size="+1">15.3 How do I匰tripe a tablespace across multiple devices?</font></b><p><B>Problem</B><p>Some heavily used tablespaces are causing contention on my database server抯 disk devices. It doesn抰 make sense to move the objects out of the tablespace and I want to stripe the tablespace across devices to reduce contention. Performance for simultaneous access of the tablespace will also be greatly improved if the tablespace spans multiple devices. How do I stripe a tablespace?<p><B>Technique</B><p>You can stripe a new tablespace at the database level when you initially create it by specifying multiple datafiles existing on more than one physical disk in the CREATE TABLESPACE statement. You can stripe an existing tablespace by using the ALTER TABLESPACE statement to create new, additional datafiles on other drives.<p><B>Steps</B><p><B>1.</B> Run SQL*Plus and connect as the WAITE user account. Use the START command to load and execute the CHP15_4.SQL script. The script and its output appears in Listing 15.2. The file contains a CREATE TABLESPACE statement distributing a single tablespace over multiple devices. The format of this statement assumes that you have three disk drives with drive designations C:, D:, and E:. If you do not have these drives, or if your operating system environment features different physical path specifications, then change the statement in script CHP15_4.SQL to reference valid disk drives and physical files on your system.<p>Listing 15.2 Running script CHP15_4.SQL in SQL*Plus to create a striped tablespace<p><code><b>SQL> START CHP15_4<p>1 CREATE TABLESPACE WAITE_TBS<p>2 DATAFILE 慍:\WAITE1.ORA⌨️ 快捷键说明
