Problem IT11530

Status: Closed |
LISTENER THREAD MAY NOT BE ABLE TO BIND TO PORT WHEN USING IPV6 ADDRESSES
|
| product: |
INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10 |
| Problem description: |
The listener thread may receive an OS error when trying to bind
the port with an IPv6 address. This results in an AF similar to:
Assert Warning: Unable to bind to the port (18105) on the host
() for the server (server1).

This may occur when using a specific IPv6 address other than the
loopback address ::1.
This problem may occur on releases of Linux where the option
"myhostname" is permitted for the hosts entry in
/etc/nsswitch.conf. The presence of this entry avoids the need
to enter the host's specific IP address into /etc/hosts and will
result in an IPv6 address being used by the listener thread if
IPv6 has been configured for at least one network interface. Red
Hat 7 is one such OS version where this option is available. |
| Problem Summary: |
****************************************************************
* USERS AFFECTED: *
* informix user with IPv6 enabled *

* PROBLEM DESCRIPTION: *
* See Error Description *
****************************************************************
* RECOMMENDATION: *
* Update to IBM Informix Server 12.10.xC6 *
**************************************************************** |
| Local Fix: |
The workaround is to allow the bind operation to use any of the
available IPv6 addresses on the server by prefixing the hostname
or address in column 3 of the sqlhosts file with an asterix "*".
Alternatively if IPv6 is not required it may be disabled by
setting the environment variable IFX_DISABLE_IPV6 or creating
the empty file $INFORMIXDIR/etc/IFX_DISABLE_IPV6. |
