DM7如何使用DMASM安装DMRAC

小编给大家分享一下DM7如何使用DMASM安装DMRAC，希望大家阅读完这篇文章之后都有所收获，下面让我们一起去探讨吧！

一.环境准备
主机 IP地址(对外服务) IP地址(内部通信) 实例名 操作系统
dmrac1 10.18.13.161 10.10.10.161 rac0 Redhat 6.7
dmrac2 10.18.13.162 10.10.10.162 rac1 Redhat 6.7

共享存储
/dev/sdb /dev/raw/raw1 dcr disk 2G
/dev/sdc /dev/raw/raw2 voting disk 2G
/dev/sdd /dev/raw/raw3 log disk 10G
/dev/sde /dev/raw/raw4 data disk1 10G
/dev/sdf /dev/raw/raw5 data disk2 10G

二、操作系统配置

1、关闭防火墙和SELINUX

[root@cs ~]# service iptables stopiptables: Setting chains to policy ACCEPT: nat mangle filter [ OK ]iptables: Flushing firewall rules: [ OK ]iptables: Unloading modules: [ OK ][root@cs ~]# chkconfig iptables off[root@cs ~]# setenforce 0[root@cs ~]# sed -i s:^SELINUX=.*$:SELINUX=disabled:g /etc/selinux/config[root@cs ~]# service iptables stopiptables: Setting chains to policy ACCEPT: nat mangle filter [ OK ]iptables: Flushing firewall rules: [ OK ]iptables: Unloading modules: [ OK ][root@cs ~]# chkconfig iptables off[root@cs ~]# setenforce 0[root@cs ~]# sed -i s:^SELINUX=.*$:SELINUX=disabled:g /etc/selinux/config

2、修改主机名

[root@cs ~]# hostname dmrac1[root@cs ~]# hostname dmrac2[root@cs ~]# sed -i s:^HOSTNAME=.*$:HOSTNAME=dmrac1:g /etc/sysconfig/network[root@cs ~]# sed -i s:^HOSTNAME=.*$:HOSTNAME=dmrac2:g /etc/sysconfig/network

3、修改hosts文件

[root@cs ~]# echo "> 10.18.13.161 dmrac1> 10.18.13.162 dmrac2" >> /etc/hosts[root@cs ~]# echo "> 10.18.13.161 dmrac1> 10.18.13.162 dmrac2" >> /etc/hosts

三、 安装达梦软件
为了减少对操作系统的影响，用户不应该以root系统用户来安装和运行DM。用户可以在安装之前为DM创建一个专用的系统用户。具体操作详见 Oracle Linux 7.1中安装达梦数据库DM7

四、绑定UDEV

[root@dmrac1 rules.d]# vi 99-dm-devices.rulesACTION=="add", KERNEL=="sdb", RUN+="/bin/raw /dev/raw/raw1 %N"ACTION=="add", KERNEL=="sdc", RUN+="/bin/raw /dev/raw/raw2 %N"ACTION=="add", KERNEL=="sdd", RUN+="/bin/raw /dev/raw/raw3 %N"ACTION=="add", KERNEL=="sde", RUN+="/bin/raw /dev/raw/raw4 %N"ACTION=="add", KERNEL=="sdf", RUN+="/bin/raw /dev/raw/raw5 %N"ACTION=="add", KERNEL=="raw[1-5]", OWNER="dmdba", GROUP="dinstall", MODE="660"~[root@dmrac1 rules.d]# start_udevStarting udev: [ OK ][root@dmrac1 rules.d]# ls -lrt /dev/raw/total 0crw-rw----. 1 root disk 162, 0 Apr 24 14:08 rawctlcrw-rw----. 1 dmdba dinstall 162, 2 Apr 24 14:08 raw2crw-rw----. 1 dmdba dinstall 162, 1 Apr 24 14:08 raw1crw-rw----. 1 dmdba dinstall 162, 4 Apr 24 14:08 raw4crw-rw----. 1 dmdba dinstall 162, 3 Apr 24 14:08 raw3crw-rw----. 1 dmdba dinstall 162, 5 Apr 24 14:08 raw5[root@dmrac2 rules.d]# vi 99-dm-devices.rulesACTION=="add", KERNEL=="sdb", RUN+="/bin/raw /dev/raw/raw1 %N"ACTION=="add", KERNEL=="sdc", RUN+="/bin/raw /dev/raw/raw2 %N"ACTION=="add", KERNEL=="sdd", RUN+="/bin/raw /dev/raw/raw3 %N"ACTION=="add", KERNEL=="sde", RUN+="/bin/raw /dev/raw/raw4 %N"ACTION=="add", KERNEL=="sdf", RUN+="/bin/raw /dev/raw/raw5 %N"ACTION=="add", KERNEL=="raw[1-5]", OWNER="dmdba", GROUP="dinstall", MODE="660"~[root@dmrac2 rules.d]# start_udevStarting udev: [ OK ][root@dmrac2 rules.d]# ls -lrt /dev/raw/total 0crw-rw----. 1 root disk 162, 0 Apr 24 14:08 rawctlcrw-rw----. 1 dmdba dinstall 162, 2 Apr 24 14:08 raw2crw-rw----. 1 dmdba dinstall 162, 1 Apr 24 14:08 raw1crw-rw----. 1 dmdba dinstall 162, 4 Apr 24 14:08 raw4crw-rw----. 1 dmdba dinstall 162, 3 Apr 24 14:08 raw3crw-rw----. 1 dmdba dinstall 162, 5 Apr 24 14:08 raw5

可以通过blockdev --getsize64 /dev/raw/raw1命令查看裸设备大小

[root@dmrac1 rules.d]# blockdev --getsize64 /dev/raw/raw12147483648[root@dmrac1 rules.d]# blockdev --getsize64 /dev/raw/raw22147483648[root@dmrac1 rules.d]# blockdev --getsize64 /dev/raw/raw310737418240[root@dmrac1 rules.d]# blockdev --getsize64 /dev/raw/raw410737418240[root@dmrac1 rules.d]# blockdev --getsize64 /dev/raw/raw510737418240[root@dmrac2 rules.d]# blockdev --getsize64 /dev/raw/raw12147483648[root@dmrac2 rules.d]# blockdev --getsize64 /dev/raw/raw22147483648[root@dmrac2 rules.d]# blockdev --getsize64 /dev/raw/raw310737418240[root@dmrac2 rules.d]# blockdev --getsize64 /dev/raw/raw410737418240[root@dmrac2 rules.d]# blockdev --getsize64 /dev/raw/raw510737418240

六、配置dmdcr_cfg.ini文件
在2个节点的/dm7/data目录下创建配置文件dmdcr_cfg.ini，在文件中添加如下内容：

[root@dmrac1 /]# su - dmdba[dmdba@dmrac1 ~]$ mkdir /dm7/data[dmdba@dmrac1 ~]$cd /dm7/data[dmdba@dmrac1 data]$ cat dmdcr_cfg.iniDCR_N_GRP = 3DCR_VTD_PATH = /dev/raw/raw2DCR_OGUID = 63635[GRP]DCR_GRP_TYPE = CSSDCR_GRP_NAME = GRP_CSSDCR_GRP_N_EP = 2DCR_GRP_DSKCHK_CNT = 60[GRP_CSS]DCR_EP_NAME = CSS0DCR_EP_HOST = 10.10.10.161DCR_EP_PORT = 9541[GRP_CSS]DCR_EP_NAME = CSS1DCR_EP_HOST = 10.10.10.162DCR_EP_PORT = 9542[GRP]DCR_GRP_TYPE = ASMDCR_GRP_NAME = GRP_ASMDCR_GRP_N_EP = 2DCR_GRP_DSKCHK_CNT = 60[GRP_ASM]DCR_EP_NAME = ASM0DCR_EP_SHM_KEY = 93360DCR_EP_SHM_SIZE = 10DCR_EP_HOST = 10.18.13.161DCR_EP_PORT = 9641DCR_EP_ASM_LOAD_PATH = /dev/raw[GRP_ASM]DCR_EP_NAME = ASM1DCR_EP_SHM_KEY = 93361DCR_EP_SHM_SIZE = 10DCR_EP_HOST = 10.18.13.162DCR_EP_PORT = 9642DCR_EP_ASM_LOAD_PATH = /dev/raw[GRP]DCR_GRP_TYPE = DBDCR_GRP_NAME = GRP_RACDCR_GRP_N_EP = 2DCR_GRP_DSKCHK_CNT = 60[GRP_RAC]DCR_EP_NAME = RAC0DCR_EP_SEQNO = 0DCR_EP_PORT = 5236DCR_CHECK_PORT = 9741[GRP_RAC]DCR_EP_NAME = RAC1DCR_EP_SEQNO = 1DCR_EP_PORT = 5236DCR_CHECK_PORT = 9742[root@dmrac2 /]# su - dmdba[dmdba@dmrac2 ~]$ mkdir /dm7/data[dmdba@dmrac2 ~]$cd /dm7/data[dmdba@dmrac2 data]$ cat dmdcr_cfg.iniDCR_N_GRP = 3DCR_VTD_PATH = /dev/raw/raw2DCR_OGUID = 63635[GRP]DCR_GRP_TYPE = CSSDCR_GRP_NAME = GRP_CSSDCR_GRP_N_EP = 2DCR_GRP_DSKCHK_CNT = 60[GRP_CSS]DCR_EP_NAME = CSS0DCR_EP_HOST = 10.10.10.161DCR_EP_PORT = 9541[GRP_CSS]DCR_EP_NAME = CSS1DCR_EP_HOST = 10.10.10.162DCR_EP_PORT = 9542[GRP]DCR_GRP_TYPE = ASMDCR_GRP_NAME = GRP_ASMDCR_GRP_N_EP = 2DCR_GRP_DSKCHK_CNT = 60[GRP_ASM]DCR_EP_NAME = ASM0DCR_EP_SHM_KEY = 93360DCR_EP_SHM_SIZE = 10DCR_EP_HOST = 10.18.13.161DCR_EP_PORT = 9641DCR_EP_ASM_LOAD_PATH = /dev/raw[GRP_ASM]DCR_EP_NAME = ASM1DCR_EP_SHM_KEY = 93361DCR_EP_SHM_SIZE = 10DCR_EP_HOST = 10.18.13.162DCR_EP_PORT = 9642DCR_EP_ASM_LOAD_PATH = /dev/raw[GRP]DCR_GRP_TYPE = DBDCR_GRP_NAME = GRP_RACDCR_GRP_N_EP = 2DCR_GRP_DSKCHK_CNT = 60[GRP_RAC]DCR_EP_NAME = RAC0DCR_EP_SEQNO = 0DCR_EP_PORT = 5236DCR_CHECK_PORT = 9741[GRP_RAC]DCR_EP_NAME = RAC1DCR_EP_SEQNO = 1DCR_EP_PORT = 5236DCR_CHECK_PORT = 9742

七、使用 DMASMCMD 工具初始化（任意一节点执行）

[dmdba@dmrac1 data]$ dmasmcmdDMASMCMD V7.1.6.46-Build(2018.02.08-89107)ENTASM>create dcrdisk '/dev/raw/raw1' 'dcr'the ASM initialize dcrdisk /dev/raw/raw1 to name DMASMdcrUsed time: 9.322(ms).ASM>create votedisk '/dev/raw/raw2' 'vote'the ASM initialize votedisk /dev/raw/raw2 to name DMASMvoteUsed time: 6.251(ms).ASM>create asmdisk '/dev/raw/raw3' 'LOG0'the ASM initialize asmdisk /dev/raw/raw3 to name DMASMLOG0Used time: 8.825(ms).ASM>create asmdisk '/dev/raw/raw4' 'DATA0'the ASM initialize asmdisk /dev/raw/raw4 to name DMASMDATA0Used time: 6.145(ms).ASM>init dcrdisk '/dev/raw/raw1' from '/dm7/data/dmdcr_cfg.ini' identified by 'dameng123'[Trace]DG 126 allocate 4 extents for file 0xfe000002.Check dcr disk failed, please check and try againUsed time: 84.489(ms).提示检查dcr磁盘失败请再次执行ASM>init dcrdisk '/dev/raw/raw1' from '/dm7/data/dmdcr_cfg.ini' identified by 'dameng123'[Trace]DG 126 allocate 4 extents for file 0xfe000002.Used time: 00:00:06.078.ASM>init votedisk '/dev/raw/raw2' from '/dm7/data/dmdcr_cfg.ini'[Trace]DG 125 allocate 4 extents for file 0xfd000002.Used time: 36.305(ms).

八、准备DMASM 的 MAL 配置文件
在2个节点的/dm7/data目录下创建 DMASM 的 MAL 配置文件（命名为 dmasvrmal.ini），使用 DMASM 的所有节点都要配置，内容完全一样。

[dmdba@dmrac1 data]$ vi dmasvrmal.ini[MAL_INST1]MAL_INST_NAME = ASM0MAL_HOST = 10.10.10.161MAL_PORT = 7236[MAL_INST2]MAL_INST_NAME = ASM1MAL_HOST = 10.10.10.162MAL_PORT = 7237[dmdba@dmrac2 data]$ vi dmasvrmal.ini[MAL_INST1]MAL_INST_NAME = ASM0MAL_HOST = 10.10.10.161MAL_PORT = 7236[MAL_INST2]MAL_INST_NAME = ASM1MAL_HOST = 10.10.10.162MAL_PORT = 7237~

九、准备dmdcr.ini 配置文件
dmdcr.ini 是 dmcss、dmasmsvr、dmasmtool 工具的输入参数。记录了当前节点序列号以及 DCR 磁盘路径。
在2个节点的/dm/dmdbms/data目录下创建dmdcr.ini 配置文件，dmdcr_path 相同，dmasvrmal.ini 文件内容也相同，dmdcr_seqo 分别为 0 和 1。
节点 1：

[dmdba@dmrac1 data]$ vi dmdcr.iniDMDCR_PATH = /dev/raw/raw1DMDCR_MAL_PATH =/dm7/data/dmasvrmal.iniDMDCR_SEQNO = 0#ASMDMDCR_ASM_RESTART_INTERVAL = 0DMDCR_ASM_STARTUP_CMD = /dm7/bin/dmasmsvr dcr_ini=/dm7/data/dmdcr.ini#DBDMDCR_DB_RESTART_INTERVAL = 0DMDCR_DB_STARTUP_CMD = /dm7/bin/dmserver path=/dm7/data/rac0_config/dm.ini dcr_ini=/dm7/data/dmdcr.ini

节点2:

[dmdba@dmrac2 data]$ vi dmdcr.iniDMDCR_PATH = /dev/raw/raw1DMDCR_MAL_PATH =/dm7/data/dmasvrmal.iniDMDCR_SEQNO = 1#ASMDMDCR_ASM_RESTART_INTERVAL = 0DMDCR_ASM_STARTUP_CMD = /dm7/bin/dmasmsvr dcr_ini=/dm7/data/dmdcr.ini#DBDMDCR_DB_RESTART_INTERVAL = 0DMDCR_DB_STARTUP_CMD = /dm7/bin/dmserver path=/dm7/data/rac1_config/dm.ini dcr_ini=/dm7/data/dmdcr.ini

十、启动DMCSS、DMASM 服务程序
1、注册 DMCSS和DMASM服务
节点一:

[root@dmrac1 ~]# /dm7/script/root/dm_service_installer.sh -t dmcss -i /dm7/data/dmdcr.ini -p rac1Move the service script file(/dm7/bin/DmCSSServicerac1 to /etc/rc.d/init.d/DmCSSServicerac1)Finished to create the service (DmCSSServicerac1)[root@dmrac1 ~]# /dm7/script/root/dm_service_installer.sh -t dmasmsvr -i /dm7/data/dmdcr.ini -p rac1Move the service script file(/dm7/bin/DmASMSvrServicerac1 to /etc/rc.d/init.d/DmASMSvrServicerac1)Finished to create the service (DmASMSvrServicerac1)[root@dmrac1 ~]#

节点二:

[root@dmrac2 ~]# /dm7/script/root/dm_service_installer.sh -t dmcss -i /dm7/data/dmdcr.ini -p rac2Move the service script file(/dm7/bin/DmCSSServicerac2 to /etc/rc.d/init.d/DmCSSServicerac2)Finished to create the service (DmCSSServicerac2)[root@dmrac2 ~]# /dm7/script/root/dm_service_installer.sh -t dmasmsvr -i /dm7/data/dmdcr.ini -p rac2Move the service script file(/dm7/bin/DmASMSvrServicerac2 to /etc/rc.d/init.d/DmASMSvrServicerac2)Finished to create the service (DmASMSvrServicerac2)

2、启动DMCSS和DMASM服务
节点一：

[root@dmrac1 init.d]# service DmCSSServicerac1 startStarting DmCSSServicerac1: [ OK ][root@dmrac1 init.d]# service DmASMSvrServicerac1 startStarting DmASMSvrServicerac1: [ OK ]

节点二：

[root@dmrac2 init.d]# service DmCSSServicerac2 startStarting DmCSSServicerac2: [ OK ][root@dmrac2 init.d]# service DmASMSvrServicerac2 startStarting DmASMSvrServicerac2: [ OK ]

十一、创建DMASM磁盘组
在任意节点使用 dmasmtool 工具创建 DMASM 磁盘组。

[dmdba@dmrac1 ~]$ dmasmtool DCR_INI=/dm7/data/dmdcr.iniDMASMTOOL V7.1.6.46-Build(2018.02.08-89107)ENTASM>create diskgroup 'DMLOG' asmdisk '/dev/raw/raw3'Used time: 00:00:06.363.ASM>create diskgroup 'DMDATA' asmdisk '/dev/raw/raw4'Used time: 00:00:06.504.

十二、准备dminit.ini 配置文件
在2个节点的/dm/dmdbms/data目录下创建 dminit.ini 配置文件，添加如下内容。 在2个节点都创建。

[dmdba@dmrac1 data]$ vi dminit.inidb_name = racsystem_path = +DMDATA/datasystem = +DMDATA/data/rac/system.dbfsystem_size = 128roll = +DMDATA/data/rac/roll.dbfroll_size = 128main = +DMDATA/data/rac/main.dbfmain_size = 128ctl_path = +DMDATA/data/rac/dm.ctlctl_size = 8log_size = 256dcr_path = /dev/raw/raw1 #dcr 磁盘路径，目前不支持 asm，只能是裸设备dcr_seqno = 0auto_overwrite = 1[RAC0] #inst_name 跟 dmdcr_cfg.ini 中 DB 类型 group 中 DCR_EP_NAME 对应config_path = /dm7/data/rac0_configport_num = 5236mal_host = 10.10.10.161mal_port = 9340log_path = +DMLOG/log/rac0_log01.loglog_path = +DMLOG/log/rac0_log02.log[RAC1] #inst_name 跟 dmdcr_cfg.ini 中 DB 类型 group 中 DCR_EP_NAME 对应config_path = /dm7/data/rac1_configport_num = 5236mal_host = 10.10.10.162mal_port = 9341log_path = +DMLOG/log/rac1_log01.loglog_path = +DMLOG/log/rac1_log02.log[dmdba@dmrac2 data]$ vi dminit.inidb_name = racsystem_path = +DMDATA/datasystem = +DMDATA/data/rac/system.dbfsystem_size = 128roll = +DMDATA/data/rac/roll.dbfroll_size = 128main = +DMDATA/data/rac/main.dbfmain_size = 128ctl_path = +DMDATA/data/rac/dm.ctlctl_size = 8log_size = 256dcr_path = /dev/raw/raw1 #dcr 磁盘路径，目前不支持 asm，只能是裸设备dcr_seqno = 0auto_overwrite = 1[RAC0] #inst_name 跟 dmdcr_cfg.ini 中 DB 类型 group 中 DCR_EP_NAME 对应config_path = /dm7/data/rac0_configport_num = 5236mal_host = 10.10.10.161mal_port = 9340log_path = +DMLOG/log/rac0_log01.loglog_path = +DMLOG/log/rac0_log02.log[RAC1] #inst_name 跟 dmdcr_cfg.ini 中 DB 类型 group 中 DCR_EP_NAME 对应config_path = /dm7/data/rac1_configport_num = 5236mal_host = 10.10.10.162mal_port = 9341log_path = +DMLOG/log/rac1_log01.loglog_path = +DMLOG/log/rac1_log02.log

十三、使用dminit初始化数据库
在任意节点启动 dminit 工具初始化数据库。dminit 执行完成后，会在 config_path 目录（/dm7/data/rac0_config 和/dm7/data/rac1_config）下生成配置文件 dm.ini 和 dmmal.ini。

[dmdba@dmrac1 data]$ dminit control=/dm7/data/dminit.iniinitdb V7.1.6.46-Build(2018.02.08-89107)ENTdb version: 0x7000afile dm.key not found, use default license!License will expire on 2020-05-08log file path: +DMLOG/log/rac0_log01.loglog file path: +DMLOG/log/rac0_log02.loglog file path: +DMLOG/log/rac1_log01.loglog file path: +DMLOG/log/rac1_log02.logwrite to dir [+DMDATA/data/rac].create dm database success. 2020-04-24 16:39:03

将节点一的配置文件复制到节点二：

[dmdba@dmrac1 data]$ scp -r rac1_config 10.18.13.162:`pwd`The authenticity of host '10.18.13.162 (10.18.13.162)' can't be established.RSA key fingerprint is 89:fc:3e:e3:2d:27:94:07:0e:6b:fc:c5:e8:89:44:1f.Are you sure you want to continue connecting (yes/no)? yesWarning: Permanently added '10.18.13.162' (RSA) to the list of known hosts.dmdba@10.18.13.162's password:sqllog.ini 100% 479 0.5KB/s 00:00dm.ini 100% 40KB 39.8KB/s 00:00dmmal.ini 100% 204 0.2KB/s 00:00[dmdba@dmrac1 data]$

十四、启动数据库服务器
1、在2个节点分别注册DM 数据库服务：
节点一：

[root@dmrac1 init.d]# /dm7/script/root/dm_service_installer.sh -t dmserver -i /dm7/data/rac0_config/dm.ini -d /dm7/data/dmdcr.ini -p rac1Move the service script file(/dm7/bin/DmServicerac1 to /etc/rc.d/init.d/DmServicerac1)Finished to create the service (DmServicerac1)

节点二：

[root@dmrac2 ~]# /dm7/script/root/dm_service_installer.sh -t dmserver -i /dm7/data/rac1_config/dm.ini -d /dm7/data/dmdcr.ini -p rac2Move the service script file(/dm7/bin/DmServicerac2 to /etc/rc.d/init.d/DmServicerac2)Finished to create the service (DmServicerac2)

2、启动数据库

[root@dmrac1 init.d]# service DmServicerac1 startStarting DmServicerac1: [ OK ][root@dmrac2 ~]# service DmServicerac2 startStarting DmServicerac2: [ OK ]

手工启动命令如下，手工启动后窗口不能关闭，所以

./dmserver /dm7/data/rac0_config/dm.ini dcr_ini=/dm7/data/dmdcr.ini./dmserver /dm7/data/rac1_config/dm.ini dcr_ini=/dm7/data/dmdcr.ini

15 连接数据库验证
15.1 配置服务名文件

[dmdba@dmrac1 ~]$ vi /etc/dm_svc.confTIME_ZONE=(480)rac=(10.18.13.161:5236,10.18.13.162:5236)SWITCH_TIME=(10000)SWITCH_INTERVAL=(10)TIME_ZONE=(480)LANGUAGE=(en)[dmdba@dmrac2 ~]$ vi /etc/dm_svc.confTIME_ZONE=(480)rac=(10.18.13.161:5236,10.18.13.162:5236)SWITCH_TIME=(10000)SWITCH_INTERVAL=(10)TIME_ZONE=(480)LANGUAGE=(en)

15.2 连接RAC集群
节点一:

[dmdba@dmrac1 ~]$ disql SYSDBA/SYSDBA@rac
