Home -> Community -> Mailing Lists -> Oracle-L -> FW: Is DATAFILE order important in CREATE CONTROLFILE?
Rich - I frequently clone our production database to test. Since the
location of the files is different, I usually end up editing the CREATE
CONTROLFILE in a major way, resorting the contents sometimes to the name of
the datafile and sometimes sorted to the location. We have about 200
datafiles. I have not experienced any ill effects from these changes, but it
never occurred to me that it might.

Jesse - No, order isn't important. This is a relational database after all -
right?

I'm writing a Perl script to automate the procedure to create a copy of an 8.1.7 production DB to a development server. Both production and dev are HP/UX 11.0.
In doing this, I've created a file that cross-references where the production datafiles are and where they are to be placed in dev. This works fine, but I also wanted to dynamically create the CREATE CONTROLFILE statement for the "new" dev DB.
I've noticed that the DATAFILE clause does not have the SYSTEM tablespace's datafile first, nor are any of the other datafiles in the same order that they are in production (e.g. from the output of an ALTER SYSTEM BACKUP CONTROLFILE TO TRACE). Does this matter? Does the order need to be preserved?
I suppose I'll end up dynamically creating the cross-reference file, which would preserve the order, but now I'm curious.
TIA!
