Re: Server won't start

Hi,

what you describe, i.e. that the problem seems to be
"tied" to the server name -> I would think it still is a config
problem.
After all, if it would be a DNS problem, then other server
instances on the same box should have the same problem,
right ?

You may want to check that (due to sqlhosts entries) your
server on Node-B is not trying to listen at a socket that is
on Node-A ...
With the failover scenario I guess your server names are
the same on Node-A and Node-B ?
Make sure that the host column in sqlhosts file on Node-A
lists Node-A as hosts for the server name, but on Node-B
it needs to have Node-B as host in the host column of
sqlhosts file. (This can be easily overlooked when copying
the sqlhosts file from Node-A to Node-B ...).

Apart from that [ and there's also dependency on the version,
which you still heed as a secret as well as the platform ... :) ]
there's a restriction as to how long a servername can be.
So if you've two servernames in your sqlhosts that don't differ
within the significant length of the name, you could have an
effect that the name is truncated at a shorted length and
therefore the wrong line is picked from the sqlhosts file ...

That's what I can think of according to your descriptions.

Regards,
Martin

Hi,

Thanks for your email, we did the following but no postive results.

-> Bounce the unix box.
-> Checked the parameters, (parameters are fine because the same files are

used during the failover). Ports numbers are fine.
-> Did testing via shared memory and it works fine, when you try to use
"onsoctcp" connection it doesn't work.
-> Created another instance with different name, it works fine on the same

server.
-> When tried to use above settings for the orginal server, it didn't
work,
somehow the name of the instance is creating problem.

Additional info: Everything works fine on Node -A (2 instances) but when
we
failover(hacmp cluster) to Node-B, one instance doesn't work,
Informix-tech is pointing to DNS.

Sushil...
