解达梦数据库DPC集群的主要使用场景：
DMDPC 关注和解决的是大数据、计算与存储分离、高可用、支持全部的 SQL 标准、拥有完整的事务处理能力和集群规模能够动态伸缩的业务场景：
- 大量的复杂查询操作要求优化器能够生成优良的执行计划，并且执行引擎能够充分利用多机器、多核的硬件资源
- 某些行业对数据一致性和多副本备份容灾有较高要求，同时希望维护成本足够低和故障恢复时间足够短；
- 用户的业务规模有峰值，要求所需的机器资源能够灵活地添加和删除。
DPC架构：
一个完整的 DMDPC 架构由计划生成节点 SP、数据存储节点 BP 和元数据服务器节点 MP 三部分组成。
- SP 对外提供分布式数据库服务，用户可以登录到任意一个 SP 节点，获得完整的数据库服务，SP 节点不存储数据，配置成单机即可。
- BP 负责存储数据，执行 SP 的调度指令并将执行结果返回给 SP。
- MP 负责存储元数据并向 SP、BP 提供元数据服务。
MP 和 BP 节点既可以配置成单机，也可以配置成多副本系统。其中每一个多副本系统中只有一个作为主节点，其余节点均作为备份节点。
1 集群规划
DMDPC 集群规划部署 1 个 SP，2 个 BP 和 1 个 MP。
MP 采用单机模式，BP 采用多副本模式，每个 BP 配置 2 个副本。
集群规划示意：
2 初始化数据库实例
根据集群规划，初始化 8 个实例，分别为 SP、MP 和 6 个 BP 角色。

4 启动 MP
注意相关端口是否被占用，涉及相关的服务器，防火墙是否关闭或者是否将相关端口加入到白名单。
如果端口没被占用，持续报端口的错误，

[dmdba@localhost bin]$ 11 配置 BP dm.ini
RAFT_1 组各实例（BP11、BP12、BP13）和 RAFT_2 组各实例（BP21、BP22、BP23）中 dm.ini 文件的配置方法完全相同。
下面以 BP11 的 dm.ini 为例进行介绍。dm.ini 文件配置如下：
bash
ARCH_INI = 1 #打开归档配置
ALTER_MODE_STATUS = 0 #不允许用户直接通过SQL语句修改服务器模式12 配置 BP RAFT _1归档文件
修改 DMARCH.INI，配置 RAFT 归档与本地归档。RAFT_1 组配置如下：
1： 配置 BP11 归档文件 DMARCH.INI
bash
XMAL_HB_INTERVAL = 5 #节点通信检测间隔
