创建Oracle密码文件的命令 orapwd file=<> password=<> entries=最大数目 这里的file命名规则在unix/linux下orapw<Oracle_SID>,在windows下为 pwd<SID>.ora
Administrator's Reference 10g Release 2 (10.2) for UNIX-Based Operating Systems. 1. Log in as the Oracle software owner. (以Oracle管理员身份登入) 2. Use the orapwd utility to create the password file as follows(使用orapwd功能创建密码文件): $ $Oracle_HOME/bin/orapwd file=filename password=password entries=max_users filename The name of the file in which password information is written(filename指密码信息保存文件的文件名) The name of the file must be orapwsid, and you must supply the full path name. Its contents are encrypted. Typically,the password file is created in the $Oracle_HOME/dbs directory.(文件名必须为orapwsid,并需要提供完整路径,内容是加密的,通常情况下,密码文件被创建在$ORACLE_HOME/dbs路径下。) 请注意,unix环境中,password file一定是要用 orapw<SID>,没有例外。
Platform. Guide 10g Release 2 (10.2) for Microsoft Windows (32-Bit)
C:> orapwd FILE=pwdsid.ora PASSWORD=password ENTRIES=max_users where | FILE specifies the password filename. | SID identifies the database instance. | PASSWORD sets the password for account SYS. | ENTRIES sets maximum number of entries in password file. This corresponds to maximum number of distinct users allowed to connect to the database simultaneously with either the SYSDBA or the SYSOPER DBA privilege.
In search of the password file,Oracle Database looks in the registry for the value of parameter ORA_SID_PWFILE. If no value is specified, then it looks in the registry for the value of parameter ORA_PWFILE, which points to a file containing usernames, passwords, and privileges. If that is not set, then it uses the default: Oracle_BASEORACLE_HOMEDATABASEPWDsid.ORA. The default value is shared. 请注意,windows环境中,很大的部分是基于registry中变量ora_sid_pwfile 或者 ora_pwfile的设置, 缺省的值是 pwd<SID>.ora (unix中是没有这个.ora后缀的)。
1.这是因为Oracle采用了OS认证的方式,具体的可以查看 sqlnet.ora具体同容如下 SQLNET.AUTHENTICATION_SERVICES=(NTS) 将其改成SQLNET.AUTHENTICATION_SERVICES=(NONE) 这样就是Oracle认证方式了 2.因为用的OS认证方式,可以在操作系统->控制面版->计算机管理->用户将当前用户的属性组 ORA_DBA去掉,这时如果没有用户名及密码则不可以。 如下: SQL> connect /as sysdba ERROR:ORA-01031: insufficient privileges SQL> connect sys/Oracle as sysdba 已连接。
利用 orapwd重新创建一个就可以了。 本文出自:亿恩科技【www.enkj.com】 |
