Hi,
I am trying to send oracle archives over WAN and it is taking hell a lot of time. To reduce the time, I tried to gzip the files and send over to the other side. That seems to reduce the time. Does anybody have experienced this kind of problem and any possible ways to reduce the time.

At work, I'm in a Solaris environment working with csh, and $PATH is populated with anywhere between 10 and 20 entries.
Last week, every command I issued (even "ls") took several seconds, if not an entire minute, to run. Once I moved "/home/sybase/bin" to the end of $PATH, certain commands... (2 Replies)
hey guys,
We have two Sun x2100 servers running RHEL5 in a test environment. Both servers are fresh OS installs and hooked up to the same network switch.
When ssh'ing to one server, there is a significant delay, while ssh'ing to the other server, the connection is almost instant. We are... (2 Replies)
Hi All,
Please let me know the command to restart the network interface and enable it on boot in AIX, similar to /etc/init.d/network restart in Redhat.
Thanks,

Hi Guys,
I've inherited a mess of an infrastructure in my new job, there hasn't been a sys admin in post for about a year, so things are falling apart. The first thing to break after I started was the printer server. I have it working again, and people can print, however it's very slow, slower... (0 Replies)
I have identical M5000 machines that are needing to transfer very large amounts of data between them. These are fully loaded machines, and I've already checked IO, memory usage, etc... I get poor network performance even when the machines are idle or copying via loopback. The 10 GB NICs are... (7 Replies)
Hello everyone,
I've been a life long Unix/Linux user but I'll be the first to admit I have little specific AIX knowledge at this point and I've inherited these systems for better or worse so please forgive if I ask something in the wrong context. And yes, I've searched google for 3 days now :)... (3 Replies)

rhnsd
RHNSD(8) Red Hat, Inc. RHNSD(8)NAME
rhnsd - A program for querying the Spacewalk server for updates and information.
SYNOPSIS
rhn_check [options]
DESCRIPTION
rhnsd is a background daemon process that periodically polls the Spacewalk server to see if there are any queued actions available. If any
are queued, rhnsd will execute those actions.
rhnsd is typically started from the initialization (init) scripts in /etc/init.d/rhnsd. when it's time to poll the Spacewalk server for
available updates and actions. The default interval is every 240 minutes. The minimum polling interval is 60 minutes.
To check for updates, rhnsd runs an external program called rhn_check. This is a small application that actually makes the network connec-
tion to Spacewalk.
The rhnsd daemon does not listen on any network ports, nor does it ever talk to the network directly. Any network activity is done via the
rhn_check utility.
rhnsd can be configured by editing the /etc/sysconfig/rhn/rhnsd. configuration file. This is actually the configuration file the rhnsd
initialization script /etc/init.d/rhnsd. uses.
OPTIONS -i, --interval
Specify the interval that rhnsd should wait between checking the Spacewalk. Default is 240 minutes, the minimum is 60 minutes. This
can also be specified in /etc/sysconfig/rhn/rhnsd
-f, --foreground
force the rhnsd process to run in the foreground instead of automatically backgrounding itself, as it does by default.
FILES
/etc/sysconfig/rhn/rhnsd
Configuration settings for the rhnsd daemon's initialization script.
