SOA composite application best practice

Hi All,
We are running SOA Suite 11g. One of my colleagues said that we should always have a mediator in our composite applications instead of just exposing the BPEL Process as a SOAP service. Is this a correct statement? If so why is that good practice. Still trying to grasp the concepts and best practices for SOA so any information is greatly appreciated.
Thanks,
S

if you place a mediator in between them, you can change the bpel interface without having to change your composite soap interface
that's one thing which could be a best practice

Naming of my SOA Composite Application ? (EBF, ABCS...)

Hi all
I have created a SOA composite application that uses a dbAdapter to poll data from a database and that processes these data in a BPEL process.
The BPEL process transforms the data, then calls other dbAdapters to perform business tasks.
I'd like to be sure of the naming of the SOA composite application.
Should I name it with suffix "EBF" ? Something like "MyServiceEBF" ?
Thanks.

Hi,
You can use the documents bellow as guideline for naming conventions... However, naming convention can variate from company to company and there's no global rule or established general practice for composite application names...

Error While executing the SOA Composite application.

Hi Gurus,
I have recently installed the VM box "oel6-64bit-soasuite-11gr1-ps6-otn.ovi" for Learning the SOA and also gone through the SOA Oracle training so i have the lab exercise documents with me. So i was trying to follow the steps mentioned in the training document for chapter 5 (CCValidate) for credit card Validation in which SOA composite application uses the DB adapter to query the DA and return the Credit card status.
I'm using the JNDI as "eis/DB/SOADemo" and when i looked in the Admin Console i can see the DB adapter status is OK .
Domain Structure --> dev_soasuite --> Services --> Data Source --> I dont See the eis/DB/SOADemo listed.
also tried to add the eis/DB/SOADemo in data Source but thorws Java exception saying already exists.
Domain Structure --> Environment --> Servers --> View JNDI Tree --> I can see the above mentioend JNDI i.e. eis/DB/SOADemo.
Please let me know what is wrong and how i can get rid of it.
But when i deployed the SOA Composite application on Server and tested the same it is throwing exception as below
ava.lang.Exception: oracle.sysman.emSDK.webservices.wsdlapi.SoapTestException: Client received SOAP Fault from server : Exception occured when binding was invoked. Exception occured during invocation of JCA binding: "JCA Binding execute of Reference operation 'CreditCardDBServiceSelect' failed due to: DBReadInteractionSpec Execute Failed Exception.

> Domain Structure --> dev_soasuite --> Services --> Data Source --> I dont See the eis/DB/SOADemo listed.
Do you see jdbc/SOADataSource? If you go to connection pool, what are the connection parameters: host, database, user, etc? I bet the user is not SOADEMO there...
> When i queried it from the database using the user SOADEMO it returns data
What other parameters are you using to query the database? host, database, etc... Are them the SAME you see on the connection pool above? I bet something is different...
Hope this helps...

Hi,
I'm not talking about the add. if you select a product ....

How SOA composite Application Instance ID gets generated

Hi,
While I was working with one of my minor SOA project, I noticed one thing that the SOA composite application instance IDs are not generated in a particular sequence. The numbers specified as Instance ID are random. Sometimes there is a difference of hundreds, sometimes of thousands and other times of difference reaches in lakhs. I am unable to understand the Procedure how these Instance IDs get generated when we deploy our project.
Thanks & Regards
Parul Nagpal

Instance Id's (CIKEY) are generated from ID_RANGE table, every call to this table returns a different range of sequences. Instance Ids will not collide across different Managed servers. Instance ID gets refreshed with each server restarts and is not equal across nodes or after restart.
Information to configure this range can be found in 12.2.9 InstanceKeyBlockSize in the Oracle BPEL Process Manager Performance Tuning Guide.
Reference : http://docs.oracle.com/cd/E14571_01/core.1111/e10108/bpel.htm
Reference :CIKEY or Instance ID generation for composites in SOA Suite 11.1.1.4 (Doc ID 1312037.1)

Slow starup of Java application - best practices for fine tuning JVM?

We are having problems with a java application, which takes a long time to startup.
In order to understand our question we better start with some background info. You will find the question(s) after that.
Background:
The setup is as follows:
In a client-server solution we have a win xp, fat client running java 1.6.0.18.
(Sun JRE). The fat client containt a lot of GUI, and connects to a server for DB access. Client machines are typical 1 to 3 years old (there are problems even on brand new machines). They have the client version of JRE - standard edition installed (Java SE 6 update 10 or better) Pretty much usual stuff so far.
We have done a lot of profiling on the client code, and yes we have found parts of our own Java code that needs improving. we are all over this. Server side seems ok with good response times. So far, we havent found anything about shaky net connections or endless loops in the java client code or similiar.
Still, things are not good. Starting the application takes a long time. too long.
There are many complicating factors, but here is what we think we have observed:
There is a problem with cold vs. varm starts of the application. Apparently, after a reboot of the client PC - things are really, really bad - and it takes (sometimes) up to 30-40 secs to start the application (until we arrive at the start GUI in our app).
If we run our application, close it down, and then restart
without rebooting, things are a lot better. It then usually takes
something like 15 - 20 sec. which is "acceptable". Not good, but acceptable,
Any ideas why?
I have googled it, and some links seems to suggest that the reason could be disk cache. Where vital jar are already in disk cache on th warm start? Does that make any sense? Virus scanners presumable runs in both cases.
People still think that 15 - 20 sec in start up on the warm start is an awful long time, even though there is a lot, a lot, of functionality in the application.
We got a suggestion to use IBMs JRE - as it can do some tricks (not sure what) our SUN JRE cant do concerning the warm and cold start problem. But thats is not an option for us. And noone has come up with any really good suggestions with the SUN JRE so far?
On the Java Quick Starter (JQS) -
improves initial startup time for most java applets and applications.
Which might be helpful? People on the internet seem more interested
in uninstalling the thing than actually installing it though?
And it seems very proprietary, where we cant give our Jar files to it?
We could obviously try to "hide" the problem in some way and make it "seem" quicker. Where perceived performance can be just as good as actual performance. But it does seem a bad solution. So for the cold start we will probably try reading the jar files and thereby have them in disk cache before startup of our application. And see if that helps us.
Still, ok the cold start is the real killer, but warm start isn't exactly wonderfull either.
People have suggested that we read more on the JVM and performance.
java.sun.com.javase/technologies/performance.jsp
java.sun.com.docs/hotspot/gc5.0/gc_tuning_5.html
the use of JVM flags "-Xms" "-Xmx" etc etc.
And here comes the question .. da da ...
Concerning various suggested reading material.
it is very much appreciated - but we will like to ask people here - if it is possibe to get more specific pointers. to where the gold might be buried.
I.e. in a an ideal world we would have time to read and understand all of these documents in depth. However, in this less than ideal world we are also doing a lot of very timeconsuming profiling in our own java code.
E.g. java garbage collection is is a huge subject - and JVm settings also. Sure, in the end we will probably have to do this all very thoroughly. But for now we are hoping for some heuristics on what other people are doing when facing a problem like ours..?
Young generation, large memory pages, garbage collection threads ect. all sounds interesting - but what would you start with?
If you don't have info to decide - what kind of profiling would you be running and then adjust what JVM setting in your trials?
In this pressed for time scenario. Ignorance is not bliss. But makes it hard to pinpoint the or those JVM parameters to adjust. So some good pointers from experienced JVM "configurators" will be much appreciated!
Actually, If we can establish that finetuning of these parameters is a good idea, it will certainly also be much easier to allocate the time for doing so. - reading, experimenting etc. in our project.
So, All in all , what kinds of performance improvements can we hope for? 5 out of 20 secs on the warm start? Or is it 10 % nitpicking? Whats the ball park figure for what we can hope to achieve here given our setup? What do you think based on above?
Maybe someone out there have done some finetuning of JVM parameters in a similiar PC environments like, with similiar fat clients...? Finetuning so and so - gave 5 secs. So start your work with these one-two parameters?
Something like that - some best practices? Thats what we are hoping for.
best wishes

Thanks for helpful answer from both you and kajbj.
The app doesn't use shared network drives.
What are you doing between main starts to get executed and the UI is
displayed?
Basicly, Calculating what to show in the UI. Accessing server - not so much, there are some reads from a cache, but the profiling doesnt indicate that it should be a problem. Sure, I could shift the startup time to some other slot, but sofar I havent found a place where the end-user wouldnt be annoyed.> Caching of something would seem most obvious. Normal VM stuff >seems unlikely. With profiling i basicly find that ''everything'' takes a lot longer in the cold start scenario. Some of our local java methods are going to be rewritten following our review. But what else can be tuned?You guys dont think the Java Quick Start approach, with more jars in disk cache will give something? And how should that be done/ what does people do?I.e. For the class loader I read something about
1.Bootstrap class loader
2.Extensions class loader
3.System class loader
and is wondering if this has something to do with the cold start problem?
The extensions class loader loads the code in the extensions directories (<JAVA_HOME>/lib/ext
So, we should move app classes to ext? Put them in one jar file? (We have many). Best practice about that?
Otherwise it seems to me that it must be about finetuning the JVM?
I imagine that it is a question about:
1. the right heap size
2. the right garbage collection scheme
Googling heap size for XP
CHE22 writes:
You are right; -Xms1600M works well, but -Xms1700M bombs
Thats one best practice or what?
On garbage collection, there are numerous posts, and much "masters of Java black art" IMHO, And according to profiling GC is not really that much of a problem anyway? Still,
Based on my description I was hoping for a short reply like "try setting these two parameters on your xp box, it worked for me" ...or something like that. With no takers on that one, I fear people are saying that there is nothing to be gained there?
we read:
[ -Xmx3800m -Xms3800m
Configures a large Java heap to take advantage of the large memory system.
-Xmn2g
Configures a large heap for the young generation (which can be collected in parallel), again taking advantage of the large memory system. It helps prevent short lived objects from being prematurely promoted to the old generation, where garbage collection is more expensive.
Unless you have problems with pauses, try granting as much memory as possible to the virtual machine. The default size (64MB) is often too small.
Setting -Xms and -Xmx to the same value increases predictability by removing the most important sizing decision from the virtual machine. On the other hand, the virtual machine can't compensate if you make a poor choice.
The -XX:+AggressiveHeap+ option inspects the machine resources (size of memory and number of processors) and attempts to set various parameters to be optimal for long-running, memory allocation-intensive jobs]
So is Setting -Xms and -Xmx and -XX:AggressiveHeap
best practice? What kind of performance improvement should we expect?
Concerning JIT:
I read this one
[the impact of the JIT compiler is obvious on the graph: at startup the time taken is around 500us for the first few values, then quickly drops to 130us, before falling again to 70us, where it stays for 30 minutes,
for this specific issue, I greatly improved my performances by configuring another VM argument: I set -XX:CompileThreshold=50]
The size of the cache can be changed with
-Xmaxjitcodesize
This sounds like you should do something with JIT args, but reading
// We disable the JIT during toolkit initialization. This
// tends to touch lots of classes that aren't needed again
// later and therefore JITing is counter-productiive.
java.lang.Compiler.disable();
However, finding
the sweet spots for compilation thresholds has been tricky, so we're
still experimenting with the recompilation policy. Work on it
continues.
sounds like there is no such straigth forward path, it all depends...
Ok, its good, when
[Small methods that can be more easily analyzed, optimized, and inlined where necessary (and not inlined where not necessary). Clearly delineated uses of data so that usage patterns and lifetimes are apparent. ]
but when I read this:
[The virtual machine is responsible for byte code execution, storage allocation, thread synchronization, etc. Running with the virtual machine are native code libraries that handle input and output through the operating system, especially graphics operations through the window system. Programs that spend significant portions of their time in those native code libraries will not see their performance on HotSpot improved as much as programs that spend most of their time executing byte codes.]
I have the feeling that we might not able to improve performance that way?
Any comments?
otherwise i was wondering about
-XX:CompileThreshold=50 -Xmaxjitcodesize (large, how large?)
Somehow, we still feel that someone out there should have experienced similiar problems? But obviously there is no guarantee that the someone should surf by here!
In c++ we used to just write everything ourselves. Here it does seem to be a question about the right use of other peoples stuff?
Where you are kind of hoping for a shortcut, so you dont have to read endless number of documents, but can find a short document that actually addresses your problem ... well.

Large ADF Applications - Best Practice

Hi
We have a single ADF project (one model, one view/controller) with the following model components:
68 AMs
387 VOs
175 EOs
This project is ever expanding, and we are suffering some well-known performance problems when open JDeveloper or open the view/controller project.
Are there any best-practice guidelines on how to structure your ADF projects?
e.g. what is the maximum recommended number of AMs/VOs/EOs in a single project?
We have kept everything in a single project after some advice from Oracle to help us to re-use common modules easily.
We use JDeveloper v10.1.3 and use JHeadstart v10.1.3 SU 1 to generate our view/controller layer, using multiple faces-config files.
Thanks
Denis

Hi Denis,
We have exactly the same problem in expanding our application but we have a single AM and less EOs, VOs than you right now. There are some threads discussing this issue but I haven't found a complete and standard solution yet. The only thing I know is that almost every thing can be segmented in ADF like projects, application module, faces-config.xml, ...
Another thing which is very important is that segmenting an application is a tradeoff, it has some advantaes but problems in SCM, security, ...
S/\EE|)

SOA OSB Deployment best practices in Production environment.

Hi All
I just wanted to know the best practices followed in production environment for deploying OSB and SOA Code. As you are aware that both require libraries from either (Jdev or SOA Suite) and (OEPE and OSB)? Should one rip the libraries and package them with the ANT scripts (I am not sure but SOA would require its internal ANT scripts and lot of libraries to be bundled, OSB requires only a few OEPE and OSB libraries) or we simply use the below:
1) Use the production run time (SOA Server and OSB Server) to build and deploy the code. OEPE would not be present here, so we would just have to deploy the already created sbconfig.jar (We would build this in a local environment where OEPE and OSB would be installed). The code is checked out from a repository and transferred to this linux machine.
2) Use a windows machine (which has access to prod environment) and have Jdeveloper, OEPE and OSB installed to build\deploy the code to production server. The code is checked out from a repository.
Please let us know your personal experiences with the deployment in PROD. Thanks a lot!

There are two approaches for deployment of OSB and SOA code.
1. Use a machine specifically for build and deployment which will have access to all production environments (where deployment needs to be done). Install all the required software (oepe, OSB etc..) and use remote deployment for deploying the code.
2. Bundle all the build and deployment related libraries and ship them as a deployment package on the target server and proceed with the deployment.
Most commonly followed approach is approach#1.

Vivek

Grid Control and SOA suite monitoring best practice

Hi there,
I’m trying to monitor a SOA implementation on Grid Control.
Are there some best practices about it?
Thanks,
Nisti
Edited by: rnisti on 12-Nov-2009 9:34 AM

If they use it to access and monitor the database without making any other changes, then it should be fine. But if they start scheduling stuff like oradba mentioned above, then that is where they will clash.
You do not want a situation where different jobs are running on the same database from different setups by different team (cron, dbcontrol, dbms_job, grid control).
Just remember their will be aditional resource usage on the database/server to have both running and the Grid Control Repository cannot be in the same database as the db console repository.

Hotfix Application Best Practices

I have a twofer with regards to applying a hotfix. We deployed Config Manager 2012 RTM, upgraded to SP1, and then upgraded to R2. We have never applied a hotfix or CU before, so there is a bit of mysteriousness with regards to what the best practices are.
We are applying hotfix 2910552 to address slow imaging speeds. These questions are pretty basic but I wanted to get some informed opinions.
What is the best rollback procedure in the event of problems? I consider the hotifx a low risk but there is some concern from some others above me. We are planning on taking snapshots of the 3 site servers and the DB server in our hierarchy, but not the
DPs. Does this seem sound or is there a better technique?
How essential is it to update the clients in our environment in a timely fashion, or at all? I am going to have the packages created, but I did not know if I should deploy them immediately or not. Our server group has some concerns about applying the patch
to the config manager clients on our servers during our patching windows.
Any insight is appreciated. Thanks!
Bryan

There's more risk in taking snapshots as they are completely and explicitly unsupported and almost certainly would cause issues particularly since your DB is separate from your site server.
Rollback is simply uninstalling the hotfix. That hotfix addresses a very niche issue that only manifests itself during OSD, thus, it's only important roll it out to clients before you reimage them in a refresh scenario. An alternative rollback is simply
reinstalling the site and restoring your DB. This sounds painful and while it would take a bit of time, it's actually rather painless and works quite well.
This all begs the question though, you really should just do CU3. There are tons of other meaningful and impactful fixes in the CUs that will improve the overall stability and even functionality of the site and clients.
Concerns for applying hotfixes should be addressed by performing the update in a lab first. There is no other way to comfort risk averse folks except by showing them that it works. Additionally, you put forth evidence from the community that CU application
to ConfigMgr is almost always smooth and uneventful. Can something go wrong? Of course. I could get hit by lightning sitting in my chair but that doesn't mean I stay in bed all day.

SOA System Testing on SOA Suite. Best Practices and approaches needed.

Hi,
New to this Forum and sorry if I landed at wrong place. We need to perform System/Functional testing for applications deployed on Oracle SOA Suite.
SOAP UI helps us in many ways.
But scenarios below being considered, we need your expertise to help us in this effort:
Services may be of various complexities...Eg:
1. A service operation may be of kind where we send a request and not receive response.
2. Service of type where we send request and cannot wait for response bcoz of service being in Asynchronous nature.
3. Request sent and we get batch of responses and also a vice-versa scenario.
Unit Testing for above scenarios can be done using JDeveloper based BPEL Test Framework. However, our focus is with respect to System Testing.
Any Open-source Testing tools for Web Services or proprietary tools that can do this would be of help.
Please note that we have evaluated and find that HP Service Test Tool helps in almost all above scenarios. However, looking for all possible alternatives and best approaches.
Your Advice is highly appreciated.
Best Regards,
Chaitanya

SOA Composite Application Deployment Failed

I have created a composite SOA application and trying to deploy it on WLS. I have created a connection to the Application Server MyAppServerConnection. I right click the project name and point to Deploy, it gives the webservice name "validationForCC". it does not give anything further. It should give Deploy>to>MyAppServerConnection
I click the application name"validationForCC" and it opens the Deployment Configuration window. It asks for attach SOA Configuration Plan. Im not sure which Plan file to attach, JMS Plan or DBPlan. I try without selecting any.
In JDeveloper the moment it gives message of successful compilation but when i test it on EM console, it fails to run.

These questions don't look like they are directly related to JMS, and seem more related to the tooling that you're using. I think you should try posting to a forum that's familiar with your environment. Perhaps you can choose a forum under "SOA & Process Management". Here's a link to the forum listing:

Web application best practice...

I'm creating a web site with heaps of Flash stuff on it. I'd
like it to load plenty of information from a database server and
save plenty of information back again. It's not a vast amount of
information by the way - i don't need to load video clips and
things, but there will be loads of different flash resources on the
site and so plenty of different occasions when there'll need to be
some loading and saving going on.
So to the question - what's best to use?
1) LoadVars? (or XML Object) - I'm pegging this option
together as I can see that loading some of the info in XML format
from say an ASP page could be a good idea
2) Web services? I don't know much about webservices, but
plenty of big companies seem to be offering them out - google,
yahoo and flickr for example (- but dya reckon they use them
themselves?) I realise i'd have to learn something a bit different
like .net (so maybe VB.net or c# or something any opinions about
which to go for there too??) or maybe perl or python or
something...
3) Flash Remoting? I have bad feelings about this one - i
don't want to pay for extra stuff if it doesn't do much for me -
and i understand that with this one i'll still need my server side
application anyway - so it makes me wonder what the point is? And
I've also heard that the latest flash version doesn't really
support it very welll.....
So does anyone have any thoughts? I'd love to hear some
opinions... I DO care about performance and I DO care about how
fussy and complicated the programming will be. My gut reaction is
that web services are the way to go, because to my naive mind they
seem like they'll be simpler to code and potentially have less bugs
and therefore be more reliable. But then I'm not trusting my naive
mind, I'm asking you clever forum types instead!
Best Wishes,
Neil

I don't think I can offer any definitive advice. Partly
because it should be based on what your requirements are longer
term I guess, and (probably mostly) because I don't know that much
about it myself. I'll share what little I know.
For flash, in terms of my understanding remoting is the
fastest/most efficient means of communicating with a service you
expose on your server , and I'd assume its more scalable as an
approach longer term. There's the Adobe versions with Coldfusion
and, I think .net, but there are open source options e.g. AMFPHP as
well. I think that CS3/as3 will ultimately have no problems with
remoting - I read somewhere that although the remoting components
are not there now, flash cs3 can use flex non-visual components and
also somewhere else that the remoting components are not necessary
for remoting to be possible (but I guess they make it easier). I
have no idea whether either is true, but I'd be surprised if long
term flash cs3 can't do remoting as well as previous versions. The
amf encoding method that is used for remoting is more readily
accessible in as3 I think, so I can't see it being a problem.
There's another framework for a type of remoting based on
what I assume is some form of XML serialisation called XMLPC , but
I don't know much about it.
Both flash remoting and XMLRPC give you the ability to not
worry about how the data is translated and transferred between
flash client and server. You just deal with it in the native data
structures in a similar way to making function/method calls
locally. LoadVars is great if you just want to transfer name value
pairs...eg sets of variables, XML is great for transferring
structured representation of data. I've become more accustomed to
working with XML as it is and using it as a the basis for my data
in flash when I need to use it, which saves having customer
encoding/decoding functions to change the way its dealt with
locally. This is not always possible or convenient... but with
XPathAPI in as2 it is a little easier, and I'm looking forward to
using the new CS3 xml representation.
LoadVars and XML are also great and if you're starting out,
and are probably essential in terms of having them as an option
anyhow so may not be a bad option to begin with just so you're
familiar with them. I would suggest that you always know how to
work with these approaches and maybe they'll be enough for you for
now anyway .
I know nothing about SOAP or any other type of webservice.
Don't know if that helps.

Schema Design for Worklist Application - best practice?

Hello,
we are designing the Schema for a workflow application now. I'm wondering what kind of XML Schema would be best suited for the JSP generation of the Workflow Wizard.
So far I've found out with some tests (please correct me if I'm wrong):
- Only elements will be mapped to JSP fields, not attributes
- If elements have single-letter name, the field label will be eliminated totally in JSP (bug?!)
- For EVERY parent node, an HTML table is generated in the JSP containing all the simple nodes in the parent. If a parent node contains another parent node, both tables will be generated on the same level.
And I haven't found any way to create drop-down list or checkbox/radiobuttons out of the XSD definition (enumeration as element type).
I would really appreciate it if someone could share some experience in this area, many thanks in advance!
regards
ZHU Jia
