AOP advice execution sequence

[akhilesh laddha]

Hi All,

I would like to get clarify my self about AOP advice execution sequence along with the application code. Does AOP advice execute in parallel with application methods for that cross cut defines?

 

For example

Application method - foo()  (for cross cut define)

Takes execution time T1

Advice – fooAdvice() takes t1 time

 

If AOP advice runs sequentially with application code then additional performance hit because of advice code execution.

 

Total time will be – T1 +t1

 

From my understanding it runs in parallel therefore it takes time equal to whichever is higher for ex – T1

 

Please correct my understanding

 

Thanks

Akhilesh

no it runs in the same code path - as if you wrote it
this said it is easy to have your advice produce an async task that
will be consumed by some thread queue if you want
it is all up to you

Hi,
 
How to implement asynchronous aspect ?
Can we get any sample if available.
 
Any help is appreciated.
 

Thanks and Regards,
Lalithamba.

I think there is nothing AOP-specific to it. Just launch your task in a separate thread using standard java threading techniques.

Hi All,

Is this the only mechanism to run advice in parallel with the
application methods for that cross cut defines?

Or, any other option comes inherently with AOP framework to do the same.  Please do let me know.

[akhilesh laddha]

Alex,

I have some doubt.  Because, attached document section 5, 6 and 7 describes that AOP advice run in parallel with the application code.

 

In this url http://www.sdtimes.com/editorial/opinion-20020101-01.html article explain in the same line.

 

Still, my understanding is not clarified, because your reply defer from the article.

 

Is that all Java AOP framework inherently not support parallel execution of advice with the application code?

 

Please let me know.

 

Thanks

Alex,

I would like to know, what would be the right approach to bring the parallel execution of advice functionality up in the solution.

Should I tweak the framework code or own solution (means create a thread in advice and execute localize concerns code in run method)?

 

Code snippet to add in own solution---

 

MyAdvice()

{

     MyConcerns concerns = MyConcerns ();

     new Thread(concerns).start();

}

 

 

 

------------------

Class MyConcerns ()

{

   public void run()

  {

    System.out.println("Log info");

  }

}

 

-----------------------------------

 

Note - If we need to tweak in the framework code then where I need to do. Please do let me know.

 

Thanks
Akhilesh

Hi Alex,

Below is the message which my manager had posted and I guess since he was not a registered user, the question did not get posted.

==========================================================================================================

Hi Alexandre,

I was following your mail chain and would like to put in a word of thanks about the guidance provided by you to our team.

A related two cents from me: I always felt AOP is a technology-concept implemented in specific ways for relevant frameworks. Now it is a different question all-together that a particular AOP-framework may not have features to support parallel processing but inherently AOP should be used for infrastructural capabilities which can be spawned via cross-cuts - I guess that is the core strength of AOP than just using it so that the piece gets executed in the same code-path.

Thanks,
Ritwik

Thanks and Regards,
Lalithamba.

Hi,

I am using Aspectwerkz to pointcut a standalone CORBA application which is running under naming service TAO in LINUX.

I have the following files :

Hello.idl
HelloClient.java
HelloServer.java


Now I execute the idl file using idlj utility of Java as follows :
==============================================
idlj -fall Hello.idl (this creates the stubs)

Compile the Client and Server file :
========================
javac HelloClient.java HelloApp/*.java
javac HelloServer.java HelloApp/*.java

set ASPECTWERKZ_HOME=D:\aspectwerkz-2.0

======================================================================

Now the naming service is running on linux.

I run HelloServer as follows :

java -Xbootclasspath/p:.:/opt/ALNA/bin/avalon-framework-4.1.5.jar:/opt/ALNA/bin/jacorb.jar:/opt/ALNA/bin/logkit-1.2.jar: -DORBInitRef.NameService=corbaloc:iiop:10.116.69.123:23000/NameService HelloServer

This shows : HelloServer ready and waiting ...

Next I am running HelloClient using aspectwerkz as :

/opt/aspectwerkz/bin/aspectwerkz -javaagent:/opt/eprofiler/Hello/eProfiler.jar -cp /opt/eprofiler/Hello/eProfiler.jar:/opt/eprofiler/Hello/aopfile.jar -Xbootclasspath/p:.:/opt/eprofiler/Hello/aopfile.jar:/opt/eprofiler/Hello:/opt/eprofiler/Hello/eProfiler.jar:/opt/ALNA/bin/avalon-framework-4.1.5.jar:/opt/ALNA/bin/jacorb.jar:/opt/ALNA/bin/logkit-1.2.jar:/opt/aspectwerkz/lib/aspectwerkz-core-2.0.jar:/opt/aspectwerkz/lib/aspectwerkz-2.0.jar: -DORBInitRef.NameService=corbaloc:iiop:10.116.69.123:23000/NameService HelloClient

After I run this, the application is not getting cross-cut.  Only the SOP of the program is getting printed.  My thought is aop.xml is not getting recognised.
aop.xml is present in META-INF directory and also I have placed it in aopfile.jar which just has META-INF directory with aop.xml file in it.

Any help in recognising the aop.xml is appreciated.

Thanks in advance.






Thanks and Regards,

Hello,

 

In the below scenario,  Once I run the client, the aop.xml gets recognsied by -Daspectwerkz.definition.file=path/aop.xml but the application is not getting pointcut.  Any clues why ?

Thanks and Regards,
Lalithamba.

Hi,

Pl reply as this is very urgent !

Environment : HP Unix
JDK - 1.3.1

I am trying to run a sample standalone java application in HP Unix using aspectwerkz as below :

===============================================
export ASPECTWERKZ_HOME=/home/patnipb/bv1to1_var/backend_services/aspectwerkz
echo $ASPECTWERKZ_HOME
/home/patnipb/bv1to1_var/backend_services/aspectwerkz/bin/aspectwerkz -Xbootclasspath/p:/home/patnipb/bv1to1_var/backend_services/enhanced.jar -Xbootclasspath/a:/home/patnipb/bv1to1_var/backend_services/aspectwerkz/lib/aspectwerkz-2.0.jar:/home/patnipb/bv1to1_var/backend_services/aspectwerkz/lib/piccolo-1.03.jar:/home/patnipb/bv1to1_var/backend_services/aspectwerkz/lib/dom4j-1.4.jar:/home/patnipb/bv1to1_var/backend_services/aspectwerkz/lib/jrexx-1.1.1.jar:/home/patnipb/bv1to1_var/backend_services/aspectwerkz/lib/trove-1.0.2.jar:/home/patnipb/eprofilerstandalone/eProfiler.jar -Daspectwerkz.definition.file=/home/patnipb/eprofiler_standalone/LeakExample/aop.xml -Daspectwerkz.transform.verbose=true -cp  /home/patnipb/eprofilerstandalone/eProfiler.jar:/home/patnipb/eprofiler_standalone/LeakExample/classes demos.memory.leakexample.LeakExample
