oracle11g创建新的用户和改动最大连接数

create user test identified by root;

grant create session,resource to root;

alter user test account unlock;

grant create view to test;

grant any sequece to test;

grant create synonym to ich;--创建别名的权限

drop user test cascade;

连接时用户民不区分大写和小写

alter system set sec_case_sensitive_logon=false scope=both;

commit;

改动用户password

alter user system identified by system; 

在用户1中建立的sequece test_seq假设想在用户2中使用(select test_seq.nextval from dual)必须如今用户2中运行select test_seq.nextval from dual;

oracle一个创建用户、创建表空间、授权、建表的完整过程

1. 用sys登录sql plus:



    usename: sys as sysdba



    password: ****



2. 查看最大连接数： select value from V$parameter where name="processes";



3. 查看当前连接数： select count (*) from V$process;



4. 把最大连接数改成300：alter system set processes=300 scope=spfile



5. 重新启动DB: shutdown immediate;



                 startup;
