本次使用三臺(tái)虛擬機(jī)進(jìn)行安裝：
其中：
(1) db01 主機(jī)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(huán)境變量需要手動(dòng)切換) ；
(2)db02 主機(jī)上安裝Shard1 ，也就是ORACLE 12.2 RDBMS ，不需要?jiǎng)?chuàng)建數(shù)據(jù)庫(kù)；
(3) db03 主機(jī)上安裝Shard2 ，也就是ORACLE 12.2 RDBMS ，不需要?jiǎng)?chuàng)建數(shù)據(jù)庫(kù)；

在Shard catalog 服務(wù)器gsm1 創(chuàng)建 non-cdb 數(shù)據(jù)庫(kù)。創(chuàng)建過(guò)程與普通數(shù)據(jù)庫(kù)相同。
三：配置GSM/Shard director
https://blogs.oracle.com/database4cn/12c-oracle-sharding
在db01 服務(wù)器(catalog 數(shù)據(jù)庫(kù)/shard director) ，連接到Sharding catalog 數(shù)據(jù)庫(kù), 解鎖 GSMCATUSER 用戶(hù)，shard director 通過(guò)GSMCATUSER 用戶(hù)連接到shard catalog database
SQL> alter user gsmcatuser identified by oracle account unlock;
在 catalog 數(shù)據(jù)庫(kù)，創(chuàng)建管理用戶(hù)mygds ，用戶(hù)mygds 用于存儲(chǔ)Sharding 管理信息，GDSCTL 接口通過(guò)用戶(hù)mygds 連接到catalog 數(shù)據(jù)庫(kù)。
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;
在db01 服務(wù)器(catalog 數(shù)據(jù)庫(kù)/shard director) ，啟動(dòng)listener
在db01 服務(wù)器(catalog 數(shù)據(jù)庫(kù)/shard director) ，創(chuàng)建shard catalog ，在shard catalog 中配置remote scheduler agent.
參數(shù)含義：
-user : 指定管理用戶(hù)，在前面步驟中創(chuàng)建的catalog database 管理用戶(hù)mygds
-database : 指定catalog database 信息，catalog 數(shù)據(jù)庫(kù)的主機(jī)名: 監(jiān)聽(tīng)器port: catalog 數(shù)據(jù)庫(kù)db_name
-sdb : 指定sharded database name
-agent_port: 設(shè)置端口，用于shard 節(jié)點(diǎn)agent 連接到GSM
-agent_password: 設(shè)置密碼，用于shard 節(jié)點(diǎn)agent 連接到GSM
如果沒(méi)有指定- sharding 參數(shù)，默認(rèn)是創(chuàng)建system-managed (default) 類(lèi)型
