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.

Verify Error 1030# Stack Depth unbalanced 1 != 0.

Hi,
Iam trying to inject some code into the SWF File using an
opensource Java Framework. My code is getting injected correctly. I
saw this, when i tried to decompile the SWF file into which i
injected the code. But there is something that needs to be handled
when it comes to handling the instruction sets available inside the
method where i injected the code. I just wanted to know what that 1
and 0 points to, in the below given error message.
Verify Error 1030# Stack Depth unbalanced 1 != 0.
If somebody can help me out in making me understand the 1 and
0 in the error message, i can further proceed to correct the
mistake that i have done.
Thanks,

Hi All,
I am able to find the root cause for this. For AS 3 classes,
while parsing the ABC code, every method body will be a set of
instructions in which each instruction will have an offset to it.
This offset will be useful to mark the target for branching
instructions like if, while etc.... Because, these instructions
contains targetoffset as a parameter to which the instruction has
to jump when the condition becomes true or false. The process what
i am doing is i do some code injection to replace the URLRequest
calls. The flash file in which i got this error, i did replace the
URLRequest call to my own method call and this code was being
wrapped up by an IF block. Because of the code injection, i need to
update the offset of the instructions with the difference offset
value. I did this, but i missed the jumpoffset parameter of the if
block wrapping my injected code which was the root cause. I did fix
this...
Thanks,
Prabakaran Srinivasan.

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.
Transaction Canceled ITS_P 001 ( )
Message Id: ITS_P
Message No: 001
I just checked these threads but did not help much,

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.

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)

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.

Getting the call stack up to a certain location.

Dear friends,

Thanks in advance,

Subr stack depth exceeded

Hello,
makeotflib [WARNING] subr stack depth exceeded (reduced)
Is this a problem of my feature code or more an information statment of
MakeOTF?
Anything to do?
Andreas

This is not a problem to worry about. It means that when MakeOTF tried to subroutinizedthis font in order to make it smaller, the font was so difficult that MakeOTFran out of the fixed reiteration depth, and as a result the analysis was not as complete as might have been possible. The result is that your font is fine, but may not be compressed to the theoretical maximum.

Runtime Stack Depth

I am writing some more "exotic" datastructures (AVL trees, Red-Black Trees). My main concern is the runtime stack depth. I don't want blow over it if i am inserting a large amount of data. Would the best approach be to write it procedurally instead of recursively?

Both AVL and Red-Black trees are balanced binary trees, so the maximum depth of the tree is 2 lg n, where n is the number of elements and lg is the logarithm base 2. To have a tree depth of 64, you'd need over 4 billion elements in your tree. For this to overflow even a 64 KB stack, you'd need to store 1 KB of local variables, or 256 ints, in your recursive method. The default stack depth is much bigger, usually 512 KB or 1 MB.
I wouldn't consider stack overflow in deciding whether to use recursion or iteration.

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.
Regards,
Puneet Jhari.

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.
