Maintenance
Materialized Views
The materialized views which are part of the APM datamart schema are configured to be refreshed periodically. Normally, this requires no user interaction; however it is possible for the process to get interrupted. To investigate this situation, the following query can be used:
select JOB, LAST_DATE, FAILURES, BROKEN, WHAT from ALL_JOBS WHERE WHAT LIKE '%dbms_refresh.refresh%'The result of this query will contain a row for each materialized view refresh job, with a count of failed executions.
