0 (DB_KEEP_CACHE_SIZE is not configured by default)
Range of values
Minimum: 0 (values greater than zero are automatically modified to be either the user-specified-size rounded up to granule size or 4MB * number of CPUs * granule size, whichever is greater)
Maximum: operating system-dependent
DB_KEEP_CACHE_SIZE specifies the size of the KEEP buffer pool. The size of the buffers in the KEEP buffer pool is the primary block size (the block size defined by the DB_BLOCK_SIZE initialization parameter).
