JCo call issue in MII 15.0

Hi Experts,

we have recently instllaed MII 15.0 SP4 patch 6 on Linux. since this is new installation I want to validate the system

so please tell me what are all parameters I need check.

please provide link for installation document for MII 15.0 if any.

I am trying to integrate MII with SAP.

I am facing issue with JCo interface action as below. since this is first time we are using JCo actions. do we need to create any data server? or do we need to create any JCo RFC provider in NW for gateway service? did not find any clues in NW logs. Please advice.

Thanks in advance,

Eswar
