AIX版本：AIX 6.1

Oracle版本：Oracle10.2.0.1.0

需要下載的Oracle安裝介質：10gr2_aix5l64_database.cpio

p8202632_10205_AIX64-5L.zip

檢查過程如下，到執行rootpre.sh的時候問題出來了：

有哥們網上裝10203的時候遇到類似的問題，解決！拿出來分享下，至於我的結果是否適合10205，請看下文。 

1.    安裝前的系統補丁檢查：

作業系統版本在AIX 6.1 SP 1 (AIX 6100-00-01)及以上時,確認打上以下APAR補丁：

IZ10223: OLSON TIMEZONE SETTINGS IS NOT WORKING FOR 64BIT APPLICATIONS. APPLIES TO AIX 6100-00

檢查方法：

# instfix -i |grep IZ10223

All filesets for IZ10223 were found.

另，需確認已安裝包bos.adt.libm, bos.adt.prof, bos.cifs_fs.rte

檢查方法：lslpp -l bos.adt.base bos.adt.lib bos.adt.libm bos.perf.perfstat bos.perf.libperfstat bos.perf.proctools bos.adt.prof bos.cifs_fs.rte

# lslpp -l bos.adt.base bos.adt.lib bos.adt.libm bos.perf.perfstat bos.perf.libperfstat bos.perf.proctools bos.adt.prof bos.cifs_fs.rte

2.    當以root使用者執行Oracle 10gR2的“rootpre.sh”時，會顯示AIX AIO的錯誤資訊：

# ./rootpre.sh

./rootpre.sh output will be logged in /tmp/rootpre.out_11-12-31.09:09:02

解決方法：

下載並使用10.2.0.3版本上的patch 6718715（p6718715_10203_AIX64-5L.zip）來替換原來的rootpre目錄。

在解壓p6718715_10203_AIX64-5L.zip檔案時，由於預設AIX安裝是不自帶unzip工具的，所以無法直接解壓zip檔案，這時可以使用Oracle安裝目錄下的unzip工具，具體路徑：

~/Disk1/install/unzip

再執行rootpre.sh後無報錯：

# ./rootpre.sh

./rootpre.sh output will be logged in /tmp/rootpre.out_11-12-31.09:09:47

3.    執行runInstaller時注意事項

Oracle使用者執行runInstaller時需要增加-ignoreSysPrereqs引數：

./runInstaller -ignoreSysPrereqs

同時，在進行Product-Specific Prerequisite Checks時，在Checking operationg system requirements時會由於AIX版本不支援而出現告警。

這時可在核取方塊裡打鉤，使用者自己確認（Status會變為User Verified）。

4.    其他報錯

（1）安裝資料庫的時候，同事發現作業系統的系統時間不對，於是在我安裝前將時間回撥了1天，然後我開始安裝資料庫。在執行runInstaller的時候，出現了以下報錯：

Preparing to launch Oracle Universal Installer from /tmp/OraInstall2011-12-30_02-24-52PM. Please wait ...oracle@fedb_a@/oracle/Disk1 $ Oracle Universal Installer, Version10.2.0.1.0 Production

Copyright (C) 1999, 2005, Oracle. All rights reserved.

touch: cannot change times on /var/opt/freeware/lib/rpm/packages.rpm

rpm_share: 0645-007 ATTENTION: set_time_token() returned an unexpected result.

這個報錯與系統時間調整有關，set_time_token()函式的呼叫返回了非預期結果，不過安裝仍能繼續。考慮到可能有潛在的隱患，最後還是在第二天重新裝了一次資料庫，重灌時報錯已消失。

（2）執行runInstaller安裝時，每次到60%安裝介面就會無反映

檢查了Inventory目錄下的日誌，發現有err結尾的安裝日誌檔案。

cat /oracle/oraInventory/logs/oraInstall2011-12-30_04-42-55PM.err後發現以下報錯：

Caught UnknownHostException: fedb_b: fedb_b

原來是主機名無法解析，查了下系統目前的主機名：fedb_b

再看了下/etc/hosts中的定義，沒有fedb_b的定義，看來這個就是原因了。

將主機名的定義寫到/etc/hosts後，問題解決，安裝正常完成。
