expdp utility corruption

sometimes, the expdp utility may be corrupted, in this case either the expdp file which is inside the $ORACLE_HOME/bin folder may be missing or the filesize is 0 bytes,

Easiest method to solve this issue is to copy the expdp from a working server to the server which is not working - make sure that we need to copy from the same version of the database example if the server which is having trouble is running in the Database ver 10.2.03 then, the file which is copied should also run in the version 10.2.03.

After this it will show the error message as /opt/oracle/product/10gR2/bin/expdp: error while loading shared libraries: libclntsh.so.10.1: cannot open shared object file: No such file or directory when trying to run the expdp file.

Soltion for this is we need to set the environment variable as follows.

$export LD_LIBRARY_PATH=$ORACLE_HOME/lib
Make sure that you have set the ORACLE_HOME variable before.
