sp_cacheconfig includes the instance instance_name parameter so you can create, drop, or modify the size of a cache on a specific instance.
sp_cacheconfig "[cachename [,cache_size [P|K|M|G]" [,logonly | mixed ] [,strict | relaxed ] ] [, "cache_partition = [1|2|4|8|16|32|64]"] [, "instance instance_name"]
where instance_name is the name of the instance whose cache you are adjusting.
This example displays the cache for instance blade1:
sp_cacheconfig 'instance blade1'
This example sets the size of the Sales Cache size on blade1 to 100 megabytes:
sp_cacheconfig 'Sales Cache', '100M', 'instance blade1'
This example sets the size of the Sales Cache size on blade1 to 0 megabytes, effectively dropping the cache.
sp_cacheconfig 'Sales Cache', '0M', 'instance blade1'
This example displays the cache configuration for the entire cluster:
sp_cacheconfig
If you do not specify an instance_name, the cache for the cluster is displayed.
