环境：RHEL6.4 + Oracle 11.2.0.4
　　一、创建数据库catdb
　　1.1 官档的建库脚本示例
CREATE DATABASE mynewdb
USER SYS IDENTIFIED BY sys_password
USER SYSTEM IDENTIFIED BY system_password
LOGFILE GROUP 1 ('/u01/logs/my/redo01a.log'，'/u02/logs/my/redo01b.log') SIZE 100M BLOCKSIZE 512，
GROUP 2 ('/u01/logs/my/redo02a.log'，'/u02/logs/my/redo02b.log') SIZE 100M BLOCKSIZE 512，
GROUP 3 ('/u01/logs/my/redo03a.log'，'/u02/logs/my/redo03b.log') SIZE 100M BLOCKSIZE 512
MAXLOGFILES 5
MAXLOGMEMBERS 5
MAXLOGHISTORY 1
MAXDATAFILES 100
CHARACTER SET US7ASCII
NATIONAL CHARACTER SET AL16UTF16
EXTENT MANAGEMENT LOCAL
DATAFILE '/u01/app/oracle/oradata/mynewdb/system01.dbf' SIZE 325M REUSE
SYSAUX DATAFILE '/u01/app/oracle/oradata/mynewdb/sysaux01.dbf' SIZE 325M REUSE
DEFAULT TABLESPACE users
DATAFILE '/u01/app/oracle/oradata/mynewdb/users01.dbf'
SIZE 500M REUSE AUTOEXTEND ON MAXSIZE UNLIMITED
DEFAULT TEMPORARY TABLESPACE tempts1
TEMPFILE '/u01/app/oracle/oradata/mynewdb/temp01.dbf'
SIZE 20M REUSE
UNDO TABLESPACE undotbs
DATAFILE '/u01/app/oracle/oradata/mynewdb/undotbs01.dbf'
SIZE 200M REUSE AUTOEXTEND ON MAXSIZE UNLIMITED;
　　1.2 根据我实际环境修改如下项
　　sys_password -> oracle
　　system_password -> oracle
　　US7ASCII -> ZHS16GBK
　　mynewdb -> catdb
　　/u01/logs/my -> /u01/redologs/a
　　/u02/logs/my -> /u01/redologs/b
　　/u01/app/oracle/oradata -> /u01/oradata03
　　可以vi批量替换，比如:%s#/u01/logs/my#/u01/redologs/a#g替换所有/u01/logs/my为/u01/redologs/a。
　　修改完如下:
vi /home/oracle/create_db.sql
CREATE DATABASE catdb
USER SYS IDENTIFIED BY oracle
USER SYSTEM IDENTIFIED BY oracle
LOGFILE GROUP 1 ('/u01/redologs/a/redo01a.log'，'/u01/redologs/b/redo01b.log') SIZE 100M BLOCKSIZE 512，
GROUP 2 ('/u01/redologs/a/redo02a.log'，'/u01/redologs/b/redo02b.log') SIZE 100M BLOCKSIZE 512，
GROUP 3 ('/u01/redologs/a/redo03a.log'，'/u01/redologs/b/redo03b.log') SIZE 100M BLOCKSIZE 512
MAXLOGFILES 5
MAXLOGMEMBERS 5

MAXDATAFILES 100
