refresh enterprise manager with new databases from tnsnames.ora

[TheDash]

Hi,

I have added new databases to tnsnames.ora but they are not seen in enterprise manager, how can I refresh the enterprise manager 9i db console with latest tnsnames.ora file? I am using the 'logging to oracle management server option'. I tried to discover nodes but that didn't work. In standalone mode I could add databases to tree, however standalone mode doesn't allow me to anything...

All I am looking for is to add new databases in an updated tnsnames.ora to enterprise manager database console (not grid console) so that they can be monitored.

Thanks for providing any steps/help in advance.
