Hello Ronny

Maximum value for WSQUOTA is 65536. This is documented in the System Management manual (I only have VMS v7 documentation available but I expect that this value hasn't changed for v7)

From the help in Authorize (VMS 7.3):

MODIFY

/WSQUOTA

/WSQUOTA=value

...

The value cannot be greater than the value of WSMAX and cannot
exceed 64K pages. This quota value replaces smaller values of
PQL_MWSQUOTA.

WSQUOTA is the max amount of physical memory a user process can lock. With 65536 you can lock 33Mb for every process with actual page size.

The 33 MB are the value for the VAX (512 byte Pages) on Alpha this should be 512 MB (8k Pages)

Dear Martin,
I believe page size is 512 byte.
Reading SYSMAN value on AXP, system say pagelets for param WSMAX but AUTHORIZE say pages for WSQUOTE.
How much is page size on AXP?

Hi
There is a SYSGEN Parameter WSMAX who limits this WSQUOTA. Try changing this SYSGEN Parameter ...
Best regards

Hello,
Page size is 512 byte always.
Look for VMS operating system documentation;
- OpenVMS System Manager User Manual;
- Chap. 7: management user account
- System resource
- Understanding Pages and Pagelets.

To change WSMAX
>MC SYSMAN PARAM SET WSMAX 65536

Then you can change user WSQUOTA

Exceed WSQUOTA could not be a good idea. I prefer assign more virtual memory to user modifying PGFLQUOTA; naturally your system have sufficient virtual memory. See documentation about NPAGEDYN, NPAGEVIR, PAGEDYN, VIRTUALPAGECNT params.
Warning: theese params are very dangerous.

Hi Ronny,
I checked 4 U changind WSQUOTA on a old AXP 400.

First, I modified SYSGEN param WSMAX. System accept value greater then 65536 because on AXP you can assign 65536 pages; value is written in pagelets that are 4, 8, 16 or 32 times page. On my system, 1 page = 16 pagelets. If I'll write 1048576 system accept; no greater value is accepted.
Note the modify in SYSGEN o SYSMAN is not correct procedure to modify a system parameter, but I will a direct response from system.
Now I wrote 1048576 and I've rebooted the system: the value is above the physical memory and on bootstrap system correct my value leaving a value greater then 65536.
I don't changed a value with AUTHORIZE and I think system accept any value less then WSMAX.
Now I restored original value of WSMAX.

Bye
