Hi,
Please let me know what are all the reasons in increase in the Memory utilisation of ux servers, and the solutions to face those issues caused by the memory utilisation (memeory Likage)?
Thanks in Advance!

Hi all,
This is my first post, so at the beginning I would like to be nice and say: "Hello all!" :)
I am looking for a C/C++ library for Linux CPU statistics. All I found is that it is possible to parse two files: /proc/cpuinfo and /proc/stat to gain some needed information, but I would like to... (1 Reply)
Hi All,
Does anyone know what the best commands in the UNIX command line are for obtaining this info:
current CPU usage
memory usage
virtual memory usage
preferably with date and time parameters too?
thanks

Hi,
We have an issue on our lpar where the pin memory usage slowly and regularly increases approx 1.5% a day until it reaches its 80% threshold
We have to regularly reboot the lpars to release the pin memory as we have found that killing all processes does not release it.
However,... (1 Reply)

Hello,
Looking for some help. I am trying to gather data at each server showing when the physical CPU is being used the most based on a weekly timeframe.
I know this data can be seen through NMON but with multiple servers in our environment it could take a real long time. is there a easier... (4 Replies)
Hi,
We have around 1000 server (Red Hat + Suse + Parallels + Solaris-9/10/11). Every month, we generate a report for all servers for CPU and Memory utilization in 'percentage used'. This report is generated from HP Openview and frequency is every file minutes. In HP OpenView, we are picking 20... (0 Replies)
I am facing issue related to performance of one customized application running on RHEL 5.9. The application stalls for some unknown reason that I need to track. For that I require some tool or shell scripts that can monitor the CPU usage statistics (what we get in TOP or in more detail by other... (6 Replies)

dbd::gofer::transport::stream
DBD::Gofer::Transport::stream(3) User Contributed Perl Documentation DBD::Gofer::Transport::stream(3)NAME
DBD::Gofer::Transport::stream - DBD::Gofer transport for stdio streaming
SYNOPSIS
DBI->connect('dbi:Gofer:transport=stream;url=ssh:username@host.example.com;dsn=dbi:...',...)
or, enable by setting the DBI_AUTOPROXY environment variable:
export DBI_AUTOPROXY='dbi:Gofer:transport=stream;url=ssh:username@host.example.com'
DESCRIPTION
Without the "url=" parameter it launches a subprocess as
perl -MDBI::Gofer::Transport::stream -e run_stdio_hex
and feeds requests into it and reads responses from it. But that's not very useful.
With a "url=ssh:username@host.example.com" parameter it uses ssh to launch the subprocess on a remote system. That's much more useful!
It gives you secure remote access to DBI databases on any system you can login to. Using ssh also gives you optional compression and many
other features (see the ssh manual for how to configure that and many other options via ~/.ssh/config file).
The actual command invoked is something like:
ssh -xq ssh:username@host.example.com bash -c $setup $run
where $run is the command shown above, and $command is
. .bash_profile 2>/dev/null || . .bash_login 2>/dev/null || . .profile 2>/dev/null; exec "$@"
which is trying (in a limited and fairly unportable way) to setup the environment (PATH, PERL5LIB etc) as it would be if you had logged in
to that system.
The ""perl"" used in the command will default to the value of $^X when not using ssh. On most systems that's the full path to the perl
that's currently executing.
PERSISTENCE
Currently gofer stream connections persist (remain connected) after all database handles have been disconnected. This makes later
connections in the same process very fast.
Currently up to 5 different gofer stream connections (based on url) can persist. If more than 5 are in the cache when a new connection is
made then the cache is cleared before adding the new connection. Simple but effective.
TO DO
Document go_perl attribute
Automatically reconnect (within reason) if there's a transport error.
Decide on default for persistent connection - on or off? limits? ttl?
