Uninstalling
your
DB2
product
Uninstalling
your
DB2
product
(Windows)
This
task
provides
steps
for
completely
removing
your
DB2
product
from
your
Windows
operating
system.
You
should
only
perform
this
task
if
you
no
longer
require
existing
your
DB2
instances
and
databases.
If
you
are
uninstalling
the
DB2
default
copy,
and
you
have
other
DB2
copies
on
your
system,
you
should
use
the
db2swtch
command
to
choose
a
new
default
copy
before
you
proceed
with
the
uninstallation.
Also,
if
your
database
administration
server
(DAS)
is
running
under
the
copy
being
removed,
you
should
move
your
DAS
to
a
copy
that
is
not
being
removed.
Otherwise,
you
will
have
to
recreate
the
DAS
using
db2admin
create
command
after
the
uninstall
and
you
might
have
to
reconfigure
the
DAS
for
some
functionality
to
work.
Procedure:
To
remove
your
DB2
product
from
Windows:
1.
Drop
all
databases.
You
can
drop
databases
using
the
Control
Center
or
drop
database
command.
If
you
drop
your
databases,
all
of
your
data
will
be
gone.
2.
Stop
all
DB2
processes
and
services.
This
can
be
done
through
the
Windows
Services
panel
or
by
issuing
the
db2stop
command.
If
DB2
services
and
processes
are
not
stopped
before
attempting
to
remove
your
DB2
product,
you
will
receive
a
warning
containing
a
list
of
processes
and
services
that
are
holding
DB2
DLLs
in
memory.
3.
You
have
two
options
for
removing
your
DB2
product:
Add/Remove
Programs
Accessible
through
the
Windows
Control
Panel,
use
the
Add/Remove
Programs
window
to
remove
your
DB2
product.
Refer
to
your
operating
system’s
help
for
more
information
about
removing
software
products
from
your
Windows
operating
system.
db2unins
command
You
can
run
the
db2unins
command
to
remove
your
DB2
product.
Using
this
command,
you
can
uninstall
multiple
DB2
products
at
the
same
time
using
the
/p
parameter.
You
can
also
silently
uninstall
DB2
products
by
using
/u
parameter
which
will
remove
the
DB2
products
specified
in
the
response
file.
For
more
information,
see
the
db2unins
command
topic.
Unfortunately,
your
DB2
product
cannot
always
be
removed
by
using
the
Control
Panel
-
Add/Remove
Programs
facility
or
using
the
db2unins
/p
command
or
the
db2unins
/u
command.
The
following
uninstallation
option
should
ONLY
be
attempted
if
the
above
method
fails.
To
forcefully
remove
all
DB2
copies
from
your
Windows
system,
run
the
db2unins
/f
command.
This
command
will
perform
a
brute
force
uninstallation
of
ALL
DB2
copies
on
the
system.
Everything
except
user
data,
such
as
DB2
databases,
will
be
forcefully
deleted.
