Need help about RRD4J, get data from rrdb

how i can get that data from that database, and move them to another database file data2.rrd.
can i do this?

thx jschell
javadoc from rrd4j not clearly enough for me to understanding about prosesing add, update and get data in there, so i ask in this forum may be anyone can give me solution.

i just want to get data that i had put in data1.rrd to move them to another rrd, example: data2.rrd.
data1.rrd and data2.rrd, they have same lastupdate time.

Hi,
Thanks for the answers. I tried loading it yesterday, i had lot of confusions.
What should i do to load a master data from a R/3 to BI7.0.
1. Created a Info object named (EKKO_mas) with some attributes (ernam, ekorg, lifnr).
2. Go to info provider and right clicked on info area and selected insert char as data target. (Please correct if i am wrong).
3. Login to R/3, go to sbiw generic data source created one with a view/table as EKKO and map the application compound and select the needed fields by checking the checkbox. (please correct if wrong).
4. Go to source system tab and replicate data source. ( Please correct if i am wrong)
Then what should i do.
guessing steps:
4. Create a Data source, in BI 7.0 . In that as i am not using flat file, should i select "application server" instead of "local workstation" . In field tab i specified all the fields given in Info object. ( Will there be anything else i should do or change in this tab)
5. Load data in PSA. ( will the data from R/3 i selected loaded in PSA without any problem)
6. Create transformation , save and activate.
7. Create DTP save and activate , click execute.
By doing the above given step will i be able to load the master data from R/3 to BI 7.0 data target (IO) . Please help me if something is wrong with my steps.
Thanks.

Need help on Adhoc Request functionality in PI

Hi Experts ,
Need help on the design approach . How can PI handles if Sender System prefers to send an Adhoc Request(Outbound) to PI .
Here is the complete requirement .
" An Adhoc Request is send to PI from the Legacy Sender System (Whenever Legacy system has Planned and unplanned shutdowns) . Legacy system uses web client based request ( HTTP ) to PI . As soon as the http request is received to PI . PI needs provide back the information to Legacy System "
Note : PI needs to provide the Requested data to Legacy system from the External Shared folders . (Data content is stored in an .xml format in shared folders)
I can see file adapter is one of the option which i can choose to connect to the external folders .
How can i achieve the Adhoc Request functionality ? Needs advice and suggestions on this please ?
Regards,
Khan

Hi Aziz - I don't think you should worry about "Ad hoc" here. It's nothing but a specific request from your sender application.
Please refer to the scenario #8 SOAP- File and i assume it would be the same case with your interface.

Need help in URL Service Data Control

Hi Everyone,
I'm working on JDev11gUp2, ADF-RC
I am using URL Service Data Control to fetch data from CSV File and i got success but I need to know that is there any way to pass File Connection URL Dynamically at run time, As i know we have to provide URL string at design time, but i have multiple files to pass at run time , Then?
And one more question that Once the data is uploaded into af:Table from my CSV file. then after Any data change in CSV file must reflect in af:table with that change like other iterator refresh functionality. but I'm not able to do that, Simple question is, How to Re fetch the data from CSV file at run time?
Your answer would be really appreciated as it would really help me.
Thanks
Fizzz...

Hi Fizz,
Not sure of the answer to your specific question. A couple of thoughts, though:
You could try putting some code in a backing bean action listener to get the data control from an iterator binding (where you have added an iterator binding to your page definition) and then using the debugger to inspect the runtime type of the data control returned - then look to see if that type has a setURL method.
[url http://database.in2p3.fr/doc/oracle/Oracle_Application_Server_10_Release_3/web.1013/b25947/adv_data_controls005.htm]this link talks about creating your own data control type - where you could certainly expose a method to set a URL. More work, but you have complete control.
Hope this at least gives you an idea or two.

Sending binary data from JSP (1.1)

Hi all:
I am using Tomcat 3.2.1 and Apache under Linux Mandrake OS.
I have a JSP (1.1) sending binary data (GIF, PDF, DOC ..) using response.getOutputStream().write(data)
method.
The problem is the precompiler automatically creates the JspWriter and puts some out.write("\r\n") lines
before I use getOutputStream method. The JVM throws an IllegalStateException because I am using both
methods (this is from Servlet 2.2 specification).
Must I change my code to forwarding to a servlet that make this work or is there a simple solution to
avoid this?
Thanks in advance.

Hi Shreeharsha
Please refer to below docs for sending data from JSP page to RFC. In which you need to use sap connectors for connecting to SAP backend system.

Extractor class to fetch the data from PA0105

Hi All,
Can anyone suggest me the extractor class used to fetch the data from the table PA0105.
Any information regarding this will be highly helpful.

If you give PA0105 all data will be extracted.
Or if you need any specific data you need to know the filed names first. check the table from SE16 for identifying the field names. and do it accordingly.
Please reward points

Do you have StockDs configured in your server config.xml?
I think the query should look more like this:
SELECT stocks.SYMBOL, stocks.EXCHANGE
FROM STOCK as stocks, ExchangeStream [Now] as datastream WHERE stocks.SYMBOL = datastream.SYMBOL
