I suggest checking the following:
- Verify that there is a listener running for this database. It should listen on the host, port, SID/SERVICE_NAME found in the value of the oracle.sysman.eml.mntr.emdRepConnectDescriptor parameter in the emoms.properties file, which is located in <db_home>/<host>_<SID>/sysman/config directory.
Sample parameter value:
- Verify that you can connect to the database using sqlplus over Oracle Net on the host, port, SID/SERVICE_NAME set in the above-mentioned parameter.
Listener is started and I can log into SQL without issue.
Where exactly are you getting this error about EM being "non-secure"? Can you login to EM? Are targets uploading?
