 Maximum Pool Size: 50
 Maximum Connections: 200
 Connection Timeout (msec.): 30
 Maximum Waiting Time (msec.): 60
5. Network connection (Ping EP and ERP) is OK.
 Ping <host> -l 65500 -t
6. Hosts and Service file is OK.
 We have DNS Server. It is ok too.
7. We are already settings for these values as below. (Note 316877).

Hi Experts,
I am having some issue with PO and ECC connectivity with data load from PO to ECC system via RFC connection
RFC is configured in PO , SOA -> Technical Configuration -> System Connections -> Provider Systems -> Connectivity as below

We are getting this error sporadically,
Do I have to do anything with the SLMG log on group for this RFC connection ?

Hi Imtiaz,
Thanks again for your reply.
gw/cpic_timeout is dynamic and I have increased to 40 from 20 , and gw/max_conn is already set to 4000.
To isolate the problem, I have also removed load balancing with the connection, now directly with CI only. This is production, so I have to wait till next data load.
I will update with the result
Thanks

Hi,
It seems that the SAP gateway host is deactivated or the TCP/IP port 33xx (where xx corresponds to the system number) is not open.
First try pinging <IP address>. If there is no reply, then Boot SAP Gateway host required.
Check whether the TCP/IP port 33xx is open (where xx corresponds to the system number) and start the SAP gateway
The TCP/IP port is also partially defined in the services file as an sapgw<SID> or sapgwxx entry (where xx corresponds to the system number). The services file is in the Windows directory or in WinNT/System32/drivers/etc.
Hope this helps.
Regards

I have strange errors in trace while starting Java stack (many of them, but reason always the same):
Connect to SAP gateway failed
Connect_PM TYPE=A ASHOST=localhost SYSNR=00 GWHOST=localhost GWSERV=sapgw00 PCS=1
LOCATION CPIC (TCP/IP) on local host with Unicode
ERROR partner '127.0.0.1:sapgw00' not reached
The problem is (I guess) that it tries to connect to localhost (and in RFC connection SAPJ2EE I have given hostname as aaabwd). Where and how change Java configuration to make it connect by default to ASHOST=aaabwd not localhost).
REgs,
FS
PS. Point will be rewarded!!

Try this

JCO Problem - (102) RFC_ERROR_COMMUNICATION/Group PUBLIC not found

Hi all,
I installed the u201CSAP NetWeaver 7.01 - ABAP Trial Versionu201D and the u201CEHP1 for SAP NetWeaver Composition Environment 7.1 - Preview Versionu201D on same machine (drive u201CDu201D) and both are working.
My intention is to learn WebDynpro accessing BAPIu2019s created by me (learning ABAP too) using RFCu2019s.
I just did it using JCou2019s but it was all configured.
The problem is that, I create the Dictionary JCo (META_DATA) but when I ping or test always return the errors below:
Ping: Failed to ping JCo destination 'ME_META_DATA'.
Test: com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=localhost GROUP=PUBLIC R3NAME=NSP MSSERV=sapmsNSP PCS=1 ERROR Group PUBLIC not found TIME Wed Jan 07 00:40:57 2009 RELEASE 711 COMPONENT LG VERSION 5 RC -6 MODULE lgxx.c LINE 4574 DETAIL LgIGroupX COUNTER 2
I created the Application JCo (MODEL_DATA) with success and it is working (Ping and Test).
Even using the existing SDN documentation /forums, it seems that something is missing, a parameter; a procedure how to configure a parameter; the sequence of actions or the need of re-start the instance or machine.
I u201Csupposeu201D that the problem may be at Stack ABAP. The group PUBLIC was created (SMLG), the services windows file is ok
If some one had success and have a step-by-step procedure or a good tip it will be very appreciated.
Thanks in advance.
Walmir Catunda

Hi Jason andd Walmir,
Its woking JCO connetion for Sneek Preview ABAP trial version 7.01. Once you setup the logon group, you must execute the program rsrzllg0_actual in the SE38 and next unchecked the FRCE_SAV and clicked on the execute button. then check your jco connection. it is working in the my case.
Thank you so much Jason!
I think you can close this thread.

JCO Exception(102)

hi folks,
when fetching data from an rfc func.mod from r/3 i get an exception:
JCO Exception(102) JCO_ERROR_COMMUNICATION no protocol: 01
does anyone has an idea what went wrong?
how to find easily answers to such errors?
one side-question:
i want to debug a webdynpro application, but the IDE says Server is not in DEBUG-Mode! Any Ideas where to customize that entry?
kind regards
oliver

To Debug,
You could activate the debugging from the NDS or by changing the server config file. Ideal way is to start the debugging from NDS using the J2EE engine view.
STEPS
1.Right Click on the server0 and choose "Enable Debugging of Process"

Hi Alberto,
CPIC is a type of user (Communication..) used for certain calls.
Has your BASIS team applied all the patches and related system settings?
SOrry, I do not remember the exact answer to the issue.
But I do remember that it is a system setup issue.
Good luck, BB

Venki,
I guess you are not an XI person.
You can contact any XI/PI person in your organization and tell them to do mention changes in Integraion Buider: Configuration. And then check.

Hi Gobinath,
      Check your SLD configuration. Looks like there is some problem with the parameters specified for your logical system..
     The exception says it is not able to locate the host.
Thanks

(102) RFC_ERROR_COMMUNICATION: Connect to message server host failed

Hello,
I'm almost giving up on this...I've been messing with this for too long now...

I try to get the flightlist demo to work. I've put in "sapmsANB         3600/tcp" in services file locally in my machine (I'm using Sneak Preview SP11).
I've also done everything in "/people/sugree.phatanapherom/blog/2005/08/14/configuring-sld-in-sneak-preview-sap-netweaver-04-sneak
I've done everything possible to get this to work, but no luck.
What is wrong here?, please help

Now I've put in "193.183.156.17     PetJoh     PetJoh.afab.local" in Hosts -> rebooted -> but still can't ping exts0002 (or the fully resolved name to it) I can't ping the actual IP nr either.
I can, however use JCO java code like:

               System.out.println(mConnection.getAttributes());
               mConnection.disconnect();
          } catch (Exception ex) {
               ex.printStackTrace();
               System.exit(1);
     public static     void main (String args[]) {
               R3Connect app =     new     R3Connect();
This works perfectly fine to connect, Why doesn't SLD?

(102) RFC_ERROR_COMMUNICATION: Connect to SAP gateway failed

hello everybody,
i have a problem in all my receiver RFC comunication Channel (PI 7.1).
Every night we resart the R3 system where CC need to comunicate.
On the morning all Receiver RFC CC don't work and i have the follow error:
Receiver channel 'CC_SAP_RFC_LOOKUP' for party '', service 'BS_ECD'
Error can not instantiate RfcPool caused by:

I need stop and start the CC.
I cannot propose to customer to stop and start CC every morning.
How can i solve this problem?
thanks
Alex

Hi,
As a workaround you can plan the availability of your RFC channels according to the downtime of R3 system.
The channels will be stopped and started automatically in this case. take a look here,
http://help.sap.com/saphelp_nwpi71/helpdata/en/46/ad6cfeb5492a86e10000000a1553f6/content.htm
regarding the problem, did you see Q25 of this note

Hi Gregor,
The Messages i am getting i.e. "Session 1: Special character for 'empty field' is /" is one of the GUI information messages that the standard SAP uplaod program is popping.
i want to suppress these messages when calling them through an external system so that they can be called in background.
The standard program is using the batch input method.
Thanks and Regards
