Hosts File The /etc/hosts file is seldom associated with problems. If you suspect Multi-Tier connection problems stem from /etc/hosts, take the following action:1. Open the server's /etc/hosts file.2. Locate the IP address which is associated with the server. For example:83.211.142.99 openlinux 3. Exit /etc/hosts.4. Obtain the output of ping on the server's hostname. For example:$ ping openlinux 64 bytes from 83.211.142.99: icmp_seq=1. time=0. ms 64 bytes from 83.211.142.99: icmp_seq=2. time=0. ms 5. Compare the IP address in /etc/hosts to the IP address returned by ping. If the addresses do not match, check the networking. If the addresses do match, take the following action: a) Use a text editor to open the oplrqb.ini file, which appears in the /bin sub-directory of the OpenLink server components installation. b) Locate the [Protocol TCP] section. c) Pass the IP address to the IPAddress parameter. Remove the semicolon (;). For example:IPAddress = 83.211.142.99 d) Save the changes and exit the file. e) Restart or reinitialize the Request Broker. f) Test.
