Hi Joe,
Are you trying to recreate a controlfile or ??
What are you trying to archive?
You do :
alter database backup controlfile to trace;
ANd it generate a trace file in your udump subdirectory:
and look like this right??

- Usually I copy this trace file to recreate-controlfile.sql
- delete all the lines until
"STARTUP NOMOUNT"
And you have to see what you like to do?
You might have to change
"CREATE CONTROLFILE REUSE DATABASE "DDDTEST3"
NORESETLOGS ARCHIVELOG"
"
CREATE CONTROLFILE SET DATABASE "DDDTEST3"
NORESETLOGS ARCHIVELOG"
It depend what you hope to archive.
3) I usually
sqlplus "/ as sysdba"
startup nomount
@recreate-controlfile.sql
Then you will create new controlfile.
Is it what you hope to test??
