lib/libclntsh.a(shr.o) could not be loaded

User other than oracle was trying to access the libraries and getting the below errors:

$exec(): 0509-036 Cannot load program FastReader because of the following errors:
0509-150 Dependent module $ORACLE_HOME/lib/libclntsh.a(shr.o) could not be loaded.
0509-022 Cannot load module $ORACLE_HOME/lib/libclntsh.a(shr.o).
0509-026 System error: The file access permissions do not allow the specified action.

Fix:
in 10g Oracle introduced strong security in accessing the oracle binaries, so to flex this security run the below command:

cd $ORACLE_HOME/install
>./changePerm.sh
