1. Oracle RAC安裝規劃
a) RAC物理架構圖
b) 軟件環境規劃
軟件：
GI 軟件：linuxx64_12201_grid_home.zip
DB 軟件：linuxx64_12201_database.zip
GI 補丁：p29301687_122010_Linux-x86-64.zip
DB 補丁：p29314339_122010_Linux-x86-64.zip
Opatch 補丁：p6880880_122010_Linux-x86-64.zip
rpm包：compat-libstdc++-33-3.2.3-69.el6.x86_64.rpm
數據庫版本：
12.2.0.1.19
操作系統：
64bit Redhat 7.3
c) 用戶組與文件系統規劃
用戶組和文件系統配置
軟件 用戶 主組 輔助組 ORACLE_BASE ORACLE_HOME
GI grid oinstall dba,asmadmin,asmdba,asmoper,racdba /oracle/app/grid /oracle/app/12.2.0/grid
DB oracle oinstall dba,oper,asmdba, asmadmin,racdba,backupdba,dgdba,kmdba /oracle/app/oracle $ORACLE_BASE/product/12.2.0/db_1
d) 網絡規劃
1. 優先雙網卡綁定原則
2. 優先私有網絡萬兆網卡原則
3. 避免使用169.254.*.* 地址原則
/etc/hosts列表如下
名稱 對應網卡 IP 用途
bmcdb1 bond0 10.151.115.71 public
bmcdb1-vip 10.151.115.73 VIP
bmcdb1-priv bond1 192.155.1.171 private
bmcdb2 bond0 10.151.115.72 public
bmcdb2-vip 10.151.115.74 VIP
bmcdb2-priv bond1 192.155.1.172 private
scan-bmcdb 10.151.115.75 scan-ip
e) 存儲規劃
1. 設置disk I/O schedulers為Deadline
# echo deadline > /sys/block/${ASM_DISK}/queue/scheduler
2. 綁定存儲LUN屬性,保證系統重啟屬性不變
3. ASM規劃表
ASM規劃表
磁盤組名 分區 屬主 權限 單個LUN大小 冗余 總容量
OCR emcpowera grid:asmadmin 660 18G
emcpowerb grid:asmadmin 660 18G Normal 54G
emcpowerc grid:asmadmin 660 18G
DATA emcpowere grid:asmadmin 660 200G External 200G
FRA emcpowerf grid:asmadmin 660 100G External 100G
OCR 磁盤組：保存CRS信息及Voting disk等信息
DATA磁盤組：保存數據文件、控制文件
FRA磁盤組：保存節點的歸檔文件
2. Oracle RAC所有集群節點準備
a) 硬件檢驗
1. 操作系統基礎環境檢驗
# 操作系統發行版
cat /etc/redhat-release
# 內核版本
uname -a
# Memory total
grep MemTotal /proc/meminfo
# SWAP Total
grep SwapTotal /proc/meminfo
# tmp目錄大小
df -h /tmp
# 當前內存和swap使用狀態
free -g
# 共享內存大小
df -h /dev/shm
# CPU 型號,物理個數,核數,邏輯個數
cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c
cat /proc/cpuinfo| grep "physical id"| sort| uniq| wc -l
cat /proc/cpuinfo| grep "cpu cores"| uniq
cat /proc/cpuinfo| grep "processor"| wc -l
# 節點信息收集省略
2. 雙網卡綁定
# 雙網卡綁定采用主備模式,雙節點保持Bond模式一置,并持續ping,拔物理線進行測試

2. 操作系統創建軟件安裝組及用戶(oracle,grid)
groupadd --gid 54321 oinstall
groupadd --gid 54322 dba
groupadd --gid 54323 asmdba
groupadd --gid 54324 asmoper
groupadd --gid 54325 asmadmin

groupadd --gid 54330 racdba
useradd --uid 54321 --gid oinstall --groups dba,oper,asmdba,asmadmin,racdba,backupdba,dgdba,kmdba oracle
passwd oracle
useradd --uid 54322 --gid oinstall --groups dba,asmadmin,asmdba,asmoper,racdba grid
passwd grid
3. 操作系統創建軟件安裝目錄
vi /etc/oraInst.loc
inventory_loc=/oracle/app/oraInventory
inst_group=oinstall
# Create the Oracle Inventory Directory
# To create the Oracle Inventory directory, enter the following commands as the root user:
mkdir -p /oracle/app/oraInventory
chown -R grid:oinstall /oracle/app/oraInventory
chmod -R 775 /oracle/app/oraInventory
# Creating the Grid Infrastructure Base Directory
mkdir -p /oracle/app/grid
chown -R grid:oinstall /oracle/app/grid
chmod -R 775 /oracle/app/grid
# Creating the Oracle Grid Infrastructure Home Directory
mkdir -p /oracle/app/12.2.0/grid
chown -R grid:oinstall /oracle/app/12.2.0/grid
chmod -R 775 /oracle/app/12.2.0/grid
# Creating the Oracle Base Directory
mkdir -p /oracle/app/oracle
mkdir -p /oracle/app/oracle/cfgtoollogs
# needed to ensure that dbca is able to run after the rdbms installation.
chown -R oracle:oinstall /oracle/app/oracle
chmod -R 775 /oracle/app/oracle
# Creating the Oracle RDBMS Home Directory
mkdir -p /oracle/app/oracle/product/12.2.0/db_1
chown -R oracle:oinstall /oracle/app/oracle/product/12.2.0/db_1
chmod -R 775 /oracle/app/oracle/product/12.2.0/db_1
4. 操作系統內核參數優化
# 內存為128G,設置kernel.shmmax=70G,SGA=50G and PGA=10G
# kernel.shmmni該參數是系統共享內存段最大個數
# kernel.shmmax該參數是一個進程共享內存段最大尺度
# SHMMAX應略大于SGA尺寸
# kernel.shmall該參數是共享內存總量
# kernel.shmall大于shmmax/PAGE_SIZE
cat /etc/sysctl.conf
kernel.shmmni = 4096
kernel.shmmax = 75161927680
kernel.shmall = 18350080
kernel.sem = 250 32000 100 128
fs.file-max = 7553600
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
# 安裝數據庫實例后算出并添加此參數
vm.nr_hugepages = 25026
# 立即生效（root）
/sbin/sysctl -p
#NOTE: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/5/html/ tuning_and_optimizing_red_hat_enterprise_linux_for_oracle_9i_and_10g_databases/index
#NOTE: The latest information on kernel parameter settings for Linux can be found in My Oracle Support ExtNote:169706.1.#
5. 操作系統內存優化
# Oracle一直建議關閉Transparent HugePages來優化內存的使用,
# 故關閉Transparent HugePages
grubby --default-kernel
grubby --args="transparent_hugepage=never" --update-kernel
grubby --info /boot/vmlinuz-3.10.0-514.el7.x86_64 >> /boot/grub2/grub.cfg
cat /sys/kernel/mm/transparent_hugepage/enabled
grep AnonHugePages /proc/meminfo
reboot
# 節點1執行展示結果

always madvise [never]
[root@bmcdb1 ~]# grep AnonHugePages /proc/meminfo
AnonHugePages: 0 kB
# reboot 展示結果忽略
6. 操作系統共享內存優化
# Redhat 7.2以后systemd-logind service引入了新的功能,用戶注銷時,刪除所有IPC對象
# 避免用戶中斷時系統刪除共享SGA內存,
# 導致ASM和database instance down機,故設置RemoveIPC=no
echo "RemoveIPC=no" >> /etc/systemd/logind.conf
systemctl restart systemd-logind
# ALERT: Setting RemoveIPC=yes on Redhat 7.2 and higher Crashes ASM and Database Instances as Well as Any Application That Uses a Shared Memory Segment (SHM) or Semaphores (SEM) (文檔 ID 2081410.1)
# 節點1執行展示結果
[root@bmcdb1 ~]# echo "RemoveIPC=no" >> /etc/systemd/logind.conf
[root@bmcdb1 ~]# cat /etc/systemd/logind.conf
……中間展示忽略……
#RemoveIPC=no
RemoveIPC=no
# 設置共享內存
# 通過/etc/fstab設置共享內存
[root@bmcdb1 ~]# cat /etc/fstab

export TMPDIR=/tmp
umask=022
8. 操作系統用戶(oracle,grid)硬性限制優化
# 提升用戶硬性限制（Oracle、grid用戶默認的硬性限制不滿足GI安裝和配置）
# limits.conf為PAM模板配置文件；所以應先配置PAM,即配置如下：
echo "session required pam_limits.so" >> /etc/pam.d/login
# RAC未運行之前,無法實際測量vm.nr_hugepages大小。
# 原則：Number Hugepages * Hugepagesize = minimum Memlock < RAM
cat /etc/security/limits.conf
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240
oracle hard stack 32768
oracle soft memlock 134144000
oracle hard memlock 134144000
grid soft nproc 2047
grid hard nproc 16384
grid soft nofile 1024
grid hard nofile 65536
grid soft stack 10240
grid hard stack 32768
#NOTE：What is Memlock and How to Calculate the Values for Memlock (文檔 ID 2511230.1)
# shell開始文件限制提升
cat /etc/profile
if [ $USER = "oracle" ] || [ $USER = "grid" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
umask 022
fi
9. 操作系統關閉防火墻和selinux
# 關閉防火墻
systemctl status firewalld
systemctl start firewalld.service
systemctl stop firewalld.service
systemctl disable firewalld.service
systemctl status firewalld
# 永久關閉selinux
cat /etc/sysconfig/selinux
SELINUX=disabled
10. 操作系統安裝軟件用戶(oracle,grid)互信配置
# 在節點1配置ssh互信,步驟如下：
# 使用root將數據庫軟件拷貝至/home/oracle/下：
# 此腳本適合多節點安裝優先使用
# chown oracle:oinstall linuxx64_12201_database.zip
# su - oracle
$ unzip linuxx64_12201_database.zip
$ cd database/sshsetup/
$ ./sshUserSetup.sh -user oracle -hosts "node1 node2" -advanced -noPromptPassphrase
$ ./sshUserSetup.sh -user grid -hosts "node1 node2" -advanced -noPromptPassphrase
# 檢驗互信
# 節點1, bmcdb1上執行檢驗操作
$ ssh bmcdb1 date;ssh bmcdb2 date;ssh bmcdb1priv date;ssh bmcdb2priv date
# 節點2, bmcdb2上執行檢驗操作
$ ssh bmcdb1 date;ssh bmcdb2 date;ssh bmcdb1priv date;ssh bmcdb2priv date
11. 操作系統使用/etc/hosts解析
# /etc/hosts解析地址如下
[oracle@bmcdb1 ~]$ cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

8. RAC優化
1.安全
1.1 用戶密碼策略優化(可根據安全策略自行創建)
# FAILED_LOGIN_ATTEMPTS=>登錄錯誤次數限制
# PASSWORD_LIFE_TIME =>密碼有效期限制
ALTER PROFILE DEFAULT LIMIT FAILED_LOGIN_ATTEMPTS 30;
ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED;
1.2 優化低端版本的客戶端無法登錄12c高版本數據庫問題(所有節點配置)
[grid@bmcdb1:/oracle/app/12.2.0/grid/network/admin]$cat sqlnet.ora
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
SQLNET.ALLOWED_LOGON_VERSION=8
# MOS文檔 ID 2296947.1
2.實例優化
2.1 process進程數優化
# 操作系統用戶進程數和所有后臺進程最大值。
# 例如：locks\job queue processes\parallel execution processes
alter system set processes=2000 sid='*' scope=spfile;
2.2 實例本地進程并發優化
# 實現進程級別本地化并發處理，優化節點間通宵成本負載大的問題。
# PARALLEL_FORCE_LOCAL該參數默認是False。
alter system set parallel_force_local=true sid='*';
2.3 避免大量library cache lock導致用戶不能登錄的情況
# 關閉數據庫當中用戶持續輸入錯誤密碼導致大量library cache lock
alter system set event ="28401 TRACE NAME CONTEXT FOREVER, LEVEL 1" sid='*' scope=spfile;
2.4 DBLINK使用insert優化
# 高版本數據庫dblink插入低版本數據庫，insert語法最后一個bind不是varchar2時，# 報錯ORA-01483或者ORA-01461
# 參考：OCI Application Fails With ORA-01483/ORA-01461 When Inserting VARCHAR2 Field From 12.2/18c Database Using Database Link To Lower Database Version. (文檔 ID 2309285.1)
alter system set "_qkslvc_extended_bind_sz"=0 sid='*';
2.5 12.2 RAC 避免DataPump導入出現大量'Library Cache Lock' (Cycle)
# datapump時parallel>1可能觸發BUG，引起大量'Library Cache Lock' (Cycle)問題
parallel = 1 運行元數據導入（默認值）。
2.6 增加 db_files
# How to change the DB_FILES parameter in RAC (文檔 ID 1636681.1)
alter system set db_files=500 sid='*' scope=spfile;
srvctl stop database -d bmcdb
srvctl start database -d bmcdb
# MAXDATAFILES為自動擴展，oracle 8 版本以后
3.系統優化
3.1 大頁使用優化
所有實例使用hugepages_settings.sh腳本計算vm.nr_hugepages值,停止所有實例后，將計算出的vm.nr_hugepages = 25026 添加至/etc/sysctl.conf，并設置立即生效 sysctl -p
# 參考：Oracle Linux: Shell Script to Calculate Values Recommended Linux HugePages / HugeTLB Configuration (文檔 ID 401749.1)
[root@bmcdb1 ~]# sh hugepages_settings.sh
This script is provided by Doc ID 401749.1 from My Oracle Support
(http://support.oracle.com) where it is intended to compute values for
the recommended HugePages/HugeTLB configuration for the current shared
memory 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 SGA 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
Press Enter to proceed...
Recommended setting: vm.nr_hugepages = 25026
[root@bmcdb1 ~]# grep HugePages /proc/meminfo
AnonHugePages: 0 kB
HugePages_Total: 0
HugePages_Free: 0
HugePages_Rsvd: 0
HugePages_Surp: 0
[root@bmcdb1 ~]# sysctl -p
……
vm.nr_hugepages = 25026
[root@bmcdb1 ~]# grep HugePages /proc/meminfo
AnonHugePages: 0 kB
HugePages_Total: 25026
HugePages_Free: 25026
HugePages_Rsvd: 0
HugePages_Surp: 0
