Wild-assed guesses here:
(1) Check whether the fully qualified system name is in the hosts table
(2) Check whether the rdb name matches the configured host name

We just recently got a new lead on our Tomcat/BIRT performance issue. It
seems that it's taking longer for code on the customer box to establish a
JDBC connection to the Host Server ports through the Loopback ports than it
takes us to establish that same connection from the other side of the
continent (and an unknown number of relays) away.

We know we can open a connection through these ports -- including through
JDBC -- in less than 1 second over the Internet from our IP address. But
somehow, making a connection from Java running on the same physical box
takes 5 or more seconds.

Any suggestions on an easy way to establish a test connection to the Host
Servers ports from ILE RPG or ILE C, without calling out to JAVA to use
JDBC?
