What's the maxim number of datafiles a tablespace can contain?
|
1022
|
|
|
|
What kind of parameter specifies how a tablespace is used?
|
storage parameter
|
|
|
|
this parameter defines the characteristics of the tablespace and how the tablespace grows
|
storage
|
|
|
|
Can more than one datafile make up a tablespace?
|
yes
|
|
|
|
Which method of taking a tablespace offline is this? All available datafiles are checkpointed; can occur even if a datafile is unavailable
|
temporary
|
|
|
|
Which method of taking a tablespace offline is this? Checkpoints all datafiles; all datafiles must be available and functioning properly
|
normal
|
|
|
|
which form of taking a tablespace offline is this? Datafiles are not checkpointed
|
immediate
|
|
|
|
this process automatically coalesces tablespaces (defragmenting extents), unless the process has been disabled
|
smon
|
|
|
|

|
parallel
|
|
|
|
Enter the command to efficiently create datafiles in parallel

|
|
|
|

This tablespace clause is very important because it is used to specify the initial size and characteristics of the tablespace as well as the future growth of that tablespace.
|
storage
|
|
|
|
Within the tablespace storage clause, this specifies the size of extents after the second extent (that is, from the third extent on).
|
pctextent
|
|
|
|
within the tablespace storage clause, what is the default value for the pctincrease? what is the default value for pctincrease relating to rollback segments?
|
50, 0
|
|
|
|
linked list of available data blocks in the extent that have free space greater than PCTFREE. These are essentially lists of blocks that are available for inserts.
|
freelists
|
By having more than one of these, you can reduce contention on inserts.
|
|
|

|
null
|
|
|
|

|
storage initial 150k
|
|
|
|
The DEFAULT STORAGE clause is used for the creation of?
|
extents
|
|
|
|
Complete the STORAGE command to specify an initial extent size of 5M, the next extent size of 2M, and the size of all subsequent extents also to be 2M.
|
default storage
initial 5M NEXT 2M PCTIncrease 0 |

|
alter tablespace dogs readonly;
|
|
|

is the resource from which the schema objects obtain their space.
|
tablespace
