DBIDs and forcing updates to DBA_FEATURE_USAGE_STATISTICS in 12c CDBs

edited Jun 19, 2017 11:42AM in Database Tuning (MOSC) 5 commentsAnswered

Has anyone got any new tips or undocumented suggestions for forcing updates to the wri$_dbu_feature_usage / wri$_dbu_usage_sample data with 12c container databases?

What I'm finding is that if I create a new 12c CDB using a template, I'm having a hard time forcing the template's DBID data out and getting the PDBs to collect new FUS data without having to wait a week for MMON (I believe that's still the background process responsible but I could be mistaken).  Procedures such as "dbms_feature_usage_internal.exec_db_usage_sampling" don't seem to work as (by sql tracing them) I see that they're not matching on the DBIDs in the underlying wri$ tables.

Howdy, Stranger!
