Any ideas what might be stopping the connection? Pinning will prevent them from being flushed out due to inactivity and aging and will therefore prevent them for needing to be reloaded in the future i.e. In listener.log there is 1 row when I try to connect: 29--2014 17:56:41 * (CONNECT_DATA=(SID=SRVORA)(CID=(PROGRAM=C:\app\oracle\product\11.2.0\client_1\bin\sqlplus.exe)(HOST=DANIILNOTEBOOK)(USER=??????))) By default, the directory is ORACLE_HOME/network/log, and the file name is listener.log. The listener received updated registration information for a particular instance, such as dispatcher or instance load information. The following example shows the adapters: The net service name given in the connect string should be defined for at least one of the naming methods. Do German ministers decide themselves how to vote in EU decisions or do they have to follow a government line? The database server passed a loopback test, showing that the connection worked. To run the Trace Assistant, enter the following command at any command line prompt: The options are described in Table 16-22. You need to check what address your listener is using too though. This information is output to files that can be evaluated to identify the events that led to an error.

I have installed oracle_11g client in application machine. Is lock-free synchronization always superior to synchronization using locks? If the TNS-12154 error still persists, then determine whether the files were transferred from the client to the server and check the configuration files to ensure that CTRL-M (^M) or CTRL-R (^R) characters were not inserted at the ends of any lines. After successful notification, listeners record the event in the log. A successful registration returns a code of zero, meaning the client can connect to the instance. Trace Assistant also enables you to view data packets from both the Oracle Net and TTC communication layers. CMADMIN cannot process a connection request. Table 16-6 cman.ora File Diagnostic Parameter Comparison, Oracle Call Interface Programmer's Guide for information about the location of the client ADR Home, Oracle Database Administrator's Guide for additional information about ADR, Oracle Database Net Services Reference for descriptions of the following diagnostic parameters.

The number of trace files for database server tracing. If you are using TCP/IP addresses, then use the IP address rather than the host name. If it is a wide area network (WAN), then identify any intermediate systems that may not work correctly. In this output, Receive is the operation. They are the most recent errors and the source of the problem with the connection. This chapter describes common testing procedures and network errors, and outlines procedures for resolving problems. 4. Issue because connection establishment or communication with a client failed to complete within the allotted time interval.

For example, if the default trace file of listener.trc is used, and this parameter is set to 3, then the trace files would be named listener1.trc, listener2.trc and listener3.trc. This may be a result of network or system delays; or this may indicate that a malicious client is trying to cause a Denial of Service attack on the server. For example, change the (HOST=server_name) line in the tnsnames.ora file with the IP address, for example (HOST=192.168.2.5). The first file is filled, then the second file, and so on. To see the IP address of the Oracle service, issue an lsnrctl status command and check the address reported (in this case is 127.0.0.1, the localhost): To see the host IP address, issue the ipconfig (under windows) or ifconfig (under linux) command. ADRCI enables you to: Package incident and problem information into a zip file for transmission to Oracle Support Services. This client could be attempting a denial-of-service attack on the listener. This net service name should match the name in the tnsnames.ora file exactly if the name is simple and there is not NAMES_DEFAULT_DOMAIN in the sqlnet.ora file, or the net service name is a fully-qualified name.

The listener uses asynchronous subscription for the event notification. For example: A message appears, confirming that you are connected with the database. For example, if this parameter is set to 3, then the Oracle Connection Manager trace files for the gateway processes would be named instance-name_cmgw1_pid.trc, instance-name_cmgw2_pid.trc and instance-name_cmgw3_pid.trc. Internal housekeeping for the gateway process is in order. Restart LISTENER with the following commands. Verify that the listener on the remote node has started and is running.
