Hi,
I have noticed that our database is configured to extend SMS tablespace objects by one page at a time. (Multi page file allocation enabled -NO).

We have mix of SMS and DMS tablespaces and the DB size is over 500GB.

Is it important to enable the Multi page file allocation ? should be able to see any better performance? finally how can I enable this ? once i have enabled this is it possible to backout ?

Thanks, Gunas

Multipage file allocation can be enabled using db2empfa 7 for databases that are created after the registry variable DB2_NO_MPFA_FOR_NEW_DB has been set.

Multi page allocations have the advantage that only a single operation is needed instead of multiple separate operations. Especially if you have lots of INSERTs that require new pages, you may notice a performance difference.
