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dblink
1.1 旧库修改tnsname到新库，在新库上添加旧库的tns配置
SQL> !tnsping fzcbdb9i Used TNSNAMES adapter to resolve the alias Attempting 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$instance; select instance_name,status from v$instance@t_s_link;
3.数据量大小对比
dba_segments SQL> select sum(bytes)/1024/1024/1024 as size_g from dba_segments; SIZE_G ---------- 7420.62244 SQL> select sum(bytes)/1024/1024/1024 as size_g from dba_segments@t_s_link; SIZE_G ---------- 8972.52301
4.用户对比
4.1创建用户对比
select username from all_users order by created;
select username 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', 'OUTLN', 'SYSTEM', 'CTXSYS', 'DBSNMP', 'LOGSTDBY_ADMINISTRATOR', 'ORDSYS', 'ORDPLUGINS', 'OEM_MONITOR', 'WKSYS', 'WKPROXY', 'WK_TEST', 'WKUSER', 'MDSYS', 'LBACSYS', 'DMSYS', 'WMSYS', 'EXFSYS', 'SYSMAN', 'MDDATA', 'SI_INFORMTN_SCHEMA', 'XDB', 'ODM') GROUP BY OWNER; SELECT OWNER, COUNT(*) FROM DBA_OBJECTS@t_s_link WHERE OWNER NOT IN ( 'SYS', 'OUTLN', 'SYSTEM', 'CTXSYS', 'DBSNMP', 'LOGSTDBY_ADMINISTRATOR', 'ORDSYS', 'ORDPLUGINS', 'OEM_MONITOR', 'WKSYS', 'WKPROXY', 'WK_TEST', 'WKUSER', 'MDSYS', 'LBACSYS', 'DMSYS', 'WMSYS', 'EXFSYS', 'SYSMAN', 'MDDATA', 'SI_INFORMTN_SCHEMA', 'XDB', 'ODM') GROUP BY OWNER;
