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
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.
