Last updated on JUNE 29, 2017

Applies to:

Enterprise Manager Base Platform - Version 12.1.0.2.0 to 12.1.0.5.0 [Release 12.1]
Enterprise Manager for Fusion Middleware - Version 12.1.0.2.0 to 12.1.0.8.0
Information in this document applies to any platform.

Symptoms

The issue occurs with Enterprise Manager (EM) 12.1.0.2 or 12.1.0.3 Cloud Control installation: either with an upgraded environment or with a newly installed system.

The Oracle HTTP Server is actually UP, but  target of the Cloud Control stack is frequently reported Down. 

 To confirm if ohs1 is actually UP, someone can check the ohs processes running from Middleware home and ohs logs files (/gc_inst/WebTierIH1/diagnostics/logs/OHS/ohs1/*)
