DBA_* tables - is it a dynamic or static?

Question

Hi,
We have RAC database in which we have 10 instances.(Host 1,Host2 ...Host10)
I would like to clarify that if i need to check locks using the below query in all the host.
select from dba_dml_locks where name like '%$obj%';*
select from dba_ddl_locks where name like '%$obj%';*
Please clarify dba_dml_locks and dba_ddl_locks are dynamic view or static table as we are executing in all the instances.

Answer 1

DBA_VIEWS view has column "text" to show the view source.
For instance,
UKJA@ukja102> set long 10000
UKJA@ukja102> select text from dba_views where view_name = 'DBA_DDL_LOCKS';
TEXT
select  s.sid session_id,
          substr(ob.kglnaown,1,30) owner,
          substr(ob.kglnaobj,1,30) name,
    decode(ob.kglhdnsp, 0, 'Cursor', 1, 'Table/Procedure/Type', 2, 'Body',
           3, 'Trigger', 4, 'Index', 5, 'Cluster', 13, 'Java Source',
             14, 'Java Resource', 32, 'Java Data', to_char(ob.kglhdnsp)) type,
    decode(lk.kgllkmod, 0, 'None', 1, 'Null', 2, 'Share', 3, 'Exclusive',
           'Unknown') mode_held,
    decode(lk.kgllkreq,  0, 'None', 1, 'Null', 2, 'Share', 3, 'Exclusive',
           'Unknown') mode_requested
   from v$session s, x$kglob ob, x$kgllk lk
   where lk.kgllkhdl = ob.kglhdadr
   and   lk.kgllkuse = s.saddr
   and   ob.kglhdnsp != 0Well, the view source clearly says that DBA_DDL_LOCKS view is based on other dynamic views and fixed tables.
