Title: RE: Invalid packages not being recompiled by Oracle

Paul,

 

Lisa has the correct answer - you must recompile all dependent items. 

This behavior has been standard since the beginning of PL/SQL.

 

Actually, if your application could be changed to capture the error, and just call the package a second time, all would be well - that is - the package would be compiled by the call, and be validated.

 

I would suggest either running the dbms_utility.compile_Schema utility (which I am not a fan of, as it sometimes dies with a recursive sql error) or running the script below which will re-compile all invalid objects within the schema.

 

hope this helps.

 

 

set heading off
set pagesize 5000
set pages 100
set serveroutput on
exec dbms_output.enable(500000);
spool compile.sql
declare
cursor c1 is
  select 'alter ' || object_type || ' ' || object_name || ' compile;' out_line
  from user_objects
  where status='INVALID'
  and object_type in ('PROCEDURE','PACKAGE','FUNCTION','VIEW','TRIGGER')
  order by 1;
begin
 for c1_rec in c1 loop
   dbms_output.put_line(c1_rec.out_line);
 end loop;
 dbms_output.put_line('exit');
end;
/
spool off
@compile

HI Paul,

By chance can you use dbms_utility.compile_Schema after recompiling? Are you using it already?  I know it doesn't answer your quesiton but this package is suppossed to follow the dependencies, no matter how odd they are (what you are describing below is pretty weird).

We have one package A that refers to package B. If package B's body and
specification are both recompiled by user 1, package A is correctly marked
as invalid. Another user, user 2, then attempts to execute package A and
gets the following error stack:

-- ORA-04068: existing state of packages has been discarded
-- ORA-04061: existing state of package "B" has been invalidated
-- ORA-04065: not executed, altered or dropped package "B"
-- ORA-06508: PL/SQL: could not find program unit being called
-- ORA-06512: at "B", line n ORA-06512: at line 2

User 2 then issues the statement 'alter package A compile;' It compiles
successfully and user 2 can now execute the package.

Why does Oracle not automatically recompile package A as it should? Since
user 2 was able to recompile the package in its existing state, Oracle
should not have failed at doing so. User 2's session instantiation of
package A (as well as all of their other instantiated packages) should have
been lost when package A was invalidated.

I understand that two possible options are: (1) Flush the shared pool after
recompiling; and (2) Manually recompile all dependent packages (such as A).
The first seems like overkill and will cause performance issues. The second,
with many dependencies involved, is not an option.

We need to consistently be able to recompile a package that other packages
are dependent upon without a user recieving the above error stack in
addition to not impacting performance or without having to recompile all the
dependent packages.

Thanks in advance,

- Paul
