JCO Connection Error---URGENT!!!

[Former Member]

Hi

I created JCO connections to a sap server. The SLD was good and ok. However, from the JCO I am getting this error.

Please let me know <b>what is the solution to fix them.</b>

Hi Manish,

-Is it correct if Gateway host is the name of Exchange Infrastructure server,webas ?

-Is it correct that i choose "_SLD_RFC" in the part of data correction programs?

Thank you

Hi

Check if your message server is mentioned properly in your SLD. Also ensure that you have added that entry in the services file of windows nt. If you log in to your ABAP system at the right hand bottom , you would find a 3 letter caption. Just go to your services file and say

sapms<the 3 letter name> . Press a tab and then enter the port number as 36<instance number>. If instance number is 01 enter it as 3601.

The error you are getting mainly happens in case of Message server not being proper.

Hi Nutida,

Can you check, have you added "sapmsDEV" and the port 3600/tcp in your service file? if yes, then i think the entries that you have given under sld should be wrong. make sure that your group "PUBLIC" exists in R3 and the Host name is correct in sld.

Hi VIP,

I wonder this <b>Does the following error can affect to JCO connection fail?</b> I check my RFC connections through SLDCHECLK, It has an error as follow:

Exchange Infrastructure: Test LCR Connection

RFC host: %%RFCSERVER%%

program id: SAPSLDAPI_RD1

gateway host: webas

gateway service: sapgw00

Testing the RFC connection to the SLD java client...

RFC ping returned exception with message:

Please check your Getway Host & Getway Service using RZ70

Hi,

The problem could be in the MessageServer name that you have entered in the SLD (while adding the system info in SLD).

The SLD you are going to refer in the content admin for Jco connection. So it will display all the list of systems in the dropdown box while creating Jco destination.

One more problem could be with the ticket!!Change the user authentication from ticket to "user.password" while creating the Jco destination and enter your username and password on the R/3 system and try

Hi VIP,

The error occur when test its connection, which using Ticket method, and ping also fail.

<b>Would you please specific the part of SLD that i should correct? I am not sure where is used for configure the Message Server.</b>

Example: Part of SLD on XI

-SLD connection Parameters in the integration Server

-Server setting in SLD

-Configuring SLD Bridge

-Maintain a business system for the integration Server etc.

-

---

My scenario as follow:

-Backend, R/3 server

-Exchange Infrastructure, WEBAS server

-Adapter Engine, AII server

Hi Nutida ,

Are you getiing this error in contentAdministrator while configuring the Jco connection ?? (While testing the connection ?).

If so it looks like the system that you have added in the SLD is wrong. Please check the messageserver name once again in SLD and create connection once again.

Regards, VIP
