Centralized
user-management
considerations
(Linux)
In
environments
that
include
security
software,
such
as
NIS
(Network
Information
Services)
or
NIS+,
there
are
some
installation
considerations.
The
DB2
installation
scripts
attempt
to
update
objects
that
are
under
the
control
of
the
security
packages,
such
as
users
and
groups,
and
will
not
be
able
to
do
so
if
NIS
or
NIS+
is
being
used
for
user
management.
At
instance
creation,
without
a
security
component
present,
instance
owner’s
group
list
is
modified
to
include
that
of
the
database
administrative
server
(DAS)
user’s
primary
group,
if
the
DAS
is
created.
If
the
instance
creation
program
is
unable
to
modify
these
properties
(it
will
not
if
NIS/NIS+
is
controlling
the
group),
it
reports
that
it
could
not.
The
warning
message
provides
the
necessary
information
to
manually
make
the
changes.
These
considerations
hold
true
for
any
environment
in
which
an
external
security
program
does
not
allow
the
DB2
installation
or
instance
creation
programs
to
modify
user
characteristics.
If
the
DB2
Setup
wizard
detects
NIS
on
your
computer,
you
are
not
given
the
option
of
creating
new
users
during
the
installation.
Instead,
you
must
choose
existing
users.
Consider
the
following
restrictions
if
you
are
using
NIS
or
NIS+:
v
Groups
and
users
must
be
created
on
the
NIS
server
before
running
the
DB2
Setup
wizard.
v
Secondary
groups
must
be
created
for
the
DB2
instance
owner
and
the
DB2
Administration
Server
on
the
NIS
server.
You
must
then
add
the
primary
group
of
the
instance
owner
to
the
secondary
DB2
Administration
Server
group.
Likewise,
you
must
add
the
primary
DB2
Administration
Server
group
to
the
secondary
group
for
the
instance
owner.
v
On
a
partitioned
DB2
database
system,
before
you
create
an
instance,
there
must
be
an
entry
for
the
instance
in
the
etc/services
file.
For
example,
if
you
want
to
create
an
instance
for
the
user
db2inst1
,
you
require
an
entry
similar
to
the
following:
DB2_db2inst1
50000/tcp
