[mod.computers.vax] CTLPAGES

     Does anyone have a good understanding of what this SYSGEN
parameter does? I can't seem to find any discussion of it anywhere.
Nothing in uVMS or VMS doc, or online help. I have been told that raising
this parameter on MicroVAX workstations will prevent (or lessen) pool
expansion failures when the display manager is being heavily abused.
Is this true, and what penalty is incurred by raising it? And is there
any other related parameter that needs to be bumped when dealing with
this problem?


		Thanks,

CTLPAGES is the number of pages of P1 space to reserve for processes.  Such
pages are charged against your total number of pages just like P0 pages.
The cost is in extra pages in each user process, so you might want to
increase stuff like PGFLQUOTA and WSMAX.

VWS uses pages up in P1 space to store its data structures.
