Session Tracing problem?

when i am trying to trace a session using
dbms_system.set_sql_trace_in_session(sid,serial#,true);
command is executing succesfully but the trace file is not getting generated in udump location.
even if i try
dbms_execute.set_ev(sid,serial#,Ev=>10046,Le=>0,NM='')
its executing but trace file is not generated in udump location.
expert help is highly appreciated.
Thank you....

If you start then stop tracing a session then delete the file from the OS the trace file does not get regenerated.
what OS are you using as there are some ways round this on unix, not sure about windows.
on unix you canuse the following.
find the process id of the session being traced using
select s.sid,s.serial#,s.username,p.SPID
from v$session s,v$process p
where s.PADDR=p.ADDR and sid = &sid;
using the SPID run the following as sysdba
oradebug setospid SPID
oradebug close_trace
oradebug flush
now restart the trace.

Session Expired Problem on OAS

Hi,
I often got the error message "Session Expired" displayed on my HTML page that serves Java Servlet output after some time.
I attempted to look through my Servlet source codes but it has no problem. In fact, it runs perfectly well on JavaWebServer2.0.
This seems to be a OAS problem. I'm using Oracle Application Server 4.0.8.1. I attempted changing the Servlet Cartridge's "Max session idle time" and observe the behaviour. It appears that when "Session Expired" problem happened, my servlet class never get called. OAS simply display a "Session Expired" message on the web page.
How can I avoid this? How can ask OAS to call my servlet's doGet() to create a new session when it expired?
Anyone knows how?
null

Hi,
OAS has a limitation of 300 seconds. This value cannot be changed. See the release notes.
One possible way to get around this is to use the Oracle Supplied Session class and use the time feature in that.
This a big limitation and I am not sure why Oracle designed the product this way.

Session Tracing tab is missing.

Dear ISA Experts,
I am using ISA 5.0. When I goto logging in Admin, The session tracing tab is missing. Appreciate any pointers to display the session tracing tab to trace the session log.
Thanks!

Thanks Mark for your reply. My Java core is on SP14. SAP-SHRWEB, SAP-SHRAPP & SAP-SHRJAV are on SP11 & 12. I have gone through the note : 1090753 and noticed that the following parameters are already set.
'appinfo' and 'logfiledownload' parameters to 'true'
ForceSingleTraceFile to 'No'.
When I goto : http://hostname:50000/b2b_xyz/admin/index.jsp and logging, I see only Log configuration and not "Session Tracing". Please advice.
Thanks!
Surya.

Tracing problems

I have a tracing problem which is a bit tricky to put into words.
I placed into a.i a black and white drawing.
I did a live trace, the result seemed ok.
The problem is that the A4 tracing paper which I did the drawing on has also been traced (I think), but I only want the outlines of the actual figure I drew.
The problem arises because I want to put a grid over the figure to place it exactly in the right position and angle etc.
But the grid wont show over the white background to the drawing. That is to say the grid wont superimpose over what appears to be the edge of the traced A4 background. Maybe it isn't the A4 background, but the artboard itself - it has a blue boundary line.
I went in Artboard Edit mode and reduced the artboard to just contain the figure, but that artboard seems to sit on another artboard which is the original background.
I have no idea how to move forward with my exciting project, and it is extremely frustrating.
Does anyone have any advice?
Regards
Peter de Wit

Thanks for your response shunithD
Wow! Your suggestion about ignore white did the trick.It enabled me to do exactly what I wanted to the image - in this case place a grid over it.I cannot express how grateful I am to you for that advice.If you ever come to my cafe you can have a free cup of coffee.

Session management problems with SSO

Hi all-
I've been getting an Apex app tied to SSO as a partner app (per http://www.oracle.com/technology/products/database/application_express/howtos/sso_partner_app.html). So far, it sort of works. If I go to my apex app, it redirects me to SSO, where I authenticate and end up back in the apex app. Great. Here are two problems I've run into:
1. If I am already authenticated to SSO, and I go to my apex app (url like: http://host/pls/apex/f?p=101:1), my browser goes into an infinite redirect (url like: http://host/pls/apex/f?p=101:1:::::FSP_AFTER_LOGIN_URL:\f? p=101|1|||||FSP_AFTER_LOGIN_URL|\f?p=101|1|||||FSP_AFTER_LOGIN_URL|\f? p=101|1|||||FSP_AFTER_LOGIN_URL|\f?p=101|1|||||FSP_AFTER_LOGIN_URL|\f? p=101|1|||||FSP_AFTER_LOGIN_URL|\f?p=101|1|||||FSP_AFTER_LOGIN_URL|\f? p=101|1|||||FSP_AFTER_LOGIN_URL|\f?p=101|1|||||FSP_AFTER_LOGIN_URL|\f? p=101|1|||||FSP_AFTER_LOGIN_URL|\f?p=101|1|||||FSP_AFTER_LOGIN_URL|\f? p=101|1|||||FSP_AFTER_LOGIN_URL|\f?p=101|1|||||FSP_AFTER_LOGIN_URL|\f? p=101|1|||||FSP_AFTER_LOGIN_URL|\f?p=101|1|||||FSP_AFTER_LOGIN_URL|\f? p=101|1|||||FSP_AFTER_LOGIN_URL|\f?p=101|1|||||FSP_AFTER_LOGIN_URL|\f? p=101|1|||||FSP_AFTER_LOGIN_URL|\f?p=101|1|||||FSP_AFTER_LOGIN_URL|\f? p=101|1|\\\\\\\\\\\\\\\\\\\). To resolve, I have to clear cookies.
2. If I am using my apex app, then log out of SSO (in another browser window), I can still click around in my apex app (i.e., apex thinks I'm still authenticated).
Anyone have any thoughts? I'm wondering if I need to do something in page session management (under authentication schemes) to fix #2, but I have no clue about #1.
Thanks
Rob

Hi Scott-
Thanks for the info on #2 - I'll work on that after I get #1 sorted out, since it's the more dire problem. Here's some more info:
Apex version = 3.0.1.00.08
SSO SDK = ssosdk902.zip
I set it up as "My Application as Partner App." I used "MY_PARTNER_NAME" as SSO Partner Application Name. In the list of SSO Partner Apps on the SSO Admin page, my partner app name is also MY_PARTNER_NAME. It gives the following info:
Login URL: https://sso_host/pls/orasso/orasso.wwsso_app_admin.ls_login
Single Sign-Off URL: https://sso_host/pls/orasso/orasso.wwsso_app_admin.ls_logout
Home URL: http://apex_host/pls/apex
Success URL: http://apex_host/pls/apex/RBLICK.YOUR_PACKAGE.PROCESS_SUCCESS
Logout URL: http://apex_host/pls/apex
RBLICK is the schema owning the apex app. In there, I created a package called YOUR_PACKAGE:
create package YOUR_PACKAGE as
procedure process_success(urlc in varchar2);
end YOUR_PACKAGE;
CREATE PACKAGE BODY YOUR_PACKAGE AS
procedure process_success(urlc in varchar2) as
begin
wwv_flow_custom_auth_sso.process_success(
urlc=>urlc,
p_partner_app_name=>'MY_PARTNER_NAME');
end process_success;
END YOUR_PACKAGE;
Anything look obviously wrong to you?
Thanks!

Session timeout problem with CCA

I have developed a Client applicaiton in ASP.Net 2005 using the SOAP Api provided in Oracle CCA 8.1.3
The System details are as under:
Product – Oracle CCA 8.1.3
Server on Windows 2003 Server – Standard Edition
Web Server – BEA Weblogic 10g3
Database – Oracle 10g
Java Version – 1.5 Update 10
I am facing a problem where the users session changes every 5 Minutes 30 Seconds. I get the "Session Change" message and at this point I cannot see the Agent on the CCA Agent Monitoring screen. What I need to do now is to Reopen the session. Upon Repoening the Session I would get the same SessionId from the WebServer that I had get earlier.
Please help.

Enterprise Session Bean Problem

Dear Experts,
I have just installed Netweaver Developer Studio 7.1 Composition Environment and is doing some development on it from the tutorial in the following link
[http://help.sap.com/saphelp_nw04/helpdata/en/c3/679564e11d482f8a706b423f67e56c/content.htm|http://help.sap.com/saphelp_nw04/helpdata/en/c3/679564e11d482f8a706b423f67e56c/content.htm]
I have created a new EJB Project using the Configuration SAP EJB J2EE 1.4 Project and created a new stateless session bean Calculator.
I finished creating the session bean with all the BUSINESS METHODS, but when I expand the project node Calculator in the J2EE Explorer, I CANNOT see the Calculator.java class. All other classes such as CalculatorBean.java, CalculatorHome.java, etc are present.
This is where the problem comes, when I create the JavaBean in the Web Module I will need to access the Calculator.java class and now I cannot access it since it is missing.
Can you please guide me on how to generate the Calculator.java class in the session bean.
Points will be rewarded for correct answers.
Thanks in advance

GemXpresso JCard Manager session authentication problem

Hello!
First of all I am new in Java Card Technology and I am trying to explore the
JCard Manager environment. I am using GemSafe Xpresso Cards.
My problem is that I cant create a session between reader and card in one of my
cards. The trace in this card's authenticate prosses is:

A Card was removed from the terminal: Gemplus USB Smart Card Reader 0 from the slot: 0I think that the card came this state because my partner to this project was
issue a command by accident, and now he can't remember what he done.....
I suppose I have to change the card's KeySet from 13 (D0) to -1 (FF) but I don't know how.
Does anybody knows what i suposed to do and fix the problem??
Thank you in advance for your help, Bill....

Lets see... First of all thank you for the reply. Also I forgot to say that I use Global Platform 2.1.1 cards.
I understand that the initial keyset has been changed and I can't turn
back to keyset -1. Also my partner said that he don't remember to issued a specific command, but the only thing he remembers is that he send
an (unknown for him) APDU to the card, from the SEND APDU panel, not very wise move.
So he did not create a new key set, as I understand. I use the GET DATA command with Predefined Taq set to Key Information Data to retrieve the
informations you told me but the answer was
Get Data
-> 80 CA 00 E0 (00)
[ERROR ] <- 6A 86
[ERROR ] <- (ISO 7816-4) Wrong parameter(s) P1 P2 (Incorrect parameters P1 P2). So? what I can do now?
Thank you again in advance.... Bill

JSP Session ID Problem

I have a problem, where I am getting two separate Session Id's within the
          same browser instance. This is what I am doing:
          User sees login.jsp. A form that calls a servlet, when they do the submit.
          The first jsp and the servlet have the same Session ID. The servlet sets
          some attributes for that user, then calls
          response.sendRedirect(initial.jsp). The second jsp has a new Session ID, and
          so doesn't see any of the attributes that the servlet set.
          Am I doing something fundamentally wrong here, or is this a WLS problem? We
          are on WLS 6.0, no service packs installed.
          Thanks.

Cookies or URL encoding?                    Cookies.
          FYI. After that post, I download Service Pack 2 and applied it.
          That fixed the problem, and now a redirect doesn't generate a
          new session.
          Thanks.

Apache + 2 Tomcats session replication problem.

Greetings everyone.
Before stating the problem, let me explain how my environment is set.
I have two machines. One (PC1) running Apache (HTTP server 2.0.58)
and one instance of Tomcat (5.0.28) and another machine (PC2) with
another instance of Tomcat(5.0.28).
The Apache server
It is configured to handle static content, to redirect dynamic content to a
Tomcat instance through AJP 1.3 connector.
This process is done through the mod_jk and the workers.properties
The workers.properties file is configured to have sticky_session = True
so it assigns a SESSION_ID to the same Tomcat it was first assigned.
The workers.properties file is configured to have
sticky_session_force = True so if the Tomcat the SESSION_ID was
assigned is not available, the server answers with a 500 error.
The Tomcat servers
Both have only the AJP 1.3 connector enabled
Both have the Cluster tag from the server.xml file uncommented
and the useDirtyFlag flag set to false, for not to allow SESSION
replication between Tomcats.
The workers.properties file
workers.apache_log=C:/Apache2/logs
workers.tomcat_home=C:/Tomcat5
workers.java_home=C:/j2sdk1.4.2_13
ps=/

THE PROBLEM
I open a browser in the jk-status page to see how the Tomcat instances are
working, and both are working fine: Stat -> OK, now as the
loadbalancing factor is 1 on both Tomcats, an even alternating session
distribution is set.
While this browser is open to keep an eye on the status, I open a new
browser (B1)to connect to my Web Application, Apache answers
correctly and gives me a SESSION_ID for Tomcat instance 1 [both
instances are OK], if I make a simple refresh, my SESSION_ID is still the
same so I'm assigned to Tomcat instance 1 but this time I get an
ERROR 503 - Service unavailable but looking at the status of the
Tomcat instances both instances are still OK, no-one is down. And it
stays throwing this error for as many refreshes i do.
Now, I open a new browser (B2)and do the same process as before,
as expected, Apache now gives me a SESSION_ID for Tomcat instance 2,
repeating the same refreshing process, the error is thrown again, but still at
the jk-status page, both instances are fine.
Without closing these windows, I make a new refresh try on B1 and
even though the jk-status says both Tomcat instances are OK, the error
is still thrown. I open a third one (B3), and Apache again, correctly
gives me a new SESSION_ID for Tomcat instance 1 and answers
correctly on the first call. But once again if i repeat the refreshing process, the
error is thrown again.
Note: Using a different resolution to always keep and eye on the
instances status and using a refresh rate of 1 second for status, both
servers always were OK.
So the main problem is that somehow when the session is replicated
to the same tomcat, Apache confuses and thinks it is not available, when
asking it through the jk-status it tells it is OK
I've been trying different configurations with both Apache and Tomcat,
but there must be something missing since I don't get it to work correctly
Thanks in advance for all your helping comments.

Whew... that was quite an answer... definitely is going to help him a lot. Yeah any n00b by now should know how to use google, but that's not the point in this forums, here we are to help each other. and wether you like it or not many of us deploy applications to tomcat and stumble on this. So dont try to be cool posting this kind of answers like google this or google that if you dont have an answer please dont comment you will appear to be more noobish than you aparently are.
Well enough talking.
I found the following useful: (it comes in the server.xml of the tomcat configuration)

Enabling that entry on both machines should be enough.
Aparently the problem is not with apache. is with tomcat since it can't retain the session apache gives.

OBIEE Session Variable Problem

Hi:
OBIEE 11.1.1.5
I created a new session variable and initialization block. The default value of the variable is 1. The query for the initialization block is SELECT 123456 FROM DUAL. The query in the initialization block tested fine. I bounced the OBIEE instance.
When I use the Administration Tool to view the Session Manager, I see that the value of the variable is 123456.
The problem is in an Answers report the value of the variable is 1.
Can anyone offer a suggestion as to why the value in Answers is the default value of the variable?
Thanks.

Thanks for your reply. I agree that the expression NQ_SESSION. <<variable name>> will display the variable. And it is with this command, in Answers, that I see the default value. Only in the Admin Tool do I see the correct value assigned with the Initialization Block.
Again, my problem is I cannot display the correct assigned value in an Answer report, only the default value.

when ever i
am clik on sign out button. All session values
distroy. But when ever i click on the BACK Button in
Browser it shows all options regulary until page
refresh. How can i solve this problem.The browser is caching the page.
When you hit the back button on your browser, the browser is reading the data from the cache and not from the Http Session.
When you use HttpSessions, it is a good practice to prevent browsers from caching your page.
Caching mechanism is browser dependent and HTTP protocol version dependent , do some research on how you could prevent a page from being cached and add the code directly in the JSP page which you don't want to be cached.

HP T510 Citrix session disconnect problem

Hello, I had problem with HP T510 (Thinpro Image 5.2/citrix receiver 13.1, Xenapp 6.5 on serveur 2008 R2). After direct ICA connexion on published desktop, the connexion drop and the user came back to the Thinpro OS. The problem seems to be with Lotus Notes 6.5 when they click on “New memo” or “Address” but not every time. After lost connexion the user must enter the password on Thinpro ICA connexion to retrieve is Windows session (session just lock not logout). Nothing special on server log. I think the ICA session send signal to terminal to disconnect. Thanks you Eric

We are having the exact same issue with our T510s, also on ThinPro 5.2, latest image. However, we do not use Lotus Notes, and there are no "crashes" happening, they simply lose connection and get their sessions back when they re-login. We have a T520 running W7ES, and some T5740s running WES9 with no problems. It is only these T510s on ThinPro 5.2. Are yours using wireless by the way? All of ours that have the issue are wireless. We have a few T510s that are on a wired connection that I haven't seen the problem on, but I will need to verify with the users. Between this and the application icons being blank I posted about here, I am a bit less than impressed with ThinPro 5.2...

Static methods in Session Beans problem

Can a Stateful Session Bean have a static method?
public static String foo();
I tried to add a static method to a Stateful Session bean but had two problems:
When I tried to add the static modifier to the Remote interface:
static String foo();
I got the following error message:
Error(12,17): modifier static not allowed here
When I tried to compile code calling this function :
MyClass.foo();
I got this message:
Error(795,42): non-static method getNewSuffix(java.lang.String) cannot be referenced from a static context
Even though a static method was compiled in this class. I assume it can't find the static modifier in the Remote interface which wasn't allowed. Are static methods allowed in EJB's at all?

dear friend,
1) Interfaces may not contain static functions!
2) EJBs doesnt support static methods !
Maybe you should go and learn more about Java and EJB's ?

Session variable problem : equality comparisons

I have defined the following session variable returning the error *"[nQSError: 10058] A general error has occurred. [nQSError: 42040] The session variable, NQ_SESSION.TEST, is defined as Row-Wise Initialization. It is restricted to usage with equality comparisons. (HY000)"*
select 'TEST', organisatie_nummer
from st_organisatie
where (select case when regio = -1 then 1 else
regio_nummer end
from st_gebruikers
where upper(gebruiker) = upper('VALUEOF(NQ_SESSION.USER)')) =
(select case when regio = -1 then '1' else regio end
from st_gebruikers
where upper(gebruiker) = upper('VALUEOF(NQ_SESSION.USER)'))
Why this setup...a user can have access to 1 region or 'ALL' region. To make the 'ALL' available a dummy records has been inserted with a value of -1.
There's no problem to retrieve the region (another session variable), it returns '%' in case a user has all regions or the region name itself.
But i wanted to use this variable to retrieve the organisations linked to a region, but using a like statement or the query above isn't possible as it always returns the same error.
Someone any idea how to resolve this?!
Txs,
Andy

[nQSError: 10058] A general error has occurred. [nQSError: 42040] The session variable, NQ_SESSION.ORGANISATIE, is defined as Row-Wise Initialization. It is restricted to usage with equality comparisons. (HY000)
I transformed my query like this, I don't have any clue why this isn't working...if I run this sql statement it works perfect but not in OBi
select 'ORGANISATIE', organisatie_nummer
from st_organisatie
,(select gebruiker,regio from st_gebruikers) b
where case when b.regio = -1 then 1 else regio_nummer end
like
case when b.regio = -1 then '%' else b.regio end
and upper(gebruiker) = upper(':USER')
