# gpmagic 不得将代码用于任何商业目的 旨在分享----个人行为 作者: 陈淼 邮箱: [email protected] 使用备份恢复命令,请将 gpddlbackup gpddlrestore gpmcbackup gpmcrestore 四个文件直接拷贝到$GPHOME/bin/目录下,修改owner为gpadmin和mod为755: [gpadmin@mdw ~]$ cd $GPHOME/bin [gpadmin@mdw bin]$ chown gpadmin. gp{mc,ddl}* [gpadmin@mdw bin]$ chmod 755 gp{mc,ddl}* 使用说明可以参考命令的help信息和word文档 gpddlbackup已经经过较大范围验证,欢迎试用 使用跨集群数据传输命令,请将 gpdbtransfer 文件直接拷贝到$GPHOME/bin/目录下,修改owner为gpadmin和mod为755: [gpadmin@mdw ~]$ cd $GPHOME/bin [gpadmin@mdw bin]$ chown gpadmin. gpdbtransfer [gpadmin@mdw bin]$ chmod 755 gpdbtransfer 使用说明可以参考命令的help信息或readme目录中查看 gpdbcluster命令暂未经过大规模验证 建议慎重用于生产环境 目前已经强化了Standby激活的逻辑,如果无法判断Master的状态就不切换, 因为,如果gpactivatestandby命令本身也无法判断Master状态的话, 可能会出现Master和Standby都活着的冲突状态, 目前进行了进一步强化,常规的Master状态判断使用pg_sleep进行长时间保持, 如果第一次检测到异常,将会马上再进行3次简单测试,只有4次都异常才认为Master访问异常, 这一机制的完善主要用于避免可能出现检测SQL被误杀的情况, 对于出现连接数超过限制的情况,将认为数据库状态是正常的,不会予以切换
