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=<fname> entries=<users> force=<y/n> ignorecase=<y/n> nosysdba=<y/n>

  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
