Use DBMS_SUPPORT to set trace in another users session
Next use the interface to again set trace for SCOTT's session that we found earlier. here it is:
     SQL> exec dbms_support.start_trace_in_session(10,20,waits=>true,binds=>false);
     PL/SQL procedure successfully completed.
     SQL> -- execute some code
     SQL> exec dbms_support.stop_trace_in_session(10,20);
     PL/SQL procedure successfully completed.

How to trace someone else's session

Hello,
How do I trace a user's session. A user is complaining of an error and I want to trace the user's session. Thank you.

You will need to get the sid and the serial# from v$session. Once you have them, issue one of the following:
You can use dbms_support to enable and disable the trace. If it is not installed, you will need run $ORACLE_HOME/rdbms/admin/dbmssupp.sql
To enable a level 1 trace, like setting sql_trace=true
exec dbms_support.start_trace_in_session(<sid>,<serial#>);
To enable trace with binds
exec dbms_support.start_trace_in_session(<sid>,<serial#>,binds=true);
Toe enable trace with binds and waits
exec dbms_support.start_trace_in_session(<sid>,<serial#>,waits=true,binds=true);
To stop tracing
exec dbms_support.stop_trace_in_session(<sid>,<serial#>);
It is better to end the session instead of disabling the trace. Some cursor stat lines may not be written to the trace when disabling trace that would have been written if the session terminated.

How to trace other user's session?

Dear Experts,
I would like to trace other user's session, I am on Oracle 10g R2 (10.2.0.4) on a Windows box. I did search on google and found tons of articles explaining about tracing techniques. But unfortunately, trace file is not getting generated in my case. Below are the steps I am following:

You must be using shared server.
You can verify this by referring to the SERVER column of v$session.
In shared server several servers will execute your code, so that's why you don't find a trace file.
The method described in this article should work in your case also:

How to trace for multiple user sessions?

Hello -
I have a username from the app that has 7 connections to the database. What is the easiest way that I can run the 10046 trace event across all 7 sessions, and also name the trace files so they can be recognized in user_dump?
Thanks in advance!

Check what sid and serial# has session:
select sid, serial# from sys.v_$session where ...
start tracing session with:
execute dbms_system.set_sql_trace_in_session(sid, serial#, true);
stop tracing with
execute dbms_system.set_sql_trace_in_session(sid, serial#, false);
Look into udump directory for trace files:
The default name for a trace files is INSTANCE_PID_ora_TRACEID.trc where:
INSTANCE is the name of the Oracle instance,
PID is the operating system process ID (V$PROCESS.OSPID); and
TRACEID is a character string of your choosing.

How do i start an Oracle Trace? For a currently running session?

How do i start an Oracle Trace? For a currently running session? How do i read it?

How do i read it? Ohh forgot this one. That tracing will create a tracefile in udump directory and you need to run tkprof to parse that trace file so that you can read it. To find the udump dir type "show parameter user_dump_dest" at sqlplus prompt and then run tkprof like (from OS prompt):
tkprof file_name.trc file_name.txt sys=no
Type only tkprof for more option of this tool.

When closing FF and then try to go back on, a msg. says FF is already running, but not responding, to open new window you must first close the existing window or restart system. How do i close without restarting?

'This happens after a FF session is ended and am back on my desktop screen. If I then try to go back online a message says that FF is already running but is not responding. To open a new session you must first close the existing process or restart your system. I have to restart the computer to before it allows me to go back on. How can I close the session and then open a new one without rebooting???

Hey GreenViking,
You can kill the process manually by right clicking in the task bar (next to the time and date) and opening the task manager.
[https://support.mozilla.com/en-US/kb/Firefox%20hangs#w_firefox-hangs-when-you-quit-it This article] has some information about Firefox hanging when you try to close it.
Hope that helps!

Firefox claims that it is already running and will not let me start a new session after closing out

I've been having this problem intermittently on both my Dell XPS 8000 and my HP nx7400 laptop. The Dell is running the latest version of Windows 7 Pro and the HP is running XP Pro (fully updated). After closing out of a Firefox session and running other apps, Firefox will not let me initiate another session, saying that "Firefox is already running... Please close the session..." That's not an exact quote, but you get the idea. CTRL-ALT-DEL and all other conventional means don't work and I am forced to reboot the system. This is a royal pain.. and I need some pain relief! Any suggestions? I may revert to an earlier version of Firefox until I see a solution... can't hurt, but I really like 4.0 and I don't look at going backwards as "progress."
Thanks.
Tom

ITunes could not sync information to the iPod "...." because another sync session was already running.

Normally, syncing my iPod Touch is no problem. However, last time I tried to sync, the process hung up and even after half an hour the progress bar would not finish. I ended up having to force quit iTunes. Now when I try to sync I get 2 messages: the first says "iTunes could not back up the iPod "......" because a session could not be started with the iPod." as soon as I close that message another appears: "iTunes could not sync information to the iPod "......." because another sync session was already running."
There seems to be a half finished sync file saved somewhere and a new one cannot be started. However, I can't continue the partial one either so I'm stuck.
Other than that my iPod Touch 4 is operating normally. Syncing with Mac Book Pro.
How do I fix this problem?

WHat do yo meanby rebooting?
Is is a reset like defined in the users guide:
Reset iPod touch: Press and hold the On/Off Sleep/Wake button and the Home
button at the same time for at least ten seconds, until the Apple logo appears.

How to check if web application already running?

Is it any way to check, if a web application is already running on clients computer. In other words how to prevent users to opens second instance of the same running application??

Not sure what you mean.
The application (scope) only runs once. A user cannot force another application scope to open up, ColdFusion controls this. If no request is made within the timespan set for the application timeout, then the next request fires off the onApplicationStar() BIF automatically before the request BIFs are executed.
If you mean that you don't want them to have more than 1 browser open to the same website, I'm not sure that's going to cause any issues; as what was said before, the web is stateless. ie:
If I open Chrome, and in Tab 1 I goto home.cfm and in Tab 2 I goto home.cfm the to ColdFusion, it basically sees 2 requests to home.cfm made from (in essence) the same person (even though it doesn't know that until you implement some form of user tracking).
But even if a person logs into a website, the session data is shared for the browser or session (depending in how your sessions are setup) So even if he logs in on Tab 1, the next time he goes anywhere in Tab 2, it'll be when he's logged in. The 2 tabs share the same session data.

When I attempt to open firefox an error message appears telling me that firefox is already running, but I can't find it running. How do I do so or in any case close the already running Firefox process?

When I attempt to open Firefox instead of Firefox opening, an error message appears saying "Firefox is already running but isn't responding. To open another window please close the existing Firefox process or restart the system.", but I can't find that process of Firefox in order to kill it, and after restarting the system there is still the problem. I have found an emergency fix to at least get online, and that is to use"Firefox_Profile_Manager" in the start menu's "run" start menu, but the
Firefox that then opens is that one doesn't carry over what I had in my bookmarks but starts bookmarks anew.

Sounds like it is hanging when you exit and later try to restart Firefox.

How can I stop from getting the "Firefox is already running" error message when trying to open links and FF has already been opened through a symbolic link?

I use symbolic links and program shortcuts as a way to easily open different Firefox profiles ie. one for casual/personal use and another for work. This works well, but I get the "Firefox is already running, but is not responding" error message if I try to open external links with FF as my default browser. FF is actually open and running fine, but I guess it doesn't acknowledge this fact because of how I'm originally starting the process.
I wasn't able to add the symbolically linked executables to the default program pane. Is there a way to bypass this error or other way to fix this?
The solution to the question linked below is what I'm using to open the different FF profiles.
http://superuser.com/questions/255312/pin-same-app-multiple-times-in-windows-7

hello, this is probably happening when you run the default profile with the -no-remote switch.

After closing out, FF will not restart, says it is already running forcing me to reboot. I have removed and re-installed FF and still get the same message when trying to open the internet using FF. How can this be fixed?

When I close out Firefox, and return later to use the internet, I click on Firefox and it gives me a message stating that Firefox is already running and needs to be closed before restarting or reboot my system. This occurs every time Firefox is closed and attempt to re-start it,,, not only at times,,,, EVERY time.
I have tried removing Firefox from my system and re-installing to fix this issue however,,, this did not work. After re-installing, I still get the same message when attempting to restart Firefox.
I have also tried Ctrl, Alt, delete to open the task manager and find there is no task to close.
I do not have any problems when using IE, I prefer to use Firefox as it is faster and crashes less than IE.
I am very frustrated at having to reboot my system each time I want to use the internet.
How can this problem be repaired?

There are various causes for this error, see [[Firefox is already running but is not responding]] for details.
