1、安裝Oracle客戶端（注意，PLSQL只支持32位的Oracle的客戶端，64系統使用32客戶端的Oracle也沒問題）

直接軟件安裝，直接下一步dao結束即可
2、配置文件配置
1 # tnsnames.ora Network Configuration File. 2 # Generated by Oracle InstantClient tools. 3 # For more information, please visit: http://www.oracle.com/technetwork/database/features/instant-client/index-100365.html 4 5 # Sample: 6 #DatabaseName = 7 # (DESCRIPTION = 8 # (ADDRESS_LIST = 9 # (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521)) 10 # ) 11 # (CONNECT_DATA = 12 # (SERVER = DEDICATED) 13 # (SERVICE_NAME = ServiceName) 14 # (INSTANCE_NAME = InstanceName) 15 # ) 16 # ) 17 18 # Modify the following content to fit your own needs. 19 DummyDatabase = 20 (DESCRIPTION = 21 (ADDRESS_LIST = 22 (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521)) 23 ) 24 (CONNECT_DATA = 25 (SERVER = DEDICATED) 26 (SERVICE_NAME = DummyService) 27 ) 28 ) 29 OSS = 30 (DESCRIPTION = 31 (ADDRESS_LIST = 32 (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.9.73)(PORT = 1521)) 33 ) 34 (CONNECT_DATA = 35 (SERVER = DEDICATED) 36 (SERVICE_NAME = oss) 37 ) 38 ) 39 MAILP3 = 40 (DESCRIPTION = 41 (ADDRESS_LIST = 42 (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.9.41)(PORT = 1521)) 43 ) 44 (CONNECT_DATA = 45 (SERVER = DEDICATED) 46 (SERVICE_NAME = mailp3) 47 ) 48 )
字段解釋：
MAILP3：對應你數據庫服務器名
PROTOCOL：客戶端與服務器端通訊的協議，一般為TCP，該內容一般不用改。
HOST：服務器所在的IP地址
PORT：端口號
SERVICE_NAME：服務名
3、PL/SQ里面配置
選擇首選項，選擇配置項，對應路徑如下
PLSQL加載配置
結果：可以看到數據庫有對應的MAILP3，成功
