Install Oracle 11g missing package pdksh-5.2.14 issue

RHEL6 安裝 Oracle 11g 遭遇 pdksh-5.2.14 不存在
http://blog.roodo.com/oraksumi/archives/41081323.html

原因在於 OUI 在進行環境檢查時執行的是下列 command :
----------------------------------------------------------------------------------------
/bin/rpm -q --qf %{version} redhat-release
----------------------------------------------------------------------------------------
在 RHEL6 的環境下 redhat-release 已經被取代為 redhat-release-server-6Server，因此上述 command 會造成了缺少 "elfutils-libelf-devel-0.97" 或是 "pdksh-5.2.14" Package 的錯誤。

解決方式於安裝介質目錄下 database/stage/cvu/cv/admin 找出 cvu_config 這個檔案並且編輯他，將其中的 CV_ASSUME_DISTID=OEL4 改為 CV_ASSUME_DISTID=OEL6 ，如此一來 OUI 便可以正確的檢查系統所需的 Package 了。

由於 "elfutils-libelf-devel-0.97" 或是 "pdksh-5.2.14" 這兩個 Package 並不是必要的，若不想更動 cvu_config 這個檔案，那麼在安裝過程中忽略這個錯誤就可以了。

Migrate Java of IHS 8 from 1.6 to 1.8

1. Can't directly migrate to Java 1.8 before fixpack 8.5.5.11

2. Must new install IHS 8.5.5.11 to have Java 1.8

4. To install IHS 8.5.5.11 with Java 1.8 using imcl command, you must add "-properties wasjava=java8" option

5. Will be able to migrate to 1.8 directly by applying fixpack 8.5.5.12

6. The incorrect core runtime  information in the versionInfo output will be fixed in fixpack 8.5.5.12 (PI77304)

Installing Java SDK 8.0 on WAS 8.5.5.x

7. If you install IHS 5.5.5.11 (new install) using IM GUI (wizard mode), it will install Java 8 default (same as WAS). It is not necessary to add the option "-properties wasjava=java8" like imcl command line.
