Home -> Community -> Mailing Lists -> Oracle-L -> Re: V$OBJECT_USAGE view for indexes in all schemas
Which version? In 9.2.0.5 I can access object_usage from another DBA user.
Here is how it works:
SQL> connect mgogala
Enter password:
Connected.
SQL> select * from sys.object_usage;
no rows selected
SQL>
SQL> desc sys.object_usage
Name Null? Type ----------------------------------------- -------- ---------------------------- OBJ# NOT NULL NUMBER FLAGS NOT NULL NUMBER START_MONITORING VARCHAR2(19) END_MONITORING VARCHAR2(19)
SQL> All you need, besides love, is the way to interpret the "flag" column. This might be helpfull:
SQL> select view_name,text from dba_views 2 where view_name='V$OBJECT_USAGE';
VIEW_NAME
decode(bitand(i.flags, 65536), 0, 'NO', 'YES'),
In other words, I believe that your problem is in the version. As Rajendra and Wolfgang have proven, you should upgrade to the version which doesn't know how to merge the query and a subquery. May the force be with you.
