On-Heap Cache
On-heap cache is the portion of a cache that resides within the heap of the JVM where the Integration Server is running.
On heap-cache is fast, but because it resides within the heap space, it is subject to the garbage collection process. For large caches, the garbage collection process can cause lengthy interruptions during the execution of a service. If the heap is large, the interruption might be multiple seconds.
Note: The amount of memory that you can use for on-heap caching depends on the amount of memory you can allocate to the JVM heap. This limit varies according to the JVM, the machine, and the operating system that you are using.
Out of the box, Integration Server supports the use of on-heap caches. You do not need an additional license to create and use an on-heap cache.
For more information about using an on-heap cache with Integration Server, see Configuring an On-Heap Cache.
