Intel Compiler
I am trying to use my binary Intel installation to compile PHP (which seems
to be doing a _very_ simple program). So in a statically linked
installation these references are defined in the embedded C library, but if
one is linking it with another application, it isn't.
Possibly the intel C library would need to be distributed with the binary
application for the sake of linking with other applications? Thoughts?
To quote the Intel C++ Compiler release notes:
The Intel C++ Compiler uses two routines _intel_fast_memcpy and
_intel_fast_memset to perform memcpy and memset operations that are not
macro expanded to __builtin_memcpy and __builtin_memset in the source code.
These are found in libirc. If you use the gcc compiler to link your
application or if you directly call the linker, ld, you might find these
unresolved symbols. For this reason, Intel recomends using the Intel C++
Compiler for linking, using the same compiler options used during the
compilation phase. However, if you see these as undefined externals, either
add -lirc to your link line, or change your includes so that memcpy and
memset will be macro expanded to the builtin forms and recompile. The Intel
C++ Compiler for IA-32 based applications calls a routine intel_proc_init
from the main routine of any program to ensure that the processor is
correctly set up. This routine is also found in libirc. These routines used
further entry points from glibc, so -lirc needs to be placed before -lc on
your command line.

Re: MySQL Web Clustering...
Unless you have a specific need for it, you could save yourself a lot of trouble by putting select tables or databases or even clients on each server. This also means you don't incur the added overhead of keeping the database in sync, creating actions if a master goes down, etc. Then just tell client1 to use database5 as their hostname for example. Replication requires that updates go to the master, which requires client-side code, or an intermediate daemon which analyzes the statement and forwards the request. -Mike From: Peter J Milanese [EMAIL PROTECTED] To: Roy Nasser [EMAIL PROTECTED] CC: [EMAIL PROTECTED] Subject: Re: MySQL Web Clustering... Date: Fri, 18 Jun 2004 11:25:45 -0400 I currently run LVS (pre-distribution) on my farm, which gets about 100M hits/month. Good points about LVS are that it is completely rock solid, and runs on minimal hardware. I have never run MySQL behind it, as I think that would be a bit flaky for a live site. Probably worth checking out though. I would think that instead of LVS Load Balancing, server failover might be a more viable path for MySQL. P Roy Nasser [EMAIL PROTECTED] 06/18/2004 01:58 PM To: [EMAIL PROTECTED] cc: Subject:MySQL Web Clustering... Hi All, We have recently acquired some new machines for our ASP service, and I am investigating different options and setups to optimize everything. We currently have one large DB server, with RAID5, etc, running mysql and a few smaller servers for web applications, and e-mail. These smaller servers arent all identical in their software, and they run different services. We currently have reached a certain limit in the DB as well as in some of our applications on the webservers, hence the need for something expandable. I have read slightly about MySQLCluster, as well as some other solutions such as openMosix, Mosix and LVS. I was wondering if you guys have experience, and what you would recommend for the DB and for the webservers. I still want to maintain them separate, even if I end up having 2 different clusters, I prefer to keep the DB away from the application for security reasons. Thanks!

Re: MySQL Web Clustering...
The meaning of that was client-side being sending inserts/updates to the master server. This would be done in the program/script upon an insert query. A daemon could forward insert/update requests to a master and all others round-robin and simply pass packets. This is if you have to make it seamless. Would require some work to make one though. -Mike From: Jeff Smelser [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: Re: MySQL Web Clustering...

Re: Safe Database Problem
Oh Jeeze- why didn't I think of removing this. When I upgraded the default is to have these two as 'Y', however, for some reason, that means that show databases shows all databases despite no permissions. That doesn't seem logical on one hand (if they don't have permissions to the database nor its tables, how could they create/lock on its tables), but on the other (they need to be able to see the databases to do a tmp table and a lock). In any case, problem fixed. I'm going to add a note to the docs to save people my troubles.

Re: Unique IDs
code it within your program. If this is in fact a primary key (whcih you seem to describe it as), then it should be distinct anyway. So do an INSERT IGNORE or even just an INSERT. It will fail upon duplicates. Check the affected rows or the insert_id (using whatever API you use to access MySQL), sleep for a second, then try the insert again. I doubt there's a good way to hang up the database on the issue. Cheers; -M From: Craig Jackson [EMAIL PROTECTED] Reply-To: [EMAIL PROTECTED] To: Keith C.

Since the web app is so large we don't want to change the method of assigning IDs as it would create a major project. I don't understand. If you're getting many users per second, and your timestamps have 1-second resolution, how could you possibly solve the problem without changing the method of assigning IDs? Are the many users per second periods just short bursts, and you're really only getting several hundred users per day? If so, I guess you could keep waiting a second and trying the insert again, but that could lead to indefinite delays if traffic gets high. I think you've got to bite the bullet and change the unique ID to something that's actually unique -- even an AUTO_INCREMENT would work. Thanks for the speedy reply and I have already recommended auto_increment for the solution. We do need that quick fix until the problem is fixed. How would I go about making Mysql wait one second between inserts. We only get about 1000 hits per day, but they tend to be concentrated in short time intervals. -- Keith C.

Re: Connect to MySQL via PHP
The _only_ real benefit of Apache2 over Apache1 is it's thread-based model. So why leave a stable, tried-and-true, robust Apache1 platform for no additional benefits at all? Why break compatibility? Why use the Apache2 branch if you don't need it? PHP itself works quite fine in a threaded mode. However, PHP uses an enormous number of libraries (GD, database libs, and many others) which may-or-may-not-be thread-safe. So these libraries can cause some serious problems... and when you're in a threaded model, programs doing funny things is not only difficult to track down, but also can cause serious issues with all of the other threads (due to shared process context on the system and shared memory). Lesson- just avoid it for the time being.

Also note, mdk has further separated the php.ini file to use separate php include files, similar to how they broke up apache's module configs... the structure is /etc/php.ini and /etc/php/#_phpmodulename.ini..they load in order of their number...
