[oracle部署实施]基于centos7.5、oracle11g r2手工建库过程

已提前最小化安装centos7.5和oracle 11g r2裸数据库软件，记录下手工建库过程，方便了解dbca建库原理。

1.环境变量设置

#设置环境变量

cat >> /home/oracle/.bash_profile <<eof

export oracle_base=/u01/app/oracle

export oracle_home=/u01/app/oracle/product/11.2.0/db_1

export oracle_sid=std1

export path=$oracle_home/bin:/sbin:/usr/sbin:$path

eof

source /home/oracle/.bash_profile

#设置命令别名

cat >> /home/oracle/.bashrc <<eof

alias dbn='cd $oracle_home/network/admin'

alias dbs='cd $oracle_home/dbs'

alias sql='sqlplus / as sysdba'

eof

source /home/oracle/.bashrc

#设置sqlplus环境

cat >> $oracle_home/sqlplus/admin/glogin.sql <<eof

define _editor='vi'

set sqlprompt "_user'@'_connect_identifier> "

set time on

set timing on

set pagesize 40

set linesize 120

eof

2.创建所需目录

mkdir -p $oracle_base/admin/std1/adump && mkdir -p $oracle_base/oradata/std1 && mkdir -p $oracle_base/flash_recovery_area

3.生成密码文件

dbn

orapwd file=orapwstd1 password=oracle entries=3

4.创建pfile参数文件

cat init.ora | grep -v ^# | grep -v ^$ > initstd1.ora

 

%s/orcl/std1/g

%s/orcl/std1/g

%s#<oracle_base>#$oracle_base/g

%s#ora_control1#/u01/app/oracle/oradata/std1/ora_control1.ctl#g

%s#ora_control2#/u01/app/oracle/oradata/std1/ora_control2.ctl#g

db_name='std1'

memory_target=1g

processes = 150

audit_file_dest='$oracle_base/admin/std1/adump'

audit_trail ='db'

db_block_size=8192

db_domain=''

db_recovery_file_dest='$oracle_base/flash_recovery_area'

db_recovery_file_dest_size=2g

diagnostic_dest='$oracle_base'

dispatchers='(protocol=tcp) (service=std1xdb)'

open_cursors=300

remote_login_passwordfile='exclusive'

undo_tablespace='undotbs1'

control_files = (/u01/app/oracle/oradata/std1/ora_control1.ctl,/u01/app/oracle/oradata/std1/ora_control2.ctl)

compatible ='11.2.0'

5.生成spfile参数文件

mount -o remount,size=4g /dev/shm    

 

sqlplus / as sysdba

startup nomount

create spfile from pfile;

6.执行创建数据库语句

vi crtdb.sql

 

create database std1

   user sys identified by oracle

   user system identified by oracle

   logfile group 1 ('/u01/app/oracle/oradata/std1/redo01a.log','/u01/app/oracle/oradata/std1/redo01b.log') size 100m blocksize 512,

           group 2 ('/u01/app/oracle/oradata/std1/redo02a.log','/u01/app/oracle/oradata/std1/redo02b.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/std1/system01.dbf' size 325m reuse

   sysaux datafile '/u01/app/oracle/oradata/std1/sysaux01.dbf' size 325m reuse

   default tablespace users

      datafile '/u01/app/oracle/oradata/std1/users01.dbf'

      size 500m reuse autoextend on maxsize unlimited

   default temporary tablespace tempts1

      tempfile '/u01/app/oracle/oradata/std1/temp01.dbf'

      size 20m reuse

   undo tablespace undotbs1

      datafile '/u01/app/oracle/oradata/std1/undotbs01.dbf'      size 200m reuse autoextend on maxsize unlimited;

 

@crtdb.sql

7.生成数据字典

vi crtdic.sql

 

@?/rdbms/admin/catalog.sql

@?/rdbms/admin/catproc.sql

conn system/oracle

@?/sqlplus/admin/pupbld.sql

exit

 

@crtdic.sql

8.检查一哈

select * from v$version;
