Oracle GoldenGate学习之--GoldenGate的监控
1、使用GGSCI命令监控
（1）进入GoldenGate安装目录，运行GGSCI，然后使用info all查看整体的运行状况
GGSCI (aix212) 1> info all Program Status Group Lag at Chkpt Time Since Chkpt MANAGER RUNNING EXTRACT RUNNING EORA_1 00:00:00 00:00:03 EXTRACT RUNNING PORA_1 00:00:00 00:00:00 GGSCI (aix211) 1> info all Program Status Group Lag at Chkpt Time Since Chkpt MANAGER RUNNING REPLICAT RUNNING RORA_1 00:00:00 00:00:09
Group表示进程的名称（MGR进程不显示名字）；
Lag表示进程的延时；Status表示进程的状态，有4种状态。
STARTING 表示正在启动过程中。
RUNNING 表示进程正常运行。
STOPPED 表示进程被正常关闭。
ABENDED 表示进程非正常关闭，需要进一步调查原因。
正常情况下，所有进程的状态应该为RUNNING，且Lag应该在一个合理的范围内。
（2）使用view params <进程名> 可以查看进程的参数设置，该命令支持通配符*
源端： GGSCI (aix212) 4> view param mgr dynamicportlist 7800-8000 autorestart extract *,waitminutes 2,resetminutes 5 GGSCI (aix212) 7> view param eini_1 EXTRACT EINI_1 SETENV (NLS_LANG=AMERICAN_AMERICA.ZHS16GBK) USERID ogg,PASSWORD ogg RMTHOST 192.168.8.211,MGRPORT 7809 RMTTASK REPLICAT, GROUP RINI_1 TABLE scott.EMP_OGG; GGSCI (aix212) 5> view param eora_1 EXTRACT EORA_1 SETENV (NLS_LANG=AMERICAN_AMERICA.ZHS16GBK) USERID ogg,PASSWORD ogg EXTTRAIL ./dirdat/aa TABLE scott.emp_ogg; GGSCI (aix212) 6> view param pora_1 EXTRACT PORA_1 SETENV (NLS_LANG=AMERICAN_AMERICA.ZHS16GBK) PASSTHRU RMTHOST 192.168.8.211,MGRPORT 7809 RMTTRAIL ./dirdat/pa TABLE scott.emp_ogg; 目标端： GGSCI (aix211) 4> view param mgr port 7809 dynamicportlist 7800-8000 autorestart extract *,waitminutes 2,resetminutes 5 GGSCI (aix211) 3> view param rini_1 REPLICAT RINI_1 SETENV (NLS_LANG=AMERICAN_AMERICA.ZHS16GBK) ASSUMETARGETDEFS USERID ogg,PASSWORD ogg DISCARDFILE ./dirrpt/RINIaa.dsc,PURGE MAP scott.emp_ogg, TARGET scott.emp_ogg; GGSCI (aix211) 2> view param rora_1 REPLICAT RORA_1 SETENV (NLS_LANG=AMERICAN_AMERICA.ZHS16GBK) USERID ogg,PASSWORD ogg HANDLECOLLISIONS ASSUMETARGETDEFS DISCARDFILE ./dirrpt/RORA_aa.DSC,PURGE MAP scott.oem_ogg, TARGET scott.emp_ogg;
（3）使用info <进程名称> 命令可以查看进程信息，可以查看到的信息包括进程状态、checkpoint信息、延时等
GGSCI (aix212) 8> info eora_1 EXTRACT EORA_1 Last Started 2014-09-25 16:09 Status RUNNING Checkpoint Lag 00:00:00 (updated 00:00:04 ago) Log Read Checkpoint Oracle Redo Logs 2014-09-25 17:00:16 Seqno 5, RBA 21645824 SCN 0.658565 (658565) GGSCI (aix212) 9> info pora_1 EXTRACT PORA_1 Last Started 2014-09-25 16:09 Status RUNNING Checkpoint Lag 00:00:00 (updated 00:00:05 ago) Log Read Checkpoint File ./dirdat/pa000000 First Record RBA 0 GGSCI (aix211) 5> info rora_1 REPLICAT RORA_1 Last Started 2014-09-25 16:25 Status RUNNING Checkpoint Lag 00:00:00 (updated 00:00:04 ago) Log Read Checkpoint File ./dirdat/pa000000 First Record RBA 0
（4）还可以使用info <进程名称> detail 命令查看更详细的信息，包括所使用的trail文件、参数文件、报告文件、警告日志的位置等
GGSCI (aix212) 10> info eora_1 detail EXTRACT EORA_1 Last Started 2014-09-25 16:09 Status RUNNING Checkpoint Lag 00:00:00 (updated 00:00:02 ago) Log Read Checkpoint Oracle Redo Logs 2014-09-25 17:01:58 Seqno 5, RBA 21770240 SCN 0.658666 (658666) Target Extract Trails: Remote Trail Name Seqno RBA Max MB ./dirdat/aa 2 2354 5 Extract Source Begin End /u01/app/oracle/oradata/orcl/redo01.log 2014-09-25 16:07 2014-09-25 17:01 /u01/app/oracle/oradata/orcl/redo01.log 2014-09-23 20:34 2014-09-25 16:08 /u01/app/oracle/oradata/orcl/redo03.log 2014-09-23 15:17 2014-09-23 20:35 Not Available * Initialized * 2014-09-23 15:17 Current directory /ogg Report file /ogg/dirrpt/EORA_1.rpt Parameter file /ogg/dirprm/eora_1.prm Checkpoint file /ogg/dirchk/EORA_1.cpe Process file /ogg/dirpcs/EORA_1.pce Stdout file /ogg/dirout/EORA_1.out Error log /ogg/ggserr.log GGSCI (aix211) 6> info rora_1 detail REPLICAT RORA_1 Last Started 2014-09-25 16:25 Status RUNNING Checkpoint Lag 00:00:00 (updated 00:00:04 ago) Log Read Checkpoint File ./dirdat/pa000000 First Record RBA 0 Extract Source Begin End ./dirdat/pa000000 * Initialized * First Record ./dirdat/pa000000 * Initialized * First Record Current directory /ogg Report file /ogg/dirrpt/RORA_1.rpt Parameter file /ogg/dirprm/rora_1.prm Checkpoint file /ogg/dirchk/RORA_1.cpr Checkpoint table ogg.checkpoint Process file /ogg/dirpcs/RORA_1.pcr Stdout file /ogg/dirout/RORA_1.out Error log /ogg/ggserr.log
（5）使用info <进程名称> showch 命令可以查看到详细的关于checkpoint的信息，用于查看GoldenGate进程处理过的事务记录
GGSCI (aix212) 11> info eora_1 showch EXTRACT EORA_1 Last Started 2014-09-25 16:09 Status RUNNING Checkpoint Lag 00:00:00 (updated 00:00:03 ago) Log Read Checkpoint Oracle Redo Logs 2014-09-25 17:04:50 Seqno 5, RBA 21797888 SCN 0.658739 (658739) Current Checkpoint Detail: Read Checkpoint #1 Oracle Redo Log Startup Checkpoint (starting position in the data source): Thread #: 1 Sequence #: 5 RBA: 19244560 Timestamp: 2014-09-25 16:07:15.000000 SCN: 0.656759 (656759) Redo File: /u01/app/oracle/oradata/orcl/redo01.log Recovery Checkpoint (position of oldest unprocessed transaction in the data source): Thread #: 1 Sequence #: 5 RBA: 21795856 Timestamp: 2014-09-25 17:04:43.000000 SCN: 0.658736 (658736) Redo File: /u01/app/oracle/oradata/orcl/redo01.log Current Checkpoint (position of last record read in the data source): Thread #: 1 Sequence #: 5 RBA: 21797888 Timestamp: 2014-09-25 17:04:50.000000 SCN: 0.658739 (658739) Redo File: /u01/app/oracle/oradata/orcl/redo01.log BR Previous Recovery Checkpoint: Thread #: 0 Sequence #: 0 RBA: 0 Timestamp: 2014-09-23 15:22:40.485502 SCN: Not available Redo File: BR Begin Recovery Checkpoint: Thread #: 1 Sequence #: 4 RBA: 10054144 Timestamp: 2014-09-23 19:22:47.000000 SCN: 0.629912 (629912) Redo File: BR End Recovery Checkpoint: Thread #: 1 Sequence #: 4 RBA: 10054144 Timestamp: 2014-09-23 19:22:47.000000 SCN: 0.629912 (629912) Redo File: Write Checkpoint #1 GGS Log Trail Current Checkpoint (current write position): Sequence #: 2 RBA: 2354 Timestamp: 2014-09-25 17:04:54.617925 Extract Trail: ./dirdat/aa CSN state information: CRC: B9-8B-16-BD Latest CSN: 658581 Latest TXN: 3.47.317 Latest CSN of finished TXNs: 658581 Completed TXNs: 3.47.317 Header: Version = 2 Record Source = A Type = 10 # Input Checkpoints = 1 # Output Checkpoints = 1 File Information: Block Size = 2048 Max Blocks = 100 Record Length = 2048 Current Offset = 0 Configuration: Data Source = 3 Transaction Integrity = 1 Task Type = 0 Status: Start Time = 2014-09-25 16:09:02 Last Update Time = 2014-09-25 17:04:54 Stop Status = A Last Result = 400
其中比较重要的是Extract进程的recovery checkpoint，它表示源数据中最早的未被处理的事务；通过recovery checkpoint可以查看到该事务的redo log位于哪个日志文件以及该日志文件的序列号。
所有序列号比它大的日志文件，均需要保留。
（6）lag <进程名称> 可以查看详细的延时信息
GGSCI (aix212) 12> lag eora_1 Sending GETLAG request to EXTRACT EORA_1 ... Last record lag: 2 seconds. At EOF, no more records to process.
（7）stats可以查看进程处理的记录数：
该报告会详细地列出处理的类型和记录数，例如：
stats <进程名称>,<时间频度>,table <owner name>.<table name>
GGSCI (aix212) 13> stats eora_1, total Sending STATS request to EXTRACT EORA_1 ... Start of Statistics at 2014-09-25 17:08:54. Output to ./dirdat/aa: Extracting from SCOTT.EMP_OGG to SCOTT.EMP_OGG: *** Total statistics since 2014-09-25 16:11:23 *** Total inserts 3.00 Total updates 0.00 Total deletes 6.00 Total discards 0.00 Total operations 9.00 End of Statistics.
列出自进程启动以来处理的所有记录数，如图11-8所示。
GGSCI (aix212) 15> stats eora_1,daily, table scott.emp_ogg Sending STATS request to EXTRACT EORA_1 ... Start of Statistics at 2014-09-25 17:11:16. Output to ./dirdat/aa: Extracting from SCOTT.EMP_OGG to SCOTT.EMP_OGG: *** Daily statistics since 2014-09-25 16:11:23 *** Total inserts 3.00 Total updates 0.00 Total deletes 6.00 Total discards 0.00 Total operations 9.00 End of Statistics.
列出当天以来处理的有关scott.emp_ogg表的所有记录数。
（8）view report <进程名称> 可以查看运行报告

案例分析2：
源端初始化进程（eini_1)和目标端初始化进程（rini_1)
目标端初始化进程rini_1：
GGSCI (aix211) 13> info rini_1 REPLICAT RINI_1 Initialized 2014-09-23 15:40 Status STOPPED Checkpoint Lag 00:00:00 (updated 48:46:37 ago) Log Read Checkpoint Not Available Task SPECIALRUN
源端初始化进程eini_1：
GGSCI (aix212) 21> info eini_1 EXTRACT EINI_1 Last Started 2014-09-25 16:09 Status STOPPED Checkpoint Lag Not Available Log Read Checkpoint Table SCOTT.EMP_OGG 2014-09-25 16:09:35 Record 14 Task SOURCEISTABLE
启动源端初始化进程：
GGSCI (aix212) 22> start eini_1 Sending START request to MANAGER ... EXTRACT EINI_1 starting GGSCI (aix212) 23> info eini_1 EXTRACT EINI_1 Last Started 2014-09-25 16:09 Status RUNNING Checkpoint Lag Not Available Log Read Checkpoint Table SCOTT.EMP_OGG 2014-09-25 16:09:35 Record 14 Task SOURCEISTAB
进程启动后，目标端初始化进程自动启动！
GGSCI (aix211) 14> info rini_1 REPLICAT RINI_1 Initialized 2014-09-23 15:40 Status RUNNING Checkpoint Lag 00:00:00 (updated 48:47:03 ago) Log Read Checkpoint Not Available Task SPECIALRUN
