Kernel sizing for BeaTuxedo/PeopleSoft/Oracle

Kernel sizing for BeaTuxedo/PeopleSoft/Oracle

I am looking for a document that supposedly exists from either HP, PeopleSoft, or BEA that will assist in calculating Unix kernel parameter sizes based on the number of oracle databases, the number of BEA Tuxedo Application Servers, as well as the size of the HP hardware.

We are running HPUX 11, Oracle 8.0.6, PeopleSoft 7.5, Tuxedo 6.5 (multiple instances & multiple App Servers) and are experiencing some performance issues. We would like to recalculate these numbers but due to personnel changes cannot find the document.

Any help in this area would be most appreciated.

The oracle docs website is

You can get oracle manuals related to HP-UX over there.

You should examine if you systems are hardware/disk bound before aiming to tune the kernel. Reconfiguration of hardware, particularly through intelligent lvm primary and alternate path selection will get more out of your system than kernel modifications.

You should analyse data access paths to your disks, your disk partitioning and your disks themselves..

Of course if glance/measureware or perfview suggest you are bound on let's say cpu, then you should consider adding another proc..

Kernel tuning templates and perf guidelines can be found at at and from the release notes of most serious db vendors, for example was mentioned above.

Good luck,
It works for me (tm)
