思路/方法 Measuring restore speed 提出了speed-factor,用以衡量存储速度. Container capping 限制恢复文件时使用的container个数,为了保证调用container数目小于上限,有时需要放弃一部分重删效果(将某chunk在新的container中复制一次) capping操作需要将数据形成segment(20M左右,5000个4KB chunk) segment处理 读取一个segment大小的chunk到buffer中,确定每个chun…

spfile一般在$ORACLE_HOME/dbs(linux)目录,如果你丢失了spfile并不会引起实例立刻停掉,你的实例可以继续操作,尽管当你restore spfile的时候需要关闭重启实例,那么可以通过多种方式进行恢复 1).通过alert_sid.log,alert里面包含你修改过的所有参数,可以根据alert日志重新创建pfile,再创建spfile恢复 2).如果pfile还存在 shutdown immediate; create spfile from pfile; 创建sp…
