1.1    Configure Oracle Database for Goldengate

1.1.1  Create Goldengate user

Create user ogg for both source system and target system, and grant appropriate privileges.

为源库和目标库创建ogg用户并赋予相应权限。

1.1.1.1 For Source System(PROD):

创建表空间;创建用户、赋予权限

[oracle@rhel101 ~]$ sqlplus / as sysdba

SYS@PROD>create tablespace tbs_gguser datafile

'/u01/app/oracle/oradata/PROD/gguser.dbf' size 50m autoextend on;

SYS@PROD>create user ogg identified by ogg default tablespace tbs_gguser

  2  temporary tablespace TEMP quota unlimited on tbs_gguser;

SYS@PROD>grant connect,resource to ogg;

SYS@PROD>grant alter session to ogg;

SYS@PROD>grant select any table,select any dictionary,alter any table to ogg;

SYS@PROD>grant flashback any table to ogg;

SYS@PROD>grant execute on dbms_flashback to ogg;


Create test table for Source System:

为源库创建测试表、插入数据、创建主键约束

SYS@PROD>conn scott/tiger

SCOTT@PROD>create table ggtab as select * from emp;

SCOTT@PROD>alter table ggtab add constraint pk_ggtab_empno primary key(empno);

SCOTT@PROD>select * from ggtab;

 

1.1.1.2 For Target System(EMREP):

创建表空间;创建用户、赋予权限

[oracle@rhel102 ~]$ sqlplus / as sysdba

 

SYS@EMREP>create tablespace tbs_gguser datafile

  2  '/u01/app/oracle/oradata/EMREP/gguser.dbf' size 50m autoextend on;

SYS@EMREP>create user ogg identified by ogg default tablespace tbs_gguser

  2  temporary tablespace TEMP quota unlimited on tbs_gguser;

SYS@EMREP>grant connect,resource to ogg;

SYS@EMREP>grant alter session to ogg;

SYS@EMREP>grant select any dictionary, select any table to ogg;

SYS@EMREP>grant update any table,delete any table,insert any table to ogg;


Create empty test table

SYS@EMREP>conn scott/tiger

SCOTT@EMREP>create table ggtab as select * from emp where 1=2;

SCOTT@EMREP>alter table ggtab add constraint pk_ggtab_empno primary key(empno);


1.1.2  Enable supplemental log mode in source system

Check that supplemental log mode is enabled by following query:

SYS@PROD>select supplemental_log_data_min from v$database;

SUPPLEME

--------

NO

If not, enable it:

SYS@PROD>alter database add supplemental log data;

SYS@PROD>alter system switch logfile;

SYS@PROD>select supplemental_log_data_min from v$database;

1.1.3  Enable archive log mode in source system

Enable archive log mode:          

[oracle@rhel101 ~]$ mkdir /u01/app/oracle/arch

[oracle@rhel101 ~]$ ls -ld /u01/app/oracle/arch

 

SYS@PROD>alter system set log_archive_dest_1='location=/u01/app/oracle/arch';

SYS@PROD>shutdown immediate;

SYS@PROD>startup mount;

SYS@PROD>alter database archivelog;

SYS@PROD>alter database open;

SYS@PROD>alter system archive log current;

SYS@PROD>archive log list;


1.1.4  Enable force logging mode in source system

Enable force logging mode:            in case of "no logging" operations

SYS@PROD>alter database force logging;

SYS@PROD>select force_logging from v$database;

 

1.1.5  Enable transaction data change capture for test table in Source system

GGSCI (rhel101.oracle.com) 11> dblogin userid ogg,password ogg

Successfully logged into database.

GGSCI (rhel101.oracle.com) 12> add trandata scott.ggtab

Logging of supplemental redo data enabled for table SCOTT.GGTAB.

GGSCI (rhel101.oracle.com) 13> info trandata scott.ggtab

Logging of supplemental redo log data is enabled for table SCOTT.GGTAB.

Columns supplementally logged for table SCOTT.GGTAB: EMPNO.


1.2    Configure Goldengate Manager Process

1.2.1  Configure MGR in source system

Create the Manager parameter file.

[oracle@rhel101 11.2.1]$ ggsci

GGSCI (rhel101.oracle.com) 1> edit params mgr


Use the editor to assign a port.
此端口号对应 对端的pump配置端口号

PORT 7809

PURGEOLDEXTRACTS ./dirdat, USECHECKPOINTS

Start the Manager 

GGSCI (rhel101.oracle.com) 2> start mgr

Verify that the Manager has started.

GGSCI (rhel101.oracle.com) 3> info mgr

Manager is running (IP port rhel101.oracle.com.7809).

1.2.2  Configure MGR in target system

Create the Manager parameter file.

GGSCI (rhel102.oracle.com) 5> edit params mgr

PORT 7809

PURGEOLDEXTRACTS /u01/app/oracle/ggs/11.2.1/dirdat, USECHECKPOINTS


Start the Manager.

GGSCI (rhel102.oracle.com) 6> start mgr

GGSCI (rhel102.oracle.com) 7> info mgr

Manager is running (IP port rhel102.oracle.com.7809).


GGSCI (rhel102.oracle.com) 2> start mgr

Verify that the Manager has started.

GGSCI (rhel102.oracle.com) 3> info mgr

Manager is running (IP port rhel102.oracle.com.7809).

1.3    Load Initial Data by Direct Load method

1.3.1  Configure Extract process in source system

Add an Extract process called EINI_1:

GGSCI (rhel101.oracle.com) 2> add extract eini_1,sourceistable

EXTRACT added.

GGSCI (rhel101.oracle.com) 3> info extract *,tasks

EXTRACT    EINI_1    Initialized   2017-01-05 09:25   Status STOPPED

Checkpoint Lag       Not Available

Log Read Checkpoint  Not Available

                     First Record         Record 0

Task                 SOURCEISTABLE

 


Edit EINI_1:

GGSCI (rhel101.oracle.com) 6> edit params eini_1

Add:

-- GoldenGate Initial Data Capture

-- for scott.ggtab

EXTRACT EINI_1

SETENV (NLS_LANG=AMERICAN_AMERICA.AL32UTF8)

USERID ogg, PASSWORD ogg

RMTHOST rhel102.oracle.com, MGRPORT 7809

RMTTASK REPLICAT, GROUP RINI_1

TABLE scott.ggtab;

For chinese support, we should set environment variable “NLS_LANG” in Extract/Pump/Replicat process parameters.

1.3.2  Configure replicat process in target system rini_1

Add initial load delivery process

GGSCI (rhel102.oracle.com) 4> add replicat rini_1,specialrun

REPLICAT added

GGSCI (rhel102.oracle.com) 4> info replicat *,tasks

REPLICAT   RINI_1    Initialized   2017-01-05 09:30   Status STOPPED

Log Read Checkpoint  Not Available

Task                 SPECIALRUN

Edit initial load delivery process RINI_1.

GGSCI (rhel102.oracle.com) 6> edit params rini_1

Add:

-- GoldenGate Initial Load Delivery

REPLICAT RINI_1

SETENV (NLS_LANG=AMERICAN_AMERICA.AL32UTF8)

ASSUMETARGETDEFS

USERID ogg, PASSWORD ogg

DISCARDFILE ./dirrpt/RINIaa.dsc, PURGE

MAP scott.*, TARGET scott.*;

Note: In the MAP statement, the first owner/schema is for the source and the second for the target.

1.3.3  Accomplish Initial Load

Start Initial Load process EINI_1 insource system, then RINI_1 process in target system will be started automatically:

GGSCI (rhel101.oracle.com) 6> start extract eini_1

Sending START request to MANAGER ...

EXTRACT EINI_1 starting

GGSCI (rhel101.oracle.com) 7> info extract eini_1

EXTRACT    EINI_1    Initialized   2017-01-05 09:25   Status RUNNING

Checkpoint Lag       Not Available

Log Read Checkpoint  Not Available

                     First Record         Record 0

Task                 SOURCEISTABLE


1.3.4  Verify Initial Load result and process status

 GGSCI (rhel101.oracle.com) 11> view report eini_1

2017-01-05 09:35:06  INFO    OGG-01017  Wildcard resolution set to IMMEDIATE because SOURCEISTABLE is used.

Check process status

After initial load, extract process EINI_1 and replicat process RINI_1 stop automatically.

1.3.6  Solution for Error


eini_1 parameter  should put the parent table first
,for example:

EXTRACT EINI_1

SETENV (NLS_LANG=AMERICAN_AMERICA.ZHS16GBK)

RMTHOST lvxingaho2, MGRPORT 7809

RMTTASK REPLICAT, GROUP RINI_1

1.4    Configure Extract Process in Source system

1.4.1  Edit extract process parameter eora_1

GGSCI (rhel101.oracle.com) 15> edit params eora_1

Add:

-- Change Capture parameter file to capture ggtbs changes

EXTRACT EORA_1

Please note that “la” is prefix for local trail file.

GGSCI (rhel101.oracle.com) 69> view params eora_1


Execute the following commands in source system to add Primary Extract group.

GGSCI (rhel101.oracle.com) 16> add extract eora_1,tranlog,begin now

EXTRACT added.

1.4.2  Define GoldenGate local trail

GGSCI (rhel101.oracle.com) 17> ADD EXTTRAIL ./dirdat/la, EXTRACT EORA_1, MEGABYTES 5

EXTTRAIL added.

1.4.3  Start primary Extract process

GGSCI (rhel101.oracle.com) 18> start extract eora_1

Sending START request to MANAGER ...
