ORACLE的幾點學習經驗

常用的四個進程: 
OracleOraHome90Agent
OracleOraHome90HTTPServer
OracleOraHome90TNSListener
OracleServiceOR90

 

修改日期格式：
SQL> alter session set nls_date_format='yyyy-mm-dd hh:mi:ss';

create public database link ANALYSE  connect TO sa IDENTIFIED BY sa using  'ANALYSE';

select * from A_title@ANALYSE

要從網絡入口進入時必須修改的兩個文件:
D:/oracle/ora90/network/ADMIN
----TNSNAMES.ORA
ANALYSE=
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = cxh)(PORT = 1521))
    )
    (CONNECT_DATA =
 (SID = tg4msql)
 (SERVER = DEDICATED)
    )
    (HS = OK )
  )

-----LISTENER.ORA
    (SID_DESC =
      (GLOBAL_DBNAME = tg4msql)
      (ORACLE_HOME = c:/oracle/ora90)
      (SID_NAME = tg4msql)
      (PROGRAM = tg4msql)
    )
