问题描述：需要对比用户数据一般在数据库迁移之后，需要对比一下两个库之间的差距，如果登上去一条命令的执行，去统计，就会比较麻烦，这里整理了一些脚本可用。通过创建dblink的方式快速查询，也可以整合到一个脚本中spool到一个文本中

 

1.创建dblink1.1 旧库修改tnsname到新库，在新库上添加旧库的tns配置

sql> !tnsPing fzcbdb9iUsed TNSnameS adapter to resolve the aliasAttempting to contact (DESCRIPTION = (ADDRESS = (PROTOCol = TCP)(HOST =10.136.7.208)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_name = fzcbdb)))OK (0 msec)

 

1.2  旧库创建有访问权限的用户

create user comp IDentifIEd by comp default tablespace USERS; grant connect,resource,dba to comp;

 

1.3 新库创建dblink到旧库

 

create database link t_s_link connect to comp IDentifIEd by comp using 'fzcbdb1';select count(*) from dba_tables@t_s_link;

 

 

2.实例查询

select instance_name,status from v$instance;from v$instance@t_s_link;

 

 

 

3.数据量大小对比

dba_segmentssql> select sum(bytes)/1024/1024 as size_g  dba_segments;    SIZE_G----------7420.62244sql>  dba_segments@t_s_link;    SIZE_G----------8972.52301

 

4.用户对比4.1创建用户对比

select username  all_users order by created;
from all_users@t_s_link order by created;

 

 

 

4.2用户下对象总数

SELECT OWNER,COUNT(*)  FROM DBA_OBJECTS WHERE OWNER NOT IN ( SYS',OUTLNSYstemCTXSYSDBSNMP,LOGSTDBY_adminISTRATORORDSYSORdplUGINSOEM_MONITORWKSYSWKPROXYWK_TESTWKUSERmdsYSLBACSYSDMSYSWMSYSEXFSYSSYSMANMDDATASI_INFORMTN_SCHEMAXDBODM) GROUP BY OWNER;SELECT OWNER,COUNT(*)  FROM DBA_OBJECTS@t_s_link WHERE OWNER NOT IN ( ) GROUP BY OWNER;

 

 

 

4.4用户对象类型

4.5单一用户对象对比

4.6单一用户表分区对比

4.7单一用户表分区数量对比
select count(0) '  and object_type=;';
 
 
4.8表分区详细对比

4.9无效对象

4.13用户对象权限，被赋予public用户的表

4.14用户权限

4.15段类型统计

4.16约束统计

5.db_link

6.public的同义词
 
set linesize 1000col SYNONYM_name format a40col table_name format a40select *   dba_synonyms where owner =    and table_OWNER );       dba_synonyms@t_s_link ');
 
 
7.自动任务统计
 
 
select job,LOG_USER,LAST_DATE,NEXT_DATE,INTERVAL,FAILURES,broKEN,WHAT  dba_jobs;from dba_jobs@t_s_link;
