OGG，大表拆分

Posted 2020-12-10 dataroot123

OGG进程拆分（单表拆成多个进程）
 
概要：
《OGG进程拆分》介绍了如何将一个入库进程中的多个表拆分到其他进程中。本篇将着重介绍如何使用多个进程同时入库一张表。
适用条件：
1）入库进程只同步一张表，但仍有延时
2）目标段主机CPU、内存压力不大，以便有足够的资源添加新的入库进程
 
本示例将RZG_CXI2中的HX_SB.SB_CWBB_XQYKJZZ_ZCFZB表拆分到RZG_CXI1-RZG_CXI8这8个进程中
1. 创建新添加进程的配置文件

  1，查看 日志序列号和rba (添加进程时注意修改trail文件名，日志序号，rba)
 
   等stop后查看 info RZG_CX2I
 
 
GGSCI (hasthxcxdb01) 33>  info RZG_CX2I
 
REPLICAT   RZG_CX2I  Last Started 2016-06-02 11:39   Status RUNNING

                     2016-05-30 19:43:03.015049  RBA 114276026
 
   2，登录数据库
dblogin Userid ggs,PASSWORD 密码, BLOWFISH, ENCRYPTKEY DEFAULT ##密文部分为OGG用户ggs的密码，也可用明文
 
  3.，添加进程 RZG_CXI
上面已经编辑过8个进程的参数文件，这里添加进程即可
   $ ggsci
   add replicat RZG_CXI1, exttrail ./dirdat/za
   add replicat RZG_CXI2, exttrail ./dirdat/za
   add replicat RZG_CXI3, exttrail ./dirdat/za
   add replicat RZG_CXI4, exttrail ./dirdat/za
   add replicat RZG_CXI5, exttrail ./dirdat/za
   add replicat RZG_CXI6, exttrail ./dirdat/za
   add replicat RZG_CXI7, exttrail ./dirdat/za
   add replicat RZG_CXI8, exttrail ./dirdat/za
 
 
  4， 修改进程检查点
   $ ggsci
    alter replicat RZG_CXI1, extseqno 3124, extrba 114276026
   alter replicat RZG_CXI2, extseqno 3124, extrba 114276026
   alter replicat RZG_CXI3, extseqno 3124, extrba 114276026
   alter replicat RZG_CXI4, extseqno 3124, extrba 114276026
   alter replicat RZG_CXI5, extseqno 3124, extrba 114276026
   alter replicat RZG_CXI6, extseqno 3124, extrba 114276026
   alter replicat RZG_CXI7, extseqno 3124, extrba 114276026
   alter replicat RZG_CXI8, extseqno 3124, extrba 114276026   
 
 
  5，启动新增的8个进程
　start RZG_CXI*
 
 
  6，再次登录数据库，删除原进程
  dblogin Userid ggs,PASSWORD 密码, BLOWFISH, ENCRYPTKEY DEFAULT
   delete RZG_CX2I
