因为工作需要在Oracle 11gR2库中新建一数据库实例。采用脚本命令创建，建议使用oracle用户进行以下操作。顺序如下：1.创建实例启

startup nomount pfile="/u01/oracle/product/11.2.0.1/db1/dbs/initcrm.ora";

CREATE DATABASE "crm"

MAXINSTANCES 8

MAXLOGHISTORY 1

MAXLOGFILES 16

MAXLOGMEMBERS 3

MAXDATAFILES 100

DATAFILE '/u01/oracle/oradata/system01.dbf' SIZE 1024M REUSE

EXTENT MANAGEMENT LOCAL

SYSAUX DATAFILE '/u01/oracle/oradata/sysaux01.dbf' SIZE 500M REUSE

SMALLFILE DEFAULT TEMPORARY TABLESPACE TEMP TEMPFILE '/u01/oracle/oradata/temp01.dbf' SIZE 20M REUSE

SMALLFILE UNDO TABLESPACE "UNDOTBS1" DATAFILE '/u01/oracle/oradata/undo01.dbf' SIZE 300M REUSE

CHARACTER SET ZHS16GBK

NATIONAL CHARACTER SET AL16UTF16

LOGFILE GROUP 1 ('/u01/oracle/oradata/log01.dbf') SIZE 50M,

GROUP 2 ('/u01/oracle/oradata/log02.dbf') SIZE 50M,

GROUP 3 ('/u01/oracle/oradata/log03.dbf') SIZE 50M;

创建USERS表空间

CREATE SMALLFILE TABLESPACE "USERS" LOGGING DATAFILE '/u01/app/oradata/user01.dbf' SIZE 1000M REUSE EXTENT MANAGEMENT LOCAL SEGMENT SPACEMANAGEMENT AUTO;

ALTER DATABASE DEFAULT TABLESPACE "USERS";

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

SQL> create spfile from pfile;

File created.

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

sqlplus / as sysdba

SQL> show user;

@/u01/oracle/product/11.2.0.1/db1/rdbms/admin/catalog.sql;

@/u01/oracle/product/11.2.0.1/db1/rdbms/admin/catblock.sql;

@/u01/oracle/product/11.2.0.1/db1/rdbms/admin/catproc.sql;

@/u01/oracle/product/11.2.0.1/db1/rdbms/admin/catoctk.sql;

@/u01/oracle/product/11.2.0.1/db1/rdbms/admin/owminst.plb;

使用system用户编译

@/u01/oracle/product/11.2.0.1/db1/sqlplus/admin/pupbld.sql;

@/u01/oracle/product/11.2.0.1/db1/sqlplus/admin/help/hlpbld.sql helpus.sql;

使用sys用户编译

@/u01/oracle/product/11.2.0.1/db1/javavm/install/initjvm.sql;

@/u01/oracle/product/11.2.0.1/db1/xdk/admin/initxml.sql;

@/u01/oracle/product/11.2.0.1/db1/xdk/admin/xmlja.sql;

@/u01/oracle/product/11.2.0.1/db1/rdbms/admin/catjava.sql;

@/u01/oracle/product/11.2.0.1/db1/rdbms/admin/catexf.sql;

@/u01/oracle/product/11.2.0.1/db1/rdbms/admin/catqm.sql change_on_install SYSAUX TEMP YES;

@/u01/oracle/product/11.2.0.1/db1/rdbms/admin/catxdbj.sql;

@/u01/oracle/product/11.2.0.1/db1/rdbms/admin/catrul.sql;

spool /oracle/admin/edidb/scripts/ordinst.log append

@/u01/oracle/product/11.2.0.1/db1/ord/admin/ordinst.sql SYSAUX SYSAUX;

spool off

spool /u01/oracle/admin/ora11g/scripts/interMedia.log append

@/u01/oracle/product/11.2.0.1/db1/ord/im/admin/iminst.sql;

spool off

set echo on

spool /oracle/admin/edidb/scripts/lockAccount.log append

BEGIN

FOR item IN ( SELECT USERNAME FROM DBA_USERS WHERE ACCOUNT_STATUS IN ('OPEN', 'LOCKED', 'EXPIRED') AND USERNAME NOT IN (

'SYS','SYSTEM') )

LOOP

dbms_output.put_line('Locking and Expiring: ' || item.USERNAME);

execute immediate 'alter user ' ||

sys.dbms_assert.enquote_name(

sys.dbms_assert.schema_name(

item.USERNAME),false) || ' password expire account lock' ;

END LOOP;

END;

/

spool off

到此，数据库实例建立完毕。

6.配置tns与listenser/u01/oracle/product/11.2.0.1/db1/network/admin/下

tnsnames.ora

CRM = (DESCRIPTION =

(ADDRESS_LIST = (ADDRESS =

(PROTOCOL = TCP) (HOST = 127.0.0.1)(PORT = 1521)

)

)

(CONNECT_DATA = (SERVICE_NAME = crm)

)

)

listener.ora监听方式有多种，要求不高的话建议复用原监听，，好处是变动小，缺点是不同实例公用监听，可能会不方便。

listener.ora

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(SID_NAME = orcl)

(ORACLE_HOME = /u01/oracle/product/11.2.0.1/db1)

(PROGRAM = extproc)

)

(SID_DESC =

(GLOBAL_DBNAME = crm)

(ORACLE_HOME = /u01/oracle/product/11.2.0.1/db1)

(SID_NAME = crm)

) )

单配监听：
