OSB and JCA and AQ adapter

Hi,
Database 10.2
OSB 10.1.3.1
I would like to automaticlly publish changes from databasae AQ to service in OSB.
Is it possible to do it by creating JCA AQ adapter (deploy it t OSB as business/proxy process)
that could listen/dequeue database AQ and invoke a business/proxy proces on OSB ?
Or any other ideas how to force OSB to dequeue AQ itself ?
Regards,
Cezary

Hi. I'm not quite sure if JCA Adapters are available in OSB 10.3.1. But in SOA Suite 11g they are. And the JCA Adapters provide you with functionality you need. You can choose between JMS Adapter and AQ Adapter. Both will poll for new messages on the configured queue and respond by pulling message from queue. You can define frequency of polling and more. So, yes, JCA Adapters are the right choice (you only need to check if they are available for your version).
Confirmed by a colleague: In version 10.3.1 there is at least a working AQ Adapter. There seems to be a problem with the Jms Adapter in this version: it can not handle queue's with Text Message Type......

DB Adapter and jca transport: monitoring and management

Greetings.
We have faced with several issues with DB Adapter and JCA transport proxy. We use pooling DB adapter. As the result - the pooling stop. I would like to know:
1. Is the way to monitor pooling threads of DB Adapter in OSB? I would like to answer the question "does it work?".
2. Is the way to restart pooling in JCA Proxy service? The way we found is re-save OSB configuration in OSB Console, bu it is terrible.
I use:
                    ActivationSpec="oracle.tip.adapter.db.DBActivationSpec"
                    DescriptorName="DescriptorName"
                    QueryName="QueryName"
PollingStrategyName="LogicalDeletePollingStrategy"
                    MarkReadFieldName="IsLoad" MarkReadValue="Y"
                    MarkReservedValue="R${IP[-3]}" MarkUnreadValue="N"
                    SequencingFieldName="ID" MaxRaiseSize="5"
                    MaxTransactionSize="unlimited" PollingInterval="180"

2. Is the way to restart pooling in JCA Proxy service? The way we found is re-save OSB configuration in OSB Console, bu it is terrible.You may restart/redeploy DBAdapter in Weblogic Admin Console and polling should start. Ideally poller transports does not stop polling. Let us know the complete detail if you experienced such issue.

Explain PCK, adapter framework and JCA

Hello Guru's
I have sean lot many materials but still now i am not able to figure out these tree words. i.e. PCK, ADAPTER FRAMEWORK and JCA.
Can any one explain me at ground level what these three words means and relationship between them and where do they stand in the overall XI ARCHITECTURE. And also tell me the uses of all the above words.
Thanks in advance.
arjun

Hi,
>>>I have sean lot many materials but still now i am not able to figure out these tree words. i.e. PCK, ADAPTER FRAMEWORK and JCA.
PCK - called small XI/PI it's a middleware which can do mappings but has to be connected to XI from one side
more about features:
http://help.sap.com/saphelp_nw04/helpdata/EN/99/115281baba404890d2561617a78409/content.htm
JCA - java connectivity that XI/PI uses:
http://java.sun.com/j2ee/connector/overview.html
adapter framework
this is a term under which all adapters (like file, jdbc) and their processing is being described
but please post more detailed questions as answers to most of those
you can find yourself in google ok ?

OSB, DB adapters and complex XML

I'm new to all Oracle middleware products (and it's years since I've written any Java, while I'm being honest), but I've been given the task of taking some existing XML feeds and sticking some of the data in a DB. Well, that's the basic solution I've come up with anyway, and OSB (10.3.1) seems the way to go.
I've seen the JCA DB adapter tutorial at http://www.oracle.com/technology/sample_code/products/osb/index.html - and very good it is too, but I'm wanting to take it a bit further. i.e. do something more complex than a simple 1:1 XML attribute to database column mapping. I want to take the existing XML file that has a relatively complex schema (containing more attributes than we actually need, plus entire sections I want to ignore) and only take the relevant info and put it in the DB table.
The thing is, I don't see any pointers on that, wherever I look on the web. Is it simply a case of hacking around with the xml, xsd, mappings, etc...telling it about the extra fields, and to ignore them...or - given that will probably take quite a while - is there a an easier way using Jdeveloper, Eclipse or something?
Likewise, is there a nice tutorial showing how to create a proxy service and map it to the DB adapter business service? I guess I can figure that out myself, but it's nice to save time and see the 'right' way first...
Any other pointers, before I head off down the wrong path? Good resources, aside from the manuals on here?
Cheers in advance.

If I remember correct, a DB Proxy (JCA proxy using DB adapter) required for cluster deployment , is supposed to use a WSDL specifically generated from JDEV with specific settings.
Ex. I created a db proxy in my development box (Single node OSB domain). The same proxy cannot be deployed in clustered osb domain. The wsdl for db inbound in cluster domain is little different from db inbound in non-cluster env and that has to be created from scratch from JDEV.
I can search my previous mails for the specifics if you should require .
Thanks

JCA and packaging

I successfully deployed a JCA-compliant resource adapter but ran into trouble when trying to use it from an EJB app. It was throwing a ClassCastException when getting the connection factory class from JNDI, although the object coming from JNDI and the variable I was trying to assign it to appeared to have compatible types. The problem was that the EAR and the RAR were deployed separately, so the class of the factory bound to JNDI was loaded by a different class loader than the class in my application. Same class name (and bytecode) but different classloader means different class.
          I am looking at the various ways to work around this problem:
          1. I'm guessing that since the JNDI lookup for the factory is done within the app server (it's an explicit lookup, I'm not declaring the resource location in the session bean descriptor), it's optimized such that the object is not sent over through serialization. If I could force serialization (pass by value) somehow, this wouldn't be an issue. Is there a way to do it?
          2. Put the classes that are visible to the application (the factory, the connection and who knows what else) in the server's lib folder. I'm not too psyched about this option.
          3. Package the RAR inside the EAR (and put the shared classes in APP-INF/classes or jar them up in APP-INF/lib. This isn't optimal either, I don't like the fact that I'd have to deploy the RAR with every application.
          I'd like to know whether there are any other options and which one would be the recommended one. Am I understanding the problem correctly?
          Thanks,
          Alex

I discovered an element in the weblogic-ra.xsd that I had previously overlooked. It's <enable-global-access-to-classes> and setting it to true seemed to solve my problem. I am surprised I wasn't able to find this piece of information by searching BEA's site and the net. There is virtually no information about this element aaside from one sentence in the resource adapter manual.

Topic: XA transactions and JCA 1.5

Hi,
I am new in the area of connectivity and integration and I have a question regarding supporting XA transactions.
I have a EIS that supports XA transactions. Now, I want to integrate this EIS into a J2EE Application Server. Currently, there is no Resource Adapter (RA) implemented for this EIS.
Is it mandatory to supply a RA for this EIS in order to enable this system to participate in XA transactions? Can a EIS be connected to an Application Server without using JCA, and make XA transactions work?
Thanks,
--------------------

If your EIS has data in a database you could use JDBC to access that data, or if your EIS uses a messaging system you could use JMS. These are the easier options.
Otherwise you are going to have to use a JCA adapter to get it to participate in an XA transaction. Its not the easiest thing in the world to do - buy one if you can rather than write one. Otherwise there are a couple of books out there with tutorials, such as the SAMS book Java Connector Architecture, or the Sun book J2EE Connector Architecture and Enterprise Application Integration.
If you do go down the route of writing a JCA adapter, make sure you also read up on XA, such as Mike Spilles articles here:

Mac Pro and DVI to Video Adapter

I just received a new Mac Pro with a GeForce 7300 card and was planning to use it in part to display video on a set of TV monitors using the Apple DVI to Video Adapter. Try as I might I have not been able to get the computer to recognize a TV regardless of the DVI port and using both S-Video and RCA. I now see that in Apple's store the converter is classified as Requiring a "MacBook Pro, Mac mini or Power Mac G5 with DVI port". Not sure if there's any way around this. The adapter has worked fine in the past with both a Mac Mini and a G5 tower. If anyone knows a possible workaround or if an updated adapter is forthcoming I would appreciate the information.

Just to be clear here: There is no way to get S-Video
output from my $~2700 machine (with the stock
7300gt)? Not even with (maybe forthcoming) additional
adapters? This is pretty embarrassing. Actually I'm
sorta angry.
Are there any other options like DVI->VGA->S-Video
maybe? I surely won't dump $150 into the trash just
to have that (supposedly) noisy beast of a x1900
screaming around here. Just for S-Video. This is
silly.
There are VGA to S-Video converters but they cost more than the Apple adapter. Here is one. Probable a bit fancier than you want. There are others.
<http://www.ramelectronics.net/html/PC-TVvideoadapter.html>
The Apple adapter is cheap because all the work is being done in the video card when it detects the adapter. The video card outputs the S-Video brightness and color, and the composite video on the DVI pins that would normally be used for analog red, green, and blue, using the A/D converters normally used for a CRT. The adapter just sends the signals to different connectors. The adapter won't do anything with a card that wasn't designed to output TV video.

Mac Mini and DVI-Video PAL Adapter no picture

Hello,
I have a mac mini g4 (late 2005) and the pal video-adapter to connect this thing to my tv however I don't get a picture out of this on the tv. In the system preferences I don't have the choice to a pal setting but just 800x600 in different colors and 1024x768.
When the mac boots with tv connected (s-video cable) I see some flickering but nothing comes out of it.
Any hints how to proceed here?
konstantin

After rebooting the mac mini with a vga-monitor connected, then unplugging that monitor and plugging in the tv adapter it is working.
If somebody could shed some light, what has happened there I would really be interested..
Konstantin

My MBP Retina doesn't allow the use of two Thunderbolt to DVI adapters. It only works with one TB - VGA adapter and one TB - DVI adapter. However now the color on the VGA connected monitor is slightly different.

The monitors are Viewsonic VA2406m-LED. The Display preferences show all three monitors but one monitor always says "No Signal" if they are both connected TB -> DVI.
The Color on the VGA connected one is slighly off. It seems like I should be able to connect two DVI monitors not sure why this is stopped. Does it have something to do with the Graphics card?

The problem was with the newEgg adapter. I just went to the Apple Store and bought an Apple adapter and the monitor now displays correctly.
For future reference, in case anyone experiences this problem:
the newEgg adapter is part number 9SIA1PU0P88920, described as a Thunderbolt Mini Displayporrt Display Port DP to DVI Adapter for APPLE Macbook Pro Air and the full description says it works for macbook pro, etc.
when this adapter is used, the macbook pro recognizes the monitor, but the monitor displays nothing.
When the apple adapter (MB507Z/B Mini Display Port to DVI Adapater) is used, the monitor displays correctly.
Of course, the individual newEgg part might simply be defective, but I doubt it. moral -- spend the extra $$ and buy the Apple adapter.

Wi-fi: No Hardware Found and USB Wi-fi Adapter

Hello !
I want to explain everything that happened from the beginning. My MacBook Air started giving a problem showing " Wifi : No No Hardware Installed " . Then the problems started . I found a few ways to resolve this problem:
1 . Holding Command + Option + P + R before turning on the MacBook . He goes to the gray screen and restart again. Now release the keys .
2 . Shut down your MacBook and connect the charger . Click Left Shift + Control + Command + Power simultaneously. Generally the macbook league, but if you do not call , press the power button.
3 . When the system starts up activate bluetooth and then turn off . Restart . Should operate normally . Almost does not work sometimes restarting , shut solves .
Note : all these ways are temporary resolutions .
When the Wifi back to work, after some time the system panics and crashes and to shut down the macbook and start it again . When Wi - fi appears : No No Hardware Installed the macbook works perfectly without wi - fi .
I read many articles on forums and I think the problem may be with the AirPort card . I have not been to an apple store to see a budget.
Trying to solve the problem I bought a Wireless USB Adapter: LINK ONE - L1-AW1Un that comes with the installation CD containing the drivers. Use the Mavericks (the latest) installed. After restarting, open the program normally Raillink the Wireless Utility. I connect, create a profile and appears active when connected after a few seconds change to disconected doing it constantly.
Below is the Wireless USB Adapter manual: LINK ONE - L1-AW1Un.
https://drive.google.com/file/d/0B0tn0xatEydORjF5aV96ZFZxQ3M/edit
(MANUAL - Google Drivers)
I did not follow. Unable to create an IIS 7 certificate as shown in the manual. The drivers on the CD and the website are 10.5, 10.6, 10.7;
I need help.
Thank You

Hello Marvyn,
Try install following driver on Ralink's site: http://www.mediatek.com/en/downloads/usb-rt2870rt2770rt3x7xrt537xrt5572/.
After install driver on my MacBook Pro, OS X Mavericks (10.9.3), the Wireless USB Adapter L1-AW1Un works perfectly.
Best regards.

I am considering a Apple iMac but would be interested in adding a second monitor. Does it have to be an Apple monitor or can i add any monitor with a thunderbolt cable and DVI or vGA adapter?

I am considering a Apple iMac but would be interested in adding a second monitor. Does it have to be an Apple monitor or can i add any monitor with a thunderbolt cable and DVI or vGA adapter?

I found that the Thunderbolt input accepts the mini-DVI (in my case converter to VGA for a tutorial use monitor)
BUT, you have to really oush it in 'til it clicks. I thought it too loose until I tried it. works just fine!!
i get a solved for my own LOL

What is the recommended way of connecting to repository out of WebDAV, RMI, JNDI and JCA connector ?

What is the recommended way of connecting to repository out of WebDAV, RMI, JNDI, and JCA connector possibilities provided by CQ 5.5?

Hi dp_adusumalli,
I recognized your list of ~8 questions you posted at around the same time, as I received that same list in our customer implementation from Arif A., from the India team, visiting San Jose. :-)
I provided him feedback for most of the questions, so please check back with Arif for that info.
For this particular question, can you provide specifics for the types of interactions you are interested in?
Understanding the kinds of things you need to achieve will help determine which of the CQ/CRX interfaces is best suited for the task(s).
I've collated a few points on this subject on this page:

Is the Apple Digital AV Adapter and the Apple VGA Adapter the same thing

is the Apple Digital AV Adapter and the Apple VGA Adapter the same thing i want to get a ipad and i want to no if there the same thing before i buy it i would want it for the web for pic but for videos too

VGA is an analog signal, while HDMI is an uncompressed digital image.
The uncompressed digital image is more superior.

OSB is staless and how it achieves Asychnorous call back

Hi All,
I got to know OSB is statless and BPEL is stateful and hence it supports Asynchronous Call back reliably with Correletaion ID which is also
supported in Oracle Enterprise Service bus and it is now knows as Mediator in 11g.
The question I have is
A) Since OSB is stateless which means we can't implement Asynchronous call back kind of integration pattern.
B) If my proxy service has to call WebService Asynchronopusly and don't wait for the response continue with the rest of the
execution once the response get's received from the web service it has to send the details to the source.
I am indeed aware of one particular indirect approach is this kind of stuffs could be achieved in JMS queues by means of correlation IDs by
means of using two queues one for request and another for response.
If anyone had a better suggestion/thoughts please do provide the same at the earliest.
Many Thanks,
Dini
