is
used
in
this
manual
to
mean

Productivity
Facility
(ISPF),
the
Interactive
System
Productivity
Facility/Program
Development
Facility
(ISPF/PDF),
and
the
Time-Sharing
Option
(TSO).
A
good
working
knowledge
of
Virtual
Storage
Access
Method
(VSAM)
is
desirable
but
not
essential.
To
implement
security,
you
must
know
the
Resource
Access
Control
Facility
(RACF)
or
a
similar
product.
To
implement
IBM
Tivoli
Workload
Scheduler
for
z/OS
exits
or
subroutines,
you
must
know
job
control
language
(JCL)
and
have
a
good
working
knowledge
of
a
programming
language,
for
example,
assembler
or
PL/I.
You
can
use
programming
languages
that
support
OS/390
linkage
conventions
and
that
can
load
and
delete
an
assembler
program.

Using
LookAt
to
Look
Up
Message
Explanations
LookAt
is
an
online
facility
that
lets
you
look
up
explanations
for
most
messages
you
encounter,
as
well
as
for
some
system
abends
and
codes.
Using
LookAt
to
find
information
is
faster
than
a
conventional
search
because
in
most
cases
LookAt
goes
directly
to
the
message
explanation.
You
can
access
LookAt
from
the
Internet
at:
http://www.ibm.com/eserver/zseries/zos/bkserv/lookat/
or
from
anywhere
in
z/OS
or
z/OS.e
where
you
can
access
a
TSO/E
command
line
(for
example,
TSO/E
prompt,
ISPF,
z/OS
UNIX
System
Services
running
OMVS).
The
LookAt
Web
site
also
features
a
mobile
edition
of
LookAt
for
devices
such
as
Pocket
PCs,
Palm
OS,
or
Linux-based
handhelds.
So,
if
you
have
a
handheld
device
with
wireless
access
and
an
Internet
browser,
you
can
now
access
LookAt
message
information
from
almost
anywhere.
To
use
LookAt
as
a
TSO/E
command,
you
must
have
LookAt
installed
on
your
host
system.
You
can
obtain
the
LookAt
code
for
TSO/E
from
a
disk
on
your
(SK3T-4270)
or
from
the
LookAt
Web
sites

adds
the
JESLOG=NOSPIN
parameter
to

when
the
following
conditions
both
occur:
You

(JSC).
v
To
increase
the
virtual
storage
from
16MB
to
2GB,
the
Tivoli
Workload
Scheduler
for
z/OS
components
have
been
changed
to
use
31-bit
addressing
mode
instead
of
24-bit.
End-to-End
Functions
v
For
fault-tolerant
workstations,
you
can
continue
to
use
centralized
scripts,
which
are
stored
in
the
JOBLIB
dataset.
With
centralized
scripts,
you
can
perform
variable
substitution,
automatic
recovery,
JCL
editing,
and
job
setup
(as
for
the
jobs
in
the
JOBLIB).
However,
this
implies
a
loss
of
fault
tolerance
and
requires
downloading
the
script
to
the
agent
every
time
the
job
is
submitted.
You
need
to
weigh
the
benefits
and
disadvantages
of
using
centralized
scripts.
v
You
can
use
a
new
syntax
to
recover
non-centralized
jobs
on
distributed
agents
automatically
when
the
jobs
abend.
This
recovery
is
similar
to
the
recovery
in
the
distributed
environment.
v
You
can
use
variable
substitution
for
jobs
that
run
on
fault-tolerant
workstations
and
that
do
not
use
centralized
scripts.
Tivoli
Workload
Scheduler
for
z/OS
supplied-variable
and
user-
defined
variable
tables
are
supported.
v
You
can
enable
firewall
support
and
SSL
authentication
in
end-to-end
scheduling.
v
You
can
specify
a
success
condition
for
each
job
that
determines
whether
a
job
is
considered
successful
or
abended.
v
You
can
specify
or
modify
the
deadline
time
for
a
job
or
a
job
stream.
v
There
are
new
log
files
for
Netman,
Batchman,
Mailman,
Writer,
and
Translator.
v
Multiple
domain
managers
can
be
connected
to
the
controller.
This
allows
greater
flexibility,
scalability,
and
improved
performance.
v
You
can
make
an
application
or
an
operation
dependent
on
the
existence
of
one
or
more
files
before
it
can
begin
execution.
v
You
can
activate
and
deactivate
the
submission
of
jobs
scheduled
in
an
end-to-end
environment.
v
You
can
enable
or
disable
the
auditing
trail
of
a
plan.
v
You
can
change
the
status
of
distributed
agents
and
switch
their
domain
manager.
v
You
can
refresh
the
content
of
the
work
directory.
v
You
can
use
the
ISPF
panels
to
produce
an
APAR
tape
that
collects
end-to-end
data.
v
You
can
use
the
Job
Migration
Tool
to
migrate
from
tracker
agents
to
distributed
agents.
Server
Connectivity
and
Sysplex
v
The
server
can
use
APPC
and
TCP/IP
in
simultaneous
connections
with
the
Job
Scheduling
Console,
PIF,
ISPF
panels,
and
distributed
agents.

v
When
an
application
is
moved
to
another
system
in
a
sysplex
environment,
for
example,
for
maintenance
of
the
current
system
or
for
a
failure,
the
application
can
be
reached
under
the
same
virtual
IP
address.
Using
a
dynamic
virtual
IP
address
makes
the
end-to-end
configuration
more
flexible,
because
your
application
is
independent
of
the
TCP/IP
stack
within
the
sysplex.
How
to
Read
Syntax
Diagrams
Throughout
this
manual,
syntax
is
described
in
diagrams
like
the
one
shown
here,
which
describes
the
SRSTAT
TSO
command:
SRSTAT

The
symbols
have
these
meanings:
The
statement
begins
here.
The
statement
is
continued
on
the
next
line.
The
statement
is
continued
from
a
previous
line.
The
statement
ends
here.
Read
the
syntax
diagrams
from
left
to
right
and
from
top
to
bottom,
following
the
path
of
the
line.
These
are
the
conventions
used
in
the
diagrams:

the

An
arrow
returning
to
the

above
the

indicates
an

you
can

If
a

is
required
between
items,
it
is
shown
on
the
repeat
arrow.

v
If
you
can
choose
from
two
or
more
items,
they
appear
vertically
in
a
stack.
If
you
must
choose
one
of
the
items,
one
item
of
the
stack
appears
on
the
main
path:

If
choosing

the

below
the
main

A

the

are
default

Keywords
appear
in
uppercase
(for
example,
STATEMENT).
v
Parentheses
and
commas
must
be
entered
as
part
of
the
command
syntax,
as
shown.
v
For
complex
commands,
the
item
attributes
might
not
fit
on
one
horizontal
line.
If
that
line
cannot
be
split,
the
attributes
appear
at
the
bottom
of
the
