Sets the number of slices to use for a sliced database environment. The value provided here must be a positive integer. However, for any performance benefits to be realized through the use of slices, this value should be greater than 1. For best results, set this value equal to the number of available cores.

The syntax of this parameter in the DB_CONFIG file is a single line with the string set_slice_count, one or more whitespace characters, and the number of slices that you want to use.

If slice support is not configured for the database at compile time, then this parameter is ignored. In addition to this parameter, Db handles must be open with the DB_SLICED flag in order for the database to be sliced.

If the database environment already exists when this parameter is changed, it is ignored. To change this value after the environment has been created, re-create your environment.
