Cause :

Issue with hosts file


Solution :

##In hosts file the localhosts doesn't have alias name dbccop1.So,If we connect to database without mentioning TDPID.Then By default it tries to connect to dbccop1.As it doesn't have entries in hosts file.It's getting from DNS.But,the Entries in DNS returning different Ip address where database not running on those systems and resulting in failure.

/etc/hosts file
Before change:
127.0.0.1 localhost barcop1
After change:
127.0.0.1 localhost dbccop1
