alter system disconnect session for shared server session
Understanding this command can help to kill shared server session,
e.g. alter system disconnect session ' 11, 14521' immediate;
However, this didn't seem to work in my production situation. The session was not gone until we stopped application end.
Any comments ?

re-create AIX /dev/null
The type of /dev/null was accidentally changed by command "rm /dev/null*"
Its type should be char device as shown below.
-rw-r--r-- 1 root system 619851909 May 15 14:23 null 2>&1
crw-rw-rw- 1 root system 2, 2 May 15 14:24 null
after "rm null*" , it became
-rw-r--r-- 1 root system 41 May 15 14:24 null
-rw-r--r-- 1 root system 190 May 15 14:24 null 2>&1
something like a normal file.
Googled but those solution doesn't work, as I failed to delete /dev/null "file" although there is no error message returned.
e.g.
So my solution is to reboot the server, and it works for me since this is a test server.
#ls -l null*

memory bandwith test
I had 2GB x4 memory in my desktop, however recently one of them failed to pass memtest. Left three 2GB memory can be used temporarily, so I am wondering what exactly DUAL channel memory make sense.
Below are number I tested with mbw .
About mbw
mbw(1) General Commands Manual mbw(1)
NAME
mbw - Memory BandWidth benchmark
SYNOPSIS
mbw [options] arraysize_in_MiB
DESCRIPTION
mbw determines available memory bandwidth by copying large arrays of data in memory.
The combinations
2GB+2GB DUAL CHANNEL
hmc@hmc-P55A-UD3:~$ mbw 1024
Long uses 8 bytes. Allocating 2*134217728 elements = 2147483648 bytes of memory.
Using 262144 bytes as blocks for memcpy block copy test.

Conclusion
Comparing the 2GB+2GB , DUAL channel and non-dual channel configurations, we can it is about 50% faster for using dual channel setup.
Below are number I tested with mbw .
