5.多路徑軟件multipath

安裝multipath(兩邊都要)

先裝device-mapper-multipath-libs-0.4.9-64.0.1.el6.x86_64.rpm

[root@rbdb81 soft]# rpm -Uvh device-mapper-multipath-libs-0.4.9-64.0.1.el6.x86_64.rpm

再裝rpm -Uvh device-mapper-multipath-0.4.9-64.0.1.el6.x86_64.rpm

[root@rbdb81 soft]# rpm -Uvh device-mapper-multipath-0.4.9-64.0.1.el6.x86_64.rpm

Multipath相關說明

 

使用Multipath進行多鏈路聚合並對聚合後的設備固定命名

 

配置multipath

1、啓用Multipath：

 

（1）啓動multipathd服務

#service multipathd start 或者 #/etc/init.d/multipathd start

 

（2）修改multipath配置文件/etc/multipath.conf：

# cp /usr/share/doc/device-mapper-multipath-0.4.9/multipath.conf

         /etc/multipath.conf

 

(能夠vi /etc/multipath/ bindings查看)

[oracle@rbdb81 ~]$ vi /etc/multipath.conf

defaults { user_friendly_names yes path_grouping_policy multibus find_multipaths  yes } blacklist { wwid 3600508b1001cb4c7c0d68a3645bf5dde #這是一號節點備份盤. devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*" devnode "^hd[a-z]" }   multipaths { multipath {                wwid                    3600c0ff0001977f5d5a0835201000000                alias                   mpath0                path_grouping_policy    multibus                path_selector           "round-robin 0"                failback                immediate                rr_weight               uniform                no_path_retry           18 } multipath {                wwid3600c0ff0001977f5eba0835201000000                alias                   mpath1                path_grouping_policy    multibus                path_selector           "round-robin 0"                failback                immediate                rr_weight               uniform                no_path_retry           18 } multipath {                wwid3600c0ff0001977f5a0a0835201000000                alias                   mpath2                path_grouping_policy    multibus                path_selector           "round-robin 0"                failback                immediate                rr_weight               uniform                no_path_retry           18 } multipath {                wwid3600c0ff0001977f5eda3845201000000                alias                   mpath3                path_grouping_policy    multibus                path_selector           "round-robin 0"                failback                immediate                rr_weight               uniform                no_path_retry           18 } multipath {                wwid3600c0ff0001977f53da4845201000000                alias                   mpath4                path_grouping_policy    multibus                path_selector           "round-robin 0"                failback                immediate                rr_weight               uniform                no_path_retry           18 } multipath {                wwid3600c0ff00019869012a1835201000000                alias                   mpath5                path_grouping_policy    multibus                path_selector           "round-robin 0"                failback                immediate                rr_weight               uniform                no_path_retry           18 } }

 

（3）重啓multipathd服務（修改multipath.conf文件以後都應該重啓multipath服務）

multipath -F

 

（4）掃描磁盤

#multipath -v2

使用上面命令以後，系統中會出現鏈路聚合以後的dm設備，同時也會在/dev/mapper/、/dev/mpath/目錄下生成相應的設備。

查看multipath拓撲結構

#multipath -ll

 

[root@rbdb81 ~]# multipath -ll mpath2 (3600c0ff0001977f5a0a0835201000000) dm-0 HP,P2000 G3 FC size=1.9G features='1 queue_if_no_path' hwhandler='0' wp=rw `-+- policy='round-robin 0' prio=70 status=active |- 0:0:0:1 sda 8:0   active ready running `- 1:0:0:1 sdi 8:128 active ready running mpath1 (3600c0ff0001977f5eba0835201000000) dm-4 HP,P2000 G3 FC size=1.9G features='1 queue_if_no_path' hwhandler='0' wp=rw `-+- policy='round-robin 0' prio=70 status=active |- 0:0:0:3 sdc 8:32  active ready running `- 1:0:0:3 sdk 8:160 active ready running mpath0 (3600c0ff0001977f5d5a0835201000000) dm-3 HP,P2000 G3 FC size=1.9G features='1 queue_if_no_path' hwhandler='0' wp=rw `-+- policy='round-robin 0' prio=70 status=active |- 0:0:0:2 sdb 8:16  active ready running `- 1:0:0:2 sdj 8:144 active ready running mpath5 (3600c0ff00019869012a1835201000000) dm-2 HP,P2000 G3 FC size=1.1T features='1 queue_if_no_path' hwhandler='0' wp=rw `-+- policy='round-robin 0' prio=70 status=active |- 0:0:0:5 sde 8:64  active ready running `- 1:0:0:5 sdm 8:192 active ready running mpath4 (3600c0ff0001977f53da4845201000000) dm-5 HP,P2000 G3 FC size=831G features='1 queue_if_no_path' hwhandler='0' wp=rw `-+- policy='round-robin 0' prio=70 status=active |- 0:0:0:6 sdf 8:80  active ready running `- 1:0:0:6 sdn 8:208 active ready running mpath3 (3600c0ff0001977f5eda3845201000000) dm-1 HP,P2000 G3 FC size=1.4T features='1 queue_if_no_path' hwhandler='0' wp=rw `-+- policy='round-robin 0' prio=70 status=active |- 0:0:0:4 sdd 8:48  active ready running `- 1:0:0:4 sdl 8:176 active ready running

 

（5）關掉其它節點的multipathd 服務

     service multipathd stop

 (6) 拷貝multipath.conf 到其它節點

scp /etc/multipath.conf rbdb82:/etc/

 (7) 起動其它節點服務

multipath –F multipath –v2 multipath –ll

 

(8)設置自動啓服務(全部節點都設)

/etc/init.d/multipathd restart chkconfig --list multipathd chkconfig --level 3456 multipathd on chkconfig multipathd

 

3安裝檢查及配置

1．檢查硬件

    內存，swap，tmp，安裝軟件的磁盤空間，shared storage

2．網卡

    最少兩塊網卡

    最好5塊網卡，2塊綁定爲public，2塊綁定爲private，一塊做爲archive log用。不要把一卡上面的多個口子綁定在一塊兒。

    保證全部節點上public，private的接口名稱相同。例如：en0在node1上是public，那麼在node2上面，它的en0也必須是public。private同理。集羣中全部節點的private接口必須能互相訪問，配通。

3．建立用戶組及用戶

（兩節點都要執行）

 

groupadd -g 501 oinstall

groupadd -g 502 dba

groupadd -g 503 asmadmin

groupadd -g 504 asmdba

groupadd -g 505 asmoper

 

useradd -u 501 -g oinstall -G asmadmin,asmdba,asmoper grid

useradd -u 502 -g oinstall -G dba,asmdba oracle

 

# passwd oracle

Changing password for user oracle.

New UNIX password:

BAD PASSWORD: it is based on a dictionary word

Retype new UNIX password:

passwd: all authentication tokens updated successfully.

# passwd grid

Changing password for user grid.

New UNIX password:

BAD PASSWORD: it is based on a dictionary word

Retype new UNIX password:

passwd: all authentication tokens updated successfully.

[root@node1 ~]#

4．網絡

注意:下劃線不能用做主機名。最好使用小寫，不帶下劃線，中劃線。

 

說明:推薦使用網卡綁定，而且最還使用主備模式。

cluster name必須知足：在整個域中的globally unique。最少一個字符，小於15個字符，與hostname的字符集相同

public host name：使用每一個主機的primary host name。即：使用hostname命令顯示出來的名稱。

 

virtual hostname：The virtual host name is a public nodename that is used to reroute client requests sent to the node if the node is down。推薦的命名方式<public hostname>-vip，最好仍是別用中劃線。

VIP：必須沒有使用，與public ip處於同一個子網段。必須解析（/etc/hosts或者dns）

private hostname：不須要通過dns解析，可是必須在/etc/hosts中配置。推薦命名方式<public hostname>pvt。也最好別用中劃線。

private ip：不能被集羣以外的servers訪問；private net應該在獨立的交換網絡上；private net不該該是大環境的網絡top的一部分；private net應該部署在千兆或者更好的以太網上。

SCANIP:多個scanIP的話不能配置在/etc/hosts，只能在DNS中，否則就只有一個生效。若是在dns中配置了ip，那麼就得在全部節點上更改主機的搜索順序

 

/etc/hosts配置：

（兩節點都要執行）

 

#Public 192.168.1.108 rbdb81 192.168.1.109 rbdb82 #VIP 192.168.1.208 rbdb81vip 192.168.1.209 rbdb82vip   #Private 192.168.2.108 rbdb81priv 192.168.2.109 rbdb82priv #scan 192.168.1.210 rbdb8scan   192.168.1.100 rbdb1 192.168.1.101 rbdb2 192.168.1.102 rbdb3 192.168.1.104 rbdb4 192.168.1.105 rbdb05 192.168.1.106 rbdb06 192.168.1.107 rbdb07 192.168.1.200 vip-rbdb1 192.168.1.201 vip-rbdb2 192.168.1.205 rbdb05-vip 192.168.1.206 rbdb06-vip

 

 

 

5．時間同步

    若是使用ntp同步，那麼須要額外配置，若是使用Oracle Cluster Time Synchronization

Service (ctssd)同步，那麼就不須要配置了。使用ctssd要作如下操做:

#Network Time Protocol Setting

停掉服務

/sbin/service ntpd stop

chkconfig ntpd off

刪除ntp.conf 文件或更名:

rm /etc/ntp.conf

或

mv /etc/ntp.conf to /etc/ntp.conf.org

 

6．內核參數

（兩節點都要執行）

 

root用戶更改(如下改系統參數據都在ROOT)

 

/etc/sysctl.conf

 

kernel.shmmni = 4096 kernel.sem = 250 32000 100 128 fs.file-max = 6553600 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 kernel.shmall = 8388608 fs.file-max = 6815744 fs.aio-max-nr = 1048576

 

#/sbin/sysctl -p當即生效

說明:因爲 kernel.shmall設置的爲默認的2097152也就是最小值設置，

個人機器是64GB內存的 應該設置爲以下 ，或者更大才行。

kernel.shmall =8388608

For example, if the sum of all the SGAs on the system is 16Gb and the result of '$ getconf PAGE_SIZE' is 4096 (4Kb) then set shmall to 4194304 (4Mb)

 

7．限制參數

（在ROOT下,兩節點都要執行）

 

/etc/security/limits.conf

 

grid soft nproc 2047 grid hard nproc 16384 grid soft nofile 1024 grid hard nofile 65536 oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536

 

/etc/pam.d/login file,若是不存在就加上一下行

session required pam_limits.so

 

 

/etc/profile，增長如下內容

 

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

 

若是是C-shell

For the C shell (csh or tcsh), add the following lines to the /etc/csh.login file:

if ( $USER = "oracle" || $USER = "grid" ) then

limit maxproc 16384

limit descriptors 65536

endif

 

在其餘節點上重複上述操做

 

8．建立目錄

（在ROOT下,兩節點都要執行）

 

oracle Inventory Directory

其實能夠不用建立，初始目錄只要權限夠了，那麼安裝時會自動建立。

mkdir -p /u01/app/oraInventory

chown -R grid:oinstall /u01/app/oraInventory

chmod -R 775 /u01/app/oraInventory

 

建立grid 的 ORACLE_HOME 目錄

mkdir -p /u01/app/grid/product/11.2.0

chown -R grid:oinstall /u01/app/grid/product/11.2.0

chmod -R 775 /u01/app/grid/product/11.2.0

 

建立oracle 的ORACLE_BASE目錄

mkdir -p /u01/app/oracle

mkdir /u01/app/oracle/cfgtoollogs

chown -R oracle:oinstall /u01/app/oracle

chmod -R 775 /u01/app/oracle

 

建立rdbms 的 ORACLE_HOME目錄

mkdir -p /u01/app/oracle/product/11.2.0/db_1

chown -R oracle:oinstall /u01/app/oracle/product/11.2.0/db_1

chmod -R 775 /u01/app/oracle/product/11.2.0/db_1

9．檢查軟件環境

如下是Oracle Enterprise Linux 5 64位系統須要的包

 

binutils-2.15.92.0.2

10.關閉SELINUX和服務

Vi /etc/selinux/config

 

SELINUX=disabled

 

關掉防火牆

[root@rbdb81 Packages]# chkconfig --level 2345 ip6tables off

[root@rbdb81 Packages]# chkconfig --level 2345 iptables off

 

關服務

11. ASM

有兩個不一樣方法可在 Linux 上配置 ASM：

使用 ASMLib I/O 的 ASM：此方法使用 ASMLib 調用在由 ASM 管理的原始塊設備上建立全部 Oracle 數據庫文件。因爲 ASMLib 使用塊設備，所以該方法不須要原始設備。

使用標準 Linux I/O 的 ASM：此方法使用標準 Linux I/O 系統調用在 ASM 管理的原始字符設備上建立全部 Oracle 數據庫文件。您將須要爲 ASM 使用的全部磁盤分區建立原始設備。 (裸設備)

咱們將在此處介紹「使用 ASMLib I/O 的 ASM」。

 

安裝ASM

下載ASMLib

首先，從  Red Hat找到 kmod-oracleasm來安裝oracleasm ，oracleasm-2.6.9-22.ELsmp-2.0.0-1.x86_64.rpm -（適用於多處理器）從這個網址(http://www.oracle.com/technology/global/cn/tech/linux/asmlib/install.html)下載ASMLib 軟件。首先，下載適用於多處理器 Linux 服務器的爲 ASM 庫提供內核驅動程序：

還將須要下載如下兩個支持文件：

oracleasmlib-2.0.0-1.x86_64.rpm -（提供實際的 ASM 庫）
oracleasm-support-2.0.0-1.x86_64.rpm -（提供用來使 ASM 驅動程序啓動並運行的公用程序）

 

安裝ASMLib

咱們將把ASMLib文件安裝到兩臺多處理器計算機中。安裝過程只須要您以 root 用戶賬戶的身份在集羣中的全部節點上運行如下命令便可：

[root@rbdb82 asm]# ls -l

total 128

-rwxr-xr-x 1 oracle oinstall 33840 May 31 11:48 kmod-oracleasm-2.0.6.rh1-2.el6.x86_64.rpm

-rwxr-xr-x 1 oracle oinstall 13300 Oct 12 17:30 oracleasmlib-2.0.4-1.el6.x86_64.rpm

-rwxr-xr-x 1 oracle oinstall 74984 Oct 12 17:30 oracleasm-support-2.1.8-1.el6.x86_64.rpm

[root@rbdb82 asm]#

rpm -ivh  oracleasm-support-2.1.8-1.el6.x86_64.rpm

rpm -ivh  kmod-oracleasm-2.0.6.rh1-2.el6.x86_64.rpm

rpm -ivh  oracleasmlib-2.0.4-1.el6.x86_64.rpm

配置 ASMLib

   如今已經安裝了 ASMLib 軟件，系統管理員必須執行幾個步驟來使 ASM 驅動程序可用。須要加載 ASM 驅動程序，而且須要裝載驅動程序文件系統。數據庫以 ' grid ' 用戶和 ' oinstall' 用戶組身份運行，安裝過程只須要您以 root 用戶賬戶的身份在集羣中的全部節點上運行如下命令便可：

/etc/init.d/oracleasm configure

Configuring the Oracle ASM library driver. This will configure the on-boot properties of the Oracle ASM library driver. The following questions will determine whether the driver is loaded on boot and what permissions it will have. The current values will be shown in brackets ('[]'). Hitting <ENTER> without typing an answer will keep that current value. Ctrl-C will abort. Default user to own the driver interface []:grid Default group to own the driver interface []:asmadmin Start Oracle ASM library driver on boot (y/n) [n]:y Scan for Oracle ASM disks on boot (y/n) [y]:y Writing Oracle ASM library driver configuration: done Initializing the Oracle ASMLib driver: [ OK ] Scanning the system for Oracle ASMLib disks: [ OK ]

 

這應加載 oracleasm.o 驅動程序模塊並裝載 ASM 驅動程序文件系統。經過在配置期間選擇 enabled = 'y'，系統將始終在啓動時加載該模塊並裝載文件系統。

 

使磁盤對 ASMLib 可用

（注意：與本節中的其餘任務不一樣，建立ASMLib文件系統應只在一個節點上執行。咱們將只從 linux1執行本節中的全部命令。）

   系統管理員有最後一項任務。須要使 ASMLib 要訪問的每個磁盤可用。這是經過建立一個 ASM 磁盤來實現的。/etc/init.d/oracleasm 腳本將再次用於這個任務：

 

/etc/init.d/oracleasm createdisk  OCR_VOTE01     /dev/mapper/mpath0

/etc/init.d/oracleasm createdisk  OCR_VOTE02     /dev/mapper/mpath1

/etc/init.d/oracleasm createdisk  OCR_VOTE03     /dev/mapper/mpath2

/etc/init.d/oracleasm createdisk  DATA01         /dev/mapper/mpath3

/etc/init.d/oracleasm createdisk  DATA02/dev/mapper/mpath4

/etc/init.d/oracleasm createdisk  ARCH           /dev/mapper/mpath5

 

若是要刪除，須要執行：

/etc/init.d/oracleasm deletedisk  DATA01

 

/etc/init.d/oracleasm deletedisk  /dev/mapper/mpath3

 

當向 RAC 設置中添加磁盤時，須要通知其餘節點該磁盤的存在。在一個節點上運行 'createdisk' 命令，而後在其餘每個節點上運行 'scandisks'：

/etc/init.d/oracleasm scandisks

 

列出和查詢現有的磁盤

咱們可使用如下命令在全部節點上以 root用戶賬戶的身份測試是否成功建立了 ASM 磁盤：

/etc/init.d/oracleasm listdisks;

ARCH

DATA01

DATA02

OCR_VOTE01

OCR_VOTE02

OCR_VOTE03

其餘命令說明

能夠利用 /etc/init.d/oracleasm 的 'enable' 和 'disable' 選項來啓用或禁用自動啓動。

/etc/init.d/oracleasm disable

Writing Oracle ASM library driver configuration            [  OK  ]

Unmounting ASMlib driver filesystem                        [  OK  ]

Unloading module "oracleasm"                               [  OK  ]

 

/etc/init.d/oracleasm enable

Writing Oracle ASM library driver configuration            [  OK  ]

Loading module "oracleasm"                                 [  OK  ]

Mounting ASMlib driver filesystem                          [  OK  ]

Scanning system for ASM disks                              [  OK  ]

 

磁盤名稱是 ASCII 大寫字母、數字和下劃線。它們必須以字母開始。

再也不被 ASM 使用的磁盤也能夠取消標記：

/etc/init.d/oracleasm deletedisk VOL1

Deleting Oracle ASM disk "VOL1"                            [OK  ]

 

能夠查詢任意的操做系統磁盤，以瞭解它是否被 ASM 使用：

/etc/init.d/oracleasm querydisk   

/etc/init.d/oracleasm querydisk   ASM1

Checking if device "/dev/sdg" is an Oracle ASM disk        [  OK  ]

 

Linux ASMLib 的發現字符串

   ASMLib 使用發現字符串來肯定 ASM 正在請求哪些磁盤。通常的 Linux ASMLib 使用 glob 字符串。字符串必須以 "ORCL:" 爲前綴。磁盤經過名稱來指定。能夠經過發現字符串 "ORCL:VOL1" 在 ASM 中，發現以名稱 "VOL1" 建立的磁盤。相似地，能夠用發現字符串 "ORCL:VOL*" 來查詢全部以字符串 "VOL" 開始的磁盤。

不能在發現字符串中用路徑名稱來發現磁盤。若是缺乏前綴，那麼通常的 Linux ASMLib 將徹底忽略發現字符串，認爲它適用於一個不一樣的 ASMLib。惟一的例外是空字符串 ("")，它被認爲是一個全通配符。這與發現字符串 "ORCL:*" 徹底等價。

 

注意：一旦您用 Linux ASMLib 標記了磁盤，那麼OUI 將不能發現您的磁盤。建議您完成「僅限於軟件」 (Software Only) 的安裝，而後使用 DBCA 來建立數據庫（或者使用自定義安裝）。

 

 檢查 SAM磁盤權限：

[root@rbdb81 ~]# ll /dev/oracleasm/disks/

brw-rw---- 1 grid asmadmin 8,  0 Nov 15 15:36 OCR_VOTE03

 

注意2兩個問題:

1,若是ASM服務沒法自啓動，則加如下兩條命令

su – root

cd /etc/rc5.d/

ln -s ../init.d/oracleasm S99oracleasm

ln -s ../init.d/oracleasm K01oracleasm 

 

2,修改全部節點/etc/sysconfig/oracleasm文件(很重要)

 

ORACLEASM_ENABLED=true

ORACLEASM_UID=grid

ORACLEASM_GID=asmadmin

ORACLEASM_SCANBOOT=true

ORACLEASM_SCANORDER="mpath sd"

12.上傳11G和RAC安裝包解壓

 

unzip p10404530_112030_Linux-x86-64_1of7.zip

unzip p10404530_112030_Linux-x86-64_2of7.zip

unzip p10404530_112030_Linux-x86-64_3of7.zip

 

chown -R grid:oinstall grid

chown -R oracle:oinstall database

4.GI安裝

su - grid

grid的環境變量：rbdb81和rbdb82相同

vi /home/grid/.bash_profile

 

ORACLE_BASE=/u01/app/oracle ORACLE_HOME=/u01/app/grid/product/11.2.0 ORACLE_SID=+ASM1#在2節點爲+ASM2 LANG=C PATH=$ORACLE_HOME/bin:$PATH:$HOME/bin export PATH ORACLE_BASE ORACLE_HOME ORACLE_SID LANG

 

開始安裝GI

cd /soft/11grac/grid

./runInstaller

 

安裝以前檢查節點時間要差很少相同，由於自動同步服務尚未，只有安裝完成後纔有。

上面一步添加好之後點擊setup建立互信

 

 

能夠在test一下

rbdb81->grid>上執行

[grid@rbdb81 ~]$ ssh rbdb82 date

2013年 11月 5日 星期四 17:27:58 CST

[grid@node1 ~]$

rbdb82上執行

[grid@rbdb82 ~]$ ssh rbdb81 date

2013年 11月 5日 星期四 17:28:09 CST

[grid@ rbdb82 ~]$

 

以上若是都不須要密碼那麼互信就行了

 

 

 

 

 

檢查結果：有幾個內核

參數檢測失敗，更改時必須兩個節點都更改

kernel.shmall = 2097152

fs.file-max = 6815744

fs.aio-max-nr = 1048576

 

對於包：（rbdb82可使用scp拷貝rbdb81上面的包）

從新檢查後，剩下swap和DNS的錯誤，swap錯誤如今不能解決，沒有虛擬磁盤了，加盤須要重啓。DNS不須要配置，因此就直接下一步

若是碰到以上問題,就要解決ASM的共享問題,在ASM節中有說明

 

進入安裝光盤安裝

跑腳本時必定要依次跑，第一個在node1跑完成功後，再在node2上跑，第一個在全部節點上都跑完成功後才跑第二個，跑法與第一個相同。跑的時候最好grid用戶登陸後再直接[grid@node1 ~]$ su進入root用戶，這樣能保留grid用戶的環境變量。

5.ORACLE安裝

 

su - oracle

準備環境變量

rbdb81，rbdb82只須要更改sid。（可能在這裏配置sid無效了，最後也會自動加上1和2，就像asm的sid同樣）

vi /home/oracle/.bash_profile

 

ORACLE_BASE=/u01/app/oracle ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1 ORACLE_SID=rbdb81 PATH=$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:$PATH:$HOME/bin LANG=C export PATH ORACLE_BASE ORACLE_HOME ORACLE_SID LANG

 

 

運行runInstaller 開始安裝

./runInstaller

 

 

配置oracle用戶的互信，與GI中的相似

[oracle@node1 ~]$ ssh node2 date

2012年 12月 20日 星期四 19:15:06 CST

[oracle@node2 ~]$ ssh node1 date

2012年 12月 20日 星期四 19:15:13 CST

後面兩個錯誤都是DNS解析的問題，能夠無論。第一個錯誤如今沒有虛擬磁盤，不能解決。直接所有忽略，next

 

 

 

跑腳本，node1跑完成功後再在node2跑

7.ocr鏡像

先用ASM增長一個名爲OCRVOTEMO1的磁盤組,而後按如下完成

[root@rbdb81 rmanbak]# su - grid

[grid@rbdb81 ~]$ ocrcheck

Status of Oracle Cluster Registry is as follows :

     Version                  :          3

     Total space (kbytes)     :262120

     Used space (kbytes)      :       2888

     Available space (kbytes) :     259232

8.日誌組設置

兩邊數據庫啓動時,使用如下腳本在sqlplus / as sysdba 中運行

1,建立4組日誌組,大小爲512M

alter database add logfile thread 1 group 5 '+DATA01' size 512M;

alter database add logfile thread 2 group 6 '+DATA01' size 512M;

alter database add logfile thread 1 group 7 '+DATA01' size 512M;

alter database add logfile thread 2 group 8 '+DATA01' size 512M;

2,切歸檔,切到原來4組不在current狀態

alter system archive log current;

3,刪除原來的日誌組(只有52M,不夠用,刪掉)

alter database drop logfile group 1;

alter database drop logfile group 2;

alter database drop logfile group 3;

alter database drop logfile group 4;

4,增長4組新的日誌組

alter database add logfile thread 1 group 1 '+DATA01' size 512M;

alter database add logfile thread 2 group 2 '+DATA01' size 512M;

alter database add logfile thread 1 group 3 '+DATA01' size 512M;

alter database add logfile thread 2 group 4 '+DATA01' size 512M;

 

9.processes

SQL> show parameter proces

 

NAME                                        TYPE       VALUE

------------------------------------ ----------- ------------------------------

aq_tm_processes                 integer   1

cell_offload_processing               boolean TRUE

db_writer_processes                      integer   4

gcs_server_processes                     integer   3

global_txn_processes                    integer   1

job_queue_processes                     integer   100

log_archive_max_processes    integer   4

processes                        integer   150

processor_group_name            string

SQL> alter system set processes=5000 scope=spfile sid='*';

System altered.

 

10.設置RMAN策略

1, 設置備份爲2份

CONFIGURE RETENTION POLICY TO REDUNDANCY 2;

2,設置控制文件自動備份

CONFIGURE CONTROLFILE AUTOBACKUP ON;

CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/rmanbak/autocontrol/%F';

3,全備腳本

見RMAN備份計劃手冊

 

11.增長靜態監聽

Netca

設置端口

Netmgr(兩節點都要作)

 

12.tnsnames.ore文件

在客服端,HOSTS文件要增長

192.168.1.208  rbdb81

192.168.1.209  rbdb82

192.168.1.210  rbdb8scan

 

 

 

RBSCAN=   (DESCRIPTION =     (ADDRESS_LIST =       (ADDRESS = (PROTOCOL = TCP)(HOST = rbdb8scan)(PORT = 1521))     )     (CONNECT_DATA =       (SERVER = DEDICATED)       (SERVICE_NAME = rbdbon8)     )   )   RBVIP=   (DESCRIPTION =     (ADDRESS_LIST =       (ADDRESS = (PROTOCOL = TCP)(HOST = rbdb81vip)(PORT = 1521))       (ADDRESS = (PROTOCOL = TCP)(HOST = rbdb82vip)(PORT = 1521))     )     (CONNECT_DATA =       (SERVER = DEDICATED)       (SERVICE_NAME = rbdbon8)     )   )     RB55VIP=   (DESCRIPTION =     (ADDRESS_LIST =       (LOAD_BALANCE=ON)       (ADDRESS = (PROTOCOL = TCP)(HOST = rbdb81vip)(PORT = 1555))       (ADDRESS = (PROTOCOL = TCP)(HOST = rbdb82vip)(PORT = 1555))     )     (CONNECT_DATA =       (SERVER = DEDICATED)       (SERVICE_NAME = rbdbon8)     )   )
