What kind of connections exist between the client and the server, for example, X.25, ISDN, or leased line? Check the type of naming adapters listed in the names.directory_path parameter in the sqlnet.ora file. I have tested TNSPING ORCL coming fine Blockquote C:\\Windows\\system32>TNSPING Is your local connection working? Table 16-14 Service Registration Event Log Information. Testing assumes the listener and database are running. Diagnostic parameters are found in the following configuration files: Table 16-4 compares usage of diagnostic parameters found in the sqlnet.ora file used in both ADR and non-ADR-based diagnostics. After updated tnsnames.ora and sqlnet.ora files, I tested connection to local database (in the same PC) from TOAD and SQL Plus, it works fine. @AlexPoole Im connecting to a real IP(192.168.1.6) and in the lsnrctl status command i had these: (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=127.0.0.1)(PORT=1521))) does it mean i need to change the listener in listener.ora? You can configure cman.ora to log events for the following categories: Events associated with connection control blocks. The Trace Assistant works only with level 16 (support) Oracle Net Services trace files. Using oerr, you can find out more information about return codes 12537, 12560, and 507. 2. tnsping for the connect alias works, no issues. My tnsnames.ora: MYSID = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP) (HOST = my_host) (PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = mySID) ) ) I verified that the listener is running and listening at the post 1521: s$ sudo netstat -tulpn|grep 1521 The number of files is specified with the TRACE_FILENO parameter. This information is output to files that can be evaluated to identify the events that led to an error. If the net service name in the connect string is simple, then check the NAMES_DEFAULT_DIRECTORY parameter in the sqlnet.ora file. The trace file names are distinguished from one another by their sequence number. If the TRACING parameter is enabled, then a time stamp in the form of dd-mon-yyyy hh:mi:ss:mil is created for every trace event in the listener trace file. Listener 'blocked', database is down or in nomount state only and there's no static registration in listener.ora. The level of detail the trace facility records for the client.

Remember that an IP address can be forged. If an error occurs, then applications such as SQL*Plus, that depend on network services from Oracle Net Services, normally generate an error message. Other ADRCI command options are available for a more targeted Oracle Net trace file analysis. The CMADMIN and gateway log files are reproduced here. When this parameter is set along with the TRACE_FILELEN parameter, trace files are used in a cyclical fashion. Oracle Connection Manager CMGW (Oracle Connection Manager gateway) process, Oracle Connection Manager CMADMIN (Oracle Connection Manager Administration) process.

I don't suspect the firewall, because like I say, telnet works. 32bit is not bad for developing but I hope I can fix the 64bit problem. The name of the trace file for the client. If one computer works and another does not, and the same software (Oracle and third-party products) is installed on each computer, then, if possible, swap out the network cables to see if the problem occurs on the second client. If no options are provided, then the default is -odt -e0 -s, which provides detailed connectivity and TTC events, error level zero (0), and statistics in the trace file. - I ran applications process monitor and got the following: Following the advice of the document, it might indicate that I have the 32-bit version of lite client installed and am running 64 . * (ADDRESS=(PROTOCOL=tcp)(HOST=85.202.227.93)(PORT=58735)) * establish * SRVORA * 0.

This layer provides a generic interface for Oracle clients, servers, or external processes to access Oracle Net functions. This extends the timeout in the client. Exit the text editor and at the command line, type: Oracle Net Services logs provide detailed information about the source and context of problems. The trace level value can either be a value within the range of 0 (zero) to 16 where 0 is no tracing and 16 represents the maximum amount of tracing, or one of the following values: off (equivalent to 0) provides no tracing. The address in the connection needs to match the listener address; so yes, change the connection to 127.0.0.1. " In the navigator pane, expand Profile under the Local heading. Someone is trying to connect to CMADMIN directly (possibly a denial of service attack). To view trace files using ADRCI, enter ADRCI at a command line. The last is a chronological record of all critical errors. Figure 16-2 illustrates the directory hierarchy of the ADR for an Oracle Connection Manager instance. The connection was disconnected because it exceeded the session timeout specified in cman.ora. To learn more, see our tips on writing great answers. This can occur with cyclic trace files. You can use the Listener Control utility SERVICES command to see what instances are currently registered with the listener. The listener received updated registration information for a particular instance, such as dispatcher or instance load information. That blocker session is itself occupied in a long-running activity (or its own hang) which prevents it from releasing the shared resource needed by the authenticating session in a timely fashion. The process of logging and tracing error information helps you to diagnose and resolve network problems. All registration information for the instance is discarded. However, other errors may also exist within the trace file that were not logged from the nserror function.
