All about During daily maintenance!!!
During daily maintenance in Oracle EPM
Cloud, the system creates a maintenance snapshot, applies patches, adjusts
configurations, and analyzes activities to generate an Activity Report. The
environment is then rebooted, with initial access limited to Service
Administrators. Certain operations are restricted during this period,
especially for processes like Planning and Financial Consolidation. Maintenance
usually starts between 10:00 p.m. and 1:00 a.m. local time and a 15-minute
notice is given before maintenance begins. The process typically takes less
than an hour.
