Hello, after a startup attempt please post the output of the following command:
netstat -tulpn | grep 1521

And include the relevant part of the
/u01/app/oracle/diag/tnslsnr/term1/listener/alert/log.xml

And
 /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
would be interesting as well.

Plus give more details about your OS.

I'm never a fan of using hostname in the Oracle config files.  I always prefer using the IP address.

Check /etc/hosts for term1.localdomain.  Odds are the issue is there.

is your database started?

run

>ps -ef | grep pmon

to see if your database is running

and also run

>lsnrctl stat

to check your listener

>>is your database started?

What does that have to do with the listener not starting?

>>to check your listener

That is sort of the reason for the question...  It isn't starting so the status will show nothing.

[oracle@term1 dbs]$ netstat -tulpn | grep 1521
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)

walkerdba, what about the rest of the information we requested?

All that netstat command does is show nothing has port 1521 open.  That was sort of given since the listener isn't starting.

Please check /etc/hosts for an entry term1.localdomain.  If it isn't there, add it or change the listener.ora to use ip address instead of hostname.
