达梦守护集群部署安装

准备环境

主机：192.168.199.133 数据库已安装并开启归档

备机：192.168.199.134 数据库已安装并开启归档

数据库安装目录：/home/dmdba/dm/dmdbms

备份、归档、数据文件目录：/dm8/{dmbak,dmarch,dmdata}

主机全库备份

cd //home/dmdba/dm/dmdbms/bin

./dmrman

RMAN> backup database '/home/dmdba/dm/dmdbms/bin/dm.ini' full backupset '/dm8/dmbak/full01';

dmdba@localhost \~\]$ vim /dm8/dmdata/DAMENG/dmwatcher.ini \[GRP1

DW_TYPE = GLOBAL #全局守护类型

DW_MODE = MANUAL #MANUAL:故障手切 AUTO:故障自切

DW_ERROR_TIME = 20 #远程守护进程故障认定时间

INST_RECOVER_TIME = 60 #主库守护进程启动恢复的间隔时间

INST_OGUID = 45331 #守护系统唯一OGUID值

INST_INI = /dmdata/DAMENG/dm.ini

INST_AUTO_RESTART = 1 #打开实例自启功能

INST_STARTUP_CMD = /home/dmdba/dm/dmdbms/bin/DmServiceDMSERVER start #服务启动方式

RLOG_SEND_THRESHOLD = 0 #指定主库发送日志到备库的时间阈值，默认关闭

RLOG_APPLY_THRESHOLD = 0 #指定备库重演日志的时间阈值，默认关闭

拷贝备份文件

scp -r /dm8/dmbak/full01 dmdba@192.168.199.134:/dm8/dmbak

注册服务

cd /home/dmdba/dm/dmdbms/script/root

./dm_service_installer.sh -t dmwatcher -p Watcher -watcher_ini /dm8/dmdata/DAMENG/dmwatcher.ini

重启实例服务

cd /home/dmdba/dm/dmdbms/bin

./DmServiceDMSERVER restart

启动守护进程

./DmWatcherServiceWatcher start

配置备机dm.ini实例名

INSTANCE_NAME = DMSERVERB #实例名

编辑dmarch.ini

dmdba@localhost \~\]$ vim /dm8/dmdata/DAMENG/dmarch.ini \[ARCHIVE_LOCAL1

ARCH_TYPE = LOCAL

ARCH_DEST = /dm8/dmarch

ARCH_FILE_SIZE = 128

ARCH_SPACE_LIMIT = 1024

ARCHIVE_REALTIME1

ARCH_TYPE = REALTIME

ARCH_DEST = DMSERVER

复制主机dmmal.ini、dmwatcher.ini至备机

scp root@192.168.199.133:/dm8/dmdata/DAMENG/dmmal.ini /dm8/dmdata/DAMENG

注册服务

cd /home/dmdba/dm/dmdbms/script/root

./dm_service_installer.sh -t dmwatcher -p Watcher -watcher_ini /dm8/dmdata/DAMENG/dmwatcher.ini

重启实例服务

cd /home/dmdba/dm/dmdbms/bin

./DmServiceDMSERVER restart

./DmServiceDMSERVER stop

注：重启成功后需要停止服务，进行脱机数据恢复。

配置监视器

（1）非确认监视器：集群各节点bin目录中，存放非确认监视器配置文件。

（2）确认监视器：在仲裁机（非集群节点），存放确认监视器配置文件，并注册后台自启服务。

创建dmmonitor.ini

dmdba@localhost \~\]$ vim /home/dmdba/dm/dmdbms/bin/dmmonitor.ini MON_DW_CONFIRM = 0 #0:非确认（故障手切） 1:确认（故障自切） MON_LOG_PATH = ../log #监视器日志文件存放路径 MON_LOG_INTERVAL = 60 #每隔60s定时记录系统信息到日志文件 MON_LOG_FILE_SIZE = 512 #单个日志大小，单位MB MON_LOG_SPACE_LIMIT = 2048 #日志上限，单位MB \[GRP1

MON_INST_OGUID = 45331 #组GDW1的唯一OGUID值

MON_DW_IP = 192.168.199.133:5436 #IP对应MAL_HOST，PORT对应MAL_DW_PORT

MON_DW_IP = 192.168.199.134:5436

监视器的使用方法

|----------------------------|-----------------------|
| 命令 | 含义 |
| list | 查看守护进程的配置信息 |
| show global info | 查看所有实例组的信息 |
| tip | 查看系统当前运行状态 |
| login | 登录监视器 |
| logout | 退出登录 |
| choose switchover GDW1 | 主机正常：查看可切换为主机的实例列表 |
| switchover GDW1.实例名 | 主机正常：使用指定组的指定实例，切换为主机 |
| choose takeover GDW1 | 主机故障：查看可切换为主机的实例列表 |
| takeover GDW1.实例名 | 主机故障：使用指定组的指定实例，切换为主机 |
| choose takeover force GDW1 | 强制切换：查看可切换为主机的实例列表 |
| takeover force GDW1.实例名 | 强制切换：使用指定组的指定实例，切换为主机 |
| 主机故障后，在备机执行SELECT SF_DW_CHECK_TAKEOVER();【1:可接管 0:不可接管】 ||
