搭建准备 搭建实时主备集群前，需要完成主机和备机的IP、端口规划。 IP规划主机IP：192.168.1.30，备机IP：192.168.1.20，监视器IP：192.168.1.18 数据库规划数据库名 实例名 PORT_NUM MAL_INST_DW_PORT MAL_HOST MAL_PORT MAL_DW_PORT
DMDW GRP1_RT_01 5246 45101 192.168.1.30 55101 65101
DMDW GRP1_RT_03 5246 45121 192.168.1.20 55121 65121
主机备份使用dmrman工具完成主机数据库的完全备份，后续备机数据库还原是要用到。 ./dmrman CTLSTMT="BACKUP DATABASE '/dm8/data/DMDW/dm.ini' FULL TO BACKUP_FILE1 BACKUPSET '/dm8/backup/BACKUP_FILE_01'"
