手动创建Oracle实例

背景：

手动创建Oracle实例

手工建库步骤

Step 1: Specify an Instance Identifier (SID)（指定一个实例的标识符SID）
Step 2: Ensure That the Required Environment Variables Are Set（确认环境变量的设置）
Step 3: Choose a Database Administrator Authentication Method（决定数据库管理员的认证方法）
Step 4: Create the Initialization Parameter File(创建初始化的参数文件信息)
Step 5: (Windows Only) Create an Instance
Step 6: Connect to the Instance（连接实例）
Step 7: Create a Server Parameter File（创建spfile）
Step 8: Start the Instance(启动实例)
Step 9: Issue the CREATE DATABASE Statement（创建DATABASE的语句）
Step 10: Create Additional Tablespaces（创建额外的表空间）
Step 11: Run Scripts to Build Data Dictionary Views（运行脚本创建数据库字典视图）
Step 12: (Optional) Run Scripts to Install Additional Options
Step 13: Back Up the Database.
Step 14: (Optional) Enable Automatic Instance Startup

Step 1: Specify an Instance Identifier (SID)（指定一个实例的标识符SID）
export Oracle_SID=lenovo
echo $ORACLE_SID

mkdir -p /u01/app/oracle/admin/lenovo/adump
orapwd file="/u01/app/oracle/product/11.2.0/dbhome_1/dbs/orapwLENOVO" password=oracle entries=30
Step 2: Ensure That the Required Environment Variables Are Set（确认环境变量的设置）
[oracle@RedHat3 lenovo]$ mkdir datafile
[oracle@redhat3 lenovo]$ mkdir redolog
[oracle@redhat3 lenovo]$ pwd
/u01/app/oracle/oradata/lenovo
[oracle@redhat3 ~]$ cat .bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
 . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH

#Oracle Settings
export TMP=/tmp
export TMPDIR=/tmp
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
export ORACLE_SID=lenovo
export ORACLE_TERM=xterm
export PATH=/usr/sbin:$PATH
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib:/usr/local/lib:/usr/X11R6/lib/
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
export LANG=C
umask 022

alias date='date +%Y-%m-%d%t%A%t%T '

Step 3: Choose a Database Administrator Authentication Method（决定数据库管理员的认证方法）
[oracle@redhat3 bin]$ pwd
/u01/app/oracle/product/11.2.0/db_1/bin
[oracle@redhat3 bin]$ orapwd file=orapwdlenovo password=oracle entries=30

Step 4: Create the Initialization Parameter File(创建初始化的参数文件信息)
[oracle@redhat3 dbs]$ cat initlenovo.ora
db_name='LENOVO'
memory_target=808M
control_files = ('/u01/app/oracle/oradata/lenovo/controlfile/control01.ctl')

Step 6: Connect to the Instance（连接实例）
[oracle@redhat3 dbs]$ echo $ORACLE_SID
lenovo
[oracle@redhat3 dbs]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.4.0 Production on Tue Nov 1 19:28:17 2016

Step 7: Create a Server Parameter File（创建spfile）
SQL> create spfile from pfile='/u01/app/oracle/product/11.2.0/db_1/dbs/initlenovo.ora';

Step 8: Start the Instance(启动实例)
SQL> startup nomount
ORACLE instance started.

Step 9: Issue the CREATE DATABASE Statement（创建DATABASE的语句）
create_db.sql
