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?
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 altered an user account and set the account status as expired.When I tried to connect with that user, oracle prompted for changing password.
But, after I changed the password, I got an error message as ora-01017 invalid username/password logon denied password unchangedWhat is the cause and solution for it? I am using 11g database and 10g client.
I am trying to expire all user accounts belonging to a particular profile my_profile.
The first option was to utilise the utlpwdmg.sql script to update the PASSWORD_LIFE_TIME for my_profile, this worked in Oracle (11g) but caused issues with the change password feature of several applications linking to the database - this option then had to be abandoned.
The next option is to therefore to select all users in my_profile and expire the accounts, what I require is a statement to combine:
- Select USERNAME from DBA_USERS where PROFILE='my_profile'; & - Alter USER my_user PASSWORD EXPIRE;
So that all users in my_profile have their passwords expired, not just one user my_user.
I have been plagued by people logging into my database and making changes when a clone is in process.. Having said that ,I am looking to lock accounts and unlock them when I am done.
I envision my code looking something like this:
sqlplus -s / <<END SET PAGESIZE 0 SET FEEDBACK OFF SET VERIFY OFF; set heading off; spool /tmp/lockusers.sql select 'alter user ' || username || ' account lock;' from dba_users where username not in (....) and not locked?; spool off; END;
sqlplus -s / <<END @/tmp/lockusers.sql END;
When it comes time to unlock the accounts I want to be able to unlock those accounts I previously locked and not all of them. Is there a query, I can use that can tell me when the accounts were locked or some other way about going about this so I dont unlock accounts that were locked prior to my lock script running?
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".
I've installed XE and I want to know what accounts are active. If I log in to SQL*Plus as sys as SYSDBA how can I display a list of all user and admin accounts? I want to know who can log in.
We are trying to implement the following security to our database.
As of now, the access rights are same for all the windows users logging into the Oracle application with the same Oracle user Id.
But now, we want to improve our security by granting different levels of rights to the users based on their Network Id even though they use the same Oracle User Id to log into the application.
We are not looking for the users to be identified externally.
(CREATE USER "OPS$ORACLE-BASE.COMTIM_HALL" IDENTIFIED EXTERNALLY; GRANT CONNECT TO "OPS$ORACLE-BASE.COMTIM_HALL"; )
I want to audit user connection on my reporting database, and send a report to application team on monthly basis, with a list of users who are not connected for a month and remove them.
What would be best method, i know there is LOGON trigger, or database level auditing.
I know how to use database links in various forms, but I've been trying to think through how the authentication works for a connected user link in 11g. If I create the link like this,create public database link using 'orcl';then any user can use the link, provided they have an identical username/password in the two databases. With pre-11g passwords, it was understandable: the password was salted with the username, so the hash of the password would be the same in both databases, and I assumed that the logon through the link used some sort of IDENTIFIED BY VALUES mechanism. But in 11g, the salt will different in the two databases. So the hash will be different. And of course Oracle never stores the actual password. So I don't see how the authentication works.
An Oracle user account got locked, how do I check, which program or session was the cause for it? how to fetch this details along with details like timestamp, ip address, program name.
Wanted to know for Oracle 11 version running on Solaris machine.
I have a RAC environment with 3 nodes and application using Oracle Form Reports that access the database. Every day the application cause many locks on database when execute insert, update and delete. I don't understand why so much locks. Are there a way to avoid this? Always I have to eliminate session causing locks.
I will have to provide read/write access to an oracle user. What privileges should i grant to the user so as to enable the user to read from and write to the files?
Provide me the script which would track all the users security violations like ... say for example i want to find which users logged in and what he did in database prospective.
User A contains tables, views, LOB's, types, procedures, triggers, sequences, indexes, synonyms. User B wants to have read-only privilege on the objects of User A.
I can provide select on privilege on tables and views. How about providing read-only privileges to other objects?
Is there any setting on oracle that allows to disconnect users automatically and display a message to users such: "Try a new connection to the db in 30 minutes"?
I'm checking the possibility to use Active Directory to log on the our Oracle databases. But only for dba's and developers, not application users. We use Oracle 10.2.0.4 (and soon 11g) As OS on the databaseserver we use AIX5L 5.3
Is it possible to implement Active Directory on databases running on AIX ? If it is possible, what must be done to get it to work, software ... etc ?
Just installed the new 2.0.8 version. Its been a while I am interested on using PM for our company.The problem I have is creating an Oracle DB connection. When I create a new Oracle DB connection, and test it, Steps 3 and 4 fail.What is strange is that I followed the following procedure in PM 1.9-825 and worked fine. I am wondering if something changed in the new PM 2.0.8 version (I noticed that php_oci8.dll was commented out in php.ini).
Oracle Version is 10GR2 PM installed on clean XP sp3
1. Got a new Windows XP SP3 PC 2. Installed PM 2.0.8 3. Edited php.ini and uncommented [PHP_OCI8] and extension=php_oci8.dll 4. Installed oracle instant client “instantclient-basic-win32-10.2.0.5” in c:oracle 5. Installed oracle instant client “instantclient-sqlplus-win32-10.2.0.4” in c:oracle 6. Added c:oracle in PATH environment variable 7. Created ORACLE_HOME = c:oracle environment variable 8. Added TNS_ADMIN = c: environment variable 9. Copied working tnsnames.ora file into c: 10. Rebooted. ------------------------------------- 1. Tried sqlplus connection to my oracle db and worked. 2. Launched PM 3. Created a new process 4. Created a new DB connection as follows: a. Engine:Oracle b. Server:192.168.xxx.xxx c. Database name: my_name (where my_name appears in tns_names.ora) d. Username:my_username e. Password:my_password [code]....
I was wondering if the Express Edition of Oracle Database inherited the same vulnerabilities as the whole edition? Namely I have a few hosts that have Oracle Database 11g Express Edition installed and I was wondering if they would then be vulnerable to CVE-2012-3132 and specifically the easily exploitable flaw associated with it, detailed below:
Can't use links until I've posted 5 messages, ugh..link obfu with x's and [] URL....
I have oracle 10g up and running on Solaris 10, from windows I would like to connect to sql plus through windows authentication, for that I have already made sure that remote_auth = true and have created user in oracle with OPS$. But still I cannot connect.
I have the same setup but with oracle on windows server, the os authentication from windows clients works just fine.
does oracle 10g on solaris 10 supports windows os authentication?
we know we can see lock mode held in session can be analysed using LM column in v$lock.But i confused in seeing LM column it all shows in numbers from 0 to 6.
We are using the following statement to obtain a row lock in a table in the database(ORACLE 10G), SELECT * FROM {TABLE_NAME} WHERE ID = 1 for update and if we succeed grabbing the row lock we will continue to issue a update statement every 30 seconds to preserve the lock as far as possible. here is the update statement to preserve the lock,
UPDATE {TABLE_NAME} SET time = ? WHERE ID = 1.
As you see more longer we keep holding the row lock , more update statements are submitted in the pending transaction. In normal case our application can grab the exclusive row lock and works for a long time,however sometimes a connection reset exception is thrown and our application will close the connection(I assume the pending transaction will be rolled back by the database) and exit the JVM. Since other applications will keep trying to grab the same row lock to become the master role, we expect one of them can succeed but they are all failed because the database has not released the row lock as expected. how and when the row lock can get released in our use case?
