Re: newbie : Oracle8i Authentification error

From Metalink;

Goal: To provide a checklist for troubleshooting a VNI-2015 error.

Fix: When scheduling Jobs or Events through the Enterprise Manager 2.x Console, the Oracle Management Server takes the request from the Console and submits it to the Intelligent Agent on the target server. The Intelligent Agent attempts to establish a "new" Operating System (OS) logon session for each job that it receives. The OS logon credentials are pulled from the Console's Preferred Credentials settings. In the Preferred Credentials section, each discovered service is listed along with its service type. For OS logons, the " NODE " service type must contain a valid OS user that has the correct permissions. If the logon information provided to the Intelligent Agent is incorrect or missing, the Intelligent Agent will return the error:

    VNI-2015: Authentication ErrorTroubleshooting Checklist

--------------------------The VNI-2015 error can occur for several reasons.

EM Console:===========

Begin troubleshooting the VNI-2015 error at the EM Console.

1. Verify the logon credentials for the target Node and target service have been set correctly in the Preferred Credentials section of the EM Console. If the Preferred Credentials are set correctly for the target node and the target service, continue troublshooting at the target server: Windows NT and 2000 servers:============================
2. Verify the OS permission 'Logon as a Batch Job' has been granted to the OS (NODE) user stored in the EM Console's Preferred Credentials section.
3. If the OMS is in a different NT domain, verify the domains can communicate.
