1.下載安裝OracleXE
2.檢查oracleXE和TNS服務(wù)是否啟動 （若TNS無法啟動，則檢查環(huán)境變量的ORACLE_HOME，修改為oracle安裝目錄）
3.配置好listener.ora，tnsnames.ora
4.配置好環(huán)境變量TSN_ADMIN，NLS_LANG，ORACLE_HOME等
5.常見問題
(1) ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
解決：startup
（2）執(zhí)行startup時又報錯：
SQL> startup
ORA-01078: failure in processing system parameters
ORA-01565: error in identifying file 'C:\oraclexe\app\oracle\product\11.2.0\server\dbs/spfileXE.ora'
ORA-27041: unable to open file
OSD-04002: unable to open file
O/S-Error: (OS 2) The system cannot find the file specified.
原因：dbs目錄下缺少spfileXE.ora
解決：create spfile='D:\oraclexe\app\oracle\product\11.2.0\server\dbs/spfileXE.ora' FROM pfile='D:\oraclexe\app\oracle\product\11.2.0\server\config\scripts\init.ora';

（3）處理完以上兩部后，執(zhí)行SQL> startup 又有報錯：ORA-00205: ?????????, ??????, ???????
