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..

Encrypt sys and system tables

How to encrypt/restrict sys and system tables so that no user can view them.
On one of the database few user are having dba access.
Is it possible to restrict their access on the dictionary tables.

I have not heard of anyone encrypting the sys and system schemas, and suspect it is not possible due to the number of tools that need access to these tables and views (OEM, RMAN etc)
Maybe the application needs to run "create user" or "select * from v$session", but this does not mean that it needs DBA role. Turn on tracing or auditing to find out what priveleges the application actually needs, then grant minimum priveleges and revoke DBA.
In the worst case if the application won't start unless it has been granted a role called "DBA" then you may be able to revoke all priveleges from the DBA role and then grant them via a custom role called "MY_DBA", but there is potential for this to go very wrong, so test in a DEV environment first, and I doubt Oracle Support would approve.
Or you could use Database Vault ....

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.

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

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,

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

Dear all,
When i am performing the below mentioned operations

2) Create Application
3) Create from Spreadsheet
4) Demonstration Application

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.

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

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

To analyze or not to analyze (sys and system)! That is the question.

Hello,
There are a lot of opposing opinions out there about whether it is beneficial or not to analyze the sys and system objects? Do you guys have any theoretical or practical knowledge that backs one or the other?
Also did any one experience considerable positive impact of calculating the "system stats" with dbms_stats.gather_system_stats?
Thank you,

Some good articles to read.

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:
How to determine who can access sys and system accounts?That depends... access to SYS can be done via o/s - no need to compromise the db instance. Only the o/s account running it.
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.

Difference between SYS and SYSTEM user

Hi,
Well, one of my colleagues have asked me the difference between SYS and SYSTEM user .. Normally these are the users which will be under the monitoring of the DBA .. So, how could I know the difference between these two users ..
Please assist me
Regards

SYS is the owner of the database and the owner of the data dictionary.
The objects belonging to SYS cannot be exported. But SYS has the SYSDBA privilege which SYSTEM doesn't.
SYSTEM is a privileged administration user, and typically owns Oracle provided tables other than the dictionary.
SYSDBA is not a role, it is a privilege. You'll find it in system_privilege_map, not in dba_roles.

GSS on 'SYS' and 'SYSTEM' schemas

Hi Team,
We have both 11i(11.5.10.2) and R12(12.1.3) EBS applications. Can we run Gather schema stats on the 'SYS' and 'SYSTEM' schema and how frequent we can run on these schema ?
Thanks,

Hi,
Yes it is mandatory to collect statistics for Sys and System schema for 10g + databases.
You cannot use FND_STATS package to gather statistcs but must use the dbms_stats package. Running this once in a month or twice a month, and you can schedule this via dbms_scheduler.
All your queries are answered in note:

Any problem using bseg and bkpf tables

For fico details i using bseg and bkpf tables.
I noted that programming is very difficult because of these tables are cluster table.
plz give me other tables
if i using these tables any problem will come?

It contains transperant tables like BSIS, BSIK etc. For example to take vendor details usr the BSIK.If you use BSEG and BKPF it will take long time search. suppose your concern having lot of data means may be your server will get shutdown. So use only trasnperant tables like BSIS, BSIK etc.

Incorrect. BKPF is a transparent table and not a cluster table and you can use it just like any other transparent table. BSEG is a cluster table but there is no problem selecting from it so long as you use the key of BUKRS, BELNR, GJAHR - unless you are selecting a very large amount of data, but then this can cause problems when selecting from any type of table.
The advantage of using BSEG over the other FI line item tables such as BSIS and BSIK is that it holds all the lines of an FI document while the others will hold only a subset eg BSIK will only hold lines that contain a vendor reference and BSAS holds only cleared GL account lines. Though you can only use it when you have the key. If you need to search on vendor, you can use BSIK as a starting point, but since I usually need to get hold of all the lines on an FI document, I then have to select from BSEG anyway.

Do I need worry about the expiration of these user's password? For a normal user, I connot login with expired password
