AutoConfig could not successfully execute the following scripts: afdbprf.sh

While doing Oracle application cloning, I got the following error while running autconfig ..... Make sure db listener is up and running while running autoconfig 

Error:

AutoConfig could not successfully execute the following scripts: afdbprf.sh

  AutoConfig could not successfully execute the following scripts:

    Directory: /mnt/DEVapps/oracle/trcdevdb/11.2.0/dbhome_1/appsutil/install/TRCDEV_gddevdb1

      afdbprf.sh              INSTE8_PRF       

In log file I see this error:-

Enter value for 1: Enter value for 2: Enter value for 3: ERROR:

ORA-12541: TNS:no listener

But listener is up and running,

gddevdb1.tireco.com:/mnt/DEVapps/oracle/trcdevdb/11.2.0/dbhome_1/appsutil/scripts/TRCDEV_gddevdb1>ps -ef | grep tns

Work Around / Fix -

When I did nslookup gddevdb1(hostname)  and it returned a different ip address then what was defined in /etc/hosts file ... which was causing it to fail to connect to listener

After running autoconfig again, it completed successfully.

Updating rdbms version in Context file to db112

Updating rdbms type in Context file to 64 bits

Configuring templates from ORACLE_HOME ...

vi /mnt/DEVapps/oracle/trcdevdb/11.2.0/dbhome_1/appsutil/log/TRCDEV_gddevdb1/08222201/adconfig.log

AutoConfig completed successfully.
