创建oracle 数据字典基表的sql 文件是哪个文件

如题.

比如 dba_users基于数据字典user$基表上的视图，所以oracle在创建数据库时,是通过哪个sql创建这个文件的文件.

由一个参数决定：_init_sql_file'

select x.ksppinm name,y.ksppstvl value,x.ksppdesc describe

from sys.x$ksppi x,sys.x$ksppcv y

where x.indx=y.indx

and x.ksppinm='_init_sql_file';

NAME VALUE DESCRIBE

_init_sql_file ?/rdbms/admin/sql.bsq File containing SQL statements to execute upon database creation

察看 ?/rdbms/admin/sql.bsq ,

发现以下信息：

dcore.bsq

dsqlddl.bsq

dmanage.bsq

dplsql.bsq

dtxnspc.bsq

cluster c_user#(user#)

user$在表中，有一个字段lcount

lcount number default 0 not null, /* count of failed login attempts */

记录失败登录次数，如何查看用户登录失败次数，可以查看此字段

select name,lcount from user$ where name=具体用户名；

成功登录后，该值将为零.
