Natural Buffer Pool with NAT v414

[Richard_Bryan]

I am about to migrate my production environment to NATURAL v414. In the Buffer Pool Parms I see “Method”. I don’t think this existed with v316. I intend to use the Buffer Pool Cache, and the documentation says that METHOD=N can be used with the cache. Is this the recommended combination? Any experience or recommendations appreciated.

According to the documentation: :lol:
http://servline24.eur.ad.sag/SecuredServices/document/java/nat414mf/ops_mf/bp_buff_0440.htm#METHOD_N

METHOD=N can especially be considered for large buffer pools in combination with the buffer pool cache function. For details, see also Choosing Search Methods below.
…
The advantage of METHOD=N is the short selection process and, usually, little browsing that require less CPU time for allocating space. This can be significant to large buffer pools.
…
The disadvantage of METHOD=N is that objects are selected less carefully for removal from the buffer pool. To avoid an increase in Adabas I/Os for reloading removed objects, we recommend that you use METHOD=N in combination with the buffer pool cache function.

:arrow: Therefore the answer is : Yes, especially if the buffer pool is large.

Michael,
Thank you for your response. However, your web site link did not work for me. This documentation you quoted is not in the documentation delivered with the product, is it?

Of course, this begs the typical questioin, "What is LARGE? :?

I decided to go with the METHOD=N because I did intend to use the BUFFER POOL CACHE.

Again, Thank you for your reply.

Richard,
Sorry for pasting the wrong link. My link points to an internal SL24. :oops:
We are going to provide the Natural documentation to the Community very soon. I am sure this will help many people.

With best regards,

Michael
