1.備份controlfile

alter database backup controlfile to trace;

2.檢視dump引數

sys@ORCL> show parameter dump

NAME TYPE VALUE

------------------------------------ ----------- ------------------------------

background_core_dump string partial

background_dump_dest string d:\oracle\diag\rdbms\orcl\orcl\trace

core_dump_dest string d:\oracle\diag\rdbms\orcl\orcl\cdump

max_dump_file_size string unlimited

shadow_core_dump string none

user_dump_dest string d:\oracle\diag\rdbms\orcl\orcl\trace

3.檢視alter檔案在最後有剛才的操作

alter database backup controlfile to trace

Backup controlfile written to trace file d:\oracle\diag\rdbms\orcl\orcl\trace\orcl_ora_7176.trc

Completed: alter database backup controlfile to trace

4.檢視對應的trace file

Trace file d:\oracle\diag\rdbms\orcl\orcl\trace\orcl_ora_7176.trc
