SQL & PL/SQL :: Where Does Oracle Get Value Of Users Windows Login Name
Jun 10, 2013
I'm working on a client-server application that uses ODBC to connect Windows XP or Windows 7 PCs to an Oracle 11 database. I use a dedicated account to connect to Oracle, and I get the users Windows login name using the call shown in the title. I use the Windows login name to verify that they can access my application. I've been asked by security conscious folks in our IT department how this information is obtained
My question is: where does Oracle get the value of the users Windows login name? Is it coming from a windows registry key? Environment variable? I heard that it's possible that the ODBC driver is calling a Microsoft Win32 function like GetUserName or GetUserNameEx to retrieve the user ID.

I created an empty database using the DB Configuration Assistant, then imported a dump file provided by a client. I believe what happened is that all of the user passwords (for SYSTEM, SYSDBA, etc.) which I had created in the DB Config Assistant were overwritten during the import process as I can no longer log into the DB.
I have attempted logging into sqlplus using the /as sysdba swith while logged in to the server as a user in the ORA_DBA role, but I still get the ORA-01031: insufficient privileges message.
I am running Oracle 11g R2 on Windows 2008 R2.

I have an application that I'd like to prevent activity in after a certain time of day, say 3pm. Is there any way I can force logout of all current users and then prevent re-login until 9am the next day (short of deleting all of their login credentials and then recreating them the next morning)?

I installed the Windows 7 64-bit ODBC drivers, but the install does not seem to have made the drivers available to all users, but rather only the installing user. This install is for an image that will be cloned as a virtual machine, so the drivers, client, settings, etc. will need to be available to anyone who logs in.
Is there a way to do the install so that all the settings and files put in by the installer will apply to all users? And if so, how do you do that?

I am trying to understand how to enable some audit so we can capture OEM logins as well.
Here is my setup. Lets say my DB that i am auditing is called audit_db (audit trail set to DB) sitting on host called host_db. and we have grid control agent on this box.now my grid control is as this. Lets say my OMS and repository is on host called OMS_host.
we run query aginst dba_audit_session to get info as to who tried failed login attemps and stuff.
Now to the part that is not working.
-- this is the good part When i intentionaly login to the audit_db with sqlplus client from my laptop with wrong username/password that is captured. we get the username,os_username,userhost,terminal.
here is the sample output
username is the wrong user that i tried to login as
os_username is the my local username(ad account)
userhost is my_laptop_name
terminal is laptop_name
from above we can figure who was trying to login(failed).
-- this is the bad part But lets say i try to login to audit_db through grid control and use wrong username/password.that gets captured too(but not all of it). we get the username,os_username,userhost,terminal.
here is the sample output
username is the wrong user that i tried to login as
os_username is the user of OMS repository db(oracle)
userhost is oms_host
terminal is unknown
Now with the above info, we cannot figure out who tried to login with bad login credential.

We have a .NET application on windows server 2008 32bit using the stored procedures on an Oracle 10g environment. We are trying to deploy the .NET application onto a 64bit x86 Windows server 2008.
We face an error trying to install the x64 version of the Oracle 10g client on windows 2008. The error we get is Problem signature:
Problem Event Name: APPCRASH
Application Name: javaw.exe
Is the x64 version of the Oracle 10g client certified for Windows 2008? Has anyone successfully installed the 64bit version of the oracle client on win2008?
We have a workaround in place with 32 bit version of the client running with the 32 bit version of the .NET application on x64 win2008. However to maximize the infrastructure we need to use the 64 bit version or we would have to turn to MSSQL Server .

I am trying to find out if there is a definite way to find out (by querying database) which database users have been created by Oracle (either during installation or as part of patching or adding new feature) and which database users have been created by DBAs.
I have looked into the documentation but could not find anything relevant. Ideally, I would like to know if this can be done for any versions starting from 9iR2.

During installation of a database Oracle creates several users. Also when using DBCA in a later stage to add more options Oracle can create more users.
Here's my problem: Public synonyms never get exported using exp(dp)/imp(dp) utility. Ofcourse using public synonyms isn't good practise, but sometimes handy. Unfortunately in our environment they have been used a lot in the passed.
So I want to create an SQL statement that does the trick and returns only all users that were NOT created by Oracle software.
I've tried several things, but can't seem to distinguish Oracle users from Manually created users.

I am looking for a query which can select all existing Oracle predefined users and roles from db.I need it because one of my other scripts needs to know a given user name or role is a customised one or a system one.It looks like sys.user$ does not have any column that can be used to distinguish predefined users/roles.
I could find all the list of Oracle predefined users and roles by googling and hardcoded them in a query. I can also collect all the customised users and roles as well. However, I prefer a query which can automatically reports that and minimise the maintenance cost as new names and roles, either Oracle predefined or customised, may come out at anytime.
