怎么在aix环境下为oracle数据库新建一个实例, 比如test,并建立对应的用户(oracle数据库已经装好),十万火急!!
------解决方案--------------------
登录操作系统用dbca命令建立数据库,建好数据库后再建立用户
------解决方案--------------------
是数据库实例以装好，需要创建数据库吧。
在 图形界面下运行 dbca
------解决方案--------------------
./dbca
------解决方案--------------------
注：以下步骤只是一个参考实例，参考者注意修改参数值，比如用户名，SID,端口等，切记切记！！！
1． 创建数据库用户:ora_bill
useradd -d /LCdisk/oradata/bill -g dba ora_bill
root:/LCdisk/oradata/bill> passwd ora_bill
su – ora_bill
2． 创建环境变量ORACLE_SID=testbill;
3． 注意以下三个文件
创建文件
oracle:/home/oracle/product/9.2.0/dbs> more inittestacct.ora> inittestbill.ora
root:/home/oracle/product/9.2.0/dbs> chown ora_bill inittestbill.ora
修改该文件内容

修改以下文件
ora_bill:/home/oracle/product/9.2.0/network/admin> vi listener.ora
添加：
LISTENER3=
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.91)(PORT = 1521))
)
SID_LIST_LISTENER3 =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = testbill)
(ORACLE_HOME = /home/oracle/product/9.2.0)
(SID_NAME = testbill)
)
)
修改文件
ora_bill:/home/oracle/product/9.2.0/network/admin> vi tnsnames.ora
添加
TESTBILL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.91)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = testbill)
)
)
4． 创建目录
ora_bill:/LCdisk/oradata/bill/admin/udump>
ora_bill:/LCdisk/oradata/bill/admin/bdump>
ora_bill:/LCdisk/oradata/bill/admin/cdump>
root:/LCdisk/oradata/bill/admin> chown oracle *
root:/LCdisk/oradata/bill> chmod -R 777 admin
root:/LCdisk/oradata/bill/admin> su - ora_bill
5． 创建数据库实例
ora_bill:/LCdisk> sqlplus /nolog
SQL> conn / as sysdba
SQL> startup nomount
SQL> CREATE DATABASE TESTBILL
2 USER SYS IDENTIFIED BY hncs
