Linux下安裝了Oracle10g後重新啟動的問題

             Linux下安裝了Oracle10g後重新啟動的問題

在Fedora8下安裝了Oracle10g之後，當再次重啟電腦以後！使用"sqlplus system/mileschen"登入系統出現下面的錯誤資訊：
ERROR:
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Linux Error: 2: No such file or directory

解決步驟如下：
用"oracle"使用者登入到系統後，輸入如下命令：
(1)[oracle@localhost ~]$ sqlplus /nolog
 SQL*Plus: Release 10.2.0.1.0 - Production on Fri Dec 26

(2)SQL>connect / as sysdba

這樣代表資料庫常式已經啟動了，然後輸入下面命令登入使用者
(4)[oracle@localhost ~]$ sqlplus system/mileschen
