Linux下以命令行方式新建oracle数据库实例

承接上次所说，数据库创建好了之后，新建一个数据库实例caacdb。

一、Create database

---------------------------------------------

1. create log dir

$ mkdir -p $ORACLE_BASE/admin/$ORACLE_SID

$ cd $ORACLE_BASE/admin/$ORACLE_SID

$ mkdir adump bdump cdump dpdump hdump pfile udump

2. init file

$ORACLE_BASE/admin/$ORACLE_SID/pfile/init.ora

3. create oracle password file

$ orapwd file=$ORACLE_HOME/dbs/orapw$ORACLE_SID password=oracle

4. create database

$ sqlplus /nolog

SQL> conn / as sysdba;

SQL> startup nomount pfile="/opt/app/oracle/admin/caacdb/pfile/init.ora";

SQL>

CREATE DATABASE caacdb

MAXINSTANCES 8

MAXLOGHISTORY 16

MAXLOGFILES 16

MAXLOGMEMBERS 3

MAXDATAFILES 512

DATAFILE '/opt/app/oracle/oradata/caacdb/system01.dbf' SIZE 2048M REUSE

AUTOEXTEND OFF

EXTENT MANAGEMENT LOCAL

AUTOEXTEND OFF

LOGFILE GROUP 1 ('/opt/app/oracle/oradata/caacdb/redo01.log') SIZE 102400K,

GROUP 2 ('/opt/app/oracle/oradata/caacdb/redo02.log') SIZE 102400K,

GROUP 3 ('/opt/app/oracle/oradata/caacdb/redo03.log') SIZE 102400K

USER SYS IDENTIFIED BY "ora"

USER SYSTEM IDENTIFIED BY "ora";

SQL> @?/rdbms/admin/catalog.sql;

SQL> @?/rdbms/admin/catblock.sql;

SQL> @?/rdbms/admin/catproc.sql;

SQL> @?/rdbms/admin/catoctk.sql;

SQL> conn system/oracle;

SQL> @?/sqlplus/admin/pupbld.sql;

SQL> @?/sqlplus/admin/help/hlpbld.sql helpus.sql;

5. Add default user tablespace

SQL> conn sys/oracle as sysdba;

SQL> CREATE SMALLFILE TABLESPACE USERS

LOGGING

DATAFILE '/opt/app/oracle/oradata/caacdb/users01.dbf' SIZE 1000M REUSE

AUTOEXTEND OFF

EXTENT MANAGEMENT LOCAL

SEGMENT SPACE MANAGEMENT AUTO;

SQL> ALTER DATABASE DEFAULT TABLESPACE USERS;

6. Create spfile

SQL> create spfile from pfile='/opt/app/oracle/admin/caacdb/pfile/init.ora';

SQL> shutdown immediate;

7. set listener port to other (1521)

$ORACLE_HOME/network/admin/listener.ora

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(SID_NAME = PLSExtProc)

(ORACLE_HOME = /opt/app/oracle/product/10.2.0/db_1)

(PROGRAM = extproc)

)

(SID_DESC =

(GLOBAL_DBNAME = caacdb)

(ORACLE_HOME = /opt/app/oracle/product/10.2.0/db_1)

(SID_NAME = caacdb)

)

)

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))

(ADDRESS = (PROTOCOL = TCP)(HOST =0.0.0.0)(PORT = 1521))

)

)

$ sqlplus /nolog

SQL> alter system set local_listener="(ADDRESS = (PROTOCOL = TCP)(HOST = 0.0.0.0)(PORT = 1521))" scope=spfile;

二、Set archive log mode

-----------------------------------------

1. Set Parameter

SQL> alter system set log_archive_format = 'caacdb_%r_%T_%S.ARC' scope=spfile;

**********************************

%s log sequence number

%S log sequence number, zero filled

%t thread number

%T thread number, zero filled

%a activation ID

%d database ID

%r resetlogs ID that ensures unique names are constructed for the archived log files across multiple incarnations of the database

**********************************

SQL> alter system set log_archive_dest_1 = 'LOCATION=USE_DB_RECOVERY_FILE_DEST' scope=spfile;

SQL> alter system set log_archive_dest_2 = 'LOCATION=/oracle/arch/caacdb' scope=spfile;

2. Switch log mode

SQL> shutdown immediate;

SQL> startup mount;

SQL> alter database archivelog;

SQL> alter database open;

SQL> archive log list;

3. Test archive log

SQL> alter system switch logfile;

SQL> alter system switch logfile;

SQL> alter system switch logfile;

SQL> show parameter db_recovery_file_dest

NAME TYPE VALUE

------------------------------------ ----------- ------------------------------

db_recovery_file_dest string /oracle/flush_area/caacdb

db_recovery_file_dest_size big integer 2G

$ ls /oracle/arch/caacdb

caacdb_685304034_0001_0000000008.ARC

caacdb_685304034_0001_0000000010.ARC

caacdb_685304034_0001_0000000009.ARC

$ ls -R /oracle/flush_area/caacdb/

/oracle/flush_area/caacdb:

caacdb

/oracle/flush_area/caacdb/caacdb:

archivelog

/oracle/flush_area/caacdb/caacdb/archivelog:

2009_04_27

/oracle/flush_area/caacdb/caacdb/archivelog/2009_04_27:

o1_mf_1_10_4zc8jy8t_.arc o1_mf_1_8_4zc8jg2w_.arc o1_mf_1_9_4zc8jlnd_.arc

三、开启服务

1. 启动数据库：

sqlplus/ as sysdba (连接实例)

startup (启动数据库)

2. 启动监听：

lsnrctl start

验证数据库实例及监听状态：
