ORA-01127, ORA-01163 during database creation

In my earlier post i mentioned how to create/add another database in an existing server (http://www.chandu208.blogspot.com/2012/07/add-another-database-on-existing-server.html). Again today i'm creating new instance on an existing server and hit an error

ERROR: ORA-01127: database name 'RCDEV' exceeds size limit of 8 characters

CAUSE: The database name mentioned above exceeds the limit set

SOLUTION: change the database name to 8 or less characters

Then changed the name to 8 characters

Then error resolved

Now, running the control file script to create controlfiles for new database

SQL > @con.ctl

CREATE CONTROLFILE REUSE DATABASE "RCDEV" NORESETLOGS ARCHIVELOG

*

ERROR at line 1:

ORA-01503: CREATE CONTROLFILE failed

ORA-01163: SIZE clause indicates 12800 (blocks), but should match header 640

ORA-01110: data file 4: '/OPT/ORACLE/ORADATA/RCDEV/USERS01.DBF'

Vi con.ctl

CREATE CONTROLFILE SET DATABASE "RCDEV" RESETLOGS  NOARCHIVELOG

    MAXLOGFILES 16

    MAXLOGMEMBERS 3

    MAXDATAFILES 100

    MAXINSTANCES 8

  '/opt/oracle/oradata/ RCDEV/users01.dbf',                 ß Comma leads to an error

;

Then deleted that ‘comma’ and reran the con.ctl script then controlfiles have been created.
