Audit of Dropped table
Hi
i have Oracle 10g R2 i'm facing one problem, that there is a table which has been dropped it's in Recycle Bin there is many information about dropped table like Dropped time, user and etc..
But i want to know the Terminal or Machine name which the drop command was issued.
Please guide me in this regard.

Hi Masir,
For DDL auditing, consider a DDL trigger:
http://www.dba-oracle.com/t_ddl_triggers.htm
Using the Data Definition Language (DDL) triggers, the Oracle DBA can automatically track all changes to the database, including changes to tables, indexes, and constraints. The data from this trigger is especially useful for change control for the Oracle DBA.
DDL triggers execute every time a DDL statement is executed, and adds new entries to your new table, as shown below:
connect sys/manager
create or replace trigger
DDLTrigger
AFTER DDL ON DATABASE
BEGIN
insert into
perfstat.stats$ddl_log
user_name,
ddl_date,
ddl_type,
object_type,
owner,
object_name
VALUES
ora_login_user,
sysdate,
ora_sysevent,
ora_dict_obj_type,
ora_dict_obj_owner,
ora_dict_obj_name
END;

Your first question is easy, you configure audit to log to the OS audit trail with
alter system set audit_trail=os scope=spfile;
and then enable audit for whatever actions you want to capture. All documented in the Security Guide.
Your second question makes no sense unless you explain what you mean by "oracle log". -
Allowing a user to create/drop tables in another users schema
We have a central shared schema (TEAM). So we can monitor who is doing what users have there own login(USER1, USER2...). Is there a way to allow a user to create/drop objects in another user.
I.e.
SQL> connect USER1
SQL> create team.table1(col1 char(1));
SQL> drop table team.table1:
How can this be set up?
BenHere is what you can do, If you want to keep track of what users are doing.
Open the glogin.sql file and set the spool like this
spool /oracle/audit/SID_&_user.logEverytime user logs in it will be populated and you will be able to see who is doing what.
You can remove the write permission on glogin.sql so that no one can modify it.
You also need to create a script like this, which would rename it every time same user would login.
#!/bin/ksh
time=`date +"%b"_"%d"_"%H"_"%M"`
##you need to pass some more variables and while loop to include all the users## ( This is just for an example)
if [ -f /oracle/audit/SID_SYS.log ]
then
mv /oracle/audit/SYS.log /oracle/audit/SYS.log.$time
fiEdit the glogin.sql file with this script information like this
host /oracle/audit/file.kshHope this helps, if you need more information let me know. -
Hello expert,
Please tell me how to find out who have dropped a table in the oracle database.
Many Thanks,Yes, it is possible the table is in the recycle bin and can be recovered. It is also possible that there has been demand for space in the tablespace in question and that the recycle bin copy space has had to be reused. It will depend on the environment, but checking the recycle bin is an excellent starting point providing the database is 10g+.
Querying v$sql for the drop command is also time (and load) dependent.
I suggest you configure auditing in all production environments to audit DDL since tables should rarely be created, altered, or dropped in production. Knowing when objects are added, altered, and dropped can be valuable when trying to track down process changes and for some other DBA tasks.

Hello,
I'm currently tring to drop a table using a process trigered by a button click
Icreated my button and also a "PL/SQL process" and I put
DROP TABLE &P0_TABLE_NAME. CASCADE CONSTRAINTS;

But when a click on the button I have the following error
ORA-06550: line 1, column 7: PLS-00103: Encountered the symbol "DROP" when expecting one of the following: begin case declare exit for goto if loop mod null pragma raise return select update while with <an identifier> <a double-quoted delimited-identifier> <a bind variable> << close current delete fetch lock insert open rollback savepoint set sql execute commit forall merge pipe

Do anyone have a clue about this ?

You can't used directly a DDL statment.
But you can use an EXECUTE IMMEDIATE in your process.

Drop table if exists in sql statement
Oracle: 10G
Is there a way to check if table exist and then only drop table. Something like:
drop table (select table_name from user_tables where lower(table_name) = 'o2i_filing_dest')As already suggested, you could e.g. use an anonymous PL/SQL block as part of your SQL script, e.g. something like that:
set echo on
spool <your_log_file>
WHENEVER SQLERROR EXIT FAILURE
DECLARE
PROCEDURE EXEC_DONT_FAIL( P_CMD IN VARCHAR2 ) IS
e_table_or_view_does_not_exist exception;
pragma exception_init(e_table_or_view_does_not_exist, -942);
e_type_does_not_exist exception;
pragma exception_init(e_type_does_not_exist, -4043);
e_sequence_does_not_exist exception;
pragma exception_init(e_sequence_does_not_exist, -2289);
BEGIN
EXECUTE IMMEDIATE P_CMD;
EXCEPTION
WHEN e_table_or_view_does_not_exist OR e_type_does_not_exist OR e_sequence_does_not_exist THEN
NULL;
END;
BEGIN
EXEC_DONT_FAIL('drop type <type_name1> force');
EXEC_DONT_FAIL('drop view <view_name1>');
EXEC_DONT_FAIL('drop table <table_name1> purge');
EXEC_DONT_FAIL('drop sequence <seq_name1>');
END;
CREATE TABLE ...Note that the literals in angle brackets are just placeholders for demonstration purposes, you need to use your actual object names/file names there.
Of course you could also use a FOR ... LOOP in the PL/SQL block that queries e.g. USER_OBJECTS to find out which objects to drop.
That way it is ensured that only expected exceptions will be ignored but all others will raise and stop your script in that case.

Dear All,
I created one table like

after performing some operations I want to delete the same.
At that time i got following error. Please help me and tell what is the reason for the error.
ORA-00604 error occured at recursive level1

ORA-20123 is a localized/customized error code & message; therefore any solution depends upon what is unique inside your DB now.
I suspect that some sort of TRIGGER exists, which throws posted error, but this is just idle speculation on my part.

I created a table with tablename USER using an access to oracle converter. now I am unable to drop the table, it says invalid table name.
These are keyword and NOT at all recommended as table name. You can find those types of words by querying
SELECT * FROM v$reserved_words ORDER BY 1 and avoid use of these words as object name.
However. Now you can enclose the name with a double quote to overcome the situation.

As the HR user I created two tables and created a FK constraint between them. After truncating the table with this FK, I am unable to drop it. Even if I remove the FK, the error is the same. Issing the command in SQL*Plus gives the same error.
This is the first time I have created any tables since installing Oracle on this machine and is my first attempt at dropping a table. I have not created any sequences, triggers or views based on these newly created tables.
Does anyone have any ideas?

Dropping tables in Oracle 10g Express
I have several schemas created in my oracle express db. And I have created 1 user, 'met' that has privs to do anything in any schema.
If user met drops a table in the acct schema, it does not go in the acct recyclebin like I would think. It is renamed BIN$...... and left in the acct schema.
If acct drops a table in the acct schema, then it shows up in the acct recyclebin as the same name it had in the schema.
We have 40+ schemas, and I don't want to login as each individual user to manage there tables, I want one account to manage them all, but do not want to leave alot of BIN$..... tables in the schema when I drop a table.
I know I can purge them, and remove them for good, but If I want to drop a table, and have a backup for a while, I want it to be in the recyclebin.
Anyway to fix this, or is this just how it work?You may want to use the purge command:
PURGE recyclebin;
Or disable the recycle bin parameter, which will diables the flashback feature and won't allow you to recover any mistakenly dropped table:
RECYCLE_BIN=FALSE;
