I'll be setting up a new NT server with ASE 11.5 soon and
am curious what other folk are using for NT paging file
sizes.

The box is 4 way SMP with 2GB RAM. The apps on it
are OLTP with occasional online reporting, with a
user count of about 100, expected to go to
around 300.

I'm looking at a size of about 300MB to start.

TIA,
Gary

Hi Gary,

Sybase shared memory is mapped to the paging file on NT. This means that
your page file must be at least the size of the shared memory Sybase is
using. If there is insufficient page file available, Sybase will fail to
start with NT error 1455.

cheers,
tonyi

Gary,

Also, if you have seperate physical disks in your NT box, establishing
multiple NT page files on each disk will increase your performance.

If you do have multiple NT page files on each disk, should they each be
greater than the size of shared memory Sybase is using? Or do the total
of their individual sizes have to be larger than the shared memory
Sybase is using?

Hi Bill,

The overall total is what matters.

That should have read:

  • "If you do have multiple NT page files, one on each disk, should they each be greater than the size of shared memory Sybase is using?  Or do the total of their individual sizes have to be larger than the shared memory Sybase is using?"
Does your answer still stand?

Thanks!,

Hi Bill,

Yes, the answer still stands. In fact I don't think you can have more
than one page file per disk anyway (at least not by normal means).

cheers,
