1.2. OGG 合并REPLICAT进程
1.2.1. 停止extract进程
GGSCI (cndba) 16> stop ext1 Sending STOP request to EXTRACT EXT1 ... Request processed.1.2.2. 检查extract进程的checkpoint信息
GGSCI (cndba) 17> info ext1,showch EXTRACT EXT1 Last Started 2018-06-12 09:26 Status STOPPED Checkpoint Lag 00:00:00 (updated 00:00:09 ago) Log Read Checkpoint Oracle Redo Logs 2018-06-12 09:54:51 Thread 1, Seqno 54, RBA 1670144 SCN 0.1365669 (1365669) 记录下其Write Checkpoint信息中的sequence和RBA值，例如： Write Checkpoint #1 GGS Log Trail Current Checkpoint (current write position): Sequence #: 28 RBA: 1075 Timestamp: 2018-06-12 09:55:06.669489 Extract Trail: ./dirdat/et1.2.3. 检查pump进程的checkpoint信息
GGSCI (cndba) 18> info pump1,showch EXTRACT PUMP1 Last Started 2018-06-12 09:26 Status RUNNING Checkpoint Lag 00:00:00 (updated 00:00:01 ago) Log Read Checkpoint File ./dirdat/et000028 2018-06-12 09:26:30.482435 RBA 1075 若pump进程的Current Checkpoint信息中的sequence和RBA值与ext1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 #: 28 RBA: 1075 Timestamp: 2018-06-12 09:26:30.482435 Extract Trail: ./dirdat/et 同时，记录下其Write Checkpoint信息中的sequence和RBA值。 Write Checkpoint #1 GGS Log Trail Current Checkpoint (current write position): Sequence #: 25 RBA: 1419 Timestamp: 2018-06-12 09:57:38.453158 Extract Trail: ./dirdat/et1.2.4. 检查要合并的replicat进程的checkpoint信息
GGSCI (cndba) 14> info rep1,showch Current Checkpoint (position of last record read in the data source): Sequence #: 25 RBA: 1419 Timestamp: 2018-06-12 09:26:31.096198 Extract Trail: ./dirdat/et GGSCI (cndba) 16> info rep2,showch Current Checkpoint (position of last record read in the data source): Sequence #: 25 RBA: 1419 Timestamp: 2018-06-12 09:26:31.096198 Extract Trail: ./dirdat/et 若replicat进程的Current Checkpoint信息中的sequence和RBA值与pump1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。1.2.5. 停止replicat进程
GGSCI (cndba) 17> stop rep1 Sending STOP request to REPLICAT REP1 ... Request processed. GGSCI (cndba) 19> stop rep2 Sending STOP request to REPLICAT REP2 ... Request processed.1.2.6. 修改rep1 参数
将两个replicat参数配置合并到rep1中，这里把需要单独同步的表注释即可。 GGSCI (cndba) 21> edit params rep1 --tableexclude test.test21.2.7. 启动rep1进程
GGSCI (cndba) 22> start rep1 Sending START request to MANAGER ... REPLICAT REP1 starting 因为这里把两个replicat进程合并到其中一个进程中，没有用新增replicat 方法来做，可以直接启动rep1进程，将rep2 进程删掉。 如果通过新增replicat方法来做的话 ADD REPLICAT rep01,EXTTRAIL ./dirdat/et alter rep01, extseqno 25, extrba 1419 根据第四步中得到的Current checkpoint信息修改新建replicat进程的checkpoint信息，之后新建的replicat进程就会从旧replicat进程停止的位置开始抓取新的信息 然后启动新的replicat进程，删掉两个旧的replicat进程rep1,rep21.2.8. 启动extract进程
GGSCI (cndba) 2> start ext1 Sending START request to MANAGER ... EXTRACT EXT1 starting1.2.9. 删除旧的replicat进程
GGSCI (cndba) 25> dblogin userid ogg,password ogg Successfully logged into database. GGSCI (cndba) 26> delete rep2 Deleted REPLICAT REP2. GGSCI (cndba) 27> info all Program Status Group Lag at Chkpt Time Since Chkpt MANAGER RUNNING REPLICAT RUNNING REP1 00:00:00 00:00:071.2.10. 测试
