Oracle 19C OGG基础运维-04DML同步常见问题
一：源端添加检查点失败
错误： No checkpoint table specified. Using GLOBALS specification c##ogg.ggschkpt...
GGSCI (cjcos01 as c##ogg@cjcdb/CDB$ROOT) 2> ADD CHECKPOINTTABLE
No checkpoint table specified. Using GLOBALS specification c##ogg.ggschkpt...
ERROR: Catalog name is missing from checkpoint table specification c##ogg.ggschkpt.
解决方案： 用户前指定数据库名
GGSCI (cjcos01 as c##ogg@cjcdb/CDB$ROOT) 2> ADD CHECKPOINTTABLE CDB$ROOT.c##ogg.ggschkpt
二：启动抓取进程ext_01失败
错误： Classic Extract does not support multitenant container databases.
[oracle@cjcos01 ogg]$ tail -f ggserr.log
......
2020-04-09T13:29:22.503+0800 ERROR OGG-06220 Oracle GoldenGate Capture for Oracle, ext_01.prm: Classic Extract does not support multitenant container databases.
2020-04-09T13:29:22.582+0800 ERROR OGG-01668 Oracle GoldenGate Capture for Oracle, ext_01.prm: PROCESS ABENDING.
解决方案： 添加ext_01时指定INTEGRATED
添加抽取进程
---add extract ext_01,tranlog,begin now
---delete extract ext_01
ADD EXTRACT ext_01,INTEGRATED TRANLOG,BEGIN NOW
三：添加pump进程失败
错误： ERROR: Invalid group name (must be at most 8 characters).
GGSCI (cjcos01 as c##ogg@cjcdb/CDB$ROOT) 10> add extract extpump_01,exttrailsource /ogg/dirdat/rt
ERROR: Invalid group name (must be at most 8 characters).
解决方案： 进程名不能大于8个字符，将extpump_01改成pump_01
GGSCI (cjcos01 as c##ogg@cjcdb/CDB$ROOT) 10> add extract pump_01,exttrailsource /ogg/dirdat/rt
四：启动应用进程rep_01失败
错误： Checkpoint table chenpdb.ogg.checkpoint does not exist
2020-04-09T13:49:54.378+0800 ERROR OGG-00446 Oracle GoldenGate Delivery for Oracle, rep_01.prm: Checkpoint table chenpdb.ogg.checkpoint does not exist. Create this table with the ADD CHECKPOINTTABLE command.
解决方案 ：
检查在设置./GLOBALS时表名为chenpdb.ogg.ggschkpt，添加rep_01进程时错写成了chenpdb.ogg.ggschkpt，导致后来启动rep_01失败，删除rep_01重新添加即可
add replicat rep_01,exttrail /ogg/dirdat/mb, CHECKPOINTTABLE chenpdb.ogg.ggschkpt
