这个只是笔记,防止丢失,没事见整理

在vmware安装目录 创建磁盘:

vmware-vdiskmanager.exe -c -s 1000Mb -a lsilogic -t 2 D:\VMWARE\racsharedisk\ocr.vmdk

vmware-vdiskmanager.exe -c -s 1000Mb -a lsilogic -t 2 D:\VMWARE\racsharedisk\ocr2.vmdk

vmware-vdiskmanager.exe -c -s 1000Mb -a lsilogic -t 2 D:\VMWARE\racsharedisk\votingdisk.vmdk

Oracle_sid需要根据节点不同进行修改 

[root@rac1 ~]# su - grid 

[grid@rac1 ~]$ vi .bash_profile


export TMP=/tmp

export TMPDIR=$TMP

export ORACLE_SID=+ASM1

export ORACLE_BASE=/u01/app/grid

export ORACLE_HOME=/u01/app/11.2.0/grid

export PATH=/usr/sbin:$PATH

export PATH=$ORACLE_HOME/bin:$PATH

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib

export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

umask 022




##rac1:

export TMP=/tmp

export TMPDIR=$TMP

export ORACLE_SID=+ASM1

export ORACLE_BASE=/u01/app/grid

export ORACLE_HOME=/u01/app/11.2.0/grid

export PATH=/usr/sbin:$PATH

export PATH=$ORACLE_HOME/bin:$PATH

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib

export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

umask 022



##rac2:


export TMP=/tmp

export TMPDIR=$TMP

export ORACLE_SID=+ASM2

export ORACLE_BASE=/u01/app/grid

export ORACLE_HOME=/u01/app/11.2.0/grid

export PATH=/usr/sbin:$PATH

export PATH=$ORACLE_HOME/bin:$PATH

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib

export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

umask 022



需要注意的是ORACLE_UNQNAME是数据库名,创建数据库时指定多个节点是会创建多个实例,ORACLE_SID指的是数据库实例名



[root@rac1 ~]# su - oracle 

[oracle@rac1 ~]$ vi .bash_profile



#rac1:

export TMP=/tmp

export TMPDIR=$TMP

export ORACLE_SID=orcl1 

export ORACLE_UNQNAME=orcl

export ORACLE_BASE=/u01/app/oracle

export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1

export TNS_ADMIN=$ORACLE_HOME/network/admin

export PATH=/usr/sbin:$PATH

export PATH=$ORACLE_HOME/bin:$PATH

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib



##rac2:

export TMP=/tmp

export TMPDIR=$TMP

export ORACLE_SID=orcl2

export ORACLE_UNQNAME=orcl

export ORACLE_BASE=/u01/app/oracle

export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1

export TNS_ADMIN=$ORACLE_HOME/network/admin

export PATH=/usr/sbin:$PATH

export PATH=$ORACLE_HOME/bin:$PATH

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib




$ source .bash_profile使配置文件生效





配置 绕城rac1 rac2 中的 root  grid   oracle  直接相互无ssh访问

每一个用户目录下都要配置:


ssh-keygen -t rsa

ssh rac1 cat ~/.ssh/id_rsa.pub >> authorized_keys

ssh rac2 cat ~/.ssh/id_rsa.pub >> authorized_keys

scp authorized_keys rac2:~/.ssh/


ssh rac1 date

ssh rac2 date

ssh rac1-priv date

ssh rac2-priv date



##如果swap太小,swap调整方法:


通过此种方式进行swap 的扩展,首先要计算出block的数目。具体为根据需要扩展的swapfile的大小,以M为单位。block=swap分区大小*1024, 例如,需要扩展64M的swapfile,则:block=64*1024=65536.


然后做如下步骤:


dd if=/dev/zero of=/swapfile bs=1024 count=9216000

#mkswap /swapfile 

#swapon /swapfile 

#vi /etc/fstab 

增加/swapf swap swap defaults 0 0 

# cat /proc/swaps 或者# free –m //查看swap分区大小 

# swapoff /swapf //关闭扩展的swap分区




共享磁盘配置:


rac1 和rac2配置共享磁盘 (esxi主机上面 2个总线都要选择共享才不会报错):

rac2 需要重启才可以在 ll /dev/raw 下面看到磁盘

所以只需root.sh 的时候 如果报错找不到raw磁盘,需要重启rac2,所以在配置好共享磁盘之后,重启rac2

在rac1格式化之后,

cat /etc/udev/rules.d/60-raw.rules 

# Enter raw device bindings here.

#

# An example would be:

#   ACTION=="add", KERNEL=="sda", RUN+="/bin/raw /dev/raw/raw1 %N"

# to bind /dev/raw/raw1 to /dev/sda, or

#   ACTION=="add", ENV{MAJOR}=="8", ENV{MINOR}=="1", RUN+="/bin/raw /dev/raw/raw2 %M %m"

# to bind /dev/raw/raw2 to the device with major 8, minor 1.

ACTION=="add",KERNEL=="/dev/sdb1",RUN+='/bin/raw /dev/raw/raw1 %N"

ACTION=="add",ENV{MAJOR}=="8",ENV{MINOR}=="17",RUN+="/bin/raw /dev/raw/raw1 %M %m"

ACTION=="add",KERNEL=="/dev/sdc1",RUN+='/bin/raw /dev/raw/raw2 %N"

ACTION=="add",ENV{MAJOR}=="8",ENV{MINOR}=="33",RUN+="/bin/raw /dev/raw/raw2 %M %m"

ACTION=="add",KERNEL=="/dev/sdd1",RUN+='/bin/raw /dev/raw/raw3 %N"

ACTION=="add",ENV{MAJOR}=="8",ENV{MINOR}=="49",RUN+="/bin/raw /dev/raw/raw3 %M %m"

ACTION=="add",KERNEL=="/dev/sde1",RUN+='/bin/raw /dev/raw/raw4 %N"

ACTION=="add",ENV{MAJOR}=="8",ENV{MINOR}=="65",RUN+="/bin/raw /dev/raw/raw4 %M %m"

ACTION=="add",KERNEL=="/dev/sdf1",RUN+='/bin/raw /dev/raw/raw5 %N"

ACTION=="add",ENV{MAJOR}=="8",ENV{MINOR}=="81",RUN+="/bin/raw /dev/raw/raw5 %M %m"


KERNEL=="raw[1-5]",OWNER="grid",GROUP="asmadmin",MODE="660"



注意ENV{MINOR} 的值相差16,增加的值也得相差16 要不然识别不出来

然后执行 start_udev

ll /dev/raw



rac2上要是没有 执行 partprobe


[root@rac2 ~]# sh /tmp/CVU_11.2.0.4.0_grid/runfixup.sh

解决方法竟然是出现pa user cert的时候在另一个窗口不停的执行下面的命令,直到命令执行成功,真是变态啊。


##执行root.sh 的时候 出现 adding demo to inttab的时候 执行,要不然可能需要重现安装系统来安装rac

/bin/dd if=/var/tmp/.oracle/npohasd of=/dev/null bs=1024 count=1



错误:

ORA-12545: Connect failed because target host or object does not exist

解决:

经测试,其实只需要在客户端主机的/etc/hosts文件中,添加目标数据库的vip的解决信息便可以解决(测试数据库版本11G R2)


RAC维护


在工作上有时候忘记ASM磁盘组所对应的ASM磁盘和设备名,需要查看时可以在ASM实例中使用以下命令:

SQL> select name,path from v$asm_disk_stat;


1.查看服务状态


忽略gsd问题


[root@rac1 ~]# su - grid

[grid@rac1 ~]$ crs_stat -t


检查集群运行状态 

[grid@rac1 ~]$ srvctl status database -d orcl 

Instance orcl1 is running on node rac1 

Instance orcl2 is running on node rac2



检查本地节点的CRS状态


[grid@rac1 ~]$ crsctl check crs

CRS-4638: Oracle High Availability Services is online

CRS-4537: Cluster Ready Services is online

CRS-4529: Cluster Synchronization Services is online

CRS-4533: Event Manager is online

检查集群的CRS状态


[grid@rac1 ~]$ crsctl check cluster

CRS-4537: Cluster Ready Services is online

CRS-4529: Cluster Synchronization Services is online

CRS-4533: Event Manager is online

3.查看集群中节点配置信息


[grid@rac1 ~]$ olsnodes

rac1

rac2


[grid@rac1 ~]$ olsnodes -n

rac1    1

rac2    2


[grid@rac1 ~]$ olsnodes -n -i -s -t

rac1    1       rac1-vip        Active  Unpinned

rac2    2       rac2-vip        Active  Unpinned

4.查看集群件的表决磁盘信息


[grid@rac1 ~]$ crsctl query css votedisk

##  STATE    File Universal Id                File Name Disk group

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

 1. ONLINE   496abcfc4e214fc9bf85cf755e0cc8e2 (/dev/raw/raw1) [OCR]

Located 1 voting disk(s).

5.查看集群SCAN VIP信息


[grid@rac1 ~]$ srvctl config scan

SCAN name: scan-ip, Network: 1/192.168.248.0/255.255.255.0/eth0

SCAN VIP name: scan1, IP: /scan-ip/192.168.248.110

查看集群SCAN Listener信息


[grid@rac1 ~]$ srvctl config scan_listener

SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1521

6.启、停集群数据库


整个集群的数据库启停 

进入grid用户 

[grid@rac1 ~]$ srvctl stop database -d orcl 

[grid@rac1 ~]$ srvctl start database -d orcl


关闭所有节点 

进入root用户 

关闭所有节点 

[root@rac1 bin]# pwd 

/u01/app/11.2.0/grid/bin 

[root@rac1 bin]# ./crsctl stop crs 

实际只关闭了当前结点


EM管理


oracle用户下执行


[oracle@rac1 ~]$ emctl status dbconsole

[oracle@rac1 ~]$ emctl start dbconsole

[oracle@rac1 ~]$ emctl stop dbconsole

本地sqlplus连接


windows中安装oracle客户端版 

修改tsnames.ora 

D:\develop\app\orcl\product\11.2.0\client_1\network\admin\tsnames.ora 

添加


RAC_ORCL =

    (DESCRIPTION =

      (ADDRESS_LIST =

        (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.248.110)(PORT = 1521))

      )

      (CONNECT_DATA =

        (SERVER = DEDICATED)

        (SERVICE_NAME = orcl)

      )

    )

这里的HOST写的是scan-ip


C:\Users\sxtcx>sqlplus sys/oracle@RAC_ORCL as sysdba


SQL*Plus: Release 11.2.0.1.0 Production on 星期四 4月 14 14:37:30 2016


Copyright (c) 1982, 2010, Oracle.  All rights reserved.



连接到:

Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production

With the Partitioning, Real Application Clusters, Automatic Storage Management, OLAP,

Data Mining and Real Application Testing options


SQL> select instance_name, status from v$instance;


INSTANCE_NAME                    STATUS

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

orcl1                            OPEN

当开启第二个命令行窗口连接时,发现实例名为orcl2,可以看出,scan-ip的加入可以具有负载均衡的作用。






oracle环境变量引起的“connected to an idle instance” 



解决查看oracle的环境变量


将ORACLE_SID 和 ORACLE_UNQNAME 都改成自己建立的实例(rac1  rac2)都要改


source 一下 就可以了




asm 增加磁盘:

grid 用户下:

sqlplus / as sysasm


alter diskgroup FRA add disk '/dev/raw/raw4' rebalance power 5;


集群关闭和开启:

 oracle 11g RAC 启动和关闭和一些维护命令 2013-10-27 16:47:33

分类: Linux

启动和关闭是经常使用的操作,必须牢记,以下整理的文档:

集群名称 rac-cluster 

集群数据库  RACDB

一 关闭rac

1,确认srvctl 和ps -ef|grep smon

[grid@rac1 ~]$ srvctl status database -d RACDB

实例 RACDB1 正在节点 rac1 上运行

实例 RACDB2 正在节点 rac2 上运行

[grid@rac1 ~]$ ps -ef|grep smon

oracle    3676     1  0 06:05 ?        00:00:02 ora_smon_RACDB1

grid     12840     1  0 01:54 ?        00:00:00 asm_smon_+ASM1

grid     27890 27621  0 07:52 pts/3    00:00:00 grep smon

2,将数据库关闭并再次确认

[grid@rac1 ~]$ srvctl stop database -d RACDB

[grid@rac1 ~]$  ps -ef|grep smon

3,使用root 帐号关闭ASM

[grid@rac1 ~]$ su -

口令:

[root@rac1 ~]# cd /home/grid

[root@rac1 grid]# sh .bash_profile

4,使用crs_stat 确认集群各项资源和服务运行状态

[root@rac1 bin]# /u01/app/11.2.0/grid/bin/crs_stat -t -v

5,使用crsctl 指令关闭集群

[root@rac1 bin]# /u01/app/11.2.0/grid/bin/crsctl stop cluster -all

6,使用crs_stat 确认集群各项资源和服务运行状态

[root@rac1 bin]# /u01/app/11.2.0/grid/bin/crs_stat -t -v

[root@rac2 ~]# /u01/app/11.2.0/grid/bin/crs_stat -t -v

CRS-0184: Cannot communicate with the CRS daemon.

 说明顺利关闭


二 。RAC 开启

1,root 执行grid 下面的环境变量 (可以不执行直接到/u01/app/11.2.0/grid/bin/模式下)

2,[root@rac1 ~]# /u01/app/11.2.0/grid/bin/crsctl stop cluster -all

3,开启集群

  [root@rac1 ~]# /u01/app/11.2.0/grid/bin/crsctl start cluster -all

  检查状态

  [root@rac2 ~]# /u01/app/11.2.0/grid/bin/crs_stat -t -v

4,使用srvcel 确认数据库状态

 [root@rac1 ~]# /u01/app/11.2.0/grid/bin/srvctl status database -d RACDB

实例 RACDB1 没有在 rac1 节点上运行

实例 RACDB2 没有在 rac2 节点上运行

5,打开RAC 

[root@rac1 ~]# /u01/app/11.2.0/grid/bin/srvctl start database -d RACDB

 确认状态

[root@rac2 ~]# /u01/app/11.2.0/grid/bin/srvctl status database -d RACDB

实例 RACDB1 正在节点 rac1 上运行

实例 RACDB2 正在节点 rac2 上运行

 

6,打开OEM
