以下是对新建Oracle数据库的三种方法进行了详细的分析介绍,,需要的朋友可以过来参考下

 

1.通过运行Oracle Database Configuration  Assistant 创建、配置、或删除数据库(也可在命令行下输入dbca);
2.用命令行的方式建立数据库
3.通过运行自定义的批处理脚本(或create_ORACLE_SID.bat(create_ORACLE_SID.sql))来创建、配置、或删除数据库。

详述:
1.通过运行Oracle Database Configuration Assistant 创建、配置、或删除数据库;
建议不熟悉创建过程的DBA使用该方法,只需要根据选项“下一步”进行配置,最后生成数据库的创建脚本(建议保留),或者直接创建数据库;
优点:GUI方法使用方便;
缺点:不过创建过程有些慢;

2.用命令行的方式建立数据库

复制代码 代码如下:


CONNECT / AS SYSDBA
  STARTUP PFILE= 'C:oracleadmininit_testorcl.ora' NOMOUNT;
  CREATE DATABASE testOrcl DATAFILE '/u02/oracle/testOrcl/system01.dbf' SIZE 100M
  LOGFILE GROUP1 ('/u01/oracle/testOrcl/redo1a.log',
  '/u02/oracle/testOrcl/redo1b.log') SIZE 500K,
  GROUP2 ('/u01/oracle/testOrcl/redo1a.log',
  '/u02/oracle/testOrcl/redo1b.log') SIZE 500K
  CHARACTER SET ZHS16CGB231280;

--将数据库直接从未建置状态转换到打开状态
  ALTER DATABASE OPEN;

--删除数据库(Dropping a Database)
  SPOOL C:DROP_DATABASE.BAT
  SELECT 'DEL '||NAME 删除数据库相关数据文件 FROM V$DATAFILE;
  SELECT 'DEL '||MEMBER 删除数据重构日志文件 FROM V$LOGFILE;
  SPOOL OFF;


优点:可以熟悉创建指令,创建原理;
缺点:配置简单,要求熟记命令行指令;
 
3.通过运行自定义的批处理或SQL脚本(create_ORACLE_SID.bat或create_ORACLE_SID.sql)来创建

复制代码 代码如下:


--create_ORACLE_SID.bat
  set ORACLE_SID= ORACLE_SID.
del  C:ORACLE8IdatabasepwdORACLE_SID.ora
  C:ORACLE8Ibinoradim -new -sid ORACLE_SID. -intpwd oracle -startmode manual
  -pfile C:ORACLE8IadminORACLE_SIDpfileinit.ora
  C:ORACLE8Ibinsvrmgrl @C:WINNTProfilesAdministratorLbORACLE_SIDrun.sql
  C:ORACLE8Ibinsvrmgrl @C:WINNTProfilesAdministratorLbORACLE_SIDrun1.sql
  C:ORACLE8Ibinoradim -edit -sid ORACLE_SID -startmode auto

--ORACLE_SIDrun.sql
  spool C:ORACLE8IadminORACLE_SIDcreatecreatedb
  set echo on
  connect INTERNAL/oracle
  startup nomount pfile=C:ORACLE8IadminORACLE_SIDpfileinit.ora
  CREATE DATABASE ORACLE_SID
  LOGFILE 'C:ORACLE8IoradataORACLE_SIDredo01.log' SIZE 1024K,
  'C:ORACLE8IoradataORACLE_SIDredo02.log' SIZE 1024K
  MAXLOGFILES 32
  MAXLOGMEMBERS 2
  MAXLOGHISTORY 1
  DATAFILE 'C:ORACLE8IoradataORACLE_SIDsystem01.dbf' SIZE 50M REUSE
  MAXDATAFILES 254
  MAXINSTANCES 1
  CHARACTER SET ZHT16BIG5
  NATIONAL CHARACTER SET ZHT16BIG5;
  spool off

--ORACLE_SIDrun1.sql
  spool C:ORACLE8IadminORACLE_SIDcreatecreatedb1
  set echo on
  connect INTERNAL/oracle
ALTER DATABASE DATAFILE 'C:ORACLE8IoradataORACLE_SIDsystem01.dbf' AUTOEXTEND ON;
  CREATE ROLLBACK SEGMENT SYSROL TABLESPACE "SYSTEM" STORAGE (INITIAL  100K NEXT 100K);
  ALTER ROLLBACK SEGMENT "SYSROL" ONLINE;


Linux平台下Oracle的操作

下面对Oracle的操作都是在Linux平台下进行的!
1.su Oracle
2.sqlplus /logon
3.connect test/test assysdba(test/test是Oracle用户和密码)
4.startup
5.lsnrctl
首选启动数据库
su - Oracle
sqlplus /nolog
conn /as sysdba
startup
然后启动监听:
进入/opt/Oracle/product/9.2.0/bin/
lsnrctl start
运行shudown命令关闭数据库
[Oracle@wing /Oracle]$ sqlplus" / as sysdba" //以sysdba用户登陆数据库
SQL> shutdown

启动Oracle 9i 数据库
[Oracle@wing bin]$ sqlplus " /as sysdba"
SQL> startup

启动Oracle 9i监听程序
Oracle的监听程序主要是为客户端的连接提供接口
[Oracle@wing bin]$ lsnrctl
LSNRCTL> start

关闭Oracle 9i监听程序
[Oracle@wing bin]$ lsnrctl
LSNRCTL> stop

先看看Oracle_SID 环境变量设置是否正确。
9i:
$ sqlplus /nolog
SQL> connect / as sysdba
SQL> startup
$ lsnrctl start
8i:
$ svrmgrl
SVRMGR> connect internal
SVRMGR> startup
$ lsnrctl start
在哪里报错??
一般只要设置这2处就好了~
/etc/oratab
ora2:/Oracle/app/Oracle/product/8.1.7:Y 
/etc/inittab
oralce:2:wait:/bin/su - Oracle -c '/Oracle/app/Oracle/product/8.1.7/bin/lsnrctl start'
Oracle:2:wait:/bin/su - Oracle -c '/Oracle/app/Oracle/product/8.1.7/bin/dbstart'

启动步骤:
su - Oracle
[Oracle@websvr1 Oracle]$ sqlplus /nolog
SQL> connect / as sysdba
SQL> startup
SQL> quit
[Oracle@websvr1 Oracle]$ lsnrctl start
可用 [Oracle@websvr1 Oracle]$ lsnrctl status 查看监听是否已经启动

Explain the InnoDB Buffer Pool and its importance for performance.Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.
