                    Please respond

                    to ORACLE-L

 

 

I'm confused, has anyone ever seen something like this before?

This query works as you can see:

select count(*)
from markview.mv_user_enabled_doc_type_privs_at_mv_apps2sup_mi.world;

  COUNT(*)

    275375

We execute the following DDL:

DROP SYNONYM MV_USER_ENABLED_DOC_TYPE_PRIVS; CREATE SYNONYM MV_USER_ENABLED_DOC_TYPE_PRIVS    FOR MARKVIEW.MV_USER_ENABLED_DOC_TYPE_PRIVS_at_MV_APPS2SUP_MI.WORLD; We run the following query:
select count(*)
from mv_user_enabled_doc_type_privs;

The query hangs for over an hour before being killed. When traced it shows it is waiting for the other side to respond.

On the other hand, if I do this you can see it works!

  1* select count(*) from user_tables_at_mv_apps2sup_mi.world SQL> /   COUNT(*)

         0

SQL> create synonym mine for user_tables_at_mv_apps2sup_mi.world;

Synonym created.

SQL> select count(*) from mine;

  COUNT(*)

         0

The hanging behavior is true for every table in the markview schema.
