This question came from our site for professional and enthusiast programmers.

You need to change port 1158 to 1521 in your connection properties.

Oracle's listener for database connections runs on port 1521 by default.

Port 1158 is the web listener for Database Control, a webgui for managing the database.

In addition, the servicename should be something like "", or you can try using SID and specifying ORCL.

check if Navicat is configured : Tools/Options/Miscellaneous/OCI see

use the port from the installation and as ServiceName "XE":

Server Type: Oracle Connection Name: Oracle 11g XE Connection Type: Basic Host Name/IP Address: localhost Port: 1521 Service Name: XE User Name: SYSTEM Save Password: True

That worked for me :-)

Cheers! Martin
