时间:2021-04-08 14:02:34   收藏:0   阅读:0

环境:
RAC1:192.168.56.111 (db版本:12.2.0.1)
RAC2:192.168.56.112 (db版本:12.2.0.1)
DG备库:192.168.56.19 (db版本:12.2.0.1) OGG源库
OGG目标库:192.168.56.166 (db版本:11.2.0.4) OGG目标库

 

 

1.停掉从库的复制进程,并删除dirdat目录下的内容
GGSCI (epidb01) 2> stop repep
epidb01-> cd dirdat
epidb01-> rm ep*

 

2.主库停掉并删除主库的抽取进程
stop extract dpep
stop extract extep
dblogin userid goldengate,password goldengate
delete extract dpep
delete extract extep

 

3.主库创建抽取和投递进程
GGSCI>edit params dpep
GGSCI>ADD EXTRACT dpep, EXTTRAILSOURCE ./dirdat/ep
GGSCI>ADD RMTTRAIL ./dirdat/ep, EXTRACT dpep, MEGABYTES 100
---dpep参数如下:

extract dpep
userid goldengate, password AACAAAAAAAAAAAKAPATACEHBIGQGCFZCCDIGAEMCQFFBZHVC ,ENCRYPTKEY DEFAULT
RmtHost 192.168.56.166, MgrPort 7819, Compress
RmtTrail ./dirdat/ep
gettruncates
Passthru
table hxl.*;

 

4.抽取进程
GGSCI>edit params extep
GGSCI>ADD EXTRACT extep, tranlog, begin now, threads 2 ##注意这里虽然dg是单节点的,但是dg的主库是rac环境的,这里必须写对应的节点数
GGSCI>ADD EXTTRAIL ./dirdat/ep, EXTRACT extep, megabytes 100

---extep参数如下:

extract extep
userid goldengate, password AACAAAAAAAAAAAKAPATACEHBIGQGCFZCCDIGAEMCQFFBZHVC ,ENCRYPTKEY DEFAULT
SETENV (ORACLE_SID="dg12c")
SETENV ( NLS_LANG = AMERICAN_AMERICA.ZHS16GBK)
exttrail ./dirdat/ep
BR BRINTERVAL 20M
numfiles 5000
warnlongtrans 3h, checkinterval 10m
TRANLOGOPTIONS LOGRETENTION ENABLED
--TRANLOGOPTIONS AltArchiveLogDest /u01/app/oracle/archive_log/
tranlogoptions minefromactivedg
--TRANLOGOPTIONS  ASMUSER sys@asmtns_rac01, ASMPASSWORD oracle
--TRANLOGOPTIONS DBLOGREADER

--DDL parameter

INCLUDE MAPPED OBJTYPE VIEW &
INCLUDE MAPPED OBJTYPE PROCEDURE &
INCLUDE MAPPED OBJTYPE FUNCTION &
INCLUDE MAPPED OBJTYPE PACKAGE 


--DDLOPTIONS ADDTRANDATA REPORT 

table hxl.tb_ogg_test;

 

6.删除掉主库上./dirdat目录下的ep开头的文件

[oracle@localhost dirdat]$ cd /goldengate12c/dirdat

[oracle@localhost dirdat]$ rm ep*

 

7.启动主库的抽取进程
start extep -- 主库
start dpep -- 主库

 

---------------------------------从库操作-------------------------

1.停掉监听器并杀掉ogg目标库用户下的进程

lsnrctl stop

Select Distinct
                alter system kill session    || ‘‘‘‘ || b.sid || , ||b.SERIAL# ||  ‘‘‘; kill_command,
                b.Username
  From Gv$sql a,
       Gv$session b,
       Gv$session_Wait c,
       Gv$latchholder d,
       Gv$locked_Object e,
       (Select lk.inst_id,Lk.Sid, Lk.Type, Lt.Name Lock_Name
          From Gv$lock      Lk,
               Gv$lock_Type Lt
         Where Lk.Type = Lt.Type
           And lk.inst_id = lt.inst_id
         Group By lk.inst_id,Lk.Sid, Lk.Type, Lt.Name) f,
       (Select Addr,
               inst_id,
               program,
               Sum(Pga_Used_Mem) Pga_Used_Mem,
               Sum(Pga_Alloc_Mem) Pga_Alloc_Mem,
               Sum(Pga_Freeable_Mem) Pga_Freeable_Mem,
               Sum(Pga_Max_Mem) Pga_Max_Mem
          From Gv$process
         Group By Addr,
               inst_id,
               program) g,
       Gv$sort_Usage h
       --Gv$session_Longops Sl
 Where a.Sql_Id = b.Sql_Id
   And b.Sid = c.Sid
   And b.Sid = d.Sid(+)
   And b.Sid = e.Session_Id(+)
   And b.Sid = f.Sid(+)
   And b.Paddr = g.Addr(+)
   And b.Saddr = h.Session_Addr(+)
   --And b.Sid = Sl.Sid(+)
   And b.Status = ACTIVE
   And b.Username In (ogg目标库业务用户);

 

2.从库停掉并删除复制进程
stop replicat repep
dblogin userid goldengate,password goldengate
delete replicat repep

3.配置从库复制进程

>edit params repep
>add replicat repep, exttrail ./dirdat/ep, NODBCHECKPOINT

 

这里先不启动
--repep参数如下

replicat repep
userid goldengate, password AACAAAAAAAAAAAKAPATACEHBIGQGCFZCCDIGAEMCQFFBZHVC ,ENCRYPTKEY DEFAULT
DiscardFile ./dirrpt/repep.dsc, append, Megabytes 200
gettruncates
AllowNoopUpdates
ASSUMETARGETDEFS
DBOPTIONS SUPPRESSTRIGGERS
DBOPTIONS DEFERREFCONST
HANDLECOLLISIONS
MAP hxl.tb_ogg_test ,TARGET hxl.tb_ogg_test;
DDLERROR 10655 IGNORE
DDLERROR 10636 IGNORE

 

4.数据初始化
a.查询主库SCN:select current_scn from v$database,然后修改/home/oracle/impdblink.sh脚本
将FLASHBACK_SCN替换为查出来的值,我这里通过dblink查询
SQL> set numw 20;
SQL> select current_scn from v$database@dblink_dg备库; ##这里是备库的scn,好像也可以连接主库查scn

CURRENT_SCN
--------------------
75738330810


b.执行impdb脚本(/home/oracle/impdblink.sh)
epidb01-> cd /home/oracle
nohup ./impdblink.sh > impdblink.out 2>&1 &

该脚本内容如下:
epidb01-> more impdblink.sh
#! /bin/bash
impdp goldengate/goldengate network_link=dblink_dg主库 FLASHBACK_SCN=2149986 directory=DATA_PUMP_DIR EXCLUDE=STATISTICS cluster=n tables=hxl.tb_ogg_test parallel=40 table_exists_action=replace

dblink_dg主库 这里是连接主库的dblink,若是连接备库的tns会报如下错误

c.从库启动复制进程
GGSCI>start repep aftercsn 2149986

d.启动从库的监听器
lsnrctl start


备注说明:
1.创建dblink
connect goldengate/goldengate
create public database link dblink_dg备库 connect to goldengate identified by goldengate using ‘dg备库TNS‘;
create public database link dblink_dg主库 connect to goldengate identified by goldengate using ‘dg主库TNS‘;
