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;

GSM 下载
二:安装GSM/Shard catalog/ORACLE 12.2 RDBMS
2.1 Gsm 安装
2.2 ORACLE 12.2 RDBMS 安装
略
2.3 创建并启动监听
Netca
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
[oracle@db01 ~]$
export PATH=/u01/app/oracle/products/12.2.0/gsmh_11/bin:$PATH:$HOME/bin

GDSCTL: Version 12.2.0.1.0 - Production on Mon Feb 25 10:38:54 CST 2019
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 创建和启动shard director
参数含义:
-gsm: 指定shard director 名称
-listener: 指定shard director 的监听端口,注意不能与数据库的listener 端口冲突
-catalog: 指定catalog database 信息,catalog 数据库的主机名: 监听器port: catalog 数据库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 已成功启动
3.6 添加操作系统认证
GDSCTL> add credential -credential cre_reg1 -osaccount oracle -ospassword oracle
操作已成功完成
3.7 在所有的shard 节点分别执行Agent
--- 在db02 节点执行
[oracle@db02 ~]$ schagent -start
Scheduler agent started using port 24409
[oracle@db02 ~]$ schagent -status
Agent running with PID 8537

--- 在db03 节点执行
[oracle@db03 ~]$ schagent -start
Scheduler agent started using port 19249
[oracle@db03 ~]$ schagent -status

----- 密码oracle 和端口8080
[oracle@db02 ~]$ echo oracle | schagent -registerdatabase 192.168.2.226 8080
Agent Registration Password ?
Oracle Scheduler Agent Registration for 12.2.0.1.2 Agent
Agent Registration Successful!
[oracle@db03 ~]$ echo oracle | schagent -registerdatabase 192.168.2.226 8080
Agent Registration Password ?
Oracle Scheduler Agent Registration for 12.2.0.1.2 Agent
Agent Registration Successful!
3.8 创建shard 数据库的数据文件存储路径
[oracle@db02 ~]$ mkdir /u01/app/oracle/oradata
[oracle@db02 ~]$ mkdir /u01/app/oracle/fast_recovery_area
[oracle@db03 ~]$ mkdir /u01/app/oracle/oradata
[oracle@db03 ~]$ mkdir /u01/app/oracle/fast_recovery_area
四:创建System-Managed SDB
4.1 连接gsm
在Shard 服务器 sd1 连接到shard director/GSM 服务器(db01)
[oracle@db02 ~]$ ssh oracle@db01
……
oracle@db01's password:
Last login: Mon Feb 25 10:45:20 2019 from 192.168.70.249
[oracle@db01 ~]$ source .bash_profile
[oracle@db01 ~]$ gdsctl

版权所有 (c) 2011, 2016, Oracle 。保留所有权利。
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
操作已成功完成
数据库的唯一名称: sh3

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

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 ;
