SYSCS_UTIL.SYSCS_EMPTY_GLOBAL_STATEMENT_CACHE

The SYSCS_UTIL.SYSCS_EMPTY_GLOBAL_STATEMENT_CACHE stored procedure removes as many compiled statements (plans) as possible from the database-wide statement cache (across all region servers).This procedure does not remove statements related to currently executing queries or to activations that are about to be garbage collected, so the cache is not guaranteed to be completely empty after it completes.

The related procedure SYSCS_UTIL.SYSCS_EMPTY_STATEMENT_CACHE performs the same operation on a single region server.
