篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了数据库迁移expdp impdp 与 OGg 搭建相关的知识，希望对你有一定的参考价值。
1.long 字段的无法使用OGG 同步
2.clob字段的导入导出Bug , 生产使用network-link 导入导出太慢了，本地导入导出速度会快3到4倍 。但是测试环境的情况却相反
测试环境和生产环境测试结果如下： 最后还是以生产环境的数据为主。
原因有2点，第一 ： 测试环境的网络没有拥塞，所以感觉测试环境network-link I/O 速度可以接受。第二测试环境的I/O 太慢了，跟生产环境不是一个等量级，所以感觉生产环境 本地I/O 会快很多。
数据局迁移遇到的Bug
1.DRAFT_LOG 这个表有6G ，有clob 字段
2．_LOG 这张表因为有clob 字段，这张表是核心表，导出时间和导入时间会有比较长。大概有19G ，
因为有clob 字段，导出时间会比较长。根据我们测试，
测试1：（测试环境），不使用network_link 方式，
EXPDP 这2张表时间会达到3个小时。
IMPDP 这2张表时间也会超过3个小时。
测试２: (测试环境) ，使用network_link 方式，
时间会缩短一倍，达到3个半小时。
测试３：（生产环境），使用network_link 方式，
从上午11点25发起，持续到16点，已经跑了4个半小时，还在导入。
测试4: (生产环境) ，使用本地导入导出方式，不使用network_link 方式，除去BAK_RGCT_DRAFT_LOG这个6G表。
EXPDP 所有生产用户时间会达到1个小时10分钟。
IMPDP 所有生产用户时间会达到1个小时10分钟。
可以在2个半小时左右完成，
1.
检查项 "1.创建空库不需要初始化
2.检查生产的FRA空间检查
生产的在维护期间会创建一个回滚点并保留7天，所以要检查灾备FRA的卷空间是否能保留7天的日志量。不足需申请扩空间。"
新建目标空库 "1，只包含system,sysaux,undotbs1,temp,users 表空间，不需要初始化。
set line 200 pagesize 200
select tablespace_name from dba_tablespaces a
where (a.tablespace_name not in (‘TEMP‘,‘SYSAUX‘,‘SYSTEM‘,‘USERS‘)
and a.contents not in (‘TEMPORARY‘,‘UNDO‘)) ;
2，字符集、block size与源库保持一致
select * from v$nls_parameters where parameter=‘NLS_CHARACTERSET‘;
show parameter block_size;
3，安装组件和源生产一致。
select comp_name,version,status from dba_registry order by 1;
4.源库和目标库具有相同的timeone；
SELECT VERSION FROM V$TIMEZONE_FILE;
8.db_cache_size
设置为和源库相同
show parameter db_cache_size
9.注：9.1.目标库cpu_count 不要在spfile里进行设置，不需要和源库保持一致
9.2.目标库的parallel_max_servers设置要和源库一致。
10.job_queue_processes，aq_tm_processes 设置为0。
11.修改新建的目标库为非归档模式
12，11g数据库参数按标准新建库手册。
13. 关闭Flashback。
select flashback_on from v$database; --结果为NO
15.awr配置为间隔15分钟，保留90天
exec dbms_workload_repository.modify_snapshot_settings(interval=>15, retention=>90*24*60);
col SNAP_INTERVAL format a20
col RETENTION format a20
select * from dba_hist_wr_control;"
检查迁移对象是否是闭包的 "1：检查迁移用户引用非迁移用户的对象，如果引用的是系统表酌情处理；如果引用的是非系统表则要整改。
select * from dba_dependencies dd where dd.owner in
(‘BBSP‘,‘BBSPODS‘,‘BCDPETL‘,‘DBMONOPR‘,‘DBMGR‘,‘OVSEE‘) --替换为实际用户
and dd.referenced_owner not in
(‘BBSP‘,‘BBSPODS‘,‘BCDPETL‘,‘DBMONOPR‘,‘DBMGR‘,‘OVSEE‘)
2：检查非迁移用户引用迁移用户的对象，如果存在则与开发讨论处理方法。
select * from dba_dependencies dd where dd.type<>‘SYNONYM‘ and dd.owner not in
(‘BBSP‘,‘BBSPODS‘,‘BCDPETL‘,‘DBMONOPR‘,‘DBMGR‘,‘OVSEE‘) ----替换为实际用户
and dd.referenced_owner in
(‘BBSP‘,‘BBSPODS‘,‘BCDPETL‘,‘DBMONOPR‘,‘DBMGR‘,‘OVSEE‘) ----替换为实际用户
/"
检查迁移schema的trigger是否是闭包的 "1:检查触发器的owner<>table_owner且owner不在迁移用户列表而table_owner在迁移用户列表的情况，这种触发器需要手工迁移
select * from dba_triggers where owner<>table_owner and owner not in (‘BBSP‘,‘BBSPODS‘,‘BCDPETL‘,‘DBMONOPR‘,‘DBMGR‘,‘OVSEE‘) and table_owner in (‘BBSP‘,‘BBSPODS‘,‘BCDPETL‘,‘DBMONOPR‘,‘DBMGR‘,‘OVSEE‘) ;
2:检查触发器的owner<>table_owner且owner在迁移用户列表而table_owner不在迁移用户列表的情况，这种触发器视情况决定是否迁移
select * from dba_triggers where owner<>table_owner and owner not in (‘BBSP‘,‘BBSPODS‘,‘BCDPETL‘,‘DBMONOPR‘,‘DBMGR‘,‘OVSEE‘) and table_owner in (‘BBSP‘,‘BBSPODS‘,‘BCDPETL‘,‘DBMONOPR‘,‘DBMGR‘,‘OVSEE‘) ;
3:检查触发器的triggering_eventowner‘LOGON ‘且owner在迁移用户列表或table_owner在迁移用户列表的情况，这种触发器expdp不能导出需要手工迁移
select * from dba_triggers where triggering_event=‘LOGON ‘and (owner in (‘BBSP‘,‘BBSPODS‘,‘BCDPETL‘,‘DBMONOPR‘,‘DBMGR‘,‘OVSEE‘) or table_owner in (‘BBSP‘,‘BBSPODS‘,‘BCDPETL‘,‘DBMONOPR‘,‘DBMGR‘,‘OVSEE‘));
"
根据10g生产库中待迁移job清单信息，生成job迁移脚本并在测试环境验证通过。特别注意：脚本所有待迁移job其next_date都必须设为无限大。 t_update_status();
检查10g生产库中是否有业务scheduler存在，这些scheduler也要进行迁移，如果存在有，本步要把迁移scheduler的脚本准备好 0
"
创建11g目标库到10g生产库的dblink" "create public database link dblink_migup connect to dbmgr identified by &pw
using ‘ 生产库连接串 ‘;
3:验证dblink是否通
select * from [email protected]_migup; --有结果返回表示通的否则不通需处理
"
"
1. 创建要迁移的用户清单配置表(sys..t_user_cfg)
" "create table sys.t_user_cfg as SELECT username, default_tablespace
FROM [email protected]_migup
WHERE username not in
(‘SYS‘, ‘SYSTEM‘, ‘PUBLIC‘, ‘OUTLN‘, ‘WMSYS‘, ‘ORDSYS‘, ‘MDSYS‘,

‘SPATIAL_CSW_ADMIN_USR‘, ‘APEX_PUBLIC_USER‘, ‘XS$NULL‘,‘DMSYS‘)
minus
select username, default_tablespace from dba_users;"
目标端新增表空间 "1.查看源库表空间名称及大小，在目标库新建相同大小表空间
set line 200 pagesize 200
select tablespace_name from dba_tablespaces a
where a.tablespace_name not in (‘TEMP‘,‘SYSAUX‘,‘SYSTEM‘,‘USERS‘) ;
--注意临时表空间是否有特殊的，CREATE TEMPORARY TABLESPACE RLMSTMP TEMPFILE ‘+DATA_HDG‘ SIZE 100M AUTOEXTEND ON;
2.打开所有表空间的自动扩展
select ‘alter database datafile ‘‘‘||file_name||‘‘‘ autoextend on next 100M;‘ from dba_data_files ;
select ‘alter database tempfile ‘‘‘||file_name||‘‘‘ autoextend on next 100M;‘ from dba_temp_files ;
执行上面生成的脚本
复核：
select df.tablespace_name,df.autoextensible from dba_temp_files df where df.autoextensible=‘NO‘;
select df.tablespace_name,df.autoextensible from dba_data_files df where df.autoextensible=‘NO‘;"
目标端创建role "SET termout OFF feedback OFF verify OFF echo OFF heading OFF trims ON escape ON pages 0 linesize 999 long 3000
spool $HOME/01_create_role.sql
select ‘create role ‘ || role || ‘;‘
from (select role
from [email protected]_migup
minus
select role from dba_roles);
spool off;
在目标库执行01_create_role.sql"
创建密码函数 "执行附件脚本创建密码函数sys.VERIFY_FUNCTION_11G
PS:这个密码函数如果老库的名称不一样，需要把老库的函数迁移过来。"
创建profile "SET termout OFF feedback OFF verify OFF echo OFF heading OFF trims ON escape ON pages 0 linesize 999 long 3000
spool $HOME/02_deal_profile.sql
select (case
when rn = 1 then
(‘create profile ‘ || profile ||‘ limit ‘ || resource_name ||‘ ‘ || limit || (case
when rn = max_rn then
‘;‘
end)) else(resource_name || ‘ ‘ || limit || (case
when rn = max_rn then
‘;‘
end)) end)
from (select profile,
resource_name,
limit,
row_number() over(partition by profile order by profile, resource_name) rn,
count(*) over(partition by profile) max_rn
from [email protected]_migup
where profile in
(select distinct profile
from [email protected]_migup
minus
select distinct profile from dba_profiles)
order by profile, resource_name)
order by profile, resource_name;
spool off;
执行02_deal_profile.sql
alter profile default limit PASSWORD_VERIFY_FUNCTION VERIFY_FUNCTION_11G;
alter profile default limit FAILED_LOGIN_ATTEMPTS 10;
复核：
select * from dba_profiles minus select * from [email protected]_migup;
select * from [email protected]_migup minus select * from dba_profiles;"
创建公共同义词 "SET termout OFF feedback OFF verify OFF echo OFF heading OFF trims ON escape ON pages 0 linesize 999 long 3000
spool $HOME/03_create_public_synonym.sql
SELECT
‘create or replace public synonym ‘||synonym_name||‘ for ‘||table_owner||‘.‘||table_name||‘;‘

2.unzip goldengate软件
" 请注意 goldengate 软件区分os平台和oracle版本 ,另外对于RAC，goldengate软件安装目录需要设置为共享存储
"cd
