OGG initail load 使用文件传输初始化
一、mgr 进程配置(源端和目标端使用相同的配置)
GGSCI (oradb) 1> view params mgr
PORT 7809
二、源端批量抽取进程配置
GGSCI (oradb) 4> edit params extftor
SOURCEISTABLE
userid ggs,password ggs
rmthost 192.168.222.154,mgrport 7809
rmtfile ./dirdat/pp
--rmtfile ./dirdat/pp,maxfiles 5000,megabytes 500
table lixia.t10;
三、目标端批量复制进程配置
GGSCI (fmsserver) 3> edit params repftor
SPECIALRUN
END RUNTIME
userid ggs,password ggs
extfile ./dirdat/pp
ASSUMETARGETDEFS
map lixia.t10,target lixia.t10;
四、源端启动MGR
GGSCI (oradb) 4> start mgr
Manager started.
五、目标端启动MGR
GGSCI (fmsserver) 6> start mgr
Manager started.
六、在源端使用操作系统命令发起 extract(注意：此种 extract,ggsci的info all是看不到的)
[oracle@oradb ~]$ cd /home/oracle
[oracle@oradb ~]$ /app/gg2/extract PARAMFILE /app/gg2/dirprm/extftor.prm REPORTFILE /app/gg2/dirrpt/EXTFTOR.rpt
--源端批量抽取进程执行失败，而且OGG的错误日志没有任何输出，这个时候查看操作系统 /var/log/messages日志，看你到如下错误信息
[root@oradb ~]# tail -100 /var/log/messages

function from line 2862 in cm_cachedir_add() failed with reason 'The directory /home/oracle/dirtmp to

处理：切换到 /app/gg2 目录再执行命令
[oracle@oradb dirrpt]$ cd /app/gg2/
[oracle@oradb gg2]$ pwd
/app/gg2
[oracle@oradb gg2]$ /app/gg2/extract PARAMFILE /app/gg2/dirprm/extftor.prm REPORTFILE /app/gg2/dirrpt/EXTFTOR.rpt
七、在目标端的 /app/gg2/dirdat 目录可以看如下文件
[oracle@fmsserver dirdat]$ ls -lrt pp*|wc -l
1
[oracle@fmsserver dirdat]$ ls -lrth pp*
-rw-r-----. 1 oracle oinstall 29M Nov 22 11:55 pp000000
[oracle@fmsserver dirdat]$ pwd
/app/gg2/dirdat
八、等待 extrac 完成，可以从/app/gg2/dirrpt/EXTFTOR.rpt 判断
[oracle@oradb dirrpt]$ cd /app/gg2/dirrpt
[oracle@oradb dirrpt]$ cat EXTFTOR.rpt

九、在目标端使用操作系统命令启动批量复制进程
[oracle@fmsserver gg2]$ /app/gg2/replicat paramfile /app/gg2/dirprm/repftor.prm reportfile /app/gg2/dirrpt/REPFTOR.rpt
十、等待 replicat 完成，可以从 /app/gg2/dirrpt/REPFTOR.rpt 中判断
[oracle@fmsserver dirrpt]$ more REPFTOR.rpt
。。。。。 省略 N行 。。。。
