Records and JDBC

I have PL/SQL stored procedures that I want to access from JDBC. Some of the procedures have RECORD as OUT parammeters.
How do I call this stored procedure using JDBC and use a RECORD as an OUT parameter?
Thanks,
Blair

Unfortunately, JDBC does not support RECORD type. Even passing objects back and forth from Oracle to JAVA does not work. However, Oracle claims it does! It throws all kinds of errors - Network type error, invalid coulmn type error. It seems JDBC is meant for simple insert, update, delete operation only !

Help on RFC to JDBC and JDBC to RFC

Help on RFC to JDBC and JDBC to RFC
Hi Gurus
I have the scenario where an RFC will be triggered in SAP , to write to a DB2 database and insert new records in a table
and vice versa the JDBC has to read som data from a table based on a primary key, mark them as read for not be read next time and send the data to an RFC where a table in SAP will be updated.
I have never worked with JDBC before , pls advice.
is there any new issue to consider in PI 7.0 regarding JDBC
Thanks.

The requirement looks standard,
SEARCH IN SDN FOR JDBC scenarios,you will find many docs for sender as well as Receiver.

Count Records from JDBC Sender

Hi Experts,
I have a requirement to process 80,000 records once a month from MS SQL Server to BW.
After tuning of server and assigning the XBTM queue for the scenario didnt help much and brings down the J2EE engine everytime.
Now i am thinking of processing 5000 records at a time in a BPM (in a while loop). But i somehow need to trap the overall number of records which is not always 80k.
set rowcount 5000 SELECT * table_name where XIProcessed is NULL (SELECT COUNT(*) from table_name)
and then sending an UPDATE of XIProcessed flag to get the next 5000 rows in the JDBC sender.
I somehow need to get the total number of records and the COUNT function will not help as i am getting 5000 rows at a time and not all.
Thanks

Hi Siva,
why do you attempt counting in the BPM and adding all this overhead? Can't you just do that on the Database directly? In Oracle this is fairly easy as you can use the pseudo column rownum to limit your results. A search for rownum and SQL Server shows, that it is not as easy on SQL Server but there are still fairly simple ways to do this.
Some sources:
http://blogs.x2line.com/al/articles/173.aspx

http://www.mcse.ms/archive94-2005-3-1502710.html
From a performance standpoint i'm sure, it will work a lot better than any BPM into which you put 80000 records.

Missing "Add Records" and "Refresh Records" options for data sets post domain re-import

We recently had to re-install the Endeca server and as part of which had to export and re-import the data domains. Everything went fine except for the fact that newly re-imported data sets showcase just the "Manage Attributes" and the "Delete Data Set" options for an administrator login in. The previously available options to "Add Records" and "Refresh Records" beyond manage attributes/Delete Data Set are missing.
Thoughts? Is there a security setting to enable these?

So are you talking about the Add Records and Reload Records options for a data set in Studio?
There are no separate security settings for these options. If a user is an application administrator (is able to edit the application), then they should have access to these options.
The options are only available for data domains created using the Provisioning Service (created by uploading a file or from the JDBC or BI Server data source from the Data Source Library).
I don't know if the process of exporting and re-importing the data domains (not sure how you did that) could somehow cause the data sets to no longer know that they were created by the Provisioning Service, in which case those options would not be enabled.

Can BPM communicate with FTP and JDBC Adpater??

Hello All Experts,
I have seen a scenario FILE TO RFC TO FILE using BPM, where BPM (integration process) is having a Synchronous communication with RFC and then sends the response to FILE.
SO i just want to ask, can i use other adpater(FIle or JDBC) in BPM for synchronus communication
Plz help.
Thanks and regards,
Vanita Jain

Raj,
Let me explain my scenario clearly...
I just want to transfer a selected records from database to other system as a file and once that file is gets created than only i have to update the file-name field in database otherwise not. because there may be case when file is not gets created on other system.
so i had created a BPM which receives a records from JDBC adpater asynchronously and then send it to other system for file creation synchronously and then BPM sends a response to JDBC adapter for file name update.
But my scenario is not working, as you said FTP adpater can't be use for synchronous communication.
as Abhishek said i can use Transport acknowledgement option,but am not aware of how to implement this.
Plz help and give example(if possible) ........if you can.
Regards,
Vanita

How many records does JDBC adapter can obtain in one polling?

Hello everybody,
I need to do an interface between legacy system and SAP ECC, the legacy systems have a DB so i use the jdbc adapter (sender) and receive the information to SAP ECC with proxy, so i need to activate the polling option from my jdbc adapter working as a sender, i read a table with lot of records, and i need to know how many records does jdbc adapter support when the polling is executed, because is necessary read all records from the table and change the status of the processed field.
Is possible to get all the records from that table in one polling interval (50,000 records aprox)?, or i need to do the polling by blocks of records until finish all records from the table?, the second option, i dont have idea how can i do it.
Regards,
Vicman

Hi again!,
i still working on that, but i have a question, is possible to handle Store Procedure in jdbc adapter?? is supported?, like PL SQL, because i was working in the next query but i don't know if it works and where do i need to locate the query in the Query SQL Statement or in Update SQL Statement field or both? but how?.
DECLARE c_cursor CURSOR FOR
SELECT * FROM tablename
WHERE processed=0
OPEN c_cursor
   FETCH NEXT FROM c_cursor
WHILE @@FETCH_STATUS = 0
BEGIN
   update tablename set processed=1
   FETCH NEXT FROM c_cursor
END
CLOSE c_cursor
DEALLOCATE c_cursor

How to wrap a stored procedure that outputs PL/SQL records for JDBC?

Hello everybody,
Is there an example for wrapping a stored procedure that outputs PL/SQL records and/or PL/SQL tables of records, so that it can be called from JDBC?
Since this is not possible with the Oracle JDBC driver, Oracle recommends "To wrap a stored procedure that uses PL/SQL tables, break the data into components or perhaps use Oracle collection types." (http://download-west.oracle.com/docs/cd/B12037_01/java.101/b10979/ref.htm#sthref2123)
Many thanks for any help,
Cheers, Christoph

Hi Christoph,
Have you tried using JPublisher, or -more easily- JDeveloper (Go to your database connection in the "Connections" pane, open the "Packages" node, right click to "Generate Java...").
These approaches (at minimum, use of jpub) will generate required PL/SQL wrapper code, including SQL Type declarations. Once these are installed in the database, you can invoke the wrapper procedures directly from Java.

Record and Playback performance goes down at high frequency

Hi,
We're testing record and playback using USRP-2920( LV 2013sp1, NI-USRP 14)
To test it, we downloaded record and playback example code.
Signal source is a function generator outputting 6 MHz bandwidth 8 VSB modulation signal.
USRP Rx parameters are center = variant / gain = 0 / IQ rate = 25MHz and Tx parameters are center = same as Rx center / gain = 0 / IQ rate = 25MHz
The problem is... in low carrier frequency like 70MHz, quality of playback signal is great.
But in high carrier freqency like 2.2GHz, SNR and signal power dropped significantly i.e. they tend to drop as carrier frequency goes high.
And the strange thing is as carrier frequency is increased, a small peak on the center is increased as well.
Please check the attatched file to see the tendancy.
So.. my question is why is this tendancy occures?(we tested another USRP and the result was same as before)
and what should we do to reduce this effect?
Regards,
Youngmin

record and playback results.xls ‏469 KB

Hi,
I suggest a couple of things:
NI USRP 2920 is a non-calibrated device. So setting a gain value of 0 at different frequencies could mean a different actual gain. So try increasing the Rx recording gain (on the USRP) in cases where you observe low SNR. Similarly Tx is not calibrated.
Is the signal recording done with cables or over wireless medium ? You can try to eliminate any spurious signals if you use SMA cables while recording.
I think the power at the center of the spectrum is the DC offset. You may refer to the DC Offset/LO leakage section in the best practices section here http://www.ni.com/white-paper/13881/en/

Difference between empty plsql record and null plsql record

Hi there,
I am kinda getting confused with empty plsql record and null plsql record.
How do I assign plsql record to be empty and to be null?
create type emp_obj as object (enum number, ename varchar2);
CREATE OR REPLACE TYPE emp_type AS TABLE OF emp_obj;
Thanks

First of all, do not use term PL/SQL record in this context. Record type in PL/SQL is completely different from object type. Secondly, there are 2 states of a nested table:
1. Unintialized:
SQL> create or replace
2    type emp_obj_type as object(enum number, ename varchar2(10));
3 /
Type created.
SQL> create or replace
2    type emp_tbl_type as table of emp_obj_type
3 /
Type created.
SQL> declare
2      v_emp_tbl emp_tbl_type;
3 begin
4      v_emp_tbl.extend;
5 end;
6 /
declare
ERROR at line 1:
ORA-06531: Reference to uninitialized collection
ORA-06512: at line 4
SQL> 2 Empty:

5 end;
6 /
Nested table v_emp_tbl has 0 element(s).
PL/SQL procedure successfully completed.
SQL> NULL aplies to nested table element, not to nested table itself:

5      if v_emp_tbl(1) is null
6        then

DB Connect DataSource PSA records and DSO records are not matching...

Dear All,
I'm working with SAP NetWeaver BW 7.3 and for the first time, I have loaded from Source System DB Connect. I have created a DataSource and pulled all records and found 8,136,559 records in PSA. When I designed and created DSO with Key Fields 0CALDAY, Item No and Company Code, it has transferred records about 8,136,559 and added records about 12,534 only. Similarly following InfoCube has about 12,534 records into its Fact table. When I tried to reconcile the data/records with source DBMS for a month, the records/data could not matched?
1. What could be the reason behind the issue? why I am unable to load the records/data correctly?
2. Have I not mentioned the Key Fields of DSO in a correct manner?
3. Is it possible to load the records/data into DSO without giving any field as Key Fields?
4. How should I resolve this issue?
5. Is it could be of DSO Overwrite and summation function utilization if yes, then how to utilize it?
Many thanks,
Tariq Ashraf

Dear Tariq,
1. What could be the reason behind the issue? why I am unable to load the records/data correctly?
Ans: Check transformation once. Is there any start routine you have used or direct assignments. What kind of DTP settings you have done.
Check the messages at the DTP monitor. You will surely find some clue. Any duplicate records are being detected or not check once if you are using semantic keys in your DTP.
2. Have I not mentioned the Key Fields of DSO in a correct manner?
Ans: The transformation key and the DSo key are they same in your case?
What kind of DSO is it? Like for sales order DSO you take Order number as a key field., So you have to define the key fields according to business semantics I suppose. Do you agree?
3. Is it possible to load the records/data into DSO without giving any field as Key Fields?
Ans: I dont think so as the keys you defined will help in having unique data records isnot it?
4. How should I resolve this issue?
Ans: Please check the above as in Ans:1 please share your observation.
5. Is it could be of DSO Overwrite and summation function utilization if yes, then how to utilize it?
Ans: DSO overwriting of key figures is useful when you have full loads in picture. Are you always going to perform full loads ?
For reference would you like to check this thread: Data fileds and key fields in DSO
Lets see what experts give their inputs.
Thank You...

What is the fastest way to record and write image data?

Hello,
I am new to labview and am using the IMAQ software package to record and write data from a CCD camera to the hard drive. The end goal is a program that records and saves as much data as possible as quickly as possible, for experiments lasting on the scale of days. I have been experimenting with the snap, grab, and sequence methods of recording. To save the image data I was told by NI customer support that TDMS streaming would be the fastest method. I have also been experimenting with the TDMS VIs, however I have found the IMAQ Write File 2 VI to be faster in practice. Am I doing something wrong with the TDMS file structure? Is there a more efficient way to convert IMAQ image data to a dataform that can be written as TDMS? I am posting two of my programs to provide a clearer example of what I am trying to do. The first takes a snap of the image and appends it to a TDMS file. The second is the fastest I have found so far and uses Grab to record the images and the IMAQ Write File VI to save them.
Thanks

Hi
For me it is no surprise that the second VI is faster then the first one, the reason is you can not compare this two VI with each other.
In the first VI you work with TDMS files, in the second with png files. That would be much faster, because TDMS files need a lot of diskspace.
Second point, why do you open, write and close for eacht iteration of the for loop a TDMS file in your first VI? That need really a lot of resources, so it coudn´t be fats as well.
Save your converted pictures in one array, an after the acquisition you can save it in one TDMS file. When you need for each picture a TDMS file you have to know that this need some time to do this.
So now for the architecture of your first VI, please look to the LL Sequence.vifrom the examples (C:\Program Files\National Instruments\LabVIEW 8.6\examples\IMAQ\IMAQ Low Level.llb\LL Sequence.vi), there you can see how an acquisition of a number of images have been to do.
When you like it really fast, you make a producer/consumer architecture (see examples in LabVIEW for that).
So in the first whileloop you acquire the images, write into a queue and in the second, parallel whileloop you read the queue and save the images. (see attachment)
Hope that helps
Kind regards

I was trying to make a new screen recording using quicktimeplay, but when I watched the video after recording it all I could hear was me talking while the video was showing on the screen. How do I turn off that recording and turn the right one on? thanks

Hi j2399123,
It sounds like your screen recording is doing what it was designed to do, capture what is happening on your screen, with optional voice over with the microphone.
Screen recording is for recording what you see on the screen, it is not a "video capture" option, like for capturing a movie with sound that is playing on your screen.
For the QuickTime recording options, check out "Recording with QuickTime Player" in
Mac Basics: QuickTime Player creates, plays, edits, and shares video and audio files
http://support.apple.com/kb/ht4024
And for screen recording specifically, there's

Creating a service ; What needs to be added to tnsnames.ora and JDBC url?

DB version: 11.2.0.2
OS platform : Solaris 10
We have a 2 node RAC.
DB name   = mbsprd
Instance1 = mbsprd1
Instance2 = mbsprd2I want Instance 1 (mbsprd1) to be used for our OLTP application and Instance 2 (mbsprd2) to be used for another application of DSS nature.
Based on the syntax
srvctl add service -d <dbname> -s <ServiceName> -r <Preferred Instance> -a <Available Instance>I am going to create 2 services
-- Creating a service called OLTP
srvctl add service -d mbsprd -s OLTP -r mbsprd1 -a mbsprd2-- Creating a service called DSS
srvctl add service -d mbsprd -s DSS -r mbsprd2 -a mbsprd1-- Starting the services
srvctl start service -d mbsprd -s OLTP
srvctl start service -d mbsprd -s DSSI guess the above steps are enough to configure a service at the server side.
I would like to know what needs to be done at the client side.
Currently the tnsnames.ora file and JDBC url used by our clients are shown below. What needs to be added to tnsnames.ora file and jdbc URL to start using services configured above?

Material Group in the Info Record and PO

We have the scenario of an info record that is "standard" and "sub-contracting". When you display the info record for either category using ME13, it has the value for material group in the general data screen. Technical Assistance tells me this value is found in EINA-MATKL. However, when I do an extract for the info record from EINA, the field is blank.
My two info records (standard and sub-contracting) in EINE were created differently. The standard one was created using ME11 and a plant was entered. Because a plant was entered, the material group value was not required. The sub-contracting info record was automatically created when the PO was created (InfoUpdate button is on). In the PO, the material group was also entered; however, a plant was not added to the info record because we do not have EVO set up to include the plant when the info record is automatically created. (This is something I can change).
This is very confusing when we are looking at these info records and it appears data should be there but it is not. This most noticeably happens with the ones that are getting created automatically and then a different category is created using ME11. Are we are missing some addl requirements in configuration when these records are being created automatically????
Can someone please explain???? I need to come up with a solution to this problem.

If you want to enter diff ordre unit than in the PIR
In this case in the material master purchasing screen you have to activate the var order unit
enter 2 here
now go to your info record and on general data screen you will see the field var ordre unit
here enter 2
than click on conditon from menu
system will popup the order unit screen
here keep cursor on box and click choose
now it will allow you to maintain the box price also
once you do this than it will automatically defult in the Po upon selection.

I recorded a panel presentation on my Ipod and would like to edit the recording on my itunes so I can export the recording and send it to my colleagues over the internet. I was able to import the recording to my itunes library but need help editing it.

Hello, thanks in advance for your help. I recorded a panel presentation on an ipod and would like to edit the audio recording to just one portion of the recording. I was able to import the audio into my itunes 11.1.3 music library but I have not been able to edit the length of the recording. I followed an online tutorial and was able to edit when the recording starts and stops on the recording but I haven't been able to edit out the parts of the recording that I dont want. Also when I try to export it to my Desktop or to Garageband (not sure if that helps or not) I am not able to export it. It is currently a .WAV file. I would like to edit the length of the recording and then export the file onto my desktop. I would like to email the presentations to my colleagues online so I could also use advice on how to make it a smaller file since it is current 945.6 MB.

iTunes isn't an editor. You need an app that's intended for editing audio files, like Adobe Audition (http://www.adobe.com/products/audition.html) or Audacity (free in the App Store).
