• When clause is missing from the logon trigger

  I have a questions that looks very similar to 14840619 of Bug - FORUM - RELAXATION-CLAUSE WHEN NOT WATCH if ONLY a BASIC USER PRIVILEGES

  Assuming that SCOTT is a DBA and it issues the following command to create a logon trigger.

  CREATE OR REPLACE TRIGGER "SYSTEM". "SCOTT_LOGON_TRG" AFTER LOGON ON DATABASE.

  WHEN BEGIN (USER in ("SCOTT"))

  RUN IMMEDIATELY 'ALTER SESSION SET EVENTS "TRACE NAME CONTEXT FOREVER, LEVEL 12 10046" ';

  END;

  /

  ALTER TRIGGER 'SYSTEM '. "" SCOTT_LOGON_TRG "DISABLE;

  The trigger is created successfully.

  When you view the trigger of the developer sql code I don't see the WHEN clause.

  IM using sql developer version 4.0.1.14 (Build hand 14.48) 64-bit on Windows 7

  Is this a known bug?

  Thank you

  Bug 18603106 : WHEN CLAUSE is MISSING THE LOGON TRIGGER

• Logon trigger does not not on DB-Link?

  Hi all

  I have a serious question on the table access via a database link.

  I have three schemas:

  DATA@SOURCE

  INTERFACE@SOURCE

  WORK@TARGET

  DATA schema has a table called T1

  The scheme of the INTERFACE has select privileges on all the DATA tables. In addition, INTERFACE schema has a logon trigger change the "current schema" data:

  CREATE OR REPLACE TRIGGER TRG_A_LOGIN_SET_SCHEMA AFTER LOGON
  ON INTERFACE.SCHEMA
  BEGIN
  execute immediate 'ALTER SESSION SET CURRENT_SCHEMA = DATA';
  END;
  

  The scheme of WORK has a link database to the schema of the INTERFACE called INT_DB_LINK.

  I am now logged in the scheme of WORK on the TARGET database and I will execute following statement:

  select a from T1@INT_DB_LINK
  

  -> it works

  Then I run

  declare
    cursor c is  
    select a
      from T1@INT_DB_LINK
     where rownum<2;
  begin
    for r in c loop
      null;
    end loop;
  end; 
  

  It does not work. Error message is ORA-000942: table or view does not exist.

  But why?

  Can someone help me?

  Thanks in advance

  Hi all

  After a long, very long search I found what caused this strange behavior.

  The error ORA - was not triggered by the SQL execution engine, but by the SQL-parser/SQL-Validation.

  The second statement is that an anonymous block of SQL Oracle parser checks all the dependencies of objects before execution.

  This means that a connection is established to the TARGET to SOURCE checking if table T1 is available. The strange thing is

  that, in this respect the "ALTER SESSION" trigger is not fired. If the Analyzer does not find the object T1 in schema INTERFACE.

  If I create an empty table T1 in INTERFACE the anonymous block gets analysis/validated and the statement is executed. But this

  time the block made a normal life 'connect session' and the trigger is triggered. This means that statements access table T1

  DATA schema. (But T1 in the INTERFACE should be existing this analysis/validation works)

  I don't know if it's a bug or a feature.

  To work around this I created private synonyms in the diagram pointing to DATA objects INTERFACE.

  Thanks for your help!

• In NLS_SESSION_PARAMETERS logon trigger does not

  Hello
  
  I have a problem with a logon trigger setting session parameters:

    EXECUTE IMMEDIATE ('ALTER SESSION SET NLS_SORT=BINARY_CI');
    insert into standard.testcc (bezeichnung, datum) values ('logontrigger', SYSDATE);
  END;

  After I connect, the new row is added to the table, but the session parameters are completely intact.
  Select * from NLS_SESSION_PARAMETERS says:

  If I run the ALTER SESSION statements in the sql (standard user) console, they work perfectly, so this seems to be without end of permission.
  
  Which is wrong with the trigger?

  This explains why they are crushed, but I still don't know why the session parameters are changed after my trigger at all. Any idea?

  Problem solved: I was using Oracle SQL Developer to change my trigger and try it - and Developer SQL seems ovewrite the NLS_Session settings. Duh.
  
  Published by: 853536 on 20.04.2011 02:04

  Yes, SQL Developer usually replace the settings. It should not do this if you go to tools-> Preferences-> database-> NLS and mark 'Skip NLS Settings'.

  But any program using JDBC OCI will also replace most of the settings. Therefore, don't rely on the database to set the NLS parameters. It's applications to properly prepare the environment of the NLS (if the standard initialization based on the settings of operating system and/or NLS_LANG is not satisfactory).

• index and a nls settings logon trigger

  Hello world
  
  We had a problem with the index. A few months ago the client asked us to modify the application so that all searches are case insensitive and independent of diacritics (i.e. treat all non-ASCII as their equivalent ASCII - for example 'a' characters should be considered equal to 'a' etc.). We decided to create a simple LOGON trigger, which sets some parameters, NLS session for a given user (namely NLS_COMP = LINGUISTIC and NLS_SORT = CZECH_AI).
  
  This solution works, either it does what the customer has asked for, but I noticed there are problems with the index. Suddenly some of them are not used, so there is many unnecessary sequential scans of large tables (millions of rows), which influences the performance badly and that takes a lot more time. I believe that this is caused by the index created with the original, different from those current NLS parameters.
  
  Am I wrong? And how to fix it? I was able to recreate all the indexes, but is it possible to find what indexes are affected by this problem, or not?
  
  concerning
  Tomas

  I don't think your alter session modification statement will affect the content of the index, but they will have an impact of the plan. For example see the following example, where the full table Scan scan index range plan changes.

  Your application needs the role DBA? This is a terrible design - it violates all the principles of secure coding.

  Connection triggers trigger for users with the role of s/n, then you will not be able to use a connection here. You can leave the logon trigger and configure nodes invited and excluded in the listener sqlnet.ora file, i.e.

  tcp.validnode_checking = yes
  tcp.excluded_nodes = (hostname1,hostname2,hostname3)
  

  You need to restart the receiver after making this change.

• How to change schema in a logon trigger in 3 levels (how to define a case)

  Hello
  
  We have a web application to work... the level 1 is the database, level 2 is web server clusters... all connections use same connectionstring, same user oracle all use the same pattern...
  
  So far so good!
  
  Now comes a requirement that we must test and the 'simpler' solution is to create alternative test patterns...
  
  "of course no problem, just put a trigger of connection and the branch to a particular test instead of the regular production, a scheme"
  
  but here's my problem:
  What to put in the logon trigger?
  Since all users are the same what can I use to decide what test scheme to create a branch to?
  What sys_context information can I use to figure out (from the web server), the diagram that I can use?
  The web server authenticates the user by using active directory, and then a connection to oracle is opened
  
  I can see the logon trigger is the user active directory that was used to connect to the web server?
  
  
  Thanks for your suggestions
  
  g.

  If you really, really, really want to do this kind of thing, you probably want to look for proxy authentication, which would involve rather fundamental changes for the management of intermediate level connections.

  Even assuming you can do that kind of thing work, however, I am strongly against would do. It would make me very nervous to have test users through the same URL, hit the same web server and by pressing the same server database as users of production even though it had very well tested code which pointed users test against another scheme. You always load problems (i.e. testers are competing with production of resources users), coupling and transparency. The middle-tier and backend code are coupled (i.e. a change to a fair coincides with one change to another), but would not your test environment allows you to deploy the test code. And when (not if) there is a bug that causes some connection test inadvertently and transparently on the production scheme and some Tester causes problems in production by DML, this architecture will come under heavy fire. I would not be regarded as having any sort of ownership of the solution at this moment here.

  In addition, the authentication proxy adds complexity to a system for any advantage real, which may cause various maintenance problems on the road.

• GotoWorkspace in after Logon trigger

  Our users want to switch automatically to the last workspace they use when they connect.  Because they can use one of several applications, I decided to put this feature in a logon after tripping on the database.

  The trigger, the tables and procedures are owned by the user WM_UTILS:

  ----------------------------

  create table wm_utils.recent_user_workspaces

  (username varchar2 (30 bytes) primary key

  nom_espace_de_travail varchar2 (30 byte));

  create or replace procedure wm_utils.goto_last_workspace authid current_user as

  pragma autonomous_transaction;

  last_workspace varchar2 (30);

  Start

  last_workspace: = get_last_workspace();

  If (last_workspace is not null) then

  dbms_wm. GotoWorkspace (last_workspace);

  end if;

  commit;

  end;

  create or replace procedure wm_utils. set_last_workspace (workspace in varchar2) as

  Start

  merge into recent_user_workspaces

  using double on (username = user)

  When not matched then insert (username, nom_espace_de_travail) values (user, workspace)

  when matched, then update set nom_espace_de_travail = workspace;

  end;

  create or replace function wm_utils. get_last_workspace return varchar2 as

  workspace varchar2 (30);

  Start

  Select nom_espace_de_travail

  in the workspace

  of recent_user_workspaces

  where username = user;

  Returns the workspace;

  exception

  When NO_DATA_FOUND then

  Returns a null value.

  end;

  create or replace procedure wm_utils.goto_workspace (workspace in varchar2) authid CURRENT_USER as

  PRAGMA AUTONOMOUS_TRANSACTION;

  Start

  dbms_wm. GotoWorkspace (workspace);

  set_last_workspace (Workspace);

  commit;

  end;

  create or replace trigger wm_utils.on_login

  After logon on database

  Start

  goto_last_workspace(); 

  exception

  while others then

  null;

  end;

  ------------------------------------------------------

  Call wm_utils.goto_workspace instead of dbms_wm. GotoWorkspace if they want to remember their choice for their next login.

  The problem is that this operation fails with the error "ORA-20073: sufficient privileges to ACCESS the workspace: 'TEST_WORKSPACE'."  It is a work space owned by the user attempting to log on, but there no privileges granted explicitly.  The user can call wm_utils.goto_last_workspace () to be identified and it works.  Y at - it something on the way in which work orders that would prevent from working in a trigger AFTER logon?

  Hello

  Triggers have the same privileges as a DEFINER procedure/function.  So, once the wm_utils.on_login trigger is executed when a user connects to the database, all the procedures performed as a result of the trigger are executed with the privileges of the wm_utils schema.  This includes even those defined as authid current_user, since at this moment in time wm_util is essentially the user that executes the procedure.  So, you can create a DEFINER rights procedure in the scheme of each user to manage dbms_wm of execution. GotoWorkspace which will remove the privileges of the user running, or give the privilege of system ACCESS_ANY_WORKSPACE wm_utils schema using dbms_wm. GrantSystemPriv.

  Kind regards

• Please help - PKG and TRIGGER LOGON

  Hello
  I'm currently building a logon trigger that performs various subsidies to the objects according to the OSUSER. I tried to emulate the structure proposed here: http://asktom.oracle.com/pls/asktom/f?p=100:11:1604031168350701:P11_QUESTION_ID:646423863863
  
  The requirement is based on the OS USER logging in the basis of various privileges may be granted to certain a table.
  for example OSUSER one can only read from table T, but OSUSER B can have SUID. Our approach is to have a default role where the UID privileges are missing and should be granted to the B OSUER when the connection occurs:
  
  CREATE OR REPLACE PACKAGE LOGON_PKG AUTHID CURRENT_USER
  AS
  PROCEDURE MAIN;
  END LOGON_PKG;
  /
  
  CREATE OR REPLACE

  AS

  number of l_job;

  BEGIN
  l_str: = ' run immediately ("GRANT SELECT ON B1. ("T'S"); " ;

  -nada;
  END CASE;
  EXCEPTION
  WHILE OTHERS THEN
  -Consider recording the error and then re-raise
  LIFT;
  END;
  /
  
  Why do we try this approach? As you know, it is not possible to trigger connection directly to perform the ROLE SET-GRANT, or whether you need, and according to the post, I've referenced at all first, it should be possible using dbms_job.submit.
  
  When the syntax seems to be OK, nothing will happen when connecting. When something is missing connect is not possible and it will be returnwith the corresponding error ORA/PLS.
  
  Could you please help me?
  
  Thanks in advance.

• AFTER LOGON ON DATABASE

  Hello

  I have create a trigger to kill the unwanted remote sessions to help AFTER logon ON DATABASE.

  But the session is killed after about 30 seconds. Until the time ' select distinct username, status from v$ session; "reflecting the situation as inactive instead of 'KILLED '.

  Once the State takes the session killed get immediately terminated.

  I can understand if the status is killed and waiting for a period of time as it will only mark he shot and async... killés the session in a few seconds.

  but I'm not able to follow why it shows almost 30 second INACTIVE status.

  Thank you

  Hello

  You should not need to kill just raise an exception in the logon trigger that will kick to it-see this example on asktom

  See you soon,.

• Trigger connection problem

  We have created the below logon trigger that will check if the session is connected
  Toad,
  PL/SQL Developer
  SQL Developer.
  If it is connected via one of the above applications, the relaxation intersect if the IP exists in a table.
  
  
  This trigger works very well with

  TOAD, SQLPLUS.EXE, SQLPLUSW.EXE, PLSQLDEVELOPER.EXE

  It works simply with the SQL Developer even if the IP address is not in the table (ip_cnt = 1).
  When you try to connect from SQL Developer, the following query

  select trim(upper(sys_context('USERENV','MODULE'))) from dual

  Returns

  SQL DEVELOPER

  The trigger performs a string comparison ' DEVELOPER %. I tried the following without a bit of luck

  v_module like '%LOPER%'
  v_module = 'SQL DEVELOPER'
  v_module like '%SQL DEVELOPER%'

  The trigger Code:

  create or replace trigger admin.logon after logon on database
  declare
  
  v_module varchar2(200);
  v_ipadd varchar2(100);
  ip_cnt number;
  
  
  begin
  
  select sys_context('USERENV','IP_ADDRESS') into v_ipadd from dual ;
  select count(*) into ip_cnt from admin.ipdetails where ip = v_ipadd;
  select trim(upper(sys_context('USERENV','MODULE'))) into v_module  from dual ;
            
            
  
  
       if
            (v_module like '%TOAD%' or v_module like '%DEVELOPER%' or v_module like '%PLUS%')
            and ip_cnt = 0
            then 
            dbms_output.put_line('Value of v_module: '||v_module);
            raise_application_error (-20108, 'INSUFFICIENT PRIVILEGES TO LOGIN ');
       end if;
  
  exception
  when no_data_found then
  
  
  raise_application_error (-20109, 'INSUFFICIENT PRIVILEGES TO LOGIN ');
  
  end ;
  /

  Hello

  Try this and see if it works, maybe there is some unknown characters.

  IF v_module like '%TOAD%' or REGEXP_REPLACE(v_module,'[^[:alpha:]]')='SQLDEVELOPER'  or v_module like '%PLUS%'
  THEN ...

• Satellite P200 Vista Ultimate - Extended desktop does not remain on the left

  I can EXTEND my desktop to a second LCD on my Satellite P200 without problems - UNTIL I place it on the LEFT.

  It will not retain this position (I need to reposition after every restart - this I can live with that).

  But I use a KMV switch intensively, whenever I come back to the Satellite, the extended desktop is back on the right.

  Someone at - it ideas?

  Hello

  I think it s a display driver problem.
  Try to update the graphics driver to the latest version.
  If you will be late nothing on the European driver Toshiba page try to search on the site of Toshiba Canada and 3 websites of third parties such as www.omegadrivers.net or www.laptopvideo2go.com

  If you will not find the latest drivers try this temporary fix.
  Don t let the Windows Vista TMM to manage your multiple monitors.
  Go to Task Scheduler, in the list of active tasks, find the line task TMM, turn it off - off on logon trigger (or delete - save/export task before you do), and then restart your windows. I hope it will work ;)

• Can not find the task in the Task Scheduler

  I created a fundamental task to connect to an ad - hoc network whenever I boot my laptop with Vista Home Premium 32-bit.  I don't want that to happen and I deleted the network tries to delete the task.  When I open the Task Scheduler, I don't see my task listed.  I made sure 'show hidden tasks '.  I know that the task runs as I continue to receive errors not being to find the ad hoc network.

  I created a new task of fundamental task, called 'test' starts just the calc program and it shows in the list of tasks.

  Any help?

  As others have found, if you change the name of your computer, scheduled tasks that have been associated with a specific user account (like the logon trigger, such as the credentials for the job and so forth) will no longer appear in the list of scheduled tasks. Scheduled tasks displays the message "an error has occurred for task xxxx. Error message: the specified account name is not valid. "The same thing happens if you delete a user account that is named in a scheduled task.
   
  The reason for the problem is that the computer name part of the account name (for example, "mycomputer\myaccount"), and so if a part of the name is not valid, the associated account is no longer recognized. Unfortunately, given that the scheduled tasks will not display the task entry broken, you cannot fix it directly.
   
  The tasks themselves are defined in XML files in plain text stored in \windows\system32\tasks. The files have the same name as their entries in scheduled tasks.
   
  If a task is not desired, you can simply delete the corresponding file from \windows\system32\tasks.
   
  If you want to restore a task, you must change the computer name and/or account name everywhere wherever he is in the job file. But, you can just edit the file in place to solve the problem. Scheduled task detects that the file has been modified externally and even once will not use or display.
   
  I managed to solve the problem by following these steps:

  1. Move the file to the task entry broken of the \windows\system32\tasks in another case. You want to move it, copy it not - file must be put out \windows\system32\tasks. You can do this by using Windows Explorer or move the command in a command prompt window.
  2. Using Notepad, open the file in its new location. Set the name of the computer or the name of the account as it happens and save the file. Repeat steps 1 and 2 for all other tasks of problem.
  3. Open scheduled tasks, or select the menu Action, refresh. It should be no error message now, given that the task of the problem has been removed.
  4. On the Action menu, use the import command to locate the edited file. This will restore the scheduled task.
  5. Test the restored task by opening and then run. Once everything works, you can remove older versions of the file task as you had moved it. Repeat steps 4 and 5 for any other task edited file.
