Any plan to support tightly coupled transactions across domains?

Hello,
is there any plan to support tightly coupled XA transactions across domains?
Our application has a few global transactions that span multiple domains. One domain updates a record in the Oracle DB. Later on in the same transaction the second domain retrieves the same record. But because of the loose coupling, the second domain cannot see the changes made by the first domain.
Thanks...
Roger
PS: In some cases the second domain is actually a WLS domain. Because the loose coupling is a limitation of the Tuxedo Domain Gateway and WTC uses GWTDOMAIN, one could assume that once Tuxedo supports tightly coupled transactions across domains, WTC would also support it.

Hi Roger,
We don't have plans at the moment to solve this problem, although if it is a major problem for you, I suggest you contact Oracle support and ask them to enter an enhancement request. In general most customer have separate databases for each domain or application, thereby not normally running into this problem. Also, changing this in Tuxedo doesn't necessarily mean it would be changed in WLS as they use different transaction managers and the problem is more than a TDomain protocol issue. But generally when we make enhancements like this we try to keep GWTDOMAIN and WTC on par with one another.

  • WLS8.1 and tightly coupled transactions?

    I have the following scenarion that does not seem to work.
              1. A client calls a method in EJB1
              2. EJB1 inserts a row in a database
              3. EJB1 calls a method in EJB2
              4. EJB2 tries to read or reference the row inserted by EJB1.
              5. The database waits and eventualy an Exception is thrown.
              It seems as WLS treats the XA-transaction as loosley-coupled (see the XA-specification). The behaviour that I want is a tightly-coupled transaction, but that does not seem to be the case.
              - I'm using WLS8.1sp4
              - EJB1 and EJB2 are stateless session beans using CMT and default behaviour.
              - EJB1 and EJB2 uses different database pools.
              - I'm using Informix 7.31 Database and Informix JDBC XA Driver 2.21JC6
              Anybody that have any ideas about this?

              I think the issue is that the data inserted in EJB1 is not available
              for anyone else to see until that EJB's transaction is committed.
              If EJB2 is defined so that it joins the same transaction, it should
              be able to see the not-yet committed data, but if it's a different
              tx, it shouldn't. However, how is EJB2 able to access the data via
              a different pool than the one used to insert the (not-yet committed)
              data?

  • Any plan to support 21 CFR part 11?

    If NI didn't support 21CFR part 11, I must change to another scada program.
    Do you have any plan to support 21CFR part 11?

    The following link might be helpful to you:

    The same goes for Lookout. While it is not by itself compliant with 21 CFR Part 11 standards, it is a design tool that can be used to create an application that is 21 CFR Part 11 compliant.
    I hope that helps.

  • Any plan to support Fujifilm IS PRO RAW(.RAF) file?

    Hi,
    Fujifilm FinePix IS PRO is UV/IR capable camera with S5 PRO system (Nikon D200 body).
    It's RAW structure is 99% identical if not 100%.
    Unfortunately, all Apple products is not support its RAW image because it's not on its supporting list although the file structure is (almost) same.
    Please let me know is there any chance to support this camera in future.
    I can supply sample RAW files if you require.
    Adobe is currently supporting FinePix IS PRO in Camera Raw.
    Regards

    I have the same problem using the RAW-Files of the S5 pro with Aperture. I really would use this greate Apple-Software but I switched to Adobe Lightroom. In Lightroom my Camera is fully supported.

  • Transactions across domains

  • Does ADF security support sub-roles? If not are there plans to support it?

    hi,
    I have following scenario: there are dozens of regions and each region has dozen of facilities and each facility dozens of offices.
    I would like to setup Office roles to have Query permission only and create a new role OfficeUpdate role that has update permissions for this office data, and at the same time to inherit permissions from Office role (e.g. Query permissions), so if I assign a user to Office role he will be able to query only and if I assign him to OfficeUpdate role he will be able to query and update the office data because privilege will be inherited from Office role.
    User can be a member of different offices/facilities/regions. So I would like to, in order to simplify user management, to be able to assign a whole role as a member of another role. By doing this I wouldn't have to assign users to different roles all over again (all users assigned to a sub-role would automatically become members of main role as well) as this is time-consuming.
    But it seems that ADF security does not support this. It seems that ADF security can only deal with roles and not sub-roles? Roles and sub-roles are supported by oc4j container but it seems that ADF security does not support it.
    I would like first to be sure that my observation is correct, and if yes to find out if there are any plans to support sub-roles in future Jdev releases?
    And also if somebody knows, if Acegi or JsfAcegi security supports role-sub-role privilege inheritance?

    I created a testcase that excludes ADF Security and the same behavior can be reproduced, so the problem doesn't seem to be with ADF Security but JAZN.
    Need to further track this issue, but so far it appears that a member role is not sufficient to authenticate and authorize a container managed constraint as used by ADF Security for authentication. This could be a problem with the embedded OC4J only but also a general problem with settings on the system-jazn-data.xml. This is what I need to further evaluate.
    So for now I can't say that this isn't working in ADF Security because its not even getting there

  • Does Adobe have plan to support outgoing HTTPS reuqests

    Hi,
    It looks like on AMS it's not possible to make an HTTPS request at all. I tried with XML class and LoadVars class. It looks like AMS is not even trying to make any connection when the URL has HTTPS:// on it. The online references I was able to find indicate that it's not supported in AMS. If I am not wrong, Does Adobe have any plan to support this in future?
    Thanks

    Hi and Welcome to the Community!
    An authoritative answer to your question requires access to and revelation of "insider" as well as "forward looking" information...both of which are forbidden on this site. Rather, all that can be said is individual opinion and theory. But, based on how things have migrated with BB10, my opinion is that the answer is no.
    Note, please, that there is a vast difference in pricing in different regions of the world. For example, in my country, a BIS plan costs significantly more than the non-BIS plans, making BB10 devices much more affordable (from the monthly cost perspective) than legacy devices that required BIS.
    Good luck!

  • Will there be any plans soon to support problematic captivate objects like smartshapes?

    Currently there is no support for use of smartshapes as buttons in Adobe Captivate SCORM files. Are there any plans to fix this soon?

    hi mjpettitt, i don't know enough about the particulars of your question to give a definite answer. however firefox is a webbrowser that aims to be standards compliant - it renders html an not any proprietary formats. so the long term "solution" of this problem would probably be for Captivate to generate output that complies with web standards...

  • Is there any planned support for the "do not back up" extended attribute for iOS

    Starting in iOS 5.0.1, Apple has introduced a new "do not back up" extended file attribute that will allow an app to store downloaded data into the application folder.  Is there any planned support for setting this attribute within an AIR application or is there currently a way to set this attribute using the existing AIR SDK.

    Yes, this is exactly what I'm wondering too. Without it, we can't build any apps that download content without the risk of the content being deleted.
    Here's the background before Apple introduced the new "do not back up" attribute:
    http://www.marco.org/2011/10/13/ios5-caches-cleaning
    Fortunately, Apple addressed it after that blog post in 5.0.1. See bullet #4 here, quoted below
    https://developer.apple.com/icloud/documentation/data-storage/
    Q:  My app has a number of files that need to be stored on the device permanently for my app to function properly offline. However, those files do not contain user data and don't need to be backed up. How should I store those files in iOS 5?
    A: Starting in iOS 5.0.1 a new "do not back up" file attribute has been introduced allowing developers to clearly specify which files should be backed up, which files are local caches only and subject to purge, and which files should not be backed up but should also not be purged. In addition, setting this attribute on a folder will prevent the folder and all of its contents from being backed up.
    Important: The new "do not back up" attribute will only be used by iOS 5.0.1 or later. On iOS 5.0 and earlier, applications will need to store their data in <Application_Home>/Library/Caches to avoid having it backed up. Since this attribute is ignored on older systems, you will need to insure your app complies with the iOS Data Storage Guidelines on all versions of iOS that your application supports.
    Now we just need Adobe to support the attribute in the AIR SDK. What do you say Adobe?

  • Is there any plan to add RTSP  support in JavaFX?

    I really want use JavaFX in my new project, a web app in IP Camera.
    Current JavaFX  only support HTTP streaming, but the IP Camera is output RTSP stream.
    Is there any plan to add RTSP support?
    I think it is a very important function in surveillance application.
    Oracle should think about it!

    You can create a new feature request for RTSP support against javafx-jira.kenai.com
    RT-3458 camera support for JavaFX is (always) scheduled for the next JavaFX release.

  • Does Apple have any plan to add Persian support in iWork?

    Does Apple have any plan to add Persian writing support in iWork?
    like in the next updates?

    There is support, OSX has 3 input methods for Persian:
    Menu > System Preferences… > Language & Text > Input Sources > Persian/Persian - ISIRI 2901/Persian QWERTY
    but OSX has general problems with placing cursors in the right position in R to L languages.
    Mellel is currently the best solution for all the R to L languages.
    You just missed getting it in a MacUpdate Bundle.

       Hello AkankshaSheoranKaler
    We have done the following, but we aren't able to resolve this issue. Thank you for your help!
    lf
    “This  happen if the software library is not accessible, readable or unmounted (if it is in shared file system).”
    On Enterprise Manager server [nsn175-105], we did the following:
    1. we modified /etc/exports to include this line: /export *(rw,no_root_squash,sync)
    we start nfs service by executing command “service nfs start”.  
    On Management Agent server (nsn175-89), we verified that we are able to mount /export directory of EM server.
    On Management Agent server, we started firefox browser and were able to run successfully https://nsn175-105.us.oracle.com:4904/empbs/genwallet
    After making this change, we ran agent deployment again. We encountered the same error as shown above.
    “You can fix the software library or you can download the agent bits in offline mode.”
    For fixing the software library, select Setup->Provision and Patching->Offline Patching, then select Offline Patching radio button, download: https://updates.oracle.com/download/em_catalog.zip. Next upload this zip file.
    “Try downloading the bits again”
    We are not sure what agent bits are. Would you please explain this and provide procedure how we can download this?
    (Here I have attempted to fix the software library, but I am new to Enterprise Manager and not sure how to interpret this).
