GoldenGate 12.2抽取Oracle 12c多租户配置过程

linux下安装12c

重启linux之后，dbca

PDB/CDB使用

SQL> select instance_name from v$instance;

INSTANCE_NAME

------------------------------------------------

GORCL

SQL> alter pluggable database p_orcl open;

Pluggable database altered.

SQL> alter session set container=p_orcl;

Session altered.

SQL> select con_id,dbid,NAME,OPEN_MODE from v$pdbs;

CON_ID DBID NAME OPEN_MODE

--------- ---------- --------------------------------------------------------------------------- ------------------------------

4 1842197265 P_ORCL READ WRITE

SQL> create user test identified by test;

User created.

SQL>create user hr identified by hr;

Create table test.t1(id int primary key, name varchar2(50));

Create table hr.t2(id int primary key, name varchar2(50));

SQL> alter session set container=cdb$root;

Session altered.

SQL> alter PLUGGABLE database all open;

Pluggable database altered.

SQL> select con_id,dbid,NAME,OPEN_MODE from v$pdbs;

CON_ID DBID NAME OPEN_MODE

---------- ---------- ------------------------------------------------------------------------------ ------------------------------

2 2940647386 PDB$SEED READ ONLY

3 1813216422 C_ORCL READ WRITE

4 1842197265 P_ORCL READ WRITE

然后在listener.ora, tnsnames.ora中，dbname因为CDB, PDB是不同的，可以单独配置。以下是listener.ora

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(GLOBAL_DBNAME = G_ORCL)

(ORACLE_HOME = /app/oracle/product/12.1.0/dbhome_1)

(SID_NAME = GORCL)

)

(SID_DESC =

(SID_NAME = CLRExtProc)

(ORACLE_HOME = /app/oracle/product/12.1.0/dbhome_1)

(PROGRAM = extproc)

)

(SID_DESC =

(GLOBAL_DBNAME = P_ORCL)

(ORACLE_HOME = /app/oracle/product/12.1.0/dbhome_1)

(SID_NAME = GORCL)

)

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.89.134)(PORT = 1521))

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))

)

以下是tnsnames.ora

PORCL =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.89.134)(PORT = 1521))

)

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = G_ORCL)

)

GORCL =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.89.134)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = G_ORCL)

)

所以使用tnsping是针对上面tnsnames.ora中的设置建立的，都是指向同一个service，因此其实只有一个service。

直接连接到PDB的方法如下：

OGG12.2 安装

原理

OGG针对db12c多租户只需要配置一个extract，指向多个pdb；然后使用多个传输进程传输不同PDB的数据到目标端，当然也可以只用一个传输进程。
目标端针对不同的PDB，必须配置不同的rep进程。

源端DB准备

SQL>Alter database archivelog;

SQL>Alter database force logging;

SQL>Alter database add supplemental log data;

SQL>Alter system switch logfile;

SQL>alter system set enable_goldengate_replication=true;

SQL>create user C##ogg identified by ogg;

SQL>grant connect, create session, resource to c##ogg;

SQL>exec dbms_goldengate_auth.grant_admin_privilege(‘C##OGG’,container=>’all’)

SQL>grant dba to c##ogg container=all;

测试表

源端

测试表

PDB: P_orcl

Test.t1

Hr.t2

Pdb: pdb3

SQL>create user p3 identified by p3;

SQL>create table p3.t3 (id int primary key, name varchar2(50));

目标端

Pdb: pdb4

Dba user: pdb4_admin

SQL>Alter session set container=pdb4;

SQL>create user p4 identified by p4;

SQL>create table p4.t4 (id int primary key, name varchar2(50));

sqlplus / as sysdba

SQL> alter session set container=pdb4;

Session altered.

SQL> grant dba to pdb4_admin container=pdb4;

Grant succeeded.

SQL> conn pdb4_admin/pdb4_admin as sysdba;

Connected.

conn pdb4_admin/pdb4_admin@192.168.89.134:1521/pdb4 as sysdba;

配置

Credential store配置

GGSCI (localhost.localdomain) 27> create wallet

Created wallet at location 'dirwlt'.

Opened wallet at location 'dirwlt'.

GGSCI (localhost.localdomain) 28> ADD MASTERKEY

Master key 'OGG_DEFAULT_MASTERKEY' added to wallet at location 'dirwlt'.

GGSCI (localhost.localdomain) 29> INFO MASTERKEY

Masterkey Name: OGG_DEFAULT_MASTERKEY

Creation Date: Mon Oct 20 20:51:23 2014

Key Hash (SHA1): 0x2E491E86DA7A0C0D767360B2B8C07968AD9A14BF

拷贝wallet目录dirwlt到其它系统，这样所有系统的认证信息相同。在其它系统确认masterkey的版本及key hash是相同的。

GGSCI (localhost.localdomain) 50> add credentialstore
