You can set a buffer pool size to allocate the total amount of memory, in kilobytes, available for caching table, index, and dictionary files. A buffer pool size can range from 16K to 131,072K. The value of BP(0) sets the buffer pool size for data, and the value of BP(1) sets the buffer pool size for indexes. However, if you set BP(0) to a value of zero, this sets the buffer pool size to zero for both data and indexes.
Micro Focus's buffer management system is designed to enhance performance. Memory is allocated by the cache manager at XDB Server start up and then released at XDB Server shut down.
