Information in this document applies to any platform.
This article applies to Enterprise Manager (EM) 184.108.40.206 to 220.127.116.11 Cloud Control. Starting with version 18.104.22.168, the server generated alert system is not relied upon as a basis for alerting (for any metric for which it is possible to set a threshold for).
Whenever a target database is in metric collection error or down (wrong password, unconfigured, stopped, etc) status, changing the metric collection settings are updated in the repository but are not being propagated to dba_thresholds of the target due to its state. This is creating a discrepancy between the threshold values in the repository for that target and what is stored in the target's dba_thresholds. Also, in cases where there are errors when saving to the DB server side (dba_thresholds), these are not being returned to the user.
