We plan to upgrade memory (128 mo -> 256 mo)on our vax 6000-510 (vms 6.2).
Is there any particular actions to do after inserting the new memory or VMS recognizes and uses it automatically?
Thanks in advance for your help.

Re: Memory upgrade
I am not aware of any special actions that you would be required to perform after you upgrade the memory. Just need to power down make the replacement and then boot up the system. Once the system is up, i would advise that you do the following
1. show mem/full
(Make sure that the memory is 256MB)
2. Run AUTOGEN
As the memory has changed, i think it
is never bad to run Autogen.
Let me know if you have any specific questions
regards
Mobeen

Re: Memory upgrade
If I recall correctly, starting with V6.0 or V6.1, VMS will automatically use the full amount of memory. You should still run AUTOGEN, so that VMS can adjust other memory-related parameters.

Re: Memory upgrade
It's the other way around. Pre V6 OpenVMS would automatically configure all available physical memory on any reboot. Post V6 you need to run AUTOGEN to make the operating system sees the extra memory after an upgrade. It was a consequence of adding support for larger memory VAXes - The maximum value for PHYSICALPAGES was increased. Old behaviour was to default PHYSICALPAGES to the (then) maximum value. New behaviour is for AUTOGEN to set PHYSICALPAGES to the amount found at the time it's run.
