oracle密码文件的重建

oracle11g的密码文件是在目录 /u01/app/oracle/product/11.2.0/dbhome_1/dbs下面

新建密码文件的命令

orapwd file=orapwcapaas（orapw+数据库SID） password=Oracle123（SYS用户的密码） entries=10 （最大尝试次数）

orapwd file=orapwwubin01 password=oracle123 entries=10 (这个是对的)

orapwd file =orapwwubin01 password=oracle123 entries=10 （这个会报错，因为file =orapwdsid=号之前有空格）

报错详细信息：

Usage: orapwd file= entries= force= ignorecase= nosysdba=

where

file - name of password file (required),

password - password for SYS will be prompted if not specified at command line,

entries - maximum number of distinct DBA (optional),

force - whether to overwrite existing file (optional),

ignorecase - passwords are case-insensitive (optional),

nosysdba - whether to shut out the SYSDBA logon (optional Database Vault only).

There must be no spaces around the equal-to (=) character.

在遇到报错 ORA-01031 insufficient privileges的时候可以尝试重建密码文件
