Application Express :: How To Connect As A Real Database Account User For Auditing

May 15, 2013

For auditing, I need to insert the user, among other data, into different tables. The thing is, I have an application with DB account authentication, so a real database user is connected, when auditing, the user field inserted is "ANONYMOUS".

Oracle 9i Auditing

Feb 24, 2011

I have enabled auditing in my oracle9i DB, it is running fine, generating trails and I can capture those. Recently I checked in dba_audit_session table and found os_username, userhost, terminal showing null value whereas username is captured as my own (having dba prvis). Strange thing is that it doesn't occurs everyday.

One of the possibility of running batch files may occurs such issues, but I ran this batch everyday then why it is occurring some days only.

Auditing And Implicit Commits

May 11, 2009

I'm working on a Java-based web application and we have unit tests that we use to test all our all code that interacts with the database or code that interacts with our DB code. The Spring framework allows us to perform some DML within a transaction before each test and then rollback the changes. For the most part, this works, however when I run the full suite of unit tests, it will randomly commit data to the database causing the rest of the tests to fail.

will Oracle's auditing let me see where this odd-ball commit is occurring? Is there another way for me to see when data is being committed?

This does not appear to be happening on any of the systems we've deployed, however this is a bit unsettling and would like to know why this is occurring so that we can prevent it from happening in production.

Enable / Disable Auditing From PHP

Dec 15, 2010

In PL/SQL Plus, i can enable/disable auditing when i connect as sysdba by using these command:

SQL> ALTER SYSTEM SET audit_trail=db SCOPE=SPFILE
SQL> shutdown
SQL> startup

I've done it successfully with PL/SQL Plus command line. But in PHP, how can i do that?How to execute "shutdown" and "startup" from PHP?
I've found this code for connect to oracle as sysdba:

oci_connect("/", "", null, null, OCI_SYSDBA);

From the following link:

But, i still can't execute "shutdown", "startup";

Auditing For Queries With No Where Clause

Jul 31, 2012

I'd like to audit a table for any SELECT queries that are executed against it with no WHERE clause. I've read the documentation on DBMS_FGA carefully, and as close as I can tell, creating a policy with a NULL audit_condition causes all queries against the table to be audited, which isn't what I'm looking for.

What I'd like is something like this:

DBMS_FGA.ADD_POLICY (
object_schema      =>  'scott',
object_name        =>  'emp',
policy_name        =>  'mypolicy1',
audit_condition    =>  'WHERE CLAUSE IS ABSENT',
audit_column       =>  'comm,sal',
[code].......  

SELECT * FROM EMP;but queries with conditions ('WHERE sal > 400', for instance) are not trapped.

I'm using 11gR2 (11.2.0.2) on OEL.

Auditing Unsuccessful Select Statements

Sep 3, 2013

I'm attempting to audit unsuccessful Select statements in order to trap a problem we're experiencing with our application. I have set the AUDIT_TRAIL initialization parameter to DB_EXTENDED, and bounced our database.

I've issued the AUDIT SELECT ANY TABLE WHENEVER NOT SUCCESSFUL command, and when I issue a SELECT statement as an application user, nothing appears in SYS.AUD$ even though the application has issued a select statement which returned no rows.

Security :: Auditing At Table Level In 11g?

Apr 27, 2012

We have recently upgraded our DR environment from 9i to 11g. We have auditing turned on for 3 tables.

On 9i, AUD$ table size is 11G for 12 months and the upgraded 11g environment has 9G in 2 days....

Below is the sql statement we used to turn on auditing on these tables.

audit select,update,delete on audit_Test2 by session;

Opened SR with Oracle, but no proper response from them...

what changes we need to do in order to reduce the amount of audit data on these tables in 11g?

PCI - Auditing Connect / As Sysdba - Connections?

Feb 15, 2012

I have a problem with a PCI DSS - requirement in Oracle 11.2. (PCI DSS = Payment Card Industry Data Security Standard)

Problem:

we connect via ' ssh -2 -X -l oracle hostname ' to the databaseserver and become os-user 'oracle'. we have also two offshore locations with dba's and each dba comes with his personalized user to the jumphost and then with the above ssh command to the database server.

the problem is that each dba becomes the oracle-os-account and can now connect with '/ as sysdba' to the database.in pci-dss this is not allowed !

now my question:how can I audit these '/ as sysdba'-connections and prove which user connected at which time with the '/ as sysdba' command ?

database is in audit mode. we log to syslog on linus redhat 5. I know one solution could be setting "SQLNET.AUTHENTICATION_SERVICES" parameter to "NONE" in sqlnet.ora file will make it not possible to connect to the database without a password as sysdba. (sqlplus / as sysdba). but we have to many applications and jobs and this is not really the solution in this case.

I think I can only solve this problem with personalized OS-user DBA-accounts in the dba-goup on os-site and os-user oracle should not be used for the future ?? I also need personalized dba-user-accounts in the database. using sys and system is not allowed. this users has to be locked and only for special administration work could it be unlocked.

Auditing Lob Column Changes When Working With Dbms_lob?

Oct 26, 2010

It seems that dml trigger doesn't fire when lob field is being updated using dbms_lob package.

As it stated in Oracle documentation:

QUOTE Using OCI functions or the DBMS_LOB package to update LOB values or LOB attributes of object columns does not cause Oracle to fire triggers defined on the table containing the columns or the attributes.

I need to know that table was updated (or is about to be updated), how can I do that in case it is lob field that is being updated?

Server Utilities :: Possible To Configure Auditing To Get Number Of Rows Returned By Select Statements

Aug 22, 2011

I am importing some data from Oracle into another database on a regular basis. It works fine for most of the queries but couple of queries don't work sometimes (random). I don't get any errors or any data.

We switched on the Oracle auditing to find out the queries being sent to oracle db. We can see all the queries in the Audit log. Is it possible to configure Auditing to get the "Number of Rows" returned by Select statements so that we can be sure that some data was returned.

Data Guard :: Apply Patches On Oracle Database With Logical Standby Database?

Apr 22, 2011

I got a primary database with a logical standby database running Oracle 11g. I got two client applications, one is the production site pointing to the primary one, another one is just a backup site pointing to the logical one.Things will only be written into the primary database every mid night and client applications can only query the database but not add, update nor delete.And now, I want to apply the latest patch on both of my databases. I am also the DNS administrator, I can make the name server pointing to the backup site instead of the production one.I want to firstly apply the patch on the logical one, and then the physical one.

I found some reference which explains how to apply patches by adopting "Rolling Upgrade Method". however, I want to avoid doing any "switch over" mentioned in the reference because I can make use of name server. Can I just apply patches as the following way?

1)Stop SQL apply
2)Apply patches on logical standby database
3)let the name server point to the backup site
4)Apply patches on the primary database
5)Start SQL apply
6)Let the name server point back to the production site

Streams :: Apply Archivelog / Generated Before Reset-log Of Source Database In Destination Database

Feb 9, 2013

Database Version - 10.2.0.4.0
OS - Red Hat Linux

We have configured oracle one way stream between two databases. Source database is capturing the changes (No downstream configured). Configuration was working fine but destination database was lagging behind very much i.e about 15 days behind the source database. We are ok with this but the problem is now that , as per client request we have restored previous backup and open the database with resetlog option in source database. After resetlog , archivelog sequence has been changed and stream is not working.

Can I apply the previous archivelog (before resetlog archivelogs ) in destination database anyway.Source database is a production database.
