JCO$Exception: (102) RFC_ERROR_COMMUNICATION: CPIC-CALL: 'SAP_CMACCPTP'

[Former Member]

We are testing a 3-tier server architecture with imoproved firewall rules. -> new serber/network environment

RCF/BAPI call (application server to SAP) is ok.

Additionally we establish establishes/register a listener (RFCServer) from application-server at SAP through the JCO.Server functionality.

The listener seems to be up. But after about 5 minutes there takes place the following:

com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: CPIC-CALL: 'SAP_CMACCPTP'

LOCATION CPIC (TCP/IP) on local host

ERROR internal error

TIME Tue Sep 20 14:25:28 2005

RELEASE 620

COMPONENT NI (network interface)

VERSION 36

RC -1

COUNTER 1503

On SAP side we recognise the left open connection:

entry: 305

state: CONNECTED

system-type: REGISTER_TP

long tp: <our server name>

hostaddr [0]: <our server ip>

connect: Tue Sep 14:20:34 2005

last request: Tue Sep 14:20:34 2005

accept info: EINFO PING CONN_ERINFO

register status: WAITING

Every 5 minutes this happens again and increases the number of open connections on SAP server.

As this runs on production without problems, we suppose that there have to be opened further services/ports between our server and SAP. Or the test SAP server is not confiured as needed.

Any hint on a blocked service?

Hi Michael,

seems to be quite some time ago that this issue occured - had it been resolved ?

Looks like we are facing exactly the same issue

Hi,

I am also facing a similar kind of problem. The RFC server is created using JCO and is perfectly running in production. But when we setup a new testing environment, sometimes we are getting error and when we restart the RFC server the jobs start working.

The exact problem we are facing is we are running lot many jobs created in BW to tarnsfer data from SAP to an application server using these RFCs, the jobs are getting failed with "Communication Failure" error message in SAP and we need to restartt the RFC sever around 10 to 15 times a day for each job for getting all the jobs to success. And when we restart the RFC server and start the BW job again the job will run succesfuly. Can anyone please tell me what is causing this failure and help me out to solve this problem.

Here is the error we are getting:

INFO | jvm 1 | 2008/08/13 01:08:17 | Exception in server server@servername:

I am basicaly a Java developer and bit new to SAP. Any help for solving this problem will be highly appreciated.

Thanks,
