前言:

本文档主要描述通过Oracle Grid Infrastructure Agents (XAG)基于Oracle RAC实现GoldenGate(OGG)软件高可用的实施操作

环境信息：

源端OGG高可用配置:

            1 配置vip资源:

--添加vip资源，这里使用集群新建的network 2网络，可以使用默认的network 1，同网段即可
#network is the network number that you want to use. 
#ip is the IP address provided by your system administrator for the new Application VIP. This IP address must be in the same subnet as determined above.
#gg_vip_source is the name of the application VIP that you will create.
​
/u01/app/11.2.0/grid/bin/appvipcfg create -network=2 \-ip=192.168.1.88 \-vipname=gg_vip_source \-user=root--root授权Oracle用户有启动vip的权限
/u01/app/11.2.0/grid/bin/crsctl setperm resource gg_vip_source -u user:oracle:r-x
--Oracle用户启动资源
/u01/app/11.2.0/grid/bin/crsctl start resource gg_vip_source
--验证资源
[oracle@rac1 ~]$ /u01/app/11.2.0/grid/bin/crsctl status resource gg_vip_source
NAME=gg_vip_source
TYPE=app.appvip_net2.type
TARGET=ONLINE
STATE=ONLINE on rac2

          2 配置ACFS资源:

--配置ACFS，在节点一操作即可
--添加vol卷
su  -grid
ASMCMD> volcreate -G DATA -s 5G acfsvol
--查看acfs生成的卷组
su - grid 
ASMCMD> volinfo -G DATA acfsvol
Diskgroup Name: DATA
​Volume Name: ACFSVOLVolume Device: /dev/asm/acfsvol-119State: ENABLEDSize (MB): 5120Resize Unit (MB): 32Redundancy: UNPROTStripe Columns: 4Stripe Width (K): 128Usage: Mountpath: 
--挂载/ogg 文件系统
--确认asm下面生成acfs卷组
# ls /dev/asm
--创建挂载目录
su - root 
mkdir /ogg
--格式划acfs 
su - root 
# /sbin/mkfs -t acfs /dev/asm/acfsvol-119
--加入集群管理
su - root
/u01/app/11.2.0/grid/bin/srvctl add filesystem -d /dev/asm/acfsvol-119 -g 'DATA' -v ACFSVOL -m /ogg -u oracle
--挂载
/u01/app/11.2.0/grid/bin/srvctl start filesystem -d /dev/asm/acfsvol-119
--查看是否online以及mount
su - grid
crsctl stat res -t |grep -i acfs
ora.data.acfsvol.acfs
ora.registry.acfs
df -h
--如果没有online,再手动mount
su - root 
# mount.acfs -o all
--授予目录权限
su - root 
# chown oracle.oinstall /ogg

        3 安装ogg软件：

--安装ogg软件,要安装在acfs所在的目录/ogg里面
cd fbo_ggs_Linux_x64_shiphome/
cd Disk1/
./runInstaller

        4 ogg开启ddl支持:

sqlplus / as sysdba
@marker_setup.sql
@ddl_setup.sql
@role_setup.sql
GRANT GGS_GGSUSER_ROLE TO ogg_owner;
@ddl_enable.sql
@?/rdbms/admin/dbmspool.sql
@ddl_pin ogg_owner

        5 配置MGR进程:

--需要注意配置的参数是autostart，因为高可用是依靠mgr去自动启动进程的
GGSCI (rac1) 3> edit params mgr
port 7809
DYNAMICPORTLIST 7940-8100
AUTOSTART ER *
AUTORESTART ER *,RETRIES 10, WAITMINUTES 1, RESETMINUTES 60
PURGEOLDEXTRACTS /ogg/dirdat/*,USECHECKPOINTS,MINKEEPDAYS 5
LAGREPORTHOURS 1
LAGINFOMINUTES 30
LAGCRITICALMINUTES 45
--启动mgr进程
GGSCI (rac1) 5> start mgr

        6 源端添加表级附加日志:

--连接数据库
GGSCI>dblogin userid ogg password ogg
--添加表级附加日志    
GGSCI>add trandata test.* 
--显示日志添加情况                 
GGSCI>info trandata test.*   

        7 配置EXTRACT进程:

--添加extract进程
add extract E_BSS_1 tranlog,begin now,threads 2
add exttrail ./dirdat/es,extract E_BSS_1,megabytes 1000
--需要注意的是要通过tns去连接数据库，而不是ORACLE_SID方式，并且连接的tns需要可以访问到全部节点，最好连scan_ip
--配置ogg连接数据库的tns
ORCL =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = rac-scan)(PORT = 1521))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = orcl)))
--配置extract进程
GGSCI (rac1) 3> edit params e_bss_1
extract E_BSS_1
SETENV (ORACLE_HOME = "/u01/app/oracle/product/11.2.0/db_1")

        8 配置PUMP进程:

--添加投递进程
add extract P_BSR_1,exttrailsource ./dirdat/es
add RMTTRAIL ./dirdat/rs,ext P_BSR_1,megabytes 1000
--需要注意的是这里远程的IP是目标端的VIP，这样才能在failover之后，依然可以正常投递

--agctl添加高可用source_ogg实例,oracle用户执行以及管理

--注意这里的database也可以不用设置，这里的设置主要是强关联database，这样当节点的database关闭会触发ogg failover

agctl stop goldengate target_ogg
--手动切换source_ogg实例到去其他节点，用oracle用户执行
agctl relocate  goldengate target_ogg --node rac2

测试OGG高可用配置:

        1 源端OGG节点主机重启:

--在源端开启会话，模拟表操作
declarev_count number(10):=0;
beginfor i in 1..1000000 loopinsert into test.test select * from dba_objects where rownum<4;delete from test.test where rownum<2;update test.test set owner='aaa'where rownum<2;v_count:=v_count+1;if v_count>=1 THENcommit;v_count:=0;end if;end loop;commit;
end;
/ 
​
--当前源端ogg所在节点主机rac1
[oracle@rac1 ~]$ agctl  status goldengate source_ogg
Goldengate  instance 'source_ogg' is running on rac1
--重启主机rac1
--ogg实例服务会自动转移到节点二rac2
[oracle@rac2 ogg]$ agctl  status goldengate source_ogg
Goldengate  instance 'source_ogg' is running on rac2
[oracle@rac2 ogg]$ ./ggsci
