EM 12c: Server Generated Alerts Settings in Enterprise Manager 12c Cloud Control are not Saved if the Target is in Metric Collection Error or Down Status (Doc ID 1631364.1)

Last updated on JANUARY 18, 2023

Applies to:

Enterprise Manager for Oracle Database - Version to [Release 12.1]
Information in this document applies to any platform.
This article applies to Enterprise Manager (EM) to Cloud Control. Starting with version, 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).
See "Changes to Oracle Database Monitoring in Enterprise Manager Cloud Control" for more information on this.


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.  

Please note, this problem affects Enterprise Manager Cloud Control and lower.  This problem does not affect Cloud Control and later versions.  In onwards, all metrics for which it is possible to set a threshold for, will be evaluated by the agent and will not rely on the server generated alert system. See <Note:1680788.1> "Changes to Oracle Database Monitoring in Enterprise Manager Cloud Control"   for more information on this.
