Hello

If creation of iview is taking more than normal time, then the issue can be investigated through thread dumps on J2EE Instances. You need to reproduce the issue and capture 4-5 thread dumps at an interval of 30 secs. If possible, shut down all server nodes except one. This will ensure creation request going to only running server node. You may refer sap note sap note 710154. If you can't analyze the thread dump, you can upload with the thread and I will have a look.

Hello Vanitha,

I am talking about the screenshpot provided by you above where you have marked only RFC trace , please mark other traces for that user ie. SQL Trace, Enqueue Trace and Table Buffer trace, it would somewhat give more idea.

Hi Experts,

Please find the following code, is there any  performance issue.

//Execute List BAPI

  ZRFC name_Input input = new Z RFC nameInput();

  wdContext.nodeZRFC name_Input().bind(input);

  input.setflag("F");

  Zinternal_Input Details = new Zinternal_Input();

  //Details.setAttr1(wdContext.currentContextElement().getEmpid);

  //Details.setAttr2();

input.setNodeinRFC(Details);

  wdThis.wdGetCompController().executeZRFC name();

is there any root cause to get performance issue in the application.

Please help on this issue.

Hi Vanitha,

I do not see any issues in the above code.

Just to confirm, did you test the FM / BAPI standalone directly in R/3? Is it taking the same time there also?

If the problem arises only when you make the RFC call from Portal to R/3, put an external break point in R/3 and debug and analyse the issue.

Hi Anurag,

Thank you for your reply, could you please let me know how can i test the FM/BAPI standalone directly in R/3.

We have to find the root cause of this issue, so after click on the create button ,two RFC's are triggering when put an external break point in the two RFC's.

Please help me on this issue.

Hi Vanitha,

Just execute the remote enabled FMs directly in R/3 system. Set the required data in the attributes and execute the FM and check how much time each FM is taking for execution.

If you do not find any performance issues in the execution of FMs directly in R/3 system, then put the breakpoints on each FMs that are called on click of "Create" button and then try to find out the issue.

Hi Vanita,

Please use HTTPWatch to see why your request is getting late response. It might be that you get late response from back end system and due to that problem occurs.

Hi Ravi Maheshwari,

Hi Vanitha,

If don't have authorization to install software. Follow below:

1. Preview iView by opening iView from content administration and analyse the response. Is it taking same time, less time or more time?

2. Go to system landscape under system administration and test the connection, analyse how much time it is taking for successful connection.

If you have admin access then you can record the log by going to http://host:port/tshw.

Perform the above and post the result.

Hi Ravi Maheshwari,

Sorry for the delay reply, i have tested the following cases.

1)  if we click on the preview of the iview ,then it will open same time (3 min time).

2) what can i test the connnection under system landscape.

3) how can i record the log .

Please help me ,its very useful to me.

Hello Vanitha,

Ask the Basis Guy to activate trace for the User Id that your are using to test.

The trace will give an idea on the data load issue and also you can check in SM50 transaction(normally basis guy have) at the time you are executing the application.
