数据收集应用比较慢，如果这个进程只有一个大表，我们可以进行开range，以下开4个并发
步骤如下：

1，编辑参数文件，复制3份

wei:wei> vi reweicob.prm

replicat reweicob
setenv (NLS_LANG = AMERICAN_AMERICA.AL32UTF8)
setenv (ORACLE_HOME=/dba/oracle/product/11.2.0.3.0)
setenv (ORACLE_SID=wei)
userid goldengate, password *******
REPORTCOUNT EVERY 30 MINUTES,RATE
REPORT AT 01:59
reportrollover at 02:00
discardrollover on friday
--handlecollisions
reperror default,abend
discardfile ./dirrpt/reweicosbi.dsc,append, megabytes 1000 GOLDENGATE.CHECKPOINT_LGDNEW
复制4份
wei:cos > ls
 reweicob_2.prm  reweicob_3.prm  reweicob_4.prm  reweicob.prm 
2，对复制的文件进行编辑修改
 reweicob_3.prm  reweicob_4.prm  一样修改，安红色字体修改

wei:cos > vi reweicob_2.prm

replicat reweicob_2
setenv (NLS_LANG = AMERICAN_AMERICA.AL32UTF8)
setenv (ORACLE_HOME=/dba/oracle/product/11.2.0.3.0)
setenv (ORACLE_SID=cos)
userid goldengate, password *********
REPORTCOUNT EVERY 30 MINUTES,RATE
REPORT AT 01:59
reportrollover at 02:00
discardrollover on friday
--handlecollisions
reperror default,abend
discardfile ./dirrpt/reweicosbi_2.dsc,append, megabytes 1000 GOLDENGATE.CHECKPOINT_LGDNEW

map wei_COS.COMPLAIN,  TARGET wei_COS.COMPLAIN, KEYCOLS(JOB_ID),FILTER (@RANGE(2,4,JOB_ID));---job_id 代表主键有几个需要写几个
stop 进程

GGSCI (wei) 8> stop reweicob

文件主要修改内容如下：
map wei_table.wei,  TARGET wei_table.wei, KEYCOLS(JOB_ID),FILTER (@RANGE(1,4,JOB_ID));
map wei_table.wei,  TARGET wei_table.wei, KEYCOLS(JOB_ID),FILTER (@RANGE(2,4,JOB_ID));
map wei_table.wei,  TARGET wei_table.wei, KEYCOLS(JOB_ID),FILTER (@RANGE(3,4,JOB_ID));
map wei_table.wei,  TARGET wei_table.wei, KEYCOLS(JOB_ID),FILTER (@RANGE(4,4,JOB_ID));

3，查看配置和检查点 --可以看到checkpoint table

GGSCI (wei) 59> info reweicob,showch

4,增加进程

GGSCI (wei) 11> dblogin userid goldengate, password test3213_a
GGSCI (wei) 12>ADD REPLICAT reweicob_2 EXTTRAIL ./dirdat/ec, CHECKPOINTTABLE GOLDENGATE.CHECKPOINT_WEI ;
GGSCI (wei) 12>ADD REPLICAT reweicob_3 EXTTRAIL ./dirdat/ec, CHECKPOINTTABLE GOLDENGATE.CHECKPOINT_WEI ;
GGSCI (wei) 12>ADD REPLICAT reweicob_4 EXTTRAIL ./dirdat/ec, CHECKPOINTTABLE GOLDENGATE.CHECKPOINT_WEI ;

5，修改启动sequence

GGSCI (wei) 8> info reweicob

EXTRACT    reweicob Last Started 2014-06-28 23:28   Status stop
Checkpoint Lag       00:03:44 (updated 00:00:00 ago)
Log Read Checkpoint  Oracle Redo Logs
                     2014-07-15 17:27:15  Thread 1, Seqno 000301, RBA 46033645

 GGSCI (wei) 12> alter reweicob_2 , extseqno 301, extrba 46033645
GGSCI (wei) 12> alter reweicob_3 , extseqno 301, extrba 46033645
GGSCI (wei) 12> alter reweicob_4, extseqno 301, extrba 46033645

6,启动修改的后各进程
  GGSCI (wei) 12> start reweicob*

以上就完成了
