You created or tried to create UNDOTBS undo tablespace in your create database and your parameter "undo_tablespace" is set to UNDOTBS1.

ORA-30012:	undo tablespace 'string' does not exist or of wrong type
Cause:	the specified undo tablespace does not exist or of the wrong type.
Action:	Correct the tablespace name and reissue the statement.

Quote:

undo tablespace 'UNDOTBS1' does not exist

and ,

Quote:

CREATE UNDO TABLESPACE UNDOTBS

See the difference

1. open your pfile (init<sid>.ora) file and change undo_tablespace parameter to UNDOTBS.

2. Recreate your spfile file from pfile file.

3. shutdown immdiate;

4. startup

You can also directly change your parameter file (spfile) while in nomount mode with "alter system".

SYS> startup nomount
ORACLE instance started.
Total System Global Area  314572800 bytes
Fixed Size                  1290352 bytes

SYS> alter system set undo_tablespace=undotbs scope=spfile;

System altered.

SYS> alter database mount;

Database altered.

SYS> alter database open;

Database altered.

SYS> select status from v$instance;

OPEN

1 row selected.

Spfile can be accessed as soon as the instance process is created that is before mounting the database.
Hopefully as this is the only way to start when you have no configuration file (init.ora) and scramble your spfile.

You can create a pfile (initSID.ora) file manually using the contents from the alert_SID.log file which contains non-default parameters & their values (as shown at time of last DB startup).
