We just had a major issue with a materialized view (aka snapshot) job running for over two months without end.

 

This actually caused a loss of revenue for our company, as this job generated data which reported customer service usage.

 

I can remember an old 8.1.5 but where an network outage would cause these jobs to hang, but this was supposedly fixed.

 

The only solution I can see is to generate a script which validates that a job in dba_jobs_running is not there over a certain

Period of time.  The issue with this is that that “period of time” may be ill-defined.  The refresh interval stored in dba_mviews is a relative date/time calculation, and does not lend it self to comparative testing.

 

I can provide more detail on this dilemma if anyone needs them. 

 

Any ideas?
