手工建库

一：操作步骤

---1:手工建库 官方文档位置
----Database Administration---》Administrator's Guide----》2 Creating and Configuring an Oracle Database


----1、Specify an Instance Identifier (SID)
  prod
----2、建立目录，在$ORACLE_BASE/admin/下建立$ORACLE_SID的目录，再创建子目录/adump（存储审计文件的目录），/dpdump

/u01/app/oracle/admin/prod/{a,dp}dump
/u01/app/oracle/fast_recovery_area/{prod,PROD}
----建立目录，在$ORACLE_BASE/oradata/下建立$ORACLE_SID的目录
/u01/app/oracle/oradata/prod

----3、设置oracle用户环境变量实例名为prod
export ORACLE_SID=prod

----4、创建参数文件
cat $ORACLE_HOME/dbs/init.ora |grep -v ^# >initprod.ora

vi initprod.ora

db_name='prod'
memory_target=512M
processes = 150
audit_file_dest='/u01/app/oracle/admin/prod/adump'
audit_trail ='db'
db_block_size=8192
db_domain=''
db_recovery_file_dest='/u01/app/oracle/fast_recovery_area'
db_recovery_file_dest_size=4182M
diagnostic_dest='/u01/app/oracle'
dispatchers='(PROTOCOL=TCP) (SERVICE=ORCLXDB)'
open_cursors=300
remote_login_passwordfile='EXCLUSIVE'
undo_tablespace='UNDOTBS1'
control_files = ('/u01/app/oracle/oradata/prod/control01.ctl','/u01/app/oracle/oradata/prod/control02.ctl','/u01/app/oracle/oradata/prod/control03.ctl')
compatible ='11.2.0.4'

----5、创建密码文件
orapwd file=orapwprod password=oracle

----6、启动实例(NOMOUNTT状态)
startup nomount

----7、运行建库脚本
CREATE DATABASE prod
   LOGFILE GROUP 1 ('/u01/app/oracle/oradata/prod/redo01.log') SIZE 100M,
           GROUP 2 ('/u01/app/oracle/oradata/prod/redo02.log') SIZE 100M,
           GROUP 3 ('/u01/app/oracle/oradata/prod/redo03.log') SIZE 100M
   MAXLOGFILES 50
   MAXLOGMEMBERS 5
   MAXLOGHISTORY 10
   MAXDATAFILES 100
   MAXINSTANCES 1
   CHARACTER SET US7ASCII
   NATIONAL CHARACTER SET AL16UTF16
   DATAFILE '/u01/app/oracle/oradata/prod/system01.dbf' SIZE 325M REUSE   EXTENT MANAGEMENT LOCAL
   SYSAUX DATAFILE '/u01/app/oracle/oradata/prod/sysaux01.dbf' SIZE 325M REUSE  DEFAULT TABLESPACE users
   DATAFILE '/u01/app/oracle/oradata/prod/users01.dbf' SIZE 100M REUSE  DEFAULT TEMPORARY TABLESPACE tempts
      TEMPFILE '/u01/app/oracle/oradata/prod/temp01.dbf' SIZE 20M REUSE
   UNDO TABLESPACE undotbs1
      DATAFILE '/u01/app/oracle/oradata/prod/undotbs01.dbf' SIZE 200M REUSE AUTOEXTEND ON MAXSIZE UNLIMITED;

----8、运行创建数据字典脚本
创建数据字典视图
SQL> @?/rdbms/admin/catalog.sql
创建PL/SQL的软件包和过程
SQL> @?/rdbms/admin/catproc.sql
SQL>@$ORACLE_HOME/sqlplus/admin/pupbld.sql

二：具体实验：

1：创建有些文件目录。

[root@localhost ~]# su - oracle
---进入oracle base目录
[oracle@localhost ~]$ cd /u01/app/oracle/
[oracle@localhost oracle]$ pwd
/u01/app/oracle
[oracle@localhost oracle]$ ls
admin  cfgtoollogs  checkpoints  diag  fast_recovery_area  oradata  product
--进入admin目录 
[oracle@localhost oracle]$ cd admin
[oracle@localhost admin]$ ls
orcl
---创建新的SID :neworcl
[oracle@localhost admin]$ mkdir neworcl
[oracle@localhost admin]$ ls
neworcl  orcl
[oracle@localhost admin]$

[oracle@localhost admin]$


[oracle@localhost admin]$ pwd
/u01/app/oracle/admin
[oracle@localhost admin]$ ls
neworcl  orcl
[oracle@localhost admin]$ cd neworcl/
[oracle@localhost neworcl]$ mkdir dpdump
[oracle@localhost neworcl]$ mkdir adump
[oracle@localhost neworcl]$ ls
adump  dpdump
---adump 存放的是审计信息
--dpdump 存放的是：主要是数据泵的一个目录
[oracle@localhost neworcl]$ ls ../orcl
adump  dpdump  pfile  wallet
[oracle@localhost neworcl]$

---切换$ORACLE_BASE 目录下
[oracle@localhost neworcl]$ cd ..
[oracle@localhost admin]$ ls
neworcl  orcl
[oracle@localhost admin]$ cd ..
[oracle@localhost oracle]$ ls
admin  cfgtoollogs  checkpoints  diag  fast_recovery_area  oradata  product
[oracle@localhost oracle]$

###在 闪回恢复区  fast_recovery_area   文件夹中创建2个文件夹 neworcl  NEWORCL 
[oracle@localhost oracle]$ ls
admin  cfgtoollogs  checkpoints  diag  fast_recovery_area  oradata  product
[oracle@localhost oracle]$ cd fast_recovery_area/
[oracle@localhost fast_recovery_area]$ ls
orcl  ORCL
[oracle@localhost fast_recovery_area]$ pwd
/u01/app/oracle/fast_recovery_area
[oracle@localhost fast_recovery_area]$ mkdir NEWORCL
[oracle@localhost fast_recovery_area]$ ls
NEWORCL  orcl  ORCL
[oracle@localhost fast_recovery_area]$ mkdir neworcl
[oracle@localhost fast_recovery_area]$ ls
neworcl  NEWORCL  orcl  ORCL
[oracle@localhost fast_recovery_area]$ pwd
/u01/app/oracle/fast_recovery_area
[oracle@localhost fast_recovery_area]$

###在 oradate 目录下 创建 neworcl 目录 
[oracle@localhost fast_recovery_area]$ pwd
/u01/app/oracle/fast_recovery_area
[oracle@localhost fast_recovery_area]$ cd ..
[oracle@localhost oracle]$ pwd
/u01/app/oracle
[oracle@localhost oracle]$ ls
admin  cfgtoollogs  checkpoints  diag  fast_recovery_area  oradata  product
[oracle@localhost oracle]$ cd oradata/
[oracle@localhost oradata]$ ls
orcl  PROD1
[oracle@localhost oradata]$ mkdir neworcl
[oracle@localhost oradata]$ ls
neworcl  orcl  PROD1
[oracle@localhost oradata]$

##创建目的是用来存放：数据文件和日志文件和控制文件
[oracle@localhost oradata]$ pwd
/u01/app/oracle/oradata
[oracle@localhost oradata]$ cd neworcl/
[oracle@localhost neworcl]$ pwd
/u01/app/oracle/oradata/neworcl
[oracle@localhost neworcl]$

2：指定数据库的ORACLE_SIE=neworcl

[oracle@localhost neworcl]$ exp
exp     expand  expdp   expdpO  expO    export  expr

[oracle@localhost neworcl]$ export ORACLE_SID=neworcl

[oracle@localhost neworcl]$ echo $ORACLE_SID         

neworcl

[oracle@localhost neworcl]$

3: 创建一个参数文件 initneworcl.ora 并创建口令文件 orapwneworcl 及其数据用户密码为 oracle

##切换到oracle的家目录
[oracle@localhost neworcl]$ cd ../../product/11.2.0/db_1/dbs/
[oracle@localhost dbs]$ pwd
/u01/app/oracle/product/11.2.0/db_1/dbs
[oracle@localhost dbs]$

# 利用init.oracl 文件来创建 initneworcl.ora 初始化参数文件
[oracle@localhost dbs]$ ls
dbsorapwPROD1  hc_orcl.dat  hc_PROD1.dat  init.ora  initorcl.ora  initPROD1.ora  lkORCL  lkPROD1  my.dbf  orapworcl  spfileorcl.ora  spfilePROD1.ora  tem.dbf
[oracle@localhost dbs]$ cat init.ora | grep -v ^# > initneworcl.ora
[oracle@localhost dbs]$ ls
dbsorapwPROD1  hc_PROD1.dat     init.ora      initPROD1.ora  lkPROD1  orapworcl       spfilePROD1.ora
hc_orcl.dat    initneworcl.ora  initorcl.ora  lkORCL         my.dbf   spfileorcl.ora  tem.dbf
[oracle@localhost dbs]$

#修改 neworcl 的静态参数文件信息： initneworcl.ora
[oracle@localhost dbs]$ vi initneworcl.ora

[oracle@localhost dbs]$ cat initneworcl.ora

#指定数据库名称
db_name='NEWORCL'
#指定数据库内存大小
memory_target=300m
#指定数据库进程数
processes = 150
#指定数据库审计的位置
audit_file_dest='/u01/app/oracle/admin/neworcl/adump'
#指定审计的级别： db 为数据库级别 
audit_trail ='db'
#指定数据库块的大小
db_block_size=8192
#数据库域的名称
db_domain=''
#闪回恢复区的位置
db_recovery_file_dest='/u01/app/oracle/fast_recovery_area'
#闪回恢复区的大小 
db_recovery_file_dest_size=2G
#adi 的目录 ；组件的资料库
diagnostic_dest='/u01/app/oracle'
# 协议
dispatchers='(PROTOCOL=TCP) (SERVICE=ORCLXDB)'
#游标的个数
open_cursors=300
#使用口令文件的方式
remote_login_passwordfile='EXCLUSIVE'
#undo 表空间的名称 
undo_tablespace='UNDOTBS1'
#控制文件：
control_files = ('/u01/app/oracle/fast_recovery_area/neworcl/control01.ctl','/u01/app/oracle/oradata/neworcl/control02.ctl')
#数据库版本 
compatible ='11.2.0.3.0'
[oracle@localhost dbs]$

#创建口令文件  orapwneworcl
[oracle@localhost dbs]$ ls
dbsorapwPROD1  hc_PROD1.dat     init.ora      initPROD1.ora  lkPROD1  orapworcl       spfilePROD1.ora
hc_orcl.dat    initneworcl.ora  initorcl.ora  lkORCL         my.dbf   spfileorcl.ora  tem.dbf
[oracle@localhost dbs]$ orapwd file=orapwneworcl password=oracle
[oracle@localhost dbs]$ ls
dbsorapwPROD1  hc_PROD1.dat     init.ora      initPROD1.ora  lkPROD1  orapwneworcl  spfileorcl.ora   tem.dbf
hc_orcl.dat    initneworcl.ora  initorcl.ora  lkORCL         my.dbf   orapworcl     spfilePROD1.ora
[oracle@localhost dbs]$

4:处理数据库启动的时候：ORA-01078, LRM-00123错误；原因是：

原来在initneworcl.ora 的文件, 我自己在注释部分加入了中文.

不能有中文呀, 连注释都不行.

同时修改了 initneworcl.ora 文件的数据库名称为小写

[oracle@localhost dbs]$ rlwrap sqlplus / as sysdba;
