We've recently changed our Oracle cluster. When we tried to change the ODBC
URL connection string in CF we get the following error:

Connection verification failed for data source: DB1
[]java.sql.SQLException: Io exception: Connection
refused(DESCRIPTION=(ERR=1153)(VSNNUM=153093376)(E RROR_STACK=(ERROR=(CODE=1153)(
EMFI=4)(ARGS='(ADDRESS=(PROTOCOL=TCP)(HOST=<server _name>)(PORT=1521))'))(ERROR=(
CODE=305)(EMFI=1))))
The root cause was that: java.sql.SQLException: Io exception: Connection
refused(DESCRIPTION=(ERR=1153)(VSNNUM=153093376)(E RROR_STACK=(ERROR=(CODE=1153)(
EMFI=4)(ARGS='(ADDRESS=(PROTOCOL=TCP)(HOST=<server _name>)(PORT=1521))'))(ERROR=(
CODE=305)(EMFI=1))))

What's interesting is that the port has been changed to 1625, so I have no
idea where it's getting 1521 as the Port. I checked for trailing spaces and
made sure the service name didn't contain any periods. The tnsnames.ora file
has the correct entries. Any help is appreciated.
