The "Database Connection" dialog appears. Note: Although the name of the dialog would suggest that what you are creating at this point is a database connection, it is really a database connection pool. In later steps you will define database connections within the pool. 2. Select the appropriate value in the Database Driver drop-down menu-either DB2 (Type 2),or MQ SQL Server(Type 4)-depending on the database vendor. 3. If you chose MQ SQL Server(Type 4)in the Database Driver drop-down menu, then you must type the name of the computer on which the database server resides in the Host name field. 4. Type the name of the database in the Database field. 5. If you chose MQ SQL Server(Type 4)in the Database Driver drop-down menu, then you must type the port number through which clients communicate with the database server in the Port number field. 6. If you are connected to the InterChange Server Express instance that will use the pool, select that instance from the Connected Servers drop-down menu. 7. Type a name for the pool in the DBConnection Name field. You specify this database connection pool name when writing Java code to establish the connection in maps or collaboration templates. 8. Type the user name that should be used by InterChange Server Express to log in to the specified database in the Login field. 9. Type the password for the user name. 10. Type the maximum number of connections that should be established by the pool for all the individual database connection objects you plan to create within it in the Maximum connections field, or enable the Unlimited checkbox to allow as many connections to be established as are permitted by the database server configuration and licensing. Warning: Be careful when working in this field. It is not a single-line text field, even though it should be, so you can accidentally press Enter. You will not see the value you entered then, and will justifiably try to re-type the value. Then when you try to finish creating the database connection pool you receive an error that a valid value must be entered for the field. Do not press Enter in this field. Figure 34 on page 150 shows the "New Database Connection Pool" wizard. Chapter 8. Configuring database connection pools 149

The
“Database
Connection”
dialog
appears.
Note:
Although
the
name
of
the
dialog
would
suggest
that
what
you
are
creating
at
this
point
is
a
database
connection,
it
is
really
a
database
connection
pool.
In
later
steps
you
will
define
database
connections
within
the
pool.
2.
Select
the
appropriate
value
in
the
Database
Driver
drop-down
menu—either
DB2
(Type
2)
,or
MQ
SQL
Server(Type
4)
—depending
on
the
database
vendor.
3.
If
you
chose
MQ
SQL
Server(Type
4)
in
the
Database
Driver
drop-down
menu,
then
you
must
type
the
name
of
the
computer
on
which
the
database
server
resides
in
the
Host
name
field.
4.
Type
the
name
of
the
database
in
the
Database
field.
5.
If
you
chose
MQ
SQL
Server(Type
4)
in
the
Database
Driver
drop-down
menu,
then
you
must
type
the
port
number
through
which
clients
communicate
with
the
database
server
in
the
Port
number
field.
6.
If
you
are
connected
to
the
InterChange
Server
Express
instance
that
will
use
the
pool,
select
that
instance
from
the
Connected
Servers
drop-down
menu.
7.
Type
a
name
for
the
pool
in
the
DBConnection
Name
field.
You
specify
this
database
connection
pool
name
when
writing
Java
code
to
establish
the
connection
in
maps
or
collaboration
templates.
8.
Type
the
user
name
that
should
be
used
by
InterChange
Server
Express
to
log
in
to
the
specified
database
in
the
Login
field.
9.
Type
the
password
for
the
user
name.
10.
Type
the
maximum
number
of
connections
that
should
be
established
by
the
pool
for
all
the
individual
database
connection
objects
you
plan
to
create
within
it
in
the
Maximum
connections
field,
or
enable
the
Unlimited
checkbox
to
allow
as
many
connections
to
be
established
as
are
permitted
by
the
database
server
configuration
and
licensing.
Warning:
Be
careful
when
working
in
this
field.
It
is
not
a
single-line
text
field,
even
though
it
should
be,
so
you
can
accidentally
press
Enter
.
You
will
not
see
the
value
you
entered
then,
and
will
justifiably
try
to
re-type
the
value.
Then
when
you
try
to
finish
creating
the
database
connection
pool
you
receive
an
error
that
a
valid
value
must
be
entered
for
the
field.
Do
not
press
Enter
in
this
field.
