1. 安装Linux AS4.5
2. 安装Oracle database 11g software
3. Create database manually
    3.1 Set environment variables
    [oracle@localhost ~]$ vi .bash_profile
     # .bash_profile

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

    # User specific environment and startup programs
    HOSTNAME=$(uname -n)
    PS1='(${?})${LOGNAME}@${HOSTNAME}:${ORACLE_SID:-"NO_SID"}:${PWD}
$ '
    PS2='> '
    # Set Global variables
    set -o vi
    set VISUAL=vi
    set EDITOR=vi
    set PAGER=more
    # Set local variables
    export ORACLE_BASE=/u01/app/oracle
    export ORACLE_HOME=$ORACLE_BASE/product/11.1.0/db_1
    export ORACLE_SID=orcl
    export JAVA_HOME=/usr/java5
    export PATH=$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:$JAVA_HOME/bin:$PATH:$HOME/bin
    unset USERNAME

    3.2 Create user and group by root
    # groupadd oinstall
    # groupadd dba
    # useradd -g oinstall -G dba oracle

   3.3 Create directories
    $./create_directory.ksh
   -----create_directory.ksh-----
    #!/bin/ksh
    mkdir -p /data/oradata/orcl
    mkdir -p /indx/oradata/orcl
    mkdir -p /redo01/oradata/orcl
    mkdir -p /redo02/oradata/orcl
    mkdir -p /bakup/flash_recovery_area
    mkdir -p /bakup/rman/orcl
    mkdir -p /u01/app/oracle/admin/orcl
    cd /u01/app/oracle/admin/orcl
    mkdir adump pfile script. create utl
    chown -R oracle:oinstall /data /indx /redo01 /redo02 /bakup /u01/app/admin

    3.4 Create pfile and password file
    3.4.1 create pfile
    $ cd /u01/app/oracle/admin/orcl/pfile
    $ vi initorcl.ora

4. Create database script
    $sqlplus / as sysdba

5. Create spfile
     SQL> create spfile from pfile;
     (0)oracle@liang:orcl:/u01/app/oracle/product/11.1.0/db_1/dbs
     $ ls
     hc_orcl.dat  initdw.ora  init.ora  initorcl.ora  lkORCL  orapworcl  spfileorcl.ora

6. Enable archivelog and flashback features
    SQL> show parameter db_recovery_file_dest
    NAME                                 TYPE        VALUE
    ------------------------------------ ----------- ------------------------------
    db_recovery_file_dest                string      /bakup/flash_recovery_area

    Automatic archival             Disabled
    Archive destination            USE_DB_RECOVERY_FILE_DEST
    Oldest online log sequence     1   
    Current log sequence           3

    SQL> shutdown immediate
    SQL> startup mount
    SQL> alter database archivelog;
    SQL> alter database flashback on;
    SQL> alter database open;

    SQL> archive log list;

    NAME                                 TYPE        VALUE
    ------------------------------------ ----------- ------------------------------
    db_flashback_retention_target        integer     1440

7. Create additional tablespace
    SQL> create tablespace app_tbs
    datafile '/data/oradata/orcl/app_tbs01.dbf' SIZE 10M
    AUTOEXTEND ON NEXT 5M MAXSIZE 100M
    EXTENT MANAGEMENT LOCAL;

   SQL> create tablespace indx_tbs
    datafile '/indx/oradata/orcl/indx_tbs01.dbf' SIZE 10M
    AUTOEXTEND ON NEXT 5M MAXSIZE 100M
    EXTENT MANAGEMENT LOCAL;
   
8. Run Scripts to build dictionary views
    RUN catalog.sql and catproc.sql by sys user
    SQL> @$ORACLE_HOME/rdbms/admin/catalog.sql
    SQL> @$ORACLE_HOME/rdbms/admin/catproc.sql
