Auditing and Restricting User Connections

Auditing and Restricting User Connections

This tip comes from Ajwat Ul-Hasan, Database Administrator/System Analyst, The Carphonewarehouse in London, United Kingdom.

In Oracle9i, this script can restrict users logging into the database. In one table you provide information about which users are allowed to log into the database. You can modify this script to allow or block a user with respect to application, ip address, username, osuser, terminal, etc. It is a very easy and efficient way of implementing security in database.

create table valid_users (valid_ora VARCHAR2(30),valid_os varchar2(30));and another tableCREATE TABLE USER_AUDIT(SID NUMBER NULL,SERIAL# NUMBER NULL,TIMESTAMP DATE NULL,USERNAME VARCHAR2(30) NULL,OSUSERID VARCHAR2(30) NULL,MACHINENAME VARCHAR2(64) NULL,PROGRAM VARCHAR2(48) NULL)

And then create this trigger:

CREATE OR REPLACE TRIGGER test_auditAFTER LOGON ON databaseDECLAREmachinename VARCHAR2(64);osuserid VARCHAR2(30);ora_username VARCHAR2(30) DEFAULT NULL;os_username VARCHAR2(30);v_sid NUMBER;v_serial NUMBER;v_program VARCHAR2(48);v_numuser NUMBER;CURSOR c1 ISSELECT sid, serial#, osuser, machine, programFROM v$sessionWHERE audsid = userenv('sessionid');BEGINOPEN c1;FETCH c1 INTO v_sid, v_serial, osuserid, machinename,v_program;CLOSE c1;SELECT count(*)INTO v_numuserFROM valid_usersWHERE valid_ora = user;

IF v_numuser > 0 thenINSERT INTO user_auditVALUES (v_sid, v_serial, sysdate,user, osuserid, machinename,v_program);ELSEINSERT INTO user_auditVALUES (v_sid, v_serial, ! sysdate,user, osuserid, machinename,'IN ELSE');raise_application_error(-20001,'You are not allowed to connectto the database');END IF;END;/

In the valid_user table you have to insert information about valid users, otherwise no user can log in to the database. You can generate information about user connection by using information in user_audit table.

"How to drop a datafile ?"AskTom

You Asked (Jump to Tom's latest followup)

I have a tablespace with a few datafiles.I have droped lots of tables in this tablespace and i just want to keep only one datafile on this tablespace.I know the name of the only datafile witch contains datas so i no more need the others datafiles.How can i do ?

I try to regenerate the controlfiles, it works but i can see some lines with "MISSINGXXX" in the v$datafile view so i look for another way(s) to do that because it doesn't seem very "clean".

I know that it's possible to do that with Import/Export (Export, Drop Tablespace, Import) but it's a big manipulation.

Do you have a solution to drop an empty datafile easily and properly ?

and we said...

No, datafiles are not meant to be dropped once added.Here is a support note with some methods you can use.(Doing an alter database OFFLINE DROP is not a method either).

Before we start with detailed explanations of the process involved, please note that Oracle does not provide an interface for dropping datafiles in the same way that you could drop a schema object such as a table, a view, a user, etc.Once you make a datafile part of a tablespace, the datafile CANNOT be removed, although we can use some workarounds.

Article-ID: Circulation: PUBLISHED (EXTERNAL)Folder: server.Rdbms.DBA.AdminTopic: Managing Controlfiles and DatafilesTitle: How to 'DROP' a Datafile from a TablespaceDocument-Type: BULLETINHow to 'DROP' a Datafile from a Tablespace==========================================

PURPOSE-------

This note explains how a datafile can be removed from a database.

Since there can be confusion as to how a datafile can be dropped because of the ALTER DATABASE DATAFILE OFFLINE DROP command, this note explains what steps are needed to delete a datafile and in contrast, what the OFFLINE DROP command is for.

SCOPE & APPLICATION-------------------

There are two situations where people may want to 'remove' a datafile from a tablespace:

1.You've just mistakenly added a file to a tablespace, or perhaps you made the file much larger than intended and now want to remove it.

2.You are involved in a recovery scenario and the database won't startbecause a datafile is missing.

This article is meant to discuss circumstance 1 above.There are other articles that discuss recovery scenarios where a database cannot be brought online due to missing datafiles.Please see the 'Related Documents' section at the bottom of this article.

How to 'Drop' a Datafile-----------------------------

Before we start with detailed explanations of the process involved, please note that Oracle does not provide an interface for dropping datafiles in the same way that you could drop a schema object such as a table, a view, a user, etc.Once you make a datafile part of a tablespace, the datafile CANNOT be removed, although we can use some workarounds.

Before performing certain operations such as taking tablespaces/datafiles offline, and trying to drop them, ensure you have a full backup.

If the datafile you wish to remove is the only datafile in that tablespace, simply drop the entire tablespace using:

DROP TABLESPACE INCLUDING CONTENTS;

You can confirm how many datafiles make up a tablespace by running the following query:

select file_name, tablespace_name from dba_data_files where tablespace_name ='';

The DROP TABLESPACE command removes the tablespace, the datafile, and the tablespace's contents from the data dictionary.Oracle will no longer have access to ANY object that was contained in this tablespace.The physical datafile must then be removed using an operating system command (Oracle NEVER physically removes any datafiles).Depending on which platform youtry this on, you may not be able to physically delete the datafile until Oracle is completely shut down (For example, on Windows NT, you may have to shutdown Oracle AND stop the associated service before the operating system will allow you to delete the file - in some cases, file locks are still held by Oracle)

If you have more than one datafile in the tablespace, and you do NOT need the information contained in that tablespace, or if you can easily recreate the information in this tablespace, then use the same command as above:

DROP TABLESPACE INCLUDING CONTENTS;

Again, this will remove the tablespace, the datafiles, and the tablespace's contents from the data dictionary.Oracle will no longer have access to ANY object that was contained in this tablespace.You can then use CREATE TABLESPACE and re-import the appropriate objects back into the tablespace.

If you have more than one datafile in the tablespace and you wish to keep the objects that reside in the other datafile(s) which are part of this tablespace, then you must export all the objectsinside the affected tablespace.Gather information on the curre
