DB2
product
installation
on
NFS
(Network
File
System):
The
installation
of
DB2
products
on
NFS
(Network
File
System)
is
not
recommended.
Running
DB2
products
on
NFS
(for
example,
NFS
mounting
/opt/IBM/db2/V9.1
and
then
running
off
code
that
was
physically
installed
on
a
remote
system)
requires
several
manual
setup
steps.
There
are
also
a
number
of
potential
issues
with
setting
up
NFS
for
DB2.
These
include
possible
problems
that
involve:
v
Performance
(impacted
by
network
performance)
v
Availability
(you
are
allowing
a
single
point
of
failure)
v
Licensing
(there
is
no
checking
done
across
machines)
v
Diagnosing
NFS
errors
can
be
difficult
As
mentioned,
the
setup
for
NFS
will
require
several
manual
actions
including:
v
Ensuring
that
the
mount
point
preserve
the
install
path
v
Permission
must
be
controlled
(for
example,
write
permission
should
not
be
given
to
the
mounting
machine)
v
DB2
registries
have
to
be
set
up
manually
and
maintained
across
all
mounting
machines
v
The
list
installed
DB2
products
and
features
command
(db2ls)
must
be
set
up
and
maintained
properly
if
you
need
to
detect
DB2
products
and
features
v
More
care
is
required
when
updating
your
DB2
product
environment
v
More
steps
are
required
when
cleaning
up
on
the
exporting
machine
and
the
mounting
machine
For
detailed
instructions,
