Oracle 11g R2 手动建库(create database manually)

1、设置环境变量.bash_profile
--确保至少包含下列环境变量，对于已经安装好Oracle Database software的情形下，实际上可以跳过此步骤
 $ vi .bash_profile
 export ORACLE_SID=catadb
 export ORACLE_BASE=/u01/app/oracle
 export ORACLE_HOME=$ORACLE_BASE/db_1
 export PATH=/usr/sbin:$PATH
 export PATH=$ORACLE_HOME/bin:$PATH
 export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
 export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

2、创建参数文件(位置:$ORACLE_HOME/dbs)
 [oracle@linux1 dbs]$ export ORACLE_SID=catadb
 [oracle@linux1 ~]$ cd $ORACLE_HOME/dbs
 [oracle@linux1 dbs]$ grep -v \# init.ora >init$ORACLE_SID.ora

 [oracle@linux1 dbs]$ more initcatadb.ora 
 db_name='catadb'
 memory_target=512M
 processes = 150
 audit_file_dest='/u03/uat/catadb/adump'
 audit_trail ='db'
 db_block_size=8192
 db_domain=''
 db_recovery_file_dest='/u03/uat/catadb/fr_area'
 db_recovery_file_dest_size=2G
 diagnostic_dest='/u03/uat/catadb'
 dispatchers='(PROTOCOL=TCP) (SERVICE=ORCLXDB)'
 open_cursors=300 
 remote_login_passwordfile='EXCLUSIVE'
 undo_tablespace='UNDOTBS1'
 control_files = ('/u03/uat/catadb/oradata/catadb01.ctl','/u03/uat/catadb/oradata/catadb02.ctl')
 compatible ='11.2.0'

3、创建目录结构 
 [oracle@linux1 ~]$ mkdir -p /u03/uat/catadb
 [oracle@linux1 dbs]$ cd /u03/uat/catadb
 [oracle@linux1 catadb]$ mkdir adump diag fr_area oradata

4、执行建库脚本 
 [oracle@linux1 catadb]$ more create_catadb.sql 
 create database catadb
 maxlogfiles 5
 maxlogmembers 5
 maxdatafiles 100
 maxinstances 1
 logfile
 group 1 ('/u03/uat/catadb/oradata/redo1.log') size 10m,
 group 2 ('/u03/uat/catadb/oradata/redo2.log') size 10m,
 group 3 ('/u03/uat/catadb/oradata/redo3.log') size 10m
 datafile
 '/u03/uat/catadb/oradata/system.dbf' size 200m reuse
 sysaux datafile '/u03/uat/catadb/oradata/sysaux.dbf' size 100m
 default tablespace user
 datafile '/u03/uat/catadb/oradata/userdata.dbf' size 100m
 undo tablespace undotbs1
 datafile '/u03/uat/catadb/oradata/undo1.dbf' size 100m
 default temporary tablespace temp1
 tempfile '/u03/uat/catadb/oradata/temp01.dbf'
 size 100m reuse
 character set al32utf8
 ;

 idle> @/u03/uat/catadb/create_catadb.sql
