What's the best option for event generation from an Oracle database?

Hi all,
I need to interface from an oracle database into WLI (or elink if need be). The
code that needs to call this interface is written in pl/sql in the database.
What is the best way to enable the pl/sql to make a call to WLI?
I know you can set up an event trigger on a table using the sample DBMS adapter
so that it will send info to WLI via the events table in the database but this
is what they call a pull event(i.e. the adapter is actually polling this table
for whenever an event gets put into it I think).
Has anyone ever done a push type event? (e.g. calling java code from pl/sql that
sends event to WLI)
Or anyone know whether the new JCA for Oracle Applications will help with this?
I am using Oracle 8.1.7 so don't have any extras with Oracle Apps.
thanks all

Adam,
I have not implemented an push event adapter with Oracle. However, I
know the trend that seems to be happening in the industry and I can say
I agree 100% with it's implementation. I am seeing vendors using
Oracle's Advanced queuing features to push events out to other
applications. One interface for AQ is PL/SQL using DBMS_AQ, DBMS_AQADM,
and DBMS_AQELM packages, so you would not have to rewrite your current
business logic. Although I have not done the leg work, logically, this
would be the approach I would take if tasked to implement an Oracle
event adapter.
For more information register (free) for an account on Oracle Technology
Network (OTN), then go to the following URL:
http://otn.oracle.com/docs/products/oracle9i/doc_library/release2/appdev.920/a96587/toc.htm
Note: (the url goes to Oracle9i, as I couldn't find the link to 8i, but
8i AQ in will work just as well)
Cheers,
Chris

    What is the best option for tethering my IPhone 4s with my iPad? (the iPad is wifi only)

    #1. Understand that if you switch carriers, you can NOT take your existing iPhone with you. It won't work. You will need to purchase a new one.
    #2. Your only choices are Sprint and Verizon. Decide who has the better coverage in your area. Keep in mind that you will NOT be able to get simultaneous voice and 3G data on either of these, as their CDMA networks do not support it. The U.S. T-Mobile network is not supported and is not fully compatible with the iPhone as it operates on a rarely used frequency compared to the rest of the world.
    #3. What in the world are "niners"? Do you mean you want to be able to keep your existing "phone numbers"? If so, that should be no problem. Most numbers in the US are now portable.
    #4. Consider WHY you want to switch. If the issue is really price, you're not going to see much of a difference. A few dollars a month at best for comparable voice and data plans.

  • What is the best option for 'update.... set' in owb?

    Hello.
    I have been reading on a number of ways to implement following query in OWB:
    update TABLE A
    set Value F = (select Value B
    from table B
    where (nvl(trim(A.valueC),trim(A.valueD) = trim(B.ValueF)
    and substr(A.valueG,1,2) = trim(B.valueH))
    or ( nvl(trim(A.valueC),trim(A.valueD)) is null
    and trim(B.valueF) is null
    and substr(A.valueG,1,2) = trim(B.ValueH)
    The table A and table B do not have a relationship.
    Key lookup - some of you recommend not to use it as it is not very good.
    Set Operator or Joiner? What would be better?
    I created a function for this query, but i cannot use it in the map because i get this error:
    API8003:coonection target attribute group is already conncted to an incompatable data source. Use a Joiner or Set operator to join the upstream data first before conncting it into this operator.
    What would be the best way to do it? how i can pass the parameters from two different tables into my function? What feature of OWB would be the best option i cannot use for this?
    Or my best bit to re-create it as a procedure and run it that way?
    Thank you very much for your help

    Hopefully this is helpful and it makes sense written out.
    First, I'm not sure if there are some parenthesis missing in your update statement because I can't tell for sure whether the statements separated by the 'or' should be considered separately [ as in "(a = b and a=c) or (c = d)" vs "a = b and a = c or c = d" ] or if the logic is exactly as written. My suggestion is based on the idea that the query is exactly as written -- if parenthesis were missing, insert them as appropriate.
    My suggestion is to use a join. Even though you say A and B don't have a relationship, they sort of do based on the update statement.
    I would suggest that you start with source A and insert an expression operator. You'll send in ValueC, ValueD, ValueG. You create three outputs:
    BValueF = nvl(trim(A.valueC),trim(A.valueD))
    BValueH = substr(A.valueG,1,2)
    NullValue = nvl(trim(A.valueC),trim(A.valueD))
    Then add source table B and insert another expression operator. You'll send in ValueF and ValueH. You create two outputs:
    TValueF = trim(B.valueF)
    TValueH = trim(B.valueH)
    Then insert a join operator. For ingrp1, you'll drag over whatever can uniquely identify A and the three outputs from the expression. For ingrp2, drag over ValueB and the two outputs from the expression.
    Then your join condition will be
    BValueF = TValueF
    and BValueH = TValueH
    or NullValue is null
    and TValueF is null
    and BValueH = TValueH
    Then add your target table A, set it to update on the unique key. Drag the unique key from the joiner to the unique key on A, and drag ValueB to A's ValueF.
    Hopefully this makes sense written out. I didn't test this, but it looks logically correct on paper.
    Good luck,
    Heather

  • What is the best option for storing my iphoto library on the cloud?

    I was curious as to what people are doing (other than backing up to external HD) for backing up the iphoto library?  Anyone using any cloud solution out there for storage?  What are some of the best options?  I have around 30,000 photos in my iphoto library.

    There is no good solution for storing the Library in the Cloud. The amount of data involved means that uploading or downloading is very, very slow. We do see posts on here from people trying to restore from a back up to the Cloud wondering if it's possible to speed up the download currently estimated in days. Running a Library from the cloud is just painfully slow - people have tried it and that is the consensus.
    However, as part of a comprehensive back up plan there is a lot to be said for backing up your Photos to the cloud. Not as good as backing up the whole Library, but as a "last line" you at least have your photos. There are many options: Flickr, Picasa, SmugMug etc. However, check the terms of your account carefully. While most sites have free uploading, you will often find that these uploads are limited in terms of the file size or the bandwidth you can use per month. For access that allows you to upload full size pics with no restrictions you may need to pay.

  • What is the best option for generating .wmv video working on Mac?

    I am working on a mac. I need to generate my output in .wmv. I am exporting as .mov then using MacX converter to convert to .wmv. The quality degrades too much. What is the best way to generate .wmv?
    Thanks in advance.

    YOur statement is way too generic and vague. You have not provided any exact settings,  version info, details about the footage etc. That asude WMV is a compressed format and wil always degrade.

  • What is the best Path for a J2EE developer with oracle?

    Hi,
    I am a J2EE developer, for the time being I work at a Commercial Bank as an enterprise application developer. I have learnt java when I was following a local IT diploma and with the help of books, works at my working place and the internet , today I am developing J2EE applications with JSP,Servlets,JSF2.0,EJB3.0 and third party JSF libraries etc. (I am also developing softwares using other programing languages such as Asp.net, C#.net, WPF etc, but I prefer to be in the java path). Other than that, I'm also working as the UI designer of most of our applications.
    I have those skills and practice after working for 4 years as a web/enterprise application developer & a UI designer, but now I have to focus on some paper qualifications and hence I am doing BCS.
    Now I want to be a java professional in Oracle's path, and I need to know what is the best path I can select to move with Oracle. I finished my classes of SCJP , but didn't do the exams as there were some rumors that Oracle will dump those exams in the future. I am interested in Oracle university, but I am unable to even think about it as I live in Sri Lanka and don't have that much of financial wealth to go USA and join.
    So I really appreciate if any Oracle professional could suggest me the best educational path according to what I mentioned about my technical and career background. Because I have a dream to join Oracle one day as an employee and being a good contributer to the same forum, which I am getting helps today!
    Thanks!!!

    As you can see on our website, Oracle did not retire the Java certifications. You can browse through the available certifications and hopefully help to determine your path.
    http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=140
    SCJP has now become Oracle Certified Professional Java Programmer. You can find more info on those exams on our website here: http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=320.
    Regarding training, perhaps live virtual training would be an option for you. You can find more information at http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=233.

  • HT4623 my phone is giveing me error 21 since i updated it to ios7 it wont turn on it wont restore i have tried several times to restore the device but im really at a loss what is the best option for me ?

    hi, my iphone 5 has refused to restore after i updated it to ios7 ...... it will not turn on, it will not restore i do get an error 21 mesg and i have attempted a couple of fixes from the net, but nothing seems to work . i have no acces to my phone it just is dead whats my best option, do i need to send it to apple ?

    Hello Peter,
    Thank you for using Apple Support Communities!
    Error 21 is part of a range of error codes generally indicating that other software is interfering with the restore process.
    Check out the troubleshooting from this article named:
    iTunes: Specific update-and-restore error messages and advanced troubleshooting
    http://support.apple.com/kb/TS3694#error21
    Error 20, 21, 23, 26, 28, 29, 34, 36, 37, 40
    These errors typically occur when security software interferes with the restore and update process. Use the steps to troubleshoot security software issues to resolve this issue. In rare cases, these errors may be a hardware issue. If the errors persist on another computer, the device may need service.
    Also, check your hosts file to verify that it's not blocking iTunes from communicating with the update server. See the steps under the heading "Blocked by configuration (Mac OS X / Windows) > Rebuild network information > Mac OS X > The hosts file may also be blocking the iTunes Store." If you have software used to perform unauthorized modifications to the iOS device, uninstall this software prior to editing the hosts file to prevent that software from automatically modifying the hosts file again on restart.
    All the very best,
    Sterling

  • What is the best option for working live off external hard drive?

    I have 3 iMacs all networked together and working off 1TB of files stored on an old MacPro. I'm wondering what my best option would be for upgrading moving forward. I need more space (preferable 2TB or more) and I'd like the connection to be as fast as possible. A server seems like overkill ...
    I have an external 3TB WD Cloud backing up all of the files, but it's far too slow to work off of live as it needs to 'wake up' every time I ping it.
    Would running a 'headless' Mini directly off my router work? Or perhaps attached to one of the iMacs?
    Other options?
    Thanks in advance

    Hi there,
    Ive always followed the idea that journalling is turned off, so I would follow the advice given and turn journalling off.
    In addition I would also make that drive "private" to spotlight so it doesn't search or catalogue there.
    If its of interest, I've always formatted my drives in the following way
    make 2 partitions,
    partition 1 - make this about 10% of the drives capacity and label DO NOT USE
    partition 2 - make this the remainder of the capacity
    the reason being (So Im told by the drive gurus) is that the first sector contains the volumes boot block - this can get corrupted/damaged so having it partitioned like this means you can erase it safely whilst keeping your media.
    Ive followed this for years and it has worked on the few occasions a drive has misbehaved.
    cheers

  • What is the best option for my process

    Hi Gurus Can any one guide me which is the best available option for my business process.
    in our client process We have a Final Product(say A). and two Vendors (say Vendor1 and vendor2)
    This Final Product is made up of 3 other parts Lets say B,C and D.
    So The client buys Product B and Product C from the Vendor1 and Product D from Vendor2
    The vendor1 supplies the both the parts(A and B) to Vendor2.
    The Vendor2 Takes the Parts B, C and Joins with Part D and deliver the final product A to the client.
    There is no assembly cost for Vendor2- he charges for only part D.
    Can anyone tell which is the best available option for my client.
    Please help me ASAP
    Thanks

    Hi Amar,
    There are many other factors that you need to take into consideration to define best approach for the process.
    You have to know what type of control you want to have of the "production" of the product "A". Who is the owner of the components B and C while they are at vendor 2.
    Who is the payer and how are you going to receive invoices of vendor 1 (you receive invoices for components according to the quantity of product A you receive in your company, or you receive invoices for all B and C received at vendor 2??)
    Its no easy to give you a feedback without more information.

  • What is the best option for travellers?

    Hello everyone, I am from Peru and will be travelling to the States later this year. My main concern is staying connected while I'm there, so I would like to know if there is a solution for people like me who would like to use the service for a short period of time.
    First of, I'm still not sure if Verizon is CDMA only or also GSM, I already own an unlocked GSM phone that I would like to take with me and use while I'm there. I don´t really care for the minutes or texts as much as I do for data, it's what I'm mainly looking for.
    I will only be there for 10 days. So, does Verizon offer aything that could suit my needs? 
    Thanks in advance for your help.

    Thanks SuzyQ, you are correct. Verizon is CDMA only.
    @vigmak, if you will only be in the USA for 10 days we would recommend our Prepaid service. Click here for more information on our Prepaid service.

  • I am looking to upgrade my Mac to an ideal gaming, photo, and media creation system. What is the best option for me if I like to play The Sims 3 games?

    I am looking for suggestions on the ideal gaming macbook. I enjoy playing the sims 3 but it runs really slowly on my current Macbook. I bought it back in 2011 and ive kept up to date with software updates, etc. Just needing some help deciding which system will give me the biggest bang for my buck.

    16GB RAM upgrade + an SSD upgrade (biggest wallet can afford).
    However, if it is a 13" model, there is an inescapable wall, since those carry just a single GPU and share the video memory with the rest of the apps. 15" and 17" models have a  higher powered, separate and autoswitching GPU and up to 1GB of dedicated VRAM.

  • Laptop Cooler: What's the best option for a 17" MacBook Pro?

    I've noticed that apart from my previous problems, I also encountered overheating on my laptop - specifically on the upper left hand part, near the plug/magsafe 2.
    I was thinking that maybe I should get a laptop cooler. I only know two types of cooling techniques: fan or cooling pad.
    Which one should I consider? And are there any other options?
    Given with this problem, is it also the reason for my battery's failure?
    Hoping a for your response. Thanks.

    PS.
    The other day, I stated my laptop auto-restarts by itself when RENDERING (only) with iMovie. Sometimes it does the same RANDOMLY when editing via FCPX or when I use more than 2 applications for a prolong period of time (say an hour or so).
    Today, I play Diablo 3 and put all my settings to LOW. I played with my Monk (Lvl 55) for about 15-20 minutes beofre it restarted again. That's when I noticed that my laptop was extremely hot on certain areas as well.
    So what will it be? Battery, OS X error, both, or Video Card failure?
    Let me know what you think! Thanks!

    Thanks! I wanted a case that would be durable but not to heavy or whatever, and I am going to check out the Speck cases

  • What are the best options for creating a PDF with bookmarks and a hyperlinked TOC?

    What I'm interested in is whether or not there is an alternate process I could follow that would side step Word 2011's inability to export to PDF with bookmarks and hyperlinked TOCs. How do you create PDF documents with bookmarks and hyperlinked TOCs in your documents?
    Some background:
    In Word 2010 and 2013 for Windows (and I'm sure this applies to older versions as well), you can export documents to a PDF file format where the exported file will carry over the bookmarks and hyperlinked table of contents. Specifically, by making specific text headers, will appear in the final PDF file as bookmarks on the side (see image taken from Adobe's website).
    Regarding the table of contents, using Word's built in Table of Contents feature successfully ports the ability to navigate to a specific section by clicking on its chapter in the table of contents to the finished PDF file.
    I've read several forum discussions that say it's not possible to do this from Word 2011, so my current solution is to just finish all documents on a Windows machine (either with parallels or a separate computer). The alternate process flow of creating a word document, exporting it to PDF, then rehyperlinking everything in Acrobat is just too time consuming to consider.

    Hi, beejasaurus
    I found a possible kluge from this discussion here
    https://forums.adobe.com/thread/1008480
    Create the hyperlinks in Word, save the file
    Open that file with Pages, export as PDF.
    The links work from that PDF.
    Note, I did not try this with TOC but it worked with hyperlinks embedded in the Word document
