Subject:MySQL, No problems !!
View as plain text  
Hi all,

I those times of trouble reporting, i have to pitch in.

I still have to say "Go Monty, Go" :)

I do not have any problems at all, running ->

On the server side:
	Linux (slackware 3.5) 
		Linux 2.0.34 #3 Mon Aug 29 23:31:01 CEST 1998 i586 unknown
		Apache 1.3.3 (php3)
		mysql  Ver 9.20 Distrib 3.22.4-beta, for pc-linux-gnu (i586)

	Linux (slackware 3.5) 
		Linux 2.0.35 #3 Mon Aug 31 23:42:33 CEST 1998 i586 unknown
		Apache 1.3.3 (php3)
		mysql  Ver 9.20 Distrib 3.22.4-beta, for pc-linux-gnu (i586)

	Linux (slackware 3.5) 
		Linux 2.0.36 #3 Mon Aug 28 22:30:10 CEST 1998 i586 unknown
		Apache 1.3.4 (php3)
		mysql  Ver 9.20 Distrib 3.22.4-beta, for pc-linux-gnu (i586)

	(and some RH5.x/slackware 3.x, Kernel 2.0.x, Apache 1.3.0 (php2), DB client)

On the client side:

	Win 95/98: > 30 (unknown)
		MyODBC Ver 2.50.17

	Win NT 4.0 Server/WrkStation (SR 1->4) = 5
		MyODBC Ver 2.50.17

	Linux (slackware 3.5)  > 10 (unknown)
		Linux 2.0.33 #5 Mon Aug 31 23:00:48 MET DST 1998 i586
		mysql  Ver 9.20 Distrib 3.22.4-beta, for pc-linux-gnu (i586)

This setup is supplying detailed info on a point-to-point basis on any traffic
involving any front-line router/gateway (i'm involved in) for the last 3 months,
and consolidated for the last 2 years. I know this is basic stuff, but it's
still faster, and more "install and go" than the two heavy db (oracle and sybase)
test servers i have running. At some point i'll do a comparison on these date,
oracle/sybase against MySQL. Not that i have any cracks in my beliefs.

This MySQL environment is running "close to" uninterrupted 23 hours a day.
But at midnight, all routers and servers has to report (in a cron job), al 
traffic occurred today (last 24 hours) on a source destination ip-addr basis, 
consolidating, (if anybody feels like commenting, feel free) this is far
more than 1 million records a day, collected like this:
