Of course I know AAA and have a basic idea of what RADIUS does and that why I asked this question b/c there are many ways to do what RADIUS can do.

So my question is why choosing it over the...

I guess I probably ask a dumb question but why use RADIUS for authentication as there are many ways to do it, as authentication is basically a user/password check?

What is the benifit(s) of using...

Thanks! :o

Hi all,

What is the simplest way to setting a variable to $1 if it exists ?
If I go with name=${"$1":-abc}, bash complains "bad substitution",

So I use
name="$1"
name=${name:-abc}

But...

Oh hey, thanks!

I paste the procedures here in case someone else also needs it. So in the cookbook chapter 2.4.3 , it mentions

Hi, thanks for answering my question!

I am a totally newbie to HACMP, so can you further elaborate how I can use Service Label for the NFS export ?

Thanks again!

Hi,

My NFS does not work till I start HACMP. The NFS service is indeed started when server starts. But it is not in active state, when I use lssrc to check NFS services' status I find they are all...

Thanks for replying my question.
I am using oracle. I know sql*loader probably works for this situation.
I just want to know whether awk has such kind of utility.

Hi all,

Is there anyway to make awk talk to DB ? So my awk script reads the data from some text file and eventually those data need to be stored in database.

So is there anyway to do it in awk...

Thanks for the answer.

Actually what I did not understand before was what was the value of running 2 instances of the same application on one node during the failover? If the resource group...

Thanks for the reply! Man, "possibilities are countless" but the learning curve is just :eek:

So another newie question. When failover happens, should I let the failed node auto-reboot or should I...

Thanks for the answerd and looks like I have got a lot of reading to do! Man :D

BTW my original question was "what is the benefit of running HACMP for an active-active cluster with the same app...

Thanks for answering my question!

But back to my original question, if concurrent HACMP RG means Oracle RAC and since no takeover is involved (and RAC10g has its own clusterware), what is the...

Hi all,

I am new to HACMP. So sorry for the newie question. But I did search the forum and it seems that no one asks this before.

So if a 2-node cluster runs in active-active mode (and the...

Thanks for replying although this was not what I was looking for.

I find from here Netcat: the TCP/IP swiss army (http://nc110.sourceforge.net/) saying that "Data from the network connection is...

Hi all,

When using netcat to transfer the data over socket, if no connection is established, how long will netcat keep the data; will it discard the "oldest" data ?

Say for example I use "Some...

Hi my server is power 550 with 4 core processors at 3.5 GHZ and 8G memory.

The app we develop is a Java application. So will this information help us to determine the sampling rate and peak time...

Thanks for the reply. And my system is indeed AIX (Power server). How did you know that ? COOL!!

I am not sure exactly why my customer want to monitor the cpu/memory usage. Maybe they want their...

Hi all,

When you monitor the CPU and memory usage, how often do you do it ? Do it too often or too rarely will both cause the problem. So does anyone have hand-on experience ?

And for my...

Thanks for the reply. With your input I further get the following information,



job control is by default turned off in non-interactive mode (shell script runs in non-interactive mode -- Bash...

Hi

Can someone explain in an easy way that why can't embed commands like fg or bg in a shell script ?

So if I put exec 3>&0 in my shell script (call it aname ) like this

#!/usr/bin/sh
exec 3>&0
awk 'BEGIN {printf "Enter your name:" ; getline name < "/dev/fd/3"}{ print name, $3 }' $1

And...

Thanks for you guys reply, it works!!:b:

Then the question remained is how to make "exec 3>&0" work in shell script (maybe I need to start another thread for it)?

Well, typing "exec 3>&0" at shell prompt works as you said. But if you put it in shell script, it just doesn't work (I hit this problem before and never figure out why). So the codes as you suggest...

/dev/fd/0 is the alias for /dev/stdin and no I don't mean to open several files in a row(of course the usage of cat in my example is just for demonstation). I just want to read the users' input and...
