That's what I was wondering about. The default for
PDSE_HSP_SIZE|HSP_SIZE(nnn) is 0, and according to the Manual 0 disables
PDSE Member Caching.
"You can use the HSP_SIZE parameter to request up to 2047
megabytes for the PDSE hiperspace. You can indicate that the hiperspace is
not to be created by setting HSP_SIZE to 0. If the hiperspace is not
created, the system will not cache PDSE members.
On systems that are running in z/Architecture mode, by
default the PDSE hiperspace is not created and PDSE member caching is
disabled."
You need to specify something to get PDSE member caching. I'm just wondering
if this is tied to directory caching and buffer beyond close also.
I think the default of 2GB should be enough for Directory cache, but it
would be nice to know how your statistics support this.
