All -

I am not quite sure why, but all of a sudden, my database stopped working (8.1.5 on Solaris 7) and now I get error ORA-01034 when I try to run:
%>sqlplus username/password@servicename

I have tried setting TWO_TASK, increasing virtual memory, restarting the database, and restarting the machine.

I also noticed that in listener.trc, I get the following message whenever I try to connect:

nstimarmed: no timer allocated

I am not sure if this is significant, but am now out of ideas. Any thoughts?
