You can set this parameter only when DB_BLOCK_SIZE
has a value other than n
K
. For example, if DB_BLOCK_SIZE
=4096
, then it is illegal to specify the parameter DB_4K_CACHE_SIZE
(because the size for the 4 KB block cache is already specified by DB_CACHE_SIZE
).
Do not set this parameter to zero if there are any online tablespaces with an n
K
block size.
Operating system-specific block size restrictions apply. For example, you cannot set DB_32K_CACHE_SIZE
if the operating system's maximum block size is less than 32 KB. Also, you cannot set DB_2K_CACHE_SIZE
if the minimum block size is greater than 2 KB.
