在Windows上连接到Oracle数据库

Question

I have two machines on my network:

1. pc-1 is running on Windows XP SP3 , IP 192.168.1.15
2. pc-2 is running on Windows Vista , IP 192.168.1.16

Now I have loaded Oracle 11gR2 on pc-2 (Vista) and the listener is running with the following settings: address=192.168.1.16 and port=1065.

I am trying to connect to Oracle database via pc-1 (XP) using jdbc thin driver but I get the error The network adapter could not establish the connection.
My JDBC url : jdbc:oracle:thin:@192.168.1.16:1065:ora

The pc-2 is reachable, I checked it by ping 192.168.1.16

I tried a few things from PC-1 :

• TELNET 192.168.l.16 1065 gives error Connecting To 192.168.1.16...Could not open connection to the host, on port 1065: Connect failed. The firewall on pc-2 (vista+oracle) is turned off so I don't think firewall is blocking port 1065.

• tnsping 192.168.1.16:1065 gives error TNS-12535: TNS:operation timed out

• sqlplus sys/sys@//192.168.1.16:1065/ora as sysdba but it gives error

  ERROR:ORA-12170: TNS:Connect timeout occurred

Some of the commands output on PC-2

• netstat -a

LOCAL ADDRESS ------------ FOREIGN ADDRESS -------------- STATE
192.168.1.16:1065----------------- PCNAME -------------------LISTENING

Can anyone please specify in details what shall I do? I am trying to do this first time so no idea about what is going wrong?

Answer 1

You have to give the proper SID details in the tnsnames.ora file located under

for Linux: /home/oracle/oracle/product/10.2.0/db_1/network/admin/tnsnames.ora

Answer 2

You don't say how you're connecting - I am assuming through TNS?

Did you specify the port of 1065 in your TNSNAMES.ORA file on the XP system?

Can you connect from your XP system using EZCONNECT? That takes tnsnames.ora out of the equation.

sqlplus user/pw@//192.168.1.16:1065/db_name

Answer 3

ERROR:ORA-12170: TNS:Connect timeout occurred

this error usually means failure network connection

It's simple

shut down your windows firewall
