Hi
API Guide, page 211, Setting database properties,
TABLE 12. 5 Services API database properties arguments
isc_spb_prp_page_buffers
"Set the default number of cache buffers to the
specified number; corresponds to gfix -buffers"
and
API Guide, page 208, Services API restore arguments,
TABLE 12. 4 Services API database restore arguments
isc_spb_res_buffers
"The number of default cache buffers to configure
for attachments to the restored database;
corresponds to gbak -buffers"
(BTW, isc_spb_prp_page_buffers equals to 5, where
isc_spb_res_buffers equals to 9)
Is correct to assume that isc_spb_prp_page_buffers
and isc_spb_res_buffers refer to the same thing?
BTW, are cache buffers the number of page-sized buffers
the engine should allocate for servicing each client app
attaching to the database?
If yes, is that number automatically increases when
a need arises? Or the defined number functions as
an upper limit?
Regards
Theo
