在$ORACLE_HOME/rdbms/admin下基本都是.sql文件，.bsq文件并不多，但.bsq文件非常重要
bsq文件在创建数据库的时候被调用，执行了许多创建数据库基表和索引等的一些sql语句，bsq应该可以理解为basic sql。
sql.bsq 片段：
dbxxx:/oracle/app/db_1/rdbms/admin> more sql.bsq
rem
rem $Header: rdbms/admin/sql.bsq /main/606 2008/07/14 17:25:59 vliang Exp $ sql.bsq
rem MODIFIED
rem huagli 06/09/08 - add ddst.bsq
rem dvoss 01/03/07 - add dlmnr.bsq
rem rdecker 10/20/06 - create SYSAUX before running dplsql.bsq
rem jklein 08/01/05 - diag 11g - split-up into units
rem sdavidso 08/01/05 - add tranform_param type check info
rem MODIFIED后面是脚本更新记录
第一列rem注释
第二列应该是更改人
第三列更改时间
第四列是备注，基本都是更改了什么内容
rem and 'default$' not-supported (N/S))
rem skrishna 12/06/94 - create extent table of pre-defined types
rem varora 12/01/94 - change toid in adtcol$ to type number
rem anori 11/17/94 - ADT support tables and columns

rem !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! IMPORTANT !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
rem Whenever new column is created to store internal, user or kernel column
rem number, be sure to update the structure adtDT in atb.c so that those
rem columns will be updated properly during drop column.
