How to compile packge inside procedure which uses this package

Question

ORACLE 10g, 11g
CREATE OR REPLACE PACKAGE PKG_TEST_COMMIT
PROCEDURE Insert_into_table_T1;
PROCEDURE Update_table_T1;
END PKG_TEST_COMMIT;
CREATE OR REPLACE PROCEDURE PROC_TEST_COMMIT As
Begin
PKG_TEST_COMMIT. Insert_into_table_T1; --insert data into table T1
EXECUTE IMMEDIATE 'DROP table T1';
EXECUTE IMMEDIATE
'create table T1 as select ''1'', ''d'', ''s' from DUAL'; -- now package PKG_TEST_COMMIT in uncompiled stage
-- compile package
DBMS_DDL.alter_compile('PACKAGE', 'OWNER', 'PKG_TEST_COMMIT');
PKG_TEST_COMMIT. Update_into_table_T1;
End PROC_TEST_COMMIT;
When I try to run PKG_TEST_COMMIT I’Ve got an error: can’t lock the package.
I tried to create separate procedure for compilation, but result is the same.
If I finish PROC_TEST_COMMIT before compiling, then compile – OK.
Is there is a way to compile package inside the procedure?

Answer 1

I need to automate the process which first call some procedure from the package, then invalidate this package by dropping and recreating the table (I didn't create the code, but I can see thepoint init - this is the farstest way to populate huge table) and then call another proc from the same package (using table just cretated).
Otherwise I need human attention to this process. If it is imposible I can substitude "drop table and create table" for truncate and insert", but I am afraid it will take too long.
