Tuning Suggestions: At the startup of the jvm the Xmx memory is pre-allocated. So by monitoring the usage of the jvm we can set the Xmx properly. Change the 2Gb Xmx settings to 1 Gb. When I was on the machine earlier there was no jvm taking more then 256Mb. This means we should be able to change all of them to 512Mb and be fine. As I mentioned before we only need to have large heap settings when we actually do a stress test but not for normal processing. Make these changes and bounce all the j…

AIX LVM Commands There are many ways to perform LVM functions in AIX. Logical Track Group When the LVM receives a request for an I/O, it breaks the I/O down into what is called logical track group (LTG) sizes before it passes the request down to the device driver of the underlying disks. The LTG is the maximum transfer size of an LV and is common to all the LVs in the VG. AIX 5L Version 5.2 accepted LTG values of 128 KB, 256 KB, 512 KB, and 1024 KB.

DNS How DNS works by default on AIX It takes AIX 75 seconds, by default, to attempt to use the secondary DNS server configured in resolv.conf for each DNS call. There are ways to configure this for a shorter time (see below). As of 9-10-2010, this has should be left default on all systems. Even 2 seconds can be an issue. This configuration is not really an issue as it is just how it works. If this happens, and there is an issue, a quick way to remedy this is to swap entries in the resolv.conf …

AIX Storage NOTE: For systems using PowerHA or PowerVM Live Partition Mobility, you need to set the reserve_lock to false for LUNs on each VIO. NOTE: For any LUN mapped to a VIO, you need to set the PVID to true. Then you can more easily map the LUN from the LPAR. This is best practice and needs to be done every time before creating the virtual disk.

AIX Virtualization - N Port ID Virtualization (NPIV) NPIV is an acronym for N Port ID Virtualization. N_Port ID Virtualization is a Fibre Channel (FC) industry standard technology that provides the capability to take a physical Fibre Channel Host Bus Adapter (HBA) port and assign it multiple unique world wide port names (WWPNs). The world wide port names can then be assigned to multiple initiators such as Operating Systems. Thus, NPIV allows physical N_Port to be logically partitioned into mult…

Channel bonding of LAN interfaces is implemented by the use of the bonding driver, which is installed in the kernel at boot time. With this driver installed, the networking software recognizes bonding definitions that are created in the /etc/sysconfig/network-scripts directory for each bond. For example, the file named ifcfg-bond0 defines bond0 as the master bonding unit,…

Troubleshooting & Resolving GFS issues In order for RHCS/GFS to function correctly the cluster must remain quorate. Once inquorate the cluster will halt all operations, which means all GFS operations are halted. The cluster manager does this in order to avoid data corruption (so its a good thing). The end goal of resolving RHCS/GFS issues is to get the cluster quorate.

SAN * Zoning * Soft zoning restricts only the fabric name service, to show only an allowed subset of devices. Therefore, when a server looks at the content of the fabric, it will only see the devices it is allowed to see. * Hard zoning restricts actual communication across a fabric. This requires efficient hardware implementation (frame filtering) in the fabric switches, but is much more secure.

SPEC Cheatsheet * SPECint_rate and SPECfp_rate are typically used to demonstrate the performance of multi‐processor systems. The results are given as base and peak, with the higher the result, the better the performance * This benchmark is limited to the chip and chipset, memory architecture, and associated compiler, so it does not cover I/O, operating systems, or other system components.

UNIX Tools for Windows These batch scripts roughly translate common UNIX and Linux commands into their Windows equivalent. Ultimately I created these scripts because I work primarily on UNIX systems and got tired of getting errors when I typed simple UNIX commands (cat, ifconfig, grep, etc) on my Windows machine.
