OEM automatic discovery discovers not

Hello, DBAers; RHEL 5 x 64, Oracle Enterprise Manager 12.1.0.3 - trying to discover a host unmanaged using auto-discovery and following the instructions outlined here

http://docs.Oracle.com/CD/E24628_01/doc.121/e24473/discovery.htm#EMADM13119

and auto-discovery is not discovered.

I can "ssh < usrname > @ < host name >"to connect to the target unmanaged machine running the administration server and ping the target of the same server, so it doesn't seem to be a firewall problem. "  But OEM is unable to see through the automatic detection.  Any of you have ideas?

Humbly,

Solved.  Port 443 didn't open on the unmanaged target.

Thank you for your time!

  • I need help, its frustrating me! network discovery does not illuminate.

    my network discovery does not illuminate. Whenever I try to turn it on I get an error message that says: (the specified service does not exsist as an installed service)! I need to elp, its frustrating me! I have windows vista.

    Hello

    Did you change your computer?

    Method 1:

    Based on the network location you choose, Windows affects a State of network for network discovery and opens the Windows Firewall ports suitable for this State.

    Step 1: We recommend you to check if the elements of network discovery are enabled in Windows Firewall. To do this, try the following steps.
    1. click on start, type firewall and then click Windows Firewall with advanced security.
    2. click on rules of incoming traffic in the left pane and select the (SSDP-In) network discovery and network discovery (UPnP) - in the list.
    3. click on rules of outgoing traffic in the left pane and enable network discovery (SSDP-out) and the discovery of the network (UPnP-Out) in the list.
    4. apply the changes and check the result.

    For more information about network discovery, see this link:
    http://Windows.Microsoft.com/en-us/Windows-Vista/what-is-network-discovery

    Step 2: Check the status of the following services: browser, TCP/IP NetBios support.
    1. Click Start, type services.msc and press to enter.
    2. from the list of services, double-click the service computer browser and TCP/IP NetBios support.
    3. change the startup type to automatic and start the service.
    4. apply the changes.

    Method 2:

    Now we go ahead and try to enable the discovery of the network on your computer and check for the issue.

    Network discovery is disabled by default for public networks. Changing a network location type to home or work is the best way to turn on network discovery. To learn how to change a network location type, see Choosing a network location. To enable discovery manually, follow the steps below.

    To turn on network discovery

    1. open the network and sharing Center by clicking the Start button, clicking Control Panel, clicking Network and Internet, and then click Network and sharing Center.

    2. If network discovery is off, click the arrow button expand the section, click turn on network discovery, and then click on apply. Need administrator permission if you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

    I also suggest you turn on discovery of the network link and check.

    Enable or disable network discovery

    Hello, BahaaJ

    It may not seem obvious--after all, this thread of 2010 is, apparently, more precisely on the problem that you are facing, and you've probably found this thread via a search for one or the other parameters of the problem (perhaps a search for "Network discovery" or something similar?)- but I think you will find that it is almost always a better idea to create your own community for any particular issue thread You can have. That's because the new questions will always come to the attention of the Forum (Microsoft employee) or community (volunteer expert) while discussion moderators, posts and assignments to old threads (such as 2010) do not necessarily automatically come to the notice of moderators - or the 'Community' Stars that often offer some of the best answers to questions from the Member of the community; many of the former use community tools to look for questions specifically so that they can provide assistance.

    I also believe that how a question is asked can affect the response that we receive; to this end, I find that

    the Wiki article created by the author of Wiki, moderator of the community and MVP ZigZag3143 (MS-MVP), "effective questions get help faster!", and article KB555375 in the Microsoft Knowledge Base "Suggestions for a question on help forums" are both useful.»»  A prolem as you report, I would say

    from your own new thread @ page of the answers community to ask a Question-Windows category (be sure to select the right operating system for your computer in the drop-down "Version of Windows", while I would suggest selecting "Web and networks" in the drop down list 'Headings Windows').

    That being said, if you have found that perform the troubleshooting steps described by

    H Shinmila in his post on March 3, 2010 on this subject did not help, you might want to take a look @ Edgardo Ton February 22, 2011 post Microsoft Support Engineer in the similar thread "Network Discovery will not or enabled.'." "  There is also Microsoft official troubleshooting articles related to his position (mainly written for Vista, but largely as well) applicable to new versions of Windows.  It is also worth noting that what Greg Blevins published on page 1 in this thread we are currently (January 15, 2014 - the post before yours) on its damaged with Windows Firewall policies is very common source of problems such as you are facing. If you do not have the option which he used to import working strategies exported from the machine to another, of work, you might want to try repair Windows Firewall of Tweaking.comtool (part of their Windows repair software (all-in-One)); all has been updated to 2.7.1 v. but apparently the firewall tool is only still v. 2.7.0 this writing.  The tool can be downloaded from this page: repair Windows Firewall 2.7.0.

    Good luck!

  • Download Microsoft Office Home & Student 2007 but the automatic updates do not work.

    Hello. Thanks in advance for your help here.

    I am at a loss to know what to do.

    Recently, I downloaded Microsoft Office Home & Student 2007, which seems to be very well. The problem is the automatic updates do not work. After searching online, I did the start > run > Winver and he says I have Service Pack 3. Then I went to control panel in Add/Remove Programs, and even if it is listed, there is no indication that it is actually installed.

    I remember a year or there are problems with SP3, when I tried to upgrade to IE8 so "I THINK" I removed it. Probably shouldn't have done that!  But IE8 has worked fine once I removed it. Microsoft says that we will no longer receive automatic updates to SP2 in June and so we have to upgrade to SP3.  Well, I just don't know what I have on my computer at this point!

    Anyway, now I get these failed messages on the updates for the Office:

    The 2007 Microsoft Office Suite Service Pack 2 (SP2)
    Update for Microsoft Office System 2007 (KB967642)
    Update of security for Microsoft Office System 2007 (KB951944)
    Update of security for Microsoft Office 2007 (KB951550)

    So I thought I'd download the SP2.  But I did not know if Microsoft .NET Framework 2.0 Service Pack 2 actually means I have SP2 installed or not.  And I got in such a mess last year I don't want to take any chances again.

    I'm sorry that it is a message that is too long. I tried to print screens to attach more information, but that did not work. Let me know what you need.

    Thank you very much in advance for your help.

    Diane

    I found more information. Looking in my history of update for automatic updates, all 4 of these updates failed have the same error Code which is: 0 x 80070663.  I don't know if this info helps solve this problem or not, but that's it.

    Hello
     

    a. you are able to download and install updates in Windows other than Microsoft Office?

    If you have SP3 listed in the Windows Version (winver) which ensures that you have Windows XP SP3 installed.
     
    Let us download the updates manually and install them, here are the links to download.
