Oracle手动创建数据库
安装oracle客户端软件：root账户执行：#groupaddoinstall#groupadddba#useradd-goinstall-Gdbaoracle#passwdoracle创建oracle基本目录：#mkdir-p/u01/app/oracle
root账户执行：
#groupadd oinstall
#groupadd dba
#useradd -g oinstall -G dba oracle
#passwd oracle
#mkdir -p /u01/app/oracle
#chown -R oracle:oinstall /u01
#chmod -R 775 /u01
/u01 由根目录拥有。
/u01/app 由根目录拥有。
配置内核参数
#vi /etc/sysctl

kernel.shmall = 268435456
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536

安装客户端：
$vi ~/.bash_profile
export ORALCE_BASE=/u01/app/oracle
export ORALCE_HOME=$ORACLE_BASE/product/10.2.0/db_1
export ORALCE_SID=orcl
export PATH=$ORACLE_HOME/bin:$PATH
生效环境变量：
$source ~/.bash_profile
手动创建库：

创建数据库脚本文件：
dbca.sql

创建密码文件：
$orapwd file=$ORACLE_HOME/dbs/orapwdorcl password=tiger entries=10
创建数据库基本目录：
$mkdir -p /u01/app/oracle/admin/orcl/adump
$mkdir -p /u01/app/oracle/admin/orcl/bdump
$mkdir -p /u01/app/oracle/admin/orcl/udump
$mkdir -p /u01/app/oracle/admin/orcl/cdump
$mkdir -p /u01/app/oracle/flash_recovery_area
$mkdir -p /u01/app/oracle/arch
$mkdir -p /u01/app/oracle/oradata/orcl
#sqlplus "/ as sysdba"
#startup nomount pfile=/soft/initorcl.ora
创建表空间：
CONNECT SYS/password AS SYSDBA
-- create a user tablespace to be assigned as the default tablespace for users
CREATE TABLESPACE users LOGGING
DATAFILE '/u01/app/oracle/oradata/orcl/users01.dbf'
SIZE 25M REUSE AUTOEXTEND ON NEXT 1280K MAXSIZE UNLIMITED
EXTENT MANAGEMENT LOCAL;
-- create a tablespace for indexes, separate from user tablespace
CREATE TABLESPACE indx LOGGING
DATAFILE '/u01/app/oracle/oradata/orcl/indx01.dbf'
SIZE 25M REUSE AUTOEXTEND ON NEXT 1280K MAXSIZE UNLIMITED
EXTENT MANAGEMENT LOCAL;
alter database default tablespace users;
运行脚本：
CONNECT SYS/password AS SYSDBA
@/u01/app/oracle/product/10.2.0/db_1/rdbms/admin/catalog.sql
@/u01/app/oracle/product/10.2.0/db_1/rdbms/admin/catproc.sql
EXIT
