so what is the big deal ?

trip down memory lane #1
28

who remembers these numbers ?

ORA-1631: max # extents 505 reached in table SCOTT.EMP
121 = 2k block size
249 = 4k block size

who thinks about extents anymore?
32

7.3 = unlimited extents

it is being performed by the software

automation ... towards autonomy

who remembers these parameters ?

ROLLBACK_SEGMENTS = (r0,r1,r2,r3,r4,r5,r6)
TRANSACTIONS_PER_ROLLBACK_SEGMENT = 20
CLEANUP_ROLLBACK_ENTRIES = 10

who thinks about undo anymore?
44

9.0 = automatic undo
45
undo_tablespace =

but it's more than automation

SQL> select count(*) from dba_rollback_segs;
COUNT(*)
----------
????

segment count growth / reduction ...

... decided by the database

autonomy =

"we do not know the implementation,
we do not set the rules,
decisions by the software"

we've been doing this for a while :-)

"Yeah...I know what that means"

You can scale to zero

140
load yesterday's data
cpu = 2

unleash the dogs :-)
cpu = 8

all other times = zero CPU cost
