BW 3.5 and 7.0 in parallel

Hi
We have a BW 3.5 system which is connected to ECC 5.0 OLTP. We are going for a new implementation of BI 7.0 system, while continuing to use the BW 3.5 system for at least a year . So after the implementation we would have one source system and two target BW system ( 3.5 and 7.0 ) .
What are the precautions we need to take before going live with BI 7.0 system?
Any experiences shared / any useful notes we can refer would be much appreciated
Thanks
Arun

10) diff between 3.x info spoke and 7.0 I spoke ?
InfoSpokes are no longer used with BI 7.0. They can be used with 3.x emulated Data Sources;
use open hub destination  instead.
BI objects such as InfoCubes, DataStore objects, MultiProviders or InfoObjects (attributes or texts) can function as open hub data sources.
11). if I have routine in 3.x how do u migrate in to 7.0?
Automatically there is no tool to convert the 3.x routines to routines in transformations.Manually you have to create transformation with the help fof ABAP programming.
12) what is rule group and semantic group
Semantic group is a feature in the DTP (data transfer process) that is used define a key for evaluation.
The key determines which records should be detained when processing. For example, if you define "order number" and line as the key, if you have one errorenous record with an order number 123456 line 7, then any other records received in that same request or subsequent requests with order number 123456 line 7 will also be detained.
Think of semantic groups as the key of the error stack - it's a data quality feature really.
A rule group is a group of transformation rules. It contains one transformation rule for each key field of the target. A transformation can contain multiple rule groups.
Rule groups allow you to combine various rules. This means that for a characteristic, you can create different rules for different key figures.

  • Dock and UI freeze with Parallels on 10.6.8

    Hi,
    I recently updated my MacBook Pro 17" to 10.6.8, with no problems. Fabulous machine.
    Yesterday, I installed Windows 7 into Parallels (yeah, I know. Long story) and then watched with mounting frustration and despair as my lovely friendly machine ground to a halt. Literally.
    Current situation
    When I start up the machine up, the OS boots up fine (or appears to). Then the Dock disappears. Or flashes briefly, then disappears. Or appears but is completely unresponsive. Then, shortly after, the entire UI becomes unresponsive. The mouse pointer moves, but that's about it. No keyboard control. No interactivity. Re-starting the hardware solves nothing. Re-starting in safe mode solves nothing. I've unplugged all external USB devices and the Time Capsule. No joy.
    Cause?
    I suspect that it is Parallels. Or rather a particular build of Parallels under 10.6.8, with one particular option checked, i.e. "Show windows applications in Dock". Why do I think this? Check out http://kb.parallels.com/en/111541
    Now, what I'm trying to figure out is what the feck I do to fix this and roll back the Parallels install when I have no significant UI control for more than a few seconds after login... deep sigh. 
    Any good suggestions most welcome.

    Parallels has a solution/fix for the problem, or you can try the just released version.
    See http://reviews.cnet.com/8301-13727_7-20074173-263/dock-using-100-cpu-after-os-x- 10.6.8-update-for-parallels-6-users/.
    Or you can try this:
    Navigate to the /Users/yourname/Library/Preferences/ folder and delete these 2 files:
    com.apple.dock.plist
    com.apple.dock.db.plist
    Restart.

  • Adpatch: Error running SQL and EXEC commands in parallel

  • InfoPack processing (PSA and data targets in parallel) data and lock issues

    Good morning,
    We are on BW 3.5 and contemplating changing our InfoPackages from option 1 (PSA then data targets) to option 2 (PSA and data targets in parallel) for performance reasons (test have shown a gain of 50% in load time compared to using option 1).
    Issues have been raised that using option 2 may lead to data consistency and lock issues especially for SD infosources where we are dealing with multiple daily status changes for same document that need to be read in a specific order.
    From what I have read, such issues were possible in BW 2.x e.g. OSS Note 384023 and 364577. However, I am under the impression that the issues may have been resolved in BW 3.x and that it is "safe" to use option 2 (PSA and data targets in parallel).
    Would really appreciate if you could please share your experience when using processing option 2 (PSA // DT) especially in a BW 3.xx system.
    Thank you in advance,
    Catherine

    Hi Amit,
    The help text (vers. 3.5) for this method of loading says simply -
    "A process is started to write the data from this data packet into the PSA for each data package. If the data is successfully updated in the PSA, a second parallel process is started. In this process, the transfer rules are used for the package data records, data is adopted by the communication structure, and it is finally written to the data targets. Posting of the data occurs in parallel by packet.
    This method is used to update data into the PSA and the data targets with a high level of performance. The BW system receives the data from the source system, writes it to the PSA, and starts the update immediately and in parallel into the corresponding data target"
    Not sure where you got your description from, but is not explained well and confusing.
    Regards,
    Ken

    Already made. In the meantime one more report in VMTN
    about the same issue with parallels.
    Henri
    Can you link to the parallels thread?
    I can reliably reproduce a kernel panic in 10.4.8 by ejecting a volume mounted from a host system (default afp mount) that is either of two macintel systems (mini & mbp).
    Problem started when I installed Fusion, went away when I de-installed. Both systems also have Parallels (latest build but one) installed.
    The workaround of unloading the networking kexts makes me nervous -- sooner or later I'll forget, and then KABLOOEY!

  • Measuremen​t, visualizat​ion and saving data in parallel: Performanc​e question

    Hello,
    I have written an application with 3 loops running in parallel.
    The first loop does only measure and analyze measurement values from a DAQmx device (3 analog input signals from 3 sensors with 1000 Hz).
    The second loop does only do the visualization with a graph per sensor continously. The data will be sent from the first loop through a queue.
    The third loop only saves the data to a file after a measurement has finished. The data will be sent at the end of a measurement from the first loop, too.
    There are 3 measurements running asynchronous.
    That means it could be that only one sensor will be read, but it also could be that 3 sensors will be read. The duration of each measurement phase and the beginning/end is asynchronous.
    Now I have the following problem:
    Measurement 1 starts
    A short time later measurement 2 starts
    Measurement 2 will end, the measurement values will be saved into a binary file
    Measurement 1 is still running but the visualization of measurement 1 stops for about 1 second during the saving process. After the data is saved, the visualization runs normally again (no data is lost because of the queue).
    Why does tha graph stop its visualization during the saving process (I have a dual core cpu)?
    How can I do this in a way, the user does not see any lags?
    It all works fine but the "interrups" look very unprofessional.
    Regards
    Matthias

    Hello,
    I'm using the producer/consumer pattern.
    Maybe it could be, that the dll calls I'm using for saving will interrupt the whole program: http://lavag.org/files/file/212-sqlite-labview/
    When I use the LabVIEW File-I/O vis all is fine. But when I use these database vis my application will lag.
    Any ideas why this is so? Could it be that the dll calls freeze the application during the saving process (LabVIEW 2011)?
    Here are thze dll settings:

  • Copy and paste in Captivate parallels

    I am running Captivate in Windows via Parallels. My Photoshop
    is installed on the Mac side of my computer. I am having trouble
    copying backgrounds from Captivate and pasting into Photoshop to
    edit them. Does anyone know of a work around other than copying
    from Captivate, sending the image through e-mail to the Mac side of
    my computer, downloading the image and opening it photoshop, saving
    the image to a shared folder and importing the corrected image into
    Captivate as a background.
    When I was running Captivate off of a pc i could just copy
    from Captivate and paste right into Photoshop. HELP ME!! Any
    suggestions?

    Hi KatyMcKee
    I would think the answer would lie in saving the image to
    your hard drive and bypassing all the E-Mail action. Then you just
    bounce over to Photoshop and open it up off the hard drive.
    Cheers... Rick

  • 2GB enough to run Windows 7 and Snow Leopard via Parallels?

    I'm debating using Parallels to run Windows 7 but wasn't sure if 2GB would be enough RAM or would I need to upgrade to 4GB?

    I think 1GB is the minimum. I had the Windows 7 Compatibility Tool check out my old lappy to see if it could handle 7, and it said that my ram could handle it HOWEVER it recommended that I upgrade to 2GB

  • External and onboard sampling in parallel

    Hello everybody,
    I made a simple example to demonstrate what I am trying to achieve but my problem can be summarized with one question: Is it possible to have in parallel one task that samples channel AI0 with the onboard clock and another task that samples channel AI1 with external clock source?
    In my application I have 
    1) One task measuring lets say pressure or temperature at one channel with the onboard clock
    2) One task calculating the frequency of revolutions of incremental sensor (IRC)
    3) One task sampling signal from laser probes using the IRC signal as external source
    They are supposed to run in parallel
    2+3 works perfect but when I add also 1 I get Error -50103 occurred at DAQmx Start Task.vi:1, The specified resource is reserved. The operation could not be completed as specified. Also 1+2 works perfect together. Program attached - it's just fast example.
    Thanks a lot

    Trying to create more than one task for AI the same time result in the encountered error message....This is because AI can only have a single sample clock source. Due to device access, this is a prerequisite for a single device. Having more than one DAQ device will enable you to define two different clocks for the two devices.

  • I want to see PP stock in dry and wet scenarios in parallel.

    I am using PP in a coke plant. The stock is uploaded as wet i.e. ( x tons of coke + y tons of moisture) through 561 movement. This entire stock is then taken up through a stock transfer order process in SD and a goods issue posted. However, my management would also like to see in parallel, the x ton (dry stock) separately also without affecting the MM reports like MMBE. They would also want to see this dry qty diminished when PGI of the wet stock also happens in the same proportion in which they have been PGIed.
    Is there any way in PP to achieve this objective?

    Hi Partha,
    As I perceive, at the moment, you are using only one part number that represents the FG/SFG (mixture of coke & moisture). You create a STO and book a GI against the STO.
    In terms of the PP modul my suggestion would be as following:
    - you should maintain stock for all ingredients (components) >> this would mean the maintanance of separate part number of each component
    - you should maintain BOM for your SFG/FG
    - and you should maintain other suitable master data (work center, routing)
    In this case the process would be to issue a PrdOrd for your FG/SFG. During the confirmation (booking against PrdOrd) you would get your FG/SFG by mvt 101 and consume your components via mvt 261.
    After that you could deliver your SFG/FG to its destination (e.g. via delivery, STO).
    Please make your question clear it is very difficult to understand the process described by you and it's not toatally clear what you want exactly.
    Thanks,

  • Linear and Binary Searching of Parallel Arrays

    I'm an AP student who used the "Fundamentals of Java" by Lambert/Osborne 3rd Edition. This text book has code that doesn't match anything else I've found in other how-to's, guides, or teach yourself books. Not even online can I find code that matches up with the format used in this book!
    I've got an assignment that wants me to read in a 4 digit account number of N number of customers, places them in two parallel arrays. Data found in two separate txt files. Create a prompt that ask's for customer's account number then displays account balance. Same program for both linear and binary search methods (2 programs).
    I know the search method and how to read the files with a scanner. It is the body of the program that is stumping me. How to call and search the arrays themselves. Any help would be great.

    First of all, you have posted this question in the wrong place. Please post these kinds of general questions in the New to Java forum.
    Second, if you're in an AP class, don't you have a teacher you can ask?
    But anyway, here's the idea
    For a linear search, you go thru the array element by element, and on each element you call equals(x) to see if that element is equal to what you're searching for (note that primitives use == rather than equals)
    For binary search, note first of all that your data MUST BE COMPARABLE (primative or implement the comparable interface) and MUST BE SORTED.
    Then what you can do if go to the middle of the list, and if what you are searching for is less than that element, go to the middle of the first half of the list (if it's greater, go the the middle of the upper half of the list) and keep breaking the list in half until you've found the element or you know its not there.

  • Need quick help, please!!! How do I scan the counter and analog channel in parallel, synchronized?

    Hi,
    I'm using LabView6.1 and a PCI6014 DAQ card.
    I have to scan simultaneously an analog channel and the counter on the card. My project requires me to measure in parallel a force (a voltage on an analog channel) in correspondence to a distance (measured with a counter) and I have to display a force-distance graph.
    So, can someone please tell me how can I program the counter and an analog channel to take 1000 measurements in parallel, and then, by reading the buffers to have two sets of corresponding measurements?
    I've tried some things and I've got only an error message, that says that there is no free DMA channel available (the error comes from configuring
    the analog channel). I attached one of these programs that gives this error, maybe somebody can tell me what I do wrong.
    If somebody could send me an example (in LabView6, I have no 7 :-( ), I would be grateful.
    Thank you,

    Hi pixooxiq,
    unfortunately, your Card has only one DMA-Channel.
    If you want to use two Channels simutaneously, you have to tell one of them to use an Interrupt instead.
    This option can be set with the "Set DAQ Device Information.VI"
    Just see the Bitmap, I've attached.
    Perhaps, you now get Performance-problems, cause the IRQ does not directly write the Data but involves the CPU. In this case the only possibillity is to use an other card with more than 1 DMA-Channel...

  • AE 5.1 and 5.2 - Configuring parallel workflows for "Delete" Request type

    Has anyone configured parallel workflows for the "Delete" Request type?  I want to configure 1 for SAP and 1 for non-SAP applications, but have been unable to do it successfully. 
    The initiators I have created that do not work are:
    1 - SAP initiator:
    SAP application with "OR" condition
    Request Type = Delete with  "AND" condition
    2 - Non-SAP initiator:
    Non SAP application 1 with "OR" condition
    Non SAP application 2 with "OR" condition
    Non SAP application 3 with "OR" condition
    Request Type = Delete with  "AND" condition
    When I create a request to Delete a user with SAP app and Non SAP app I get the error:  "Error in creating request. Multiple Initiators, [NON SAP DELETE, SAP DELETE] Found."
    Based on what I am reading on p. 58 of the AE52ConfigGuide.pdf, this should be possible to do.  Does anyone have any suggestions?

    This is my understanding.,
    A request cannot have more than one initiator. You cannot trigger multiple initiators for one single request. In your case both attributes SAP & Non SAP application are given with OR condition which makes both the initiators alike. As mentioned in the documentation the request for deletion can be made to happen in both SAP & Non SAP application by having forked path (for this the initiator should be OR Application SAP OR Non SAP Application AND Request Type Delete). Given the other option then it should have different initiator for SAP and Non SAP applications by giving them with AND condition.
