创建表空间:

create tablespace "FZXT_DATA_TEST"
logging
datafile 'D:\OracleEx\oradata\fzxt\fzxt.dbf' 
size 100m 
autoextend on 
next 1m extent management local;

创建用户并分配权限:
create user fzxt_test identified by "fzxt_test" default tablespace FZXT_DATA_TEST;
grant resource,connect to fzxt_test;
grant select any table to fzxt_test;
grant select any dictionary to fzxt_test;
grant create any trigger,create any view,create table to fzxt_test;
grant exp_full_database,imp_full_database,resource,create any sequence to fzxt_test;


导出数据:(实例)
exp userid=fzxt/fzxt@fzxt_13 file=./fzxt.dmp log=./dmp.log owner=fzxt


导导入数据库:(实例)
imp fzxt_test/fzxt_test fromuser=fzxt touser=fzxt_test statistics=none file=fzxt.dmp ignore=y log=./imp.log

fromuser就是把当前的dmp文件中的某一个用户下的数据取出。

touser就是把现在dmp文件中的数据导入到目标库的指定user下。

70B model, 1000 tokens can be generated in seconds, which translates into nearly 4000 characters! The researchers fine-tuned Llama3 and introduced an acceleration algorithm. Compared with the native version, the speed is 13 times faster! Not only is it fast, its performance on code rewriting tasks even surpasses GPT-4o. This achievement comes from anysphere, the team behind the popular AI programming artifact Cursor, and OpenAI also participated in the investment. You must know that on Groq, a well-known fast inference acceleration framework, the inference speed of 70BLlama3 is only more than 300 tokens per second. With the speed of Cursor, it can be said that it achieves near-instant complete code file editing. Some people call it a good guy, if you put Curs
