Starting with Oracle Grid Infrastructure 12c Release 1 (12.1), as part of an Oracle Flex
Cluster installation, Oracle ASM is configured within Oracle Grid Infrastructure to
provide storage services
Starting with Oracle Grid Infrastructure 19c (19.3), with Oracle Standalone
Clusters, you can again place OCR and voting disk files directly on shared file
systems.
Oracle Flex Clusters
Starting with Oracle Grid Infrastructure 12c Release 2 (12.2), Oracle Grid
Infrastructure cluster configurations are Oracle Flex Clusters deployments.
从12.2 开始,集群分Standalone Cluster 与Domain Service Cluster 两种集群模式,
Standalone Cluster :
ü 可以支持64 个节点
ü 每个节点都直接连接共享存储
ü 各个节点共享存储都通过各自节点的ASM 实例或者共享文件系统挂载。
ü 本地控制GIMR
ü 19c Standalone Cluster 可选择是否配置GIMR
ü 可以使用GNS 配置vip 与scan ,也可以自己手工配置。
Domain Services Cluster :
ü 一个或多个节点组成域服务集群( DSC )
ü 一个或多个节点组成数据库成员集群( Database Member Cluster )
ü (可选)一个或多个节点组成应用成员节点( Application Member Cluster )
ü 集中的网格基础架构管理存储库(为 Oracle Cluster Domain 中的每个集群提供 MGMTDB )
ü 跟踪文件分析器( TFA )服务,用于 Oracle Clusterware 和 Oracle 数据库的目标诊断数据收集
ü 合并 Oracle ASM 存储管理服务
ü 可选的快速家庭配置( RHP )服务,用于安装群集,以及配置,修补和升级 Oracle Grid Infrastructure 和 Oracle Database 家庭。 配置 Oracle 域服务群集时,还可以选择配置 Rapid Home Provisioning Server 。
这些中心化的服务可以被 cluster Domain 中的数据库成员集群利用( Datebase Member Cluster 或 Application Member Cluster )。
Domain Service Cluster 中的存储访问:
DSC 中的 ASM 能够提供中心化的存储管理服务,成员集群( Member Cluster )能够通过以下两种方式访问 DSC 上的分片式存储:
ü 直接物理连接到分片存储进行访问
ü 使用 ASM IO Service 通过网络路径进行访问
单个Member Cluster 中所有节点必须以相同的方式访问分片存储,一个Domain Service Cluster 可以有多个Member Cluster ,架构图如下:

如果使用Oracle Linux ,可以通过Preinstallation RPM 配置操作系统, 如果安装Oracle Domain Services Cluster ,则需要配置GIMR ,则需要考虑大页面会被GIMR 的SGA 使用1G ,需要将此考虑到hugepages 中,standalone 则可以选择是否配置GIMR 。
# 查看透明大页面是否开启
[root@db-oracle-node1 ~]# cat /sys/kernel/mm/transparent_hugepage/enabled
[always] madvise never
# 查看透明大页面整理碎片功能是否开启, THP defragmentation
[root@db-oracle-node1 ~]# cat /sys/kernel/mm/transparent_hugepage/defrag
[always] madvise never
将"transparent_hugepage=never" 内核参数追加到GRUB_CMDLINE_LINUX 选项后:
# vi /etc/default/grub
GRUB_CMDLINE_LINUX="rd.lvm.lv=rhel/root rd.lvm.lv=rhel/swap ...
transparent_hugepage=never"
备份/boot/grub2/grub.cfg ,通过grub2-mkconfig -o 命令重建/boot/grub2/grub.cfg 文件:
On BIOS-based machines: ~]# grub2-mkconfig -o /boot/grub2/grub.cfg
On UEFI-based machines: ~]# grub2-mkconfig -o /boot/efi/EFI/redhat/grub.cfg
重启系统:
# shutdown -r now
验证参数设置是否正确:
# cat /proc/cmdline
注:如果还没有关闭THP ,参考 http://blog.itpub.net/31439444/viewspace-2674001/ 完成剩余步骤。

可以选择是否安装附加驱动与软件包,可以配置:PAM 、OCFS2 ,ODBC 、LDAP
如果是Oracle Linux, or Red Hat Enterprise Linux
可以使用 preinstall rpm 配置 os :
# cd /etc/yum.repos.d/
# wget http://yum.oracle.com/public-yum-ol7.repo
# yum repolist
# yum install oracle-database-preinstall-19c
也可以手工下载 preinstall rpm 安装包:
http://yum.oracle.com/repo/OracleLinux/OL6/latest/x86_64//
http://yum.oracle.com/repo/OracleLinux/OL7/latest/x86_64
preinstall 做以下工作:
ü 创建 oracle 用户,创建 oraInventory(oinstall) 以及 OSDBA(dba) 组。
ü 设置 sysctl.conf ,调整 Oracle 建议的系统启动参数、驱动参数
ü 设置 hard 以及 soft 用户资源限制。
ü 设置其他与系统内核版本相关的建议参数。
ü 设置 numa=off
如果不使用 preinstall rpm 配置内核参数,也可以手工配置 kernel parameter :
# vi /etc/sysctl.d/97-oracledatabase-
sysctl.conf
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 4294967295
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
改变当前系统值:
# /sbin/sysctl –system
# /sbin/sysctl -a
设置网络端口范围:
$ cat /proc/sys/net/ipv4/ip_local_port_range
# echo 9000 65500 > /proc/sys/net/ipv4/ip_local_port_range
# /etc/rc.d/init.d/network restart
如果不使用Oracle Preinstallation RPM ,可以使用Cluster Verification Utility, 按照下面步骤安装CVU :
ü Locate the cvuqdisk RPM package, which is located in the directory
Grid_home/cv/rpm. Where Grid_home is the Oracle Grid Infrastructure home
directory.
ü Copy the cvuqdisk package to each node on the cluster. You should ensure that
each node is running the same version of Linux.
ü Log in as root.
ü Use the following command to find if you have an existing version of the cvuqdisk
package:
# rpm -qi cvuqdisk
ü If you have an existing version of cvuqdisk, then enter the following command to
deinstall the existing version:
# rpm -e cvuqdisk
ü Set the environment variable CVUQDISK_GRP to point to the group that owns
cvuqdisk, typically oinstall. For example:
# CVUQDISK_GRP=oinstall; export CVUQDISK_GRP
ü In the directory where you have saved the cvuqdisk RPM, use the command rpm
-iv package to install the cvuqdisk package. For example:
# rpm -iv cvuqdisk-1.0.10-1.rpm
ü 运行安装验证
$ ./runcluvfy.sh stage -pre crsinst -fixup -n node1,node2,node3
网络配置说明:
( 1 )要么全部 ipv4 ,要么全部 ipv6 , GNS 可以生成 ipv6 地址
( 2 ) VIP , Starting with Oracle Grid Infrastructure 18c, using VIP is optional for Oracle
Clusterware deployments. You can specify VIPs for all or none of the cluster
nodes. However, specifying VIPs for selected cluster nodes is not supported.
( 3) Private:安装过程可以配置四个 interface private IP做为 HAIP(高可用 IP),如果配置了超过四个 interface,则超过四个的部分自动做为冗余, private可以不使用 bond网卡绑定,集群可以自动高可用。
( 4 ) Public/VIP 名称:可以使用字母数字以及“ -”连接符,不允许使用“ _“下划线
( 5 ) Public/VIP/SCAN VIP 需要在同一个子网段。
( 6 ) Public 需要固定配置在各个节点网卡, VIP 、 Private IP 、 SCAN 都可以交给 GNS 来配置,除了 SCAN 需要三个固定 IP 以外,其他都需要一个固定 IP ,可以不固定在网卡,但是要固定解析。
只通过DNS 解析SCAN ,Public/Private/VIP 均通过手工配置固定IP ,安装时手工指定设置。
要启用GNS,需要使用dhcp+DNS配置,DNS正反解析无需解析vip以及scan,只需要vip与scan的域名在交给gns管理的子域里即可。

保证所有节点使用NTP或者CTSS同步时间。
安装之前,保证各个节点时钟相同,如果使用 CTSS ,可以通过下面步骤关闭 linux 7 自带 NTP :
By default, the NTP service available on Oracle Linux 7 and Red Hat
Linux 7 is chronyd.
Deactivating the chronyd Service
To deactivate the chronyd service, you must stop the existing chronyd service, and
disable it from the initialization sequences.
Complete this step on Oracle Linux 7 and Red Hat Linux 7:
1. Run the following commands as the root user:
# systemctl stop chronyd
# systemctl disable chronyd
Confirming Oracle Cluster Time Synchronization Service After Installation
To confirm that ctssd is active after installation, enter the following command as the
Grid installation owner:
$ crsctl check ctss
如果使用NAS ,为了Oracle Clusterware 更好的容忍NAS 设备以及NAS 挂载的网络失败,建议开启Name Service Cache Daemon ( nscd) 。
# chkconfig --list nscd
# chkconfig --level 35 nscd on
# service nscd start
# service nscd restart
systemctl --all |grep nscd
For best performance for Oracle ASM, Oracle recommends that you use the Deadline
I/O Scheduler.
# cat /sys/block/${ASM_DISK}/queue/scheduler
noop [deadline] cfq
If the default disk I/O scheduler is not Deadline, then set it using a rules file:
1. Using a text editor, create a UDEV rules file for the Oracle ASM devices:
# vi /etc/udev/rules.d/60-oracle-schedulers.rules
2. Add the following line to the rules file and save it:
ACTION=="add|change", KERNEL=="sd[a-z]", ATTR{queue/rotational}=="0",
ATTR{queue/scheduler}="deadline"
3. On clustered systems, copy the rules file to all other nodes on the cluster. For
example:
$ scp 60-oracle-schedulers.rules root@node2:/etc/udev/rules.d/
4. Load the rules file and restart the UDEV service. For example:
Oracle Linux and Red Hat Enterprise Linux
# udevadm control --reload-rules
5. Verify that the disk I/O scheduler is set as Deadline.
# cat /sys/block/${ASM_DISK}/queue/scheduler
noop [deadline] cfq
为了防止某些情况下 ssh 失败,设置超时限制为 ulimit :
/etc/ssh/sshd_config on all cluster nodes:
# vi /etc/ssh/sshd_config
LoginGraceTime 0
判断是否有inventory 以及组是否之前存在:
# more /etc/oraInst.loc
$ grep oinstall /etc/group
创建 inventory 目录,不要指定到 oracle base 目录下,防止发生安装过程中权限改变导致安装错误。
所有节点 user 以及 group 的 id 必须相同。
# groupadd -g 54421 oinstall
# groupadd -g 54322 dba
# groupadd -g 54323 oper
# groupadd -g 54324 backupdba
# groupadd -g 54325 dgdba
# groupadd -g 54326 kmdba
# groupadd -g 54327 asmdba
# groupadd -g 54328 asmoper
# groupadd -g 54329 asmadmin
# groupadd -g 54330 racdba
# /usr/sbin/useradd -u 54321 -g oinstall -G dba,asmdba,backupdba,dgdba,kmdba,oper,racdba oracle
# useradd -u 54322 -g oinstall -G asmadmin,asmdba,racdba grid
# id oracle
# id grid
# passwd oracle
# passwd grid
建议使用 OFA 目录结构 , 保证 Oracle home 目录路径只包含 ASCII 码字符。
GRID standalone 可以将 grid 安装在 oracle database 软件的 ORACLE_BASE 目录下,其他不可以。
# mkdir -p /u01/app/19.0.0/grid
# mkdir -p /u01/app/grid
# mkdir -p /u01/app/oracle/product/19.0.0/dbhome_1/
# chown -R grid:oinstall /u01
# chown oracle:oinstall /u01/app/oracle
# chmod -R 775 /u01/

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib
$ . ./.bash_profile
$ xhost + hostname
$ export DISPLAY=local_host:0.0
preinstall rpm 包只配置 oracle 用户,安装 GI ,复制 oracle 设置,改为 grid 用户:
以下oracle grid用户都需要检查:
file descriptor :
$ ulimit -Sn
$ ulimit -Hn
number of processes :
$ ulimit -Su
$ ulimit -Hu
stack :
$ ulimit -Ss
$ ulimit -Hs
为了确保不会因为 X11 转发导致安装失败, oracle grid 用户家目录下 .ssh:
$ ~/.ssh/config
Host *
ForwardX11 no
如果使用 DNFS ,则可以参考文档配置 DNFS 。
如果要创建 Oracle Member Cluster ,则需要在Oracle Domain Services Cluster 上创建Member Cluster Manifest File ,参照官方文档Oracle Grid Infrastructure Grid Infrastructure Installation and Upgrade Guide 下面章节:

图形界面进行到创建OCR ASM磁盘组时,无法发现ASM磁盘,检查UDEV,UDEV配置正确,检查cfgtoollogs日志发现如下报错:

发现 ASM 磁盘路径报错:
INFO: [Mar 9, 2020 1:15:03 PM] Executing [/u01/app/19.0.0/grid/bin/kfod.bin, nohdr=true, verbose=true, disks=all, status=true, op=disks, asm_diskstring='/dev/asm*']

解决:
将报错前命令单独拿出来执行
/u01/app/19.0.0/grid/bin/kfod.bin nohdr=true, verbose=true, disks=all, status=true, op=disks, asm_diskstring='/dev/asm*'
发现报错 NLS DATA 错误,很明显,跟 .bash_profile 环境配置文件设置的 NLS 相关变量有关,注释掉相关 NLS_LANG 变量,生效,再次执行,一切正常。

遇到问题:
CRS-5017: The resource action "ora.czhl.db start" encountered the following error:
ORA-12547: TNS:lost contact
. For details refer to "(:CLSN00107:)" in "/u01/app/grid/diag/crs/pub19-node2/crs/trace/crsd_oraagent_oracle.trc".
解决:
节点 2 ORACLE_HOME 目录有两层权限不正确,修改权限之后,手工启动数据库正常。
[root@pub19-node2 oracle]# chown oracle:oinstall product/

$ unzip unzip p30464035_190000_Linux-x86-64.zip
oracle 用户(两节点都要升级):
# su - oracle

/* 检查补丁版本,其实只给 1 节点 GI 打了补丁,继续给节点 2GI ,节点 1 DB ,节点 2 DB 打补丁,一定要注意 opatchauto , GI 打补丁需要用 GI ORACLE_HOME 下 opatchauto , DB 打补丁需要 DB ORACLE_HOME 下 opatchauto
节点 1 :
# /u01/app/19.0.0/grid/OPatch/opatchauto apply -oh /u01/app/19.0.0/grid /software/30464035/
节点 2 :
# /u01/app/19.0.0/grid/OPatch/opatchauto apply -oh /u01/app/19.0.0/grid /software/30464035/
节点 1 :
# /u01/app/oracle/product/19.0.0/dbhome_1/OPatch/opatchauto apply /software/30464035/ -oh /u01/app/19.0.0/grid,/u01/app/oracle/product/19.0.0/dbhome_1
节点 2 :
# ls -l /u01/app/oraInventory/ContentsXML/oui-patch.xml # 一定要检查此文件此时权限,否则报下面错误,导致补丁 corrupt ,且无法回退跟再次正向应用,修改权限,打补丁,如果报错,可采用 opatchauto resume 命令,继续应用补丁即可。
# /u01/app/oracle/product/19.0.0/dbhome_1/OPatch/opatchauto apply /software/30464035/ -oh /u01/app/oracle/product/19.0.0/dbhome_1
Caution :
[Mar 11, 2020 8:56:05 PM] [WARNING] OUI-67124:ApplySession failed in system modification phase... 'ApplySession::apply failed: java.io.IOException: oracle.sysman.oui.patch.PatchException: java.io.FileNotFoundException: /u01/app/oraInventory/ContentsXML/oui-patch.xml (Permission denied)'
解决:
/* 按照日志输出,赋权
# chmod 664 /u01/app/oraInventory/ContentsXML/oui-patch.xml
# /u01/app/oracle/product/19.0.0/dbhome_1/OPatch/opatchauto resume /software/30464035/ -oh /u01/app/oracle/product/19.0.0/dbhome_1
如果按照日志提示恢复,则可以采取如下步骤来解决打补丁问题:
/* 执行 restore.sh ,最后还是失败,所以只能采取手工复制软件,加回滚的办法
# /u01/app/oracle/product/19.0.0/dbhome_1/OPatch/opatchauto rollback /software/30464035/ -oh /u01/app/oracle/product/19.0.0/dbhome_1
/* 按照失败提示,哪些文件不存在,将对应补丁解压文件夹中拷贝到 ORACLE_HOME 指定目录中,继续回滚,直到成功回滚。
再次给节点2 oracle软件打补丁:
# /u01/app/oracle/product/19.0.0/dbhome_1/OPatch/opatchauto apply /software/30464035/ -oh /u01/app/19.0.0/grid,/u01/app/oracle/product/19.0.0/dbhome_1
验证补丁:

$ /u01/app/oracle/product/19.0.0/dbhome_1/OPatch/opatch lsinv
