1.スプリットとマージOGGポンププロセスとREPLICAT

1.1。OGG分割PUMPプロセスとREPLICAT

1.1.1。extarctプロセスを停止します

GGSCI (cndba) 4> stop ext1

Sending STOP request to EXTRACT EXT1 ...
Request processed.

1.1.2チェックextactプロセスのチェックポイント情報

GGSCI (cndba) 5> info ext1,showch
记录下其Write Checkpoint信息中的sequence和RBA值，如下：
Write Checkpoint #1

  GGS Log Trail

  Current Checkpoint (current write position):
    Sequence #: 29
    RBA: 1351
    Timestamp: 2018-06-12 11:10:24.327370
    Extract Trail: ./dirdat/et

1.1.3。ポンププロセスのチェックポイント情報を確認してください

GGSCI (cndba) 9> info pump1,showch
若pump进程的Current Checkpoint信息中的sequence和RBA值与step 2得到的值相等，则说明goldengate抓取的信息都已被传送到了target服务器上，可继续执行下一步骤。否则，等待并重复运行该命令。
  Current Checkpoint (position of last record read in the data source):
    Sequence #: 29
    RBA: 1351
    Timestamp: 2018-06-12 10:26:36.000000
    Extract Trail: ./dirdat/et
记录其Write Checkpoint信息中的sequence和RBA值，如下：
Write Checkpoint #1

  GGS Log Trail

  Current Checkpoint (current write position):
    Sequence #: 25
    RBA: 1754
    Timestamp: 2018-06-12 11:14:52.629268
    Extract Trail: ./dirdat/et

1.1.4。チェックポイントのプロセス情報確認replicat

GGSCI (cndba) 29> info rep1,showch
  Current Checkpoint (position of last record read in the data source):
    Sequence #: 25
    RBA: 1754
    Timestamp: 2018-06-12 10:26:36.628558
    Extract Trail: ./dirdat/et
若replicat进程的Current Checkpoint信息中的sequence和RBA值与step 3中得到的Write Checkpoint信息相等，则说明goldengate抓取的信息都已被apply到target 数据库，可继续执行下一步骤。否则，等待并重复运行该命令。

1.1.5。ポンププロセスとプロセスreplicatを停止

--源端操作
GGSCI (cndba) 10> stop pump1

Sending STOP request to EXTRACT PUMP1 ...
Request processed.
--目标端操作
GGSCI (cndba) 30> stop rep1

Sending STOP request to REPLICAT REP1 ...
Request processed.

1.1.6。二つの新しいポンプ・プロセスを作成します。

add extract pump01,exttrailsource ./dirdat/et,begin now
add rmttrail ./dirdat/p1,extract pump01
add extract pump02,exttrailsource ./dirdat/et,begin now
add rmttrail ./dirdat/p2,extract pump02

1.1.7。ポンププロセスの設定ファイルを追加します

这两个新的参数文件与原有的参数文件的主要区别是将其中的复制表按负载均分为了两部分，分别放在单独的参数文件中。
GGSCI (cndba) 15> edit params pump01
GGSCI (cndba) 18> view params pump01

EXTRACT pump01
RMTHOST 192.168.1.86, MGRPORT 7809

PASSTHRU
DYNAMICRESOLUTION
TABLE test.test;

GGSCI (cndba) 16> edit params pump02
GGSCI (cndba) 19> view params pump02

EXTRACT pump02
RMTHOST 192.168.1.86, MGRPORT 7809
RMTTRAIL ./dirdat/p2
PASSTHRU
DYNAMICRESOLUTION
TABLE test.test2;

1.1.8。チェックポイントのプロセスを読んで新しいポンプ情報を変更します。

根据step 3中得到的read checkpoint信息修改新建pump进程的checkpoint信息，让其从旧pump进程停止的位置开始抓取新的信息
GGSCI (cndba) 26> ALTER EXTRACT pump01, EXTSEQNO 25, EXTRBA 1754
EXTRACT altered.

GGSCI (cndba) 27> ALTER EXTRACT pump02, EXTSEQNO 25, EXTRBA 1754

1.1.9。二つの新しいreplicatプロセスを作成します。

GGSCI (cndba) 31> add replicat rep01, exttrail ./dirdat/p1, checkpointtable ogg.checkpoint
REPLICAT added.

GGSCI (cndba) 32> add replicat rep02, exttrail ./dirdat/p2, checkpointtable ogg.checkpoint
REPLICAT added.
