安裝Oracle 10.2.0.5 RAC for AIX6（一）

首先檢查兩個節點的硬體情況：

# /usr/sbin/lsattr -E -l sys0 -a realmem
realmem 65011712 Amount of usable physical memory in Kbytes False
# /usr/sbin/lsps -a

64

然後檢查兩個節點上系統軟體版本和包的安裝情況：

# oslevel -r
6100-06
# lslpp -l bos.adt.base bos.adt.lib bos.adt.libm bos.perf.perfstat bos.perf.libperfstat bos.perf.proctools rsct.basic.rte

下面在節點1上建立oinstall和dba組，然後利用smit security建立oracle使用者：

# /bin/mkgroup oinstall
# /bin/mkgroup dba
# smit security

在建立oracle使用者時指定oinstall和dba組選項。在Primary GROUP處輸入oinstall，在Group SET處輸入dba。

# id oracle
uid=203(oracle) gid=202(oinstall) groups=203(dba)
# passwd oracle
Changing password for "oracle"
oracle's New password:
Enter the new password again:
# id nobody
uid=4294967294(nobody) gid=4294967294(nobody)

確認oracle使用者組選項正確，修改oracle密碼，並確認nobody使用者存在。

修改oracle使用者的.profile檔案，新增下面的內容：

ORACLE_SID=ywdb1
export ORACLE_SID
ORACLE_BASE=/opt/oracle
export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/10.2/database
export ORACLE_HOME
ORA_CRS_HOME=$ORACLE_BASE/product/10.2/crs
export ORA_CRS_HOME
PATH=$ORACLE_HOME/bin:$ORA_CRS_HOME/bin:$PATH
export PATH
DISPLAY=10.142.195.119:0.0
export DISPLAY

設定oracle使用者和root使用者的屬性：

# smit chuser

將Soft FILE size、Soft CPU time、Soft DATA segment和Soft STACK size都設定為沒有限制，也就是-1。

# smit chgsys

設定系統引數，將Maximum number of PROCESSES allowed per user引數的值設定超過2048。

# /usr/sbin/no -a | more

# /usr/sbin/lsattr -E -l sys0 -a pre520tune
pre520tune disable Pre-520 tuning compatibility mode True
# /usr/sbin/no -o udp_sendspace=65536
Setting udp_sendspace to 65536
Change to tunable udp_sendspace, will only be effective for future connections
# /usr/sbin/no -o udp_recvspace=655360
Setting udp_recvspace to 655360
Change to tunable udp_recvspace, will only be effective for future connections
# /usr/sbin/no -o tcp_sendspace=65536
Setting tcp_sendspace to 65536
Change to tunable tcp_sendspace, will only be effective for future connections
# /usr/sbin/no -o tcp_recvspace=65536
Setting tcp_recvspace to 65536
Change to tunable tcp_recvspace, will only be effective for future connections
# /usr/sbin/no -o rfc1323=1
Setting rfc1323 to 1
Change to tunable rfc1323, will only be effective for future connections
# /usr/sbin/no -o sb_max=1310720
Setting sb_max to 1310720
# /usr/sbin/no -r -o ipqmaxlen=512
Setting ipqmaxlen to 512 in nextboot file
Warning: changes will take effect only at next reboot

透過no –a，檢查系統網路引數配置，其中udp和tcp引數設定應和上面修改的配置保持一致，rfc1323、sb_max以及ipqmaxlen也同樣仿照上面的例子進行設定。

在/etc/rc.net中新增下面的內容：

if [ -f /usr/sbin/no ] ; then
/usr/sbin/no -o udp_sendspace=65536
/usr/sbin/no -o udp_recvspace=655360
/usr/sbin/no -o tcp_sendspace=65536
/usr/sbin/no -o tcp_recvspace=65536
/usr/sbin/no -o rfc1323=1
/usr/sbin/no -o sb_max=1310720
/usr/sbin/no -r -o ipqmaxlen=512
fi

檢查主機名稱、IP地址資訊：

# hostname
ywdb1
# ifconfig -a
en0: flags=5e080863,c0
inet 10.142.195.5 netmask 0xffffff00 broadcast 10.142.195.255
tcp_sendspace 131072 tcp_recvspace 65536 rfc1323 0
en12: flags=5e080863,c0
inet 192.168.195.1 netmask 0xffffff00 broadcast 192.168.195.255
tcp_sendspace 131072 tcp_recvspace 65536 rfc1323 0
lo0: flags=e08084b,c0
inet 127.0.0.1 netmask 0xff000000 broadcast 127.255.255.255
inet6 ::1%1/0
tcp_sendspace 131072 tcp_recvspace 131072 rfc1323 1

下面設定兩個節點的/etc/hosts檔案：

10.142.195.5 ywdb1

10.142.195.6 ywdb2

10.142.195.1 ywdb1-vip

10.142.195.2 ywdb2-vip

192.168.195.1 ywdb1-priv

192.168.195.2 ywdb2-priv

在兩個節點的oracle目錄下，建立.rhosts檔案，新增下列內容：

ywdb1
ywdb2
ywdb1-vip
ywdb2-vip
ywdb1-priv
ywdb2-priv

最後建立cluster和db安裝對應的目錄，安裝準備工作完成。
