOB_CLASS."
    observations-online "test job"
    auto_drop => FALSE,
    enabled-online TRUE);
    END;

    In your scenario that should be: job_name => ' 'your_USER. RUN_DDL_JOB"", "
    change the prefix of your code, the i.e:user_name of schema name that you want to run the task

    This problem is related with the privileges on the work of the Planner, when your job owner is SYS, and if the user HR has no privilege to run the created SYSTEM of jobs, he is unable to perform this work as HR.
    by creating employment by above way you actually create work for your user name and give him the privilege to run.

    You should look at these privileges below

    JOB SCHEDULER OBJECTS: The following privileges are necessary to perform procedures in the DBMS_SCHEDULER package.
    CREATE JOB to create jobs, schedules and programs in the scheme of the dealer
    CREATE ANY JOB create, modify or delete jobs, schedules and programs in any schema
    Note: This extremely powerful privilege allows the recipient to run code as any other user. She should be granted with caution.

    RUN ANY PROGRAM use any program in a job in the scheme of the dealer
    EXECUTE ANY CLASS specify no job in a job class in the schema of the dealer
    SCHEDULER to MANAGE create, modify or delete no matter what group of class, window or work

  • user sys and locking system

    Hi all

    We have 10.2.0.4 on solaris 10.

    Currently we have I.T. audit on our environment, and the auditor commented to lock the user sys and system and use a single user with any name (not the name generic oracle) and grant him the privilege of sys and system and use this user for admin purposes. is this true?... is it recommended?

    Please notify

    Hello

    I think that this is not a good way to lock SYS.

    In addition, if you connect as administrator (root for Unix/linux) operating system on the server and use
    Authentication of the BONE and then, you can connect to SYS AS SYSDBA anyway.

    So, in fact, it is not possible to lock SYS even if you run the following:

    ALTER USER SYS ACCOUNT LOCK;
    

    If you want to prevent access on SYS, you must set a password long and complex and
    apply the same rule for the admin / root user OS.

    These passwords must be known very little and well - to identify the people and written nowhere
    (in files or scripts).

    Plus more, you should restrict DBA role to SYS and SYSTEM and remove this powerful role
    other Oracle users.

    Then, you can enable the CHECK in order to control the connection to the session database and,.
    create a LOGIN TRIGGER to verify the connection, the workstation, the program end-users
    that connect to the database.

    In 10g, DBConsole EM shows an alert whenever a user is logged on with SYS.

    Please find attached, an interesting paper written by Pete Finigan on this topic:

    http://www.insight.co.UK/files/presentations/hacking%20and%20securing%20Oracle.PDF

    Hope this helps.

  • How to you turn off the user invited on the login screen?

    How do disable you the guest user account on the login screen?

    Basically, I have a brand new Macbook, but can't for the life of me figure out how to get rid of the guest user account.

    Summary:

    • MacBook 2016
    • El Capitan 10.11.6
    • FileVault is enabled
    • Find my Mac is disabled
    • Comments User in users and groups is set to Off

    Tried the following from another forum:

    1. make sure that 'find my Mac' and guest user are disabled, restart;

    2. check if the system integrity Protection is enabled or disabled by running: csrutil status to the Terminal.

    3 if she says ' Protection of the integrity of system status: activated. "go to 4.1.

    4. If not, only 4.4 and 4.7;

    4.1 restart in "Recovery Mode": stop and hold command + R after pressing the power button.

    4.2 go in "utilities > Terminal" and run the command: csrutil disable.

    4.3 restart;

    4.4 open the Terminal and run: sudo touch /System/Library/PrivateFrameworks/EFILogin.framework/Resources/EFIResourceBuild er.bundle/Contents/Resources, this will force the update of the connection EFI;

    4.5 reboot (again) in "Recovery Mode": stop and hold command + R after pressing the power button.

    4.6 go in "utilities > Terminal" and run the command: Activate csrutil;

    4.7 reboot and it's fixed!

    4.8 re activate 'Find my Mac' as you wish.

    -Should what settings I use to import users USER01, USER02 and data in the target database? Since I do not know the names of tablespaces

    Any help will be appreciated

    J.

    Hi J.

    The questions I have are:

    -should I start the import by datapump as user SYS?

    No, you need to import with a user in the role of "imp_full_database".

    -Should what settings I use to import users USER01, USER02 and data in the target database? Since I don't know the names of the storage spaces in the source database parameter REMAP_TABLESPACE will not help

    Well, an idea is to generate you a schema import sqlfile and see in the ddl in what tablespace, it will try to create objects.

    Impdp------' / as sysdba------' directory = dumpfile = = = USER01, USER02 patterns sqlfile

    For more information, take a look at the import documentation

  • work as user SYS have password on the computer of the Oracle

    Hi all

    my need is to work as user SYS with the Oracle server administrator password. I am beginner in Oracle administration. I have no password for SYS. But I have administrator access to the Oracle server. What should I do to restore the regular user password?

    Thanks in advance.

    Are you able to connect as a Windows user who is in the ORA_DBA group?  If so, you should be able to connect as SYS without password.  From a command line, you can

    sqlplus / as sysdba
    

    If you do this, you can restore any desired password.
