When a user is renamed in Active Directory, they can no longer connect to the Oracle DB thru OS authentication. There is no OID/DIP integration.
sqlnet.ora SQLNET.AUTHENTICATION_SERVICES = (NTS) NAMES.DIRECTORY_PATH= (TNSNAMES, HOSTNAME) NAMES.DEFAULT_DOMAIN = cal.com.br create user "CALRENATOH" IDENTIFIED EXTERNALLY GRANT CREATE SESSION TO "CALRENATOH" AD User CALRENATOH can connect to DB as 'sqlplus /'
But after renaming AD User CALRENATOH to CALRENATOH1 and dropping DB user CALRENATOH and creating DB user CALRENATOH1 drop user "CALRENATOH"; create user "CALRENATOH1" IDENTIFIED EXTERNALLY;
Now OS authentication 'sqlplus /' fails 'ORA-01017: invalid username/password; logon denied'..Once I recreate the DB user with old AD user name 'CALRENATOH', OS authentication succeeds. create user "CALRENATOH" IDENTIFIED EXTERNALLY;

Why the Database is still looking for old AD user name? Does Oracle cache information about OS authenticated users?
I have enabled Auditing in my oracle Database but I am not able to see any database for the operations of sys user or any other user in my "SYS.AUD$" and "SYS.FGA_LOG$" tables.
Value for the parameter "AUDIT_TRAIL" is set to "db,extended".
I am working as "SYS" user and I have shutdown and again startup the database but neither there was any information in both the tables nor I can see any files at the destination specified by "AUDIT_FILE_DEST".
We have an application with many separate databases (one per customer). Given they share the same business requirements (service hours, change mgmt etc), we're interested in potentially consolidating the separate DBs (which are relatively small) into separate schemas within a fewer no of databases to reduce the overhead.
Our issue is that the application is hard-coded to use a specific administrator and application connection user name. Changing this is unfortunately not an option.
Given this limitation, is there any possibility to map a generic user into a customer-specific schema based on the database service that they connect to? Each customer connects to different database services but may use the same user name. We considered using private synonyms but this seems to acheive the opposite (i.e. many different users could connect and map to a single users schema). One thing to point out is that where there is a single user name, it is acceptable for a single password to be used across the different customer DBs as they will be a single admin/user.
Last week we have realized that a user who connects through SQL Developer(as nothing wrong found in application server logs) has made a serious change in the database which created a real mess. The user has done some mischief in some calculations by making some inserts and updates in some important tables in our production database.
How can I find which user or from which IP the change is made.
I have a doubt in locking user account in oracle database.I was told to drop some unusable users in database which my clients dont require them.I verified the dependent objects of those users but not sure if these users can be dropped.
Instead can i make those user accounts locked so that they cannot connect to database? Would there be any impact on database performance if i lock those user accounts?
Is locking an account and dropping users is similar in anyway?
We have almost 400 production two-node RAC clusters in the environment I manage - all these sites have databases where the database name is exactly the same, so using Grid Control right now isn't in the cards (and yes - I am working on assigning them all a unique name ). We want to use IBM's BIGFIX to deploy patch 32 on top of 10.2.0.3 for Windows Itanium. BigFix runs as a user different from that used to install the Oracle software originally. There is nothing in the patch notes to suggest that you must use a certain Windows user to install the patch - so the question is, does it matter what Windows User I use as long as they are an 'Administrator' equivalent?
how do you perform mass updates/patches in your Windows server environments? I am looking for examples outside of Grid Control - which I know would work if only my predecessor didn't name these databases the same .
From Windows, I can successfully create and connect with a system data source using an user Oracle account.But when doing then same configuration process I can not create or connect using the 'SYS' account.
i get the error 'ORA-2009: connection as SYS should be as SYSDBA or SYSOPER'.
What is the solution to creating an ODBC DSN for the user 'SYS'?
we are trying ti implement BMC monitoring tool for our oracle 11g2 RAC/solaris10 environment. for the purpose we create a user called bmcuser in OS level, this user connecting database to monitor, this user occupy shared memory as oracle. Explain why this user taking that much shared memory just to connect database using sqlplus.
oracle taking 55% bmcuser taking 44%,

Quote: SESSIONS_PER_USER Each instance maintains its own SESSIONS_PER_USER count. If SESSIONS_PER_USER is set to 1 for a user, the user can log on to the database more than once as long as each connection is from a different instance.
Of course the following is not working even when resource_limit is TRUE
ALTER PROFILE DEFAULT LIMIT SESSIONS_PER_USER 2;
How can I restrict a user to have limited sessions say 2 sessions across 4 node cluster? Presently I am checking the sessions logged in using sql+ and no connection pooling of front end etc. is involved.
I am using Oracle Internet Directory to store user information and OID delegation administratibe services for user entry. An an admin I created a privileges group called admins. Users belonging to this group can create user, delete users, edit users, and edit groups. I created 'User A' and assigned him to the group. Now 'User A' creates 'User B' and assignes him to the group. However when 'User B' creates 'User C' he gets the error [LDAP: error code 50 - Insufficient Access Rights].
This happens even though 'User B' belongs to the admin group which has the privilege to create users.
The application user owns the application schema which owns all the database objects in this schema. Now 50 of our developers need access to this application schema but giving away the password for the application user is risk as "Drop user application cascade" and wipe off all the objects. The option i have is to create 50 separate users with tablespace as application and grant all rights to application schema.
We like to integrate the window LDAP to a new oracle database for user authentication. For example, this is a new test database and we don't have any users created.Now we like to figure out if we created the users with same id as in LDAP userid, how they can be authenticated externally by LDAP. I read and heard some info on OID provided by oracle but need some more step by step info to experiment.
