Hi, Dear all:
I am working on creating a cluster simulation with 500 nodes. Each node is
supposed to have its's own database.
I am curiously about following questions:
1. Is it possible to create 500 sqlite databases on one server machine, on
which the simulation is running. Each sqlite is supposed

Yes. SQLite database is just a file. You can have as man
Hi, Igor:
Thanks for reply!
Yes, I just noticed the sqlite data file is nothing but a empty file.
Thanks!
About the remote visit, if the sqlite data file is created on a NFS, will
the remote visiting process be considered as a equal local process?

I'm using multiple connections to sqlite database from more threads in my
application. Few customers reports sqlite error in windows vista which I cannot
get in my system.
Error code is 0xA0A (I haven't turned on extended error codes). This error
number gives no sense to me because it is not de
ye,
at the fifth question of the SQLite FAQ, at
http://www.sqlite.org/faq.html, it is explained why using a sqlite file
by multiple nodes over a network with a NFS filesystem is not a good
idea. I would avoid it although the FAQ does not say 'it does not work',
it only says 'it might not work'

Are you using the native api or one of the wrappers?

Hi,
I just merged our code base with the sqlite 3.6.2 distribution and
decided to run the tests on Mac OS X (10.5.4). I had two issues:
(1) make tests would not properly link the testfixture - it complains
about missing Tcl symbols - I guess the libtool link phase does not

Sorry for the newbie question, but how is the regression testing
invoked?
I tried "make check" with the 3.6.2 "amalgamation" distribution in Unix,
but that seemed to do nothing.
Thanks,

When putting together fts, we never quite could come up with a really
solid way to handle snippets. A big factor was that fts is embedded
w/in SQLite, not directly w/in your program, so it's sometimes
challenging to provide a really wide API.
This is why there is both a snippet() function and an

Hi everyone,
I'm a BioConductor developer and we use SQLite (via RSQLite package) to
handle annotation of high-density oligonucleotide microarrays.
Our solution, implemented in the pdInfoBuilder package, worked great until
we got machines with quad-core processors. One particular setup is a machi

This might be a wild goose chase, and I'm not convinced it's directly
related, but AMD multi-core CPUs are known to have timing issues. Google
for "AMD negative ping" and you'll see it affects the results from the ping
utility for example. They've released a "Dual-Core Optimizer" patch to
correct
I would suggest you force your software to use only one processor on both
dual- and quad-core machines and check the timings again. If the timings are
in the range of expectancy (due to hardware speed/processor frequency) then
your software has a bug related to NUMA. The non-uniform memory architec

Chrome is built heavily on Gears... all SQLite all the way.
On another note, one of the reasons why Chrome may not yet be
available on Macs, in spite of using WebKit as its rendering engine,
is that Gears is not yet available on Macs via Safari (Gears can be
used on Macs via FF). So, this implies
