With 50 clients, I assume you are trying to set up for a business.
If you do not know the answers to your questions, then you would really
benefit by hiring someone that does. This does not have to be a
consultant or employee...it could be going to a Linux system
vendor/supporter (like Penguin or VA Systems) or an OS provider with
heavy duty service packages (like RH) that can hold your hand a lot as
you get started. In the long run, you should save more $$ than you
spend by doing this.

Date: Fri, 21 Jul 2000 07:19:56 -0500
I'll give you a synopsis... but thats all..
Reporting software is just that.... it generates reports for or about
something. They come in two flavors. Software that reports on the status of
something, such as a report generator that reports and graphs the activity
on a web server, and 2: software that a human will use to generate a report
based on some other external data and entries of said data.
Relational database: Imagine two databases: 1: Fruits 2: Transportation.
Then ask yourself, "hay, a banana... that goes in a fruits table, and a
truck doesn't. But a truck goes in a Transportation table". So now that this
is established, a query table can be used to determine and construct a query
and where to "Relate" it to, to get the actual data from--ie, which table
actually contains the requested data.
Its really a glorified database with a little bit more functionality than
did ole' dBase... IMHO...

I think I agree here too... It sounds like he's got a goofy inode to file
count issue thats causing him to run out of space...
Usually the defaults work for almost anyone. When you deviate from those
defaults, then you have to sit down and manually figure out what is going on
the drive, and how much space you need for it, then calculate this against
an inode count. As much as I'd like it to be, it's never an exact science
either.
As an example, one of the drives on my server at home is reserved exclusivly
for MP3 files. These things typically kill 5Meg on average (for me anyway-I
use 256bit ordering in the convert). So I was able to come up with a count
that set my clustering at 2k for this volume and it's been pretty efficient.
The other thing I noticed is that he didn't reserve a separate partition for
/var or /tmp... I probably would recommend that so you don't risk trashing
the root or it's files.
Cheers;

Subject: Linux RamDisk - performance
Date: Fri, 21 Jul 2000 12:30:03 GMT
Hi,
I am running a set of numerical simulations on a RH6.1 Linux machine with
256MB of ram (soon to be upgraded to 1GB).
I create a lot of temporary files and r/w hard disk operations are
extensive. All these files are deleted after they are used and do not need
to be saved. At each timestep I create ~50MB of files.
Is there a way I could created a ramdrive and use it as a temporary (fast)
storage? I am looking for performance since the r/w operations do slow down
my simulation quite a bit!
Thanks!
Alberto

To get to the GUI from the console , either "startx" ( without quotes) or

In the same "Boot configuration" - "LILO" - "default boot configuration" -
change the selection to "Windows" or whatever it's called.

Some CD-ROM drives have "internal" volume control, which affects the output
to the sound card as well as autonomous headphone output.

Make sure you turn OFF, the APMD daemon as this might cause a problem.. I'd
boot it up in single user mode and watch it run for awhile... ("linux 1"
when you get the lilo prompt.) Or, make a bootable MSDOS disk and boot up
under this. Then, if the machine goes off, but the paripherie doesn't, then
you have either a bad power supply or a bad motherboard in the computer...
I don't believe you have an OS problem, I think you have the beginnings of a
hardware failure.
Not surprising either as GW's have been nice in that when they go bad...
THEY GO BAD. None of the middle of the road crap... Nice to fix.
My gut instinct is to do this and watch it. I bet you have a power supply
that is failing, and if it is, the PS's in them are rather generic enough
that you can shop around for a clone for it and probably get a heftier one
(>300w?)

You haven't stated what kind of tape-device you have. I'm assuming

Hi Matt
not really a problem, yet? I actually already use PHP3/Mysql for
personal use but was hoping to get an off the shelf package for a client
that could help them get there faster.
I am wary of getting a bespoke system built (upgrade, training, people,
etc. issues). My broad brush brief would look roughly as follows:
I need a system that.....
Supports content provided in key industry standards e.g. Adobe
Photoshop, MS Word, Adobe Illustrator.
Allows editing and refining of content prior to publishing
Manages content publishing cycle via workflow system
Allows published content to be tracked and managed
Supports content publishing to a variety of devices (e.g. Web, e-mail,
PDA, print, wireless)
Allows integration of external news feeds via open standards (e.g. XML)
Supports mirroring of content across multiple servers
Allows personalisation of relevant content on a user by user basis.
Separates content preparation from delivery
Supports pay per view delivery of selected content
Supports industry leading web servers
Provides ease of use features such as cookie based logins
Allows profiling of user interests based on past activity
Provide user reporting and tracking facilities
Support for metadata tagging of content
Offers personalisation based on articles being viewed ("view similar")
Provides for automatic detection of client browser and tailors content
presentation to fit.
not to much to ask, is it? ;)
does anyone have any knowledge or experience of systems - pros and cons?
thanks
