Re: -956 error message while HADR IDS 10 UC4

In Response To: -956 error message while HADR IDS 10 UC4 (DEEPAK BISWAS)

Hi,

critical is, that the user informix is trusted.
Have you tried as user informix to do the remote
connect on OS level (rlogin or similar)?

I never heard that you can enter IP-address only in
sqlhosts file, but not the hostname. This I think is not
a (version specific) problem of IDS.

It is more likely a setup problem between the machines.
First make sure that each machine "knows" itself by
name. Usually this is done by an entry in /etc/hosts.
There may be a difference between long and short
name (with and without full domain name qualification).
So you may have to put both into /etc/hosts.

Next see whether the peer is known by name
on each machine. E.g. use "nslookup" utility or
something similar. You may have to adjust some
setup regarding DNS utilization vs. files (like /etc/hosts).

As a last test, you can use dbaccess on one machine
to connect to server on the other and vice versa. Do
this as user informix and it should work without requiring
the password.

Once all this is correctly in place, HDR should work.

BTW: you can use $INFORMIXDIR/etc/hosts.equiv
instead of /etc/hosts.equiv. The syntax in the file is
the same, only $INFORMIXDIR/etc/hosts.equiv will
be effective for IDS only (but not all the other UNIX
functionality).

Regards,
Martin
