    try to unset the env. variable ORACLE_PATH on client machine and post the tsnnames.ora from the client m/c.

    and try setting the ORACLE_HOME and ORACLE_SID from the client and give a try...

    dear madhu,

    I have unset the oracle_path in the client and set the oracle_sid and oracle_home.

    but still it is giving the same error.

    Error: ORA 7429
    Text: smsgsg: shmget() failed to get segment.
    Cause: a shared memory segment used for all part of the SGA could not be
    Action: Use the system error number in the error message to determine why
    the segment could not be retrieved. If it does not exists, shutdown
    the database using the "abort" option, and then restart it.
    If the get failed because the permissions are incorrect, make sure
    that the ownership of the oracle executable is the same as that on
    the shared memory segment.

    *** Important: The notes below are for experienced users - See [NOTE:22080.1]

    This is typically reported when a user tries to connect to a
    database but either the database is NOT running or the user has
    their environment set up incorrectly.

    - Is the database actually running ?

    - Is the connection attempt local or to a remote database ?

    - Check ORACLE_HOME and ORACLE_SID are correct:

    env | grep ORACLE

    The ORACLE_SID is case sensitive and MUST match the instance

    - Check ORACLE_HOME and the ORACLE_SID thus:

    cd $ORACLE_HOME/dbs
    ls -l sgadef$ORACLE_SID.*

    If the 'cd' fails ORACLE_HOME is incorrect. If the 'ls' shows
    no files then either the database is not running OR
    ORACLE_SID is wrong.

    - Check the Operating System error number after the ORA 7429

    Error 2 Is typically wrong ORACLE_SID or ORACLE_HOME
    Error 13 Is typically incorrect permissions on the
    'oracle' executable. As the Oracle user ensure
    the permissions are correct thus:

    cd $ORACLE_HOME/bin
    chmod 4755 oracle

    If the database is started as 'root' and the
    permissions are wrong you need to:
    Shutdown the database as root
    Change the permissions as above
    Restart the database

    - For SQL*Net V1 over TCP/IP ensure that the ORACLE_HOME in
    the oratab file (/etc/oratab or /var/opt/oracle/oratab)
    is EXACTLY correct for the instance.

    - For SQL*Net V2 over TCP/IP ensure that the ORACLE_HOME in
    the listener.ora file is EXACTLY correct for the instance.
    This file should be in one of:
    or $ORACLE_HOME/network/admin/listener.ora
