正在看的ORACLE教程是:oracle初始化参数设置。 ALTER DATABASE
DATAFILEd:\ORANT\DATABASE\USER1ORCL.ORA RESIZE 1000M;
CREATE TABLESPACE INDEX_DATA DATAFILEd:\ORANT\DATABASE\INDEX_DATA
SIZE 500M;
ALTER DATABASE DATAFILEd:\ORANT\DATABASE\RBS1ORCL.ORA RESIZE 300M;
ALTER DATABASE DATAFILEd:\ORANT\DASTABASE\TMP1ORCL.ORA RESIZE 300M;

Segmentation: group customers based on similar needs, and determine the characteristics of customers in thoses segments

Targeting: asses attractiveness of each segment, and select segments that the firm wants to fucus on for its products or services

drop rollback segment “RB1”;
drop rollback segment “RB2”;
drop rollback segment “RB3”;
drop rollback segment “RB4”;
drop rollback segment “RB5”;
drop rollback segment “RB6”;
drop rollback segment “RB7”;
drop rollback segment “RB8”;
drop rollback segment “RB9”;
drop rollback segment “RB10”;
drop rollback segment “RB11”;
drop rollback segment “RB12”;
drop rollback segment “RB13”;
drop rollback segment “RB14”;
drop rollback segment “RB15”;
drop rollback segment “RB16”;

Positioning: formulate the firm’s value proposition for target segments

create rollback segment “RB1” tablespace “ROLLBACK_DATA” storage
(initial 1m next 1m);
create rollback segment “RB2” tablespace “ROLLBACK_DATA” storage
(initial 1m next 1m);
create rollback segment “RB3” tablespace “ROLLBACK_DATA” storage
(initial 1m next 1m);
create rollback segment “RB4” tablespace “ROLLBACK_DATA” storage
(initial 1m next 1m);
create rollback segment “RB5” tablespace “ROLLBACK_DATA” storage
(initial 1m next 1m);
create rollback segment “RB6” tablespace “ROLLBACK_DATA” storage
(initial 1m next 1m);
