Oracle 11G/ MV log is newer than the last full refresh

Question

MV log is newer than the last full refresh / MV-Log ist neuer als letzter vollständiger Refresh
Oracle 11G
We access from two data banks about MATERIALIZED VIEWs a big master table.
The second data bank is new created. A Complete-Refresh lasts > one hour.
Then never takes place fast-refresh because the MV log on the master db
does not reproach with the data long enough. What can we do? Can one
increase the hold duration of the data in the MV LOG?
Thanks!

Answer 1

What do you get with the following query on the side of your master table?
with
sg as
(select segment_name,owner, bytes
   from sys.dba_segments
  where segment_name like 'MLOG$%'),
tb as
(select owner, object_name, object_type, created, last_ddl_time
   from sys.dba_objects where object_type = 'TABLE')
select
  bm.owner bm_owner,
  ml.log_owner ml_owner,
  bm.master bm_table,
  ml.master ml_table,
  ml.log_table log_table,
  sg.bytes log_size,
  tb.created log_created,
  tb.last_ddl_time log_modified,
  bm.mview_id bm_id,
  rm.mview_id rm_id,
  rm.owner s_owner,
  rm.name s_table,
  rm.mview_site s_site,
  rm.can_use_log,
  rm.version,
  ml.rowids ml_rwid,
  ml.primary_key ml_pk,
  rm.refresh_method rm_meth,
  ml.sequence ml_seq,
  ml.include_new_values ml_new,
  bm.mview_last_refresh_time
from            sys.dba_registered_mviews rm
full outer join sys.dba_base_table_mviews bm
  on bm.mview_id = rm.mview_id
full outer join sys.dba_mview_logs ml
  on bm.master = ml.master and bm.owner = ml.log_owner
full outer join sg
  on ml.log_table = sg.segment_name and ml.log_owner = sg.owner
left outer join tb
  on tb.owner = sg.owner and tb.object_name = sg.segment_name
where
     bm.master is null
  or bm.master = :mastertable
  or ml.master is null
  or ml.master = :mastertable
order by 1,2;For :mastertable you have to insert the name of the table, where you created the MV LOG on.
