Stripchart trace name

Hello,
Is it possible to change the legend trace name in a strip chart?
If yes, how?
Exemple : change "Trace 1" name to "Humidity Sensor"
Thanks
Solved!

Hi Goncalo,
Yes you can with the SetTraceAttribute function:
SetTraceAttribute (panelHandle, PANEL_STRIPCHART, 1, ATTR_TRACE_LG_TEXT, "Humidity Sensor");

How to scan 'immediate trace name SYSTEMSTATE level 10' trace files?

Hi ,my 20 TB of database is hanging and my manager told me to run the following system state dump and anaylse the trace file to see which processes etc are hanging the database.
SQL>alter session set events 'immediate trace name SYSTEMSTATE level 10';
I got 2 trace files which are quite large....not sure what to look into.....can anybody plz suggest what to see if in them if database is not responsing
Thanks
gagan

If you dump a couple of hanganalyze every 60 seconds or so. You will be able to see wait chains and identify sessions that are progressing(slow) and those that aren't(hung). Then you can reference this information with the process information in the system state dump. A level 3 or 4 is ok for what you want. Still, if you are not sure where to look in the first place, best to log a SR with Oracle.

Alter system set events '1460 trace name errorstack off';

Hi,
if I issue :
alter system set events '1460 trace name errorstack off';
Is there any query that can make me sur and help me to see the value of events '1460' ?
Thank you.

Is there any query that can make me sur and help me to see the value of events '1460' ?No one, because you turned off the trace level.

Enabling alter system set events '1422 trace name errorstack level 1'

Hello, please i need some help:
I need to set events '1422 trace name errorstack level 1',
where does this sentence generate the trace logs?.
Once collected the information how do i disable it?
Thanks in advance.

Normally user dumps are written to the udump database parameter destination. See v$spparameter or v$parameter.
You can set the level to "0" (zero) to set tracing off.

Help with "alter system set events = '1000 trace name ERRORSTACK level 3'"

Hello.
I am trying to find out wich sql code is creating the error ORA-01000 in my application (database release is 9.2.0.7). I have read this http://www.orafaq.com/node/758 and there they suggest doing this:
Sometimes you will need to get a full stack trace of the problem by setting a trace for ORA-1000 as in:
alter system set events = '1000 trace name ERRORSTACK level 3'
or...
alter session set events = '1000 trace name ERRORSTACK level 3'
Then set open_cursors to a low enough number to catch the open cursor voilator in your net.I have no idea about this traces, so these are my questions:
1. Do those commands force a trace every time the ORA-01000 errors rises in every session? (I have forced the ORA-01000 error in one sqplusl session after I wrote "alter session set events = '1000 trace name ERRORSTACK level 3'" in another sqlplus session)
2. What does level 3 mean?
3. I see that in the dump/user directory I have several trace files, how can I know which error traces are enabled in my db?
4. How do I disable the traces once I find out to solve the problem?
5. How do I identify in the traces the ORA-1000 error?
Thanks in advance.

Thanks for all the answers.
What am I doing bad? I have tried ti find out what traces are enabled, and there seems to be none.

Trace name graph xy

Hi,
How can i set the name of a trace (as an input control) in the Graph XY display ?
i looked in the property nodes but i didn't find the solution.
Would you help me please ?
Samer,

Thanks, i have another problem.
In the VI enclosed i have a listbox of URLs. My goal is that each time i press on an element on the listbox i get a new plot in the graph XY(corresponding to theURL); but i want that the properties of a plot (color, style) remain for the same plot but each time i choose an element i see the properties of a plot transfered to the new plot.
Could u tell me where is the problem in my VI ?

How to trace an application in Oracle 10g

Hi,
I want to trace a complete application in Oracle 10g end-to-end.
Here is the scenario,
The are two systems:
System A: Oracle 10g server
System B: Windows server
The application runs on system B.
How do I trace the complete application in oracle 10g?
I read about the trcsess tool but will like to know if there is a way to collate all *.trc produced by the application.
Thanks in advance!
-Thanks
Karthik

Tracing the Oracle transactions is easy, but you need to decide what level of trace you want and identify the database sessions to trace.
Tracing can generate huge amounts of logs, so think carefully if you really need to do this.
The tracing will only capture the database transactions. It won't track what happens in the application (e.g mouse clicks etc)
Options to enable tracing :-
-- ALTER SESSION
alter session set tracefile_identifier = 'robert_trace'; # so that the trace files from this session are easily identified
alter session set events '10046 trace name context forever, level 8';
-- ALTER SYSTEM
alter system set sql_trace=true;
-- DBMS_SESSION
exec dbms_session.set_sql_trace(sql_trace => TRUE);
-- DBMS_SUPPORT
exec dbms_support.start_trace(waits=>TRUE, binds=>FALSE);
-- DBMS_SYSTEM
exec sys.dbms_system.set_ev(72,21237,10046,12,'');
-- ORADEBUG
select username, spid from v$process;
ORADEBUG SETOSPID 21237
ORADEBUG EVENT 10046 TRACE NAME CONTEXT FOREVER, LEVEL 12
-- DBMS_MONITOR
exec dbms_monitor.session_trace_enable(session_id=>75, serial_num=>21237);

How to trace an error

Dear all,
How to trace a purticular error ?
from metalink
Diagnose the issue by running the following trace
alter system set events '1775 trace name ERRORSTACK level 3';
Redo the import and reproduce the error. The trace file should be in the
USER_DUMP_DEST directory.
alter system set events '1775 trace name errorstack off';
Trace file will show something like the following:
ksedmp: internal or fatal error
ORA-01775: looping chain of synonyms
Current SQL statement for this session:
SELECT COUNT(*) FROM SYS_IMPORT_TABLE_01
I am getting the same ora 01775 error. But when I am tracing, I am not getting any result in my udump. Is there any other setting do I have to make to get the trace file?
Thanks

Your question can not be answered.
Not only you don't include a version (this seems to be too difficult for most posters here), but you also include ambiguous sentences like 'When I am tracing'.
This results in the question 'did you issue the alter system command and was it successful?'
As far as I am aware the syntax is
alter system set events='<errornum> trace name errorstack level 3';
There are no other 'settings'
The only other solution is to set up an afterserver error trigger.
Works like a charm, 8i onwards.
You uncover way too many things you don't even want to know!

How to trace a USER in oracle?

Hi Sir,
I have a rquirement that I need to Trace a session created through the Application. The only data I have is that I know the application will connect to a Database schema and nothing else. How is it possilbe that I can create a trace file for it.
Also is it possilble, that i can trace complete user. how to find all the trace as it create number of process inturn number of trace, how do I find it and combine. I read the documentation but can't understand it clearly?
Any help will be great.

sanora600 wrote:
Aman, thanks for replying. This is the problem, they have not implemented dbms_application_info.
That is the reason I want to know how to trace user(all session of a schema) and combine all the session generated trace(something like trcsess) and then generate tkprof. I am on Oracle 10g.Well, first off, users connect to databases, they don't connect to schemas. And as a follow on, users have sessions, schemas don't.
That said, you might investigate a logon trigger that initiates a 1046 trace. Something like this:
-- create a logon trigger for capturing extended trace data
-- NOTE: must be run as SYS
-- NOTE: Be sure to change both occurances of the target username
-- ('user = xxx' and 'TRACEFILE_IDENTIFIER=') to the
-- correct value for the session you want to trace.
create or replace trigger logon_trigger
after logon on database
begin
if (user = 'SCOTT' ) then
execute immediate 'ALTER SESSION SET TRACEFILE_IDENTIFIER=''SCOTT_APP''';
execute immediate 'alter session set timed_statistics=true';
execute immediate 'ALTER SESSION SET EVENTS ''10046 TRACE NAME CONTEXT FOREVER, LEVEL 12''';
end if;
exception
when others then
null;
end;
end;
Of course, you can play around with the 'if' condition, and delete or disable the trigger when it is no longer needed. The resulting trace file can be run through tkprof.

Add (name of bill-to-party )column in f-58 (form: F110_IN_AVIS)

Hi, I'd like to ask ..how to show the name of Bill-to-party (add column) in the form F110_IN_AVIS in f-58
I'm confuse about it.
i just know REGUP-XBLNR is the invoice no...that i can trace the bill-to-party no and trace name.
but should I need to write a program to get this form. (don't use its build-in program).
do i have any other ways ..that just need to modify the form only?
hope and Thx for your help

Hi Soobhany Parvez,
Please let me know if the update will be carry out successfully as currently I'm not very sure on steps involved on your side:
1. VA02 & goto the Partners tab at the header level.
2. Select the ship-to party by highlighting the row & click on the 'Business Partner Master Data' button (next to determination log button) which is located at the bottom of the screen.
3. System should display 'General Data' of the Customer Master screen. Click on the 'Display->Change' button & proceed with updating the changes then follow by clicking the Save button.
4. Changes is updated if you recheck from sales transaction.
If the above is not the same you have experience, do not hesitate to let me know & I'm interested to find out the steps you have taken to check further.
Hope this help. Thanks.
Best regards,
HC.

How does I read a HWS file that contains 2 traces, in labview? (error -21508)

Dear experts,
I have been using a PXI-5105 acquisition card to save data from 2 channels at the same time (coming from different sensors).
Up to now I have been reading the files in Matlab, taking into consideration the group name, the trace name and the coefficients of each channel. I was able to do the post-processing of the data in Matlab. I attach an example of the kind of files I'm handling if it helps, inside a zip.
Now I would like to implement this post-processing (FFT, etc.) in Labview. I have tried to use a couple of examples such as "hws_low_level_read.vi" or even the HI-HWS Express load utility to check the file, but it seems difficult to read it because of the 2 channels saved inside the same file.
The error -21508 appears at the "niHWS Get Wfm reference.vi". That refers to:
Error -21508 occurred at niHWS Get Wfm Reference.vi
Possible reason(s): NIHWS: There is no group in the file that matches the provided group name
And it seems odd to me, as I'm using the same name for group (wfm_group0) and trace(vector0) than I was using in Matlab.
Anything I'm missing? Any hint on how to read it in any way?
Thanks you very much in advance for your help
Best regards

Dear all,
I have been struggling with that problem today and I just wanted to post here how I have finally found a way to read the data.
It is so easy that I'm a bit ashamed, but I think it is worthy to answer in case anyone would need it.
The "niHWS Get wfm Reference" is asking for a Group Name and for a waveform name. I have used the "niHWS Get Group Name" and the "niHWS Get wfm Name". Both have direct outputs (strings) with the information that "niHWS Get wfm Reference" understands. You can directly link them.
But actually, in the reading of the data I found that the group name doesn't need to be fulfilled and the waveform name is "0" or "1" in cae you have 2 channels.
So, you see, it was very easy for my HWS file: put a control and select "0" or "1" for waveform name. The simpler the better, jejeje.
I hope it helps. And sorry for opening the question I'm now answering myself. I was completely lost yesterday.
Best regards

Traces are not being generated

hi,
I have 9.1.0.8 database on windows 2003 (32 bit). I am suing following statement to start system wide tracing but i don't see any tarces being generated at user_dump_dest location. any idea what is going wrong and what thing i am missing?
ALTER SYSTEM SET EVENTS '10046 trace name context forever, level 8';
Timed_statistics is set to true
Salman

Strange - what you have done should work, it works on my 10G database OK.
Sorry but dont have much else to add ...
I presume that if you just do it at session level it works ok?
ALTER SESSION SET EVENTS '10046 trace name context forever, level 8';
