General managment on data in a program?
Hello
How does programs handle vast amount of data? What general principle is followed? Do they read/write to temporary files, has database something to do with it (I do not know how a database work)? After all, you do not need much effort to run out of heap-space in Java. If I were to learn some of these strategies, what conceptual word would I google for? Or maybe you have a book you think is appropriate? To me, without any proper IT education, its a bit of a mystery :)

Handle which kind of data to do what?
To me, without any context, it's a bit of a mystery
as well.Well, any kind of data. Let us say I want to create a GIS. That involves alot of numeric data. Let us say I want to performe statistics on a numeric dataset ~100Mb. Etc etc.
Does different data require different handling?

How to install "Compact FieldPoint Embedded Data Logger Example Program" on cfp2200
i finally managed to get max to see the devices of my cfp2200.
(i had to disable every unused networkadapter due to overlapping subnets)
now i want to deploy the example programm "Compact FieldPoint Embedded Data Logger Example Program"
http://zone.ni.com/devzone/cda/epd/p/id/3221
i therefor have tried to install the runtime 8.5 on the target. however this is not possble, because i have labview 2010 installed and it gives the message:
"the host has a newer version available"
ok. runtime 2010 should work to - not?
i open a new project - import my *.iak-file and drag-n-drop the content of "cfp_data_logger_source.zip" onto the target.
now if i open the file cFPEmbeddedDataLogger.vi the run-button is cracked and by pressing it an errorlist opens.
the errors say stuff like:
target does not support this function/subvi
and
vi has been modified with a different applicationinstance
please help me to make this work.
i know that it is possible to get the programm to run on the cfp2200 even dough it is primaly designed for the cFP-2000, cFP-2010, cFP-2020, cFP-2100, cFP-2110,
cFP-2120.
big THANX already for you help !!!!!Hi, thanks for your help=) I've manage to drag the file into my targeted controller. I am now doing the setting of the data logger program, but there's one thing I'm unsure of. May I know what does it mean by the cFP controller clock? http://zone.ni.com/devzone/cda/tut/p/id/3219 . Thanks. =)
Log On Startup
Start logging when the controller powers up.
Start Log Time
The time to start logging.
Stop Log Time
The time to stop logging.
Note: Make sure the clock is set correctly on the controller. The settings described above refer to the cFP controller clock.
Log Rate
The number of milliseconds to wait between each acquisition.
FP Drive For Data Files
The drive to store the log files in. The C: drive is the default for all cFP controllers. If you want to save to the removable CompactFlash drive on the cFP controller, select the D: drive.
Digital "Pause" Line
The Digital Input item to use as a "pause" button for data logging. Logging pauses when the signal is high. When the signal goes low again, a new file is created and logging continues if appropriate.
Note: Use only Digital Input items for the Digital "Pause" Line.
Tip: You can use DIP Switch 3 to block the current data from being logged. This switch works the same way as the Digital "Pause" line.
Logging Session Tag
Is stamped on the spreadsheet that the data logger creates. -
SQ02 Data retrieval by program
Hello,
I would like create an abap query 'SQ01' using infoset 'SQ02' with the option
'Data retrieval by program' and 'Integrated program'
I wrote and tested this program:
REPORT ZONR_REPORT_MBEW.
data: mbew_tab like mbew OCCURS 0 WITH HEADER LINE.
* <Query_head>
select * from mbew into table mbew_tab
where bwkey = 'MANT' and bklas = '3000' and matnr = '000000000001027712'.
call function 'MBEW_EXTEND'
exporting
XVPER = 'X'
tables
mbew_tab = mbew_tab.
loop at mbew_tab.
* <Query_body>
endloop.
Could you help how to fill the area 'Data structure' of the option
'Data retrieval by program' ?
With the menu 'Goto' -> 'Code' -> 'Data readindg program'
I found this template of program :
REPORT RSAQDVP_TEMPLATE .
* declarations
* (insert your declarations in this section)
data:
MBEW type MBEW ,
it_data type standard table of MBEW .
field-symbols: <struc> type MBEW .
* selection screen statements
* (define your selection-screen here)
* !! the following comment MUST NOT BE CHANGED !!
*<QUERY_HEAD>
* read data into IT_DATA
* (select your data here into internal table IT_DATA)
* output of the data
* (this section can be left unchanged)
loop at it_data assigning <struc>.
move-corresponding <struc> to MBEW .
* !! the following comment MUST NOT BE CHANGED !!
*<QUERY_BODY>
endloop.
Could you help me to customize the program ZONR_REPORT_MBEW according
to the template, because I'm a neewbie in abap ?
Thanks for your helping
MarcoThe "Data retrieval program" would be coded like any normal report except for adding a few comment tags that will be used by SQ01 query generator as placeholders to insert its own code into your code to generate the query program.
In general this is how a data retrieval program is coded. SQ01 when it generates the query will insert its own code in place of *<Query_body> and *<Query_head> comment tags
REPORT ztest_sq01_driver_program.
TABLES: <name of dictionary structure of your infoset>.
* DATA declarations
START-OF-SELECTION.
*<Query_head>
* <Fetch your data here and store it in an internal table gt_report> that has all the fields that you need in your query
END-OF-SELECTION.
LOOP AT gt_report INTO gs_report.
MOVE-CORRESPONDING gs_report TO <name of dictionary structure of your infoset>
*<Query_body>

SQ02 - Create InfoSet using 'Data retrieval by program'
Using SQ02, I would like to use the data returned by an ABAP program as the data source for an InfoSet. When attempting to create an InfoSet, I noticed the 'Data retrieval by program' option. I would like to discover how to use this option and how to pass parameters to the ABAP program I'd like to use.

When I try to download a software up date for another program in Binary File (eg. C Cleaner or a Microsoft file) in Firefox they all just come up in the download window as 'Canceled'? When I go to the destination folder the download file icon is there with 0 Kb's for size...Then when I click 'RETRY' the download it appears to download fully, but when I go into the destination folder the downloaded file is not there? I need to know if there is something in the Firefox options to resolve this problem or much more!!
If all .exe files are blocked, antivirus software is most likely configured to block them. See if you can download these with your antivirus and/or security software disabled.

Difference between general DB and Data Warehouse DB
Hi,
We have a server on which Oracle Database was already installed. We want to use it as a data wareshouse. I had a question that if this database would be sufficient for a data warehouse or i would have to create a new database for data warehouse. Is it possible to find out if the installation was general purpose or Data Warehouse?
Also if i go ahead then would it impact if i directly install the new database without uninstalling previous oracle database.
Appreciate your help
regards,
Edited by: user10243788 on Mar 23, 2010 2:09 AMWhile installing you can select any one 'General Purpose' or 'Dataware house', the only difference in those two while installation is that the parameters for init.ora will be having high values for dataware house database, which can also be updated later manually. So you can go ahead and install general purpose database aswell but later you need to modify the init.ora parameters for specifying higher memory values for parameters like shared_pool_size, java_pool_size, db_buffer_cache etc.

Problem in mapping from import manager to Data manager
hi friend's....I got a problem while mapping the data from import manager to Data manager .The problem is the data in import manager (i.e source hierarchy) will map to single filed in data manager ( i.e target hierarchy)..
Help me it will be great full to me
Regards
YugandharHi Ana,
If you have a hierarchy in this format:
N1 N2 N3
A A1 A11
A A2 A21
A A3 A31
B B1 B11
Then u have to follow these steps for import.
1. Select source file and destination hierarchy table at top of import manager.
2. Go to Partitions tab (Second tab) Just above the tabs, if u click on the plus sign against your source file, you will see N1, N2 and N3. Cick on N1 and in partition tab, add N2 to right side by double clicking on N2.
3. Now add N3 to right side by double clicking on it.
4. Go to field mapping (Third tab). There you will see a field N1(Partition). Map this field to yourhierarchy field on destination side.
5. In value mapping (Below the field mapping), Expand your source hierarchy. Select all (ctrl + A). Click on "Add" button. Select "Add Branch as child" option.
6. Go to Matching tab (Fourth tab). only one field will be there. take ity on the right side. and select the import action as "Create".
7. Go to last tab. Click on import button.
Your hierarchy has been imported. You can check it in data manager (in hierarchy mode).
Hope this solves your problem.

Using internal table data in difrent programs
hi ..
I am running a program that does many things and I need to use the data in one of the internal tables in another program.
You may say why?
Because I need to make sure that the first program runs successfully then I need to generate a report with that data in separate program.
ThanksHi Mohammed
Another approach for the solution:
1. Which John has mentioned in his first post. You can use the ABAP memory. For this inspect "IMPORT ... TO MEMORY ID ..."/"EXPORT ... FROM MEMORY ID ..." statements.
2. Fill a range object and send it as the select-option at the interface of the second report using SUBMIT (which John also mentioned).
3. May be you can use shared data areas.

Changing data in called program
Hi Gurus,
I have an exit where I want to change the main program's internal table data dynamically in this exit FM.
In short, I want to change the internal table data in calling program being in called FM.
Can this be done? If so how?
RegdsYou can change the data in a field in a program using field-symbols. The field-symbols acts as a pointer to a defined field. Change the field-symbol value will in turn change the value of the field. You can also assign the value of a field from a different program ( at runtime ) to a field symbol. But I beleive that in this circumstance changing the field-symbol will not change the actual field value.
I had this same problem myself. -

How we can manage SharePoint data if we have thousands and thousands of files in a Library
Should we archive the data. If yes? How?
Can we create hierarchy?
It is the case if we have thousands and thousands of files in our SharePoint.
Also what would be the best way to query the data in this case?
ThanksYes, archiving is an option to manage huge data. However there are some best practices available to manage huge content. Proper planning and structure will provide the best results. Term Store, Taxonomy and Metadata tagging will help to have structure
for the information. Refer to the following posts for more information
