Logon Database Trigger

I want to write a database trigger that fires when a user logs onto the database. Oracle has this in 8i+.
I am using 9i.
I want to use this trigger to determine if the session is questionable(ie. Hacker). If it is then i want to either kill the session or audit it.
Auditing is turning on for the database.
I am trying to use
execute immediate 'audit all by %username%'
where username is from the v$session for the current session.
It appears the logon trigger is fired but the session is not being audited.
My question is how can I make the session be audited from within a trigger?
Thanks for you help.

When I login in sqlplus I get the error from the after login trigger, but after I get logged in I can issue ALTER SESSION ENABLE RESUMABLE and it works fine (session altered) So why does it let me alter the session after I get logged in, but not during the after logon trigger.It's probably because you have the privilege granted to a role and not a user. Roles are disabled when it comes to definer's rights (default).

LOGON ON TRIGGER를 이용한 접속제한 | TRACE 설정

제품 : ORACLE SERVER

LOGON ON TRIGGER를 이용한 접속제한 | TRACE 설정
===============================================
PURPOSE
데이터베이스에 접속하는 IP, USERNAME으로 접속을 제한하거나, TRACE를 설정하는 방법에
대하여 알아본다.
Explanation
DB를 접속하는 사용자를 USER/ROLE로 구분하여 관리하는 Accecs Policy 라면 관계 없지만
하나의 USER/PASSWORD로 Application을 이용하는 경우에는 Application을 통해서만
DB에 접속하도록 통제하는 것이 불가능하게 된다.
즉 일부 사용자가 PC에 설치된 SQL*Net을 통하여 SQL*Plus나 3rd party TOOL로 DB에 접속하여
데이터의 열람/조작을 한다면 이를 방지하거나 추적하기가 어렵다.
아래 예제는 DB server로의 TELNET접속을 통한 특정 DB User(SCOTT)의 접속을 원천적으로 막고,
특정 IP(152.69.41.232)로부터 접속하는 Session에 trace를 설정하는 예제이다.

Administer database trigger - ora-01031

hello,
I have problem with my trigger. I want change schema for users, witch logon on database. I put trigger in forms when I make new users and I now that this trigger is ok, but I get error ora-01031. I put privileges (administer database trigger)for user witch execute this trigger and I still get this error.
I heard that must by sys as sysdba but I don't think so.
any idea?
regards

You are right. I check this. thanks
This was good idea but, not work.
GRANT ALTER SESSION TO SCOTT;
If I log on to scott and I fire trigger I get this error ORA-01301.
another solutions? Maybe I make samphing wrong?

Multiple Rows Update / Refresh Toplink Query when database trigger involved

Hi everybody!
I have two easy troubles for you; the platform is the same as the SRDemo Toplink version.
1. Multiple Rows Update: I want to update with mergeEntity method, multiple rows for an isolated table; that method receives a parameter that I try to bind with the iterator "dataProvider" but it only merges the first row, not all, any other combination returns an error.
What I want to do is to have a form (like tabular forms in Apex) that lets me update multiple rows in a single page. ¿May anyone tell me how to do it?
2. Refresh Toplink Named Query: I have a list on a page with two columns. From another page, a button does an action that fires a database trigger that updates one of the columns on the list´s page. When I go back to the list, it is not updated; however, the CacheResults´s property is set to false on the iterator.
Thanks in advance,
Alejandro T

I didn't use it (yet), but - you might take a look. You'll find a [url http://www.oracle.com/technetwork/developer-tools/apex/application-express/apex-plug-ins-182042.html]Timer plug-in on this page. It is a dynamic action which allows you to periodically fire other dynamic actions in the browser. For example use the timer to refresh a region every five minutes. You can perform any dynamic action you want using this infrastructure.So I was thinking: you might use it to run a dynamic action which would check whether something changed in that table (I suppose you'll know the way) (for example, a database trigger might set a flag in some table, timestamp or similar), and - if you find that something really changed - refresh the page.
As I said, I never used it so that's pure theory. Someone else might know better, though.

How to get SSO logged user information in a database trigger

thanks

Hi,
The only way I could figure out how to get it was to import the com.sap.security.api.
1. From Window>Preferences>Java-->Classpath Variables, set up a variable called WEBAS_HOME pointing to:
<drive>/usr/sap/<SID>/jc00/j2ee/cluster/server0/
2. Right click on properties of your Dynpro Project->Properties->Java Build Path->Libraries and click "Add Variable."
3. Select WEBAS_HOME and click "Extend"
4. Select /bin/ext/com.sap.api.sda/com.sap.security.api.jar and click OK.
If you don't have access to a portal directory, you will have to get this jar file and copy it to your workspace to add to your build path instead of the above steps.
Then in your code:
import com.sap.security.api.IUser;
import com.sap.security.api.IUserAccount;
public void GetLogonID( )
     String LogonID;
     try {
          /*     create an user object from the current user */
          IWDClientUser wdUser = WDClientUser.getCurrentUser();
          IUser user = wdUser.getSAPUser();
          if (user != null) {
               IUserAccount acct = user.getUserAccounts()[0];
               if (acct != null) {
                    LogonID = acct.getLogonUid();
               } else
                    LogonID = "acct null";
          } else {
               LogonID = "user null";
          wdContext.currentContextElement().setDisplayName(user.getFirstName() + " " + user.getLastName());
          wdContext.currentContextElement().setLogonID(LogonID.toUpperCase());
     } catch (Exception e) {
          e.printStackTrace();
Hope this helps... I had to search several places before I found all the necessary stuff. Maybe I can get my first points!
Thanks,
Andrew

Report in PDF format and email it to some clients, using Database Trigger

Hi
Is it possible to run a report in PDF format ad email it to some clients after a specific event through Database Trigger. For example whenever a client makes an entry into order entry table (through entry form), a trigger should execute on Orders table, this trigger should execute or generate a PDF formatted report and finally mail it to Sales team?
I have
ORAS 10g(10.1.2.0.2)
utl_mail configured.

In Reportsconfig.properties file the http port is 7778,

How can I create a pdf-report in a database trigger

Hi,
how can I create a pdf-file with Reports 9i in a database trigger ?
Where can I find informations about it?
Thanks

Here would be the place to start.
If you have existing reports to call, take a look at the JRC

How can I obtain an specific message raised by a database trigger

Dear friends,
if I have a database trigger and I want to show an error message which was raised from a database trigger to a form, I can do it by raising an application error inside database trigger, and by showing DBMS_ERROR_TEXT inside ON-ERROR trigger. This is ok for me.
But how can I do if I want to show a specific message? Let's say I have a BEFORE INSERT table trigger, and I want to verify whether data was correctly informed (for example, "user name must be entered"). If I raise an application error, I see a very big error message which includes both my personal error message and database message.
Surely I can do a SUBSTR in this message, but can't I do something easier? Let's say I put all error messages in a variable:
(Let's suppose it's a BEFORE INSERT trigger code, which is related to my table)
if :NEW.user_name is null then
p_error_message := 'User name must be entered.';
end if;
if p_error_message is not null then
raise_application_error (-20000, p_error_message);
end if;
... with this p_error_message being shown to final user, with no need to edit it via PL/SQL instructions like SUBSTR. Is this possible? If not, I'll be quite satisfied with SUBSTR because it fits my needs somehow.
Best regards,

raise_application_error will be used for raise errors on form.here i'm providing u the example
CREATE TRIGGER at AFTER UPDATE OR DELETE OR INSERT ON emp
for each row
declare
v_1 number
begin
select empno into v_1 from emp where empno=7369 ;
exception when no_data_found then
RAISE_APPLICATION_ERROR(-20001,'No data found'||sqlerrm);
END;
now when you insert data on emp table through form. if value does not found of selected empno then No data found will be shown on form

How to specify when clause in a database trigger

I would like to create a database trigger that only fires on database create statements. In particular, it only needs to fire when tables with a specific prefix fire.
I'd like to be able to specify something in the when clause along the lines of :
CREATE OR REPLACE
TRIGGER CAPTURE_STATS
     after CREATE ON rtrei.schema
     WHEN ( NEW.table_name like 'RT_FOO%' )
begin
add_stats_capture( :new.min_range, :new.max_range);
end;
It looks like I should be able to use a when as part of a database trigger, but I have no idea what new would be defined to be so that I could use it... perhaps it is an object and the clause would look something like
when (new.objecttype = 'TABLE' and new.name like 'RT_FOO%')?
Any ideas? I've searched through the docs, but have not been able to find anything relevant.
thanks very much,
Robin

You can use the WHEN clause with DDL triggers. You can move Todd's IF-THEN clause up into the WHEN clause.
See http://download-west.oracle.com/docs/cd/B14117_01/appdev.101/b10795/adfns_ev.htm for all of the System-Defined Event Attributes.
CREATE OR REPLACE TRIGGER capture_stats
AFTER CREATE ON SCHEMA
WHEN (ora_dict_obj_type = 'TABLE' AND ora_dict_obj_name LIKE 'RT_FOO%')
BEGIN
        --Do whatever here.
END capture_stats;

Is there an AUDIT option like AFTER SERVERERROR database trigger?

I want to log any and every error-exception in a test database for a period.
I have seen DBMS_UTILITY.FORMAT_ERROR_BACKTRACE article published on Oracle Magazine;
http://www.oracle.com/technology/oramag/oracle/05-mar/o25plsql.html
But before trying to build a custom application like this one;
http://apex.oracle.com/pls/otn/f?p=2853:4:1160653345033883::NO::P4_QA_ID:5922
1- I wanted to be sure if there is a specific WHENEVER NOT SUCCESSFUL Audit option for this need?
2- Also is there a way to capture NO_DATA_FOUND exception with AFTER SERVERERROR database trigger?
Thank you,
Best regards.

some stuff like following;
1)
-- the right one is conn hr/hr
conn hr/eychar
2)
-- the right one is grant select on employees to public;
grant select onnnn employees to public;
3)
create or replace procedure p1 as
begin
raise_Application_error(-20001, 'catch me if you can');
end;
exec p1;
again thank you for your interest Michaels.

Primary Key - Generated by database TRIGGER

Hi,
I have a form with a block that is attached to a table. So far, nothing fancy :-)
The Primary is generated with an ORACLE SEQUENCE. That is done at the TABLE level with a DATABASE trigger.
So in the form, the primary field is not populated.
Works fine. But if the user wants to UPDATE the forms content, right after they did an INITIAL commit, THEY CAN'T !!!!!!!!!!!
How can I code this in the form?
Is there a way to syncronize (populate) the primary key in the form with it's table content?
If so, how do I query the table if I don't have the primary key value ?
Thanks for ANY advise,
Marc.

Another solution is to use both a database trigger and a PRE-INSERT trigger in Forms.
The database trigger should be something like
CREATE TRIGGER INS_TABLENAME BEFORE INSERT ON TABLENAME
FOR EACH ROW WHEN (new.ID IS NULL)
BEGIN
SELECT TABLENAME_SEQ.nextval INTO :new.ID FROM DUAL;
END;
and the PRE-INSERT trigger should be something like:
SELECT TABLENAME_SEQ.nextval INTO :blockname.ID FROM DUAL;
This way one solves the problem of DML RETURNING VALUE not working in Forms with Oracle version > 8 (does it work on version 8 as it is said to be? - i have not tested it anyway) and the use of other applications (SQL*Plus, JAVA, etc) without writing any code.

How to create a database trigger for automatic run statspack.snap

Hi,
I want to create a database trigger to run statspack.snap at startup.
connect /as sysdba
grant create any trigger to perfstat;
connect perfstat/perfstat
create or replace trigger auto_snap
after startup on database
begin
statspack.snap;
end;
after startup on database
error at line 2:
ora-01031: insufficient privileges
connect /as sysdba
create or replace trigger perfstat.auto_snap
after startup on database
begin
statspack.snap;
end;
Trigger created.
after shutdown and startup the database, the trigger has not been run. (no statspack snapshot)
What I have done wrong?

hi... I have created a database link but it is showing some error. Can you please tell me, do we have to update the details in TNSNAMES.ora file regarding the database which i am creating now before creating database link?????
awaiting for your response,
Thanks in advanceI'm sorry, but "showing some error" is NOT an actionable error message. Why do you think we can solve your error if you don't tell us what the error is?
Yes you will need to adjust your tnsnames. When a process in a database_A accesses database_B via a dblink in database_A, the database_A is acting as a client to database_B. At that point database_A is just like sqlplus or sqldeveloper, and all tns considerations are the same.

Column name as a variable in a database trigger

I am trying to code a pre-insert database trigger to format all varchar2 columns entered into the triggering table. I am using a cursor to get all the relevant column names from all_tab_columns, but do not know how to refer to these values in combination with the ":new" construct within my code. The example below is a very simplified version of what I am trying to do ( it obviously will not work as it is):
declare
cursor column_cur is
select column_name cn
from all_tab_columns
where table_name = 'TEMP_ASSESSMENT'
and data_type = 'VARCHAR2';
v_columnname varchar2(30);
begin
for column_rec in column_cur loop
v_columnname := column_rec.cn;
:new.v_columnname := upper(:new.v_columnname); declare
cursor column_cur is
select column_name cn
from all_tab_columns
where table_name = 'TABLE_X'
and data_type = 'VARCHAR2';
v_columnname varchar2(30);
begin
for column_rec in column_cur loop
v_columnname := column_rec.cn;
:new.v_columnname := upper(:new.v_columnname);
end loop;
end;
