I'm just not able to get past this error. I can connect just fine locally on my server (CentOS), but continue to get the TNS:no listener error when trying to connect via my Mac (OSX Mavericks) which is on the same subnet. Below are some notes I've captured based on what information I see that has been requested for this type of issue: -------------------------------------------------------------------------------- MISC NETWORK CONFIG: -------------------------------------------------------------------------------- [root@rubyrailssvr ~]# more /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.1.14 rubyrailssvr.homenet.com [root@rubyrailssvr ~]# [root@rubyrailssvr ~]# more /etc/sysconfig/network NETWORKING=yes HOSTNAME=rubyrailssvr.homenet.com [root@rubyrailssvr ~]# -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- LISTENER.ORA File: -------------------------------------------------------------------------------- [oracle@rubyrailssvr ~]$ more /u01/app/oracle/product/11.2.0/xe/network/admin/listener.ora # listener.ora Network Configuration File: SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = PLSExtProc) (ORACLE_HOME = /u01/app/oracle/product/11.2.0/xe) (PROGRAM = extproc) ) ) LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE)) (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.14)(PORT = 1521)) ) ) DEFAULT_SERVICE_LISTENER = (XE) [oracle@rubyrailssvr ~]$ ----------------------------------------------
incorrectly. Action: Turn on tracing at the ADMIN level and reexecute the operation. Verify that the ORACLE Server executable is present and has execute permissions enabled. Ensure that the ORACLE environment is specified correctly in LISTENER.ORA. The Oracle Protocol Adapter that is being called may not be installed on the local hard drive. Please check that the correct Protocol Adapter are successfully linked. If error persists, contact Oracle Customer Support. ORA-12502: TNS:listener received no CONNECT_DATA from client Cause: No CONNECT_DATA was passed to the listener. Action: Check that the service name resolved from TNSNAMES.ORA has the CONNECT_DATA component of the connect descriptor. ORA-12504: TNS:listener was not given the SID in CONNECT_DATA Cause: The SID was missing from the CONNECT_DATA. Action: Check that the connect descriptor corresponding to the service name in TNSNAMES.ORA has an SID component in the CONNECT_DATA. ORA-12505: TNS:listener does not currently know of SID given in connect descriptor Cause: The listener received a request to establish a connection to a database or other service. The connect descriptor received by the listener specified a SID for an instance (usually a database instance) that either has not yet dynamically registered with the listener or has not been statically configured for the listener. This may be a temporary condition such as after the listener has started, but before the database instance has registered with the listener. Action: - Wait a moment and try to connect a second time. - Check which instances are currently known by the listener by executing: lsnrctl services
