Oracle12c Sharding技术实现了跨数据库级别的数据分片，实现了分布式IO大数据扩展的云数据库架构体系，可满足大数据海量存储、分布式数据读写以及满足Scale Out/ScaleUp扩展性需求。Sharding的主要特点：
线性伸缩性（Scale out）：Sharding技术减少性能瓶颈，同时可以通过添加Shard节点的方式扩展容量和性能；
错误纠正机制：Sharding是基于非共享物理资源的架构设计，有效消除了单点故障，例如共享磁盘以及SAN存储扥。它的错误纠正机制保证了单个Shard故障不会影响整个集群的使用和性能
地域分布式数据：Sharding可以将数据就近存储在消费者的同时，可以有效的满足监管范围内的管控需要
滚动式更新：应用更新一次仅在一个Shard节点上进行，不会影响其他节点，这样可以保证在小部分数据更新时，可以及时进行数据验证。
简化云发布：Sharding可以简化云发布
Oracle12c 应用程序通过数据库pool将数据库在逻辑层当做1个数据库：数据、事务、用户以及所有Level，通过将Shards添加到pool。Oracle12c支持1000个Shards。
Sharding技术是数据层架构体系，在各个数据库间进行垂直分片。Sharding主要组成结构如下:
其中：
SDB（Sharded database）：一个逻辑层的数据库，该数据库跨越多个物理分片数据库（Shard）组成的数据池进行水平分区。
Shards：独立的物理数据库集（SDB）组成节点。
ShardCatalog - 它也是一个Oracle Database，主要用于Shard的自动部署、集中管理以及跨Shard的查询。
ShardDirectors - 跟据Sharding Key来提供到Shard的路由。OracleSharding中可以设置多个位于不同Host的Shard Director。
Sharding环境部署1.在各个节点/etc/hosts目录追加记录：
192.168.43.101 shard1(Oracle软件+Client[agent])
192.168.43.102 shard2(Oracle软件+Client[agent])
192.168.43.200 sdb1(Oracle软件+GSM[安装shard catlog和shard directory])
SDB1主机安装shardcat实例（db）和gsm服务软件
2.在SDB 节点安装Oracle软件12c,在shard节点安装schagent
2.1SDB安装Oracle软件参考12c安装Installing OracleDatabase Software
配置$ORACLE_HOME/schagent.conf
选择client安装包（linuxx64_12201_client.zip），解压缩后，运行runInstaller，在每个shard node上建立agent
3.安装共享目录软件【GDS/GSM】(gsm：global service manager)

注意：GSM安装必须使用操作系统中单独的用户（Linux），不能使用Root安装，一般使用oracle用户
详细安装步骤：
3.1.安装GSM
3.1.1配置gsm和shardcat数据库的环境变量（都使用oracle安装）
exportORACLE_BASE=/u01/app/oracle
exportORACLE_HOME=/u01/app/oracle/product/12.2.0/dbhome_1
exportGSM_HOME=/u01/app/oracle/product/12.2.0/gsm
exportORACLE_SID=shardcat
exportPATH=$ORACLE_HOME/bin:$GSM_HOME/bin:$PATH
exportORACLE_TERM=xterm
exportTNS_ADMIN=$ORACLE_HOME/network/admin

4 创建分片目录数据库
Creatingthe Shard Catalog Database
--指定非CDB模式
---选择OMF
--设置归档和闪回
--安装完数据库后查看(non-CDB模式)：
SQL> show con_name;
CON_NAME
------------------------------
shardcat
5.配置分片管理和路由层
Setting Upthe Oracle Sharding Management and Routing Tier
The shard catalog,shard directors and shards must be configured to communicate with each other
分片目录、分片文件夹以及shard节点必须能够保证互相通讯。通过以下步骤实现：
5.1确认分片数据库环境
[oracle@sdb1 ~]$ env|grep ORA
ORACLE_SID=shardcat
ORACLE_BASE=/u01/app/oracle
ORACLE_TERM=xterm
ORACLE_HOME=/u01/app/oracle/product/12.2.0/dbhome_1
5.2.启动shard catalog监听（shardcat实例）
lsnrctl start
5.3验证/设置参数 DB_CREATE_FILE_DEST/open_links/open_links_per_instance
Verify thatDB_CREATE_FILE_DEST parameter is set on the shard catalog database.
If the parameter is notset, then set it as shown in the following example. Note that open_links andopen_links_per_instance are set to 16 for the purposes of the Oracle Shardingdemo application.

SQL> alter systemset open_links=16 scope=spfile;
SQL> alter systemset open_links_per_instance=16 scope=spfile;
------------
5.4重启数据库
startup force;
5.5在分片目录数据库中授权（gsmcatuser/mysdbadmin）
Grant rolesand privileges on the shard catalog database
--------
SQL> set echo on
SQL> set termout on
SQL> spoolsetup_grants_privs.lst
5.5.1.Unlockand set the password for the GSMCATUSER schema.
解锁GSMCATUSER用户，该用户用于分片文件夹连接到分片目录数据库
This schema is used bythe shard director when connecting to the shard catalog database.
SQL> alter user gsmcatuseraccount unlock;
SQL> alter usergsmcatuser identified by oracle;
5.5.2.Createthe administrator schema and grant privileges to it.
创建mysdbadmin用户，该用户管理分片目录数据库环境。GDSCTL命令就是使用该用户来连接数据库的
The mysdbadmin accountis an account in the shard catalog database which stores information on thesharding environment. The mysdbadmin account is the database administratorschema for making administrative changes to the sharded database environment.GDSCTL connects through this user to the database when GDSCTL commands are run,and the mysdbadmin user makes the necessary changes in the database.
SQL> create usermysdbadmin identified by oracle;
SQL> grant connect,create session, gsmadmin_role to mysdbadmin;
SQL> grant inheritprivileges on user SYS to GSMADMIN_INTERNAL;
SQL> spool off

7. 连接到分片目录主机，启动GDSCTL工具
The commands in thefollowing steps are executed from a shard director host because the GDSCTLcommand line interface is installed there.
The following exampleincludes a sanity check that environment variables have been set properly.
$ env |grep ORA
ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=/u01/app/oracle/product/12.2.0/gsmhome_1
$ gdsctl
7.1 创建分片目录，同事配置远程调度
GDSCTL> createshardcatalog -database shard_catalog_host:1521:shard_catalog_name -chunks12 -usermysdbadmin/mysdbadmin_password
-sdb cust_sdb -region region1, region2 -agent_port port_num -agent_passwordrsa_password
---------------
--create shardcatalog-database sdb1:1521:shardcat -chunks 12 -user mysdbadmin/oracle -sdb sdb1 -region region1, region2-agent_port 8080 -agent_password oracle
其中：
-database 创建catalog database信息，主机名：端口号：catalog数据库db_name
-user指定管理用户mysdbadmin
-sdb指定shard database name:sdb1
create shardcatalog-database sdb1:1521:shardcat -chunks 12 -user mysdbadmin/oracle -sdb shardcat-region region1,region2
----
GDSCTL>createshardcatalog -database sdb1:1521:shardcat -chunks 12 -user mysdbadmin/oracle-sdb shardcat -region region1,region2
Catalog is created
....
7.2.创建分片directory
GDSCTL> add gsm -gsmsharddirector1 -listener listener_port -pwd gsmcatuser_password
-catalog shard_catalog_host:1521:shardcat-region region1
GDSCTL> start gsm-gsm sharddirector1
------创建分片directory
--add gsm -gsmsharddirector1 -listener 1571 -pwd oracle -catalog sdb1:1521:shardcat -regionregion1
GDSCTL>add gsm -gsmsharddirector1 -listener 1571 -pwd oracle -catalog sdb1:1521:shardcat -regionregion1
GSM successfully added
GDSCTL>
GDSCTL>start gsm-gsm sharddirector1
GDSCTL>GSM isstarted successfully
--
Repeat steps 6 and 8 oneach shard director host. Replace the shard director name and region name withappropriate values for each host.
7.3.创建信用账户，该账户为操作系统账户，用于远程调用agent来进行后台job任务运行，例如dbca,netca等（默认使用oracle账户）
Using GDSCTL, set theoperating system credentials.
GDSCTL> addcredential -credential credential_name -osaccount os_account_name -ospasswordos_password
GDSCTL> exit
These credentials arethe operating system user name and password on the shard hosts (not the cataloghost), and the credentials are used by the remote scheduler agent to run jobson the hosts to set up the shards using DBCA, NETCA, and the like.
--add credential-credential shard_cred -osaccount oracle -ospassword oracle
GDSCTL>addcredential -credential shard_cred -osaccount oracle -ospassword oracle
The operation completedsuccessfully
GDSCTL>exit
8.发布系统管理的SDB
发布系统管理的SDB需要创建shardgroup和shard、创建配置用于shard分片的数据库、执行deloy、创建基于角色的全局服务等操作
系统管理的shard不需要用户映射数据到shard节点，数据使用分区技术自动hash分布到各个shard节点
使用以下命令验证是否可以可以shard数据库
SQL> setserveroutput on
SQL> executeDBMS_GSM_FIX.validateShard
8.1创建shardgroup
$ gdsctl
GDSCTL> set gsm -gsmsharddirector1
GDSCTL> connectmysdbadmin/oracle
i).创建主库的shardgroup
GDSCTL> add shardgroup-shardgroup primary_shardgroup -deploy_as primary -region region1
ii)创建ADG的shardgroup
GDSCTL> addshardgroup -shardgroup standby_shardgroup -deploy_as active_standby -regionregion2

8.4Deploy部署shard
此时，就开始部署shard了。在shard node上的agent会自动的调用netca和dbca，创建listener和database，2个shard node的操作是并行进行的。
（如果是有datauard，那么是先建立一对主备，再建立另一对主备。）你可以在分别是两个shard node上ps -ef|grep ora_ 看到已经有sh1和sh2的实例了。

8.7.Add aglobal service that runs on all of the primary shards.
添加服务
The oltp_rw_srvc globalservice is a global data service that a client can use to connect to thesharded database. The oltp_rw_srvc service runs the OLTP transactions on theprimary shards. Likewise, the oltp_ro_srvc global service is created to runread-only workload on the standby shards.

9.配置Shard应用
9.1.Connectto the shard catalog database, create the application schema user, and grantprivileges and roles to the user.
连接到catlog databse创建应用账号app_schema（SDB[shardcat实例]），并授权
In this example, theapplication schema user is called app_schema.
$ sqlplus / as sysdba
SQL> alter sessionenable shard ddl;
SQL> create userapp_schema identified by oracle;
SQL> grant allprivileges to app_schema;
SQL> grantgsmadmin_role to app_schema;
SQL> grantselect_catalog_role to app_schema;
SQL> grant connect,resource to app_schema;
SQL> grant dba toapp_schema;
SQL> grant executeon dbms_crypto to app_schema;
9.2.Createa tablespace set for the sharded tables.
使用app_schema登录创建表空间集
SQL> CREATETABLESPACE SET TSP_SET_1 using template (datafile size 100m autoextend on next10M
maxsize unlimited extent management localsegment space management auto);
Specifying theshardspace is optional when creating the tablespace set. If the shardspace isnot specified in the command, the default shardspace is used.

aler session enableshard ddl;
create tablespace setts_set_1 using template(datafile size 100m autoextend on next 10m maxsizeunlimited extent management local segment space management auto);
------创建表空间集

Tablespace created.
-----创建表空间
CREATE TABLESPACEproducts_tsp datafile size 100m autoextend on next 10M maxsize unlimited extentmanagement local uniform size 1m;
9.3Create asharded table for the root table.
创建分片表
In this example, theroot table is the Customers table in the sample Customers-Orders-Productsschema.
SQL> CONNECT app_schema/app_schema_password
SQL> ALTER SESSIONENABLE SHARD DDL;
SQL> CREATE SHARDEDTABLE Customers

9.5登录shardcat数据库验证创建的表空间集以及chunks数量
The number oftablespaces in the tablespace set is based on the number of chunks youspecified in the create shardcatalog command.
The tablespace set withthe first 6 chunks of the 12 that were specified in the shard catalog creationexample, and the duplicated Products tablespace is shown in the followingexample.
