Changing Members of a Tablespace Group
You can add a tablespace to an existing tablespace group by specifying the existing group name in the TABLESPACE GROUP clause of the CREATE TEMPORARY
TABLESPACE or ALTER TABLESPACE statement.
The following statement adds a tablespace to an existing group. It creates and adds tablespace lmtemp3 to group1, so that group1 contains
tablespaces lmtemp2and lmtemp3.
CREATE TEMPORARY TABLESPACE lmtemp3 TEMPFILE '/u02/oracle/data/lmtemp301.dbf'
SIZE 25M
TABLESPACE GROUP group1;
The following statement also adds a tablespace to an existing group, but in this case because tablespace lmtemp2 already belongs to group1,
it is in effect moved from group1 to group2:
ALTER TABLESPACE lmtemp2 TABLESPACE GROUP group2;
Now group2 contains both lmtemp and lmtemp2, while group1 consists
of only tmtemp3.
You can remove a tablespace from a group as shown in the following statement:
ALTER TABLESPACE lmtemp3 TABLESPACE GROUP '';
Tablespace lmtemp3 no longer belongs to any group. Further, since there are no longer any members of group1, this results in the implicit
deletion of group1.
Assigning a Tablespace Group as the Default Temporary Tablespace
Use the ALTER DATABASE...DEFAULT TEMPORARY TABLESPACE statement to assign a tablespace group as the default
temporary tablespace for the database. For example:
ALTER DATABASE sample DEFAULT TEMPORARY TABLESPACE group2;
首先添加两个临时表空间TMEP1和TEMP2到临时表空间组TEMP_GRP组
然后再让临时表空间组TEMP_GRP更改为默认的临时表空间
操作如下：

http://docs.oracle.com/cd/B19306_01/server.102/b14231/tspaces.htm#i1010733
Creating a Bigfile Tablespace
To create a bigfile tablespace, specify the BIGFILE keyword of the CREATE TABLESPACE statement
(CREATE BIGFILE TABLESPACE ...). Oracle Database automatically creates a locally managed tablespace with automatic segment space management. You can,
but need not, specify EXTENT MANAGEMENT LOCAL and SEGMENT SPACEMANAGEMENT AUTO in
this statement. However, the database returns an error if you specify EXTENT MANAGEMENT DICTIONARY or SEGMENT SPACE MANAGEMENT MANUAL.
The remaining syntax of the statement is the same as for the CREATE TABLESPACE statement, but you can only specify one datafile. For example:
CREATE BIGFILE TABLESPACE bigtbs
DATAFILE '/u02/oracle/data/bigtbs01.dbf' SIZE 50G
...
You can specify SIZE in kilobytes (K), megabytes (M), gigabytes (G), or terabytes (T).
If the default tablespace type was set to BIGFILE at database creation, you need not specify the keyword BIGFILE in the CREATE TABLESPACE statement.
A bigfile tablespace is created by default.
If the default tablespace type was set to BIGFILE at database creation, but you want to create a traditional (smallfile) tablespace, then specify a CREATESMALLFILE TABLESPACE statement
to override the default tablespace type for the tablespace that you are creating.
操作如下：
SQL>
create bigfile tablespace example datafile

5.4 Create a permanent tablespace to store data collected from various Oracle tools. Use the following specifications: 5.4.1 Tablespace name of TOOLS 5.4.2 File size of 10MB
操作如下：

5.5 Create a default permanent tablespace using the following specifications: 5.5.1 Tablespace name of USERS 5.5.2 File size of 48MB 5.5.3 Initial extent size of 4MB 5.5.4 Next extent size of 4MB

5.6 Create a permanent tablespace for storing segments associated with online transaction processing with high insert rates. Due to the potential high volume of concurrent inserts,
