Transactional Cache size update via Caches Tool

[AFaust]

FEATURE / ENHANCEMENT

The Caches Tool should support the ability to update the maxCacheSize property at runtime (without persistence of the changed value) to allow for potentially temporary alterations to the limit without requiring a restart. This may be useful in debugging sessions or regular use to avoid the Transactional update cache is full log warning and associated purge of the shared cache. Instead of guessing the appropriate value over multiple restarts and tests, this ability may help in pinpointing the value in a real, running system without interuption of service.
