SubsetElementBreatherCount

This parameter manages the way IBM® Cognos® TM1® handles locking behavior for subsets.

Parameter type: optional, dynamic

When

SubsetElementBreatherCount=-1

The Cognos TM1 server never releases the lock on subsets when other requests for the subset are pending. This setting is the default. It can optimize view performance for a single user, but at the cost of multi-user concurreny.

When

SubsetElementBreatherCount=0

the Cognos TM1 server releases the lock on subsets when other requests for the subset are pending, then reacquires the lock after pending requests are processed. This setting improves performance when multiple users attempt to access the same subset, particularly when the subset contain more than 100 elements.
