19c RAC Duplicate方式静默安装ADG从库
2024-06-23 06:09:05
前期安装的环境配置
一、安装19c必要的依赖包
yum install bc binutils compat-libcap1 compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel fontconfig-devel glibc glibc-devel ksh libaio libaio-devel libX11 libXau libXi libXtst libXrender libXrender-devel libgcc libstdc++ libstdc++-devel libxcb make smartmontools sysstat librdmacm-devel libXext libaio.i686 libstdc++-devel.i686 libstdc++.i686 libgcc.i686 glibc-devel.i686
yum install ipmiutil net-tools nfs-utils python python-configshell python-rtslib python-six targetcli compat-libstdc++-33.i686 gcc compat-libstdc++ readline libtermcap-devel unixODBC-devel unixODBC libXi.i686 libxcb.i686 libXau.i686 libX11.i686 libXtst.i686 libXext.i686 gcc-c++ glibc glibc.i686 libaio-devel.i686
rpm -ivh compat-libstdc++-33-3.2.3-72.el7.x86_64.rpm二、关闭ntpd服务
[root@rac1 ~]#systemctl disable ntpd.service
[root@rac1 ~]#systemctl stop ntpd.service
[root@rac1 ~]#mv /etc/ntp.conf /etc/ntp.conf.orig
[root@rac1 ~]#systemctl status ntpd三、关闭防火墙
[root@rac01 ~]# systemctl stop firewalld
[root@rac01 ~]# systemctl disable firewalld
[root@rac01 ~]# systemctl status firewalld四、关闭avahi-daemon服务，官网建议关闭
[root@rac01 ~]# systemctl stop avahi-daemon
Warning: Stopping avahi-daemon.service, but it can still be activated by:avahi-daemon.socket
[root@rac01 ~]# systemctl disable avahi-daemon
Removed symlink /etc/systemd/system/multi-user.target.wants/avahi-daemon.service.
Removed symlink /etc/systemd/system/sockets.target.wants/avahi-daemon.socket.
Removed symlink /etc/systemd/system/dbus-org.freedesktop.Avahi.service.五、创建用户及用户组
[root@rac1 ~]
groupadd -g 16881 oinstall
groupadd -g 16882 dba
groupadd -g 16883 oper
groupadd -g 16884 backupdba
groupadd -g 16885 dgdba
groupadd -g 16886 kmdba

useradd -u 16882 -g oinstall -G asmadmin,asmdba,asmoper,dba grid六、创建文件目录（在两个节点创建grid、oracle文件目录）
[root@rac1 ~]
mkdir -p /u01/app/19.0.0/grid
mkdir -p /u01/app/grid
mkdir -p /u01/app/oracle
mkdir -p /u01/app/oracle/product/19.0.0/db_1
chown -R grid:oinstall /u01
chown -R oracle:oinstall /u01/app/oracle
chmod -R 775 /u01/七、修改limits.conf（在两个节点修改）
[root@rac1 ~]vi /etc/security/limits.conf
#ORACLE SETTING
grid soft nproc 16384
grid hard nproc 16384
grid soft nofile 1024
grid hard nofile 65536
grid soft stack 10240
grid hard stack 32768
oracle soft nproc 16384
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240
oracle hard stack 32768
oracle hard memlock 3145728
oracle soft memlock 3145728八、添加 vi /etc/pam.d/login
session required pam_limits.so
九、配置NOZEROCONF
vi /etc/sysconfig/network增加以下内容
NOZEROCONF=yes十、配置sysctl.conf
[root@rac1 ~]vi /etc/sysctl.conf
#ORACLE SETTING
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmmax = 269509197824
kernel.shmall = 65798144
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 = 104858十一、关闭大页
echo "never" > /sys/kernel/mm/transparent_hugepage/enabled
echo "never" > /sys/kernel/mm/transparent_hugepage/defrag
chmod +x /etc/rc.d/rc.local十二、CentOS7关闭networkmanager
[root@p4181-170 ~]# systemctl stop NetworkManager
[root@p4181-170 ~]# systemctl disable NetworkManager
[root@p4181-170 ~]# mkdir -p /u01/app/oracle/product/19.0.0/db_1
[root@p4181-170 ~]# chown -R oracle:oinstall /u01
[root@p4181-170 ~]# chmod -R 775 /u01十三、安装19c数据库包并提前安装cvuqdisk包
mv LINUX.X64_193000_db_home.zip $ORACLE_HOME
rpm -ivh $ORACLE_HOME/cv/rpm/cvuqdisk-1.0.10-1.rpm十四、编辑响应文件
cd $ORACLE_HOME/install/response/db_install.rsp
oracle.install.option=INSTALL_DB_SWONLY
UNIX_GROUP_NAME=oinstall
INVENTORY_LOCATION=/u01/app/oraInventory
ORACLE_HOME=/u01/app/oracle/product/19.0.0/db_1
ORACLE_BASE=/u01/app/oracle
oracle.install.db.InstallEdition=EE
oracle.install.db.rootconfig.executeRootScript=false
oracle.install.db.OSDBA_GROUP=dba
oracle.install.db.OSOPER_GROUP=oper
oracle.install.db.OSBACKUPDBA_GROUP=backupdba
oracle.install.db.OSDGDBA_GROUP=dgdba
oracle.install.db.OSKMDBA_GROUP=kmdba
oracle.install.db.OSRACDBA_GROUP=racdba
oracle.install.db.rootconfig.configMethod=ROOT
/u01/app/oracle/product/19.0.0/db_1/runInstaller -silent -force -noconfig -ignorePrereq -responseFile /u01/app/oracle/product/19.0.0/db_1/install/response/db_install.rsp
***************************************************************************十五、如果安装单节点数据库，编辑数据库响应文件
（1）配置db相应文件内容
vi dbca.rsp
gdbName=SAASN
sid=SAASN
createAsContainerDatabase=true
numberOfPDBs=1
pdbName=PRODPDB
pdbAdminPassword=xxxxx
templateName=General_Purpose.dbc
sysPassword=xxxx
systemPassword=xxxxx
emExpressPort=5500
datafileDestination={ORACLE_BASE}/oradata/{DB_UNIQUE_NAME}/
characterSet=AL32UTF8
nationalCharacterSet=AL16UTF16
memoryPercentage=40
automaticMemoryManagement=false
totalMemory=30720
（2）安装数据库
dbca -silent -createDatabase -responseFile
/u01/app/oracle/product/19.0.0/db_1/install/response/dbca.rsp
****************************************************************************前期环境设置完成后，开始配置ADG的必要参数
十六、主库开启强制记录日志和归档模式
SQL> select force_logging from v$database;如果开启闪回，归档日志需提前开启
SQL> alter system set db_recovery_file_dest='+FRA' scope=spfile;
SQL> alter system set db_recovery_file_dest_size=688G scope=spfile;RAC环境关闭所有节点数据库，只开启一个节点到mount状态，开启强制归档模式。
[grid@rac01.hkrt.cn:/home/grid]$srvctl stop database -d saas
[grid@rac01.hkrt.cn:/home/grid]$srvctl start instance -d saas -i saas1 -o mount
SQL> alter database flashback on;
SQL> alter database force logging;
[grid@rac01.hkrt.cn:/home/grid]$srvctl stop database -d saas
[grid@rac01.hkrt.cn:/home/grid]$srvctl start database -d saas
SQL> select name,log_mode,flashback_on from v$database;
NAME LOG_MODE FLASHBACK_ON
------------------ ------------------------ ------------------------------------
SAAS ARCHIVELOG YES十七、RAC环境配置控制文件多路径。避免单文件损坏
SQL> alter system set control_files='+DATA/SAAS/CONTROLFILE/current.261.1076090117','+DATA/SAAS/CONTROLFILE/control02.ctl' scope=spfile;
[root@rac01 tmp]# srvctl stop database -d saas
[grid@rac01.hkrt.cn:/home/grid]$asmcmd
ASMCMD> cd DATA
ASMCMD> cd SAAS
ASMCMD> cd CONTROLFILE
ASMCMD> ls
Current.261.1076090117
ASMCMD> cp Current.261.1076090117 control02.ctl
copying +DATA/SAAS/CONTROLFILE/Current.261.1076090117 -> +DATA/SAAS/CONTROLFILE/control02.ctl
[root@rac01 tmp]# srvctl start database -d saas十八、根据主库RAC的日志数量，添加standby日志组+1。
SQL> select group#,members,thread#,bytes/1024/1024 from v$log;GROUP# MEMBERS THREAD# BYTES/1024/1024
---------- ---------- ---------- ---------------1 1 1 10242 1 1 10243 1 1 10244 1 1 10245 1 1 10246 1 1 10247 1 1 10248 1 1 102411 1 2 102412 1 2 102413 1 2 102414 1 2 102415 1 2 102416 1 2 102417 1 2 102418 1 2 1024
alter database add standby logfile thread 1 group 21 '+DATA/SAAS/ONLINELOG/stdgroup_21.log' size 1024m;
alter database add standby logfile thread 1 group 22 '+DATA/SAAS/ONLINELOG/stdgroup_22.log' size 1024m;
alter database add standby logfile thread 1 group 23 '+DATA/SAAS/ONLINELOG/stdgroup_23.log' size 1024m;
alter database add standby logfile thread 1 group 24 '+DATA/SAAS/ONLINELOG/stdgroup_24.log' size 1024m;
alter database add standby logfile thread 1 group 25 '+DATA/SAAS/ONLINELOG/stdgroup_25.log' size 1024m;
alter database add standby logfile thread 1 group 26 '+DATA/SAAS/ONLINELOG/stdgroup_26.log' size 1024m;
alter database add standby logfile thread 1 group 27 '+DATA/SAAS/ONLINELOG/stdgroup_27.log' size 1024m;
alter database add standby logfile thread 1 group 28 '+DATA/SAAS/ONLINELOG/stdgroup_28.log' size 1024m;
alter database add standby logfile thread 1 group 29 '+DATA/SAAS/ONLINELOG/stdgroup_29.log' size 1024m;
alter database add standby logfile thread 2 group 31 '+DATA/SAAS/ONLINELOG/stdgroup_31.log' size 1024m;
alter database add standby logfile thread 2 group 32 '+DATA/SAAS/ONLINELOG/stdgroup_32.log' size 1024m;
alter database add standby logfile thread 2 group 33 '+DATA/SAAS/ONLINELOG/stdgroup_33.log' size 1024m;
alter database add standby logfile thread 2 group 34 '+DATA/SAAS/ONLINELOG/stdgroup_34.log' size 1024m;
alter database add standby logfile thread 2 group 35 '+DATA/SAAS/ONLINELOG/stdgroup_35.log' size 1024m;
alter database add standby logfile thread 2 group 36 '+DATA/SAAS/ONLINELOG/stdgroup_36.log' size 1024m;
alter database add standby logfile thread 2 group 37 '+DATA/SAAS/ONLINELOG/stdgroup_37.log' size 1024m;
alter database add standby logfile thread 2 group 38 '+DATA/SAAS/ONLINELOG/stdgroup_38.log' size 1024m;
alter database add standby logfile thread 2 group 39 '+DATA/SAAS/ONLINELOG
/stdgroup_39.log' size 1024m;十九、主库配置传输到从库的参数文件。
SQL> alter system set LOG_ARCHIVE_CONFIG='DG_CONFIG=(saas,saasdg)' scope=both;
SQL> alter system set LOG_ARCHIVE_DEST_1='LOCATION=+FRA/saas/archivelog VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=saas' scope=both;
配置传输到备库的传输路径
SQL> alter system set LOG_ARCHIVE_DEST_2='SERVICE=saasdg LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=saasdg' scope=both;
SQL> alter system set LOG_ARCHIVE_DEST_STATE_1=ENABLE;
SQL> alter system set LOG_ARCHIVE_DEST_STATE_2=ENABLE;
SQL> alter system set FAL_SERVER=saasdg;
SQL> alter system set FAL_CLIENT=saas;注意：db_file_name_convert与log_file_name_convert，主库传输时是读取的备库的参数，这里主库配置是基于可能发生切换变成备库时所需。
SQL> alter system set DB_FILE_NAME_CONVERT='/u01/app/oracle/oradata/saasdg/datafile/','+DATA/SAAS/DATAFILE/','/u01/app/oracle/oradata/saasdg/tempfile/','+DATA/SAAS/TEMPFILE/' scope=spfile;
SQL> alter system set LOG_FILE_NAME_CONVERT='/u01/app/oracle/oradata/saasdg/onlinelog/','+DATA/SAAS/ONLINELOG/' scope=spfile;
SQL> alter system set remote_login_passwordfile='EXCLUSIVE' scope=spfile;
SQL> alter system set log_archive_format='%t_%s_%r.arch' scope=spfile;
SQL> alter system set STANDBY_FILE_MANAGEMENT=AUTO;二十、创建PFILE，拷贝密码文件传输到备库。
create pfile='/home/oracle/initsaasdg.ora' from spfile;
[grid@rac01.hkrt.cn:/home/grid]$asmcmd
ASMCMD> cd PASSWORD
ASMCMD> ls
pwdsaas.256.1076089961
ASMCMD> cp pwdsaas.256.1076089961 /tmp/orapwsaasdg
copying +DATA/SAAS/PASSWORD/pwdsaas.256.1076089961 -> /tmp/orapwsaasdg
[oracle@p4.hkrt.cn:/home/oracle]$mv orapwsaasdg $ORACLE_BASE/product/19.0.0/db_1/dbs/
