背景:
工作任务OGG新增下发表,根据系统架构,数据下发流程为:系统A --> 系统B --> 系统C
系统A:在与系统B相关的抽取进程(EXTSJXF)的参数文件中新增相关表,在与系统B相关的投递进程(DPDJZSJ1)的参数文件中新增相关表。
系统B:复制进程(REPDJZ2)的参数文件中新增相关表,进行应用,在与系统C相关的抽取进程(EXTJHXT1)的参数文件中新增下发表,同理,投递进程(DPJHSJ1)亦需要在进程参数文件中新增表
系统C:复制进程(REPJHXT1)参数文件新增相关表
下发表说明:业务问题,系统A用户QAS的数据将导入到系统B的用户QAS_TEST下(remap table),即
系统A:QAS.T_LOG_TICKET_PROVINCE、QAS.T_LOG_TICKET_TASK_PROVINCE
系统B:QAS_TEST.T_LOG_TICKET_PROVINCE 、QAS_TEST.T_LOG_TICKET_TASK_PROVINCE
通过datapump初始化,总体工作流程如下:
一、工作步骤:
1、 系统A --> 系统B
(1)系统A抽取进程EXTSJXF修改参数文件
GGSCI (A)1> stop EXTSJXF --停止进程进行参数文件修改 GGSCI (A)2> edit param EXTSJXF ---编辑参数文件新增如下 --20170808 add TABLE QAS.* ; --登录数据库goldengate用户,打开表级附加日志 GGSCI (A) 3>dblogin userid goldengate password goldengate; GGSCI (A) 4>ADD TRANDATA QAS.T_LOG_TICKET_PROVINCE GGSCI (A) 5>ADD TRANDATA QAS.T_LOG_TICKET_TASK_PROVINCE GGSCI (A) 6> start EXTSJXF
(2)系统A投递进程DPDJZSJ1修改参数文件
GGSCI (A) 7> stop DPDJZSJ1 GGSCI (A) 8> edit param DPDJZSJ1 --20170808 add TABLE QAS.* ;
(3)停止系统B复制进程REPDJZ2
GGSCI (B) 1> stop REPDJZ2
(4)系统A基于SCN号抽取数据
SQL> select sum(BYTES/1024/1024) MB from dba_segments where owner =‘QAS‘ and SEGMENT_NAME=‘T_LOG_TICKET_PROVINCE‘; MB ---------- 560.0625 SQL> select sum(BYTES/1024/1024) MB from dba_segments where owner =‘QAS‘ and SEGMENT_NAME=‘T_LOG_TICKET_TASK_PROVINCE‘; MB ---------- 1816.0625
SQL> create directory OGG_EXPDP as ‘/data4/ogg_expdp‘;

GGSCI (B) 19> ADD TRANDATA QAS_GZDS.T_LOG_TICKET_TASK_PROVINCE Logging of supplemental redo data enabled for table QAS_GZDS.T_LOG_TICKET_TASK_PROVINCE. GGSCI (B) 20> info TRANDATA QAS_GZDS.T_LOG_TICKET_TASK_PROVINCE Logging of supplemental redo log data is enabled for table QAS_GZDS.T_LOG_TICKET_TASK_PROVINCE.

vi expdp_sj2_sj1_2tb_20170808.par USERID=‘/ as sysdba‘ DIRECTORY=IMPDP LOGFILE=expdp_sj2_sj1_2tb_20170808.log FLASHBACK_SCN=15389350836731 DUMPFILE=expdp_sj2_sj1_2tb_20170808.dmp tables=(QAS_GZDS.T_LOG_TICKET_PROVINCE, QAS_GZDS.T_LOG_TICKET_TASK_PROVINCE) --后台执行脚本 nohup expdp parfile=expdp_sj2_sj1_2tb_20170808.par > expdp_sj2_sj1_2tb_20170808.par.out &
(5)scp将dmp文件从系统B传至系统C

(6)系统C导入数据
vi impdp_sj2_sj1_2tb_20170808.par USERID=‘/ as sysdba‘ DIRECTORY=IMPDP LOGFILE=impdp_sj2_sj1_2tb_20170808.log DUMPFILE=expdp_sj2_sj1_2tb_20170808.dmp TABLE_EXISTS_ACTION=replace --后台执行脚本 nohup impdp parfile=impdp_sj2_sj1_2tb_20170808.par > impdp_sj2_sj1_2tb_20170808.par.out &
(7)系统C复制进程REPDJZ2参数文件修改
--20170808 add 2tbs MAP QAS_GZDS.T_LOG_TICKET_PROVINCE ,TARGET QAS_GZDS.T_LOG_TICKET_PROVINCE ,FILTER(@GETENV("TRANSACTION","CSN")>15389350836731); MAP QAS_GZDS.T_LOG_TICKET_TASK_PROVINCE ,TARGET QAS_GZDS.T_LOG_TICKET_TASK_PROVINCE ,FILTER(@GETENV("TRANSACTION","CSN")>15389350836731);
--系统B基于SCN号导出,系统C基于CSN号开启复制进程应用
(8)开启系统B的投递进程DPJHSJ1
GGSCI (B) 11> sart DPJHSJ1
(9)开启系统C的应用进程REPJHXT1
GGSCI (C) 3> start REPJHXT1
(10)数据对比
GGSCI (B) 11> stats DPJHSJ1,daily GGSCI (C) 4> stats REPJHXT1,daily
--系统B: SQL> select count(1) from QAS_GZDS.T_LOG_TICKET_TASK_PROVINCE; COUNT(1) ---------- 16919333 SQL> select count(1) from QAS_GZDS.T_LOG_TICKET_PROVINCE; COUNT(1) ---------- 4618927 ---系统C: SQL> select count(1) from QAS_GZDS.T_LOG_TICKET_TASK_PROVINCE; COUNT(1) ---------- 16919333 SQL> select count(1) from QAS_GZDS.T_LOG_TICKET_PROVINCE; COUNT(1) ---------- 4618927
三、其他说明:
1、打开表级附加日志时无唯一索引处理
系统A数据在导入系统B时索引已存在,由于系统B需抽取此部分数据投递至系统C,在附加表级日志时最好有唯一索引作为唯一key以保障数据的唯一性。所以在系统B中重命名原先的索引。此处解决方案考虑结合了系统的业务情况。无唯一索引附加表级日志出现以下告警:
GGSCI (B) 10> ADD TRANDATA QAS_TEST.T_LOG_TICKET_PROVINCE 2017-08-08 15:21:19 WARNING OGG-00869 No unique key is defined for table ‘T_LOG_TICKET_PROVINCE‘. All viable columns will be used to represent the key, but may not guarantee uniqueness. KEYCOLS may be used to define the key. Logging of supplemental redo data enabled for table QAS_TEST.T_LOG_TICKET_PROVINCE.
(1) 在dmp文件中提取出sql语句
vi impdp_djz_sj2_oas_sql_2017080.par USERID =‘/ as sysdba‘ DIRECTORY = IMPDP DUMPFILE = expdp_djz_shiju2_oas_20170808.dmp LOGFILE=impdp_djz_sj2_oas_sql_20170808.log SQLFILE=impdp_djz_sj2_oas_sql_20170808.sql INCLUDE=INDEX,CONSTRAINT nohup impdp parfile=impdp_djz_sj2_oas_sql_2017080.par > impdp_djz_sj2_oas_sql_2017080.par.out &
(2) 在impdp_djz_shiju2_oas_sql_20170808.sql中找到相关sql语句,修改后在系统B中执行:
CREATE UNIQUE INDEX QAS_TEST.PK_T_LOG_TICKET_PROVINCE ON QAS_TEST.T_LOG_TICKET_PROVINCE (TICKET_ID) PCTFREE 10 INITRANS 2 MAXTRANS 255 STORAGE(INITIAL 8388608 NEXT 8388608 MINEXTENTS 1 MAXEXTENTS 2147483645 PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1 BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT) TABLESPACE DB_SBFDB_DATA3; CREATE UNIQUE INDEX QAS_TEST.PK_T_LOG_TICKET_TASK_PROVINCE ON QAS_TEST.T_LOG_TICKET_TASK_PROVINCE (TASK_ID) PCTFREE 10 INITRANS 2 MAXTRANS 255 STORAGE(INITIAL 8388608 NEXT 8388608 MINEXTENTS 1 MAXEXTENTS 2147483645 PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1 BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT) TABLESPACE DB_SBFDB_DATA3;
2、系统A的数据导入系统B时报错,用户不存在报错可忽略,本次为数据下发,非数据库重建。索引已存在是由于业务问题造成,可按照上文重命名并新建索引。
ORA-39083: Object type OBJECT_GRANT failed to create with error: ORA-01917: user or role ‘DB_DSYY‘ does not exist Failing sql is: GRANT UPDATE ON "QAS_TEST"."T_LOG_TICKET_TASK_PROVINCE" TO "DB_DSYY" Processing object type TABLE_EXPORT/TABLE/INDEX/INDEX ORA-31684: Object type INDEX:"QAS_TEST"."PK_T_LOG_TICKET" already exists ORA-31684: Object type INDEX:"QAS_TEST"."PK_T_LOG_TICKET_TASK" already exists
3、文章说明
OGG新增下发表时,需注意各个进程启动顺序,以保障数据的一致性,OGG工作顺序:源端抽取——>源端投递——>目标端应用。
