Strangely the two guys from Flicker who preached on teamwork do not seem to be anyway comfortable with one another. Just watch the body language between the two, in particular at the opening when the guy on the right swung a very aggressive gesture to the left and how the guy on the left (british) ducked away. lol

It worked after the change u suggested.

Thanks,
Dev

$sth = $prodh->prepare( <<EOSQL );

have become:

$sth = $prodh->prepare( < <EOSQL );

there is an extra blank between < operators. try to remove it and let me know!

Unterminated operator at ./dg line 30.

sed -n ’s/.*\/\([[:digit:].]\+\)\/*.*/\1/p’

AFAIK, it’s not common to have cluster nodes across different LANs.
It’s more common to have different clusters in the same LAN!
Kind regards!

I’m facing issues with multicasting while setting-up cluster;
I have 2 node jboss cluster; each node is running separately in different LAN.
The apache/mod_jk configuration is fine but, both the Jboss nodes are not discovered in the cluster i.e., both displays the message saying “only one is present in the cluster”

I tried setting up the multicast Ip but, little conused!!!

Could you please share me the changes you made!!

Thanks,
Suresh
