Problem IC71765
|
Status: Closed |
DB2ICRT HANGS WHEN HOSTNAME MAPS TO AN INCORRECT IP ADDRESS |
| product: |
DB2 FOR LUW / DB2FORLUW / 950 - DB2 |
| Problem description: |
If the hostname resolves to an invalid IP address in /etc/hosts,
db2icrt hangs because it tries to bind on each port.
e.g. Compare the IP address specified in /etc/hosts with the
adapter
# hostname
machineA
# cat /etc/hosts | grep machineA
1.2.3.4 machineA.yourdomain.com
# ifconfig eth1
eth1 Link encap:Ethernet HWaddr 00:E0:81:5A:3F:AF
inet addr:9.26.118.54 Bcast:9.26.119.255
Mask:255.255.254.0
...
After applying the fix, you will see the following error message
when the ip address associated with the hostname is invalid:
DBI1922N The host name is not valid.
Explanation:
The TCP/IP host name parameter is not valid or does not exist.
User response:
Ensure that TCP/IP is operational on the system. If a domain
name server
is used, ensure that the domain name server machine is active.
Issue the
command again using the correct TCP/IP host name. |
