這是我們子公司的資料庫系統，因為已經很早就過了伺服器的保固期間，
而且該型號也已無零件備料可供替換，只好將它更換。
順便也將DB由9.2.0.1 32bit 升到 9.2.0.4 64bit
升級的方法很傳統，先安裝 Oracle Enterprise Linux 4.8 64bit，再安裝Oracle 9.2.0.4 64bit
以舊機將資料export出來，再import到新機器上面，最後設定備份腳本，測試時出現錯誤：
[oracle@sent02 oracle]$ ./exp.sh

這是因為Oracle DB是從9.2.0.1昇級到9.2.0.4，某些EXP需要的字典没有被升级所以造成錯誤，
解決方法與9.2.0.4昇級到.2.0.7一樣，執行 rdbms/admin/catexp.sql 就可以了
