Oracle 12C Sharding部署和測試

OS :CentOS Linux release 7.5

DB :Oracle 12.2.0.1.0

GSMOCI :2.2.1

本次使用三臺虛擬機進行安裝:

其中:

(1) db01 主機上安裝Shard Director 和Shard catalog ,也就是分別安裝GSM 、ORACLE 12.2 RDBMS 、non-cdb Database(GSM 和ORACLE 12.2 環境變量需要手動切換) ;

(2)db02 主機上安裝Shard1 ,也就是ORACLE 12.2 RDBMS ,不需要創建數據庫;

(3) db03 主機上安裝Shard2 ,也就是ORACLE 12.2 RDBMS ,不需要創建數據庫;

2.2 ORACLE 12.2 RDBMS 安裝

2.3 創建并啟動監聽

Netca

2.4 創建Shard Catalog database

在Shard catalog   服務器gsm1   創建 non-cdb 數據庫。創建過程與普通數據庫相同。

三:配置GSM/Shard director

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

3.1  解鎖用戶

在db01 服務器(catalog 數據庫/shard director) ,連接到Sharding catalog 數據庫, 解鎖 GSMCATUSER 用戶,shard director 通過GSMCATUSER 用戶連接到shard catalog database

SQL> alter user gsmcatuser identified by oracle account unlock;

3.2 創建管理用戶mygds

在 catalog 數據庫,創建管理用戶mygds ,用戶mygds 用于存儲Sharding 管理信息,GDSCTL 接口通過用戶mygds 連接到catalog 數據庫。

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  啟動listener

在db01 服務器(catalog 數據庫/shard director) ,啟動listener

3.4 創建shard catalog 配置remote scheduler agent

在db01 服務器(catalog 數據庫/shard director) ,創建shard catalog ,在shard catalog 中配置remote scheduler agent.

參數含義:

-user : 指定管理用戶,在前面步驟中創建的catalog database 管理用戶mygds

-database : 指定catalog database 信息,catalog 數據庫的主機名: 監聽器port: catalog 數據庫db_name

-sdb : 指定sharded database name

-agent_port: 設置端口,用于shard 節點agent 連接到GSM

-agent_password: 設置密碼,用于shard 節點agent 連接到GSM

如果沒有指定- sharding 參數,默認是創建system-managed (default) 類型

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

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

[oracle@db01 ~]$

Copyright (c) 2011, 2016, Oracle.  All rights reserved.

Welcome to GDSCTL, type "help" for information.

Warning: current GSM name is not set automatically because gsm.ora contains zero or several GSM entries. Use "set  gsm" command to set GSM for the session.

Current GSM is set to GSMORA

GDSCTL> create shardcatalog -database db01:1521:db01 -chunks 12 -user mygds/oracle -sdb shdb -region region1, region2 -agent_port 8080 -agent_password oracle

Catalog is created

3.5  創建和啟動shard director

參數含義:

-gsm: 指定shard director 名稱

-listener: 指定shard director 的監聽端口,注意不能與數據庫的listener 端口沖突

-catalog: 指定catalog database 信息,catalog 數據庫的主機名: 監聽器port: catalog 數據庫db_name

GDSCTL> add gsm -gsm sharddirector1 -listener 1522 -pwd oracle -catalog db01:1521:db01 -region region1

GSM successfully added

GDSCTL> start gsm -gsm sharddirector1

GSM 已成功啟動

3.6  添加操作系統認證

GDSCTL> add credential -credential cre_reg1 -osaccount oracle -ospassword oracle

操作已成功完成

3.7 在所有的shard 節點分別執行Agent

--- 在db02 節點執行

[oracle@db02 ~]$ schagent -start

當前 GSM 設置為 SHARDDIRECTOR1

GDSCTL> set gsm -gsm sharddirector1

GDSCTL>connect mygds/oracle

已建立目錄連接

4.2 添加shardgroup

shardgroup 是一組shard 的集合,shardgroup 名稱為primary_shardgroup ,-deploy_as primary 表示這個group 中的shard 都是主庫。

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

操作已成功完成

4. 3 創建shard

將每個shard 地址添加到catalog 的valid node checking for registration (VNCR) 列表,并且創建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

數據庫的唯一名稱: sh2

GDSCTL> add invitednode db03

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

五:創建用戶和對象

5.1  在catalog 數據庫中創建業務用戶

---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  創建表空間集合

---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

已建立目錄連接

sh2                 primary_shardgroup  確定         DDL 錯誤       region1   ONLINE   

sh3                 primary_shardgroup  確定         DDL 錯誤       region1   ONLINE   

5.3 為duplicated tables 創建表空間

--- 這個測試中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 創建 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 創建其他 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 為 OrderId 列創建序列

SQL > CREATE SEQUENCE Orders_Seq ;  

Sequence created.

5.7 創建 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 創建 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 ;

創建了6個表空間,分別是C001TSP_SET_1 ~ 表空間C006TSP_SET_1,因為設置chunks=12,每個shard有6個chunks。

每個表空間有一個datafile,大小是100M,這個是在創建tablespace set時設置的datafile 100M。
