【TechTarget中国原创】问：我怎样在Oracle中增加SGA_MAX_SIZE？在计算机启动的时候出现了以下错误："ORA-03113: end-of-file on communication channel"。请您告诉我增加SGA的一些步骤。我连接的是带有分区选项的Oracle9i Enterprise Edition Release 9.0.1.1.1。

答：在从spfile设置到pfile的过程中增加Oracle SGA_MAX_SIZE。然后在SQL*Plus中用 pfile启动数据库，如下：
Startup pfile=/u00/oracle/admin/ora/pfile/init.ora |
重新创建spfile。
Create spfile=/u00/oracle/admin/ora/pfile/spfile.ora
from pfile==/u00/oracle/admin/ora/pfile/init.ora |
