手工创建数据库(myorcl)
export ORACLE_SID=myorcl
1.创建口令文件
orapwd file=$ORACLE_HOME/dbs/orapw$ORACLE_SID password=oracle
2.创建参数文件
vi $ORACLE_HOME/dbs/initmyorcl.ora
参数：
db_name=\'myorcl\'
compatible=11.2.0.4.0
age_target=1g
control_file=\'/u01/app/oracle/oradata/myorcl/control01.ctl\'
audit_file_dest=\'/u01/app/oracle/admin/myorcl/adump\'
diagnostic_dest=\'/u01/app/oracle\'
db_recovery_file_dest_size=4g
db_recovery_file_dest=\'/u01/app/oracle/fast_recovery_area\'
undo_tablespace=undo01
3.创建相关目录
mkdir -p /u01/app/oracle/oradata/myorcl
mkdir -p /u01/app/oracle/admin/myorcl/adump
mkdir -p /u01/app/oracle/fast_recovery_area
4.启动实例到nomount
sqlplus / as sysdba
把pfile转成spfile
create spfile from pfile;
startup nomount
5.创建数据库
create database myorcl
datafile \'/u01/app/oracle/oradata/myorcl/system01.dbf\' size 400m autoextend on next 64m extend management local
sysaux datafile \'/u01/app/oracle/oradata/myorcl/sysaux01.dbf\' size 100m autoextend on next 64m
umdo tablespace undo01 datafile \'/app/oracle/oradata/myorcl/undo01.dbf\' size 100m autoextend on next 64m
default tempoary tablespace temp tempfile \'/app/oracle/oradata/myorcl/temp01.dbf\' size 50m autoextend on
character set zhs16gbk
national character set al16utf16
logfile
group 1 \'/u01/app/oracle/oradata/myorcl/redo01.log\' size 50m,
group 2 \'/u01/app/oracle/oradata/myorcl/redo02.log\' size 50m,
group 3 \'/u01/app/oracle/oradata/myorcl/redo03.log\' size 50m;
6.创建数据字典，构造pl/sql运行环境
@?/rdbms/admin/catalog.sql
@?/rdbms/admin/catproc.sql
7.建立测试用户scott
@?/rdbms/admin/utlsampl.sql
conn system/manager
@?/sqlplus/admin/pupbld.sql
根据模板静默安装：
dbca -silent -createDatabase -templateName /u01/app/oracle/product/11.2.0/db_1/assistants/dbca/templates/General_Purpose.dbc -gdbName db01 -sid db01 -sysPassword oracle -systemPassword oracle -characterSet zhs16gbk -nationalCharacterSet al16utf16 -response NO_VALUE -datafileDestination /u01/app/oracle/oradata
