If you want to know what object are read
|
||
|
|
in ASH then use the following script
|
||
|
|
Particularly :
|
||
|
|
-- if current_obj = 0 then this means you are reading from
|
||
|
|
undo block(useful to check read consistency)
|
||
|
|
|
||
|
|
-- if current_obj = -1 then this means you are working on cpu
|
||
|
|

|

|
|
select
|
||
|
|
decode(current_obj#
|
||
|
|
,0
|
||
|
|
,'undo block'
|
||
|
|
,-1
|
||
|
|
,'cpu'
|

|
|
,current_obj#) cur_obj
|
||
|

|
