contiguous memory

[VINCENT SPURGEON]

I am wondering if there is a utility that will display available contiguous memory pages vs non-contiguous pages HP-UX 11.11? Any ideas would be appreciated. Thanks.

Vincent,

Did you already tried with one of those tools: shminfo, seminfo or kmeminfo

They are unsupported tools from HP, you can always open a case with them and request them the utilities, they might give you the info that you are looking for.

Regards,

Jaime.

Your question is ambiguous because there are so many different parts of memory. The kernel has it's own memory, shared libraries occupy RAM, shared text (program) areas occupy memory, each process has a private data and stack area in RAM, some processes use shared memory and almost all processes use the buffer cache.

Technically, memory is hardly ever contiguous. Each program has memory pages that appear to be contiguous but are physically scattered all over RAM. About the only memory area where a contiguous segment is required is for shared memory and then only for 32bit programs.

Yes, it was an ambiguous question. However, I've discovered what I was looking for. Thanks for your help.
