Hi Florian, If you are not using all tablspaces block sizes. I think you could try to create tablespace 16k or 8K or 4k for example (one you are not using), and thre create the table there, and only that table will use the blocksize_16k cache memory. Now if you have problems with redo logs, set as nologging. Honeslty I think you can get all what you want, the point is don't try to get the solution exactly as you want to find, there are other resources and tricks. -- //www.freelists.org/webpage/oracle-l
