I downloaded, compiled, and installed the latest MySQL release from the source code at www.mysql.com last night. I was running through the tests documented in the INSTALL-SOURCE file, and I've found that mysqladmin -u root shutdown does not work.

RE: Query Not Using Indexing
Adam Douglas writes: Ahh what do you mean all tables are not related with common columns? They are not suppose to be related with a common columns. PostalCodeInfo and Company table are completely two different things. Yes that is correct, I've resolved the issue with PostalCodeInfo for indexing in the query. I had column types not matching the same through my tables. But I'm still lost as to why I can not get CompanyShipInfo to use indexing in the query. That's find but shouldn't I still be able to go down even further as to how many rows are analyzed? CompanyShipInfo has 235 rows and all are being read by the query. Here's the new explain of the query below. Another thing that happens is when I tried to ALTER PostalCodeInfo and PostalCodeReps table schemas MySQL seemed to be hung and put the CPU usage at 99.0% to 99.02% (never ending it seems). Both those tables only have 42657 rows each. Any ideas why these two tables seem to hang when anything major is done on them? Funny thing is it seems to be random when you execute a query that uses these two tables. Is there something I'm missing for MySQL configuration or bad table design? I'll post the table schema's below the explain query. MySQL is truly doing it's best in your case. If of 6 tables you have a broken chain of relations, you will have a Cartesian product. Regarding ALTER TABLE, that is also expected behaviour, as MySQL is re-building indices and has to use lot's of CPU. -- Regards, __ ___ ___ __ / |/ /_ __/ __/ __ \/ /Mr. Sinisa Milivojevic [EMAIL PROTECTED] / /|_/ / // /\ \/ /_/ / /__ MySQL AB, FullTime Developer /_/ /_/\_, /___/\___\_\___/ Larnaca, Cyprus ___/ www.mysql.com - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

There are 2x256 MB and 2x128MB sticks in there, all at a spped of 133. Please don't ask me what kind of motherboard we're running in there, but that shouldn't be a problem. Couple months ago I had 256 MBytes in my Slackware Athlon workstation labeled 100MHz-128MBytes on both chips. Turns out one of the chips was 133MHz and the other was 100MHz (Fry's electronics labeling dep't). Sadly, the bucks I spent on a new PIII true Intel Board qualified the chips and I put the 2 133MHz chips into the Athlon and the 2 qualified P100Mhz chips into the PIII Intel board. Honestly, my Athlon was crashing on Slackware and the Intel was crashing on Advanced Server regularly. Slackware with 2.4.1 kernel sometimes twice; sometimes 3 times in a day; sometimes would go for a few days; The Advanced Server couldn't stay up long enough to show a login without a BSOD, except randomly sometimes. Switched the chips after verifying them, and now the Athlon can run 3 weeks at a time vanboers@sedona:~$ w 4:06am up 22 days, 13:27, 0 users, load average: 1.10, 1.24, 1.14 USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT (developer machine, what can I say? 1+ Load Avg due to SetiAtHome, BTW) and I've seen the Advanced server run close to a month (between virus patches and IIS security updates). On average, the developer Athlon machine still beats the Advanced Server machine on uptime, but the point is that the memory was killing both of them. Don't take the label for granted. I can't tell you how much time I wasted determining this. I can tell you I lost over $5k US in billing, though because I assumed the label was correct. I lost the time because I assumed I was doing something wrong and couldn't bill my client for development during the month it took me to find out what the problem was; disparate memory on the same motherboard. If the labeling had been correct; I would have just swapped the chips. Hope that makes sense. Updatedb is running around midnight, but I just found out that cron.hourly could be a problem in there as we experienced another crash tonight which was at 1:59, the crash yesterday occured at 4:59. Always around the full hour. I've tried and disabled cron.hourly for now, hoping it will help. Seems like it wasn't a problem of mysql, it was just mysql which was killed and thus appeared in the kerne ltrace or something. You're probably onto something here. Great forensics work! I have experience with the cron.hourly/cron.daily/etc. processes that fire up when you have the logrotate packages installed. It's been a while, but while I was using RedHat at Intel I convinced them these crons and the logrotate packages should either be audited thoroughly, or pitched because of the second-guessing they do to the admin of the machine/network. Intel opted to replace logrotate with an implementation (msgarch) I've had running on all of my production machines for several years on some of their monitoring servers in the division in which I was working. (Intel applied my implementation on modified Red Hat and Slackware monitoring servers at that time. I have no idea what they've done with their Red Hat implementations and don't know if they currently deploy Slackware servers at this point in that division). I haven't been at Intel for over 4 months, so I have no idea what they're up to with their server software in that division, at this point. If logrotate is the cause, I'll send you msgarch and the cron entries for msgarch. Sorry I didn't OSS msgarch before, but I hadn't heard of many complaints on logrotate. The BSD people use it also and most with a certain level of satisfaction. msgarch is my own recipe, but has been implemented by many of my affiliates for many years. I just didn't OSS it because most people have been using LogRotate and I thought it redundant to toss msgarch to the community. If that assumption was wrong, let me know. I'll pitch msgarch into the community. Seems your machine might have a wrong hardware component somewhere. I'd check it out if it's a production machine. We sure will, but the system is located about 500 kilometers from where our bureau is, so I hope it will stay alive at least over the weekend :-) This is a problematic situation.

I hate to say this, but my most important machine is 2000 miles away from me, but I tested it locally for 2 months on the hardware I put it on before I deployed it. That might be the lesson, here.

Re: New member question
there are a number of ways you could accomplish this. depending on how large the database is, you may want to try exporting it to csv (comma separated value) format, and then importing it into mysql, using either the load command, or a third-party utility like phpmyadmin (which is what i generally use for tasks like that). another way is if you are indeed using php and you have odbc support compiled in... you could simply read from the access database and simultaneously write it to a new mysql table. that's what i could think of offhand..someone else out there might have a better solution or three. =) ~shawn On Sat, 4 Aug 2001, RCA Webmaster wrote: I have just subscribed to this list, so forgive me if my question has been answered many times before but I was not sure where else to find this information.

There was nothing about this. So if this charset not called somehow different then it is not supported. But if this an true we are really interested about information, how Arabic language is organized. Maybe you can point to some source on the web? Changing left-right directions seems easy to me on first look. We need information: Is Arabic an single or multibyte character set? In which order these characters should appear? (prorably some national standard describes this) Also we need information about upper-lower conversion if it is applicable at all. And after all the smallest thing is translating about 220 error messages to Arabic.

Re: Thinking of switching from MyISAM to InnoDB
If you want a MyISAM table to grow larger than 4GB you have to do alter table tablename max_rows=1 or maybe its 'maxrows'... Once you do that, you will be able to stuff the table as full as the OS will let you. Innobase will allow you to get around this by making a bunch of smaller files to create a larger table space... but keep in mind the max size for a blob is 4GB.. (yah that is pretty damn huge tho heh). Im not sure what the max size for a MyISAM blob is. Hope this helps. ryan - Original Message - From: Nick Seidenman [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Saturday, August 04, 2001 9:54 AM Subject: Re: Thinking of switching from MyISAM to InnoDB On Saturday 04 August 2001 09:25, Sinisa Milivojevic wrote: Nick Seidenman writes: Apparentlly there's a 4 GB limit to a MyISAM file when the table it contains has VARCHAR, TEXT, or BLOB columns.
