都存放在 \$GPHOME/bin 目录下。GP 提供的命令可以实现如下的管理任务： 在多个主机上批量执行命令(gpssh) ● 初始化 GP 集群 (gpointsystem) 启动(gpstart)或关闭GP集群(gpstop) 从集群中隔离故障的 Host 主机 (gpstop --host) 扩展 Instance 以及在新节点间重新分布 Table(gpexpand) ● 监控和恢复失败的 CHECKPOINT 操作: $ psql postgres -c "CHECKPOINT" 4. 停止数据库： $ gpstop -f 5. 重新启动数据库： $ gpstart -a 注意：增加该参数的值可能需要更多的共享内存，需要注意操作系统参数方面内存相关的参数配置。 ## 客户端/服务端间的加密连接 GP 原生支持客户端与 Master 服务端之间的 SSL gp_resource_manager -v "group" 2、重启 GP 数据库： $ psql postgres -c "CHECKPOINT" $ gpstop -af $ gpstart -a 启用资源组之后，任何 ROLE 提交的事务都会经过该 ROLE 所属的资源组来执行，并受到该资源组的限制（并发事务数量、CPU 百分比和内存百分比）。类似的，外部组件的 CPU 和内存

Admin常用命令 ## 数据库启动：gpstart • 常用可选参数：-a:直接启动，不提示终端使用者输入确 -m: 只启动master实例，主要在故障处理时使用 -R: 进入限制模式，只有超级用户能访问，常用于系统维护 ## 数据库停止：gpstop: - 常用可选参数：-a：直接停止，不提示终端使用者输入确认 -m：只停止master实例，与gpstart -m对应使用 -M fast 当数据库出现异常，不能正常使用时，此时可以重启数据库 建议每次关闭数据库前，执行一次checkpoint，或者UTILITY进入到每一个实例，执行checkpoint; 数据库重启时，可以gpstart -R参数，让系统进入限制模式，限制普通用户登录，便于对系统进行诊断和维护 在某些极端情况下，数据库重启失败，可能原因是Persistent或Xlog有数据不一致，此时，请在Support说明
