    TNS-12555 / TNS-12560 / TNS-00525 Error listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1)))

    Problem:

    LSNRCTL for Linux: Version 10.2.0.1.0 – Production on 21-SEP-2011 12:54:12

    Copyright (c) 1991, 2005, Oracle. All rights reserved.

    Welcome to LSNRCTL, type “help” for information.

    LSNRCTL> start
    Starting /u01/app/oracle/oracle/product/10.2.0/db_1//bin/tnslsnr: please wait…

    TNSLSNR for Linux: Version 10.2.0.2.0 – Production
    System parameter file is /u01/app/oracle/oracle/product/10.2.0/db_1/network/admin/listener.ora
    Log messages written to /u01/app/oracle/oracle/product/10.2.0/db_1/network/log/listener.log
    Error listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1)))
    TNS-12555: TNS:permission denied
    TNS-12560: TNS:protocol adapter error
    TNS-00525: Insufficient privilege for operation
    Linux Error: 1: Operation not permitted

    Listener failed to start. See the error message(s) above…

    LSNRCTL>

     

    Cause:

    1) Ensure that /tmp/.oracle or /var/tmp/.oracle directory exists.

    2) Confirm that the DBA user who is trying to start the listener has adequate read and write permissions on the directory specified above. The permissions should be 777.

    3) If the /tmp directory has reached full capacity, this would cause the listener to fail to write the socket files.

     

     

    Solution

    To implement the solution, please use the following example:

    1. cd /var/tmp

    2. Check the whether the .oracle directory exists:

    cd .oracle

    3. If the directory does not exist, request the System Administrator create the directory and set the ownership as root:root with the permissions set to 01777

    mkdir /var/tmp/.oracle 
    chmod 01777 /var/tmp/.oracle 
    chown root /var/tmp/.oracle 
    chgrp root /var/tmp/.oracle

    4. Next try starting the TNS Listener using the ‘lsnrctl start <listener_name>’ command
