Thanks for your answer. I like your analogy but I thought that in my case dealing with a big Database server (5 TB data warehouse database ) having extra Async I/O processes would increase/help performance. What worries me is I'm executing the isotat -AQ command and I'm getting :
I thought that this could be sign that there is a bottleneck in this case. Maybe there isn't because I'm not a Unix expert.
Hello,
I have a performance problem on an AIX box. I'm not sure what is causing this and hoping someone may have suggestions. Currently I'm noticing that cpu's are waiting while the box is in a idle state. I checked the disks and none of them are at 100%. If they were then I would understand... (3 Replies)

I'm doing performance testing for one application which works on AIX.
But I don't know which performance parameters of memory need to be collected. Now, I just know very few:
1. page in
2. page out
3. fre
They are all collected by "vmstat" command.
I want to know, except for above... (2 Replies)
I am trying to analyze the performance of an AIX system. I think I may have a disk I/O issue, but I am asking for help to validate or invalidate this assumption. I ran the commands below during a period of peak load.

Hello
I am new user of AIX; I have only basic knowledge of the UNIX commands, and I want to create script that will monitor the performance and resources usage on AIX 6.1 machine.

Hello,
I encounter some performance issues on my AIX 5.3 server running in a LPAR on a P520. How do I investigate performance issues in AIX. Is there any kind of procedure that takes me to the steps to investigate my server and find the sub systems that is causing the issues?
The performance... (1 Reply)
Hi,
I'm supposed to capture many performance stats on AIX 6 and stuck up with below:
Priority queue
Disk cache hit%
Page out rate
Swap out rate
Memory queue
I see vmstatis helpful for "page out" but not sure how to get the "rate".
Could anyone please let me know how to get these... (4 Replies)

MRINFO(8) System Manager's Manual MRINFO(8)NAME
mrinfo - Displays configuration info from a multicast router
SYNOPSIS
/usr/sbin/mrinfo [ -d debug_level ] [ -r retry_count ] [ -t timeout_count ] multicast_router
DESCRIPTION
mrinfo attempts to display the configuration information from the multicast router multicast_router.
mrinfo uses the ASK_NEIGHBORS IGMP message to the specified multicast router. If this multicast router responds, the version number and a
list of their neighboring multicast router addresses is part of that response. If the responding router has a recent multicast version num-
ber, then mrinfo requests additional information such as metrics, thresholds, and flags from the multicast router. Once the specified mul-
ticast router responds, the configuration is displayed to the standard output.
INVOCATION
"-d" option sets the debug level. When the debug level is greater than the default value of 0, addition debugging messages are printed.
Regardless of the debug level, an error condition, will always write an error message and will cause mrinfo to terminate. Non-zero debug
levels have the following effects:
level 1
packet warnings are printed to stderr.
level 2
all level 1 messages plus notifications down networks are printed to stderr.
level 3
all level 2 messages plus notifications of all packet timeouts are printed to stderr.
"-r retry_count" sets the neighbor query retry limit. Default is 3 retry.
"-t timeout_count" sets the number of seconds to wait for a neighbor query reply. Default timeout is 4 seconds.
SAMPLE OUTPUT
mrinfo mbone.phony.dom.net
127.148.176.10 (mbone.phony.dom.net) [version 3.3]:
127.148.176.10 - 0.0.0.0 (?) [1/1/querier]
127.148.176.10 - 127.0.8.4 (mbone2.phony.dom.net) [1/45/tunnel]
127.148.176.10 - 105.1.41.9 (momoney.com) [1/32/tunnel/down]
127.148.176.10 - 143.192.152.119 (mbone.dipu.edu) [1/32/tunnel]
For each neighbor of the queried multicast router, the IP of the queried router is displayed, followed by the IP and name of the neighbor.
In square brackets the metric (cost of connection), the threshold (multicast ttl) is displayed. If the queried multicast router has a newer
version number, the type (tunnel, srcrt) and status (disabled, down) of the connection is displayed.
IMPORTANT NOTE
mrinfo must be run as root.
