Kevin:

Thank you.

Restarting the listener process by unsetting LD_ASSUME_KERNEL env. variable did the trick!

$ ps -ef|grep tns
oracle 21772 1 0 19:18 ? 00:00:00 /ispiris-test/orasrc/product/db/10.2.0.2/bin/tnslsnr LISTENER -inherit

We set this variable " LD_ASSUME_KERNEL=2.4.19" for Oracle account as recommended for binary installation

Would you see any pros/cons by setting/ignoring this value.

Following is a ref. from *Werner Puschitz's* note on this variable for Oracle installation

# *Set the LD_ASSUME_KERNEL environment variable only for Red Hat 9, *
# *RHEL AS 3, and RHEL AS 4 !!*
# Use the "Linuxthreads with floating stacks" implementation instead of

NPTL:
export LD_ASSUME_KERNEL=2.4.1 # for RH 9 and RHEL AS 3 export LD_ASSUME_KERNEL=2.4.19 # for RHEL AS 4
