JConsole Heap and Non Heap Objects viewing
Hi,
I am looking for a good tutorial on how to view what are the objects (specially their toString() value) which exists in different heap (eden, survivor,tenure ) and non heap spaces (permgen (ro,rw), code cache) ).
Are there any good tutorials out there to view these objects live..
I am assuming there jconsole in support with other jdk tools these details could be seen.

Cumulative and Non-cumulative KFs
Guys,
so I am confused about cumulative/Non-cumulative keyfigures. I read what it says about them on help.sap.com
Flow/non-cumulative value
You can select the key figure as a cumulative value. Values for this key figure have to be posted in each time unit, for which values for this key figure are to be reported.
Non-cumulative with non-cumulative change
The key figure is a non-cumulative. You have to enter a key figure that represents the non-cumulative change of the non-cumulative value. There do not have to be values for this key figure in every time unit. For the non-cumulative key figure, values are only stored for selected times (markers). The values for the remaining times are calculated from the value in a marker and the intermediary non-cumulative changes.
Non-Cumulative with inflow and outflow
The key figure is a non-cumulative. You have to specify two key figures that represent the inflow and outflow of a non-cumulative value.
For non-cumulatives with non-cumulative change, or inflow and outflow, the two key figures themselves are not allowed to be non-cumulative values, but must represent cumulative values. They must be the same type (for example, amount, and quantity) as the non-cumulative value."
and also checked a few threads on sdn but still a little confused about their purpose.
Can someone tell me when do we use which one?
Thanks,
RG.Hi Ram,
Cummulative & Non Cummulative Key Figures :
Basically the key figures are of two types cumulative and non cumulative.
Cumulative are the normal one which you use always and they always bring the new values of the key figures in the delta that is if suppose A has value 10 and after change the new value is 20 then you will use cumulative key figures there, and your delta( new value) will bring 20.
but suppose your key figures field only the change in the prior value that is in this case the delta in the key figure value will bring 10 (20-10- change of 10 )as new value in the key figure A then you will have to model it through the non cumulaitve key figures.
Now
1) Cumulative is for the first case that is if the key figure alwyas brings the new values of the key figure and not the change sin the key fiures value.
2)NCum. value with NCUM value change:
In this case ther is only one field which brings the changes for a particualr key figure and you ahve to define that key figure as non cumulative.
Ex: In case of stock only one filed brings both ingoing value and outgoing value so 10 ,-4,100,-34.....
In this case you will this option and use the key figure here in the space provided.
3) In this case you haev two separate key figures one for the inflow of stocks and one for the outflow of the stocks.
you use one key figure for the inflow and one key figure for the outflow.
The main key figure autiomatically takes care of the logic and gives the correct output upon the summation
net value of stocks( inflow- outflow).
Also do remember in this case the key figure for inflow and out flow are the basic key figures that is cumulative key figures.
A non-cumulative is a non-aggregating key figure on the level of one or more objects that is always displayed in relation to time. Examples of non-cumulatives include headcount, account balance and material inventory. here the aggregation of key figure is based on the another info object
There are two different ways to define non-cumulative key figures:
u2022 Non-cumulative key figure with non-cumulative changes:
Before you can define the non-cumulative key figure, an additional cumulative key figure containing the non-cumulative change must exist as an InfoObject.
u2022 Non-cumulative key figure with inflows and outflows
There has to be two additional cumulative key figures as InfoObjects for non-cumulative key figures - one for inflows and one for outflows. The cumulative key figures have to have the same technical properties as the non-cumulative key figure, and the aggregation and exception aggregation have to be SUM.
Features of non-cummulative key figures
A non-aggregating key Figure.
Records are not summarized for Reporting
Exception Aggregation is being applied on these key figures on the level of one or more info objects usually with time .
Examples: Head Count, Account balance, Material stock
consider simple senario
Date Net Stock Quantity Sales Revenue
01.02.2005 40 1000
02.02.2005 50 2000
03.02.2005 25 3000
this is the query output if stock quantity has treated as cummulative and non-cummulative key figures
if stock quantity taken as a cummulative key figure
Date NET STOCK QUANTITY SALES REVENUE
01.02.2005 30 1000
02.02.2005 50 2000
03.02.2005 20 3000
RESULT 100 6000
in the above result the key figure has aggregated to the total value that wont give sense to the net stock quantity
if stock quantity taken as non-cummulative key figure
Date Net Stock Quantity (LAST) Sales Revenue
01.02.2005 30 1000
02.02.2005 50 2000
03.02.2005 20 3000

Hope it helps you.

Example program for returninng and importing with value addition
HI ,
I want few example programs on how to use the abap oops with returning addition and importing with value addition as Im getting syntax error for the Program when Im declaring them with these additions
Thnaks .Hello,
This statement declares a general instance method meth. Use additions ABSTRACT and FINAL to make the method abstract or final.
The additions IMPORTING, EXPORTING and CHANGING define the parameter interface of the method. After every addition, the corresponding formal parameters are defined by a specification of the list parameters.
The other additions determine which exceptions the method can propagate or trigger and determine whether the method is abstract or final.
Note
Within a method, you can use the logical expression IS SUPPLIED to check whether an actual parameter was assigned to an optional formal parameter at the call.
Addition 1
... IMPORTING parameters PREFERRED PARAMETER p
Effect
IMPORTING defines input parameters. When calling the method, you need not specify an appropriate actual parameter for every non-optional input parameter. During the call, the content of the actual parameter is passed to the input parameter. The content of the input parameter - for which the reference transfer is defined - cannot be changed in the method.
Use PREFERRED PARAMETER to identify an input parameter p1 p2 ... of list parameters after IMPORTING as a preferred parameter. This specification makes sense only if all input parameters are optional. When calling the method with the syntax
CALL METHOD meth( a ).
the actual parameter a is assigned to the preferred parameter if you have appropriate use of a functional method at an operand position.
Addition 2
... EXPORTING parameters
Effect
EXPORTING defines output parameters. When calling the method, you can specify an appropriate actual parameter for every output parameter. The content of the output parameter - which is defined for value transfer - is passed to the actual parameter at the call after the method has been completed successfully.
Note
An output parameter that is defined for the reference transfer is not initialized when the method is called. Therefore, no read access to it should take place before the first write access.
Addition 3
... CHANGING parameters
Effect
CHANGING defines input/output parameters. When calling the method, you must specify an appropriate actual parameter for every non-optional input/output parameter. The content of the actual parameter is passed to the input/output parameter at the call, and after the method has been completed, the content of the input/output parameter is passed to the actual parameter.
Example
The method read_spfli_into_table of this example has an input and an output parameter, which are typed fully by reference to the ABAP Dictionary.
CLASS flights DEFINITION.
PUBLIC SECTION.
METHODS read_spfli_into_table
IMPORTING VALUE(id) TYPE spfli-carrid
EXPORTING flight_tab TYPE spfli_tab.
ENDCLASS.
Addition 4
... RAISING exc1 exc2 ...
Effect
Use addition RAISING to declare the class-based exceptions exc1 exc2 ... that can be propagated from the method to the caller.
For exc1 exc2 ..., you can specify all exception classes that are visible at this position and are subclasses of CX_STATIC_CHECK or CX_DYNAMIC_CHECK. You must specify the exception classes in ascending order corresponding to their inheritance hierarchy.
Exceptions of the categories CX_STATIC_CHECK and CX_DYNAMIC_CHECK must be declared explicitly, otherwise a propagation results in a violation of the interface. An interface violation results in a treatable exception CX_SY_NO_HANDLER. Exceptions of category CX_NO_CHECK are always implicitly declared.
Notes
The declaration of exceptions of category CX_STATIC_CHECK is checked statically at the syntax check. For exceptions of category CX_DYNAMIC_CHECK, the check is executed at runtime.
In a method in which class-based exceptions are declared with the addition RAISING, you cannot use the statement CATCH SYSTEM-EXCEPTIONS. Instead, handle the relevant treatable exceptions in a TRY control structure.
Example
In class math, you can propagate all exceptions represented by class CX_SY_ARITHMETIC_ERROR and its subclasses from within method divide_1_by. If, for example, the input parameter operand is filled at the call with the value 0, then the exception CX_SY_ZERODIVIDE is triggered, propagated, and can, as shown in the example, be handled by the caller in a TRY control structure.
CLASS math DEFINITION.
PUBLIC SECTION.
METHODS divide_1_by
IMPORTING operand TYPE I
EXPORTING result TYPE f
RAISING cx_sy_arithmetic_error.
ENDCLASS.
CLASS math IMPLEMENTATION.
METHOD divide_1_by.
result = 1 / operand.
ENDMETHOD.
ENDCLASS.
START-OF-SELECTION.
DATA oref TYPE REF TO math.
DATA exc TYPE REF TO cx_sy_arithmetic_error.
DATA res TYPE f.
DATA text TYPE string.
CREATE OBJECT oref.
TRY.
oref->divide_1_by( EXPORTING operand = 4
IMPORTING result = res ).
text = res.
CATCH cx_sy_arithmetic_error INTO exc.
text = exc->get_text( ).
ENDTRY.
MESSAGE text TYPE 'I'.
Addition 5
... EXCEPTIONS exc1 exc2 ...
Effect
Use addition EXCEPTIONS to define a list of non-class-based exceptions exc1 exc2..., which can be triggered with the statements RAISE or MESSAGE RAISING in the method. You specify identifiers exc1 exc2 ... for the exceptions to be defined at will and directly. Exceptions defined in this way are bound to the method - similar to formal parameters - and cannot be propagated.
If such an exception is triggered in a method and no return value has been assigned to it in the addition EXCEPTIONS of the CALL METHOD statement in the method call, then a runtime error occurs.
Note
The additions RAISING and EXCEPTIONS cannot be used simultaneously. For new developments starting at release 6.10, we recommend to use class-based exceptions, which are independent of the respective method.
Example
In the class math, for method divide_1_by an exception arith_error is defined, which is triggered in the method with the RAISE statement if an arithmetic error occurs. If, for example, the input parameter operand is filled with value 0 at the call, the exception arith_error is triggered in the method-internal handling of exception CX_SY_ZERODIVIDE and handled after the call of the method by evaluating sy-subrc.
CLASS math DEFINITION.
PUBLIC SECTION.
METHODS divide_1_by
IMPORTING operand TYPE I
EXPORTING result TYPE f
EXCEPTIONS arith_error.
ENDCLASS.
CLASS math IMPLEMENTATION.
METHOD divide_1_by.
TRY.
result = 1 / operand.
CATCH cx_sy_arithmetic_error.
RAISE arith_error.
ENDTRY.
ENDMETHOD.
ENDCLASS.
START-OF-SELECTION.
DATA res TYPE f.
DATA oref TYPE REF TO math.
CREATE OBJECT oref.
oref->divide_1_by( EXPORTING operand = 4
IMPORTING result = res
EXCEPTIONS arith_error = 4 ).
IF sy-subrc = 0.
WRITE res.
ELSE.
WRITE 'Arithmetic error!'.
ENDIF.

there seems to be something wrong with your network configuration (either on server, or in the vm configuration).
Pls. also next time update what version you are using. Based on the path to the repository I believe it is 3.0.X
Easiest will probably be to simply use the manager and edit the network setting of the VM (network device/bridge) there.
If error continues to exists, please post your network setup of the server (ifcfongi -a and brctl show) and post the vm.cfg

Static and non-static variables and methods
Hi all,
There's an excellent thread that outlines very clearly the differences between static and non-static:
http://forum.java.sun.com/thread.jsp?forum=54&thread=374018
But I have to admit, that it still hasn't helped me solve my problem. There's obviously something I haven't yet grasped and if anyone could make it clear to me I would be most grateful.
Bascially, I've got a servlet that instatiates a message system (ie starts it running), or, according to the action passed to it from the form, stops the message system, queries its status (ie finds out if its actually running or not) and, from time to time, writes the message system's progress to the browser.
My skeleton code then looks like this:
public class IMS extends HttpServlet
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
doPost(request, response);
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
//get the various parameters...
if (user.equalsIgnoreCase(username) && pass.equalsIgnoreCase(password))
if(action.equalsIgnoreCase("start"))
try
IMSRequest imsRequest = new IMSRequest();
imsRequest.startIMS(response);
catch(IOException ex)
catch(ClassNotFoundException ex)
else if(action.equalsIgnoreCase("stop"))
try
StopIMS stopIMS = new StopIMS();
stopIMS.stop(response);
catch(IOException ex)
else if(action.equalsIgnoreCase("status"))
try
ViewStatus status = new ViewStatus();
status.view(response);
catch(IOException ex)
else
response.sendRedirect ("/IMS/wrongPassword.html");
public class IMSRequest
//a whole load of other variables
public PrintWriter out;
public int messageNumber;
public int n;
public boolean status = false; //surely this is a static variable?
public String messageData = ""; // and perhaps this too?
public IMSRequest()
public void startIMS(HttpServletResponse response) throws IOException, ClassNotFoundException
try
response.setContentType("text/html");
out = response.getWriter();
for(n = 1 ; ; n++ )
getMessageInstance();
File file = new File("/Users/damian/Desktop/Test/stop_IMS");
if (n == 1 && file.exists())
file.delete();
else if (file.exists())
throw new ServletException();
try
databaseConnect();
catch (ClassNotFoundException e)
//here I start to get compile problems, saying I can't access non-static methods from inside a static method
out.println(FrontPage.displayHeader());
out.println("</BODY>\n</HTML>");
out.close();
Thread.sleep(1000);
catch (Exception e)
}OK, so, specifially, my problem is this:
Do I assume that when I instantiate the object imsRequest thus;
IMSRequest imsRequest = new IMSRequest();
imsRequest.startIMS(response); I am no longer in a static method? That's what I thought. But the problem is that, in the class, IMSRequest I start to get compile problems saying that I can't access non-static variables from a static method, and so on and so on.
I know I can cheat by changing these to static variables, but there are some specific variables that just shouldn't be static. It seems that something has escaped me. Can anyone point out what it is?
Many thanks for your time and I will gladly post more code/explain my problem in more detail, if it helps you to explain it to me.
DamianCan I just ask you one more question though?Okay, but I warn you: it's 1:00 a.m., I've been doing almost nothing but Java for about 18 hours, and I don't do servlets, so don't take any of this as gospel.
If, however, from another class (FrontPage for
example), I call ((new.IMSRequest().writeHTML) or
something like that, then I'm creating a new instance
of IMSRequest (right?)That's what new does, yes.
and therefore I am never going
to see the information I need from my original
IMSRequest instance. Am I right on this?I don't know. That's up to you. What do you do with the existing IMS request when you create the new FrontPage? Is there another reference to it somewhere? I don't know enough about your design or the goal of your software to really answer.
On the other hand, IMSRequest is designed to run
continuously (prehaps for hours), so I don't really
want to just print out a continuous stream of stuff to
the browser. How can I though, every so often, call
the status of this instance of this servlet?One possibility is to pass the existing IMSRequest to the FrontPage and have it use that one, rather than creating its own. Or is that not what you're asking? Again, I don't have enough details (or maybe just not enough functioning brain cells) to see how it all fits together.
One thing that puzzles me here: It seems to me that FP uses IMSReq, but IMSReq also uses FP. Is that the case? Those two way dependencies can make things ugly in a hurry, and are often a sign of bad design. It may be perfectly valid for what you're doing, but you may want to look at it closely and see if there's a better way. -
Difference between cumulative and non-cumulative key figures
Hi,
What is the difference between cumulative and non-cumulative key figures and under what conditions they are used. What is snapshort and where it is used.Hi.............

Authoritative restore and Non Authoritative restore
Hi
1.Whats the difference between Authoritative restore and Non Authoritative restore?Please explain with the example.
Also If any one have the Windows question and answers with the troubleshooting and live scenarios please help meHello,
Performing an Authoritative Restore of Active Directory Objects: http://technet.microsoft.com/en-us/library/cc779573(WS.10).aspx
Exemple: You accidentally deleted an AD user and you want to restore it. You can use an authoritative restore to perform that.
Note that now you can do that by enabling AD recycle Bin and you don't still need a restore operation.
Performing a Nonauthoritative Restore of a Domain Controller: http://technet.microsoft.com/en-us/library/cc784922(WS.10).aspx
Example: You had hardware problems on a DC and you solved them after re-installing the DC OS. You can use a non-authoritative restore so that you don't delete recently made changes.

I have got a Activation Lock on my iPhone and I need to get it activated. I don't know what Apple ID I was using with my iPhone. It shows as U***@h******.uk which is too short to be my email address. I have reset all my Apple ID passwords and none are activating my iPhone. I have also been into the apple store and they have tried to find out the Apple ID my iPhone was using but this was not successful. The serial number of my iPhone is: C32JN641DTWF
You are going to need to change the email address you use with your old ID. Once you have got access to your old account you will then log into both accounts at the same time on your Mac and transfer your data to a single account. We can do this later, but need you to get access to your old account first.

I Dislike the Terms "Destructive" and "Non-Destructive" Editing
Some folks in the Photoshop realm use the terms "destructive" and "non-destructive" to describe ways of using Photoshop in which transforms are applied directly to pixel values vs. being applied via layers or smart filters or smart objects or other means.
Do you realize that the term "destructive" is actually mildly offensive to those who know what they're doing and choose to alter their pixel values on purpose?
I understand that teaching new people to use Photoshop in a way that doesn't "destroy" their original image data is generally a good thing, and I'm willing to overlook the use of the term as long as you don't confront me and tell me what I'm doing when I choose to alter pixel values is "wrong" (or when I choose to advise others on doing so).
For that people who claim editing pixel values is "destructive", I offer this one response, which is generally valuable advice, in return:
Never overwrite your original file.
There. The "destruction" has ceased utterly.
It's common sense, really. You might want to use that file for something else in the future.
If you shoot in raw mode with a digital camera, then you actually can't overwrite your raw files. That's a handy side effect, though some don't use raw mode or even start working with digital photographs.
In any case, when you open your image consider getting in the habit of immediately doing File - Save As and creating a .psd or .tif elsewhere, so that you can subsequently do File - Save to save your intermediate results.
There can actually be many advantages to altering pixel values, if you know what you're doing and choose to do so. But sometimes even the most adept Photoshop user might find that a given step created a monster; that's okay, there's a multi-step History palette for going back. I normally set mine to keep a deep history, to give me a safety net if I DO do something wrong, though I tend to use it rarely.
And for those who would tout the disadvantages to editing "destructively", there can be huge disadvantages to doing it "non-destructively" as well... Accumulating a large number of layers slows things down and can use a lot of RAM... With downsized zooms the mixing can yield posterization that isn't really there, or gee whiz, just TRY finding a computer fast enough to use smart filters in a meaningful way. Just the concept of layers, if one hasn't worked out how layer data is combined in one's own mind, can be daunting to a new person!
So I ask that you please stop saying that the "only" or "best" way to use Photoshop is to edit "non-destructively". There are folks who feel that is offensive and arrogant. I think the one thing everyone can agree upon is that THERE IS NO ONE OR BEST WAY TO USE PHOTOSHOP!
You go ahead and do your editing your way. I prefer to do "constructive" editing.
Thanks for listening to my rant.

When you alter image data in a manner that cannot be reverted, you have destroyed it.
Really?
That's one of those things that one is not supposed to question. It just sounds so right!
Problem is, it's insufficient in and of itself, and misleading... It's a rule of thumb that's way too general.
What IS "data" anyway? Arrangement of magnetic spots on a disk? My disk is still whole, so we're not talking about physical destruction here.
One could argue that all the data is all still there in many cases of pixel-value-change editing (e.g., where there has been no resizing). The image file is the same size! Same amount of data.
Upsampling, or making a copy of an image is actually creating more data, not destroying data. Thus there is no general "destruction", but the terms "construction" or "creation" could be used.
But wait, perhaps you're really talking about destroying information, not data... Well...
As it turns out the term "destructive" is still off base. I have altered the information, possibly even adding important information. If I make a copy this is a no brainer. Even if I don't, depending on a person's skill in editing, the altered result could still carry all the original information that was important plus information added by editing, and be quite possibly better for its intended purpose (human consumption) than the image before the edit. That's the goal!
So now we're talking about important information vs. unimportant information. And of course we're talking about fitness for a future purpose.
As with anything, there are multiple ways to get there and multiple ways to interpret the words.
The term "destructive" in my opinion was invented to further someone's agenda.

Examples for SAP Memory and ABAP Memory
Hi all,
can u give me one example of sap memory and abap memory.
RanjithHi,
<b>SAP Memory</b>
SAP memory is a memory area to which all main sessions within a SAPgui have access. You can use SAP memory either to pass data from one program to another within a session, or to pass data from one session to another. Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters). These parameters can be set either for a particular user or for a particular program at the time of logon using the SET PARAMETER statement. Other ABAP programs can then retrieve the set parameters using the GET PARAMETER statement. The most frequent use of SPA/GPA parameters is to fill input fields on screens .
<b>example:</b>
ABAP programs can access the parameters using the SET PARAMETER and GET PARAMETERstatements.
To fill one, use:
SET PARAMETER ID pid FIELD f
This statement saves the contents of field f under the ID pid in the SAP memory. The ID pid can be up to 20 characters long. If there was already a value stored under pid, this statement overwrites it. If you double-click pid in the ABAP Editor, parameters that do not exist can be created as a Repository object.
To read an SPA/GPA parameter, use:
GET PARAMETER ID pid FIELD f.
This statement places the value stored under the pid ID into the variable f. If the system does not find any value for pid in the SAP memory, sy-subrc is set to 4. Otherwise, it sets the value to 0.
<b>ABAP Memory</b>
ABAP memory is a memory area that all ABAP programs within the same internal session can access using the EXPORT and IMPORT statements. Data within this memory area remains throughout a sequence of program calls, with the exception of LEAVE TO TRANSACTION. To pass data to a program that you are calling, the data needs to be placed in ABAP memory before the call is made from the internal calling session using the EXPORT statement. The internal session of the called program then replaces that of the calling program. The program called can then read from the ABAP memory using the IMPORT statement. If control is then returned to the program that made the initial call, the same procedure operates in reverse.If a transaction is called using LEAVE TO TRANSACTION, the ABAP memory and the call stack are deleted. They cannot be used for data transfer.
Since objects belonging to ABAP objects can only be accessed within an internal session, it does not make sense and is therefore forbidden (from a syntax point of view) to pass a reference to an object to a calling program through the ABAP memory.
<b>Example:</b>
Export hello to memory id 'Hello_world'.
Import hello from memory id 'Hello_world'

Oracle reserved and non-reserved keywords
Hello,
I'm looking for a list of reserved and non-reserved keywords for all Oracle versions starting from 9.
I think Oracle starts at R1, right? So the versions needed would be:
9.1, 9.2
10.1, 10.2 and
11.1
I found lists of keywords querying Oracle view V$RESERVED_WORDS
http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14237/dynviews_2048.htm#REFRN30204
here:
http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14200/ap_keywd.htm
However, this is only for version 10.2 and it contains only reserved keywords.
I need a list for every maintenance/minor version. This list must contain all keywords in Oracle PL/SQL, not just the reserved ones, but also those which shouldn't be used in certain contexts described by the V$RESERVED_WORDS view (former link) -> probably reserved = 'N'.
Since I don't own a copy of Oracle and definitely not of every minor version, does anyone know where to obtain such lists?
You might want to do me a favor and query that view for me... ;-) (you can send the output to "k w u t z k e AT w e b DOT d e" ... don't forget to mention the version)
From what the view tells me, the SQL statements to query are:
For reserved words:
select keyword from v$reserved_words where reserved='Y' order by keyword;
For all other non-reserved words:
select keyword from v$reserved_words where reserved='N' order by keyword;
Are there any keywords/entities that are neither reserved='Y' nor reserved='N'?
Can anyone help on this issue please?
TIA,
KarstenNot sure about differences between specific versions but the easy way to get reserved words is in SQL*Plus...
