I want to drop some users in Oracle DB using sqlplus but I am getting error:
SQL> DROP USER test CASCADE;
DROP USER test CASCADE

ERROR at line 1:
ORA-01940: cannot drop a user that is currently connected.But when I ran below command to know sessions connected I am not getting any results:
SQL> select sid,serial# from v$session where username = 'test';
no rows selected
I have a data base for the bank application development. So there might be more than one sessions of the application running on the data base as well as there might be more than one data base sessions being connected from the dbas.
There is refresh procedure to refresh the data base from the baseload scripts ,So for that first we need to disconnect the users (Kill the sessions) and then drop the users then recreate the users and populate the users with the base load data.
I have prepared the killing and dropping user script in the following manner, Most of the times it is working fine and killing the users but some times it is not able to kill the drop the users it is erroring out with the error that can not dorp the users as there are active sessions running ,
set termout on
set echo on
spool Kill_sessions_drop_users.log
DECLARE
v_alt_stmt VARCHAR2(1000) := 'ALTER SYSTEM DISCONNECT SESSION ''';
v_kill_stmt VARCHAR2(1000);
[code].......
--This will kill all the sessions except the current session
CURSOR cur_usr_dtls IS SELECT username FROM all_users WHERE username IN ('ACTIVITI','TP','TPCORR','TPTUX','TPVIEW');
v_dr_stmt VARCHAR2(1000);
BEGIN
EXECUTE IMMEDIATE 'ALTER SYSTEM ENABLE RESTRICTED SESSION';
DBMS_OUTPUT.PUT_LINE('The database has been put in the restricted mode');
FOR v_cur_ssn IN cur_session
[code]........
--Here we are making the processor to wait for 60 mins so that that the killing will happen at the OS label
DBMS_LOCK.SLEEP(60);
FOR v_cur_usr_dtls IN cur_usr_dtls LOOP
v_dr_stmt :='DROP USER '||v_cur_usr_dtls.username ||' CASCADE';
BEGIN
EXECUTE IMMEDIATE v_dr_stmt;
[code]........
we are refreshing data base for our application from the base load,Every time when ever there is refresh required we need to drop the users and recreate every thing from the base load. For this we need to kill the sessions and drop the users ,Putting the instance in the restricted mode and refreshing the db.Some time when ever During the killing and dropping process there are some errors like you can not drop the users which is currently connected .
set termout on
set echo on
spool Kill_sessions_drop_users.log
DECLARE
[code]...
how to get rid of this
I need a query to find out IP Adress for all currently connected users in V$session.

ERROR at line 1:
ORA-00604: error occurred at recursive SQL level 1
ORA-24005: must use DBMS_AQADM.DROP_QUEUE_TABLE to drop queue tables
A couple of questions on this error:
- I did a search on the forum and the thread [URL] appears to have a solution to it by using
DBMS_AQADM.DROP_QUEUE_TABLE(queue_table => 'DEF$_AQCALL', force =>TRUE);
What i am not sure of is which queue will the above statement drop if run as sys and there are multiple schemas with different schema names but with the same queue name?
- We recently rebuilt the database server and prior to the rebuild i have always managed to drop a user without the above error. Is it likely that some setting somewhere is changed?
There is a scenario: I dropped all objects of 3 users and dropped other 2 users and then I checked the space from dba_segments it reflects decreased space which is perfectly fine. Problem is that when I checked the space of physical datafile on disk it remains same. How can I restore or shrink or regained the space after dropping objects and users to maintain my storage requirements.

I'm a beginner in the PRO*C and I have this issue/I have to maintain a multithreaded C++ PRO*C application and has the following structure
1) Application runs waiting for requirements
2) When detects a requirement it creates a Thread to work
3) The thread connects to Oracle with a EXEC SQL CONNECT :uid IDENTIFIED BY :pwd; instruction
4) Calls some anonymous calls to execute a stored procedure
EXEC SQL EXECUTE
BEGIN
commit;
:Status:=stored_procedure(:param1, :param2);
commit;
END;
END-EXEC;
5) If anything went wrong then issues a EXEC SQL ROLLBACK WORK RELEASE; then reconnects and the thread die
6) If everything was OK then the thread dies, but never called a EXEC SQL COMMIT WORK RELEASE; to disconnect from Oracle
I don't know why never the application disconnects from Oracle, maybe is for performance. Sometimes the application crashes and I believe that maybe the error is for never freeing the connections, the PROC compile line is this
proc parse=full sqlcheck=full user=system/manager cpp_suffix=cpp iname=source.pc include="..Hdr" include="C:ORACLEORA81ociinclude" include="C:ORACLEORA81precomppublic"
Which is the way to implement the connections?, connect and disconnect when done? or just keep the connection alive? Which way has better performance, connect and disconnect or just keep the opened connection?

What I was trying to retrieve is something like that:

I don´t care about the order of the values in the row. In other words, I want to get disjoint sets of data connected by any of both values.Every pair in the input table is unique.
I have seen in the web that it is possible to do using connect by and hierarchical retrieving but I've been trying to make a lot of combinationts and I can reproduce the output.
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.
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.
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.

View 3 Replies View RelatedI 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.

We have 11.2.0.3 RAC on Oracle Virtual Box,OEL 5.8. Storage is ASM on EMC SAN.Even when the database is not connected to application and thus open but idle and none is working on it, and all other virtual machines are powered off, we are still getting a continuous i/o in SAN.Since I am new to RAC setup I need to know the few things...
1.Is it normal behaviour?
2.If yes, what is the reason of this i/o? Is it due to continuous ping on voting disk?..write in OCR? automatic backup of OCR?

I have few doubts in rac environment
1.In 2 node rac while adding datafile to tablespace if you forget to mention '+'then what will happen whether it is going to be create or it throws an error if it creates where exactly located and other node users how to work on that tablespace .what all steps to perform that datafile is useful for all node users.
2. In Rac environment how to check how many sessions connected to particular node.
3)In Rac any node is evicted due to network failure then after we rebuild the network .Is there any steps to do manually to access the failure node after rebuilding the network or it will automatically available in cluster group which service is perform this activity.
4.While configuring cluster ware you choose voting disk and ocr disk location and which redundancy you will choose suppose if you go for normal redundancy how many disks you can select for each file either one or two?
