Database
A
collection
of
data
that
is
stored
in
tables.
In
OnDemand,
generally
speaking,
there
are
two
types
of
tables:
v
System
tables,
which
contain
information
about
the
objects
you
define
to
the
system,
such
as
users,
groups,
application
groups,
applications,
folders,
printers,
and
storage
sets.
There
are
also
system
tables
that
contain
information
OnDemand
uses
to
control
and
maintain
the
system.
v
Application
group
tables,
which
contain
the
index
data
for
the
reports
that
you
load
on
the
system
A
database
is
organized
into
parts
called
table
spaces.
Table
A
table
consists
of
data
logically
arranged
in
columns
and
rows.
For
example,
when
you
create
an
application
group,
the
system
creates
a
table
definition
that
contains
one
column
for
each
field
that
you
define.
When
you
load
a
report
into
an
application
group,
the
system
adds
one
row
to
an
application
group
table
for
each
document
contained
in
the
report.
Table
space
A
database
is
organized
into
table
spaces.
A
table
space
is
a
place
to
store
tables.
OnDemand
system
and
application
group
tables
exist
in
their
own
tables
paces
by
default.
The
OnDemand
system
table
spaces
are
listed
in
Appendix
C,
“System
control
tables,”
on
page
263.
The
names
of
the
application
group
table
spaces
are
created
by
OnDemand.
Index
In
OnDemand,
an
index
is
a
key
that
points
to
a
document.
An
index
allows
more
efficient
access
to
documents
by
creating
a
direct
path
to
a
document
through
pointers.
You
define
indexes
when
you
create
an
application
group.
The
indexes
should
contain
information
that
uniquely
identifies
a
document,
such
as
date,
account
number,
and
customer
name.
Indexes
are
populated
by
values
extracted
from
a
report
when
you
load
a
report
on
the
system.
Each
row
in
an
application
group
table
identifies
one
document.

However,
keep
in
mind
that
you
do
not
want
lots
of
indexes
on
a
report
just
to
have
indexes.
You
should
have
a
good
business
reason
to
have
an
index.
While
indexes
can
help
you
find
documents
faster,
having
too
many
of
them
can
slow
you
down
when
you
load
reports
on
the
system.
Every
time
you
add
a
new
row
(document)
to
a
table,
you
have
to
add
a
row
to
each
and
every
one
of
the
indexes
for
that
table.
So
the
more
indexes
that
you
have,
the
longer
it
may
take
when
you
load
a
report.
System
catalog
tables
Each
database
includes
a
set
of
system
catalog
tables,
which
describe
the
logical
and
physical
structure
of
the
data.
The
database
manager
creates
and
maintains
an
extensive
set
of
system
catalog
tables
for
each
database.
These
tables
contain
information
about
the
definitions
of
the
database
objects,
such
as
user
tables,
views,
and
indexes,
as
well
as
security
information
about
the
authority
that
users
have
for
these
objects.
They
are
created
when
the
database
is
created,
and
are
updated
in
the
course
of
normal
operation.
You
cannot
explicitly
create
or
drop
them,
but
you
can
query
and
view
their
contents
using
the
catalog
views.
Buffer
pool
A
buffer
pool
is
an
allocation
of
main
memory
allocated
to
cache
table
and
index
data
pages
as
they
are
being
read
from
disk
or
being
modified.
The
purpose
of
buffer
pools
is
to
improve
database
system
performance.
Data
can
be
accessed
much
faster
from
memory
than
from
a
disk;
therefore,
the
fewer
times
the
database
manager
needs
to
read
from
or
write
to
a
disk,
the
better
the
performance.
The
configuration
of
the
buffer
pool
is
the
single
most
important
tuning
area,
since
you
can
reduce
the
delay
caused
by
slow
physical
I/O.

Database
maintenance
You
need
to
maintain
the
OnDemand
database
to
keep
it
performing
in
an
optimal
manner.
IBM
recommends
that
you
run
the
following
database
maintenance
tasks
on
a
regular
basis:
v
Collect
statistics
on
tables
to
keep
optimization
information
up-to-date
v
Remove
index
data
that
has
reached
its
life
of
data
and
indexes
period
v
Migrate
indexes
to
archive
storage,
if
your
organization
needs
to
keep
indexes
for
some
period
of
time
after
users
no
longer
need
to
retrieve
the
documents
to
which
they
point
Collecting
statistics
Statistics
describe
the
physical
and
logical
characteristics
of
a
table
and
its
indexes.
You
should
collect
table
and
index
statistics
periodically
for
each
active
table.
These
statistics
are
used
by
the
database
manager
to
determine
the
optimal
way
to
access
the
data.
If
the
data
has
changed
significantly,
to
the
extent
that
the
information
last
collected
no
longer
reflects
the
actual
table
data,
then
performance
may
begin
to
deteriorate
when
users
are
accessing
data.
IBM
recommends
that
you
collect
statistics
at
least
once
a
week.
You
may
also
want
to
collect
statistics
after
loading
data
on
the
system.
For
example,
when
you
load
data
into
an
application
group
that
uses
Multiple
Loads
per
Database
Table,
OnDemand
may
add
rows
to
an
existing
table.
After
the
load
completes,
the
information
used
by
the
SQL
query
optimizer
does
not
reflect
the
latest
updates
to
the
table.
Before
you
allow
users
to
access
the
data,
you
should
collect
statistics
on
the
table.
How
to
collect
statistics
Utilities
provided
with
the
DB2
product
may
be
used
to
obtain
statistical
information
about
the
DB2
tables
defined
for
OnDemand.
See
appropriate
DB2
reference
material
for
information
about
using
DB2
utilities.
Removing
index
data
Indexes
expire
(are
eligible
for
removal)
because
their
life
of
data
period
has
passed.
The
indexes,
and
the
documents
that
they
point
to,
can
then
be
removed
from
the
system.
When
you
remove
an
index,
information
about
the
document
to
which
it
points
is
removed
from
the
database
(the
document
can
no
longer
be
retrieved).
However,
because
indexes
are
eligible
to
be
removed
does
not
mean
that
they
will
be
deleted
from
the
database.
OnDemand
does
not
delete
expired
index
data
from
the
database
until
expiration
processing
runs.
The
application
group
expiration
policy
determines
when
index
data
is
eligible
for
deletion
from
the
database.
You
define
the
expiration
policy
when
you
create
the
application
group.
The
following
properties
on
the
Storage
Management
page
comprise
the
expiration
policy:
v
Life
of
Data
and
Indexes.
The
length
of
time
in
days
to
maintain
index
data
and
documents
on
the
system.
After
the
index
data
has
been
on
the
system
for
this
number
of
days,
it
is
eligible
to
be
deleted.

Note:
If
you
specify
Never
Expire,
then
expiration
processing
is
disabled
for
the
application
group.
(That
is,
index
data
will
not
be
removed
from
the
database.)
v
Expiration
Type.
Determines
whether
individual
indexes
or
an
entire
table
of
index
data
is
deleted
at
a
time.
When
OnDemand
deletes
index
data,
it
deletes
a
row
(if
the
Expiration
Type
is
Document),
deletes
multiple
rows
(if
the
Expiration
Type
is
Load
or
Storage
Manager),
or
drops
a
table
(if
the
Expiration
Type
is
Segment).
The
amount
of
index
data
in
a
table
and
the
number
of
reports
the
data
represents
is
determined
by
the
Database
Organization.
If
the
Database
Organization
is
Multiple
Loads
per
Database
Table,
then
by
default,
a
table
of
index
data
can
hold
up
to
10
million
indexes.
These
types
of
tables
usually
hold
the
indexes
for
many
reports.
If
the
Database
Organization
is
Single
Load
per
Database
Table,
then
each
table
holds
the
indexes
for
one
and
only
one
report.
If
the
Expiration
Type
is
Storage
Manager,
the
index
data
will
not
be
deleted
until
the
Storage
Manager
(for
example,
OAM
OSMC)
has
deleted
the
object
and
the
ARSEXPIR
or
ARSEXOAM
program
is
run
to
delete
the
index
data.
Note:
If
the
Expiration
Type
for
any
application
group
is
Document,
Load,
or
Segment
and
you
run
the
ARSEXPIR
