配置source db
4.1 配置source db参数
source db的配置主要是归档模式修改、附加日志的添加、强制日志和--ddl语句的支持。--#源端DB开启归档模式和最小附加日志 --4.1.1 源端DB开启归档模式 archive log list --#启用主动归档 -- 关闭并mount数据库 shutdown immediate startup mount -- 开启归档日志 alter database archivelog; -- 设置本地归档路径 alter system set log_archive_dest_1='location=/oradata/oggsdb/archive' scope=spfile; -- 设置归档日志文件名格式 show parameter log_archive_format ----default %t_%s_%r.dbf alter system set log_archive_format='oggsdb_%t_%s_%r.arc' scope=spfile; --关闭数据库，再启动数据库 ，使参数 log_archive_dest_1生效 shutdown immediate startup --检查配置和参数生效 archive log list show parameter log_archive_dest_1 show parameter log_archive_format -- 4.1.2 强制日志变更 alter database force logging; --实时生效 强制日志 --ALTER DATABASE NO FORCE LOGGING; -- 4.1.3 开启最小附加日志 和 查看最小附加日志 alter database add supplemental log data; --实时生效 最小附加日志 --alter database drop supplemental log data; --查看source db归档、附加日志和强制日志： select supplemental_log_data_min from v$database; select db.LOG_MODE, db.SUPPLEMENTAL_LOG_DATA_MIN, db.FORCE_LOGGING from v$database db; select db.NAME, db.LOG_MODE, db.FLASHBACK_ON, db.FORCE_LOGGING, db.supplemental_log_data_min, db.supplemental_log_data_pk, db.supplemental_log_data_ui, db.supplemental_log_data_ui, db.supplemental_log_data_fk, db.supplemental_log_data_all, db.supplemental_log_data_pl from v$database db; -- 4.1.4 修改GoldenGate参数 show parameter enable_goldengate_replication alter system set enable_goldengate_replication = true scope = both; show parameter enable_goldengate_replication -- 4.1.5 创建GoldenGate用户 create tablespace ogg_data datafile '/oradata/oggsdb/ogg_data01.dbf' size 50M autoextend on next 8M; create user ogg identified by Password123 default tablespace ogg_data quota unlimited on ogg_data; 授权GoldeGate用户 ： grant connect, resource to ogg; grant alter any table, alter system,alter user, create session, alter session to ogg; grant select any dictionary, SELECT ANY TRANSACTION,select any table,flashback any table to ogg; --grant DBA to ogg; -- DDL and sequence support --GRANT FLASHBACK ANY TABLE TO db_user --GRANT FLASHBACK ON schema.table TO db_user --11.2.0.4 or later需要执行以下package 权限 ： begin dbms_goldengate_auth.grant_admin_privilege(grantee => 'OGG', privilege_type => 'CAPTURE', grant_select_privileges => TRUE, do_grants => TRUE); END; / /*----此包dbms_goldengate_auth.grant_admin_privilege授予权限如下18个权限： -- Grant/Revoke object privileges grant execute on LOGMNR$COL_GG_TABF_PUBLIC to OGG; grant execute on LOGMNR$GSBA_GG_TABF_PUBLIC to OGG; grant execute on LOGMNR$KEY_GG_TABF_PUBLIC to OGG; grant execute on LOGMNR$SEQ_GG_TABF_PUBLIC to OGG; grant execute on LOGMNR$TAB_GG_TABF_PUBLIC to OGG; grant insert on LOGMNR_RESTART_CKPT$ to OGG; -- Grant/Revoke role privileges grant select_catalog_role to OGG; -- Grant/Revoke system privileges grant alter any table to OGG; grant alter session to OGG; grant create evaluation context to OGG with admin option; grant create job to OGG; grant create rule to OGG with admin option; grant create rule set to OGG with admin option; grant dequeue any queue to OGG with admin option; grant execute any rule set to OGG with admin option; grant flashback any table to OGG; grant logmining to OGG; grant select any table to OGG; */ --4.1.6 配置DDL语句支持 ( Support for DDL Capture in Classic Capture Mode ) --Classic capture mode requires the use of the Oracle GoldenGate DDL trigger to --capture DDL from an Oracle Database. Native DDL capture is not supported by classic capture mode. --授权GoldeGate用户 ：(除以上 4.1.5 授权部分外，还需要 DBA 权限 支持 DDL and sequence 捕获) --a. --创建存放ddl信息的GoldenGate用户： ( 如上 共用 ogg 用户 ) --create tablespace ogg_data datafile '/oradata/oggsdb/ogg_data01.dbf' size 50M autoextend on next 8M; --create user ogg identified by Password123 default tablespace ogg_data quota unlimited on ogg_data; --b. 此可暂时忽略 -- (Optional)To cause user DDL activity to fail when the DDL tablespace fills up, edit the params.sql script -- and set the ddl_fire_error_in_trigger parameter to TRUE. As a best practice, make certain to size the tablespace appropriately in the first place. #params.sql内容 define the ddl_fire_error_in_trigger = 'TRUE' define allow_invisible_index_keys = 'TRUE' #To enable trigger-based DDL replication to recognize Oracle invisible indexes as #unique identifiers, set the following parameter to TRUE in the params.sql script: --c. 此可暂时忽略 --#at the root of the Oracle GoldenGate directory. Do not alterthe file name or location. EDIT PARAMS ./GLOBALS # 内容 GGSCHEMA schema_name ##Save and close the GLOBALS file and the params.sql file. --d. grant dba to ogg ; GRANT EXECUTE ON utl_file TO ogg; #Change directories to the Oracle GoldenGate installation directory. # ----The specific location is: oggma_install_home/lib/sql/legacy. #Exit all Oracle sessions.

4.2 配置source db manager进程
--EXTRACT exoggs
--SETENV (ORACLE_HOME="/orabin/product/12.2.0.1")
--SETENV (ORACLE_SID = "OGGSDB")
进入GoldenGatean安装目录，创建工作区目录：
cd $OGG_HOME
./ggsci
GGSCI (dbserver) 1> create subdirs
Creating subdirectories under current directory /oradata/ogg
Parameter file /oradata/ogg/dirprm: created.
Report file /oradata/ogg/dirrpt: created.
Checkpoint file /oradata/ogg/dirchk: created.
Process status files /oradata/ogg/dirpcs: created.
SQL script files /oradata/ogg/dirsql: created.
Database definitions files /oradata/ogg/dirdef: created.
Extract data files /oradata/ogg/dirdat: created.
Temporary files /oradata/ogg/dirtmp: created.
Credential store files /oradata/ogg/dircrd: created.
Masterkey wallet files /oradata/ogg/dirwlt: created.
Dump files /oradata/ogg/dirdmp: created.
GGSCI (dbserver) 2>
--创建数据目录(可在dirdat目录下为 oggsdb的抽取进程创建一个单独数据存放目录 )
--cd $OGG_HOME
--oracle[/oradata/ogg]$mkdir -p dirdat/oggsdb
---- /oradata/ogg/dirdat/oggsdb
编辑配置manager参数文件 ：
GGSCI > edit params mgr
添加以下内容
PORT 7809
DYNAMICPORTLIST 7800-7900
ACCESSRULE, PROG , IPADDR 192.168.6.20, ALLOW
ACCESSRULE, PROG SERVER, ALLOW
--PURGEOLDEXTRACTS ./dirdat/oggsdb/ex, usecheckpoints, minkeephours 12 #### 参数 minkeepdays 2

AUTORESTART EXTRACT *, RETRIES 5, WAITMINUTES 2, RESETMINUTES 60
lagreporthours 1
laginfominutes 30

*/
对需要的表添加trandata
cd $OGG_HOME
./ggsci
GGSCI > dblogin userid ogg@oggsdb password Password123
Successfully logged into database.
GGSCI > add trandata scott.emp
--info trandata scott.emp
--select * from DBA_LOG_GROUPS
4.3 配置source db extract进程
--select * from nls_database_parameters
添加一个extract进程 ：
GGSCI > add extract exggsdb,tranlog,begin now ----, threads 2
编辑extract参数文件：
GGSCI (dbserver) 13> edit params exggsdb
添加以下内容
extract exggsdb
setenv (ORACLE_SID = "OGGSDB")
setenv (NLS_LANG = "AMERICAN_AMERICA.AL32UTF8")
userid ogg@oggsdb, password Password123
TRANLOGOPTIONS DBLOGREADER
reportcount every 30 minutes, rate
discardrollover at 3:00
warnlongtrans 2h, checkinterval 300
exttrail /oradata/ogg/dirdat/oggsdb/ex
discardfile /oradata/ogg/dirdat/exggsdb.dsc, append, megabytes 100
--gettruncates ---- DDL support parameter
getupdatebefores
nocompressdeletes
nocompressupdates
--LOGALLSUPCOLS
dboptions allowunusedcolumn
fetchoptions nousesnapshot
fetchoptions fetchpkupdatecols
table SCOTT.EMP;
创建本地trail文件 ：
GGSCI > add exttrail /oradata/ogg/dirdat/oggsdb/ex, extract exggsdb
EXTTRAIL added.
4.4 配置source db pump进程
添加一个pump进程（本质上也是extract进程），并指定远程trail文件：
GGSCI > add extract ppggsdb,exttrailsource /oradata/ogg/dirdat/oggsdb/ex
EXTRACT added.
编辑pump参数文件：
GGSCI (dbserver) 16> edit params ppggsdb
添加以下内容
extract ppggsdb
passthru
rmthost 192.168.6.20, mgrport 7809 ---- target db主机ip，管理进程端口号 ##共用同一台主机的mgr进程 测试
rmttrail /oradata/ogg/dirdat/oggtdb/pp
--ddl -- DDL support parameter
table scott.emp;
指定远程trail文件：
GGSCI > add rmttrail /oradata/ogg/dirdat/oggtdb/pp, extract ppggsdb
RMTTRAIL added.
4.5 启动source进程
查看extrac进程，启动进程后注意查看ggserr.log的日志信息，确认无警告错误，启动pump进程需先启动target db的mgr进程，否则会报错无法启动：
开一个命令行：
cd $OGG_HOME
tail -f 50 ggserr.log
再开一个命令行：
cd $OGG_HOME
./ggsci
GGSCI > info all
GGSCI > start mgr
GGSCI > start exggsdb
GGSCI > start ppggsdb
GGSCI > info all
##########同一台主机，两个oracle数据库测试(source --> target), 可以共用OGG MGR 进程?!
##########若 源数据库 和 目标数据库 在不同主机，目标端也需要安装OGG ，并配置OGG 数据目录。
