High memory utilizations

Hi All,

Advise needed, we have a HPUX server with the following services and specifications:

OS: HPUX B.11.31
SAP ECC 6.0
Oracle 10g

CPU info:
1 Intel(R) Itanium 2 9100 series processor (1.67 GHz, 18 MB)
666 MT/s bus, CPU version A1
2 logical processors (2 per socket)

Memory: 16362 MB (15.98 GB)

Platform info:
Model: "ia64 hp server rx2660"

OS info:
Release: HP-UX B.11.31
Version: U (unlimited-user license)
Machine: ia64
vmunix _release_version:
@(#) $Revision: vmunix: B.11.31_LR FLAVOR=perf

Problem is sap application even on sleep mode still hold the RAM and memory utilization reach 100%. Even if there is no user activity utilization is still high. Can this problem be fix with certain kernel parameter tuning? Please advise.

Thanks in advance.

Hi,

I think you need to tune SAP and Oracle first, and then go for system parameter tuning.

What do you mean by sleep mode?
Using 100% is what the kernel tries to do.

There is nothing to fix. What problems do you have? What does "swapinfo -tam" show?

As Suraj said, what do values to you have for filecache_max(5) and filecache_min(5)?
