Problem Autodiscovery of node from Enterprise Manager

We are using Oracle Enterprise Manager 2.1.0.1.0 through Management Server on NT for Oracle 8i(8.1.6) on Linux
While autodiscovery of node from Enterprise Manager I am getting following
error
"Discovery Failed VNI-4002:Unknown gateway Exception"
Even Intelligent agent and all the requisite services are started.
If we configure manually we will get
following error while using the tools of management pack
"VTO-2018 This wizard Couldnt be launched because target was manually
configured.It can only be launched for targets which have been discovered using an Intelligent Agent."
I shall be thankful if you provide the solution ASAP
Thanks

Are you grant LOG ON AS AN BATCH job to OS USER.
OR

  • Error deploy shared library from Enterprise Manager IAS10.1.3.5.0

    Hi,
    I am trying deploy one shared library in my OC4J instance (prd_oc4j) from Enterprise Manager, but when i run my application its not loading this library (error missing class), but when i put this shared library in file server.xml without Enterprise Manager my application run sucessfully.
    Help me please or this problem is a bug?
    Tks,

    If finally found the cause of the problem, lack of PermGen space for the home instance;
    When opening the EM Console most of the times i was able to open the login page, under stress opening this page failed most of the times.
    The ascontrol-application.log pointed me in the right direction;
    10/09/07 15:26:59.111 ascontrol: Servlet error
    java.lang.OutOfMemoryError: PermGen space
    When monitoring the PermGen of the home instance, is showed that the system was running out of PermGen space.
    Increasing the PermGen size for the home instance in opmn.xml did the trick

  • Can't do anything from Enterprise Manager

    I am trying to undeploy an application from Enterprise Manager Web Site, and I get the following error:
    An error occured while undeploying the application. The configuration files for this Oracle9iAS instance are inconsistent with the configuration stored in the repository. In order to protect the repository, no further configuration or deployment operations are allowed until the problem with the configuration on the filesystem is resolved. This condition arises when a prior operation was unsuccessful. Please check the logs located at ORACLE_HOME/dcm/logs to determine why DCM was unsuccessful in updating the configuration files on disk. Some possible causes are: * permissions on files * file contention issues on Windows NT * EMD and dcmctl running concurrently * internal Oracle error After resolving the problem that prevented DCM from updating the configuration files, you may use the dcmctl resyncInstance command to resolve the problem. Alternatively, you can stop and then restart the active dcmctl or EMD process and resyncInstance will automatically be performed.
    It won't let me do anything. I tried dcm, too. It happens too often to me that I cannot deploy or undeploy apps from EM, or even to alter simple properties. Is there a way to recover from this situation?
    I have checked the errors at $ORACLE_HOME/dcm/logs but I can't get any ideas from there.
    Help me

    check out the Application Server - General forum. this has been discussed quite many times. Specifically,
    9iAS instance out  of sync with Repository

    If i understood correctly what you are trying to ask , you are interested in email notification when your node suddenly reboots/restarts.
    And if it is so, this is will not be possible in the way like it is for tablespace, memory and similiar alerts.
    Although you could consider monitoring alert.log content, because information about database up-down statuses can be found there.
    For example , you could do that either by using external tables or by using shell/batch scripts;depending on the os on what your database is, and then after information that indicates database unexpected reboot is found, forward that information further (e-mail notification) .

  • How to avoid timeouts from Enterprise Manager/BPEL console?

    Occasionally I want to deploy (from JDev) some BPEL processes to the AppServer.
    Surprisingly I got some errors. I found out when I re-login into
    Enterprise Manager and tried again to deploy it everything works fine.
    So it seems to me all errors occur because of a forced logout from Enterprise Manager.
    How can I avoid such situations?
    Peter

    Hi peter,

  • Error messages from Enterprise Manager Grid control

    Hi,
    Hi,
    I get several messages in my email daily from Enterprise Manager that Services from Application server control are down when all ther services are up and running. Messages like
    EM Alert: Critical: testdev - The OC4J instance is down.
    Any idea why this is happening.
    Thank You

    Here is the error in the "installActions<date>.log" file:
    SEVERE: OUI-25031:Some of the configuration assistants failed. It is strongly recommended that you retry the configuration assistants at this time. Not successfully running any "Recommended" assistants means your system will not be correctly configured.
    1. Check the Details panel on the Configuration Assistant Screen to see the errors resulting in the failures.
    2. Fix the errors causing these failures.
    3. Select the failed assistants and click the 'Retry' button to retry them.
    I checked in the details section and it listed this as the issue:
    Configuration assistant "OMS Configuration" failed
    The "D:\oracle\product\10.1.0\agent10g\cfgtoollogs\configToolFailedCommands" script contains all commands that failed, were skipped or were cancelled. This file may be used to run these configuration assistants outside of OUI. Note that you may have to update this script with passwords (if any) before executing the same.-----------------------------------------------------------------------------
    How do I fix this?? When I open up the configToolFailedCommands file, all it lists is "oracle.sysman.emcp.agent.AgentPlugIn".

    Oracle AWR can collect information about these.
    "The Automatic Workload Repository (AWR) is an integrated part of the Oracle database server. Its purpose is to collect server-related performance data automatically every 60 minutes (by default) when the statistics_level parameter is set to 'typical' (or 'all'). As the data is collected by the server itself, the Automated Database Diagnostic Monitor (ADDM) component of the server uses this data automatically to diagnose performance issues."

  • Backup problems from Enterprise Manager Database control

    I'm having a problem with performing backups from EM DB Control on two of my Oracle 10g 10.2.0.4 systems. When I configure and submit any backup job from EM (either online or offline), the following happens:
    - When the job is due to run a Pre backup task has status of 'Scheduled'
    - Prebackup task completes and status changes to 'Succeeded'
    - Backup task appears with status of 'Scheduled' and value of started time within the next minute
    - Status of backup task never changes from 'Scheduled', and the started time keeps updating to the current time
    - This goes on indefinitely until I abort the job
    At the moment I have scheduled tasks configured to run an RMAN job every night, but I need to get this working through Enterprise Manager Database control. Please help!
    Something else which has happended on one of these systems is that after applying some Microsoft Critical updates the database control service would not start. The only way I could find to resolve this was to recreate the Enterprise Manager repository. Could there be a link here at all?
    Cheers,
    Strak

    I think Rodney may have the cause, because the database has been copied. I have looked in every property file I can think of, and then all the rest anyway, and there is no reference to the old host name. And I have ralready e-installed EM using emca -config -dbcontrol db. And I'm definately on the correct port.
    So it must be held internally in the database. I've seen partial instructions on deleting the EM repository in the database & java files, does anyone have a full set I can use ? Once that is done, does emca reinstall everything ?
    Many thanks, Duncan

  • Problem with login using Oracle Enterprise Manager

    I am new to Oracle. I installed the software (my Operating System is Windows XP) and created a database following the guidelines in the documentation and Oracle By Example. Now I can not log on as the user SYS through the Enterprise Manager. However, I can login through SQL Plus. I am using the password that I assigned during the installation.
    In OBE, I got stuck at the step where you check the status of (or start) the dbconsole. I went to the DOS prompt and typed:
    emctl status dbconsole
    I got the error:
    Environment variable ORACLE_SID not defined. Please define it.
    If anyone can explain what the problem is, I'd appreciate it.

  • Serious problems deploying web application with enterprise manager

    Hi all,
    First I have to say that this thing that has happened to me today is freaking bizarre... I was trying to make a new deployment of a web application on OAS 10.1.2, using the Enterprise Manager. The application is using Spring and DWR, therefore it has some XML files included. The application worked perfect in JDeveloper 9.0.4, our development tool, and I've previously developed very similar applications in the past, and deployed them on the same server without any problem.
    Today, when I was trying to deploy my .ear file, I got this error message:
    The file specified, "FindAnExpert.ear" is not a valid ear file.
    I tried with the .war file, and this happened:
    Base Exception:
    java.util.zip.ZipException
    invalid END header (bad central directory offset). invalid END header (bad central directory offset)
    I checked that all the included .jar files were fine, I even replaced them with new ones. I started to remove files from the .war file and discovered that without the XML files I was able to deploy the application. Then I copied over those XML files through FTP and the application is working correctly, but I was not able to use the Enterprise Manager to deploy it!!! The XML files are well formed, on of them contains the details of a data source that I also reviewed to be sure that it was correctly configured... This is nuts... any ideas over there???
    Thanks in advance,
    Luis

    Luis,
    If all of the files uploaded piecemeal worked fine, then I believe your problem to be with your deployment descriptor(s). Also, note that the .war file lives in a different directory:
    C:\oc4j\j2ee\home\applications\Application-Name
    Perhaps if you have time you could post all of the associated deployment descriptor files. Log files from the C:\oc4j\j2ee\home\log\oc4j directory would also help to troubleshoot your deployment issues. You can turn up the logging level to "FINEST" for maximum output to your log file.

  • No action when trying to login a user from Enterprise Manager!

    Hi guyz,
    I have created 10g database on windows server2003, I have configured Enterprise manager but unable to login from EM.
    The EM service running fine, and the login page is also coming, but when I gave the username & password with the connection string and hitting the "Login" button there is no action.
    The database is up and running, listener is also running, I am able to connect from the command prompt, the emctl status dbconsole says EM is running. Initially I thought the EM configuration had some problems then I dropped the EM repository and recreated it, still unable to login from EM. Any suggestions??
    Thanks & Regards.

    No, not even as SYS user, initially the "Login" button was not working, whenever I pressed the login button there was no action, later I changed some of the Internet explorer settings, like changing the ActiveX scripts to enable, etc. Now the "Login" button is working, but even if I give the correct password, it is saying that username or/ and password is wrong.
