Logon trigger using SRVCTL for dataguard

Hi All,
I'm running Oracle 11gR2 using the 11g grid infrastructure. I've a a primary database on one machine and a physical standby on another both registered in the CRS as their role type and hence also their startup type (eg, open, mount stage)
My issue is, when I fail over (not using broker), the CRS does not recognise that the database has swapped roles, therefore has incorrect information on what to do on startup.
The command to change this is on the physical standby side is : -
srvctl modify database -d <physStandby> -s open -r primary
and on the primary side
srvctl modify database -d <Primary> -s mount -r physical_standby
which I can do manually. I've already got a startup trigger on the database to start and stop services on the database depending on what the role is. So I thought I would try and leverage that by executing the SRVCTL command within it as well. So as a quick run, I just created a dbms_Scheduler job in procedure and ran it.
begin
DBMS_SCHEDULER.create_job (
job_name => 'TEST_JOB6',
JOB_TYPE => 'EXECUTABLE',
JOB_ACTION => '/u01/app/oracle/product/11.2.0/grid/bin/srvctl',
repeat_interval => null,
start_date => systimestamp+0.01,
number_of_arguments => 1
dbms_Scheduler.set_job_Argument_value (
job_name => 'TEST_JOB6',
argument_position => 1,
argument_value => 'modify database -d <physical_standby> -r PRIMARY'
dbms_Scheduler.enable('TEST_JOB6');
END;
And then I run it : -
SQL > exec dbms_scheduler.run_job('TEST_JOB6',FALSE);
PL/SQL procedure successfully completed.
SQL > select additional_info from dba_scheduler_job_run_details where job_name='TEST_JOB6';
ADDITIONAL_INFO
<no values here>
But when I do a srvctl config database -d <physical_standby>
Database unique name: <physical_standby>
Database name:
Oracle home: /u01/app/oracle/product/11.2.0/dbhome_1
Oracle user: oracle
Spfile:
Domain:
Start options: mount
Stop options: immediate
Database role: PHYSICAL_STANDBY # and htis value hasn't changed.
Management policy: AUTOMATIC
Disk Groups:
Services:
As you can see... nothings changed but it didn't report any errors. Has anyone done somethign similar before?

Yes, you will have to run the commands as you said manually after each role change if you do not use the Broker.
As for your job. Hmmm, I would have thought that your job should have worked. Am I correct in assuming that you ran this job after you had switched over to the standby and it is now the Primary?
We used this type of job in the MAA Client Failover paper (http://www.oracle.com/technology/deploy/availability/pdf/MAA_WP_10gR2_ClientFailoverBestPractices.pdf) where we had to manually fire the publisher for JDBC Thin clients in 10g.
CREATE OR REPLACE TRIGGER ons_JDBCpublish AFTER DB_ROLE_CHANGE ON DATABASE
BEGIN
dbms_scheduler.create_job(
job_name=>'publish_events',
job_type=>'executable',
job_action=>'/u01/oracle/product/10.2.0/db_1/bin/cfo.sh',
enabled=>TRUE
END;
It might have something to do with the argument part. Try putting the srvctl command in a script and call the wrapper script from the job and see if that works.

Sql server 2012 Logon trigger not working for certain logins

Hello. I created a login trigger to insert data for each login in a table, and it works for all logins except one that is format domain\login
and the login ends with the dollar sign(actual name is domain\CTXDEVDCSI1$).
I had been using varchar, but after reading other forum posts, I changed the varchar's to nvarchar's, but it still fails for that id.
The errors written to the sql server error log were the usual "login failed due to trigger execution".
I had granted insert on the rvvlogindata table in dsa to public, and only one id wasn't able to login after that.
Any suggestions would be much appreciated!
Here's the modified table ddl:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[rvvlogindata](
[sessionId] [int] NULL,
[LoginTime] [datetime] NULL,
[HostName] [nvarchar](50) NULL,
[ProgramName] [nvarchar](300) NULL,
[LoginName] [nvarchar](50) NULL,
[ClientHost] [nvarchar](50) NULL
) ON [PRIMARY]
GO
Here's the logon trigger code:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
create trigger [LOGIN_IP_RESTRICTION] on all server for logon
as
Begin
Declare @LogonTriggerData xml,
@EventTime datetime,

set @EventTime = @LogonTriggerData.value('(/EVENT_INSTANCE/PostTime)[1]', 'datetime')
set @LoginName = @LogonTriggerData.value('(/EVENT_INSTANCE/LoginName)[1]', 'varchar(50)')
set @ClientHost = @LogonTriggerData.value('(/EVENT_INSTANCE/ClientHost)[1]', 'varchar(50)')
set @HostName = HOST_NAME()
set @AppName = APP_NAME()
insert into dsa.dbo.rvvlogindata

Erland, I wanted to add more info to my reply earlier today.
sp_who2 showed no blocking, activity monitor from my local PC SSMS showed no major waits or high i/o or cpu activity.
I was wondering if you have any suggestions on how to find out what was the cause of the 5+ minute wait for SSMS on the remote desktop to respond and fully come up.
I definitely can't put this in production with this hanging delay possibly occurring there.
I was connecting as read_user when it hung.
sp_who2 output at the time was:

Logon trigger - restrict acces using Toad, SQLPLUS...

Oracle 10.2.0.4
I have users who use oracle form - ifweb90.exe.
I want to restrict them to access database using SQL Developer, TOAD or any other tools. I create logon trigger:
CREATE OR REPLACE TRIGGER block_users
AFTER LOGON ON DATABASE
begin
FOR REC IN (SELECT USERNAME,PROGRAM
FROM V$SESSION
WHERE AUDSID = USERENV('SESSIONID'))
LOOP
if rec.username like ('X%')
and
rec.program not like ('ifweb90.exe')
then
RAISE_APPLICATION_ERROR(-20001,'ERROR MESSAGE');
end if;
end loop;
END;
This solution don’t work if the program executable is renamed (this can’t be done with SQL Developer).
1. Is there any way to solve this?
2. Whether this trigger will use resources, whether this trigger will check all connection? What is the cost to pay in terms of performance?
Thanks in advance!

This solution don’t work if the program executable is renamed (this can’t be done with SQL Developer).
1. Is there any way to solve this?Better alternative would be to change your own program, set the client_application_info and check for that using logon trigger. Anything else, can then be thrown off.
2. Whether this trigger will use resources, whether this trigger will check all connection? What is the cost to pay in terms of performance?There would be negligible usage of resources.
But this trigger won't stop any connections from any tool which come in as SYSDBA.

How to display a logon message using login trigger?

Hello,
I have created a logon trigger similar to Tom's guide in his thread - http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:3236035522926. The guideline in the thread disables a user login, but I need the trigger to prompt a message that the logon schema has been changed to XYZ schema. Trying to use the same code format, I am able to publish the message, but at the end the connection is getting disconnected similar to Tom's example:
ops$[email protected]>
ops$[email protected]>
ops$[email protected]> connect scott/tiger
ERROR:
ORA-00604: error occurred at recursive SQL level 1
ORA-20001: You are not allowed to logon from this terminal!!!
ORA-06512: at line 7
Warning: You are no longer connected to ORACLE.
ops$[email protected]> connect /
Connected.I want the user to establish a session after login and still prompt the message. How can do that?
The trigger I am trying is -
CREATE OR REPLACE TRIGGER ABC_DBA.USER_LOGON
after logon on database
DISABLE
declare
v_user varchar2(30);
v_base_user varchar2(30);
begin
select SYS_CONTEXT ('USERENV', 'SESSION_USER') into v_user from dual;
dbms_output.enable;
dbms_output.put_line(v_user);
execute immediate 'alter session set current_schema=XYZ';
-- RAISE_APPLICATION_ERROR (-20001, 'Welcome');
end;Thanks in advance

After user is logged in without an error, the Oracle Client does not expect any message from DB.
It is up to Client Application to expect such a message.
For example if the Client Application is SQL*Plus, you can issue
SET SERVEROUTPUT ON
After that SQL*Plus will read from DBMS_OUTPUT buffer and print on the screen.
Others applications have to be programmed to do similar.

Restrict User Connections Using Logon Trigger

Hi all,
Now I am restricting user connections from selected terminals, using following logon trigger.
It allows users with DBA privileged user.
How to restrict DBA Privileged users users ?
Note:- As per my application needs DBA privilege.
CREATE OR REPLACE TRIGGER on_logon
AFTER LOGON
ON DATABASE
DECLARE
VPROGRAM VARCHAR2(30);
Vusername VARCHAR2(30);
VTERMINAL VARCHAR2(30);
CURSOR user_prog IS
SELECT UPPER(program),UPPER(username),NVL(TERMINAL,'X') FROM v$session
WHERE audsid=sys_context('USERENV','SESSIONID');
BEGIN
OPEN user_prog;
FETCH user_prog INTO Vprogram,Vusername,VTERMINAL;
IF VTERMINAL NOT IN ( 'APP1','APP2','APP3')+
and Vusername='ABUL'+
THEN
RAISE_APPLICATION_ERROR(-20001, 'You are not allowed to login');
END IF;
CLOSE user_prog;
END;
Thanks i Advance

Your application needs the DBA role? That is a terrible design-- it violates every principle of secure coding.
Login triggers don't fire for users with the DBA role, so you won't be able to use a login trigger here. You could ditch the login trigger and configure invited and excluded nodes in the listener's sqlnet.ora file, i.e.
tcp.validnode_checking = yes
tcp.excluded_nodes = (hostname1,hostname2,hostname3)You'll have to restart the listener after making that change.

Logon Screen Modificatio : Using JCo for Executing a Func Module in SAP R/3

Hi all
   I am new to Portal(EP: 6.0: SP12) and JCo.
   We are customizing the Logon Screen of the Portal to include a CLIENT field.
    And we are planning to Call a Z Function Module present in the R/3 of the specified client(in the Logon Screen) using JCO.
    But i am really new to the Environment..
    Could anyone please help in carrying out this work???
    And also i would like to know how a Fuc Module can be called with the help of JCO. Providing a sample Code would really help me a lot!!!!!!
Thanks
Kam
Message was edited by: Kam

Hi Kam
You need to create a connection to that R/3 system for that.
Try the following code:
creating connection:
=====================
IConnectorGatewayService cgService = (IConnectorGatewayService)
     PortalRuntime.getRuntimeResources().
     getService(IConnectorGatewayService.KEY);
IConnection con = cgService.getConnection("systemalias",request);
ConnectionProperties cp = new ConnectionProperties(request.getLocale(),request.getUser());
IInteraction ix = con.createInteractionEx();
IInteractionSpec ixspec = ix.getInteractionSpec();
ixspec.setPropertyValue("inputParameter","BAPI_SALESORDER");
RecordFactory rf = ix.getRecordFactory();
MappedRecord input = rf.createMappedRecord("inputParameter");
input.put("EMPLOYEE_NUMBER",empNo);
input.put("EMPLOYEE_NAME",empName);
BAPI_SALESORDER==>calling fuction
EMPLOYEE_NUMBER,EMPLOYEE_NAME===>parameter name
empNo,empName===>parameter value
<u>To retrive the value:</u>
============================
MappedRecord output = (MappedRecord)ix.execute(ixspec,input);
object rs = null;
object result = output.get("SALES_ORDERS");
if(result instanceof IRecordSet) {
     rs = (IRecordSet)result;
con.close();
Required jar files:
====================
com.sap.portal.ivs.connectorserviceapi.jar,                                  genericconnector.jar,
                   connector.jar,
                   activation.jar

Multiple logon trigger for a user

Hi,
can I create two (or more) distinct logon trigger for a user? If yes, this situation is "clean"? Both triggers are executed on logon time?

If you don't know what the wrapped source does
and you don't care about the order
then
clean := false ;-)
You filter access, but what if the unknkown wrapped source logs database access in some table on a user before your trigger DENIES access for that user/program?
You would try to find out what the already existing trigger does (third party software?), if you really want to be clean.

Newbie question for LogOn trigger and Connection String

Hi,
I would like to set certain session variables in the logon trigger. Is there a connection string attribute or some other way to pass a string or some data to the session.
regards
Stefan

Hi,
my concrete problem is that our application only uses one user. eg. appuser . During the login process of the application the "real" user name, language and other attributes are set in a packag as global variables.
This works fine, but as soon as a usr logs on the DB without our application login then these are ofcourse not filled. My idea was to maybe to be able to enhance the connection string and to be able to pass some more information to the logon trigger.
regards
Stefan

Insufficient privileges using execute immediate in after logon trigger

I have an after logon trigger that executes a package/procedure in the schema it was created in.
One of the procedures runs the following:
EXECUTE IMMEDIATE 'AUDIT INSERT TABLE, UPDATE TABLE, DELETE TABLE, EXECUTE PROCEDURE BY ' || USER;
The procedure is throwing an insufficient privileges error when executing this.
However - the schema owner has audit any and audit system privileges and - the statement works fine independently.
When I login as another user this issue arises. The package/procedure are created with definers rights... So - i'm not sure why this is happenening.
Any help is appreciated.

privileges acquired via ROLE do NOT apply within named PL/SQL procedures.

Logon trigger setting nls_date_format over ridden by sql developer?

Problem: Developers are inserting a Date record into a varchar field. I can't change this process right now. Non-Date info is stored here also. Would require a code change.
To simplify this, I wanted to get all the developers to insert using the same 'nls_date_format'. I had hoped to be able to centralize this by having Oracle set it in the database. I tried this by setting the database nls_date_format and with a logon trigger.
See test below. Seems to be over ridden.
Test case is with SQL Developer. Noticed the same thing when developers use Websphere. I think we reduce the chance for errors, if I can handle this in the database. However, my nls_date_format settings are getting over ridden.
1. s et database parameter nls_date_format to YYYY-MM-DD HH24:MI:SS , this gets over riden by SQL Developer/Websphere
2. Created a trigger with an 'alter session', but this seems to get over ridden also.
Please see test case below:
Oracle 11.2.0.3
test logging: SQLPLUS locally on the unix server, then log in using SQL Developer which is installed on my laptop.
SQL Developer NLS_DATE_FORMAT : YYYY-MON-DD HH24:MI:SS , This is different for test purposes
I have auditing turned turned on to db,extended with 'audit all by 'user' by access;' for test purposes to get more info.
create table test (username varchar2(30),sid number,mytest varchar2(300),insert_date date);
create or replace
TRIGGER LOGINTRG
AFTER LOGON ON DATABASE
BEGIN
insert into test select user, sys_context('USERENV','SID') ,value,sysdate from v$parameter where name = 'nls_date_format';
EXECUTE IMMEDIATE 'ALTER SESSION SET NLS_DATE_FORMAT=''YYYY-MM-DD HH24:MI:SS''';
insert into test select user, sys_context('USERENV','SID') ,value,sysdate from v$parameter where name = 'nls_date_format';
commit;
END LOGINTRG;
/Results/Questions
1. When I select from 'test', I confirm that my NLS_DATE_FORMAT is the same both before and after the alter session.
2. select value from v$parameter where name = 'nls_date_format'
output: YYYY-MON-DD HH24:MI:SS (so sql developer is over riding this);
3. select * from dba_audit_trail where username = 'MYUSER' order by timestamp desc;
The SQLs from the logon trigger are not captured. how do I capture logon trigger sqls? Not a huge deal, just curious
4. I do not see any alter sessions issued by my user. shouldn't audit all by access capture that? how could my session nls_date_format change without an alter session?

No - they aren't. That is physically impossible. The only thing that can be stored in a 'varchar field' is a string. Oracle considers ANYTHING stored in a character column to be a string.
Date values are stored in DATE columns. Perhaps you meant that developers are converting DATE values to strings and then storing the string in a 'varchar field'?

WONDERFUL! Why use a column to stored just one type of data? That is extremely wasteful. Hopefully you store strings that represent numbers in that same column also? It makes the data model so much easier to understand if developers only need to learn one datatype.

The horror!
You should never, ever, EVER use a code change to fix a problem if there is even the slightest possibility that you can change the ENTIRE DATABASE instead.
I've got good news though. You are now on version Oracle 11.2.0.3 and Oracle, after months of protests by some of their largest clients, has finally dropped the exhorbitant license fees for using some of the more esoteric datatypes like DATE and NUMBER.
You should suggest to your manager that they use some of the license fee money saved to hire developers that already know how to design proper data models and use those new-fangled datatypes.
Trust me - once you've made it up that steep learning curve your code will have fewer of those pesky 'dirty data' issues to deal with.
Sure - it means less job security for your current developers. But sometimes you just have to 'take one for the team'!

AUTHENICATE SSO RAD INFO IN LOGON TRIGGER IN 10G FORM?

I've been trying to add a LOGON Trigger to my Oracle 10g Form to check my RADs after logging into SSO.
I'm having a problem setting up multiple Config's for multiple RADs. I have about 7different applications that I would like to log into but would like to log into the SSO just once. But for some reason each application is asking for a SSO log in.

Hi!
This is a webutil-restriction.
You cannot use webutil in triggers that fires before the form has complete focus.
Like pre-form, when-new-form-instance and on-logon triggers.
In a when-new-form-instance trigger create a timer, let's say 200 millisconds long.
In a when-timer-expired trigger you can call webutil.
May you put your configuration-file on the server and use d2kwut !
Regards.

Exporting LOGON trigger with per schema filtering

I am using the datapump on 10.2g (on linux) to export three schemas. I am using the "SCHEMA" option in the dbms_datapump.open() procedure and then using the metadata_filter with the SCHEMA_EXPR option to limit down to my three schema. I also do some data filtering after that. Works great, except...
I found that we have one LOGON trigger which is NOT getting exported. The trigger IS owned by one of the schemas i am exporting. But, I think that because this is a "system event trigger", rather than a table based trigger, it will not export using the SCHEMA export mode. True ?
I tried switching to the FULL export mode, but then I can not find a way to limit the export to the three schemas.
All the exporting/importing is being done as system, so I don't think this is a priveledge issue.
Ideas? How to datapump specific schemas and also get the system event triggers owned by those schemas ?
Thanks very much for your help.
Bill Clery

Sure. Here is the trigger that is NOT exporting as part of the Schema export. We have a Schema called ReportView. In that schema are many views, one table, one package, and one trigger (below). Everything except the trigger is getting exported and then imported.
CREATE OR REPLACE TRIGGER reportview.startsess AFTER LOGON ON reportview.SCHEMA
BEGIN
reportview.reportapi.AutoLoadPIT();
END startsess;
The initiation of the export was done like this
PumpHandle := dbms_datapump.open('EXPORT','SCHEMA',NULL, JobName,'LATEST');
dbms_datapump.set_parallel(PumpHandle, 1);
dbms_datapump.metadata_filter(PumpHandle, 'SCHEMA_EXPR', 'IN (''ERIKSYSCORE'',''RBSAPPCORE'',''REPORTVIEW'')');
dbms_datapump.add_file(...)
dbms_datapump.data_filter(...)
dbms_datapump.data_filter(...)
dbms_datapump.start_job(PumpHandle);
dbms_datapump.detach(PumpHandle);
I tried swtiching to the "FULL" method and using the NAME_EXPR to filter down to the same schemas, but could not get this working.
PumpHandle := dbms_datapump.open('EXPORT','FULL',NULL, JobName,'LATEST');
dbms_datapump.set_parallel(PumpHandle, 1);
dbms_datapump.metadata_filter(PumpHandle, 'NAME_EXPR', ???? );

Autotrace with logon trigger?

Hi,
I've a view and the view is be reading by an external program.
How can i see how and how long do they communicate ?
Thanks in advance.
With best regards
Nicole

Hi:
If you have a testing environment (that is definitely a must have) and can modify sources the simplest way to activate trace is add a 'alter session set sql_trace=true' at the beginning of the application, then run it, and then evaluate results.
Using a logon trigger for the user the application is connecting to is another way to accomplish the same, useful when the application cannot be modified. This is an example of the same:
CREATE TRIGGER
schema_owner.logon_tg AFTER LOGON ON schema_owner.SCHEMA
BEGIN
EXECUTE IMMEDIATE 'alter session set sql_trace=true';
END;
This will produce a trace file containing all of the statements executed by the session:
Trace files go to USER_DUMP_DEST, and need to be parsed with TKPROF in order to produce readable output.
Also, check to have timed_statistics=true, so it will report timing in the trace files.
Try to produce trace files, and post if you need assistance in interpreting results.
ciao

Closing DBA session in AFTER LOGON trigger

Hello *,
this is my first question here and my first piece of code in oracle so please don't laugh ;-)
I'm trying to create an AFTER LOGON trigger which disconnects a user if he/she tries to log in from an incorrect host.
What should happen?
User tries to connect.
If he/she is permitted, a record is added to a table.
If not, a record is added to another table and the user is disconnected using RAISE_APPLICATION_ERROR().
After a number of issues I've got it working, except ... I have the feeling that RAISE_APPLICATION_ERROR() doesn't effect users with DBA privileges.
Finally, I'm testing it with one ordinary user - DEF.
The main idea is to disallow connections from user ABC which has DBA privileges.
Tests using DEF are successful but when ABC tries to log in from an incorrect host, a record is added in pcbaudit_failed_logins but the user is not disconnected.
The database is 9.2.0.8.0 and I'm prepared to post RDA report if it is required.
Thank you for your help in advance - I hope I was kind enough :P
Here's the code for the trigger:
DROP TABLE pcbaudit_users;
CREATE TABLE pcbaudit_users (username VARCHAR2(32) NOT NULL, host VARCHAR2(64) NOT NULL);
CREATE INDEX idx_pcbaudit_users_username ON pcbaudit_users(username);
CREATE INDEX idx_pcbaudit_users_host ON pcbaudit_users(host);
DROP TABLE pcbaudit_logins;
CREATE TABLE pcbaudit_logins (username VARCHAR2(32), ip_address VARCHAR2(15), host VARCHAR2(64), ts DATE);
DROP TABLE pcbaudit_failed_logins;
CREATE TABLE pcbaudit_failed_logins (username VARCHAR2(32), ip_address VARCHAR2(15), host VARCHAR2(64), ts DATE);
CREATE OR REPLACE PUBLIC SYNONYM pcbaudit_users FOR sys.pcbaudit_users;
CREATE OR REPLACE PUBLIC SYNONYM pcbaudit_logins FOR sys.pcbaudit_logins;
CREATE OR REPLACE PUBLIC SYNONYM pcbaudit_failed_logins FOR sys.pcbaudit_failed_logins;
GRANT SELECT ON sys.pcbaudit_users TO public;
GRANT INSERT ON sys.pcbaudit_logins TO public;
GRANT INSERT ON sys.pcbaudit_failed_logins TO public;
INSERT INTO pcbaudit_users VALUES ('SYS', '%');
INSERT INTO pcbaudit_users VALUES ('SYSTEM', '%');
INSERT INTO pcbaudit_users VALUES ('ABC', '%');
INSERT INTO pcbaudit_users VALUES ('DEF', '%');
COMMIT;
CREATE OR REPLACE

Thank you for your reply!
The situation is quite complicated.
I am aware that a user with DBA privileges can drop the trigger, modify it, etc.
There's an application on top of it and (i don't know why) it requires dba privileges. The point is, there are developers with access to the production database and my task is to stop them from logging in with this username.
Since I'm creating a trigger, I've obviously have no other choice. I can't change the user's password because of number of reasons, I can't deny developers' IP addresses using sqlnet.ora because they need read-only access and so on.
I realize that this is not the way that things are being done (development cycle), but I have no other choice.
So, is there any other way?
