Question about Composite Application Framework CE Expose Service as WS

hi
here is my question
i try NetWeaver CE with document "Service Composition with SAP Composite Application Framework Capabilities In SAP NetWeaver CE 7.1_0_.pdf"
but i cannot expose Application Service's query as Web Service like page 42.
the Library page said that because it's because the method ganna return muti-...
i wanna use caf of netweaver ce just like i used with caf of netweaver 7.0
What alternatives are there? if i have to get a list to display on VC.
thank you and good day.

it can use in EhP1

Composite Application with RESTful Web Services

Hello!
Is it possible to build Composite Application with RESTful Web Services only. I use Glassfishe 2.1 and OpenESB 2.1.
Can you point me on some tutorials on the net to read about using RESTful Web Services in BPEL?

Hi Gabriel,
Let me try to answer some of your questions:
1) The "Requires Secure Access" attribute of a resource handler controls whether this handler must be accessed/consumed only over SSL (HTTPS). Oracle Database Cloud Schema Service is only offered over SSL, so this attribute does not have any effect on RESTful services deployed in this environment (because secure access is always required and there is no other way). That said, if you want to access such web service from your own APEX instance, your instance must have Oracle Wallet configured with appropriate SSL certificate.
2) The URI parameters are not required. If your web service returns data for many entities (for example, list of employees in employees/), you may not need a parameter. If your web service returns data for one specific entity (for example, details of one employee in employees/{id}), you may want to identify that entity with a URI parameter.
3) You can have many URI parameters, for example: customers/{id}/orders/{order_id}.
4) Yes, these are the same HTTP methods/verbs you would use from PHP.
5) If you are trying this POST example from your own APEX instance (not Oracle Database Cloud Schema Service) and you are trying to access a web service over SSL, then it is likely that the Oracle Wallet used by your instance does not include the required SSL certificate(s), or the Oracle Wallet is not configured at all.
6) I recommend to check RESTful Web Services for the Oracle Database Cloud white paper and Oracle REST Data Services Developers Guide. Oracle REST Data Services is the technology that enables RESTful services in the Oracle Database Cloud Schema Service.
You can certainly create your own web services in the Oracle Database Cloud Schema Service and consume them from the same environment.

Using Composite Application Framework to deliver global HR applications

Hello,
I'm new to Composite applications but have experience with Web development and Web services.
Our business case is the following:
- Working on HR applications
- The customer is a group made of 3 companies.
- We have 2 separate back-end system, one global for the group and one dedicated the company
- Some HR business processes need to be performed on both the global and the company system. Exemple: Hire of an employee. Depending on the company the employee will work for, some data needs to be created on the company system and on the global system
I believe this can be achieved with Composite Application Framework. I guess, front-end application has to be build (using Composite Designer?). What I don't know is what type of technology is used to build the front-end application?
Finally, the idea behind this is to replace the current solution: multiple interfaces between the group system and the company system.
Thanks for your feedback, any suggestion or tip would be most than welcome!
Laurent

While I was searching the web for some answers, I found out you can create web based composite applications using web dynpros for Java.
Is it possible to do so with web dynpro for ABAP? I guess we can build an abap web dynpro application that connects to different web services from different back-ends to retrieve and update data. Can anyone confirm this?
Thanks,
Laurent

Some questions about iOS system framework, APNS and so on

Hi everyone!
im quite interested in iPhone developement.by reading some dev books of iOS i can learn the general steps of creating an iPhone app. however, i cant find much of iPhone's system archetecture or framework information on the internet, so sometimes i was confused by the running process and principle of an app. so, im wondering cannnnnnn u guuuuuuuuuys doooooooo meeeee a little favor by answering the following questions and i appreciate that:
1. can u recommend some articles or sites from which i can take a look at the system framework of iOS?
2.'backgrounder' is an application for jailbroken iPhone to run an app in the background, i.e. multitasking. do u know what's the principle of 'backgrounder'? can u offer some links that i can get more information of 'backgrounder'?
3,the function of Multitasking, as Apple mentioned in the release of iOS 4, brought another word 'APNS', i.e. apple push notification service. i googled APNS and learned that the servers are provided by Apple and perhaps the servers are located in the U.S. so im wondering, if im using PUSH message, does that mean each PUSH message gotta travel between my country and America twice? if it's true, its gotta cost a lot and there'll be huge delay! and since APNS are maintained by Apple, is it correct to say that Apple can read every PUSH message? and the last question, there're lotta companies providing PUSH messages, and is Apple able to handle all the PUSH flow? that's really great burden i think!
im a college student and an iPhone rookie, and people around me dont know too much about Apple and iPhone, so i have to ask professionals like u for help. ur reply can really help me a lot and im looking for ur reply eagerly. sorry for my poor english and THX a million.

How to access XI_AF_MSG table in Composite Application Framework Java Code

Hi Experts,
I've no knowledge about PI. In one of my projects, I need access the XI_AF_MSG table of PI through java code in a composite application.
How do I access this table? I've searched this forum for this query but the replies say that any SQL editor can be used to access XI_AF_MSG table. But my question is; How do I get the login details of the database? In the first place, how do I access the underlying database layer of PI? Is there any JAR file which can be used to make the connection?
It would be of great help if any expert on this can give me a detailed reply.
Thanks a lot in advance.
Best Regards,
Nitin

Hi Nitin,
The AFW runs on the J2EE Engine, so this table is in the Java Schema of the database and thus not visible in the ABAP stack. I guess you can use any tool your database provider offers for looking at table contents (e.g. SQLPlus).
Regarding how to access the table please contact you basis administrator they will have access to the tables as they have j2ee_admin login ids and pwds.

Newbee questions about XE application builder

Hi
I find that Oracle support someting that we can use to build some real database driven applications
i have some questions about it :
1-Does this application builder differ from Oracle 10g R2 Application builder ? i means is it limited ?
2-Does any one use it to build a real world application that works some where in some business place ?
3-what is its behind code and technology , does it use JSF and managed Beans ? how i can see the generted codes ?
Thanks

Question about managing application licenses together with netboot

Hello
So far I had made no experience with an MacOSX Server netboot configuration but we plan to introduce it in some weeks. Therefore we are "wondering" how management/assignment of application licenses is working in a netboot configuration. Normally in a local MacOSX configuration licenses for application are in generally assigned on the application (some are bound to a certain user name, others to the CPU ID) and is valid for all users login to the same computer. How and at which time are application licenses (for example MS Office 2004, Adobe Acrobat etc.) assigned in a netboot environment?
Many thanks in advance for any clarification and with best regards, André Müller

Hi Andre,
Is this a technical or legal question Either way it is an interesting question about a major grey-area, and I wonder if anyone has the right answer.
Boiling your question down to specifics, it could be...
I have 15 individual Photoshop serials. I want to run Photoshop off a NetBoot image for 15 simultaneous users. Can I install one serial on the image, and allow 15 users to open Photoshop simultaneously. What if I want to install the image on 20 machines, but only 15 users will ever use Photoshop simultaneously.
There is a technical answer and a legal answer to the question. I don't know if there is a 'right' answer since multi-user installations of titles that are technically possible under NetBoot may not be allowed legally under the user license agreement you committed to on breaking the seal on the software. And these agreements are different for different countries.
Here's the technial answer. Sometime before OSX server 10.0, when Apple introduced netboot technology, developers were advised not to perform network scans checking for duplicate serial numbers when aps start up.
In practice this means you can install software title on your image, activate with a serial number, and it will not conflict with the other identical versions of the same application on other images on the network.
FileMaker Pro is the only software I am aware of that doesn't play by these rules, altthough it no longer checks when the applicaton starts, but when any FMPro network activity is started.
Here's the leagl answer. It depends on the title and the country you are in. The legality is definded under the eulas for the titles concerned. I don't know if the leaglity has ever been tested in a court of law in any country in this context.
The easy way to do the right thing for some titles it to purchase a multi-user serial number, ie. a single number which will work for 5 or 10, 20, 50... etc. users. Fore example, FileMaker has a volume licensing serial number which I beleieve can be purchased in increments of 10 users. However, not all titles offer this option, though, and it's difficult if you need 12 copies and have to buy 20.
Sassafras software http://www.sassafras.com/ sells Keyserver, which may be an appropriate solution. Keyserver tracks installations and authenticates serial numbers to ensure no more than the licensed number of copies can be run at the same time.
I don't think I've answerede your question for you but hope to have expanded the contxt of the question for other suggestions.
Good luck,
b.

Question about evictor, application performance, and log growth

Hello,
I've got an application that using two BDB environments, one with critical data and one with data that can be reconstructed, just for the sake of backup convenience. For a while, I was getting OutOfMemoryErrors with increasing frequency. This caused the app to crash without closing the databases or the environment until the recovery time was around 30 minutes. After reading through many of the posts here and trying various workarounds, I got to a state where that stopped happening. I think that what did that fixed is was decreased the cache sizes.
Then, I was seeing what appeared to be evictor deadlocks. The application would hang for thirty minutes before a monitoring script that I've got would detect that no work was being done and would restart the application. Another round of searching ensued and I seem to have gotten it to a state where it doesn't run out of memory or deadlock anymore.
After getting rid of all these issues and letting it run for four or five days, the size of one of the critical BDB environment was 550GB. Since it was almost filling the drive, I moved it aside and created a new BDB for the app to use. Now, I'm trying to figure out what happened. It looks like the BDB contains about 15G of actual data.
It seems like everything starts out fine and then, somehow, it starts to collapse under the weight of itself. I'd like to figure out what type of abuse I may be guilty of that could cause this.
Here's a little bit about my application:
First (critical) BDB environment:
- add only, no deletes
- two databases
- average data sizes are 1k and 11k respectively
- average key sizes are around 80 and 16 bytes respectively
- almost no locality of reference to access pattern in either
- minimal lookups, mostly used as an archive
- cache size is 1MB
- 8 threads reading/writing, 40 threads reading only
Second (reconstructable) BDB environment:
- six databases
- five databases are mostly add with purges of two-week-old data
- one database has frequent adds and deletes
- lots of lookups, things are likely to be looked up shortly after they're added
- cache size is 64MB
- 40 threads reading/writing
On both environments,I've set je.evictor.forcedYield=true.
I'm running the JVM with:
-Xmx1800m
-Dje.adler32.chunkSize=8192
-XX:+UseMembar
JVM version is:
java version "1.6.0_01"
Java(TM) SE Runtime Environment (build 1.6.0_01-b06)
Java HotSpot(TM) Server VM (build 1.6.0_01-b06, mixed mode)
BDB version is 3.2.23
OS/Kernel is:
Linux app2 2.6.9-42.0.10.ELsmp #1 SMP Fri Feb 16 17:17:21 EST 2007 i686 i686 i386 GNU/Linux
So, my question is:
What could cause the critical database (especially with no deletes) to grow to 550GB when there's only 15GB of data in it? It was my understanding that the cleaner should take care of any unused log file cruft. It seems like the log files grow faster as the performance gets worse. I have no idea which is the cause or the effect.
And, I guess the real question is how can I prevent this in the future?
Thanks,
-Justin

For the record, the problem was that the user's cache size was too small for the size of the database thereby creating a large number of records in the log when eviction of dirty records occurred. The cleaner was unable to keep up with the log load.
Note to readers: eviction of dirty records causes records to be written to the log. JE has to evict to somewhere and the log is what it uses.

Question about multiple application modules.

Hello,
Suppose I have 2 database schema’s. For both schemas I have 1 application module. All view objects are in the same project.
For each application module I have an application definition.
Is it possible to link between these two applications? Because sometimes these database schema’s link to each other and you would like to jump from one application directly to the other.
For example you have orders locates in 1 DB schema and customers in another DB schema.
You would want to jump from the order directly to the customer details in the second schema.
Is this possible? Or do I need to make nested application modules etc?
I can find very little info about this; the JHS def guide does not offer much information about multiple application modules etc.
-Anton

Anton,
Yes, you can jump aroundd as you like.
You just can't use view links between VO's based on different db schema tables.
Nesting AM's doesn't help there, the DB connection of the top-level AM will be used.
Why don't you create synomyms for the tables in the other schema?

Questions about Real Application Testing(RAT)

Hi All,
We have a production database running on 10gR3 on a server with local drives, while we have a Oracle 11gR2 DB running on a server with NFS mounts (using S7310 - AmberRoad) i.e. Faster and better storage.
We captured the load on 10gR3 and replayed it on 11gR2. We noticed the following:
(1) Replay is considerably slow even though Oracle11gR2 instance has a faster storage. We suspect that it may be something to do with the buffer cache / SGA because there is nothing in cache on the target (we didn't shutdown 10gR2 DB for capture) – what should we do then?
(2) To make sure that we can take the advantage of cache, we replayed the load 2nd time right after the 1st replay and everything ran to our surprise. So we are wondering how’s that possible since we did not restore the DB as we do not want to wipe off the cache (chicken and egg situation)? Does Oracle rollback the changes after the replay?
(3) Do we have to restore database on Target every time we do replay? But if we do that then we won't have anything in the SGA.
So we need your advise and also would like to know how everyone else is doing this testing?
Regards,
RJiv.

DB Replay's workload capture facility allows you to either start capture from a closed (mounted) database (capture starts upon opening the DB), or to begin capture mid-stream during normal activity. Starting capture on the production system from a closed database eliminates the divergence in performance resulting from a primed cache, as well as possible data divergence issues from open, partially-completed transactions at the time the capture started.
For many customers, it will clearly not be possible to close their database during peak periods (!!)
One way to address the cache priming issue is to start capture in production from a closed state during a low period of activity, and the allow capture to run through the peak period.
Another approach is to start capture mid-stream with the DB open and to run capture for a long period (long enough to stabilize the cache). When performing the replay, begin a new AWR snapshot after the cache has stabilized.
Your question about running the replay again after the first replay is done is confusing. Of course you will not get meaningful data from that, since replay must begin from the capture start SCN. If you run replay twice in a row without reverting the database to the capture start SCN, it will be applying meaningless changes to a database in a state that is unlike that of the original. You will be testing the data errors codepath instead of real performance.
It is typical to enable database flashback on the repay database so that it can be repeatedly reverted to the capture start SCN for testing under a variety of scenarios.

Question about worklist applications

Hi
i tried to do the example listed in the Oracle BPEL developers guide ( "Building a Worklist Application Using the Worklist Service APIs" ) and when it comes to these
step : "Task task = (Task) tasks.get(i);" I get confused because I don't know if this Task is really a oracle.tip.pc.services.hw.task.tasktype.impl.Task.
Also, I printed the class name
Object obj= tasks.get(i);
System.out.println("Class name " + obj.getClass().getName());
and I got that the value returned was a oracle.tip.pc.services.hw.worklist.WorklistTask
am I wrong?
Thanks Nicolas Fonnegra M

Hi Nicolas
It's important to note that there is a difference between the local Worklist Service APIs and the Remote Worklist Service APIs.
The local API is based around oracle.tip.pc.api.worklist.IWorklistService and its implementation oracle.tip.pc.services.hw.worklist.WorklistService.
The remote API is based around oracle.tip.pc.services.hw.worklist.RemoteWorklistServiceClient.
The remote API provides only a sub-set of the functionality offered by the local API. It is recommended that you use the local API, unless you have to host your worklist application remotely from the workflow service.
The local worklist APIs use the class oracle.tip.pc.services.hw.worklist.WorklistTask to represent tasks, which provides more methods than the class oracle.tip.pc.services.hw.task.tasktype.impl.Task used by the remote APIs.
I suspect that you are using the local worklist API, in which case you should be casting to WorklistTask, not Task.
Hope this helps

CAF (Composite Application Framework) and ESA

Hi,
As far as I understand, XApps is presented as a piece of Netweaver (the column on the left side of the NetWeaver stack), an XApps is also a kind of business process based on several applications (or services ?).
XApps runtime and composition platform is the CAF and not NetWeaver ?
So I am confused and I do not understand if
- ESA and XApps is the same concept
- ESA and XApps are not based on the same technology
- XApps will be part of the Enterprise Services Repository and CAF will be rewrtitten to be based on XI so that the vision and the strategy is coherent
If someone ca nclarify, I will greatly appreciate.
Cheers.Christophe

XApps is a concept. There is no general implementation of it. You can write Xapps in Java, In ABAP, or whatever. However, there are nice tools in development to do XApps, which are completely Java based.
> XApps runtime and composition platform is the CAF and
> not NetWeaver ?
CAF does run on NetWeaver. As it has a "Framework" in it's name it naturally should not contain a server environment, should it?

> So I am confused and I do not understand if

No.
> - ESA and XApps are not based on the same technology
Yes.
> - XApps will be part of the Enterprise Services

where did you hear this?

Question about Messages application and AIM.

Hello, I purchased my first apple device last year (iphone) at which point I created an iCloud account and received an @me email address. This is also my Apple ID. Later in the year Apple also gave me an @icloud email like everyone else. I am enjoying my iphone very much and this year I decide to purchase my first os x device (macbook) soon. This is what leaves me to my following questions:
1. I wish to use the Messages application just for iMessage and not AIM or any other IM service. It is my understanding that about 2 years ago .mac and mobileme users were having AOL create Lifestream profiles for them without pemission. Now I have never been a .mac or mobileme user and only signed up icloud last year as previously stated. I just want to know if AOL is still creating these profiles and if they affect icloud users? I could not find any information about this issue being resolved. Would using the Messages applicaton just for imessage have the risk of having my icloud email have a Lifestream profile created for it?
2. I am aware that when setting up my macbook for the first time it will ask to sign in to with your apple id and then into icloud. I plan to do this. I am told that this will make me signed into imessage automatically in the Messages application. What I want to know is if this will make me sign into AIM automaticlly too? I have no intention of ever using AIM so I hope this is not the case.
I hope I have made myself clear as English is not my fist language. Any help with these questions is greatly appreciated. Thank you.

Hi,
The last bit first.
iChat was the application used before Mountain Lion and Messages.
It could only join the AIM, Jabber and in iChat 6 the Yahoo services.
These are Instant Messaging services so the text sent between you and a Buddy tend to be referred to as IMs.
The AIM site I linked to above has an Option (when you can log in there) that allows your to turn this AIM feature Off.
Some Jabber servers can do it but it tends to be an option the person running the Jabber decides to do or not.
If a Server is set up to allow Off Line Messaging then those have to be stored.
These can a concern for the person running the server; either with storage space in the first place and for issues around governments want to "see" the data.
A part of the iChat and Messages apps perform a "Listening" function when you turn your computer On but do not launch the App.
This Listening will start up the App if anyone send you an iMessage and AIM or Jabber message.
However this function of Messages can be turned Off.
This pic was created for something else but you can see the second line down is about setting the Status to Offline when the App is Quit.
This effectively stops the App doing the Listening.
Back to the Lifestream issue.
I am not sure what triggers the Lifestream to be set up.
I used a Search on the Lifestream site for my main AIM Name (which I can set the Lifestream to Privacy > No-one) and for my @me.com one which I cannot log in to the AIM settings site.
I cannot see anything returned in either case.
I also tried when Logged in under my main AIM name and got this form my @me.com ID
I think that when AOL/AIM started Lifestream all those people that had AIM and AIM valid Screen Names were included in Lifestream.
It may now be different and you may have to sign up for it.
There seems to be a set up page.
It would seem that my @me.com ID and @icloud.com ID have not been set up for Lifestream where as my AIM account (Main AIM Name as I call it) was set up in the beginning.
I am afraid I don't have any clearer information than that on this part of your enquiry.
