ORA-00823 错误表示“指定的 SGA_TARGET 值大于 SGA_MAX_SIZE”。这是一个 Oracle 数据库错误,通常发生在数据库启动时或尝试动态调整系统全局区(SGA)大小时。 2. SGA_TARGET 和 SGA_MAX_SIZE 参数的作用和关系 SGA_TARGET:指定 SGA(系统全局区)的目标大小。Oracle 会尝试将 SGA 调整为这个大小,以满足数据库...
ORA-00823: Specified value of sga_target greater than sga_max_size 这说明:设置的sga_target值大于了sga_max_size. 解决步骤: 1. 更改spfileSID.ora文件中的sga_target 为0; 2. 另启动一个会话并重启数据库,问题解决. 建议: a.在设置sga_target是要先查看一下sga_max_size的大...
The value of sga_max_size has been changed without specifying "M" meaning "Megabyte", which is definitely smaller than the current sga_target. And ORA-823 occurs when trying to correct it.1. Setting sga_max_size without specifying "M"...

ORA-00823: Specified value of sga_target greater than sga_max_size 可是客户的数据库为什么SGA_TARGET的值会大于SGA_MAX_SIZE呢?这应该是和ORACLE的granule(粒度)有关系,granule是ORACLE内存中的一片连续区域,是连续虚拟内存分配的单位,粒度是9i新引入的参数,其大小取决于SGA_MAX_SIZE参数所定义的SGA总的大小,...

ORA-00823: Specified value of sga_target greater than sga_max_size 从上面这个例子的错误报告中,我们还可以发现一点那就是SGA_TARGET是可以在本实例内动态修改的,请看: SQL> alter system set sga_target=500m; System altered. 问题又出现了,既然SGA_TARGET除了带来这个ASMM新特性以及可动态修改以外,它的含...
