以前在听播布客小布老师视频的时候，学习了手工建库, oacle 创建数据库一般都是使用dbca ，通过脚本建库给自己在创建数据库上多了一种选择。
手工建库步骤
Choose a unique instance and database name
Choose a database character set
Set a operating system variable
Create the initialization parameter file
Start the instance in NOMOUNT stage
Create and Excetue the CREATE DATABASE commond
Run scripts to generate the data dictionary and accomplish post-creation setps
Create addtitional tablespaces as needed
1 ) CHOOSE A UNIQUE SID AND DATABASE CHARACTER 和相关目录
1 2 3 4
*.db_name ='MANUA' CHARACTER SET ZHS16GBK NATIONAL CHARACTER SET AL16UTF16 mkdir /oradata/MANUAL mkdir $ORACLE_BASE /admin/MANUA cd MANUA mkdir adump bdump cdump dpdump pfile udump
2 ) 用orapwd命令创建密码文件
1
orapwd file =$ORACLE_HOME /dbs/orapwMANUA password =MANUA20 entries =10
注意:需要创建密码文件,否则只能通过操作系统论证,远程Oracle客户端不能连接.
3) 准备环境变量
1 2 3 4 5 6
exprt ORACLE_BASE =/app/oracle export ORACLE_HOME =$ORACLE_BASE /product/10gexport ORACLE_SID =MANUAexport ORA_NLS33 =$ORACLE_HOME /ocommon/nls/admin/dataexport LD_LIBRARY_PATH =$ORACLE_HOME /lib:/lib:/usr/libexport LD_LIBRARY_PATH =$ORACLE_HOME /lib:$LD_LIBRARY_PATH
4) 准备初始化参数
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21
[oracle@standby dbs]$ cat initMANUA.ora *.audit_file_dest ='/app/oracle/admin/MANUA/adump' *.background_dump_dest ='/app/oracle/admin/MANUA/bdump' *.control_files ='/oradata/MANUA/control01.ctl' ,'/oradata/MANUA/control02.ctl','/oradata/MANUA/control03.ctl' *.core_dump_dest ='/app/oracle/admin/MANUA/cdump' *.db_block_size =8192 *.db_domain ='' *.db_file_multiblock_read_count =16 *.db_name ='MANUA' *.dispatchers ='(PROTOCOL=TCP) (SERVICE=MANUAXDB)' *.job_queue_processes =10 *.open_cursors =300 *.pga_aggregate_target =103936000 *.processes =150 *.remote_login_passwordfile ='EXCLUSIVE' *.sga_max_size =251225472 *.sga_target =221225472 *.undo_management ='AUTO' *.undo_tablespace ='UNDOTBS1' *.user_dump_dest ='/app/oracle/admin/MANUA/udump'
5) 创建数据库
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
oradim -NEW -SID monitor1 oradim -DELETE -SID OSS Startup nomount;CREATE DATABASE CMTT81CONTROLFILE REUSE USER SYS IDENTIFIED BY CMTT81155USER SYSTEM IDENTIFIED BY CMTT81155LOGFILE GROUP 1 ('/dev/vg01/rlvredolog11' , '/dev/vg01/rlvredolog12' ) SIZE 512 M, GROUP 2 ('/dev/vg01/rlvredolog21' , '/dev/vg01/rlvredolog22' ) SIZE 512 M, GROUP 3 ('/dev/vg01/rlvredolog31' , '/dev/vg01/rlvredolog32' ) SIZE 512 M, GROUP 4 ('/dev/vg01/rlvredolog41' , '/dev/vg01/rlvredolog42' ) SIZE 512 M, GROUP 5 ('/dev/vg01/rlvredolog51' , '/dev/vg01/rlvredolog52' ) SIZE 512 M, GROUP 6 ('/dev/vg01/rlvredolog61' , '/dev/vg01/rlvredolog62' ) SIZE 512 M MAXLOGFILES 6 MAXLOGMEMBERS 5 MAXLOGHISTORY 1 MAXDATAFILES 1000 MAXINSTANCES 1 CHARACTER SET UTF8NATIONAL CHARACTER SET UTF8DATAFILE '/dev/vg01/rCMTT81_system_01.dbf' SIZE 3130 M AUTOEXTEND OFF SYSAUX DATAFILE '/dev/vg01/rCMTT81_sysaux_01.dbf' SIZE 3130 M AUTOEXTEND OFF DEFAULT TEMPORARY TABLESPACE temp TEMPFILE '/dev/vg01/rCMTT81_temp_01.dbf' SIZE 5140 M AUTOEXTEND OFF UNDO TABLESPACE UNDOTBS1 DATAFILE '/dev/vg01/rCMTT81_undo_01.dbf' SIZE 10240 M AUTOEXTEND OFF ;
6) 导入数据字典
1 2 3
@?/rdbms /admin /catalog .sql ; @?/rdbms /admin /catproc .sql ; @?/sqlplus /admin /pupbld .sql ; --system 用户执行
附一：查自动扩展
1 2 3 4 5 6 7
col file_name format a50; alter database datafile 1 autoextend off ;alter database datafile 2 autoextend off ;alter database datafile 3 autoextend off ;alter database tempfile 1 autoextend off ;select file_name,file_id,autoextensible ,bytes /(1024 *1024 *1024 )G from dba_data_files where autoextensible='YES' ;select file_name,file_id,autoextensible,bytes /(1024 *1024 *1024 )G From dba_temp_files;
附二：手工建库DBCA找不到解决方法
vi /etc/oratab
1
MANUA :/app/oracle/product/ 10 g: N
然后在运行dbca就能看到了！
