我的電腦是32位的win7家庭版系統，那麼這樣的系統能不能裝上oracle呢？能的！就是可能會出錯，在裝oracle時，每個人遇到的問題都不同，有的人裝了雙系統，有的人重做了系統，真心酸，先讓電腦斷網（不論是無線還是有線）再裝oracle（據說是因為oracle會記住當時的網絡配置,下次再開機環境變了，就連不上了，但我覺得關系不大，我裝了兩次，一次連網，一次斷網，結果都一樣，無法連接到數據庫實例）,我按照教程裝好了後，立刻打開OEM能打開，但是下次開機就是無法連接到數據庫實例，真的！！！剛開始好用，下次不好用！！而打不開OEM,SQLDeveloper也別想打開！我弄了一周，就在下決心裝雙系統的前一天，被我解決了，現在整理解決辦法如下，希望有更多同胞能順利裝上oracle,邁出第一步
就是這個問題 Enterprise Manager無法連接到數據庫實例 ！！

就如圖中所示把localhost改成THINK-THINK，其它不動，如果在修改時沒有權限，無法保存，就先把它復制到D盤修改，再復制回去就好了
2修改./app/oracle/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora
我的tnsnames.ora 如下：
# tnsnames.ora Network Configuration File: C:\myoracle\think\product\11.2.0\dbhome_2\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.
NEWDB =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = newdb)
)
)
ORACLR_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
(CONNECT_DATA =
(SID = CLRExtProc)
(PRESENTATION = RO)
)
)
也改成主機名即可，其它不動，newdb是我的數據庫SID名
3.重啟監聽器
以管理員的身份運行 cmd,就是在開始菜單輸入cmd搜索，出結果後，右鍵以管理員身份運行cmd
先輸入
lsnrctl stop
再輸入
lsnrctl start
重啟完監聽器後，剛才的配置就生效了，注意以後每次開機都要運行這兩個命令，lsnrctl stop lsnrctl start 才能打開OEM和SQLDevloper，沒辦法，否則每次都是無法連接到實例，但是改配置文件只要一次！
成功了！撒花
