Question : Oracle shared memory realm not found

First off, please pardon my ignorance of the intricacies of Oracle administration.  At one point we had a real DBA, but no longer.  We have 2 Linux servers running Oracle 9.2.0.  on our primary server, we have 2 databases available, one for production, and one for a demo site.  On the other server we keep our development database.  I am able to connect to production and demo through SQL Plus Worksheet, but not our development database.  The connection fails with the following error:

ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Linux Error: 2: No such file or directory

JDBC connections do not work either.

Strange thing is, this server was up and running just yesterday, and I have made no changes.  As I stated above, I know very little about Oracle administration, and have no idea where to start looking for a solution to this problem.  Any suggestions would be appreciated.
