Brief Description of Problem:

John has an AlphaServer 8400 with 8 GB of memory, but the applications
that they are developing are not able to malloc more than approx. 900 MB
of memory. How can they allocate more memory?

| 3332.1 | increase virtual memory parameters | HYDRA::DORHAMER | Mon Mar 17 1997 14:52 | 6 | |
I told John which parameters to set in the sysconfigtab file to
increase the virtual memory size available to user processes.
I will follow this up with a mail message to make sure that he gets
the correct spelling of these long parameter names.

Subj: Virtual memory parameters for Digital UNIX
John,
To follow up on our phone conversation, here is the list of entries that
you need to add to the /etc/sysconfigtab file on your Digital UNIX system
to increase the amount of virtual memory available to users. This example
sets maximum virtual memory to 4 GB. To set higher or lower values, scale
the number appropriately.
vm:
vm-maxvas = 4294967296
proc:
max-per-proc-address-space = 4294967296
max-per-proc-data-size = 4294967296
per-proc-data-size = 4294967296
Reboot the system after modifying the sysconfigtab file. You can check
the values by issuing the commands:
sysconfig -q vm
sysconfig -q proc
From a user account, use the c shell limit command to check on the size
of datasize and addressspace for that account. Issue the unlimit command to
increase the limits to the maximum values allowed (i.e. to get the max value
set in the sysconfigtab file).
Please call or send e-mail to [email protected] if you need any
further help. Please reference log number 1997-3332 if you need further
help for this particular problem.
