JCo Destinations

[Former Member]

Hi...

I'm creating a DC to access a RFC into a PI system... But when I try to configure the jCo destinations in web dynpro content administrator, I'm receiving the following message:

com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to SAP gateway failed Connect_PM  TYPE=B MSHOST=hodb008yar GROUP=Produção R3NAME=PYP MSSERV=sapmsPYP PCS=1 LOCATION    CPIC (TCP/IP) on local host with Unicode ERROR       partner '10.1.1.100:3309' not reached TIME        Thu Jul 09 09:19:42 2009 RELEASE     700 COMPONENT   NI (network interface) VERSION     38 RC          -10 MODULE      nixxi.cpp LINE        2770 DETAIL      NiPConnect2 SYSTEM CALL connect ERRNO       10060 ERRNO TEXT  WSAETIMEDOUT: Connection timed out COUNTER     1 

What can I do?!

Thanks in advance.

The SAP System is in Unix or Windows?

Also check if the port used by Jco is free or being utilised for some other programs

Hi,

Go trough the above link. You need to maintain the entries in the services files.

So... and how can I test?

Using telnet, the connection works...

So...

The bold number is not correct... Where can I define this number?!

perform :

In the file C:\windows\system32\drivers\etc\services add an entry

sapms<SID> <PORT>/tcp" (<SID> = R/3 system ID, <PORT> = message server port).

So... but my Ip address is not this...

Where can I change this? The IP address is wrong.

Thanks!

😃

[Former Member]

Add the IP in the host file and try again.

That's the problem... This IP ('10.101.3.20:3309' ) does not exists...

I need to know where can I define the correct Ip to this server... in SLD, not in windows system...

Thanks again.

check your public/private ip addresses and you may find the correct one.

[Former Member]

take the correct IP of the system and mention it in the JCO RFC provider in visual admin for the particular rfc which is connecting to the system, also add the host name and IP in the host file of the system.

I think that problem is on SLD...

All my ECC systems are working well, without any configuration in my Visual Admin. I need to change this wrong IP address into SLD and change them to the right......

What can I do?!

Thanks agian.

Please check the link below:

also i think you need to give the correct hostname or Ip in the rfc onnection too , if you give the hostname then the same details should also be mentioned in the host file of the system, so that it can get the IP of the system resolved.
