Re: 'mysqladmin slave-st(art|op)' - is it implemented?
Hello again, Turns out it is implemented - but it's 'stop-slave' and 'start-slave'. Shoulda done a 'mysqladmin --help'. Grepping the source found it. - GW.

Hello, I see in the mysqladmin man page for version 3.23.55-1 that 'slave-start' and 'slave-stop' have at least been thought of at some stage (they're listed in the COMMAND SYNOPSIS section), but they don't seem to work when I try them... I've just been through the change logs for version 4, and can't find any mention of them in there... Can anyone tell me whether these options for mysqladmin are implemented? If not, can anyone tell me whether I can tell mysqld to stop or start replicating from a shell script rather than the mysql client?

Re: query cache
In the last episode (Jan 29), Rusch (ext) Reiner said: I've got one question which belongs to the new query cache in 4.01. I wonder why the cache should be deleted if there's a statement like update, insert etc. I think it must be considered that there are possible situations where this isn't the best way. For example: 1) select * from DATABASE where DATE = '2002-12-02' 2) update DATABASE set NAME = 'my name' where DATE = '2002-12-01' So 2) would kill the whole cache, but for 1) the update doesn't matter! Wouldn't it be better to look for what selects matters for the cache by updating something in the table??? For simple things like that, yes. But how do you determine what matters? Say you have these queries already cached: /* pretend your orignal record before your query 2) had name='fred' */ 3) SELECT count(*) FROM database WHERE name='bob' 4) SELECT count(*) FROM database WHERE name='fred' 5) SELECT date FROM database WHERE name like '%ame%' 6) SELECT * FROM database MONTH(date) = '12' 7) SELECT incomerange FROM database order by name You can keep the results of 3), but have to clear the rest. How do you distinguish between 1), 3), and the rest? The current cache is fast because it simply does a string comparison of the current query against all cached queries. Forcing it to keep record IDs or field ranges for each cached query would slow the lookup process to the point of uselessness. -- Dan Nelson [EMAIL PROTECTED] - 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?

I have to hand it to you for your documentation. You've probably done it enough to do it in your sleep by now :-) but it's still very helpful for potential helpers. Nothing in your procedure looks grossly wrong to me, but I also haven't installed any of these any time recently. There is one problem, though. You're missing the server name spec in your URL. Try file:///var/www/test1.php instead; note the two slashes, which are at the beginning of every URL, and the empty server name (the third slash right up against it). That, however, will only give you the contents of the file, since php is parsed by the server instead of the browser. The trick is that before you can get the test1.php file you'll have to make sure it's under your htdocs dir (see your httpd.conf; you didn't mention what you have for your DocumentRoot setting). Once you have test1.php in your DocumentRoot dir, try http://localhost/test1.php and see what you get. By that point you'll probably be in much better shape :-) At this point you're still struggling with getting apache configured and knowing how to talk to it; php and mysql aren't (or don't have to be) even involved. I don't have any particular pointers, but if you still have problems after these steps, start with the apache docs and try to get something simple like a static html page or an image to come up.

Re: Access XP crashes regularly when linked to MySQL via MyODBC
Loren McDonald wrote: Have you done all the office (or at least Access) XP updates? If not, it is possible that one of them my resolve your crash problem. I have been testing Access XP with the same versions of MyODBC and MySQL for a few weeks now and have yet to see a crash. About the only problem I have ran into is MySQL shutting down, for no apparent reason, every so often. I have just installed .55, so I'm waiting to see if it is still a problem. Can't speak for others, but... I've got the latest MDAC (2.7). I have tested with Access XP - bare, Service Pack 1 and Service Pack 2. I have also tried with a few startup switches, eg /safe which was recommended to me by M$ helpdesk. MyODBC options: - Don't Optimize Column Width - Return Matching Rows - Change BIGINT Columns to INT Drifting off topic... Also, not only does the developer version of Access crash, but the deployable, cut-down versions you can make with the packaging wizard also crash similarly. One stange thing I've noticed is that whereas sometimes Access will crash outright, other times it will simply prevent you from exiting the current record. If you try to either: - exit the form, or - move the focus to a sub / parent form, or - move to another record, Access will give an error dialog saying that the current action will halt any running code, even though there is no code running. Pressing either the 'End' or 'Debug' buttons results in the same dialog box re-appearing (in modal form). The only thing you can do at this point is to use the task manager to shut down Access. Also, (nearly finished) the deployable cut-down version, which isn't supposed to have any form / code editing abilities, also gives the 'End' / 'Debug' dialog. The above problem is another reason why I think the bug is in Access. -- Daniel Kasak IT Developer * NUS Consulting Group* Level 18, 168 Walker Street North Sydney, NSW, Australia 2060 T: (+61) 2 9922-7676 / F: (+61) 2 9922 7989 email: [EMAIL PROTECTED] website: www.nusconsulting.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?

Here's an example of how much data could be stored in a year: 1 value/minute are stored = 1440 values/day. 365 days / year. We have 100 different tables with 25 columns each. This makes 100*25*365*1440 = 1 314 000 000 values per year. A typical value could be 25,5624. How much space (in Mb) could this take up after a year do you think?

You can't control the order the records are modified. If your problem is that id is a primary key and it won't let you temporarily have duplicate id's, just drop the index, do your update, and recreate it. If you can't drop the index, you can sort of cheat by creating another unindexed column id1, then do three separate updates: SET id1=id, SET id=NULL, then finally SET id=id1. You might be able to do the first two at the same time with SET id1=id, id=NULL, but test it on a scratch table first :) Actually, you _can_ use ORDER BY with UPDATE. It works fine, if you do an update tb_roubr set id=id+1 where id1 order by id DESC on your table. DESC (=descending) means that UPDATE will iterate through the rows from the end (that is the highest number) to top (that is id=1). That way, you keep the primary key unique.

RE: mysqldump, exclude table?
Actually, you might want to play with sed or perl. mysqldump -u root --no-create-info -q --all-databases | sed s/'INSERT INTO acctlog'.*// is a first draft, although perhaps not optimal in speed. It will remove all acctlog inserts from all databases. You might want to play a bit with shell scripting if you need to remove acctlog inserts from only the 'server' database.

Changing user passwords
Hi
I have problem with passwords.
Normal users who have only 'USAGE' global privileges are
not able to change their own password. I tried to do fresh installation
of mysql 4.0.9 (and 4.0.8) on my windows workstation. I created new user
(as root):
GRANT USAGE ON *.* TO dummy@localhost;
then I logged in as 'dummy' (mysql -u dummy) and tried to change
password for dummy:
SET PASSWORD=PASSWORD('newpassword');
I got:
ERROR 1044: Access denied for user: '[EMAIL PROTECTED]' to database 'mysql'
This functionality worked just fine with mysql 3.23.54. and 3.23.55.
What kind of privileges normal user needs in order to change his/her own
password?

Replication Problems/Questions
Hi List I'm using 2 WinNT-Servers, Sp6 with mysql 4.0.5. max-nt. I ve setup a replication between these two servers as discribed in the manual and some small problems comes up. Maybe someone can give me some help. 1.) On the Master I create a user repl with the rights 'replication slave'. On the slave I used a user with all possible rights. Starting the replication with 'reset slave', 'change master to.' and 'start slave', I get an error: Show slave status says Slave_IO_running no and some entry in mysql.err. This Problem I could solve using a user in 'change master to ' that has also admin rights. What could cause the problem? 2.) The more important Problem: If the replication is running, and I try to replicate a table where data was inserted on the master with 'LOAD DATA INFILE...' or 'LOAD DATA LOCAL INFILE' the server process on the slaves crushes The files on the master, for LOAD DATA.were still there. Any Ideas? At Last one question: - could anyone explain me the meaning of the fields from show slave status ( I'm looking for a way to decide if the slave has replicated all the data from the master ) Best regards [EMAIL PROTECTED] - 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?

The Production server has MYSQL 3.23 and an older version of MYODBC then I have. No Crystal Reports installed. And the server is a faster machine then mine.

Re: Cardinality doesn't auto start
Grigor, Peter wrote: You need to run [analyze table] to create the index stats...do this reasonable often (once a day for a well-used table). This script will be run on servers around the world by regular people, not sys admins. I will have no control over their databases. Running [optimize table] on the table recreates index stats AND reorganizes/defrags/coalesces data pages...do this once a week or so. The one index I have in this database is on a field which contains TO_DAYS(NOW()). Therefore the return is automatically grouped in the database as each day is written in order. Is there any value in optomizing in this situation? Apparently, this index is working pretty well, as the time to execute the queries has halted at about 12 seconds on the test site and the time doesn't seem to change after optimizing. The rows in this database will not be edited. Deletion should always occur only from the beginning as deletion is be month or year and I can't imagine anyone not deleting the oldest months first. Will this operation cause fragmentation? I'm having a bit of trouble between the order in which I see the data onscreen and how the actual file is written. Look up the mysqlcheck utility--it lets you do this from scrips pretty easy. I see where I can write a script to run these functions, however, getting an end-user to run a script 'later' after the install, we all know is not an easy thing. I simply find it frustating that MySQL does not start its cardinality count automatically when an index is created at the time the table it created. It has been counting perfectly when I create the index after data is in the table. There also seems to be a 'isamchk -a' function which is supposed to jump start the cardinality count. I'm just hoping for a cure to getting this to start by doing something in the install script where there table is created as well as many other config files. Perhaps if cardinality were set to 0 it would begin the count on its own? I can find very little information regarding cardinality and have no idea about how one would set it to 0 if that did work.

Re: Storage issue
* Jonas Askås I'm wondering how well MySQL compress data. I'm about to design a database which will hold mainly _a lot_ of FLOAT-values, and since I do not really know how well MySQL compress data or how I could calculate this I'd really appriciate a little guidance. mysql does not compress data by default, but you can use a tool to make a compressed read only table, see the manual: URL: http://www.mysql.com/doc/en/myisampack.html Here's an example of how much data could be stored in a year: 1 value/minute are stored = 1440 values/day. 365 days / year. We have 100 different tables with 25 columns each. This makes 100*25*365*1440 = 1 314 000 000 values per year. A typical value could be 25,5624. How much space (in Mb) could this take up after a year do you think? A FLOAT occupies 4 or 8 bytes, depending on the precision. 131400 * 4 = 5012 Mb 131400 * 8 = 10025 Mb However, you would normally need to store something more than just the float value, otherwise it would be difficult to use the data for anything... assuming you also need an integer pointer for each value, you would need 4 extra bytes per row, and mysql also occupies 1 byte for a deletion flag, which will give you a total record length of 4+4+1=9 or 8+4+1=13. 131400 * 9 = 11278 Mb 131400 * 13 = 16290 Mb This is the size of the data, an index will require additional space.

Re: Storage issue
I'm wondering how well MySQL compress data. I'm about to design a database which will hold mainly _a lot_ of FLOAT-values, and since I do not really know how well MySQL compress data or how I could calculate this I'd really appriciate a little guidance. see chapter 6.2.6 of the mysql manual. 1 value/minute are stored = 1440 values/day. 365 days / year. We have 100 different tables with 25 columns each. This makes 100*25*365*1440 = 1 314 000 000 values per year. float: 4 byte, so you need about 5 gigs?

Re: Configure prob with FreeBSD/Linuxthreads
gcc -v Using built-in specs. Configured with: FreeBSD/i386 system compiler Thread model: posix gcc version 3.2.1 [FreeBSD] 20021119 (release) Okay. Because with native threads, enabling the second CPU (and thus locking MySQL to one thread, one process, -period-, because running another on another port isnt viable) makes the job take just over twice as long. This explains your point of view: I never tried to run MySQL on dual-processor machines. that's -unacceptable-. Even if I could justify it with Well, the second CPU is handling lots of other stuff, I still can't ignore that MySQL is still taking twice as long to do things. And I know, it's a FreeBSD problem. I'm waiting for the work done in 5.0 to be evaluated and see if it really does make MySQL work better with native threads. Absolutely. Most of FreeBSD's 4.x kernel functions are not reentrant: to solve the problem of data corruption if two or more cpu's access the same procedure, a global locking mechanism is implemented. What it means, in practice, is that if two processes calls the same kernel function, one has to wait. They are served sequentially. The mechanism worked surprising well for most applications, but not for MySQL. In MySQL, if I recall right, there's one process that forks many threads, one for every request. Threads are splitted to many cpus, but because they compete to access the same functions, some threads have to wait. This could explain why you experience halved performance. In FreeBSD 5.x all kernel functions are fully reentrant. They did a great job in many areas of the OS, often a complete rewrite to gain more performance and features. I've not tested FreeBSD 5.0 and MySQL yet, nor I plan to do it soon, because I'm happy with FreeBSD 4.x in my work. If you do, please let me (us) know. If not, this project can't wait. I'll probably have to coerce the boss into building a separate db server from the others (which wouldn't be so bad) on Linux or Solaris. Multi-cpu support in Solaris is stable, is efficient, has many years of development and it's ready to use. There's probably a reason why MySQL AB develops MySQL on Solaris first. - 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: timing
You are positive there is nothing else running while you are trying to do your reports? Have you tried keeping an eye on the processlist to see where it is getting stuck and to make sure there is nothing else going on? Where does the production server get its data from? Are their updates going on while you are running your reports? Is the production server tuned for the type of complex queries you are running? -Original Message- From: Mary Stickney [mailto:[EMAIL PROTECTED]] Sent: Thursday, January 30, 2003 12:02 PM To: Jennifer Goodie; [EMAIL PROTECTED] Subject: RE: timing no it is dedicated to the DataWarehouse Report Processor. runs one report at a time from a ReportQueue. both have a local host.

Re: Configure prob with FreeBSD/Linuxthreads
Because with native threads, enabling the second CPU (and thus locking MySQL to one thread, one process, -period-, because running another on another port isnt viable) makes the job take just over twice as long. This explains your point of view: I never tried to run MySQL on dual-processor machines. *nod*. On a single CPU, native threads gives pretty excellent performance, in both 4.7-R and 5.0-R. I haven't run a single CPU linuxthreads test yet (I think I'll go fire one off...) Absolutely. Most of FreeBSD's 4.x kernel functions are not reentrant: to solve the problem of data corruption if two or more cpu's access the same procedure, a global locking mechanism is implemented. What it means, in practice, is that if two processes calls the same kernel function, one has to wait. They are served sequentially. The mechanism worked surprising well for most applications, but not for MySQL. In MySQL, if I recall right, there's one process that forks many threads, one for every request. Threads are splitted to many cpus, but because they compete to access the same functions, some threads have to wait. This could explain why you experience halved performance. In FreeBSD 5.x all kernel functions are fully reentrant. They did a great job in many areas of the OS, often a complete rewrite to gain more performance and features. I've not tested FreeBSD 5.0 and MySQL yet, nor I plan to do it soon, because I'm happy with FreeBSD 4.x in my work. If you do, please let me (us) know. I have to say, this is the best explanation of why things work the way they do I've seen yet. Thank you. As far as 5.0, the box I'm testing on is running 5.0-R. Compiling with native threads gives near-identical performance to 4.7-R with native threads (however, there is a small performance increase in a couple steps of the job, which is nice to see. Since the hardware configuration did not change, I chalk this up to 5.0-R's rewrite affecting other parts of the equation). My assumption right now (and this is based on not having taken the time to peruse the code, so I'm likely wrong - ignore me if I am) is that MySQL says, OK, we're running on FreeBSD. Do we have more than one CPU present? Yes? OK, lock to one thread. If this is true, we are willing to disable this protective code (if feasible) and see what kind of performance/stability we get out of MySQL on 5.0-R with native threads running full bore, unrestricted. Again, this is just the ramblings of a madman (er, ok, the ramblings of a tired sysadmin :). If not, this project can't wait. I'll probably have to coerce the boss into building a separate db server from the others (which wouldn't be so bad) on Linux or Solaris. Multi-cpu support in Solaris is stable, is efficient, has many years of development and it's ready to use. There's probably a reason why MySQL AB develops MySQL on Solaris first. I wasn't aware that they developed on Solaris first, but I've had first-hand experience of Solaris multi-cpu support. It's -great-. I almost got a chance to replace an Oracle cluster with MySQL (because the support contracts are much cheaper :) in a previous life, but that life got the axe too soon.

RE: timing
The warehouse is updated once a month at night , with data from the mainframe. no records are updated or added to these databases in any other way. It is strictly a report database. They reports are ordered from a website. A record is put into a database called ReportQueue the VB app checks the queue and runs the reports one at a time and emails them out. Outlook Express is running in order to email the PDF files to the recipient. I can understand it being SOME slower , but not hours slower.
