Ping failed in Ready callback for proc

The reason might be the any or all of the following : 

1) Windows hosts file - Improper IP Configuration
2) Orphan OPMN Services

Ping failed in Ready callback for proc might happen even during OBI 11g installation.
In such case check for both the issues

Solution:

1) Windows hosts file fix:
   Please make sure there is only one entry for each ip-address in the windows hosts file.
2) Orphan OPMN Services: 

   
   Follow the steps to rectify this issue: 

1. Stop all BI Services & also OPMN service
2. Under <MW_HOME>/instances/instance1/config/OPMN/Opmn/states.Check whether any file is present in this folder. This folder contains the running state of the OPMN & BI services. 
3. After closing all BI & OPMN services, if any file is present in the 'STATES' folder. Remove them. And double check whether the OPMN service is closed. 
4. Re-Start the OPMN Services. 

This should fix the issue.
