【Oracle】ORA-32017和ORA-00384错误处理
问题描述
执行如下命令，修改db_cache_size的大小时候发生了ORA-32017和ORA-00384错误。
ALTER SYSTEM SET db_cache_size=100M scope=spfile
错误内容信息：
ORA-32017: failure in updating SPFILE
ORA-00384: Insufficient memory to grow cache
问题原因和解决
自动内存管理有效的时候（AMM）时候，如果设置了比当前缓存大小较大的值，会发生ORA-384。
作为解决方法，可以通过V$MEMORY_DYNAMIC_COMPONENTS视图确认当前“缓冲区大小”，
然后设定db_cache_size小于该大小的大小。
例：
select COMPONENT,CURRENT_SIZE from
V$MEMORY_DYNAMIC_COMPONENTS where COMPONENT='DEFAULT buffer cache'
