Cannot create controlfile

[sricky]

Hi guys,

In my shop I have to move the prod database to a new instance everyday so that people can generate report from the new one instead of pestering the prod database.
I have been using the create controlfile script I got from backup to trace and so far it was working well until yesterday night. I got an error like this when I created the controlfile using the script I modified to cater to the files location changes.

STARTUP NOMOUNT
CREATE CONTROLFILE REUSE DATABASE "ORS" NORESETLOGS NOARCHIVELOG

then I got the error like this after I run the script in nomount state.

ORA-1503 - Create Controlfile failed
ORA-1192 - Must have at least one enabled thread

Anybody familiar with this phenomena?

Thanks in advance.

ORA-01192 must have at least one enabled thread
Cause: At least two redo log files from at least one thread must be specified in the CREATE CONTROLFILE command line.
Action: Find the missing redo log files and retry the command with the newly found redo log files included in the command line.

It seems there were some error happened when os created the redo logfiles.

Why not to try use Replication, Standby DB, or Cold Backup (assuming with same directory structure)?

There appears to be a problem in Redolog file creation. Are the redolog files which u used for creation r correct or not. Once check up all redolog files
