Title: How to move 200 GB db from prod to dev?

Helmut,

 

Why can't you simply copy the files and then re-create new control files?  This gives you the option of renaming the database.

 

Not sure what your backup procedures are, but you could always restore a backup to the development box and, again, recreate the control files renaming the database as you go.

 

Hope this helps

Hi!

We are supposed to clone our production database onto a new development box (both boxes are Sun Solaris). The db is about 200 GB in size.

What would be the best way to achieve this? Simply copying over the files won't work, since the instance names are different:

Production:  SID=PCLDB1 => e.g. /u02/oradata/PCLDB1/system01.dbf
Development: SID=ROLAND => e.g. /u02/oradata/ROLAND/system01.dbf

So would export/import the entire db be the only way? (But writing out dump file that big should be a little disk space problem...)

Renaming all the datafiles (approx. 100) would be kind of annoying...

Any ideas?

This is 8.1.7 on Sun Solaris.

Thanks,
Helmut
