The control file in oracle is a small binary file necessary for the database to start and operate successfully. Each control file is associated with only one oracle database. Before a database is opened, the control file in oracle is read to determine if the database is in a valid state...

一、Oracle 控制文件 为二进制文件,初始化大小由CREATE DATABASE指定,可以使用RMAN备份 记录了当前数据库的结构信息,同时也包含数据文件及日志文件的信息以及相关的状态,归档信息等等 在参数文件中描述其位置,个数等等。通常采用分散放开,多路复用的原则。在mount阶段被读取,open阶段一直被使用 ...
对oracle controlfile进行转储 环境: rhel5.5,x64,oracle 10.2.0.5.12 转储命令: alter session set events 'immediate trace name controlf level 9'; 1. 该命令摘自: How to find the name of an old Restore Point when the database will not open: ORA-38760 (Doc ID 1288189.1) ...
2.controlfile文件的安全性 因为控制文件的重要性前文已经描述了,保证控制文件的安全重要性也就不言而喻了,oracle建议控制文件多路径保存(一个控制文件也是可以让系统运行的)。 有人可能会说存放在做了RAID冗余的(5或者10)上,当然,这样的做法,确实是能够防止磁盘故障导致控制文件丢失的问题,但故障未必都是磁盘故障...
说简单点,只要是备份的控制文件与当前的控制文件不一致进行恢复数据库,就需要使用到 unsing backup controlfile方式,而一旦使用了该方式,则需使用resetlgos选项来打开数据库。 有关控制文件的介绍请参考:Oracle 控制文件(CONTROLFILE) using backup controlfile 请参考:理解 using backup controlfile...
