Break them up into several lists:

where
(
obj_name in ('obj1','obj3' etc)
or
obj_name in ('obj1001','obj1003' etc)
)
...

or

Place all the objects in a temp table then do:
where obj_name in (select tmp_object_name from tmp_object_table) ...

There are a couple of other ways but those are probably the most straight forward.

>> I also what to delete tham am in 11gr2

Change the outer most select to a delete?

put them into a collection object
collections have no limit on members

select * from cal_obj
where obj_name in (select * from table(your_collection));

simple example...

create or replace type vcarray as table of varchar2(20);

select * from cal_obj
where obj_name in (select * from table(vcarray('obj1','obj3')));

your function doesn't ever return the collection.

try one of these, one pipelined, one not

CREATE OR REPLACE FUNCTION f_varchar2_table(
ccode_list    IN VARCHAR2,
p_delimiter   IN VARCHAR2 DEFAULT ','
)
RETURN varchar2table
PIPELINED
IS
v_string LONG := ccode_list || p_delimiter;
v_pos    PLS_INTEGER;
BEGIN
LOOP
v_pos := INSTR(v_string, p_delimiter);
EXIT WHEN (NVL(v_pos, 0) = 0);

PIPE ROW (TRIM(SUBSTR(v_string, 1, v_pos - 1)));
v_string := SUBSTR(v_string, v_pos + 1);
END LOOP;

RETURN;
END f_varchar2_table;
/

CREATE OR REPLACE FUNCTION f_varchar2_table(
ccode_list    IN VARCHAR2,
p_delimiter   IN VARCHAR2 DEFAULT ','
)
RETURN varchar2table
IS
v_string LONG := ccode_list || p_delimiter;
v_pos    PLS_INTEGER;
v_data   varchar2table := varchar2table();
BEGIN
LOOP
v_pos := INSTR(v_string, p_delimiter);
EXIT WHEN (NVL(v_pos, 0) = 0);
v_data.EXTEND;
v_data(v_data.COUNT) := TRIM(SUBSTR(v_string, 1, v_pos - 1));
v_string := SUBSTR(v_string, v_pos + 1);
END LOOP;

RETURN v_data;
END f_varchar2_table;
