Oracle Io 異常: The Network Adapter could not establish the connection 解決

http://www.iteye.com/problems/47907 謝謝這位大哥-------------未解（win7下）

Exception;如下:

java.sql.SQLException: Io 異常: The Network Adapter could not establish the connection
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:134)
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:179)
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:333)
at oracle.jdbc.driver.OracleConnection.<init>(OracleConnection.java:404)

at java.sql.DriverManager.getConnection(Unknown Source)
at java.sql.DriverManager.getConnection(Unknown Source)
at com.xwl.oracle.db.util.OracleConnection.main(OracleConnection.java:25)

解決代碼:

Class.forName("oracle.jdbc.driver.OracleDriver").newInstance(); 

String addrRAC = "(ADDRESS=(PROTOCOL=TCP)(HOST =10.0.5.62)(PORT =1521))(ADDRESS=(PROTOCOL=TCP)(HOST =10.0.5.60)(PORT =1521))"; 

String url = "jdbc:oracle:thin:@" + "(DESCRIPTION=" 
+ "(ADDRESS_LIST=" + addrRAC + ")" + "(CONNECT_DATA=" 
+ "(SERVER=DEDICATED)" + "(SERVICE_NAME=racdbs)" + ")" 
+ ")"; 

Connection oracn = DriverManager.getConnection(url, "system","qz123456"); 

我的正確代碼:

String addrRAC = "(ADDRESS=(PROTOCOL=TCP)(HOST =192.168.1.100)(PORT =1521))(ADDRESS=(PROTOCOL=TCP)(HOST =192.168.1.100)(PORT =1521))"; 


String url = "jdbc:oracle:thin:@" + "(DESCRIPTION=" 
+ "(ADDRESS_LIST=" + addrRAC + ")" + "(CONNECT_DATA=" 
+ "(SERVER=DEDICATED)" + "(SERVICE_NAME=orcl_xwl)" + ")" 
+ ")";
