Status Failure - Test Failed Io Error Connection Reset
a minute: Sign up Oracle SQL Developer: Failure - Test failed: The Network Adapter could not establish the connection? up vote 3 down vote favorite 1 Problem Please note that I changed details for security purposes. However, the problem remains intact. I installed an Oracle 11g database on a server at location, say, herp-devDV.derp.edu. Now I have another Oracle 11g database network adapter could not establish the connection oracle 12c on a server at location, say, derp-db.derp.edu. I entered the connection name, username, password, hostname, and service name in Oracle SQL developer for both herp-devDV.derp.edu and derp-db.derp.edu. I can connect to schema in derp-db.derp.edu, but not herp-devDV.derp.edu. It gives me this message: Failure - Test failed: The Network Adapter could not establish the connection Details I have the following information: Port 1521 is not open for either server when I telnet My listener is up and running for both. I can access derp-db.derp.edu on Oracle SQL Developer. Oracle client is on my local machine + Oracle SQL Developer I can remote desktop to both servers What I have done Googled Stackoverflow Ran stop and start lnrctl commands On herp-devDB.derp.edu I ran lsnrctl status I received the following output Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1521))) STATUS of the LISTENER ------------------------ Alias LISTENER Version TNSLSNR for 64-bit Windows: Version 11.2.0.1.0 - Production Start Date 03-JUN-2014 13:37:22 Uptime 6 days 0 hr. 53 min. 4 sec Trace Level off Security ON: Local OS Authentication SNMP OFF Listener Parameter File D:\oracle\product\11.2.0\dbhome_1\network\admin\listener.ora Listener Log File d:\oracle\diag\tnslsnr\HERP-DEVDB\listener\alert\log.xml Listening Endpoints Summary...

hr_orclusername: hrPassword: hrconnection type: basicport: 1521SID: xeresults:Status: failure-Test failed: IO Error: The network adapter could not establish the connectionCan someone help?No matter which edition of Oracle database you're using or where the database is installed http://www.asktheoracle.net/oracle-xe-database-connection-test-status-failure-test-failed-io-error-the-network-adapter-could-not-establish-the-connection.html (on the same pc as SQL Developer or on a remote server), there are 4 things you need to know when creating a connection from Oracle SQL Developer:the usernamethe passwordthe hostname (i.e. the name of the machine where the database has been installed)the port that the database listener is using to "listen" for connection attemptsand either the Oracle SID or the service name.If you have Oracle Database eXpress Edition (XE) installed locally sql developer then things are much simpler: the username, password, sid and service name should all be the same - XE. That just leaves the host name and the port. Again if installed locally the hostname is most likely to be "localhost" without the quotes or you can use the ip address 127.0.0.1 and the port is most likely to be 1521.However you can check most of these details quite easily. To check the network adapter could hostname, open a command window and type "ping localhost", that should result in several messages starting with "Reply from" being displayed.In the same window you enter "tnsping xe" to check that the service name is recognized. Included in the response will be the service name and the port followed by "OK" if the service name is recognized. Oracle XE also provides another way to check the setting - use the provided Oracle Application Express (APEX) "Get Started" application which you can access from the Windows start menu (from the Oracle Database Express group). This brings up a login page on which you can login as system and then navigate to the Administration -> About Database page. That will confirm the database name.Having checked the service name/sid, port and hostanme and that there is a network connection to the database (via the Oracle utility TNSPING) if you still can't connect using SQL Developer, then start SQL*Plus from the Oracle Database Express group on the Windows start menu and enter "connect / as sysdba" to connect to the database and query dba_users to ensure that HR is a user. You can only use "connect / as sysdba" if you are logged in as the database owner (usually Oracle on Linux/UNIX) and the database is installed loc
