Requirement for multiple MessageListeners for ServerSessionPool

Folks,
On page 83 of the JMS Spec, section 8.2, the following is present:
---- spec ----
o Application - its role is to define a subscription with a destination and optionally a message selector and provide a single-threaded MessageListener class to consume its messages. An application server will construct multiple objects of this class to concurrently consumer messages.
---- spec ----
This seems to be saying that in the Application Server Facilities framework, a SEPARATE MessageListener implementing class will be needed for each concurrently processed message received by the ConnectionConsumer. I find this very strange. I can't see why a single thread safe MessageListener could not be used.

If you want all the messages to be consumed sequentially in a single thread, you should configure the app server that way: use a ServerSessionPool with a single ServerSession.

  • Can I use Signal Express for multiple customers for only the one time $699?

    How do I go about distributing Signal Expresss applications to multiple customers?

    Hi Nutter,
    Unlike LabVIEW, Signal Express doesn’t have any file distribution capabilities.  If your application uses only basic features, you could install the free LE version of Signal Express on as many computers as necessary.  If you need the full capabilities of Signal Express, however, you would need to purchase a license for each customer.
    An alternative to paying for Signal Express for each customer deployment would be to generate LabVIEW code from the Signal Express project and create an executable.  This process is described in the Knowledge Base articles Generate LabVIEW VIs from Signal Express and Deploying VIs generated in Signal Express.  Note that this method requires that you have LabVIEW installed on your development computer with Application Builder capabilities.

  • Restrict PO creation for multiple plants for same company code

    Hi Gurus,
    We want to restrict PO creation for multiple plants in the same company code. Based on Standard SAP settings for Purchasing organization assignment with multiple Plant and multiple Plant assignment with single company code, this is happening. Is there a way that we can restrict by doing some customization change.
    Any thoughts or ideas will be highly appreciating.
    Thanks and Best regards,
    Karun Kumar

    Hi,
    Said functionality is not available in SAP standard.
    To avoid the same ,i can suggest implement release strategy for PO,and then higher authority / commercial team can check created PO,if multiple plants available in single po then they have the option of rejection for the same.
    Or else check BADI-ME_PROCESS_PO_CUST,take the help from abapor and apply the restriction to select multiple plant in PO.
    Hope this will resolve your query,
    Thanks & Regards,

  • ITunes for multiple accounts for Windows XP

    I am the admin on my PC with Windows XP. I have iTunes installed under my account. I just got my wife an Nano.

    Can I install another iTunes under her account, move the music to a shared folder, and have both iTunes use that shared library? If not, can you please share the best approach.
    you shouldn't have to install itunes in her account. she should have it already in her account if it has been installed on yours.

  • Can we set "IN PROCESSu201D status for multiple users for a single workitem?

    Hi,
    As per my client current scenario every work item will be sent to 3 useru2019s (One is the supervisor of the other two users). If any one of the user executes the work item it will automatically call a Ztransaction and displays the screen. When the user without taking any action, he presses the BACK button (in Ztransaction) and comes out of the transaction. Then the workitems for the rest of the users will disappear from there inboxes.
    But my client requirement is such that, whenever the user click on back button the workitem should be "IN PROCESS" status for two users(One is the supervisor and one who executes the workitem) out of  3 users possessing the workitems.
    Please provide me any advice to the above requirement.
    Thanks in advance,
    Ranganadh

    I think this can be done either by putting a check whether the user does anything. If he does a flag should be set which can be used in the Codition Tab of the Activity step that will prevent the workitem from completion.
    Thanks

  • Table data getting locked for multiple user for a Z-table updation after EH4 to EHP6 Upgrade

    Hi,
    We have one new upgraded system at EHP6, earlier system was at EH4 where multiple user can Run one Z  T-code and can edit the entries for the Z-table.
    This Z-Tcode is calling SM30 internally for updating the Z-Table.
    Now in the upgraded system, when one user is into the transation code, and other user runs that T-code, systems throws a POP-UP mesg saying that the data is locked and can be displayed only(can not be edited).
    I have debugged the code in both the environment and found that there is one statement Call C_ENQUEUE ID < > field. for which the Sy_Subrc is coming as 2 in the upgraded system which is causing the issue, where as the sy-subrc is 0 in the system at EH4 level.
    Can any body tell me why this Z-tcode is not allowing to be accessed by multiple user at same time for Editing(updating the table) .
    Regards,
    Archana Jha

    Hi,
    When you create the lock object you can define the keys.
    and then you can use those in the ENQUEUE function.

  • CSS11501 - URL Redirect for Multiple Servers For Both Ports 80 & 443

    Can the CSS rules be configured such that it can be used to direct requests to different Web servers based upon,
    URL path? 
    For Both Ports 80 & 443/HTTPS (with SSL Certificate running on the back-end servers)
    For example:
    http://app.ti.com/path1/file.html goes to Web servers A & B -> old servers
    https://app.ti.com/path1/file.html goes to Web servers A & B -> "
    http://app.ti.com/path2/file.html goes to Web servers C & D -> new servers
    https://app.ti.com/path2/file.html goes to Web servers C & D -> "
    We're trying to understand what are plans are for a phased migration from old site to new site, and if it requires new URLs ???
    Fort port 443, since the CSS is load balancing SSL encrypted traffic, is the means that the CSS can’t look at URL thus this is not possible?
    Please help, thanks.

    Hi Martin,
    1) Clients are using http://domain/, thus I need to define url "//domain/.." as you have stated.
    2) I'm still waiting for the "actual" URL paths from the application team in order to decide which method to use - Regexp vs URLQ definition - to begin testing.
    I know I have limited memory resource (as listed below) & will try not to make it complicated:

  • How to trigger data recording to a text file for multiple channels for a certain voltage threshold?

    I am working with 6 channels, from each of which I am obtaining voltage values ranging from 0.6-6 V.  I am using the DAQ Assistant to acquire and write the data to a text file.  However, I only want the data to be written to the text file when the difference in voltage (DeltaV) from one data point to another is greater than or equal to 0.04 V.  I am acquiring the data at a sampling rate of 64 Hz.  Any ideas on how to accomplish this?  I have attached my current VI.

    Your code does not do what you describe above..
    I just want to make sure I understand your request...
    Let's say you have the following signal:
    0.00
    0.01
    0.00
    0.03
    0.02
    0.01
    0.03
    0.04
    0.07
    0.05
    0.08
    0.03  < delta greater than 0.04, so start recording
    0.11
    0.21
    0.45
    0.93
    2.87
    5.85
    5.86 < delta less than 0.04, so stop recording
    5.87
    5.89
    6.00  < delta greater than 0.04, so start recording
    5.85
    5.86  < delta less than 0.04, so stop recording
    etc..
    Is the above what you are describing?  
    Right now, your code does this:
    0.00
    0.01
    0.00
    0.03
    0.02
    0.01

    0.11
    0.21
    0.45
    0.93
    2.87 < threshold greater than 1 so reset timer
    5.85 < threshold greater than 1 so reset timer
    5.86 < threshold greater than 1 so reset timer
    5.87 < threshold greater than 1 so reset timer
    5.89 < threshold greater than 1 so reset timer
    6.00  < threshold greater than 1 so reset timer
    5.85 < threshold greater than 1 so reset timer
    5.86  < threshold greater than 1 so reset timer
    4.35 < threshold greater than 1 so reset timer
    2.21 < threshold greater than 1 so reset timer
    1.09 < threshold greater than 1 so reset timer
    0.98 
    However, you did not provide a set start time  to the Elapse Time (I never use Express VI's so I'm not sure what will happen..) However, something does not appear correct with the logic.  I'd have to check.

    at the moment, I am the only one with pages and numbers

    Mark,
    You should all be able to use iWork apps, and most other apps, I would think. My guess is that somehow your iWork apps were moved out of the main Applications folder. If your Numbers and Pages apps are not in Macintosh HD > Applications > iWork '09 they won't get properly updated as revisions are released via Software Update, and they may not  be available to other users.

  • Single ERS Invoice for multiple POs with different GS and same IP

    Dear All,
    I have a Requirement as per the below scenario:
    We need to have single invoice created using ERS (MRRL) functionality in the below scenario:
    Two POs created with different Partner function GS (goods supplier) and same IP (Invoice party partner function).
    Ex:
    GS IP PO GR ERS
    vendor1 10001 4500001 500001 Yes ( GR-IV-Yes, GR done- Yes, same payment terms - 001)
    vendor2 10001 4500002 500002 Yes ( GR-IV-Yes, GR done- Yes, same payment terms - 001)
    When I run ERS for last 1 week (GR) and select the option (Doc selection – per IP or other criteria like GRs posted in last one week) , system should create 1 invoice document. Standard SAP posts 2 documents for each GS.
    I have tried using 2 user exits for MRRL, but none of them work for this functionality.
    Thanks,

    Hi,
    Go for  MIRO without MRRL.
    Instead ERS, you can post single  Invoice(MIRO) for multiple POs  for one vendor.
    OR
    Check with Technical consultant and go for development to have single ERS output for multiple ERS invoice documents for single vendor.

    Dear Mujubur,
    It is generic feature of a business that price is changed for various reasons. So excise accounting is adjusted corresponding it.
    What you do, please create a debit memo request which is a sale order type document by VA01 with reference of all commercial inovices against which you want to create the single supplementory invoice. Then create a debit memo which is a bimming document by VF01 with reference of that debit memo reuest and do the release to accounting.
        Then part A/C will be debited and all other corresponding accounts with Excise provision A/C will be creadited. Now create a billing type as proforma invoice (Bill category U) in configuration and mainatin the copy control from debit memo document type.
    It is better to do the configuration first. Then create the proforma invoice with reference of that debit memo. It will be like a image document of the debit memo. Then create excise invoice by J1IIN with refernce of that proforma invoice with different number series if you want tom maintain. Then excise account will take place -  Ex provision Dr ,  ED payable Cr. That Excise document is  your desired supplementory excise invoice. It will also come in the scope of excise utilisation in J2IUN. The proforma invoice is to be created other wise excise document with transaction type DLFC will not vecreated as it creates only from proforma inovice , not from any other type of billing document.
        Don't go for Excise JV. Apparemntly it is seemed that will be easier but your accounting will be wrong and there will be no track of data which will lead a problem for long run.
    Please do it.  If more help required then inform. I have implemedted the same process.
    Hope this will serve your purpose.

  • Maintain multiple address for vendor

    User purchase article from vendor A at addess#1 but returned article back to vendor A via address#2. Vendor has 2 different departments handling delivery and returns.
    How can I configure 2 adddress for the same vendor code?
    If I had to used a partner function, what suggested partner function should I used?
    My PO order entry currently only accept vendor code.
    Suppose I need to add in a partner, like sold-to and ship-to in SD, is there a way to configure the screen?
    Where do I do it.
    Thanks
    bye

    Hi Colin,
    What is the bussiness reason for multiple addresses for the same vendor?
    If the vendor maintains several different physical locations at different addresses, then they should be created as different vendor master records. Then, if they all use the same payment office, they can be partnered to the same invoicing vendor.
    If you need to add a seperate address for the supplier location, payment location, billing location, etc, then you must create each of them using the correct account group and use partnering to tie them all together.
    Also, there is a way to maintain multiple addresses for the same vendor - but this is used for maintaining different international versions of the same address. (See the international button) - which requires some configuration in central address management.
    Or,
    Go for one-time-vendor concept else it is not possible .
    Also,
    Partner function can be used to maintain different address.
    This is the advantage of keeping the partner function in vendor account groups.
    You create different vendor codes for different addresses and assign the same.
    Regards,
    Rahul.
