IBM Frozen Dessert Maker VERSION 9 用户手册
By
default,
DB2
uses
rsh
when
executing
commands
on
remote
DB2
nodes,
for
example,
when
starting
a
remote
DB2
database
partition.
To
use
the
DB2
default,
the
rsh-server
package
must
be
installed
(see
table
below).
For
a
comparison
between
rsh
and
ssh,
see
the
“Security
issues
when
installing
DB2”
section
of
the
Administration
Guide:
Implementation.
If
you
choose
to
use
the
rsh
remote
shell
utility,
inetd
(or
xinetd)
must
be
installed
and
running
as
well.
If
you
choose
to
use
the
ssh
remote
shell
utility,
you
need
to
set
the
DB2RSHCMD
registry
variable
immediately
after
the
DB2
installation
is
complete.
If
this
registry
variable
is
not
set,
rsh
is
used.
For
more
information
on
the
DB2RSHCMD
registry
variable,
see
the
Performance
Guide
book.

The
nfs-utils
Network

All
required
packages
should
be
installed

configured
before
continuing
with
the
DB2
setup.
For
general
Linux
information,
see
your
Linux
