If you want the Oracle features like Triggers/Stored Procedures,
Integrity/Foreign Key Constraints, Transactions, Outer Joins, JDBC/ODBC
Drivers, C/C++ Pre-Processor for Embedded SQL, Perl and Python Access and
many more for the price of PostqreSql (i.e. FREE) look no further than SAP
DB.
SAP recently released its RDBMS in open source.
Check http://www.sap.com/solutions/technology/sapdb/
Here is an extract of SAP site
SAP DB is an open, SQL-based, relational database management system that
provides high availability and performance scaling from small to very large
implementations.
In addition, SAP DB goes beyond relational database technology by offering
object orientation as well as support for managing unstructured data. It
supports open standards including SQL, JDBC and ODBC; access from Perl and
Python; and HTTP-based services with HTML or XML content.
SAP DB is platform independent, so users can deploy it for a wide array of
projects.
Since 1994, the SAP e-Business Solution is available on SAP DB technology.
Today SAP DB is being used by nearly 800 customers.
You may also want to go directly to the FAQ page
http://www.sap.com/solutions/technology/sapdb/
I have no interest in the SAP company but when such a major company decides
to release such a great piece of software in open source, I believe the
Linux community should support them.
Xavier Neys.
PS: 800 SAP customers mean thousands of users :-)
PPS: I am a newbie to Linux but have years of experience with Oracle/Unix. I
still need to get my linux box up and running, than test this SAP DB and
compare it with Oracle. This explains why I posted this with Outlook. Please
forgive me :-)

Are you using a "winmodem"? Certain kinds of modems lack a built in UART
chip. The analog wave conversion ADC and UART functions are handed over to
the drivers for the modem. Unfortunately this forces the CPU to perform
this conversion so that you can send and receive data over the modem. Mpeg
video is a *very* CPU intensive operation. It's possible that the MPEG
decompression burns up so much CPU time that there's precious little CPU
left over to decode the modem signals so modem communications slow way down.
This used to happen to me. If you can confirm you are in fact running a
winmodem, well you'll really need to upgrade your modem to fix this issue.

Here's a more generic solution to your problem. This script can assign any
pid to a variable. It works by looking for the first pid by the name
specified and then storing that pid in a local variable.
#!/bin/sh
PROCNAME="xchat"
PID=`ps -ef | grep -i $PROCNAME | grep -v grep | awk {'print $2'} | head -1`
echo "The pid for $PROCNAME is $PID"
You'll probably have to tweak this to your specific needs but the idea
behind the script should be evident. If it fails on your system, break down
the pipeline into smaller chunks and verify each piece operates as expected.

You could always ASK the user...

I don't understand why the password is needed in the first place.

Isn't it also possibly not a disk SPACE problem, but a limited INODE
problem?
var is one of the filesystems that does tend to store LOTS of small files,
so it seems likely that he may be running out of inodes rather than disk
space itself...

As you say:
``it works by looking for the _first_ pid by the name specified...''
The only problem is if you have multiple instances of the same
program, then it won't work.
And instead of stringing all those commands together, you could use
the admittedly little known ``pidof''. E.g.:
$ pidof xchat
12033
Same caveat as before, it will not work properly if you have multiple
instances of the same program.

passwd 0.64.1, which works with Linux-PAM, does. Also, I noticed you
conveniently forgot to include the end of the message, referring the
poster to chpasswd and chsh, which also could be used to solve his problem.
How quaint.
I added my original reply to the end of this message. Have a nice day.

Subject: modelines for SVGA/Voodoo3 ?
Date: Sat, 25 Nov 2000 09:25:49 -0500
Greetings:
I have a Voodoo3 installed and it works beautifully under XFree86
4.01. However, my SVGA apps are all screwed up, mainly because I haven't
set modelines in the libvga config file. Since there are no modelines in
the current XF86Config, how do I find the correct settings for
libvga.config ? I seem to recall a utility for this purpose but I've not
found anything yet. TIA !

Hi all
I hope someone can help me with this.
I have a process running on a terminal. Is there any way to transfer that
process to a different terminal without interupting its processing?
I know I can do this using screen, but I forgot to start screen before I started the
program running.
Thanks in advance for any help.

This is not a problem for *Linux*. If you were booting from these disks
and they were large enough to have more than 1024 cylinders, LILO would
be unhappy (unless they were partitioned to have a /boot or / partition
whole under the 1024 cylinder limit). MS-DOS would be unhappy if the
disks were large. Since none of this applies, this is no big deal.
"MN> 2) Does the "unable to allocate IRQ for adaptec controller" refer to the
"MN> second controller that I am not able to access? (which is shown above as
"MN> using the same IRQ as the first one - IRQ 11). But, the EISA setup program
"MN> does not give IRQ choices for 'Enhanced Mode'...
"MN>
"MN> As a note, these were working in the same box while running the SCO
"MN> Openserver O/S. However, I had these cards set to 'Standard Mode' (instead
"MN> of 'Enhanced' - I read that Linux supports the AHA1740 in Enhanced Mode).
"MN> Therefore, on the SCO setup I had the IRQs set to 9 and 10, the I/O Port set

It appears that Linux will support ONE AHA1740 in Enhanced Mode, but
not two... You should either set one (or both) cards to 'Standard Mode'
and use different IRQ's for the two cards...
