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：
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）
[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
[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/
