How to identify current session id (SID)?

How can a user identify their current session id if auditing is not enabled and account has connect role only? select * from v$mystat where rownum = 1; Fails (ora-942).

I think this is going to be difficult. I've included a completely convoluted idea I thought of using just CONNECT accessible objects (looking on a 9.2 database). You can't make this a stored procedure though (no direct privileges). I'll be interested to see if someone can come up with something easier.
declare
rindex binary_integer := dbms_application_info.set_session_longops_nohint;
slno binary_integer;
usid varchar2(24) := dbms_session.unique_session_id;
mysid number;
begin
dbms_application_info.set_session_longops(rindex, slno, 'get_sid:' || usid);
select sid
into mysid
from v$session_longops

2. made change to listner.ora and tnsnames.ora file and able tnsping also.
- tnsping extproc_connection_data
3. ssoldap.sql also ran in portal30_sso schema with all LDAP information.

my questions is Iplanet(LDAP) can integrate with Portal or any steps missed.
Please help in this regard,

You may want to use ssoxoid.pkb package that comes with Portal/Login Server 3.0.9 which simplifies the configuration.
Also, you will not have to run the external procdure listener. Please refer to the Login Server Admin. guide for more details.
NOTE:
the 3.0.9.8.0 version of ssoxoid.pkb is not good. You need to download 3.0.9.8.2 patch and get the ssoxoid.pkb file from there.
Also, you may want to turn on debug for SSO Server to see debug msg.

Database Audit

hi,
Our application need to keep track of every update done to the table by the user who has logged in. We have written a trigger which fetches the unique Oracle SessionId and the user id logged in. But we are facing a strange problem. In our table's update trigger on each row when we specify
Select sys_context('USERENV','SESSIONID') into v_SessionID from dual;
in the place of
Select dbms_session.unique_session_id Into v_SessionID from dual;
on each update it works fine. But if we try the second one (which fetches the session id using dbms_session package) we are getting teh following error on each update
"ORA-01422: exact fetch returns more than requested number of rows ORA-06512: at "IPAMSADM.TRIG_ITEM_PERS_UPDATE_ROW", line 11 ORA-04088: error during execution of trigger 'IPAMSADM.TRIG_ITEM_PERS_UPDATE_ROW' "
Though the use of sys_context helps me to solve the issue I'm kinda curious to know the context in which these 2 are applied.
Your reply is really appreciated.

Hi,
You can check the entry for Drop Tablespace in the alert log file. You can safely recreate the temp tablespace as it does not store any permanant objects. To prevent such activity in the future or to get some more info on the activity you can enable Oracle auditing for all the DDL statements that get fired against the database.

DBMS_SESSION.SET_ROLE in Forms 6

I created a role called "DATA_ENTRY" and altered it so that the DEFAULT_ROLE property set to "NO".
I have an application with a customized menu that uses roles in menu security. The role is in the list of menu roles. The application has multiple forms, only one of which is open at a time, with a Main form as the point of entry. Navigation is implemented only through the menu.
I added code to the PRE-FORM trigger that uses DBMS_SESSION.SET_ROLE to enable the role. With the code in place, the screen opens and the menu is enabled. If I comment out the code, the Menu fails when I open the Main form - which is what I'd expect.
However, when I navigate to another screen, it acts like the Main form does with the code commented out - i.e., the Menu fails (doesn't load).
Since DBMS_SESSION.SET_ROLE is a session-level command, I wouldn't think I'd have to include it in every screen.
I'd appreciate any help. Thanks.

Could it be that you are opening your other screen in SESSION_MODE=SESSION ?The forms are opened using New_Form builtin, so the SESSION_MODE doesn't apply.
In the post-form trigger of the main screen, the role that I enable in the pre-form trigger is shown as disabled. So, of
course, it's disabled in the new screen as well.
I also verified that the UNIQUE_SESSION_ID is the same in pre-form and post_form on both screens.

Using dbms_session.reset_package inside procedure

How to use the line dbms_session.reset_package in a procedure.
I used execute immediate 'dbms_session.reset_package' , but it is not executing.
How to execute it
Plese help me

What do you think should happen when you execute that package?
Or have you yet again ignored even bothering to RFTM the Oracle® Database PL/SQL Packages and Types Reference to see just what this call does?
Quote:
This procedure de-instantiates all packages in this session. It frees the package state.
Memory used for caching the execution state is associated with all PL/SQL functions, procedures, and packages that were run in a session.
For packages, this collection of memory holds the current values of package variables and controls the cache of cursors opened by the respective PL/SQL programs. A call to RESET_PACKAGE frees the memory associated with each of the previously run PL/SQL programs from the session, and, consequently, clears the current values of any package globals and closes any cached cursors.
If you expect PGA to decrease, it will not. Dynamic memory allocation at o/s kernel does not work in such a simplistic way. Memory malloc'ed by an application (like an Oracle dedicated or shared server process) may only be actually freed by the kernel when the process terminates.

"date format not recognised" in DBMS_SESSION, on page over db_link

Hi,
I have an Apex 4.0 page which has a region that gets data constituted from a connection across a database link.
The host database is 11.1.0.6 and the remote database is 9.0.1. (Both Standard Edition)
I am using EPG.
Intermittently, I receive the following error (having turned debugging on):
Wed, 25 Aug 2010 10:21:53 GMT
ORA-20867: ORA-01821: date format not recognized
ORA-02063: preceding line from CLIFF
ORA-06512: at "SYS.DBMS_SESSION", line 157
ORA-06512: at "APEX_040000.WWV_FLOW_LANG", line 387
ORA-06512: at "APEX_040000.WWV_FLOW", line 9284
ORA-06512: at "APEX_040000.F", line 267
ORA-06512: at "APEX_040000.F", line 294
ORA-06512: at line 30
I'm somewhat confused as to what is causing the generation of this error.
After receiving this error, anything I else that I do that involves building 'pages' works perfectly fine. I can login/out, no problems.
However, if I try and RUN any page within my application thereafter (all of these access local DB information apart the 1 that generates the error), I continue to receive exactly the same error - no matter which page I am trying to access.
Help?
- Tony.

Hi Patrick,
No. I haven't yet applied the patchset. May do that this afternoon now.
I don't believe I've manually set any date formats anywhere. Just entered the Builder with default options (apart from choosing a theme) and away I went!!
What surprises me is that the application has no problems viewing all the data. The functionality all seems fine. I had this working on a previous setup for months,. without any problems, using version 3.2. (This wasn't migrated though, this was a rebuild from scratch.)
From further "tests", the error seems to occur when I edit the page that involves the remote data.
Normally, a user would land on the page from having used a hyperlink column on a previous page's classic report region.
The point at which it all starts to go wrong is if I connect to the page as normal, but then EDIT the page, and then try and re-run it.
The problem with the date format then re-occurs repetitively, no matter which page I try and view. Sometimes pages will load some components, but then generate odd errors with others. e.g. I have a small series of 3 dial charts, all with slightly varying SQL series (same SQL, slightly different where clause). Now I am seeing that 1 may load and 2 may give odd flash errors...
Right now, I just tried to Export my application - and I still got given the date format error!! Sub-sequent retries allowed the operation to complete successfully.
The only way I seem to be able to eradicate the recurring errors is to kill all the currently connected ANONYMOUS users in the DB, and then relog to the application.

Dbms_session.set_context from JDBC fails mysteriously, how can I trap it ?

Hi gurus,
Our ADF application connect via JDBC to Oracle DB and using VPD .
This is done by executing dbms_session.set_context('vpd_new','loc_code', pLocCode) at the beginning of the session.
Mysteriously, all loc_code succeed to be set resulting in the VPD is correctly working, EXCEPT for one loc_code, it doesn't work.
dbms_session.set_context('vpd_new','loc_code', '010') -> works
dbms_session.set_context('vpd_new','loc_code', '020') -> works
dbms_session.set_context('vpd_new','loc_code', '030') -> works
dbms_session.set_context('vpd_new','loc_code', '061') -> DOES NOT work.
-> and it Seems to use the last value set, i.e : '030'
Other loc_code also works perfectly.
how can I know what happen when the application execute : dbms_session.set_context('vpd_new','loc_code', '061')
Why does it fail ?
Can I know what command is really sent to the Database ?
or can it be other reason ?
Thank you for your help,

Dbms_session.set_sql_trace(true) in PL/SQL Code to trace execution

Hi,
I'm working on some legacy PL/SQL Code with the objective of tuning. I added the following to the PL/SQL Body so that I can trace the execution and identify low-hanging-fruit that can be tuned.
I added the following after the BEGIN section of the PL/SQL body:
trace_process_flow_info_sp( this procedure captures the parameters passed into the procedure of the package body);
execute immediate 'alter session set events '||''''||'10046 trace name context forever, level 12'||'''';
dbms_session.set_sql_trace(true);
My objective is to capture the execution of the code, capture the bind variable values, however I am not seeing the bind values in either tkprof or the Trace Analyzer.
Any Ideas on how to see the Bind Variable Values?
Thanks

Level 0 means no binds.Are you sure that this level is available?
According to note 115675.1 there are only four
possible levels (1,4,8,12)Hmmm it seems you are right.
SQL> conn xxx/xxx@xxx
Connected.
SQL> ed
Wrote file afiedt.buf
1* alter session set events '10046 trace name context forever, level 0'
SQL> /
ERROR:
ORA-02194: event specification syntax error 231 (minor error 283) near '0'
SQL> ed
Wrote file afiedt.buf
1* alter session set events '10046 trace name context forever, level 1'
SQL> /
Session altered.
SQL> The same results for 9.2.0.7.0 and 10.2.0.1.0
So OK a correction dbms_session.set_sql_trace(true) means level 1, but anyway it means no binds.
Thank you for your correction, should go and update my article!

Reg: dbms_session package

Hai, Did anybody encounter this kind of problem?
I have a secured role assigned to the users that will be enforced using dbms_session.set_role package. Till date it is working fine, but when the database profile had started me giving the message - Password will expire within x days, the role is not functioning properly. Are they related with each other ?
Can anybody please help me regarding this..

Hai, Thank you for your reply,
This is implemented as follows,
1.created a secure role in the database.
2.altered the user default all except the secure role.
3.when the user logs in, the role is enabled using dbms_session.set_role.
This was working fine till date. Also working fine with the newly created users.
4.Now, the database profile had started giving the grace period when the user logs in along with the ORA-6512 sys.dbms_session. Now the role is not being enforced.
Is there any relation between this profile and secure roles?
