Data transfer between datbases?

Hi,
Here's my question:
I have 2 databases.DB1 and DB2.I have 1 table in each with the same name and same structure .Lets say the table name is "STUDENT".Student table in DB1 has 100 rows in it.Now useing SQL ,i want the Student table in DB2 to contain the same data as the data contained in Student table in DB1.
How can i use an insert with a select statement to accomplish the above task.
Suggestions appreciated.
Thanks,
Aparna.

You'll need to define a database link between the two DBs and a synonym.
Then you just do :
Insert into student(columns,...) Select * from db2.student;
The key is the database link

Error 33172 occurred at Read & Write data transfer between two or more PF2010 controller

Hi,i need to do data transfer between two or more FP2010 controller.e.g. FP2010(A) & FP2010(B).
FP2010(A) need to transfer the measurement (from its I/O module) to FP2010(B) to do the data analysis.These data transfer should be synchronous btw two controller to prevent data lost.
From the vi used in the attachment,i encountered some problems at:
(1) Error 33172 occurred while publishing the data.Can i create and publish data under different item name?
(2) How to synchronies the read & write btw contorller?
All controller are communicating with each other directly without the need of a host computer to link them together
Is there any other method to do fast data transfer betwe
en controller?

Hi YongNei,
You were succesful in omiting enough information to make it very difficult to answer!
Please post your example.
Please tell us what version of LV-RT you are using.
Please define what you concider "fast data transfer".
Have you concidered mapping the FP tags of FP2010(A) to FP2010(B) and vise versa?
WHat exactly has to be syncronized?
If you have something that is close to working, share that.
Well, that as far as I can go with the info you have provided. Depending on the details, what you are asking could be anything from trivial to impossible with the currently available technology. I just can't say.
It would probably be a good idea to start over with a fresh question (sorry) because not many people are going to know what a a "
PF2010" is and I can not guarentee that I will be able to get back to you personally until next week-end.
Trying to help you get an answer,

Data transfer between SAP & Java and Vice versa using IDOC Process

Dear Experts,
        We are working on one of the good requirement related to data transfer between SAP and Java software. Client requirement is, they want to transfer the data in both the ways (from SAP --> Java and Vice versa also).
In detail is, after sales order creation using one custom program loading plan details will be calculated. Once loading dates are confirmed then, user will release the sales document to transfer the data from SAP to Java using "Outbound IDOC processing". Similarly in that JAVA software some shipment details will be performed, once completed from JAVA software again details needs to be pumped back to SAP as "Inbound IDOC Processing".
For this fields are already identified from external software SAP and we are looking for the same to perform the steps in SAP.
At this stage, I need your expert opinion / feedback how to go about at this stage.
Meaning,
                 1. What are the customizing steps needs to be done in SAP..?
                 2. How to trigger the :Outbound IDOC process" once the documents are "Released" from custom transaction
                 3. How to create the link between SAP and JAVA to transfer the data between these 2 software
                 4. How to trigger the "Inbound IDOC Process" from JAVA software to SAP and how to store the data in SAP
Experts, please give your feedback in terms of reply or by sending the step by step process to fulfill this client requirement.
Thanks for your cooperation.
Regards,
Ramesh

Maybe too many open questions in the same document.
Maybe you should repost a more specific question in a technical forum.
This looks like a small project where you already know what you want, maybe you should contract a technical specialist so he proceeds to the implementation!

Secure the file/data transfer between XI and any third-party system

Hi All,,
I would like to use to "secure" SSH on OS Level the file/data transfer between XI and any third-party system Run OS Command before processing and OS command After processing. right now my XI server installed on iSeries OS.
with ISeries we can't call the Unix commands hope we need to go for AS400 (CL) Programming. If we created the AS400 programm how i can call that in XI.
If any one have idea pls let me know weather it will work or not.
Thanks in adavance.
Venkat

Hi,
Thanks for your reply.
I have red some blogs like /people/krishna.moorthyp/blog/2007/07/31/sftp-vs-ftps-in-sap-pi to call the Unix Shell script in XI.
But as i know in iSeries OS we can write the shell script we need to go for AS400 programe. If we go with AS400 how we need to call that programe and it will work or not i am not sure there i need some help please.
Thanks,

Data transfer between OSX 10.9 and WIN 7 stops

Hello,
Unfortunately, I have a problem with the data sharing through SMB.
I can connect easily to my Mac and see shared folders or data. But in attempting to copy files from Mac to Win 7 PC there is an error. The data transfer is terminated after a while. The file used in the test is an MKV with the size of 1.34 GB.
The Mac is accessed from a Win 7 PC with administrator privileges. The systems are connected via Wi-Fi 802.11 n.
The exchange of data between OSX in use of SMB or AFP works without any problems.
Maybe someone has a solution or a tip for me.

Data Transfer Between HR and Erec

Hi all,
We are using having 2 backend systems 1 for HR other than Erec and another one for erec.
Now we have setup the ALE data transfer using Message type HRMD_ABA.
In erec we have only ERECRUIT Component deployed in backend,no EA HR or SAP HR component deployed.
MEaning no PA* tables.
Now when Transfer personnel number(HR!001-A008 with Position) to erec box,it says no pernr exist.
Howver i cannot tranfer the pernr from ECC to Erec as we dont have PA* tables in Erec.
Can you share me the object types that are transferred from ECC to EREc and EREC and ECC.
What are the components to be deployed in backend Erec box.
In Portal for requistions application which should backend(System Object) and for recruiter and recruitment admin applications which should be the backend system(System Object).
Thanks,
Nachy

Hi ,
1) First get your users created with roles in your Erec system
Example recruiter ,Manager ,Recruitment Admin
2) Get your Structure created in your HR back end system .
3)Make sure you maintain your basic Infotypes with 0105 miantained (System user name /Email id )
Assign the user to 0105 subtype 0001
4)ALE that you have setup first move Org structure moved
next move the person (Pers no ) .
ALE chose the insert mode and goto WE10 if yoru IDOCS are clean without errors .
Make sure all the personal data including address ,postal code is all maintained .
Let me knwo if it helps

Low data transfer between my iMac & Time Capsule

Hello,
I have just purchased 1GB Time Capsule yesterday to get a back-up of my iMac HDD, and also to use it as an external HDD. I was much interested by the wireless functions.
After the installation, Time Machine started to save a back-up of my HDD (more than 200GB). But after one full night, only 7GB out of 220GB was transfered wireless.
With a so low data transfer, it will take 20 days for the full back-up.
Is it normal ?
Do I have to make the first back-up though ethernet (wired) ?
I am working on big video files (xx GB), so I really need to increase the speed of data transfer. Is there someting to change in the settings ?
Thank you for your help, it will be highly appreciated...

Vendor Master Data Transfer Between the Clients

Hello Everyone,
I want to transfer Vendor master data between the clients, can any one help me in this Please?
I don't want to use LSMW, Is there any other method by which i can copy the vendor between the clients or i have to do it manually?
Please Help ASAP
Thanks
M

Hi,
You have to do necessary setting for ALE and IDOC will get generated and data will get transfer based on the Program Schedule in Bacground.
You can schedule program in bacground as per your requirement of IDOC transfer and data generation from One Client to other. [i.e. end of the day, Hourly, monthly etc.]

Most efficient data transfer between RT and FPGA

This post is related to THIS post about DMA overhead.
I am currently investigating themost efficient way to transfer a set of variables to a FPGA target for out application. We have been using DMA FIFOs for communications in both directions (to and from FPGA) but I'm recently questioning whether this is the most efficient approach.
Our application must communicate several parameters (around 120 different variables in total) to the FPGA. Approximately 16 of these are critical meaning that they must be sent every iteration of our RT control loop. The others are also important but can be sent at a slightly slower rate without jeopardising the integrity of our system. Until now we have sent these 16 critical parameters plus ONE non-critical parameter over a DMA to the FPGA card. Each 32-bit value sent incorporates an ID which allows the FPGA to demultiplex to the appropriate global variables on the FPGA. Thus over time (we run a 20kHz control loop on the RT system - we have a complete set of paramaters sent @ approx. 200Hz). The DMA transfers are currently a relatively large factor in limiting the execution speed of our RT loop. Of the 50us available per time-slot running at 20kHz approximately 12-20us of these are the DMA transfers to and from the FPGA target. Our FPGA loop is running at 8MHz.
According to NI the most efficient way to transfer data to a FPGA target is via DMA. While this may in general be true, I have found that for SMALL amounts of data, DMA is not terribly efficient in terms of speed. Below is a screenshot of a benchmark program I have been using to test the efficiency of different types of transfer to the FPGA. In the test I create a 32MB data set (Except for the FXP values which are only present for comparison - they have no pertinence to this issue at the moment) which is sent to the FPGA over DMA in differing sized blocks (with the number of DMA writes times the array size being constant). We thus move from a single really large DMA transfer to a multitude of extremely small transfers and monitor the time taken for each mode and data type. The FPGA sends a response to the DMA transfers so that we can be sure that when reading the response DMA that ALL of the data has actually arrived on the FPGA target and is not simply buffered by the system.
We see that the minimum round-time for the DMA Write and subsequent DMA read for confirmation is approximately 30us. When sending less than 800 Bytes, this time is essentially constant per packet. Only when we start sending more than 800 Bytes at a time do we see an increase in the time taken per packet. A packet of 1 Byte and a packet of 800 Bytes take approxiamtely the SAME time to transfer. Our application is sending 64 Bytes of critical information to the FPGA target each time meaning that we are clearly in the "less efficient" region of DMA transfers.
If we compare the times taken when communication over FP controls we see that irrespective of how many controls we write at a time, the overall throughput is constant with a timing of 2.7us for 80 Bytes. For a small dedicated set of parameters, the usage of front panel controls seems to be significantly faster than sending per DMA. Once we need to send more than 800 Bytes, the DMA starts to become rapidly more efficient.
Say hello to my little friend.
RFC 2323 FHE-Compliant

So to continue:
For small data sets the usage of FP controls may be faster than DMAs. OK. But we're always told that each and every FP control takes up resources, so how much more expensive is the varsion with FP controls over the DMA.
According to the resource usage guide for the card I'm using (HERE) the following is true:
DMA (1023 Elements, I32, no Arbitration) : 604 Flip-Flops 733 LUT 1 Block RAM
1x I32 FP Control: 52 Flip-Flops 32 LUTs 0 Block RAM
So the comparison would seem to yield the following result (for 16 elements).
DMA : 604 FLip-Flops 733 LUT 1 Block RAM
FP : 832 FLip-Flops 512 LUT 0 Block RAM
We require more FLip-Flops, less LUTs and no Block RAM. It's a swings and roundabouts scenario. Depending on which resources are actually limited on the target, one version or the other may be preferred.
However, upon thinking further I realised something else. When we use the DMA, it is purely a communications channel. Upon arrival, we unpack the values and store them into global variables in order to make the values available within the FPGA program. We also multiplex other values in the DMA so we can't simply arrange the code to be fed directly from the DMA which would negate the need for the globals at all. The FP controls, however, ARE already persistent data storage values and assuming we pass the values along a wire into subVIs, we don't need additional globals in this scenario. So the burning question is "How expensive are globals?". The PDF linked to above does not explicitly mention the difference in cost between FP controls and globals so I'll have to assume they're similar. This of course massively changes the conclusion arrived to earlier.
The comparison now becomes:
DMA + Globals : 1436 Flip-Flops 1245 LUTs 1 Block RAM
FP : 832 FLip-Flops 512 LUT 0 Block RAM
This seems very surprising to me. I'm suspiscious of my own conclusion here. Can someone with more knowledge of the resource requirements differences between Globals and FP controls weigh in? If this is really the case, we need to re-think our approach to communications between RT and FPGA to most likely employ a hybrid approach.
Shane.

Data Transfer between BW and BO

I have two servers in different networks, there is a firewall between the two networks.One get through to the Internet, and the other one get through to the Enterprise Intranet. BusinessObjects Enterprise XI 3.1 SP3 is setup in one server which can get through to the Internet,and Busniess Warehouse is setup on another server which can only get through to the Enterprise ntranet. My question is how to deploy BusinessObjects, so that we can transfer the data in BW to BO.

Help required please on data transfer between DAW's

Are there any Logic user/s who have moved DAW from Cakewalk to Logic and have transferred
song data between the two applications? I have tried using OMF but my songs dont line up and go out of synch. Am I using the right file format or is there a better way to do this please?

Disappointed about the lack of folks who, as per your requirement, converted from Cakewalk to Logic just in time so they could read your post and answer to it ? That would be a bit much, even for Earth Coincidence Control ECCO.
Converting from one platform to another is one thing, converting from one sequencer to another is another thing, transferring audio is a third, transferring MIDI is a fourth and finally transferring all the other stuff is a fifth chapter altogether.
Switching platforms is a relatively problem-free endeavour if you make sure there are no special characters ()"!§$%&/*+'#_-:.;,ÄÖÜäöü etc. in any of your file names. If you happen to use +Guitar(take 5):from 5'12"/ 100% wet+ as a file name, you are in trouble. Guaranteed.
Also make sure you keep file names under 32 characters. Oh, and don't create 32-bit audio files, as these won't work in Logic.
Logic Projects don't play in Cakewalk and vice versa, as you found out.There is no conversion standard to transfer sessions between DAWs, so you have to make do with what is there and take care of the rest yourself.
Audio is best converted into one long Region per track, and all Regions must begin at the exact same spot, like 1.1.1.1. This way it takes 15 seconds max to line up all your audio tracks in the new software.
MIDI can be saved as one or several SMF (standard MIDI File). Each can carry 16 MIDI channels + Tempo information.
There is no way to transfer all what's left, that is, signature changes, take folders, playlists, audio routings, audio plugins and their settings, markers, text notes, MIDI plugins, etc. So you really need to invent a good working scheme with a writing pad and a lot of screenshots. And quite some concentration and endurance.
Good Luck

Data transfer between 2 table views

Dear Gurus
Here is my scenario.
I need to transfer data between 2 table views (Both these table views are having only column). These 2 tables are present in separate views (under same viewset).
Now initially I need to display some data in one of the tables when I display the screen for the first time (this I was able to achieve). Now if I double-click on any row of this table, I need to move the data present in that particular row to a different table present in the same screen.
Here is what I have achieved.
1) When I click on any row, I was able to capture the row index and the corresponding data in that row.
I put some code in the method EH_ONSELECT (present in the event handler) to get this working.
Now my question is
How can I move this captured data into a different table view?
I tried investigating on some of the methods such as do_prepare_output. But I am left with no clue on what coding needs to be done here.
Any help will be greatly appreciated.
Thanks
Raj

Hi Raj,
You can write the code in methods like DO_PREPARE_OUTPUT, but need to take adequate care of perfrormance as this method gets triggered for all server events.
If you can identify any other method on the second view at an instance when you select rows on view1..
that too is fine.
You can get the selected entries from a context node collection wrapper method...
DATA: lr_marked_line TYPE REF TO if_bol_bo_col.
* Get the lines selected by the user
lr_marked_line = me->typed_context->productcategory->collection_wrapper->get_marked( ).
You can do a work around this way too...create an internal table attribute in the IMPL class of Custom Controller...Update it with the selceted rows in view1.
Populate view2 with the values in this table by accessing them from Custom Controller.
Code can be in DO_PREPARE_OUTPUT or some method that triggers at the point you select values in first row.

Data Transfer between AS400(Linux) and Oracle(Windows Server)

Hi,
We have AS400 system which resides on Linux architecture.
We want to transfer millions of records from AS400 to Oracle which resides on Windows server.
We think to build Odbc connection on windows machine and accessing to AS400 data from this connection.
But I am not sure the performance of this approach.
I would be glad if you share your experiences.
Regards & Thanks

Hi,
ODBC is generally pretty slow in my experience - your alternatives are probably one of the following
1) use odbc maybe with heterogeneous services on top (this allows you to have a database link directly from oracle to db2)
2) use a transparent gateway - similar to 1) but has more functionality and will have a licence cost
3) write some c/java program to do it
4) dump the data to a flat file, transfer to windows, sqlldr that file in
It all comes down to how good the performance needs to be (ODBC may be good enough) and how much effort needs to be put i to other approaches.
I suggest you just give odbc a try, if it looks like its not up to the job then consider alternatives. In the past we've used option 4 for this kind of thing but it is very dependent on the environment you are running in (amount/type of data, speed of network etc).

Harry
