Oracle重建控制文件的语法

Oracle在控制文件丢失的情况下，有时我们只能重建控制文件，具体语法例如：

 CREATE CONTROLFILE REUSE DATABASE "SQUAN" NORESETLOGS  ARCHIVELOG
    MAXLOGFILES 16
    MAXLOGMEMBERS 3
    MAXDATAFILES 100
    MAXINSTANCES 8
    MAXLOGHISTORY 292
LOGFILE
  GROUP 1 '/opt/oracle/oradata/squan/redo01.log'  SIZE 50M,
  GROUP 3 '/opt/oracle/oradata/squan/redo03.log'  SIZE 50M
-- STANDBY LOGFILE
DATAFILE
  '/opt/oracle/oradata/squan/system01.dbf',
  '/opt/oracle/oradata/squan/undotbs01.dbf',
  '/opt/oracle/oradata/squan/sysaux01.dbf',
  '/opt/oracle/oradata/squan/users01.dbf',
  '/opt/oracle/oradata/squan/test01.dbf',
  '/opt/oracle/oradata/squan/test02.dbf'
CHARACTER SET ZHS16GBK;


注意：上面语句datafile里没有temp表空间，数据库恢复完成之后需要重建临时表空间


alter tablespace temp add tempfile '/opt/oracle/oradata/squan/temp01.dbf' size 30m reuse;
create temporary tablespace temp tempfile '/opt/oracle/oradata/squan/temp01.dbf' size 30m
