OS :CentOS Linux release 7.5

DB :Oracle 12.2.0.1.0

GSMOCI :2.2.1

本次使用三台虚拟机进行安装:

其中:

(1) db01 主机上安装Shard Director 和Shard catalog ,也就是分别安装GSM 、ORACLE 12.2 RDBMS 、non-cdb Database(GSM 和ORACLE 12.2 环境变量需要手动切换) ;

(2)db02 主机上安装Shard1 ,也就是ORACLE 12.2 RDBMS ,不需要创建数据库;

(3) db03 主机上安装Shard2 ,也就是ORACLE 12.2 RDBMS ,不需要创建数据库;

2.4 创建Shard Catalog database

在Shard catalog   服务器gsm1   创建 non-cdb 数据库。创建过程与普通数据库相同。

三:配置GSM/Shard director

https://blogs.oracle.com/database4cn/12c-oracle-sharding

3.1  解锁用户

在db01 服务器(catalog 数据库/shard director) ,连接到Sharding catalog 数据库, 解锁 GSMCATUSER 用户,shard director 通过GSMCATUSER 用户连接到shard catalog database

SQL> alter user gsmcatuser identified by oracle account unlock;

3.2 创建管理用户mygds

在 catalog 数据库,创建管理用户mygds ,用户mygds 用于存储Sharding 管理信息,GDSCTL 接口通过用户mygds 连接到catalog 数据库。

SQL> create user mygds identified by oracle;

SQL> grant connect, create session, gsmadmin_role to mygds;

SQL> grant inherit privileges on user SYS to GSMADMIN_INTERNAL;

3.3  启动listener

在db01 服务器(catalog 数据库/shard director) ,启动listener

3.4 创建shard catalog 配置remote scheduler agent

在db01 服务器(catalog 数据库/shard director) ,创建shard catalog ,在shard catalog 中配置remote scheduler agent.

参数含义:

-user : 指定管理用户,在前面步骤中创建的catalog database 管理用户mygds

-database : 指定catalog database 信息,catalog 数据库的主机名: 监听器port: catalog 数据库db_name

-sdb : 指定sharded database name

-agent_port: 设置端口,用于shard 节点agent 连接到GSM

-agent_password: 设置密码,用于shard 节点agent 连接到GSM

如果没有指定- sharding 参数,默认是创建system-managed (default) 类型

[oracle@db01 ~]$ export ORACLE_BASE=/u01/app/oracle

[oracle@db01 ~]$ export ORACLE_HOME=/u01/app/oracle/products/12.2.0/gsm_1

欢迎使用GDSCTL, 请键入 "help" 以获得信息。

当前 GSM 设置为 SHARDDIRECTOR1

GDSCTL> set gsm -gsm sharddirector1

GDSCTL>connect mygds/oracle

已建立目录连接

4.2 添加shardgroup

shardgroup 是一组shard 的集合,shardgroup 名称为primary_shardgroup ,-deploy_as primary 表示这个group 中的shard 都是主库。

GDSCTL> add shardgroup -shardgroup primary_shardgroup -deploy_as primary -region region1

操作已成功完成

4. 3 创建shard

将每个shard 地址添加到catalog 的valid node checking for registration (VNCR) 列表,并且创建shard

GDSCTL> add invitednode db02 

GDSCTL> create shard -shardgroup primary_shardgroup -destination db02 -credential cre_reg1 -sys_password oracle

操作已成功完成

数据库的唯一名称: sh2

GDSCTL> add invitednode db03

GDSCTL> create shard -shardgroup primary_shardgroup -destination db03 -credential cre_reg1 -sys_password oracle

五:创建用户和对象

5.1  在catalog 数据库中创建业务用户

---db01

SQL> alter session enable shard ddl;

SQL> create user app_schema identified by oracle;

SQL> grant all privileges to app_schema;

SQL> grant gsmadmin_role to app_schema;

SQL> grant select_catalog_role to app_schema;

SQL> grant connect, resource to app_schema;

SQL> grant dba to app_schema;

SQL> grant execute on dbms_crypto to app_schema;

5.2  创建表空间集合

---db01

SQL> conn app_schema

Enter password:

Connected.

SQL> alter session enable shard ddl;

Session altered.

SQL> create tablespace set tsp_set_1 using template (datafile size 100m autoextend on next 10m maxsize unlimited extent management local segment space management auto);

Tablespace created.

GDSCTL> set gsm -gsm sharddirector1

GDSCTL> config shard

已建立目录连接

sh2                 primary_shardgroup  确定         DDL 错误       region1   ONLINE   

sh3                 primary_shardgroup  确定         DDL 错误       region1   ONLINE   

5.3 为duplicated tables 创建表空间

--- 这个测试中duplicated table 是Products table.

SQL> CREATE TABLESPACE products_tsp datafile '/u01/app/oracle/oradata/db01/products_tsp01.dbf' size 100m autoextend on next 10M maxsize unlimited extent management local uniform size 1m;

Tablespace created.

5.4 创建 root 表 Customers

SQL > CONNECT app_schema / oracle

SQL > ALTER SESSION ENABLE SHARD DDL ;

SQL > CREATE SHARDED TABLE Customers

  (

    CustId      VARCHAR2 ( 60 ) NOT NULL ,

    FirstName   VARCHAR2 ( 60 ),

    LastName    VARCHAR2 ( 60 ),

    Class        VARCHAR2 ( 10 ),

    Geo         VARCHAR2 ( 8 ),

    CustProfile VARCHAR2 ( 4000 ),

    Passwd      RAW ( 60 ),

    CONSTRAINT pk_customers PRIMARY KEY ( CustId ),

    CONSTRAINT json_customers CHECK ( CustProfile IS JSON )

  ) TABLESPACE SET TSP_SET_1

PARTITION BY CONSISTENT HASH ( CustId ) PARTITIONS AUTO ;

5 .5 创建其他 sharded table Orders.

SQL > CREATE SHARDED TABLE Orders

  (

    OrderId     INTEGER NOT NULL ,

    CustId      VARCHAR2 ( 60 ) NOT NULL ,

    OrderDate   TIMESTAMP NOT NULL ,

    SumTotal    NUMBER ( 19 , 4 ),

    Status      CHAR ( 4 ),

    CONSTRAINT   pk_orders PRIMARY KEY ( CustId , OrderId ),

    CONSTRAINT   fk_orders_parent FOREIGN KEY ( CustId )

    REFERENCES Customers ON DELETE CASCADE

  ) PARTITION BY REFERENCE ( fk_orders_parent );  

5.6 为 OrderId 列创建序列

SQL > CREATE SEQUENCE Orders_Seq ;  

Sequence created.

5.7 创建 SHARDED TABLE LineItems

SQL > CREATE SHARDED TABLE LineItems

  (

    OrderId     INTEGER NOT NULL ,

    CustId      VARCHAR2 ( 60 ) NOT NULL ,

    ProductId   INTEGER NOT NULL ,

    Price       NUMBER ( 19 , 4 ),

    Qty         NUMBER ,

    CONSTRAINT   pk_items PRIMARY KEY ( CustId , OrderId , ProductId ),

    CONSTRAINT   fk_items_parent FOREIGN KEY ( CustId , OrderId )

    REFERENCES Orders ON DELETE CASCADE

  ) PARTITION BY REFERENCE ( fk_items_parent );

5.8 创建 duplicated tables.

---In this example , the Products table is a duplicated object.

SQL > CREATE DUPLICATED TABLE Products

  (

    ProductId  INTEGER GENERATED BY DEFAULT AS IDENTITY PRIMARY KEY ,

    Name        VARCHAR2 ( 128 ),

    DescrUri   VARCHAR2 ( 128 ),

    LastPrice  NUMBER ( 19 , 4 )

  ) TABLESPACE products_tsp ;  

5.9 检查是否有错误

六:验证环境-表空间/chunks

6.1   在db01 检查chunks 信息

前面创建shardcatalog时指定chunks为12,因此后续创建shard table分配12个chunks

GDSCTL>config chunks

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

数据库                           自         至        

---                           -         -        

sh2                           1         6        

sh3                           7         12   

6.2  在 sd1,sd2 节点检查表空间和 chunks 信息

---db02

--表空间

SQL> select TABLESPACE_NAME, BYTES/1024/1024 MB from sys.dba_data_files order by tablespace_name;

TABLESPACE_NAME               MB

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

C001TSP_SET_1                100

C002TSP_SET_1                100

C003TSP_SET_1                100

C004TSP_SET_1                100

C005TSP_SET_1                100

C006TSP_SET_1                100

PRODUCTS_TSP                 100

SYSAUX                       480

SYSTEM                       810

TSP_SET_1                100

UNDOTBS1                  70

TABLESPACE_NAME               MB

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

USERS                       5

12 rows selected.

创建了6个表空间,分别是C001TSP_SET_1 ~ 表空间C006TSP_SET_1,因为设置chunks=12,每个shard有6个chunks。

每个表空间有一个datafile,大小是100M,这个是在创建tablespace set时设置的datafile 100M。

--检查chunks

SQL> set linesize 140

SQL> column table_name format a20

SQL> column tablespace_name format a20

SQL> column partition_name format a20

SQL> show parameter db_unique_name

NAME                    TYPE  VALUE

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

db_unique_name                   string    sh2

SQL> select table_name, partition_name, tablespace_name from dba_tab_partitions

where tablespace_name like 'C%TSP_SET_1' order by tablespace_name;  2

创建了6个表空间,分别是C007TSP_SET_1 ~ 表空间C00CTSP_SET_1,因为设置chunks=12,每个shard有6个chunks。

每个表空间有一个datafile,大小是100M,这个是在创建tablespace set时设置的datafile 100M。

--检查chunks
