Hi Kalpana,
You should cross-check your Oracle SID / HOME to make sure that these are valid.
Also if you are on windows you should cross-check to make sure that the service is started.
For further analysis have a look in the alert log and also cross-check your database init file to ensure that the entries are correct.
If these don't help check out metalink as there are plenty of hits on ora-27101.
Cheers
Keith

Subject: ORA-27101: shared memory realm does not exist
Hi DBAs,
I am confronted with the following error.
The database is not starting up.
ERROR:
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Please help me immediately.
I am hoping there is a solution to get out of this, since I do not have
back ups for a few schemas in the database.
Regards,
Kalpana.
