OGG目的端的checkpoint table被drop的修复方法
参考自：OGG Replicat Failed Due To Check_point Table beingTruncated (文档 ID 1319832.1)
1.首先，start repfull报错：
GGSCI (localhost.localdomain) 8> view report repfull

able.

2.于是，就建立上goldengate.ckptfull 这个表：
GGSCI (localhost.localdomain) 9> dblogin userid goldengate, password xxx
Successfully logged into database.
GGSCI (localhost.localdomain) 10> ADD CHECKPOINTTABLE goldengate.ckptfull
Successfully created checkpoint table goldengate.ckptfull.
3.此时，start repfull报错：

2015-06-11 09:03:03 ERROR OGG-01668 PROCESS ABENDING.
4.得到repfull的读检查点信息：
GGSCI (localhost.localdomain) 16> info repfull
REPLICAT REPFULL Last Started 2015-06-11 08:30 Status ABENDED
Checkpoint Lag 00:00:00 (updated 00:33:01 ago)
Log Read Checkpoint File /u02/ggs/dirdat/td000001 ---->1
First Record RBA 1192 ---->1192
5.修改检查点（其实不叫修改，就是重复一下而已）
GGSCI (localhost.localdomain) 17> alter replicat repfull, extseqno 1, extrba 1192
REPLICAT altered.
GGSCI (localhost.localdomain) 18> info repfull
REPLICAT REPFULL Initialized 2015-06-11 09:05 Status STOPPED
Checkpoint Lag 00:00:00 (updated 00:00:04 ago)
Log Read Checkpoint File /u02/ggs/dirdat/td000001
First Record RBA 1192
6.启动repfull进程，
GGSCI (localhost.localdomain) 19> start repfull
Sending START request to MANAGER ...
REPLICAT REPFULL starting
注意，此时goldengate.ckptfull表里边才被插入一条记录。
7.检查状态：
GGSCI (localhost.localdomain) 41> info all
Program Status Group Lag at Chkpt Time Since Chkpt
MANAGER RUNNING
REPLICAT RUNNING REPFULL 00:00:00 00:00:01
