HPUX Command to print page of memory in bytes

Eddie Salvatierra — Tue, 08 Nov 2005 20:27:57 GMT

Hi..

On Solaris there is a command called pagesize which prints the size of a page of memory in bytes. Is there an equivalent command on HPUX 10.20 11.00 and 11i. ???

Cheers

Default page size on hpux is 4096 bytes, it's viewable w/ dmesg output. Also have a look at this thread for more info

In HP-UX, there is a general information command called getconf which can query dozens of system values. man getconf will provide the details.

One other note: starting with 10.20 on PA-8000 processors (or higher), the page size for individual programs can be variable, 4k up to 64megs. Large page sizes are commonly used with extremely large programs that manipulate and compute massive arrays of data. A large pagesize will reduce the number of times the memory address translation registers (TLB) need to be reloaded during program execution.

Hi:
The memory page size is defaultly as 4KB, but sometimes it can be 8KB or others.

In /var/adm/syslog/syslog.log you can see the boot information , where you can also see the real page size for memory on your server.

Here's the HP-UX equivalent:

# getconf PAGE_SIZE

You can use sam to get these details as,

sam -> performance monitor -> system properties -> Memory Tab

will give all details.
