orcale最大連接數，創建EDW表空間，用戶創建，授權

安裝完成後

D:\app\Administrator\product\11.2.0\dbhome_1\NETWORK\ADMIN\tnsnames.ora
修改裏面的loalhost改爲對應的IP

修改密碼效期

ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED

修改數據庫最大連接數

select count(*) from v$process --當前的連接數

select value from v$parameter where name = 'processes' --數據庫允許的最大連接數

修改最大連接數:
alter system set processes = 300 scope = spfile;

重啓數據庫:
shutdown immediate;
startup;

oracle創建表的四種方式

create bigfile tablespace SPACE_BASE datafile
    'C:\app\xiulong\oradata\edw\SPACE_BASE.dbf' size 2048m autoextend on next 100m maxsize unlimited;
create bigfile tablespace SPACE_EDW datafile 
    'C:\app\xiulong\oradata\edw\SPACE_EDW.dbf' size 2048m autoextend on next 100m maxsize unlimited;
create bigfile tablespace SPACE_DM datafile 
    'C:\app\xiulong\oradata\edw\SPACE_DM.dbf' size 2048m autoextend on next 100m maxsize unlimited;
create bigfile tablespace SPACE_INDEX datafile 
    'C:\app\xiulong\oradata\edw\space_index.dbf' size 2048m autoextend on next 100m maxsize unlimited;

本機連接虛擬機，記得關閉防火牆

測試的話就是相互ping一下
netsh firewall set opmode mode=disable關閉虛擬機防火牆

EDW用戶創建，授權

create user INMON identified by "jhsz0603" default tablespace SPACE_BASE
 temporary tablespace TEMP
  profile DEFAULT;

-- Grant/Revoke role privileges 
grant aq_administrator_role to INMON with admin option;
grant dba to INMON with admin option;
grant mgmt_user to INMON;

-- Grant/Revoke system privileges 
grant create materialized view to INMON;
grant create table to INMON;
grant global query rewrite to INMON;
grant select any table to INMON;
grant unlimited tablespace to INMON with admin option;
