Few doubts

dear experts
1. what is the exact difference between sy-tabix and sy-index. explain in detail.
2.diference between sm36 and sm37.
3. on which server we exactly do UTP(unit test planning) what is the procedure.
thankx

Hi,
Here is an example from which you can understand the difference between sy-tabix and sy-index.
Itab is an internal table with the following data in it.
id   Name
198   XYZ
475   ABC
545   PQR.
loop at itab where id > 300.
write :/ itab-id, itab-name , sy-tabix, sy-index.
endloop.
My output will be :
475 ABC 2 1
545 PQR 3 2
Sy-tabix is the index of the record in internal table.
sy-index gives the no of times of loop passes.
So, for the first record in the output (475 ABC), 2 is the index of the record in internal table and as it is first time loop pass occured, sy-index value is 1.

A few doubts in the 'beginners guide'

Hello, I'm trying out arch (still with virtualbox), and I'm following the 'beginners guide' on the wiki.
I managed to install it but ended up with a few doubts, about some parts of the installation.
On the "Partition Hard Drives" part, it says that there are 3 types of disk partitions (primary, extended, logical), but when I'm creating the partitions with cfdisk, I can only choose between primary and logical. Does the extended gets created automatically when I create some logical partitions?
When I have to set the filesystem mountpoints, I think that I don't do anything to the /dev/sda (I only set the ones with numbers at the end - the partitions), but I don't think the wiki is clear on this, the only thing I see there is this part: "Recall that partitions end in a number. Therefore, sda is not itself a partition, but rather, signifies an entire drive" which is easily overlooked when you don't understand much.
When you need to choose the mirrors (/etc/pacman.d/mirrorlist), the wiki doesn't tell much. For example, what is the difference between choosing ftp or http servers? do you choose both? In the beginning there's a server that has as a comment #any, does this mean it will choose automatically which server it will use?
that's it... for now :)

moosie wrote:For the hard drive part, someone correct me if I'm wrong, but sda refers to the whole drive where as sda# refers to a partition, one might say portion, of this drive; i.e sda1 would be the first partition sda2 the second and so on. As for the mirrors for the difference between ftp and http refer to this link: http://daniel.haxx.se/docs/ftp-vs-http.html I haven't read this but it seems to be a good source of knowledge. Also for the mirrors and the install as a whole I recommend watching this youtube video: http://www.youtube.com/watch?v=RjTTl_9aUXc in the video the reflector and curl are used to come up with the fastest mirrors based on your location and he goes through the whole installation process all the way to the point where he installs gnome.
In general, if you're not sure of something, better not to post it. Also, don't do googling for someone else, Arch users are expected to be competent to do their own research. Else you end up feeding help vampires (not necessarily saying the OP is one).

Need clarification on few doubts in OLM

Hi,
I would like to get the following doubts cleared. Thanks a lot in advance for any information related to these:
1. How can OLM help in identifying the training needs for the organization?
2. In the web based interface for learning Administration how can we search for all Courses/classes/categories etc? (*, % etc do not help only partial or exact match helps)
3. Could not find the Cost Transfer Finance Headers page to create a Cost Transfer finance header in the Oracle Learning Management Administrator Menu. Where is this page?Is this available only with OTA.J and later?
4. Could not find the form for restricted class. Is this available only with OTA.J and later?
Thanks & Regards,
Supriya

Hi Supriya,
Regarding 1:
Training needs will be identified in Oracle HR and not in OLM. OLM will only record training and the associated competences and deliver training with specific competences.
There are two ways of identifying training needs in Oracle HR:
1: Get an overview of all competences in your organization, and use this info for your own estimate of the total training need.
2: Let Oracle HR find the training need for each individual by comparing individual competences and the required competences for the individual job, then you can add these up to a total for the whole organization.
You can do both from the “suitability match” functions in Oracle HR Self Service
Regarding 2:
In order to avoid excessive response times it’s no longer possible to use “%” as the only input in some of the searches.
If you want to have the full list, I will suggest you use the Advanced Search instead of the normal search. In the Advanced Search you choose your “Object Type” and a “Start Date” of 1990 and leave the rest of the fields blank. This will give you a full list of courses or classes.

Hi Experts...Im new to SAP BW & BI...I have few doubts how u guys can clear

HI Experts,
Can anyone explain how these updates works..
FULL Update,
Delta Update,
init update,
initialize with data transfer,
intialize without data transfer.
V1 Update
V2 Update
V3 Update.
Thanks
Manu

Hi...
Full Update >> Loads all the data from the source system..every time you run a Full upload it will pick old as well as new changed records from the source system.In this case generally number of records is huge and IP takes a long time to get completed...
In this case each time we need to fill the set up table in the source system..
Delta load >> Delta loads only brings the changed records from the source system.To initialise a delta load:
1) first run full load
2) then run init IP without datatransfer
3) run delta load...
In this no need to fill the set up table repeatedly..
Just fill it once first time when you are executing full load..after that when you will run init IP...delta queue will get generated..
It saves time...
One thing I want to mention here...
Suppose any delta loads fails...then it is must to make the toatal staus in the IP monitor manually red before deleting the request from the target....to set back the init flag...otherwise it will not allow repeat delta and data will be lost
In full load if you no need to make the Total Status manually red.
Init update is to set the Init flag...
Suppose somehow delta mechanism got corrupted...
In this situation we have to delete the init flag >> If last failed delta load picks some records...then we will do delta with data transfer...if last failed delta IP picks 0 records...then we will do delta without data transfer...
After running the init IP...we will run Delta IP...
V1 Update >> Synchronous update >> Taking an example -
If you create/change a purchase order (me21n/me22n), when you press 'SAVE' and see a success message (PO.... changed..), the update to underlying tables EKKO/EKPO has happened (before you saw the message). This update was executed in the V1 work process.
V2 Update >> Asynchronous update >> There are some statistics collecting tables in the system which can capture data for reporting. For example, LIS table S012 stores purchasing data (it is the same data as EKKO/EKPO stored redundantly, but in a different structure to optimize reporting). Now, these tables are updated with the transaction you just posted, in a V2 process. Depending on system load, this may happen a few seconds later (after you saw the success message).
V3 Update >> Batch asynchronous update >> V3 is specifically for BW extraction. The update LUW for these is sent to V3 but is not executed immediately. You have to schedule a job (eg in LBWE definitions) to process these. This is again to optimize performance.
V2 and V3 are separated from V1 as these are not as realtime critical (updating statistical data). If all these updates were put together in one LUW, system performance (concurrency, locking etc) would be impacted.
Serialized V3 update is called after V2 has happened (this is how the code running these updates is written) so if you have both V2 and V3 updates from a txn, if V2 fails or is waiting, V3 will not happen yet.
Kindly assign me some points if this helps you...
Regards,
Debjani...

Kernel Upgrade : Few Doubts

during kernel upgrade.
I renamed original kernel exe to exe.old > mv exe exe.XX
downloaded two SAR & uncarded files to a directory and renamed it to exe. > mv exe.YY exe
after found there were multiple files were missing in new kernel.
is that some thing happen ?

Hi
As Nicholas said dont rename the exe folder,after extracting new kernel files just copy those files into your exe folder,because two files what you have download doesn't give all files which are necessary to start the SAP.
So you better extract files into new folder,copy those files into your exe folder using below command.
>cp -rp <newfiles> /sapmnt/<SID>/exe
some times it may give warning saying that some files cann't be replaced because files are in use.
Then just note down that file names and rename that file in exe folder like below.
>cd /sapmnt/<SID>/exe
>mv <filename> <filename>.old
Again you copy new files to exe.
>cp -rp <newfiles> /sapmnt/<SID>/exe

Schema and Table .. Few doubts.

Hi ,
Can you please help me out on following questions.
1. How to physicalizing the Logical Model into database Schema AND Tables
2. How to create a Schema and table in oracle 11g. Let me know if scripts are available.
3. How to create a read only user with different restricted access.
4. How to deploying the Schema, Tables (and potential scripts) into Exadata.
Please provide the aboce details.
Thanks in advance.

Python(3) clipboad manipulation - a few doubts

My programming is generally messy (and very procedural), but I've been having to pick up some basic Python for a course that I teach. Since I've always heard that python makes simple utilities dead-simple to write, I decided to try one out on my own.
PROBLEM DESCRIPTION:
I copy some song lyrics/chords from a db-management app (opensong, its in the AUR) to paste it in libreoffice for formatting and eventual distribution/printing. The format is as below, basically lines starting with periods are chord lines, and lyrics may have spaces/underscores added to do alignment (see extra spacing between 'is' and 'to' in third line and the underscores on 4th line). Sections are listed like [C] for chorus or [V1] for verse 1.
[C]
.C G/B Am C/G
Jingle bells, jingle bells
.C F/G
Jingle all the way
.F F/C C C
Oh what fun it is to ride
. G G F/A G/B C
In a one-horse o___pen sleigh
So, its convenient to sometimes have just the lyrics, which means removing all chords lines and the multiple-space/underscore characters. In addition, due to the way libreoffice treats the initial text when I paste it, I get windows line endings (and when saving, reopening I get additional spacing because of that).
So here's what I have, all messy and basically uncommented, but should be simple enough to follow. And it works!:-
import sys
from PyQt4.QtGui import QApplication
app = QApplication(sys.argv)
clipboard = QApplication.clipboard()
text = clipboard.text()
splittext = text.splitlines() #deals with windows newlines if they exist
newtext = ""
for line in splittext:
if line[0] != ".": #remove chord lines
oldchar = " "
newline = ""
for char in line:
if not (char == " " and char == oldchar) and char != "_":
newline += char
oldchar = char
if newtext != "":
newtext += "\n" + newline
else:
newtext += newline
clipboard.setText(newtext)
sys.exit(app.exec_())
My questions:-
1. Am I 'wasting' code at any point? (subjective I know)
2. Without the sys.exit call I get really weird behaviour, where 'setText' would seem to grab the selection and I'd then have to re-run the app again (and get an error on clipboard.text() before I could actually use the mouse to select anything. This was the same behaviour I got from using pyGtk, actually. Does it have something to do with both QT and GTK assuming they're being used in graphical apps?
3. It seemed to me while doing my searching that the documentation for pyGTK is much better than that for pyQT, did I miss something (a good pyQT wiki or example website, for example)?

Stebalien wrote:1. If you are willing to use a regex and some list comprehension you can get rid of the for loops:
Thanks, will take a look at this after I'm back from lunch.
Stebalien wrote:2. IIRC, X11 doesn't store the contents of the clipboard. When an application puts data on the clipboard, it must stick around to provide the data when requested by another application. This is probably the source of your problem.
I'm aware that X11 only stores (for want of a better word) a pointer/reference to the app providing the data, but as far as I can tell my python application does seem to hang around. Will test that a bit, if this theory is correct, though, wouldn't that mean that sys.exit would mean what's in the clipboard (and from my small pthon script) is deleted? Because it's still usable even after the script finishes
Stebalien wrote:3. Just read the C++ QT documentation. The method calls are approximately the same in python.
I've come across all the C++ documentation, did not realize it was approximately the same. Unfortunately that means that its missing what (IMHO) is the best part about the pyGtk document, small code fragments which can be tried out...

Few basic doubts about accessing AM from backing bean class

Hi ADF experts,
I have just started working in ADF Faces.I made a sample search page.My page is attached to a managed backing bean. I have attached command button on my page to a custom method in backing bean class.
So on, click of button this method is called in backing bean.Now, i have few doubts:
1)How to get values of various UI beans in this event code?
2)I am accesing AM , in my method with this code:
FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext extContext = facesContext.getExternalContext();
Application app = facesContext.getApplication();
DCBindingContainer binding = (DCBindingContainer)app.getVariableResolver().resolveVariable(facesContext, "bindings");
//Accessing AM
ApplicationModule am = binding.getDataControl().getApplicationModule();
iS this correct ?
3) After getting handle of am how to call my custom method in AM Class?there was "invokeMethod" API in application module class in OAF, is there any such method here?
Please help me.
--ADF learner.

Thanks for ur response Frank, actually I am from OA Framework back ground.It would be great if help us a little with ur valuble thoughts.
OA Framework also uses bc4j in model layer of framework. We have a requirement where our existing developers from OA Framework have to move to ADF to make a new application where time lines are quite strict.If this would not be possible we will switch to plain jsp and jdbc,but our tech experts say ADF Faces is the best tech.
In OA Framework, Application Module is key class for all busiess logic and Controller is used for page navigation. So, I m just trying to find the same similarity , where we write we add all event codes in custom action methods in the backing bean class of page, which we consider equivalent to process form request method in Controller class of OAF.
But there are two things, I still want to know:
1)While page render, how to call specific AM methods(like setting where clause of certain VOs)
2)In action methods, the way i described(I found that in one thread only)to access AM, what is wrong in that?Also, I went through
http://radio.weblogs.com/0118231/stories/2004/09/23/notYetDocumentedAdfSampleApplications.html
where coule of examples use similar approach to access AM from backing bean class and call custom methods of AM(Doing various, deletes etc from VOs).
3)In these methods can we set any property of beans on the page, I am asking because in OAF, generally we use PPR for js alternatives.But all properties of beans cannot be set in post event.
Thanks and Regards

4.how many message types available ? what are they ?
5.when call transction or Call session can be used ? how to decide which method is best for requirement ?
could you please help me out . if u have any material or links forward to [email protected]
Good Rewards for best answers
Thanks ,
Sunitha

Here are the answers to your questions.
1. how to handle error messages in Call transaction and Call Session method .
--> In Call transaction, if you see the command, messages are populated into an internal table. You need to read last record of this table. Using Function module FORMAT_MESSAGE, you can get details of the message. For session method, session gets created and status of session can be seen in transaction SM35. You can process erroneous sessions from here.
2. which logic can be used to handle the table control in BDC method . when table control required ? let me give few transction related to table control of BDC.
--> Check these links which explain in detail with examples.
BDC - TABLE CONTROL
In BDC table control
3. what is structure of BDC DATA ? what is diffrence between BDC Session and Call Transaction method in programming steps ?
-->PROGRAM - Program Name
DYNPRO - BDC Screen number
DYNBEGIN - BDC screen start (Flag)
FNAM - BDC Field name
FVAL - BDC Field value
4.how many message types available ? what are they
-->
A (Abend) Termination
E (Error) Error
I (Info) Information
S (Status) Status message
W (Warning) Warning
X (Exit) Termination with short dump
5.when call transction or Call session can be used ? how to decide which method is best for requirement ?\

Hi ajay
Use
Set current filter settings. A row of the table describes the selection conditions for column entries that are not to be displayed.
You should never manually set up the internal table with the filter settings. Use this method only to set filter criteria that you got using get_filter_criteria or a layout.

Q5) What is BPM ??? In Which Situation We Will use BPM ??? Tel me in General Words
BPM process is a very useful tool as the name suggest ccBPM when ever you want to model your soultion hitting different systems, Also helps in controling and monitoring complex integration solution process.
As it uses SAP workflow engine behind it is very effective in building complex soultion.
some simple scenarios could be
Wait for more than one input and start your integration process..
Raising alerts, exceptions and so on...
BPM is necessary when you re looking at stateful-message
processing i.e; the state of message is persisted for
making some decisions or routing etc.
Some examples:
Merging of two files into one.
Splitting of single file and sending to to many receivers
parallely or sequentially.
Doing complex business process which involves inserting
data into some system>getting response>using response
payload to determine what step needs to be done-->
determining receiver-->sending message.
Well such a process will incolve steps like sync send,switch,send etc.
Sync-Async bridge is one other example of BPM..which
can't be donw without BPM
Well, one can give 'n' number of examples...but what u
got to understand is BPM will involve some process steps
for manipulating the messages and BPM is also a logical
sender/receiver like a business service/sytem.
I would suggest you to do BPM patterns in the basis
component to get more familiar with BPM
Cheers...

Doubts in GeoRaster Concept.

Hi everybody,
I have few doubts in GeoRaster concepts.
I did mosaicing of multiple Georasater objects using "sdo_geor.getRasterSubset()" and able to display image properly. But while doing this I come across few people suggestions. They said that mosaicing multiple rows together in a GeoRaster table is not going produce meaningful results because the interpolation methods wont have access to the data in the adjacent cells at the seams because cell needed exist in a different row (i.e. where two rows of GeoRaster either abut or overlap).
I assume Oracle takes care of all this. Please suggest wheather my assumption is true or the statement given is true?
Regards,
Baskar
Edited by: user_baski on May 16, 2010 10:49 PM

Hi Jeffrey,
Requirements:-
I have to do mosaicing of 'n' number of Georaster objects. For eg, if table has 4 rows of GeoRaster object, then i have to create single image by mosaicing all the Georaster object based on the Envelope provided. (Note: I have to do this with Queries without using GeoRaster API)
Workflow:-
1. Get the connection and table details.
2. Retrieve necessary information from the db like SRID, MAXPYRAMID, SPATIALRESOLUTION, EXTENT etc. For getting extent, I used SDO_AGGR_MBR function.
3. With the help of "MDSYS.SDO_FILTER" and bouding box values, I create arraylist which contains raster id's retrieved from raster data table which covers the bouding box value provided in the filter command.
4. Then I passed bounding box value into "sdo_geor.getCellCoordinate" function and I retrieved row and column number of Georaster image and created a number array which contains starting and ending row/column numbers.
5. Then I had written a PL/SQL with "sdo_geor.getRasterSubset" function which takes the number array and raster id as input parameters, which inturn returns BLOB object.
6. I am executing step 5 in a loop with all the raster id's that I got at step 3. For eg, arraylist size is 4, then I will have four BLOB object.
7. Finally, I creating new image from the BLOB objects after some scaling and cropping based on the individual GeneralEnvelope of each raster id object.
I had followed all the above steps and successfully created mosaic image.However, few people suggested that mosaicing in this way does not produce meaningful results because the interpolation methods wont have access to the data in the adjacent cells at the seams because cell needed exist in a different row. I assume Oracle will take care of these things. Moreover, they suggested to keep single row in GeoRaster table instead of muliple rows of Georaster object and suggested to use "SDO_GEOR.updateRaster" function to update a part of the raster object and the pyramids are rebuild automatically.
So Please suggest which is the better way to do mosaicing. Wheather my assumption is correct or not?
