篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了oracle 11g rac 笔记（VMware 和esxi主机都可以使用）相关的知识，希望对你有一定的参考价值。
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
vmware-vdiskmanager.exe -c -s 20000Mb -a lsilogic -t 2 D:\VMWARE\racsharedisk\data2.vmdk
vmware-vdiskmanager.exe -c -s 10000Mb -a lsilogic -t 2 D:\VMWARE\racsharedisk\backup.vmdk
编辑rac1 rac2 的vmx文件 添加：

Oracle_sid需要根据节点不同进行修改
[[email protected] ~]# su - grid
[[email protected] ~]$ 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 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
[[email protected] ~]# su - oracle
[[email protected] ~]$ 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

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

asmsnmp 密码 DENG19891220
oracle 密码 deng19891220
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$asm_disk_stat;
1.查看服务状态
忽略gsd问题
[[email protected] ~]# su - grid
[[email protected] ~]$ crs_stat -t
检查集群运行状态
[[email protected] ~]$ 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
[[email protected] ~]$ 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
[[email protected] ~]$ 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
[[email protected] ~]$ olsnodes
rac1
rac2
[[email protected] ~]$ olsnodes -n
rac1 1
rac2 2
[[email protected] ~]$ 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
[[email protected] ~]$ 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
[[email protected] ~]$ 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
[[email protected] ~]$ 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
[[email protected] ~]$ srvctl stop database -d orcl
[[email protected] ~]$ srvctl start database -d orcl
关闭所有节点
进入root用户
关闭所有节点
[[email protected] bin]# pwd
/u01/app/11.2.0/grid/bin
[[email protected] bin]# ./crsctl stop crs
实际只关闭了当前结点
EM管理
oracle用户下执行
[[email protected]1 ~]$ emctl status dbconsole
[[email protected] ~]$ emctl start dbconsole
[[email protected] ~]$ 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/[email protected]_ORCL as sysdba
SQL*Plus: Release 11.2.0.1.0 Production on 星期四 4月 14 14:37:30 2016

SQL> select instance_name, status from v$instance;
INSTANCE_NAME STATUS
-------------------------------- ------------------------
orcl1 OPEN
当开启第二个命令行窗口连接时，发现实例名为orcl2，可以看出，scan-ip的加入可以具有负载均衡的作用。
oracle环境变量引起的“connected to an idle instance”
解决查看oracle的环境变量
将ORACLE_SID 和 ORACLE_UNQNAME 都改成自己建立的实例（rac1 rac2）都要改
source 一下 就可以了
asm 增加磁盘：
grid 用户下：
sqlplus / as sysasm
alter diskgroup FRA add disk ‘/dev/raw/raw4‘ rebalance power 5;
集群关闭和开启：
oracle 11g RAC 启动和关闭和一些维护命令 2013-10-27 16:47:33
分类： Linux
启动和关闭是经常使用的操作，必须牢记，以下整理的文档：
集群名称 rac-cluster
集群数据库 RACDB
一 关闭rac
1，确认srvctl 和ps -ef|grep smon
[[email protected] ~]$ 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
[[email protected] ~]$ 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
[[email protected] ~]$ srvctl stop database -d RACDB
[[email protected] ~]$ ps -ef|grep smon
3,使用root 帐号关闭ASM
[[email protected] ~]$ su -
口令：
[[email protected] ~]# cd /home/grid
[[email protected] grid]# sh .bash_profile
4，使用crs_stat 确认集群各项资源和服务运行状态
[[email protected] bin]# /u01/app/11.2.0/grid/bin/crs_stat -t -v
5，使用crsctl 指令关闭集群
[[email protected] 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
[[email protected] bin]# /u01/app/11.2.0/grid/bin/crs_stat -t -v
[[email protected] ~]# /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，[[email protected] ~]# /u01/app/11.2.0/grid/bin/crsctl stop cluster -all
3，开启集群
[[email protected] ~]# /u01/app/11.2.0/grid/bin/crsctl start cluster -all
检查状态
[[email protected] ~]# /u01/app/11.2.0/grid/bin/crs_stat -t -v
4，使用srvcel 确认数据库状态
[[email protected] ~]# /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
[[email protected] ~]# /u01/app/11.2.0/grid/bin/srvctl start database -d RACDB
确认状态
[[email protected] ~]# /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
[[email protected] ~]# /u01/app/11.2.0/grid/bin/emctl start RACDB
