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

A few options. Do you use RMAN for backups? , if so duplicate the database and rename the files as part of that process.

Otherwise clone the database by copying the files at the o/s level and change the instance name. Several documents on metalink show how to do this.

If you have used an OFA setup then renaming the datafiles should not be that difficult, it will only be the directory named after the sid that willl need changing

On a database that size export would take some time but it is another option.

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
