总共三个表，每个表36个chunks,chunk的个数是在create shardcatalog时指定的
验证chunk是否均匀分布
连接shard catalog数据库
[oracle@shardcat admin]$ sqlplus / as sysdba
SELECT a.name Shard, COUNT(b.chunk_number) Number_of_Chunks
FROM gsmadmin_internal.database a, gsmadmin_internal.chunk_loc b
WHERE a.database_num=b.database_num
GROUP BY a.name
ORDER BY a.name;
SHARD NUMBER_OF_CHUNKS
------------------------------ ----------------
sh1 18
sh2 18
每个表36个chunk，均匀分布在两个shard库上；这也表示一个shard库挂了，那么整个库也就挂了。

添加服务
The oltp_rw_srvc globalservice is a global data service that a client can use to connect to the sharded 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.

上一次连接GSM连接的分片是SH1，而这次连接的是SH2
在某个分片库上查询
上一步是在SH2上查询，本次在SH1上查询，预计应该有三条数据
[oracle@shard1 ~]$ sqlplus sharduser/sharduser
col custid for a12
col firstname for a12
col lastname for a12
select custid,firstname,lastname from customers;
CUSTID FIRSTNAME LASTNAME
------------ ------------ ------------
101 Pengfei Tan
102 aaaa bbbb
104 dddd bbbb
总共插入四条记录，三个在sh1上，一条在sh2上；通过gsm不指定条件连接则仅是查询某个分库片的数据。
