Hi,

Please help.

It's the storage that's important. You can run a database on an Exadata DB servers that doesn't access Exadata storage, in which case Smart Scans etc... will be disabled. So you may want to check your asm diskgroups. They have an attribute that tells whether they reside on Exadata storage or not. You can use something like this query to show you that information.
<pre>
column exadata_storage for a20
with b as (select group_number, value from v$asm_attribute where name = 'cell.smart_scan_capable')
select a.name diskgroup, state, b.value Exadata_storage
from v$asm_diskgroup a, b
where a.group_number = b.group_number(+)
and a.name like nvl('&diskgroup',a.name)
order by 1
SYS@SANDBOX> @exadata_diskgroups.sql
Enter value for diskgroup:
DISKGROUP STATE EXADATA_STORAGE
DATA CONNECTED TRUE
RECO CONNECTED TRUE
SCRATCH MOUNTED TRUE
SMITHERS DISMOUNTED
STAGE MOUNTED TRUE
SWING MOUNTED TRUE
SYSTEM MOUNTED TRUE
7 rows selected.
