1.4 操作系统规划Table 1-3 Server Configuration Checklist for Oracle Grid Infrastructure | Check | Task |
|---|
| Disk space allocated to the temporary file system | At least 1 GB of space in the temporary disk space (/tmp) directory. | | Swap space allocation relative to RAM | Between 4 GB and 16 GB: Equal to RAM More than 16 GB: 16 GB Note:
If you enable HugePages for your Linux servers, then you should deduct
the memory allocated to HugePages from the available RAM before
calculating swap space. | | HugePages memory allocation | Allocate memory to HugePages large enough
for the System Global Areas (SGA) of all databases planned to run on the
cluster, and to accommodate the System Global Area for the Grid
Infrastructure Management Repository. | | Mount point paths for the software binaries | Oracle recommends that you create an Optimal
Flexible Architecture configuration as described in the appendix
“Optimal Flexible Architecture” in Oracle Grid Infrastructure
Installation and Upgrade Guide for your platform. | | Ensure that the Oracle home (the Oracle home path you select for Oracle Database) uses only ASCII characters | The ASCII character restriction includes
installation owner user names, which are used as a default for some home
paths, as well as other directory names you may select for paths. | | Set locale (if needed) | Specify the language and the territory, or
locale, in which you want to use Oracle components. A locale is a
linguistic and cultural environment in which a system or program is
running. NLS (National Language Support) parameters determine the
locale-specific behavior on both servers and clients. The locale setting
of a component determines the language of the user interface of the
component, and the globalization behavior, such as date and number
formatting. | | Set Network Time Protocol for Cluster Time Synchronization | Oracle Clusterware requires the same time
zone environment variable setting on all cluster nodes.Ensure that you
set the time zone synchronization across all cluster nodes using either
an operating system configured network time protocol (NTP) or Oracle
Cluster Time Synchronization Service. | | Check Shared Memory File System Mount | By default, your operating system includes an entry in /etc/fstab to mount /dev/shm. However, if your Cluster Verification Utility (CVU) or Oracle Universal Installer (OUI) checks fail, then ensure that the /dev/shm mount area is of type tmpfs and is mounted with the following options:rw and exec permissions set on itWithout noexec or nosuid set on itNote:
Your operating system usually sets these options as the default
permissions. If they are set by the operating system, then they are not
listed on the mount options. |

the Unbreakable Linux Network, or configure a yum repository from the
Oracle Linux yum server website, and then install the Oracle
Preinstallation RPM. This RPM installs all required kernel packages for
Oracle Grid Infrastructure and Oracle Database installations, and
performs other system configuration.Supported distributions:Oracle Linux

known as KVM virtualization, is certified on Oracle Database 19c for all
supported Oracle Linux 7 distributions. For more information on
supported virtualization technologies for Oracle Database, refer to the
virtualization
matrix:https://www.oracle.com/database/technologies/virtualization-matrix.html |
1.5 共享存储规划able 1-6 Oracle Grid Infrastructure Storage Configuration Checks | Check | Task |
|---|
| Minimum disk space (local or shared) for Oracle Grid Infrastructure Software | At least 12 GB of space for the Oracle Grid
Infrastructure for a cluster home (Grid home). Oracle recommends that
you allocate 100 GB to allow additional space for patches. At least 10
GB for Oracle Database Enterprise Edition.Allocate additional storage
space as per your cluster configuration, as described in Oracle
Clusterware Storage Space Requirements. | | Select Oracle ASM Storage Options | During installation, based on the cluster
configuration, you are asked to provide Oracle ASM storage paths for the
Oracle Clusterware files. These path locations must be writable by the
Oracle Grid Infrastructure installation owner (Grid user). These
locations must be shared across all nodes of the cluster on Oracle ASM
because the files in the Oracle ASM disk group created during
installation must be available to all cluster member nodes.For Oracle
Standalone Cluster deployment, shared storage, either Oracle ASM or
shared file system, is locally mounted on each of the cluster nodes.For
Oracle Domain Services Cluster deployment, Oracle ASM storage is shared
across all nodes, and is available to Oracle Member Clusters. Oracle
Member Cluster for Oracle Databases can either use storage services from
the Oracle Domain Services Cluster or local Oracle ASM storage shared
across all the nodes. Oracle Member Cluster for Applications always use
storage services from the Oracle Domain Services Cluster. Before
installing Oracle Member Cluster, create a Member Cluster Manifest file
that specifies the storage details.Voting files are files that Oracle Clusterware uses to verify cluster node membership and status. Oracle Cluster Registry files (OCR) contain cluster and database configuration information for Oracle Clusterware. | | Select Grid Infrastructure Management Repository (GIMR) Storage Option | Depending on the type of cluster you are
installing, you can choose to either host the Grid Infrastructure
Management Repository (GIMR) for a cluster on the same cluster or on a
remote cluster.Note:Starting with Oracle Grid Infrastructure 19c,
configuring GIMR is optional for Oracle Standalone Cluster
deployments.For Oracle Standalone Cluster deployment, you can specify
the same or separate Oracle ASM disk group for the GIMR.For Oracle
Domain Services Cluster deployment, the GIMR must be configured on a
separate Oracle ASM disk group.Oracle Member Clusters use the remote
GIMR of the Oracle Domain Services Cluster. You must specify the GIMR
details when you create the Member Cluster Manifest file before
installation. |

4.3.4 调整network当使用Oracle集群的时候，Zero Configuration Network一样可能会导致节点间的通信问题，所以也应该停掉Without zeroconf, a network administrator must set up network services, such as Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS), or configure each computer's network settings manually.在使用平常的网络设置方式的情况下是可以停掉Zero Conf的

# Welcome textecho "This script is provided by Doc ID 401749.1 from My Oracle Support(http://support.oracle.com) where it is intended to compute values forthe recommended HugePages/HugeTLB configuration for the current sharedmemory segments on Oracle Linux. Before proceeding with the execution please note following: * For ASM instance, it needs to configure ASMM instead of AMM. * The 'pga_aggregate_target' is outside the SGA and you should accommodate this while calculating the overall size. * In case you changes the DB SGA size, as the new SGA will not fit in the previous HugePages configuration, it had better disable the whole HugePages, start the DB with new SGA size and run the script again.And make sure that: * Oracle Database instance(s) are up and running * Oracle Database 11g Automatic Memory Management (AMM) is not setup (See Doc ID 749851.1) * The shared memory segments can be listed by command: # ipcs -m

计算需要的页数：
linux 一个大页的大小为 2M，开启大页的总内存应该比 sga_max_size 稍稍大一点，比如
sga_max_size=3g，则：hugepages > (3*1024)/2 = 1536
配置 sysctl.conf 文件，添加：
[root@ node01 ~]$ vi /etc/sysctl.conf
vm.nr_hugepages = 1550
配置/etc/security/limits.conf，添加（比 sga_max_size 稍大，官方建议为总物理内存的 90%，以 K 为
单位）：
[root@ node01 ~]$ vi /etc/security/limits.conforacle soft memlock 3400000oracle hard memlock 3400000

4.16 配置NTP服务（可选）4.16.1 使用ctss各节点系统时间校对:--检验时间和时区确认正确date
--关闭chrony服务，移除chrony配置文件（后续使用ctss）systemctl list-unit-files|grep chronydsystemctl status chronyd
systemctl disable chronydsystemctl stop chronyd
mv /etc/chrony.conf /etc/chrony.conf_bakmv /etc/ntp.conf /etc/ntp.conf_baksystemctl list-unit-files|grep -E 'ntp|chrony'--这里实验环境，选择不使用NTP和chrony，这样Oracle会自动使用自己的ctss服务
4.16.2 使用ntp
1）修改所有节点的/etc/ntp.conf【命令】vi /etc/ntp.conf【内容】restrict 192.168.6.3 nomodify notrap nopeer noquery //当前节点IP地址restrict 192.168.6.2 mask 255.255.255.0 nomodify notrap //集群所在网段的网关（Gateway），子网掩码（Genmask）
2）选择一个主节点，修改其/etc/ntp.conf【命令】vi /etc/ntp.conf【内容】在server部分添加一下部分，并注释掉server 0 ~ n
server 127.127.1.0Fudge 127.127.1.0 stratum 10
3）主节点以外，继续修改/etc/ntp.conf【命令】vi /etc/ntp.conf【内容】在server部分添加如下语句，将server指向主节点。server 192.168.6.3Fudge 192.168.6.3 stratum 10

检查ntp配置文件/etc/sysconfig/ntpd，也已经从默认值OPTIONS="-g"修改成OPTIONS="-x -g"，但是在使用命令$ cluvfy comp clocksync -n all –verbose检查时为什么会失败呢？通过MOS文档《Linux:CVU NTP Prerequisite check fails with PRVF-7590, PRVG-1024 and PRVF-5415 (Doc ID2126223.1)》分析可以看出：If var/run/ntpd.pid does not existon the server, the CVU command fails. This is due to unpublished bug 19427746 which has been fixed in Oracle 12.2.（意思是：如果服务器上不存在/var/run/ntpd.pid，则CVU命令失败。这是由于未发布的错误BUG 19427746，该错误已在Oracle 12.2中修复。）

4.21 配置IO调度说明：# cat /sys/block/${ASM_DISK}/queue/schedulernoop [deadline] cfq
If the default disk I/O scheduler is not Deadline, then set it using a rules file:1. Using a text editor, create a UDEV rules file for the Oracle ASM devices:# vi /etc/udev/rules.d/60-oracle-schedulers.rules2. Add the following line to the rules file and save it:ACTION=="add|change", KERNEL=="sd[a-z]", ATTR{queue/rotational}=="0",ATTR{queue/scheduler}="deadline"3. On clustered systems, copy the rules file to all other nodes on the cluster. Forexample:$ scp 60-oracle-schedulers.rules root@node2:/etc/udev/rules.d/4. Load the rules file and restart the UDEV service. For example:a. Oracle Linux and Red Hat Enterprise Linux#udevadm control --reload-rules && udevadm trigger
操作：cat /etc/udev/rules.d/60-oracle-schedulers.rulesACTION=="add|change", KERNEL=="dm-[a-z]", ATTR{queue/rotational}=="0", ATTR{queue/scheduler}="deadline"udevadm control --reload-rules && udevadm trigger

Proceeding further...firsthost oracle19c-rac1numhosts 2The script will setup SSH connectivity from the host oracle19c-rac1 to allthe remote hosts. After the script is executed, the user can use SSH to runcommands on the remote hosts or copy files between this host oracle19c-rac1and the remote hosts without being prompted for passwords or confirmations.
NOTE 1:As part of the setup procedure, this script will use ssh and scp to copyfiles between the local host and the remote hosts. Since the script does notstore passwords, you may be prompted for the passwords during the execution ofthe script whenever ssh or scp is invoked.
NOTE 2:AS PER SSH REQUIREMENTS, THIS SCRIPT WILL SECURE THE USER HOME DIRECTORYAND THE .ssh DIRECTORY BY REVOKING GROUP AND WORLD WRITE PRIVILEGES TO THESEdirectories.
Do you want to continue and let the script make the above mentioned changes (yes/no)?yes
The user chose yesPlease specify if you want to specify a passphrase for the private key this script will create for the local host. Passphrase is used to encrypt the private key and makes SSH much more secure. Type 'yes' or 'no' and then press enter. In case you press 'yes', you would need to enter the passphrase whenever the script executes ssh or scp. noThe estimated number of times the user would be prompted for a passphrase is 4. In addition, if the private-public files are also newly created, the user would have to specify the passphrase on one additional occasion.Enter 'yes' or 'no'.yes

------------------------------------------------------------------------Verifying SSH setup===================The script will now run the date command on the remote nodes using sshto verify if ssh is setup correctly. IF THE SETUP IS CORRECTLY SETUP,THERE SHOULD BE NO OUTPUT OTHER THAN THE DATE AND SSH SHOULD NOT ASK FORPASSWORDS. If you see any output other than date or are prompted for thepassword, ssh is not setup correctly and you will need to resolve theissue and set up ssh again.The possible causes for failure could be:1. The server settings in /etc/ssh/sshd_config file do not allow sshfor user grid.2. The server may have disabled public key based authentication.3. The client public key on the server may be outdated.4. ~grid or ~grid/.ssh on the remote host may not be owned by grid.5. User may not have passed -shared option for shared remote users ormay be passing the -shared option for non-shared remote users.6. If there is output in addition to the date, but no password is asked,it may be a security alert shown as part of company policy.

5.5 安装前检查RHEL 7 系统不支持 AFD，在安装 GRID 时，必须去掉 Configure Oracle ASM Fileter Driver，否则报错。 19C 版本 GIMR 管理功能是一个可选项，不强制要求配置，建议不配置此功能(本例是启用了 GIMR)。 如果要配置 GIMR 功能，需要的容量不少于 35G，建议最小配置为 40G。最好 OCR 的磁盘组和 GIMR 的实例 ASM 存储分开，以便于对 OCR 磁盘组的管理 GRID 安装完成，在进行集群校验时，因为 SCAN NAME 没有使用 DNS 解析报失败，此情况正常，忽略
