Re: Start MySQL with --intit-file?
Hi,
try putting the full path to the init file, and also try putting
the update command after the two grant commands (if you put it first
and the user r...@173.8.172.53 didn't already exist then the password
will not be set for that user) and put a flush privileges as the last
line ,
thanks Andy.
Quoting Jason Todd Slack-Moehrle mailingli...@mailnewsrss.com:
Hi,
I am trying:
[r...@server1 ~]# /etc/init.d/mysqld restart --init-file=cloudsql.sql
Stopping MySQL:[ OK ]
Starting MySQL:[ OK ]
the cloudsql.sql file contains:
UPDATE mysql.user SET Password=PASSWORD('xxx') WHERE User='root';
FLUSH PRIVILEGES;
GRANT ALL ON mysql.* TO 'root'@'localhost';
FLUSH PRIVILEGES;
GRANT ALL ON mysql.* TO 'root'@'173.8.172.53';
commit;
But I still get that I cannot connect from 173.8.172.53
I still dont see what I am doing wrong...

Re: Mysql on Ultrasparc T2 and floating point performance
Hi Dan, Yes, actually, I already know that parallel performance will be much improved, however, I was expecting more improvement on single threads as well, since the specs say that it takes 40 clock cycles just to access the FPU on the T1, but something like 6 clock cycles on the T2. So just from that perspective it seems like there should be a significant improvement for single threads, not just parallel performance. At least that's the way I read the docs from Sun on this. At any rate, my expectations here are clearly wrong, and I guess I'd just like a better understanding of why I'm getting it wrong. Hi Rod, I wouldn't expect any noticable difference running a single query that is taking anthing than less than a second if the only technical difference is that it takes 34 less clock cylces to access the FPU, thats 34 clock cycles on a cpu with 1GHz clock. The additional FPUs and reduced clock cycles to access the FPUs simply improve preformance when running mutliple threads that require FPU calculations, ie almost no overhead up to 8 simultaneous FPU calculations and less overhead when the number of simultaneous calculations goes over the number of physical FPUs due to the reduced clock cycles to access a FPU. In general my understanding of the T1 vs T2 architectures is that the CPU and FPU cores are essentially the same regarding preformance per thread but with additional threads per core and additional FPUs and some other nice bits like on board Gig Ethernet and support for 2 socket servers, plus any bump in the clock speed over the older boxes obviously. thanks Andy. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql?unsub=arch...@jab.org
Re: Sun bought by Oracle
Only time will tell what will happen, but I have read a few articles saying Oracle had been interested specifically in buying MySQL from Sun as it gives them an open source DB offering (which they dont have now right?), and that brings with it contact with potential customers for support or non-free solutions etc... However that was from the internet press so its all just rumours and supositions ;) cheers Andy.

Re: MySQL runs on 16-cores server
Hi, In what way can having more cores slow down MySQL (or any other app for that matter)? Are you simlpy referring to the fact that some mutlicore servers might be slower in single threaded preformance than a higher clocked single core system? If I have a mutlicore system with fast single threaded performance I wouldnt expect it to be slower in almost any cases with something like a mutliprocess database system, thanks Andy. Quoting mos mo...@fastmail.fm: Using more cores with MySQL doesn't mean it will run faster. In fact, it could slow it down. Make sure you have done benchmarking with your current computer so you can compare the difference.

Re: Replica questions
:S Hi Bryan Actually changing the slave setup after a reboot is a very bad idea, you will have inconsistent data on your slave because every transaction made from when you rebooted the server to when you reset the position will not be copied from the master. Thats the point of the position information, that MySQL can know what data has been replicated and what data has not been. My understanding is that you should never have to reset the binlog position info after initial setup unless you are reinitialising your slave with a new copy of the data from the master because the slave broke for whatever reason. I have several DBs copied to slaves and have never had to reset anything following a reboot of the slave (or master for that matter). If you are finding replication stops after a reboot then I think you have a serious problem, but don't know what that might be. Post some more info and someone on the list can probably help, thanks Andy. Quoting Bryan Irvine sparcta...@gmail.com: The information is there and the replica can connect on a reboot but only if that information has not changed correct? e.g. I reboot the slave, and on the master just run reset master; the bin.01 could change to bin.02 and the pos change from 98 to 15443 or some such. If I do that do I then need to re-run the set master to statements when the slave comes back up? or can that be handled automatically? -Bryan -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql?unsub=arch...@jab.org

Re: Best RAID for a DB + LVM?
What RAID level to use, whether to use SCSI or SATA etc are all pretty much how long is a piece of string? questions. If you have a really high end hardware array RAID 5 may be faster than RAID1+0 is on a cheaper system. Basically RAID 5 = slower SATA = slower RAID 1+0 = faster SCSI = faster more physical disks = faster more expensive controller = faster ;) If you want to compare specific hardware you'll need to get your hands on it or find someone else who has already done a comparison. But it will make a huge difference to performance what disk array you have hooked up, just depends how much you want to spend Quoting Waynn Lue waynn...@gmail.com: I currently have a RAID 5 setup for our database server. Our space is running out, so I'm looking to increase the disk space. Since I'm doing that anyway, I decided to re-evaluate our current disk array. I was told that RAID 5 isn't a good choice for databases since it's slower to write. In addition, I've also been considering setting up LVM to take quick db snapshots, after reading various links on the web (and posts to this list). So on to the questions! First, if that's what I eventually want to do (get a new RAID server with LVM), do I need to do anything special to set up LVM on the new system? Second, what is a good RAID setup for databases? RAID 10? 0+1? Third, I have the choice of using SATA or SCSI in conjuction with the RAID drives I choose. How much of a difference is there in using SATA instead of SCSI, especially in light of whatever RAID I end up going with?

Re: Instance scale-out
Hi Claudio, I don't think its your English, I agree with you that its not just confusing it is wrong.

Re: Instance scale-out
Quoting John Daisley john.dais...@mypostoffice.co.uk: I would say in terms of the MySQL server the interface is either a TCP/IP Port, a Named Pipe, shared memory or a UNIX Socket. Depending on the host operating system it can use any of those interfaces but each instance must have its own interface. Just to chip in on this, an interface can obviosly mean a lot of things depending on the context and I accept the above discription in relation to MySQL. However in the text originally referenced the term used was network interface which I think most Sys/DB admins etc would understand to be a network interface in the sense the operating system considers it, ie a physical or virtual IP network intreface at the OS level. With regards the MySQL requirement the original text was discussing, I believe it is in reference to a TCP port which will normally be sitting on an OS level network interface hence I think this is badly worded in the text. thanks Andy.

frequent issues restoring mysqldump file
Hi, I'm not asking this as a specific question, more a general gripe looking for some kind of explanation. I don't do mysql restores very often, but many times when I have tried I get nasty errors as if its bombing out due to dodgy characters, or quote problems etc. Normally I am doing restores across the same major and minor revision (ie 5.1), but quite possibly with a point release difference. Its just quite frustrating, and also for such an old and widely used product surprising that a simple backup and restore doesnt work at least 99% of the time. So I suppose, Im asking is there anything people like me regularly do wrong that might cause this, or do other people experience similar issues and is there anything that can be done to improve matters? :S thanks for any help :) PS Im no MySQL expert but have used it a fair bit as well as Oracle and many Unixs and open source bits and pieces and Im usually quite good at making them do what I need ;) cheers Andy.

Can replication be compressed? Is it already in a binary format which could not be compressed further? If run through openssl would that serve to compress it too?

If on the other hand, your product is GPL itself, or you don't actually need to use any of MySQL AB's GPL'd stuff, then I fail to see what your problem actually is. - 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?

Re: working around lack of subselects

There really is no way to get around processing every record in table data. As that table grows, your query will get slower. But a 157K rows isn't really a whole lot. Thanks Brent. I know 157K rows isn't a lot, but you probably don't realise just how budget this hardware is. :) Anyway I'm pleased to say that I was pleasantly surprised at how fast the query completed even on this less than ideal server, it takes around a minute. As I only need to do it once a day and even once a week would be acceptable, there's plenty of room for growth there. Thanks for reassuring me there. :) - 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?

working around lack of subselects
Hi folks, I have a problem that normally I'd want to use subselects on. Here it goes: Table t1 has a column data_id. Table t2 has a column data_id. Both are foreign keys for the autoincrement primary column id of the table called data. I wish to delete every row from data which is NOT referenced in tables t1 and t2. The manual seems to suggest doing a three table left join and matching on both t1.data_id and t2.data_id being NULL. I am concerned this would take way too long, though I can get away with only doing this query say once a week. t1 currently has 221,422 rows, t2 has 18,726 rows, and data currently has 157,791 rows. Is this really the best way? I'm stuck with MyISAM table type and the hardware I'm doing this on is decidedly budget. Anyone got any recommendations? - 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?

Where have SRPMs gone?
Hi folks, Where have the links to MySQL SRPM packages gone from http://www.mysql.com/downloads/mysql-4.0.html ?? I found being able to build binary RPMs from your SRPMS to be useful, please could you make these files available again? (yes I am aware I could build them from a .spec file if that is still included on the .tar.gz, and this is what I'll do if I am told that you do not intend to provide these files any more). - 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?

Problems with upper/lowercase mappings
Hi folks. I have an application in which I require the only case equivalencies to be a-z A-Z. What I mean is, e/E should be regarded as identical in strings, but neither e/É (E-acute) nor é (e-acute)/É (E-acute) should be regarded as identical. When the application was first written I was completely ignorant of this issue and so did no special coding, and used plain VARCHAR columns. Now I find that eéÉ are all regarded as the same by MySQL, but not by the client app I have connected to it. I'm now trying to work out how to fix that. My first idea was to use the BINARY attribute on those columns. This would seem to make the likes of e/É (E-acute) not match, which is what I want. Of course this would also prevent e/E from being regarded as the same, so my plan was then to make sure that anytime a string was taken from the client I would use LOWER() on it. I was happy with that plan until I discovered: mysql select lower(É); ++ | lower(É) | ++ | é | ++ (if this isn't coming out in your email, E-acute comes out as e-acute when you use LOWER() on it). There is no way I can make my client app regard é and É to be identical, even if I want it to, even if it would seem logical to you that it should be so. This cannot be changed. So, I'm now at a loss as how to store and work with this in MySQL. I need to use some of those columns as keys, and for joining tables, too. Does anyone have any ideas how I can make this work?

Opposite of --skip-networking?
Hi, I've compiled mysql-4.0.2-alpha from source, and I cannot seem to get it to bind to an interface and allow TCP connections. When I do a SHOW VARIABLES I see skip_networking=ON yet I am not starting mysql with --skip-networking. To reverse this situation I tried putting: set-variable = skip_networking=OFF in my.cnf, but it told me it was an unknown variable. Anyone got any ideas? - 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?
