    Discovery of node failing ..plz help!!

    Well i created couple of separate database using DBCA without oracle
    jvm, multimedia, example db, xml db coz for our databases we did not
    need it. Now to manage those databases i use EMC but to take backups
    or restore or export import the emc has to be opened in OMS mode so
    for that i created a separate database OEMREP using emca and now when
    i start the emc in oms mode and then it comes up with discover node
    wizard and i enter the host name even the system full ip add. where my
    databases are but it still gives me an error saying cannot find node ,
    intelligent agent not running. so i go to prompt back and try to start
    the agent using agentctl start but it fails to start. when i see the
    log it says failed while initializing SNMP. Can someone plz help me as
    i need to try to run hot backups for my databases. Plz tell me what am
    i doing wrong or what do i need to do or check. We have aix 5.1
    operating system and oracle 9i (9.2.0.5). Hope to hear from you soon.
    Thanks a lot in advance.

          Hi,
          I did the same thing but ofcourse there were no .q files there..But i
          removed the ora and ver files and tried to start the agent but i got
          this msg again..

          Starting Oracle Intelligent Agent...
          Agent startup failed. Check
          /exlibris/app/oracle/product/920/network/log/dbsnmp.nohup for details

          Plz help me on this so that i can somehow start this thing and start
          using my EMC to try to take backups export and all that which can be
          done only in oracle management server mode.
          Thanks,

              It would be useful to post the content of both dbsnmp.nohup and nmiconf.log.

              Make sure your listener.ora has the SID_DESC entry for the database you want
              to register.

                  The last assertion is definitely not true. Command line backups and
                  commandline exports have existed 4ever and they work. The Management
                  Server doesn't add that much functionality to it, except for a job
                  history and nice icons ;-)

                  Actually you should do as pointed to by the error message, get vi or
                  pg and open up
                  /exlibris/app/oracle/product/920/network/log/dbsnmp.nohup

                  Likely it will contain error messages and/or warnings.
                  Post them and I will try to help you out.
