文档解释

ORA-00821: Specified value of sga_target stringM is too small, needs to be at least stringM

Cause: The specified value of sga_target is too small for the SGA to accommodate all of the necessary SGA components such as the log buffer, buffer pools, shared pool, etc.

Action: Set sga_target to the recommended value or reduce the values of any SGA component size parameters you have specified.

ORA-00821的意思是,SGA_TARGET值太小,需要至少stringM。

官方解释

ORA-00821表示您认为对于SGA_TARGET变量的值太小,因此必须至少达到stringM。SGA_TARGET变量需要足够大以容纳系统所有共享池子,但最小值应该至少为5MB。

常见案例

大多数ORA-00821异常是由于没有正确地设置SGA_TARGET变量而引起的。您可能会在“pfile”中使用“sga_target”变量,其值可能会在1MB时出现此错误。

正常处理方法及步骤

1. 确保您定义的SGA_TARGET值至少为5MB,并根据系统的要求或系统的内存容量调整此值。

2.使用下面的SQL语句来打开SGA_TARGET:

ALTER SYSTEM SET SGA_TARGET=valueM;

3. 重新启动数据库,以使变更生效。
