The Oracle database which hosts our UC4 database schema get's patch every quarter.
For production, we always bring down the Engine during this patching.
For our test environment, we never have brought down our engine during Db Patching and there have been no repercussions.
During patching our DB goes down for between 7-15 minutes.
For the most recent test DB patch, we did notice slowness with all Jobs and subsequently and had to recycle our engine to fix.
Just wondering what others out there do when their DB goes down for a short period of time like this?
Do you always bring down engine?
