Reason:
When the 11g DB was started LD_LIBRARY_PATH and LIBPATH were pointing to 10g Home (any DB at the time of startup if the above Library variables are not pointing to current DB ORCLE_HOME)

- in my case we have oracle versions in the server 11g and 10g, at the time 11g DB startup LIB variables are pointing to 10g.

Fix:
I’ve set the below parameters explicitly and restart the database which has fixed the issue
ushux37$ export LIBPATH=/u01/app/oracle/product/11.2.0/lib:/u01/app/oracle/product/11.2.0/lib32
ushux37$ export LD_LIBRARY_PATH=/u01/app/oracle/product/11.2.0/lib:/u01/app/oracle/product/11.2.0/network/lib
