target db:
ip:192.168.6.20
db type:Oracle db 12.2.0.1.0

GoldenGate:
ogg type:GoldenGate for Oracle 19.1.0.0.4

  1. 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 :

                                                    grant_select_privileges => TRUE,
                                                    do_grants             => TRUE);

       */
     
     
     --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)

     --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. Prevent the start of any new sessions.
     进入GoldenGate目录,调用SQL脚本:
     cd $OGG_HOME
     sqlplus / as sysdba
     
     SQL> @marker_setup.sql;
     #输入准备好的用户ogg
     
     SQL> @ddl_setup.sql;
     #输入准备好的用户ogg 
     
     SQL> @role_setup.sql;
     #输入准备好的用户ogg 
     #Grant the role that was created (default name is GGS_GGSUSER_ROLE) to all Oracle GoldenGate Extract users.
     #根据上面执行结果的提示授权角色给ogg用户
     SQL> grant GGS_GGSUSER_ROLE to ogg;
     
     
     SQL> @ddl_enable.sql;
     
     ##To Install and Use the Optional Performance Tool
     SQL> @ddl_pin ogg
     至此,ddl语句的支持配置完成。
     
     #验证DDL安装 --运行marker_status.sql校验DDL的状态
     SQL> @marker_status.sql

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.

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

*/

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。

  1. 配置target db
