SQL & PL/SQL

Hi All

When I tried to compile a package I got the below error.

create or replace package my_sample_pack
*
ERROR at line 1:
ORA-04021: timeout occurred while waiting to lock object my_sample_pack

Then I queried

 v$access 

. There is an entry. I also, flushed the shared_pool. But still this problem exists. What should I do from here?

Thanks in advance.
