Abstract
For an information retrieval system coupled to a buffer pool maintaining a plurality of pages of recently accessed information for subsequent re-access, a technique for starting the buffer pool is provided. The technique facilitates a quicker start to the buffer pool by deferring allocation of page storing portions, for example, until they are needed. The technique makes the buffer pool available for storing pages while deferring allocation of a page storing portion of the buffer pool and allocates the page storing portion of the buffer pool in response to a demand to store pages to the buffer pool. The technique may be used to re-start a buffer pool with pages stored to a memory coupled to the information retrieval system where the pages where stored upon a buffer pool shutdown. Further, buffer pool readers or prefetchers may be configured to read pages for storing to the buffer pool and allocate the page storing portions of the buffer pool in response to instructions to read particular pages.
