Correct, it is for test server, not the production server which has the performance issue. The test and the production are setup the same.
I wanted to show the people how to utilize iostat to identify the I/O with the mount points.
But I do not have the root access on production.
I am no Solaris expert by any stretch, but some principles in performance tuning remain the same in every OS: does the production server have "real" disks or is it a virtual guest operating on virtual disks too? If the latter is the case it is probably the wrong place you are looking at anyway. Under the virtual disks there have to be some real devices - the LUNs on a storage box, members of a RAID in the host server, whatever. It is at these systems where you have to measure I/O, not on your virtualised guest.
Consider this (hypothetical) scenario: a server with 5 guests, g1-5 and a disk in this server where virtual disks for these guests reside. If g5 has heavy I/O this will influence the remaining available bandwidth which g1-4 could use. Therefore measurements on g1 because this guest has "intermittent performance issues" will tell you nothing about real issues, it will in fact only tell you when g5 has load peaks. You may not even know what you measure because maybe you don't know what g5 is doing and when.
It is a worthwhile effort to first get a detailed setup so that you can visualise the "flow" between the various interdependent parts of the machinery. Only then test/measure one component after the other to find out where the bottleneck is located.

Hi All
I Know it is a really basic and stupid question perhaps...But I am going bonkers..
I have following valid paths in my unix system:
1. /opt/cdedev/informatica/InfSrv/app/bin
2. /vikas/cdedev/app
Both refer to the same physical location. So if I created one file 'test' in first... (3 Replies)
Hello all,
I'm sharing 1 volume from a Sun Storage array (6130), out to 2 servers. Created a slice on one server and mounted a filesystem. On the other server the disk already sees the created slice from the other server (shared throught the storage array, so mounted this filesystem as well.

Hello, I have an AIX Oracle database server that I need to create a new filesystem/mount where I can create a new ORacle home to install 11g on. What are the needed steps to create this? There are mounts for Oracle 9i and 10g already. Thank you.

Dear Gurus,
Could it be possible to have the output of df -k sorted? The df -k output messed up after recent power trip.
Also, is there any folders that I should look into to reduce the root size (other than /var/adm and /var/crash) after server crash?
Many thanks in advance.
