Debugging - Wht is CALL STACK, OVERVIEW etc.

Hi Experts,
As am working with user-exits for VA01, VL01N etc., When I want to debug these VA01, VL01N tx, as we know, there is huge SAP code, so ,i guess, in this regard, CALL STACK, OVERVIEW, Menu--->debugging updation etc, helps to trace out our requirement!! so, pls, clarify that, in debugging mode,
1) How Can I use CALL STACK or Wht is the role of it?
2) How Can I use OVERVIEW or Wht is the role of it?
3) How Can I use mENU-->Debugging Updation or Wht is the role of it?
Thanq.

Hi Srikhar,
Please refer to the below chart for the uses and the roles of all the modes in debugging.
Display Modes Available Using Pushbuttons
Fields
The scrollable field display contains the contents of up to eight fields. The contents of the three most important system fields are always displayed. This is the default display mode in the Debugger. See also:
Processing Fields
Table
Displays the contents of an internal table. This mode allows you to display and edit the entries in an internal table. also:
Processing Internal Tables
Breakpoints
A scrollable display containing up to 30 breakpoints. Next to each breakpoint is a counter. You can also delete breakpoints in this display. See also:
Managing Dynamic Breakpoints
Watchpoints
You can set a watchpoint for a field so that the program is interrupted whenever the value of that field changes. This display mode contains a list of watchpoints, the fields and programs to which they are assigned, the current values of the fields, and the conditions upon which the watchpoint is activated. See also:
Setting Watchpoints
Calls
This mode displays the current sequence of events, and the sequence of calls up to the current breakpoint. The last active call is displayed at the top of the list; previous calls are listed in reverse chronological order. When an event (for example, START-OF-SELECTION) concludes, it is deleted from the display.
Overview
This mode displays the structure of the program. It lists its events, subroutines, and modules, and shows which sections belong to which events. It also displays the section currently being processed.
Settings
This mode displays the current Debugger settings. You can change the settings by selecting or deselecting various options. For further information, refer to:
Settings and Warnings
In case you have any further clarifications,do let me know.

The ABAP call stack was: SYSTEM-EXIT of program BBPGLOBAL

Hi
We are using SRM 5.0. We are facing a strange problem. We are able to see the initial screen of SRM EBP in the browser. But once the user name and password are provided the system goes for a dump with the following error:
The following error text was processed in the system SS0 : System error
The error occurred on the application server <Server Name> and in the work process 0 .
The termination type was: ABORT_MESSAGE_STATE
The ABAP call stack was: SYSTEM-EXIT of program BBPGLOBAL
SM21 Log:
Short Text
 Transaction Canceled &9&9&5 ( &a &b &c &d &e &f &g &h &i )
 The transaction has been terminated. This may be caused by a
 termination message from the application (MESSAGE Axxx) or by an error
 detected by the SAP System due to which it makes no sense to proceed
 with the transaction. The actual reason for the termination is
 indicated by the T100 message and the parameters.

Besides I tried this note: 790727 as well, still I get the same error.
Any help would be highly appreciated.

Hi
Please do the following steps.
When you are using the Internal ITS,you need not run the report W3_PUBLISH_SERVICES.(only SIAC_PUBLISH_ALL_INT )
ALso pls check the foll:
-->activate the services through SICF tcode.
> Go to SICF transaction and activate the whole tree under the node Default host>sap>bc>gui>sap>its.
>Also maintain the settings in SE80>utilities>settings>internet transaction server-->test service/Publish. (BBPSTART , BBPGLOBAL etc)
Table TWPURLSVR should have entries for the / SRM server line as well as gui and web server.
Could you please review again the following steps ?
Did you check that ICM was working correctly (Transaction - SMICM) ?
1-Activate the necessary ICF services
With transaction SICF and locate the
services by path
/sap/public/bc/its/mimes
/sap/bc/gui/sap/its/webgui
2- Publish the IAC Services
With Transaction SE80 locate from
the menu Utilities -> Settings ->
Internet Transaction Server (Tab) ->
Publish (Tab) and set On Selected
Site = INTERNAL.
3- Locate the Internet Services SYSTEM and WEBGUI.
Publish these services with the Context
Menu -> Publish -> Complete Service
4- Browse to http://<server>:<icmport>/sap/bc/gui/
sap/its/webgui/! and login to the
webgui.
Hope this will help.
Please reward suitable points.

Getting the call stack up to a certain location.

Dear friends,
I am searching for a function or method that can give me
the call stack(like in debug mode).
If you know of a function that provides this information
please let me know, its very urgent.
Thanks in advance,
Eitan Illuz.

Hello Eli
You may have a look at thread:

RangeError: Maximum call stack size exceeded

Dear all,
we are executing and EDGE project in a Samsung SmartTV. In more powerful models (more memory and cpu) the execution is correct. but in some old TV models we receive the following message:
File: file://c/........../EDGE_006/edge_includes/edge.2.0.1.min.js
Line No: 135
Error Detail: RangeError: Maximum call stack size exceeded.
It seems that this happens depending on the complexity of the EDGE project, as for some simple projects it works.
we would like to adjust our EDGE project for this less powerful models modifiying animations and simplifying complexity, but we dont know where to start (which animations to remove, etc.)
Or if there are some parameters in the edge API to adjust in order to increase performance in low memory browsers.
Thank you in advance,
Luis

Unless you know this DLL is using exceedingly lots of stack (at least
several dozens of MB) for whatever obscure reasons it is very unlikely
that running out of stack space is causing your problem. More likely
either the DLL does something nasty to a data pointer passed in to it or
you made an error in setting up the call to the DLL.
For instace if the DLL expects strings or array pointers to be passed in
they need to
be allocated by the caller (here LabVIEW) and you need to
tell LabVIEW to do that in the diagram code.

Interpreting a call stack traceback

I am trying to diagnose a segv crash in our application but All I have to go on is a call stack traceback that was harvested at the time of the crash. This is workshop 4.0 vintage running on Solaris 2.6. The application was built with level 2 optimisation.
one line of the traceback follows:
00098de8 CSax_ExchApi::WriteData(CEis_OutMsgContext*)(88f1e4, 539878, 894750, 3a5e8c, 1, 5ae118) + 114
My questions are:
1. What does the + 114 signify?
2. Is it correct that the 1st arg shown (88f1e4) is the value of the this ptr?
3. Is it correct that the 2nd arg shown (539878) is the value of the parameter?
4. Do the values of the rest of the args have any significance?
Thanks

one line of the traceback follows:
00098de8
CSax_ExchApi::WriteData(CEis_OutMsgContext*)(88f1e4,
539878, 894750, 3a5e8c, 1, 5ae118) + 114
My questions are:
1. What does the + 114 signify?The program counter was 114 bytes past the beginning of the named function. The traceback looks for the nearest defined symbol before the location. If the problem is in a non-global function, the address might not be inside the named function. Example:
int foo(){ return 0; } // global tiny function
static int bar() // non-global function
// crash in here someplace
The traceback will show a reference to foo + some offset, because bar is not a known symbol.
Now, the odd thing here is that on SPARC, instructions are on 4-byte boundaries, and 114 is not a multiple of 4. The problem might be a jump to a non-aligned address, which will cause a fault and crash. An invalid jump is normally the result of using a bad pointer. The use of the bad pointer could be far-removed from when and where the crash occurred.
2. Is it correct that the 1st arg shown (88f1e4) is
the value of the this ptr?Yes.
3. Is it correct that the 2nd arg shown (539878) is the value of the parameter?Yes, if the parameter size is 32 bits.
4. Do the values of the rest of the args have any significance?Without debug data, the traceback arbitrarily shows the first few values on the stack, but cannot interpret them. You need to compare the values shown to the actual source code to make sense out of them.

API for call stack traceback?

I don't mean to diss the use of debuggers like dbx, but there are times when other tools would suit a problem better.
Is there a routine I can call from a C++ program to print a current call stack traceback in the current thread?

Is there way how to get debug information from program compiled with -g? I mean source file and line. I use printstack, but source file and line could be more comfotable :).

F60WEBMX PROCESSES 의 UNIX CALL STACK 생성방법

F60WEBMX PROCESSES 의 UNIX CALL STACK 생성방법
==========================================
PURPOSE
F60webmx process 가 CPU을 많이 차지하는 경우가 간혹 있으며
SQL trace외에 UNIX call stack으로 위 Process가 현재 Active 상태인지
혹은 Dump 등을 분석시 UNIX trace를 생성하는 방법니다.
Explanation
먼저 아래 명령어와 같이 Trace 를 실행합니다.
Log on as root.
# trace -a -L 4000000 -T 2000000 o ./trace.out;
# owsctl start admin
# trcstop
# trcrpt -O exec=on,pid=on trace.out > trcrpt.1
그다음 아래단계처럼 해당 Process를 찾습니다.
1) PS 명령어로 Process를 찾습니다.
          - ps -ef | grep -i f60webmx | grep webfile
     This will return an output like this:
          applmgr 6324 1052 0 14:34:56 ? 0:01 f60webmx webfile=5,1,gjimenez-sun     _14007_PROD
2) TUSC 를 실행합니다.
Execute your TUSC command for your process id identified on the previous step. In the above example, the PID is 6324.
3) 문제를 Reproduce하면서 Webfile 1번과 2번을 유의하여 Monitoring 합니다.
Ask any of your users in the location where you are having problems to log in to the application (Forms). Then,
make sure that a new process has been spawn (in the above example, a new f60webmx process should be spawn with a the parameter
webfile increased by 1: f60webmx webfile=5,2). This will tell us that the process #1 has been taken by the user we expect.
4) 문제가 재현될때까지 기다립니다.
Wait until the error reproduces for this user. Once the error surfaces, the TUSC process will die all by itself. Make sure you
upload the output file through Metalink for further examination.
Reference Documents
Note 244072.1

Always paste only the ERROR lines, not the full content.
Suggestions: Upgrade your Database for 9i to 10g (9i is out of support)
                      Size your hardware and application based on your system load etc
Solution for above issue: Try to kill some of the work processes from OS level (Application restart is better than this)

Call stack depth

Hello,
i would like to know if there is any possibility in PL/SQL to get the current stack depth inoformation. I am not sure if this is the right description, i would like to know how deep into calling subprograms has a program execution come at the moment.
I would like to use this information for automatical indentation of log file, produced by a pl/sql procedure call.

Call stack

What is the best way to see call stack in JSP/servlet application?
How can I see in which order classes and methods are called when I for example clik the button on web page?
"The call stack is a list of classes and methods that have been called or
executed in java application. The most current method is at
the top of the stack. The element second from the top issued a call to
execute the top-most method, and so on and so forth."

I use Struts and JSTL.
I would like to see how it works.
All call stack from beginning (http request) to the end (jsp output).
So, where to put this System.out?
At the end in my jsp?
In front/dispatch servlet?
Where?
How many thread was created if I have tags in jsp?
How to output all of them?
Again, I have ONE jsp page with tags and I would like to see call stack i.e. which classes and methods was called when I call this jsp - http request?

Get the parameter values and entire call stack in procedure

Does Oracle provides any utility procedure like format_error_stack, and format_call_stack, where I can get entire procedure/function call along with parameters passed to it so that I can just dump that into some table as part of logging.
-S

Thanks for the response. I guess who_am_i and who_called_me gives only the proc/function name. I am looking for a way to figure out what was the parameters and values passed to the procedure so I can simply dump them into my log tables.
This would be similar to any java application where it can dump its own call stack, which has parameters and values passed to it and can dump into a log file.
For ex:
create or replace procedure my_proc( a number, b varchar2)
is
begin
--this log stack should be able to print procedure name and parameters passed to it.
-- I should be able to use log_stack without any parameters in any procedure/function
log_stack();
end;
--My output should be something like this
SQL> EXEC my_proc(1, 'ABC')
CALL STACK:
my_proc(a => 1, b => 'ABC')

TelemetryClient.TrackException Does Not Include Method Name Or Call Stack (Windows Store App)

We are attempting to use Application Insights (v0.12.0-build17386) for our Windows Store App. When we use TelemetryClient.TrackException, no details appear in the azure portal. The Failed Method is "Could Not Parse" and the Call Stack
is empty. If we click on the "..." it gives more details but still no method name or call stack information to help us determine where the exception was thrown. Is this by design, not implemented, or did we miss something obvious? The
code is very simple:
public static void LogException(Exception exception)
TelemetryClient telemetryClient = new TelemetryClient();
telemetryClient.TrackException(exception);

This is a known limitation of this version. It is in the backlog to fix. Note though that 0.13 is out already and fix should be included in the next version (0.14)

After I restart my phone, all apps are disappear including setting, contacts, and call icon and etc. can someone help me? The phone now only remain two apps. I try to search using the phone serch engine but when i click on the result, there is a message pop out as: Unsupported URL

Swipe back (right to left) to the home screens that contain the rest of your apps.
Failing that, reset the phone: hold down Sleep and Home buttons until the Apple logo is displayed. No data is lost.

Reading from ABAP memory, not available in call stack

Hi,
I need to read a table from ABAP memory. It is not available from the call stack, so I cant use the standard assign approach. The internal table is listed under System areas -> Area ITABS-HEADS with the name \FUNCTION-POOL=MLSP\DATA=IY_ESLL[]
Is it even possible to read this table? Seems as though I have to access function-pool MLSP to find it.
Regards,
Damian

Hi,
The main program of this function pool is SAPLMLSP. If you in any of theses includes can add a small form that returns the content of internal table ( IY_ESLL[] ) that should solve your problem.
In the program that need the data, write something like :
PERFORM Z_GET_MLSP_DATA(SAPLMLSP) using GT_ESLL.
This form can be created within any sub-include within the SAPLMLSP.
However, with a quick look at SAPLMLSP does not reveal any user modifiable includes, but I didn't check very carefully.
If you are on ECC 6.0, there are plenty of enhancement spots, which could be used for this purpose.
