them
all
together
• Enkitec
has
developed
a
tool
called
Provisioning
Worksheet
that
is
mainly
used
for
sizing
and
consolidaKon
of
databases.
– AccounKng
Per

not
like
OEM12c
ConsolidaKon
Planner
which
is
just
host

uKlizaKon
– Consolidated

workload
analysis
across
mulKple
servers
– CPU,
memory
(SGA/PGA
&
HugePages),
storage
capacity
(storage
&
IOPS)
planning
– All
the
capacity

math
integrated
with
the
tool
(chip
efficiency
factor
across
mulKple
servers)
– Layout
instances
across
nodes
according
to
Preferred,
Available,
Failover
– Create
a
baseline
of
the
instances
node
layout
and
their
current
uKlizaKon
– Simulate
node
failure
and
different
what-‐if
scenarios
(add/delete
node,
increase/decrease
capacity,
etc.)
– VisualizaKon
module
to
quickly

– Cluster

– Recommended
