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
retrieved.
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]


Explanation:
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.

Diagnosis:
- Is the database actually running ?

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

Local:
- Check ORACLE_HOME and ORACLE_SID are correct:

env | grep ORACLE

The ORACLE_SID is case sensitive and MUST match the instance
ORACLE_SID.

- 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
message.

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

TCP/IP:
- 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:
/etc/listener.ora
$TNS_ADMIN/listener.ora
/var/opt/oracle/listener.ora
or $ORACLE_HOME/network/admin/listener.ora
