OEM Cloud Control 12c registering stand-alone Oracle HTTP Server 10g

Oracle Enterprise Manager Agents unable to find all the information about the host software where are they were installed. It is still true even if we talk about Oracle Software. Practically we unable automatically take under control standalone Oracle HTTP Server (version 10.1.3.1/ Apache 2.0).
These servers are required for intermediate FMCNA Portal configuration, when applications would be already upgraded (Weblogic 11g/WebCache 11g) and Security Services aren’t (Oracle SSO 10g).
To register Oracle HTTP Server 10.1.3.X on Oracle Enterprise Manager Cloud Control 12c we should complete the follow tasks:

  1. Discover target host
  2. Deploy OEM CC Agent
  3. Add Oracle HTTP Server using Manual Configuration.
First two topics are standard procedures and covered by Oracle Enterprise Manager Documentation.
To register new Oracle HTTP Server 10.1.3.x complete the follow steps:
  1. From the Global Navigation Area select Setup -> Add  Target -> Add Targets Manually
  2. Select  option “Add Non-Host Targets by Specifying Target Monitoring Properties” as on picture below.
  3. Select Target Type from the drop down list
  4. Lookup and select Monitoring Agent for corresponding component host using  button
  5. Press “Add Manually …” button
  6. On the next screen you will see a huge form with a lot of required fields.
  7. In our case not all of them are really necessary, so you could use any reasonable value to fill it out. I’ve used NA, Oracle Support recommends to use put ‘X’ char into it. The really matter fields are there:
    Field nameValueComment
    Target NameDisplay name for targetAny name except special characters
    EM Target Typeoracle_apacheOracle Support recommended value
    Machine namefull.server.name.comFully qualified host name
    Port Number7777Default Listen port for HTTP
    Version of Apache2.0Actual Apache server version for Standalone Oracle HTTP server 10.1.3.1 – 2.0
    Oracle Home Path/oraclewls/admin/ohsFull path to Oracle HTTP Server home dir
    OPMN Port Number7777Listen HTTP Port
    Version CategoryStdApacheOracle Support recommended value

    1. Fill all required fields with fake values of your choice.
    2. Fill out Global properties to describe target Location, Lifecycle and etc.
    3. Save the target parameters.
    4. If all was done right you will able to see target home as follow.

Therefore, you can only see the status of OHS . No performance related metrics, no control, no configuration changes. Thanks to Cloud Control developers there are great metric extensions functionality.
