Problem with JCo Connection Pool

[Former Member]

Hi,

I have a problem with using an RFC Model in my WebApplication. So sometimes the access to the function block works, and sometimes it doesn't work. Now I know, that there is a problem with the connection pool. Look at this message:

com.sap.mw.jco.JCO$Exception: (106) JCO_ERROR_RESOURCE: Connection pool WD_X24_MODELDATA_DEST_CPIC_REKTO_DE_useDefinedUser is exhausted. The current pool size limit (max connections) is 10 connections.

So it looks like a problem with closing the JCo Connections after using. Do know where the problem is? Because I'm using many other function blocks with no problems.

Hello,

You need to increase the pool size via Visual Administrator.

Server 0 -> Services -> JCO RFC Connections.

Change the pool size from there. I believe a restart is in order.
