  环境:oracle10g,操作系统5.2

  php?/%CA%FD%BE%DD%BF%E2%CF%B5%CD%B3' target='_blank'>数据库系统在rootvg下/oracle文件系统下,

  数据文件在datavg下/oradata文件系统下

  控制文件在 $/ORACLE_HOME/dbs/一个和/oradata下两个

  重做日志文件在 $/ORACLE_HOME/dbs/和/oradata下每组日志文件各一个,共三组

  有最新spfile文件备份。

  1、rootvg损坏,重新安装操作系统。

  2、安装oracle数据库系统文件

  3、恢复spfile文件到$/ORACLE_HOME/dbs/下,

  4、startup nomount,出现错误提示,建立$/ORACLE_BASE/hb052500/cdump 和udump

  5、startup nomount,出现错误提示

  SQL> startup nomount

  ORA-00444: background process "MMAN" failed while starting

  ORA-07446: sdnfy: bad value '' for parameter .

  ORA-07446 sdnfy: bad value 'string' for parameter string.

  Cause: The directory specified as the value for the stated parameter could not

  be used.

  Action: Make sure the directory you have specified is a valid directory/file

  specification.

  6、建立pfile文件

  SQL> create pfile from spfile;

  File created.

  7、查看pfile文件,按照pfile文件中列出的路径,建立相应路径后台进程目录和归档目录

  *.log_archive_dest_1='LOCATION=/oracle/app/oracle/OraHome/dbs/archive'

  *.background_dump_dest='/oracle/app/oracle/admin/hb052500/bdump'

  $ cd $/ORACLE_BASE/hb052500/

  $ ls

  cdump udump

  $ mkdir bdump

  $ cd $ORACLE_HOME/dbs/

  $ ls

  hb052500 init.ora inithb052500.ora

  hc_hb052500.dat initdw.ora spfilehb052500.ora

  $ mkdir archive

  8、startup nomount成功。

  $ sqlplus /nolog
