Invalid Objects permanent solution required

Question

Hi,
This Oracle invalid objects problem is very consistent in our production database (10g).
select owner,object_name,object_type,status from dba_objects
where status != 'VALID';
OWNER          OBJECT_NAME               OBJECT_TYPE         STATUS
SHOP_LIVE     IEPRODUCTCATEGORYASSIGNMENT1     MATERIALIZED VIEW   INVALID
SHOP_LIVE     IEPCA_NEWSTATE               MATERIALIZED VIEW   INVALID
SHOP_LIVE     IEPRODUCTCATEGORYASSIGNMENT2     MATERIALIZED VIEW   INVALID
SHOP_EDIT     UNSPSCCOUNT1               MATERIALIZED VIEW   INVALID
SHOP_EDIT     UNSPSCCOUNT2               MATERIALIZED VIEW   INVALID
SHOP_EDIT     IEPRODUCTCATEGORYASSIGNMENT1     MATERIALIZED VIEW   INVALID
SHOP_EDIT     IEPCA_NEWSTATE               MATERIALIZED VIEW   INVALID
SHOP_EDIT     IEPRODUCTCATEGORYASSIGNMENT2     MATERIALIZED VIEW   INVALIDAfter I compile manually each materialized view, and then query again and there are NO ROWS SELECTED.
But After some time I get the same problem in other schema, and the same scheme with some other invalid objects. What are the reasons for this kind of error, and Can I get rid of this problem permanently?? If yes then please write steps.....
THanks alot.
Regards,

Hi,
Thank you. Yes I also have noticed that invalid objects are always from these two schemas.
I don't know the meaning of REWRITE_ENABLED,REWRITE_CAPABILITY,REFRESH_MODE,REFRESH_METHOD,FAST_REFRESHABLE from dba_mviews, but options looked not usual after your suggestion. Can you please have a look and suggest something useful from the below columns to change. I mean which change could prevent invalid objects by changing from below columns if works.
SYS@rac1p1 AS SYSDBA> select owner,MVIEW_NAME,REWRITE_ENABLED,REWRITE_CAPABILITY,REFRESH_MODE,REFRESH_METHOD,FAST_REFRESHABLE from dba_mviews
