OVMAPI_6000E Internal Error: Connection refused Connection refused - OVM

Question

Hi,
Test environment, as per this doc
http://www.oracle.com/technetwork/server-storage/vm/template-1482544.html
Running the above OVMs on virtual box version 4.2.10
OVM is version 3.1.1.365
I setup my environment and was ready to import VM templates. Following a reboot of the server I can no longer login to the Manager.
Error is: Unexpected error during login (com.oracle.ovm.mgr.api.exception.FailedOperationException: OVMAPI_6000E Internal Error: Connection refused Connection refused
After some investigation in the App logs I found this error:
ORA-12505, TNS:listener does not currently know of SID given in connect descriptor
(------------- lsnrctl service shows this ----------)
LSNRCTL for Linux: Version 11.2.0.2.0 - Production on 20-APR-2013 22:58:31

The command completed successfully
(-----------) - This is just a test environment, but I would really appreciate if someone could tell me why this error is occurring and how I can fix it, I've tried restarting services, still no joy. This issue seems to occur after I setup the server pool \ Storage resources, etc
Thanks for all your help!

Answer 1

You need to learn how to start an oracle database. The database does not start automatically if you're using the database that comes with the VM Manager.
ps -ef | grep pmon
will tell you if the database is running and mounted.
ps -ef | grep tns
will tell you if the database listener is running
OR
You could use 3.2.2 and use the MYSQL database that come with the VM Manager
OR
you could load the enterprise version of Oracle Database and use cluster services to automatically start and stop the database. You get a single use license with the VM Manger that allows you either use standard of enterprise edition of the Oracle Database.
