User_7ACVM

in Enterprise Manager

Hello,

could you help me please ? I looking for since few weeks.

I have installed a new agent oracle 11g (Windows 2016 server) with EM1 2C OMS server is W2K12 R2.

The both servers are the same location (same VLAN) and windows firewall : port 1159 and 3872 are allowed on the both servers (ingoing / outgoing trafic)

In OMS console, I see the new host and new agent : "unable to connect to http server at https://agent:3872/emd/main/. [peer not authenticated].

From agent :

    Hi,

    If targets.xml is empty run from the agent home\bin:

    emctl config agent addinternaltargets

    and

    emctl upload agent

    may solve your problem.

    The result is the same. :(

    I have clearstate (few days ago) with remove state and remove data into the directorys...but the issue wasn't solved.

    Looking in MOS most times the solution is to de-install the agent, check if the host and agent still exist in OEM, If so drop them (Agent decommision). And install again.

    I uninstalled many times and reinstall agent without success.

    I obtain the same error.

    I checked with wireshark the trafic from OMS server and the agent. I saw "hello from server" and "hello from client". Trafic seems good (compare with another agent which is ok).

    I don't understand why it doesn't works with this agent.

    Found it (I hope). In my old (12c) documentation I found the same situation. In case of a almost empty targets.xml or it too many targets:

    On the OMS-server:

    emcli login -username=sysman ( or another super admin name)

    emcli sync

    emcli resyncAgent -agent="agent server fqdn:3872" If the agent is not blocked you may need to add -force, but I think this is not needed in 12c.

    emctl status agent will say:

    Collection Status                            : Collections enabled

    Heartbeat Status                            : Agent is blocked

    Blocked Reason   : Agent is blocked for resync job

    But after a few minutes all should be ok.


    Btw emctl status agent gives you the fqdn agent server name and not just agent I hope.

    Agent URL              : https://agent:3872/emd/main/

    Hello Eric,

    thank you very much for your help. I appreciate.

    You're alright, it's without FQDN. I can try to reinstall (with silent deployment installation) with FQDN.

    For OMS server and emcli, I obtain the following error (not configured maybe).

    Regarding the emcli command: It could be you have to use an other user: https://community.oracle.com/tech/apps-infra/discussion/3986573/emcli-configuration has the same Java errors.

    emcli setup may give you more information. I don't have an environment to check at the moment.

    Thank you Eric.

    I triyied to install emcli

    mkdir c:\emcli

    set JAVA_HOME=C:\Program Files\Java\jdk1.8.0_211

    set PATH=%JAVA_HOME%\bin;%PATH%

    java -jar c:\mypath\emcliadvancedkit.jar client -install_dir=c:\emcli

    cd c:\emcli

    set EMCLI_STATE_DIR=C:\emcli

    emcli setup -url=https://oms.server.com:7799/em -username=sysman -trustall -dir=C:\emcli

    password

    Error: Connection to the current OMS could not be established. Check the log files for further details.

    Log file location is : C:\emcli\.emcli\.emcli.log

    I have the following error :

    SEVERE: HttpConnectionException

    oracle.sysman.emCLI.omsbrowser.HttpConnectionException:

    javax.net.ssl.SSLException: Received fatal alert: close_notify


    I applied the following patch (The 12.1.0.5 OMS uses version 11.1.1.7.0 of FMW)

    https://support.oracle.com/epmos/faces/DocumentDisplay?_afrLoop=369784747529627&parent=EXTERNAL_SEARCH&sourceId=PROBLEM&id=1930390.1&_afrWindowMode=0&_adf.ctrl-state=f2auplkhq_140


    stop oms, applied the patch, restart (and reboot OMS server)

    I obtain the following error still

    I uninstall java jdk1.8 and install 1.6 (see on forum)..that's works ! (probably TLS issue previously...TLS1.0 using)

    C:\emcli>emcli sync

    Synchronized successfully

    emcli resyncAgent -agent=agent.fqdn.com:3872

    Error : Agent agent.fqdn.com:3872 do not exist

    I can see the list of targets (that's works !)

    with emcli get_targets

    (see for the agent whith issue...error measures collect)
