Thanks to all who responded.
As I was driving in to work this am, I realized that in my table and index creations I had in fact placed each partition on it's own tablespace and I could make the tablespace READ ONLY and that would make the partition READ ONLY. I must have been really tired when I posted the question. It has taken me the most of 2 weeks to configure the datafiles, tablespaces, and tables correctly to eliminate fragmentation and size them correctly. Not easy to take a 70 GIG database and bring it over to a 2 disk test server.

Now I have to try and get the hardware to do backups.... Thanks Again.

alter tablespace <tablespace> read only;

Not sure if this is applicable to your situation, but I would consider it..

You can put all partitions that you would like to be read only in the read only tablespaces.

List,
I have implemented Local Managed Tablespaces and Partitioned my data and indexes by date ranges. The data contains dates from 06-1993 to present and is about 20 GIG in size.
The question I have is: Can some of the partitions of a table be made "READ ONLY" and some made "READ WRITE"? Each partition is contained in it's own datafile. I would like to back up the database and not have to backup the older data if I can.
I have read the confusing manuals and the cryptic options available list for the create tablespace, table commands and can't grasp the LMT,Partitions, Read Only command context. Any Ideas appreciated.
ROR mª¿ªm
