系统环境：
手工建库相对来说很容易实现，本案例是从10g和11g，通过手工建库的方式做一个简单的对比，可以看出11g和10g之间的一个简单的差异！
案例二：
在Oracle 11g 环境下手工建库
DB_NAME='test1'
INSTANCE_NAME='test1'
1、建立Instance的初始化参数文件和口令文件
[oracle@rh6 dbs]$cat inittest1.ora
db_name='test1'
memory_target=400m //Oracle 11g增加了内存自动管理
processes = 150
audit_file_dest='$ORACLE_BASE/admin/test1/adump'
audit_trail ='db'
db_block_size=8192
db_domain=''
open_cursors=300
remote_login_passwordfile='EXCLUSIVE'
undo_tablespace='UNDOTBS1'
# You may want to ensure that control files are created on separate physical
# devices
control_files = /u01/app/oracle/oradata/test1/control01.ctl
compatible ='11.2.0'
[oracle@rh6 dbs]$ orapwd file=orapwtest1 password=oracle entries=3
2、建立数据库相关的目录
Oracle 11g增加了diagnostic directory，默认的为$ORACLE_BASE
[oracle@rh6 dbs]$ mkdir -p $ORACLE_BASE/admin/test1/adump
[oracle@rh6 dbs]$ mkdir -p /u01/app/oracle/oradata/test1
3、建立建库脚本
[oracle@rh6 ~]$ cat cr_db.sql
CREATE DATABASE test1
USER SYS IDENTIFIED BY oracle
USER SYSTEM IDENTIFIED BY oracle
LOGFILE
GROUP 1 ('/u01/app/oracle/oradata/test1/redo01a.log') SIZE 50M ,
GROUP 2 ('/u01/app/oracle/oradata/test1/redo02a.log') SIZE 50M
MAXLOGFILES 10
MAXLOGMEMBERS 5
MAXLOGHISTORY 1
MAXDATAFILES 200
CHARACTER SET zhs16gbk
DATAFILE '/u01/app/oracle/oradata/test1/system01.dbf' SIZE 325M REUSE
SYSAUX DATAFILE '/u01/app/oracle/oradata/test1/sysaux01.dbf' SIZE 325M REUSE
DEFAULT TEMPORARY TABLESPACE tempts1
TEMPFILE '/u01/app/oracle/oradata/test1/temp01.dbf'
SIZE 100M REUSE
UNDO TABLESPACE undotbs1
DATAFILE '/u01/app/oracle/oradata/test1/undotbs01.dbf'
SIZE 200M REUSE AUTOEXTEND ON MAXSIZE UNLIMITED;
4、启动Instance并建立数据库
[oracle@rh6 ~]$ export ORACLE_SID=test1
[oracle@rh6 ~]$ sqlplus '/as sysdba'
