I am working on Oracle Forms9i. After every compilation and execution of the form it locks the referred procedure/view inside for some period. During this period it does not allow to modify the procedure/view. While trying so it gives following error message after 3-4 minutes of issuing the create or replace command.

*** Error message *****
ORA-04021: timeout occurred while waiting to lock object SECURITY.USER_MENU1

Can you suggest how to get rid of this problem.

Thanks,

seems like an LC lock.
query the v$access to see which user is causing the lock.
Make sure ur code is not affecting the objects / blocks u are currently accessing and being dependent on

dbadmin@mutation_mutation > desc v$access
 Name                                                  Null?    Type
 ----------------------------------------------------- -------- ------------------------------------
 SID                                                            NUMBER
 OWNER                                                          VARCHAR2(64)
 OBJECT                                                         VARCHAR2(1000)
 TYPE                                                           VARCHAR2(24)
