After add-on memory

Hi
If I add-on memory from 2GB to 4GB in my host, should I modify the kernel ? How to do that?

Thanks

I don't think the kernel needs to be modified. Booting should be enough.

Re: After add-on memory

Hi,

that's right. If the memory is supported and you see it with show mem on console prompt there is no need to build a new kernel. You may however check system values whether you want to adjust them.

Re: After add-on memory

check binary.errlog for memory problems to be sure memory properly works

Re: After add-on memory

Rambo,

Also check if the following parameters in /etc/sysconfigtab still make sense after the memory add-on. You might want to increase some of them to make better use of the new memory.

proc:
per-proc-address-space
max-per-proc-address-space
per-proc-data-size
max-per-proc-data-size
per-proc-stack-size
max-per-proc-stack-size
max-proc-per-user

Regards,
Ross
