ORA-01034: ORACLE not available
 *Cause: Oracle was not started up. Possible causes include the following:
         - The SGA requires more space than was allocated for it.
         - The operating-system variable pointing to the instance is
           improperly defined.
 *Action: Refer to accompanying messages for possible causes and correct
          the problem mentioned in the other messages.
          If Oracle has been initialized, then on some operating systems,
          verify that Oracle was linked correctly. See the platform
          specific Oracle documentation.

ORA-27101: shared memory realm does not exist
 *Cause: Unable to locate shared memory realm
 *Action: Verify that the realm is accessible

Start the instance.
ALWAYS copy and paste ALL what you did and got.
