Report RFKABLOO i want to know how the layout works

Hi all,
in report RFKABLOO i want to know how the layout works.
like it has a parameter layout in which if we select 5 fields
it shows 5 in print screen output.
what is the process and how it works in this report?

Why not you use the Debugging option?
Do not expect others to work for you.
Also do not post a thread more than once in the forum.
Read the [Forum Rules|http://wiki.sdn.sap.com/wiki/x/FgQ] before posting more.

How do I learn how the sidebar works in Mail?

I have added 5 accounts but I can't make sense of why certain things are in certain areas. For example, what's the difference between Mailboxes and On My Mac? I was excited to move towards managing all my email in one place.
I have numerous questions and rather than write them all down here, I'd just like to know where I can learn more. Even just know which OS X version added this particular sidebar might help.
I have spent about 2 hours searching Apple.com, Lynda.com, YouTube and other sources to find a tutorial to describe the details of the sidebar, but I can't find anything useful. Everything is for newbies and I'm actually an advanced email user -- except that I'm confused as to how the sidebar works.
Suggestions, please. Thank you!
In gratitude,
Karyn

How the balance works for http/https in CSS?

I want to understand how the balance works for http/https in the CSS.
As per doc,
- http/1.0=single URL per TCP connection
- http/1.1=persistent connection.
Q1. my understanding is http is stateless connection so needs TCP session for each URL. how the http/1.1 works with persistent. keep the same TCP session for a multiple URL request?
Q2. https is using single URL and continue processing until terminate the https instead of open another URL in the middle of transaction. in this case, I think the client can stick into same service based on the assumption the CSS support persistent. if then, no advanced sticky(ex, srcip) required?
Q3. looks below both are analogy. what's difference between them?
- balance srcip(same src IP to the same service)
- advanced-balance sticky-srcip
Q4. what's balance decision mechanism for "balance roundrobin" to distribute evenly? ex, in case of multiple URL request coming from same client. evenly distribute URLs?
Regards,

Hello,
first let me clarify 1 point.
HTTP/HTTPS are standards that are defined in RFC.
For HTTP/1.1 you can check the following RFC
http://www.faqs.org/rfcs/rfc2616.html
Therefore, the behavior of HTTP 1.1 is not defined by the CSS.
Q1- HTTP/1.1 simply keeps 1 TCP connection to send a received mutiplie HTTP request/response.
HTTP/1.0 will open 1 TCP connection for every HTTP request.
Q2- HTTPS is just HTTP over SSL.
So basically the same rule as above applies.
HTTP/1.1 can use 1 SSL connection for many HTTP request/response while HTTP/1.0 will use 1 SSL connection for each HTTP request.
Therefore, if you have customer using HTTP/1.0 you need some form of stickyness to guarantee that every connections will go to the same server.
Even if only using HTTP/1.1 you may need stickyness.
A user could disconnect and reconnect and require to be loadbalanced to the same server as before.
Q3- There is a big different between balance srcip and sticky-srcip.
The balance srcip simply hash the source ip address to find the destination server.
The problem of this method is that the loadbalancing is not guarantee to be evenly distributed between the servers.
With sticky-srcip, you use a normal balance method like round-robin, and then you create a sticky entry in a sticky table.
Next time this user comes back we first check the sticky entry to find the destination server.
The advantage is that it guarantess your users will be evenly distributed among the server.
Q4- roundrobin is applied to connection - not url [by default].
So if you have 2 users and they both open 1 connection, the CSS will send 1 connection to 2 different servers.
So each server has 1 connection.
If one user sens 10 URL and the other 1 sends only 1, one server will have 10 url to process while the other only one.
That's if you are using HTTP/1.1 and use persistent mode on the CSS.
You can break persistency and split the url.
I run out of space and time to explain you everything.
I suggest you go read the RFC or a book on HTTP.
Also read the CSS configuration guide.
There is much more you need to know if you want to take full advantage of the CSS like cookie, ssl offloading, L7 rules vs L3/4 rules, ...
Regards,
Gilles.

How the program work ???

How the sendBytesLong works?

Hi,
The sendBytesLong() that helps to send longer data response
For sending large byte arrays as response data, the APDU class provides a special method sendBytesLong() which manages the APDU buffer.
Could you clarify how it could help the transmission? And how i should understand the term "manage" stated above that i quoted from API doc?
thanks,
-Hoang Long

safarmer wrote:
Considering you cannot set the outgoing length to more than the single response APDU length, you cannot set the length to the full buffer and keep calling send in the way you mentioned. You need to return from your process method (with the appropriate SW) before the card can receive a GET RESPONSE message. You need to be able to then receive another APDU and handle it appropriately as this will be a new call to your process method. You can then send the next piece of data and return again and repeat until all data is sent.
You can search the forum for recent posts that reference code I posted as an example for APDU response chaining.
Cheers,
ShaneHi Shane,
I thought that the advantage of "sendBytesLong(...)" method is to send data in working buffer larger than APDU buffer as you mentioned earlier. But according to the code you mentioned, applet dev still have to manage the data being sent with max length is the length of APDU buffer:
   // work out how many bytes to send this time and how many will be left
        short remain = (short) (fileSize - offset[OFFSET_SENT]);
        boolean chain = remain > MAX_APDU;
       short sendLen = chain ? MAX_APDU : remain;
        // Get ready to send
        apdu.setOutgoing();
        apdu.setOutgoingLength(sendLen);
        apdu.sendBytesLong(fileBuffer, offset[OFFSET_SENT], sendLen);
I seems that i misunderstood how the sendBytesLong works?
thanks,

How the Connector works inside ?

Hello,
now I got a sample with a BAPIRET2 table and it is working, but I have a general question to integer types. I saw that the field "ROW" is an ..._INT (INT4) and has a 4 byte length exactly how the byte store in memory. The ABAP dictionary says a length of 10. Think I'm right, that this length is only for the display ? A next point is that the offset can't be direct calulated as offset + length = offset of next field ?! in case of the field "ROW" there are 2 undefined ? bytes after the "PARAMETER" field. "PARAMETER" starts at 470 with a length of 32, so I was thinking "ROW" has an offset of 502, but in the working code I got 504 ! Why ? Will be the integer aligned to a 4byte range ? Or why there are 2 additional bytes before the "ROW" field ?
Regards
Holger

Holger,
I am going to try to help. Not 100% sure what you are asking. Here is what I know.
Within .NET you need to declare a variable that is a new instance of the BAPIRET2 table. Something like (I will use vb code....easier to read)
Dim retTable2 as new BAPIRET2
After returning the value from a function you need to loop through the table and read the values. Something like this
For i as integer = 0 to retTable2.Count - 1
Dim param as string = retTable2(i).parameter
Dim row1 as integer = convert.toInt32(retTable2(i).row)
Next
I think I have the syntax correct. I am not in front of a .net right now to verify. I hope this may help answer your question.

How the callback works in the events?

Hi,
I am in doubt that how the callback will occur internally?
Consider i am having one delegate and one static event for it.
Ex:
public delegate void raiseDelegate(String someDesc);
public static event raiseDelegate callComlpetedEvent;
And also Consider i am having 2 projects namely BMLayer and UILayer and all these above delegate and events are declared in the BMLayer and i having the reference to the BMlayer in the UILayer and "not vice versa".
Now i am subscribing to that event in one of the class which resides in the UILayer. And i am raising the callCompletedEvent somewhere in the BMLayer
and i am having the hit in the UILayer where i have subscribed.
My question is:
1. Whether the BMLayer's event will keep track the list of the subscriprions in the UILayer. If yes my another question is,
i did not add any ref of the UILayer in the BMLayer. Then how the BMLayer will communicate back or how it will keep track of those callls.
2. Or simply the UILayer will have the eye on that event which is in the BMLayer and automatically call the callback method.?
Or any other point is happening?
May i kindly know how it is working.!?
Thanks in advance,
NANDAKUMAR.T

1. Yes BMLayer event will keep track of the list of subscriptions. It need not to know about the subscribers as only way UILayer or any other dependent layer can subscribe is to provide method with same signature of "raiseDelegate" delegate. So
it always know how to call.
You can assume event as list of method which BMLayer will call once the event is raised
2. UILayer will no have eye on event, BMLayer automatically calls the callback method.

How the join works

Hi,
Could you please tell me how the below join works
Select a.col1,a,col2,b.col1,c.col1,d.col1
from Table1 a, Table2 b, Table3 c, Table4 d
where
a.col4 = b.col4 (+)
and c.col4(+) = d.col4
How do this tables are joining and displays the result.

(2) There is an outer join between c and d: rows in c will be joined to rows in d if they have the same value of col4, but rows from c will appear regardless of whether they match or not.
(3) There are no other join conditions, so there is a cross join between the result sets of (1) and (2): every row in each will be joined to every row in the other.

Trying to understand how the DDK works

Hi,
1.) If I wanted to be able to use a wide variety of NI DAQ cards
under the QNX RTOS, would the NI Measurement Hardware DDK be able to
faciliate this?
2.) From looking at the web-page describing the DDK, it looks to
me that the driver code written by NI is done in a platform indepedant
way, using only ANSI C/C++ function, and when it needs
to do something platform specific, it calls out to functions that I can
provide. Is this correct? I am envisioning having to
provide code to get PCI resources, attach to interrupt, hw I/O.... am I
on the right track?
3.) I've downloaded the NI HW DDK OTHER code, but it's not clear to me
how the platform-dependant code for QNX will integrate with this. I
have the DAQ PCI_E_series Register Level Programming Manual
and STC manual, but I can't find any docs on how to use the code in
this archive. What am I missing?
Thanks

Hi,
1.) If I wanted to be able to use a wide variety of NI DAQ cards
under the QNX RTOS, would the NI Measurement Hardware DDK be able to
faciliate this?
Depends. MHDDK provides register information for a number of NI
DAQ devices. There isn't an API that abstracts the measurement
task form the hardware, like DAQmx does.
You would need to write the high level functions for each type of
device you what to use and provide an API to your application that
would select the appropriate device specific function. I guess
something like
startDevice()
    // somehow get deviceTypeId
    switch (deviceTypeId)
    case kMSeries:
          mseries_startDevice();
    case ESeries
          eseries_startDevice();
or using function pointers, or c++ inheritance. There are many possibilities...
2.) .... am I
on the right track?
Yes. MHDDK only abstracts device access using the iBus and
tAddressSpace objects. The iBus contains the address spaces of
the device. You request address spaces from the bus and use it
write/read from the device. For PCI devices the read/write
functions using pointer manipuilation. For a PCMCIA device on a
x86 you would use the port io instructions.
iBus objects are created and destroy using the factory methods
acquireBoard() and releaseBoard(). This is where all the platform
dependent magic should occur. Here are a couple of KBs with more info:
Measurement Hardware Driver Development Kit Register Level Programming Architecture
How to Make an iBus
3.) I've downloaded the NI HW DDK OTHER code, but it's not clear to me
how the platform-dependant code for QNX will integrate with this. I
have the DAQ PCI_E_series Register Level Programming Manual
and STC manual, but I can't find any docs on how to use the code in
this archive. What am I missing?
In osiUserCode.cpp, implement acquireBoard(tChar*) and
releaseBoard(iBus *&).   To acquire the board you usually
have to loacte the device, find bar0 and bar1 , and map them to the
current address space.
This article shows exactly how to do that in QNX: Talking to hardware under QNX Neutrino
Also, create a QNX specific structure to
attach to the iBus where you can store any handles you need for
releaseBoard() to clean up.
Hope this helps.

Good resources for understanding how the internet works

Hi everyone,
I got quite a lot of spare time at my hands these days, so I thought I might learn about how the internet (and networking in general, after all I'm using the internet daily, and I've even programmed with Java sockets for ages)! Specifically, I'm probably talking about the OSI model and its components.
Historically, reading Wikipedia entries doesn't quite cut it for me, I tend to get the hang of things a lot easier with a book. So, if you know a good book (though a good online guide / explanation is fine, too), please let me know!
Cheers,
- Allan

At my uni, we use "Computer Networking: A Top-Down Approach" by James Kurose and Keith Ross for all our networking classes. I wholeheartedly recommend it; it's clear, approachable, and something you'd want to read if you didn't have to read it.

         2          0          2 > 2 > 2You can see that the query fetches one of the rows (id=1) on LEVEL=1, then all the rows that are connected to it on LEVEL=2. What rows are connected to it? Anything with LEVEL<3, that is, all rows. For each of the rows at LEVEL=2, the query tries to find rows connected to them on LEVEL=3. What rows are connected to them? Anything with LEVEL<3, that is, nothing, since 3 is not less than 3.

Want to know how the GPS works on nokia 5800?

Hi, are there any documentation explaining the working principle of how gps on nokia 5800 actually works? I want a kind of in-depth understanding...Thanx in advance.

Network based positioning is the fastest, but most inaccurate. Basically, it looks at what cell tower you're connected to, and approximates your location to be the location of that tower. The phone will use this FIRST (if you have enabled it), because it gives you an approximiate position while you wait for GPS to work.
Integrated GPS is the actual GPS receiver built into your phone. It receives signals from the network of GPS satellites and calculates your position. Due to the inherent design of the civilian GPS system, it takes time for the receiver to see enough satellites to figure out where you are. Because sometimes this time can be 5 minutes or more, the cell companies developed Assisted GPS.
Assisted GPS (AGPS) is just regular GPS, helped out by a server on the internet. Your phone will take partial GPS data (not enough to get a fix on its own), and send that data to a server (in our case supl.nokia.com). The server knows a LOT more about the exact locations of GPS satellites at any given time, so based on partial information it can compute a very good approximation of your location. This happens very quickly because a server has a much more powerful processor, and many more resources, than your phone (to put it simply). The amount of data actually sent is very very small (less than 1KB every time). AGPS helps out in getting a position fix quickly when the gps receiver hasn't been used for a while, or when you are in an area without great GPS reception.
So the order of methods used by the phone in your case is as follows. First it will give you an "approximate" position using Network Based Positioning. This will happen almost instantly. Then the phone will immediately get to work trying to get a GPS fix, and will use the AGPS server if you have allowed it to. Note that you must have an internet plan with your cell provider for AGPS to work, since it sends data to supl.nokia.com which is on the internet.
Hope that clarifies things,
Ravi

Still Trying to Learn How the Thing Works

I wrote the message below a couple of months ago, but have not had a reply. I decided to call Toshiba for help. I was told the drive only writes over files that have changed from previous saves and, therefore, has plenty of space for my meager files accumulated.
I do two versions of saves: Files and Complete System Backup. The Files process works fine; but now I receive a message saying my drive is full when I try to do a Complete System Backup. I looked at the saved files through Windows Explorer and see many copies of Complete System Backup which are obviously filling my drive. I expected only a few. Can someone help me fix this problem?
PREVIOUS MESSAGE: I have a Canvio 500GB portable backup that works just fine. However, there are no instructions on how it works and how to optimize performance. For example, how many copies of backups are made? Or does the system simply over-write previous copies? When I do a backup, I now get an indication that my drive is 80% full. How can I eliminate what I don't need so I don't fill the entire thing up? Toshiba is silent on the matter.

Not surprising you didn't get any response!
We can't see you and your backup. So we haven't the faintest idea what you're doing.
I know from reading messages here that some of Toshiba's external drives come with some version of NTI Backup Now EZ. Maybe you're using that. Or maybe you're using Windows' own backup. Or maybe you're using some third-party program. There are lots of backup programs out there.
Just in case you're using that NTI program, I did a little googling for you and found a User's Guide (attached). With a little luck, it helps.
