Issue/Introduction

 

When running a Web Agent on Oracle HTTP Server 12 (OHS), some seconds
after it started, OHS reports an error and cannot starts completly,
even if the Web Agent starts fine :

  [Thu Nov 09 14:07:20.475211 2017] [mpm_event:notice] [pid 18349:tid 1400794=88005952]
  AH00491: caught SIGTERM, shutting down 

and it ask the Web Agent to shutdown : 

  [09/Nov/2017:14:07:20] [Info] [CA WebAgent LLAWP] [18620]
  [Shutdown message=sent to the LLAWP. It should stop within 5 seconds ...] 

Environment

 

Web Agent 12.52 SP1 CR05 64bit on OHS 12c on RedHat 6 64bit;

 

Cause

 

Out of the box, the OHS Node Manager will try to access the /dms/
resource to monitor its availability. If this resource cannot be
reached or have delays in the answer, it might request the OHS Server
to shutdown. If you protect this resource, then the monitor will ask
the OHS to shutdown.

 

Resolution

 

Open the AdminUI, and edit the Domain protecting the Web Agent running
on OHS. In the Policies configuration, unprotect the /dms/ resource on
your Oracle HTTP Server to solve the issue.
