资源操作

ADD RESOURCE ds_0 (
HOST=127.0.0.1,
PORT=3306,
DB=ds_0,
USER=root,
PASSWORD=root
),ds_1 (
HOST=127.0.0.1,

规则操作

• 创建数据库发现规则

CREATE DB_DISCOVERY RULE ha_group_0 (
RESOURCES(ds_0, ds_1),
TYPE(NAME=mgr,PROPERTIES('group-name'='92504d5b-6dec')),
HEARTBEAT(PROPERTIES('keep-alive-cron'='0/5 * * * * ?'))
);

• 修改数据库发现规则

ALTER DB_DISCOVERY RULE ha_group_0 (
RESOURCES(ds_0, ds_1, ds_2),
TYPE(NAME=mgr,PROPERTIES('group-name'='92504d5b-6dec')),
HEARTBEAT(PROPERTIES('keep-alive-cron'='0/5 * * * * ?'))
);

• 删除数据库发现规则

DROP DB_DISCOVERY RULE ha_group_0;

• 删除数据库发现类型

DROP DB_DISCOVERY TYPE ha_group_0_mgr;

• 删除数据库发现心跳

DROP DB_DISCOVERY HEARTBEAT ha_group_0_heartbeat;

• 删除数据源

DROP RESOURCE ds_0,ds_1,ds_2;

• 删除分布式数据库

DROP DATABASE discovery_db;
