will
be
installed,
by
default,
in
the
x:\Program
Files\IBM\sqllib
directory,
where
x:
represent
the
drive
letter
of
the
drive
where
you
have
installed
your
DB2
product.
If
you
are
installing
on
a
system
where
this
directory
is
already
being
used,
the
DB2
product
installation
path
will
have
_xx
added
to
it,
where
_xx
are
digits,
starting
at
01
and
increasing
depending
on
how
many
DB2
copies
you
have
installed.

can
also
specify
your
own
DB2
product
installation
path.
For
information
on
errors
encountered
during
installation,
review
the
installation
log
file
located
in
the
My
Documents\DB2LOG\
directory.
The
log
file
uses
the
following
format:
DB2-ProductAbrrev-DateTime.log,
for
example,
DB2-ESE-Tue
Apr
04
17_04_45
2006.log

your
DB2
product
to
have
access
to
DB2
documentation
either
on
your
local
computer
or
on
another
computer
on
your
network,
then
you
must
install
the
DB2
Information
Center.
TheDB2
Information
Center
contains
documentation
for
the
DB2
database
system
and
DB2
related
products.
By

DB2
information
will
be
accessed
from
the
web
if

installed.
DB2
Express
memory
limits
and
the
DATABASE_MEMORY
configuration
parameter:
If
you
are
installing
DB2
Express
Edition
or
DB2
Express-C
Edition
on
a
system
that
has
more
memory
than
the
maximum
memory
limit
of
4GB,
as
outlined
in
the
terms
and
conditions
of
the
product,
you
need
to
explicitly
set
the
DATABASE_MEMORY
configuration
parameter
to
4GB
or
less,
so
that
the
Self
Tuning
Memory
Manager
will
work
within
your
licensed
memory
limits.
Note:
If
you
have
more
than
one
database
on
that
server,
the
sum
of
all
database
memory
usage
cannot
exceed
4GB.
You
can
use
the
Control
Center
or
the
UPDATE
DATABASE
CONFIGURATION
command
to
make
this
change.
For
example,
to
set
the
DATABASE_MEMORY
limit
to
4GB,
enter
the
following
command:
DB2
UPDATE
DATABASE
CONFIGURATION
using
DATABASE_MEMORY
1000000
IMMEDIATE;
CONNECT
RESET;
Also,
when
using
the
Configuration
Advisor
to
assist
you
in
configuring
the
performance
of
your
database,
you
need
to
set
the
Target
Memory
on
the
Server
page
to
a
percentage
of
your
total
system
memory
that
will
ensure
you
stay
under
the
4GB
memory
limit.
