Hi everyone,
I am making a RFC call from a Web Dynrpo Application developed in 04s Environement.
It appears to work fine on my development system.
But when tested on Staging Servers with large number of concurrent users, it gives me the following error
Could not create JCOClientConnection for logical System: 'JCO_CIP_RFC_MODELDATA' - Model: 'class com..cip.modeldc.model.orgtreemodel.' ...
I am using the following code to disconnect after each and every R/3 calls:
try
{
//model calls made here
} catch (RuntimeException e) {
...
}finally{
wdContext.current<context>Element().
modelObject().modelInstance().disconnectIfAlive();
}
Please help me fix this problem
Thanx,
Kunal
Hi,
Check the JCo Pool Configuration settings of your JCO Destination. This message normally comes when the maximum connections has been reached. Increase the "Maximum Connections" to some number depending on the usage. A good habit is to disconnect the jco connection after executing the same in your webdynpro code if you don't want it to be synchronous.
<ModelName>.modelInstance().disconnectIfAlive()

Hi,
This error means that either your test user is not defined/ locked in the backend or you have JCO configurations problem,
Have you tested the JCO connections?
