Siva,

Were you able to fix this?

If yes, what did you do.

If not, I remember seeing this when I was doing the post-installation config after the installation of XI server. I have seen this on the XI ABAP engine.

On the visual admin, for the JCO service, there are a couple of JCO destinations defined. For each of the JCO connection, there is a field which indicates the number of connections to be open.

Make sure that the total number of connections are less than 100.

Now try the connection test

Please let us know what you got.

hi

try this

Look at SAP note 314530,316877

you have to set a enviroment variable:

set CPIC_MAX_CONV = 500 (WINDOWS)

setenv CPIC_MAX_CONV 500 (unix)

hope its helps

Hi, I got confused with your answer, some body in the forum saying at PI side.

thanks

[rodrigoalejandro_pertierr]

the enviroment variables must set in PI side, but test of RFC in R3 side in your case

Hi Experts,

In this RFC->File scenario, To test the connection we can test the RFCdestination type TCP/IP in R3 by using test connection in sm59, how can i test whether it is properly connected from from XI to R3.

Please help me out,

Thanks

Hi Siva,

>how can i test whether it is properly connected from from XI to R3.

Go to Sm59 in XI select the RFC connection, Double click on it..and you will find Test connection Button.

hi check the below links

1)Adaptive RFC troubleshooting guide

https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/f3f93ee7-0c01-0010-2593-d7c...

and

https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/d0019b1a-775f-2910-beb8-d81f27d0...

If you are having problems connecting to the SAP instance, open a DOS-window and type:

telnet 131.200.65.109 3302

And press ENTER. If the whole screen goes black and all letters on it disappear, you are reaching the server. If you get a "Connecting To 131.200.65.109..." message that just sits there, you aren't reaching the server.

note:reward points if solution found helpfull.....

Hi,

Should i Set the environmental varible at R3 side or XI side?

thanks

Worth noting that this environment variable at the OS level is also associated with the SAP profile parameter gw/max_conn_per_wp. See SAP note 972262 for example of reference in post installation steps for a SAP system.

That is environment variable CPIC_MAX_CONV

HI

Make sure you have a logon group called PUBLIC in the backend system which points to a real system. The RFC call is trying to access the localhost (127.0.0.1), which often means a badly defined logon group, or your services and/or hosts file on the portal server have been mucked uo.

refer

The RFC's/JCO's use resources which can configured on the RFC application server. please refer http://help.sap.com/saphelp_nw04s/helpdata/en/b2/ae1c3d2b058c4ce10000000a114084/content.htm
