**Oracle Study之-AIX6.1构建Oracle 11gR2 RAC(1)**

环境：

操作系统： AIX 6100-09（SP3)

Cluster：HACMP6.1

集群软件： GI 11.2.0.1

数据库：   Oracle 11.2.0.1

**构建AIX平台下RAC 依据共享存储的使用方式可以分两种：**

**1、建立基于并发卷组（VG concurrent）的共享存储**

**2、建立基于ASM下的RAW的共享存储**

**        由于本系统阵列（SUN T300）不支持并发存储，不具有reserve\_policy或reserve\_lock属性；所以在使用ASM做并发存储时，其中一个节点访问磁盘后会锁定磁盘，而另外的节点就不能再访问共享盘；所以本次环境是通过HACMP实现并发卷组的共享，然后再通过逻辑卷建立ASM DISKGOUP. 这样整个系统多了hacmp，增加了管理的复杂性。**

系统架构：

**![Center][]**

**本次系统架构为：AIX 6100-09(SP3)+HACMP6.1+ASM+Oracle GI + Oracle 11gR2**

**网络环境：**

**\[root@aix209 /\]\#ifconfig -a**

en2: flags=5e084863,c0<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,CHECKSUM_OFFLOAD(ACTIVE),PSEG,LARGESEND,CHAIN>
            inet 192.168.8.209 netmask 0xffffff00 broadcast 192.168.8.255
    en0: flags=5e084863,c0<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,CHECKSUM_OFFLOAD(ACTIVE),PSEG,LARGESEND,CHAIN>
            inet 10.10.10.209 netmask 0xffffff00 broadcast 10.10.10.255

**\[root@aix210 /\]\#ifconfig -a**

en2: flags=5e084863,c0<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,CHECKSUM_OFFLOAD(ACTIVE),PSEG,LARGESEND,CHAIN>
            inet 192.168.8.210 netmask 0xffffff00 broadcast 192.168.8.255
    en0: flags=5e084863,c0<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,CHECKSUM_OFFLOAD(ACTIVE),PSEG,LARGESEND,CHAIN>
            inet 10.10.10.210 netmask 0xffffff00 broadcast 10.10.10.255

**\[root@aix209 tmp\]\#cat /etc/hosts**

192.168.8.209  aix209
    192.168.8.251  aix209-vip
    10.10.10.209   aix209-priv
    192.168.8.210   aix210
    192.168.8.252   aix210-vip
    10.10.10.210    aix210-priv
    192.168.8.253   rac_scan

\-------- 本次构建不使用DNS Server，所以在hosts文件解析scan ip。

**二、创建配置用户**

**\[root@aix209 /\]\#cat mkuser.sh **

mkgroup -'A' id='1000' adms='root' oinstall 
    mkgroup -'A' id='1020' adms='root' asmadmin 
    mkgroup -'A' id='1021' adms='root' asmdba 
    mkgroup -'A' id='1022' adms='root' asmoper 
    mkgroup -'A' id='1031' adms='root' dba 
    mkgroup -'A' id='1032' adms='root' oper 
    
    mkuser id='1001' pgrp='oinstall' groups='dba,asmdba,asmadmin,oper' home='/home/oracle' oracle 
    mkuser id='1002' pgrp='oinstall' groups='asmadmin,asmdba,asmoper,oper,dba' home='/home/grid' grid

**配置用户：（分配权限、资源配置）**

<strong>[root@aix210 /]#/usr/bin/chuser capabilities=CAP_NUMA_ATTACH,CAP_BYPASS_RAC_VMM,CAP_PROPAGATE grid
    [root@aix210 /]#/usr/bin/chuser capabilities=CAP_NUMA_ATTACH,CAP_BYPASS_RAC_VMM,CAP_PROPAGATE oracle</strong>

**\[root@aix209 /\]\#cat /etc/security/limits**

oracle:
            fsize = -1
            data = -1
            stack = -1
            core = -1
            rss = -1
            nofiles = -1
            threads = -1
            nproc = -1
    
    
    grid:
            fsize = -1
            data = -1
            stack = -1
            core = -1
            rss = -1
            nofiles = -1
            threads = -1
            nproc = -1

**配置用户profile：**

**grid用户：**

**\[grid@aix210 ~\]$cat .profile**

export EDITOR=vi
    export ORACLE_SID=+ASM2
    export ORACLE_BASE=/u01/app/oracle
    export ORACLE_HOME=/u01/grid
    export GRID_HOME=/u01/grid
    export LD_LIBRARY_PATH=$ORACLE_HOME/lib
    export THREADS_FLAG=native
    export PATH=$ORACLE_HOME/bin:/bin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/X11R6/bin
    umask 022

**Oracle 用户:  
\[oracle@aix210 ~\]$cat .profile**

ORACLE_BASE=/u01/app/oracle
    ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
    ORACLE_SID=prod2
    PATH=$PATH:$ORACLE_HOME/bin
    export ORACLE_BASE ORACLE_HOME ORACLE_SID PATH

**三、创建文件系统及目录**

**\[root@aix209 /\]\#cat mkdir.sh**

mkdir -p /u01/app/oracle 
    mkdir -p /u01/grid 
    mkdir -p /u01/app/oraInventory 
    chown -R oracle:oinstall /u01/app/oracle
    chown -R grid:oinstall /u01/grid 
    chown -R grid:oinstall /u01/app/oraInventory 
    chmod -R 775 /u01/
