Databases or tables? It depends on what you mean by 'handle'. Under the hood, as far as the file system goes, databases are merely directories, and tables are merely files in a database's directory. Of course, the set of database directories is kept under a single directory, whatever your 'datadir' variable is set to. All filesystems, irrespective of the OS in use, have performance problems when there are too many files (or directories) in a directory. Precisely what 'too many' is depends on the OS/filesystem in question, plus other modifiers such as how fast are your drives, how much RAM do you have, and so forth. 'Too many' is usually up in the thousands. A few hundred is usually fine. You can experience the performance of simply trying to use 'ls' on a directory; on a big directory, it will pause for a long period of time, as it gathers the list of files and sorts them. Your questions above WRT numbers of tables: creating 20 databases (total 400 tables) when you know you could create just one (total around 200 tables)? All points at numbers of files that are so small that they shouldn't be a major limit. Your first number, though: I am using a mysql server at the moment which contains 2800 different databases. Crosses that line into 'too many', for many filesystems. If your data is homogenous enough that is could be wadded up into one monster database, or broken up into an arbitrary number of smaller databases, then consider minimizing the number of databases, such that the number of tables per database is kept down in the hundreds. If your 2800 was really the number of tables in use, you could perhaps afford to scatter those tables into, say, ten databases of 280 each. But what you pick for numbers really does depend on the performance of your machines/OS/filesystem, as modified by what step's you've taken to tune your MySQL server. You're in the best position of all of us to make those tests. - could a slowdown problem causing me to have a show databases query answered in 42.50 seconds (more often being 0.02 sec) be bound to too many databases? It could be a factor, but there could be other factors, such as how heavily the MySQL server is being used at that point. Or what other activity on that box is consuming CPU or disk cycles.

Anyone out there have any experience with the book MySQL by Paul DuBois?
I'm having trouble figuring out how to save/resuse executed commands
(primarily creating tables at this point). Perhaps I could bounce a few
questions offline if you've got used this book before or think you can
assist me regardless.
It's usually as easy as 'cat sql_command.txt | mysql'.
To wit, maintain a text file of SQL commands you want executed.
I do things like:
#--
drop table if exists user;
create table user
(
user VARCHAR(254) unique NOT NULL,
user_id INT UNSIGNED not null PRIMARY KEY AUTO_INCREMENT,
password VARCHAR(32) binary NOT NULL,
name VARCHAR(254) NOT NULL,
index (user)
);
# initialize a 'default' user
insert into user (user, password, name, email)
values ('none', '--disabled--', 'No user assigned', '');
#-
This way, I can completely reset my user table at a whim, and even
annotate my data.
I go so far as to have separate tables in separate files, all named
something.sql.
Then, I can reset one table
cat user.sql | mysql test
Or all of them:
cat *.sql | mysql test
Mind you, I haven't performed the latter with foreign keys, so you
may have to take measures to assure tables are created / initialized
into the right order...
If you have a extant database, with lots of data that you're testing,
just do a mysqldump of that table (or database) into a text file,
and you can replay it as above. There are special arguments to
mysqldump to maintain the delete/create table (and database) commands,
so read those docs.
Thank you and have a great day!

This doesn't answer your question specifically, but rather, describes
a separate solution...
simple layout:
CREATE TABLE `forbidden_input` (`lfdnr` TINYINT (3) UNSIGNED DEFAULT '0'
AUTO_INCREMENT, `input` VARCHAR (255) NOT NULL, PRIMARY KEY(`lfdnr`),
UNIQUE(`input`));
Content is something like this:
1,'+'
2,'^'
3,''
4,''
5,'('

7,'~'
8,''
9,'%'
Must the forbidden inputs be in a table? Couldn't you use the
regular expression syntax instead? Something like:
SELECT `input` FROM lok_forbidden_input WHERE
'Hello World' regexp '[+^()~%]';
(This is utterly untested. Tweak as neccessary. You might need to
backquote some characacters there...)
The point being, you can build your regular expression to contain
a list of weird characters you want to match.

Will a SIGTERM shutdown while using LinuxThreads?
On another mailing list, there is a discussion about whether or not it is adequate/proper to manage the MySQL server process via a watchdog script (namely, DJB's daemontools). The point behind this watchdog script is to launch a service (such as mysqld) in the foreground, and notice if that process exits. An auxilary tool will send this managed process a SIGTERM, to request shutdown. It has been working for me under FreeBSD, and the MySQL docs imply this should work for other OSes, but someone just pointed out to me this info: http://www.mysql.com/doc/en/Linux.html When using LinuxThreads you will see a minimum of three processes running. These are in fact threads. There will be one thread for the LinuxThreads manager, one thread to handle connections, and one thread to handle alarms and signals. I myself don't use Linux, much less LinuxThreads. Can anyone advise how the theree process/threads should handle a SIGTERM in such a watchdogged environment? -- Brian 'you Bastard' Reichert[EMAIL PROTECTED] 37 Crystal Ave. #303Daytime number: (603) 434-6842 Derry NH 03038-1713 USA BSD admin/developer at large -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

I can't imagine having 40 MySQL servers running at once when I can't restrain a single one :) You can constrain a single one, very easily: # nice limits -d whatever -m whatever /usr/local/mysql/libexec/mysqld Of course, you may not want the jail methodology in general; I'm not trying to trick you into it, by any means. If you're virtual hosting, there is the implication that you have more than one customer on a single system, say, forty of them. You have at least two options: - You can let all forty clients (with all of their myriad users, sets of users, etc.) talk to a single MySQL daemon. You have the ease of no clever engineering to get the to all use this daemon, but you now have the task of accounting for their usage, and constraining them individually. - You can give each client their own separate MySQL daemon. You have the overhead of each MySQL daemon process consuming some OS resources, but now you have the freedom to almost completely manage the resources of any one of these daemons. Plus, you get to deal with the extra hassles of: - Isolating which clients want binary replication: those logs each eat up diskspace, and client's shouldn't unduly impair each other's backups. - What if one client make a request that makes MySQL spin? That'll impair everyone else's ability to process queries. - What if someone needs the ability to use DATAFILES under MySQL? Now you get to juggle who gets read/write permission to the same directories that the MySQL does... If you generalize this work above to other services, such as mail servers, web servers, etc., you'll see that you're re-solving the same kind of problem, over and over again. And when you try to worry about how much bandwidth each of these services is really consuming, one tends to migrate to virtual machines as a more complete, general solution. No matter how you cut it, you'll still have forty clients (humans, not mysql clients; each might be dozens of connections) wanting to interact with your daemon(s). Either your machine has the gnads to handle that, or it doesn't. My desktop is a dual-CPU box, with 1.5G of memory. An idle instance of MySQL looks like this: natto% ps auxwwe -p 196 USERPID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND mysql 196 0.0 1.0 11896 10728 con- S29Oct02 5023:13.08 /usr/local/mysql/libexec/mysqld --basedir=/usr/local/mysql --datadir=/usr/local/mysql/var --user=mysql --pid-file=/usr/local/mysql/var/natto.numachi.com.pid Having forty MySQL daemons, unto itself, doesn't cost the OS very much at all. But I _do_ think that for manageability, accounting, 'fairness' to your other clients, that there's a lot to said for sandboxing them as completely as possible. Using a jail gets you all they down to network traffic. If nothing else, you can learn who the 'piggy' clients are, and decide to migrate them to another box, where they have more room... Have fun. :) Justin -- Brian 'you Bastard' Reichert[EMAIL PROTECTED] 37 Crystal Ave. #303Daytime number: (603) 434-6842 Derry NH 03038-1713 USA Intel architecture: the left-hand path - 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 need some advice on tuning and restriction based on system resources. One thing you need to nail down is what the abstraction is: _how_ do you want to implement virtual hosting? For example, under FreeBSD, you can create a jail(8): a complete virtual machine tied to an IP address, and you can cram one of your (human) clients in there, with all of their services. (Before you worry about consuming all of your public IPs for such tricks, note that you can run them on private IPs, and use the kernel's ability to NAT connections in/out of the box to these virtual machines.) That technically eats more resources than other virtual hosting methods, but it most completely isolates a user from the rest of the system, if you need fine-grained control over how your machine's getting utilized, this gets you down to the nuts and bolts. The kernel itself will let you play tricks for traffic shaping, so you can constrain which of your virtual machines get traffic 'appropriately', and you can packet-filter everything to death, so that you can prevent them from running services that you don't want.

Whatever you have suggested so far hasn't worked. I thought that maybe something
is missing in my stating the problem and implementing your suggested solutions.
So here is a more expanded picture of the queries:
$sth=$dbh-prepare(INSERT INTO TABLE1 (id,var1,var2) VALUES (?,?,?));
$sth-execute(,$var1,$var2);
$sth=$dbh-prepare(SELECT \@t1id:=LAST_INSERT_ID());
$sth-execute();
$sth=$dbh-prepare(INSERT INTO TABLE1A (Aid,id,var1) VALUES (?, @t1id, $var1);
$sth-execute(,,$var1);
Doesn't this chain of events reuse the variable $sth, which essentially
closes the old statement handler? Doesn't that lose state? I'm
guessing...
Please take a note that in the last prepare statement I have also tried \@t1id
,\@t1id, LAST_INSERT_ID(). I have used these in 'execute' statement too with
question marks (?) in the prepare statement.
Any new idea please?
Try grabbing the new ID manually, before the second prepare:
my $id = $dbh-{'mysql_insertid'};
Then, manually use that as a bind variable.
Thanks,
Aamer

replication doesn't maintain logs?
I hope I've merely misread instructions. I've successfully set up replication, a master to one slave. However, even though the slave was comfigured to maintain both a 'classic' update log, as well as a binary log, none of the stuff it's replicating are reflected in the logs. Said logs are created: slave1# ls -ld * -rw-r--r-- 1 mysqld mysqld 73 Jun 18 18:53 slave1-bin.001 -rw-r--r-- 1 mysqld mysqld 31 Jun 18 18:53 slave1-bin.index -rw-r--r-- 1 mysqld mysqld 69 Jun 18 18:53 slave1.001 But, this is after I imported an entire database via replication.

Then there's the environment. Then the arguments to the server itself. (You may not that I'm not using /etc/my.cnf to configure the server; I prefer to see the arguments.) Also, the server was lauched outright as UID mysqld, so I'm not using '--user'. The user 'mysqld' has it's own group, and that's the only group it's in: bmdb2# id mysqld uid=6724(mysqld) gid=6724(mysqld) groups=6724(mysqld) Yet, somehow, an SQL command such as this: select username from user limit 5 into outfile '/var/tmp/mysqld/sample'; creates a file with the 'wheel' group: bmdb2# ls -ld /var/tmp/mysqld/sample -rw-rw-rw- 1 mysqld wheel 65 Apr 10 19:36 /var/tmp/mysqld/sample I have no idea how a non-root process can set a different group than it's own.

If you have read access to the socket, but the '10dsnlist' can't tell it there, then perhaps the test script is making a bad guess.

I'm assuming you've installed MySQL under some kind of UNIX. If so: MySQL does not have it's own 'filesystem'; it stores everything in several large files in the UNIX filesystem. MySQL (by default) keeps it's databases in /usr/local/var. This is the 'datadir' parameter to the server. You can see what yours is set to: % echo 'show variables' | mysql This will dump out a list of all of the configuration variables your server is using. Look for 'datadir'. Within that directory, there will be several sub-directories (yours will be different than mine): % ls -l /usr/local/var drwx-- 2 root wheel 512 Apr 26 2000 customers drwx-- 2 root wheel 512 Apr 26 2000 mysql drwx-- 2 root wheel 512 Apr 26 2000 test Each one of these is a database. My MySQL server has three databases, 'customer', 'mysql' and 'test'. 'mysql' is the database that the server itself uses to keep track of valid users, permissions, and the like. 'customer' is one I use for a project. That directory contains several files: % ls /usr/local/val/customer customer.ISD customer.ISM customer.frm site.ISD site.ISM site.frm My database 'customer' has two tables: 'customer' and 'site'. MySQL stores the information about any one table in three files. For example, my customer table has three files: customer.ISDthis is the data file customer.ISMthis is the index file customer.frm(I forget what this is, sorry) Where can i find local informations? I don't know what you mean; sorry. :/ now i create a database named yd for my database user.If i want to know how much space have been used,what can i do ? The 'space used' by a database is the amount of diskspace taken up by the subdirectory, including all of its files. One way is with the 'du' command: % du -k /usr/local/var/customers 20843 The '-k' flag means "count in 1024 byte blocks". Therefore, I'm using 20843 * 1024 = 21343232 bytes. (About two megabytes.)

If _all_ of the database tables are owned by the same user (ie. the user the mysqld runs as), then you could arrange that the database tables live on their own filesystem. If the database tables have to co-exist if other files owned by other users, then yes, you'd have to employ per-user quotas. As you how your OS imposed those limits, you'd have to do research. But yes, at the very least, those database table files would have to be owned by the user you're trying to constrain. If that user is different than the UID that mysqld runs under, then you'd have to assure that mysqld has read/write access to the file. As I write this, I realize I don't know if/how quotas will be imposed when mysqld's UID write to a file owned by otheruser. I suspect that mysqld's own limits will be enforced, not otheruser's. Look into: - putting the worrisome files onto their own filesystem. - resource limits (RLIMIT_FSIZE in setrlimit(2), for example.

table too big to dump?
I apologize if this has been discussed already, but I quick poke at the archives didn't reveal anything. We have a table that iamchk says is fine. We are trying to get an SQL dump of this table. But, we keep getting out-of-memory errors. I've tried several things, all to no avail, and I'm looking for advice/suggestions. Some real details: The platform: FreeBSD 3.4-RELEASE on a dual-CPU box, with 1G of physical and 2G of swap. We're running MySQL 3.22.32. This machine is idle; there are no other processes, no uses of the database, other than my client. The table: # ls -l audit_trail_271.* -rw-rw 1 root wheel 1486838307 Nov 10 05:26 audit_trail_271.ISD -rw-rw 1 root wheel84807680 Nov 10 05:26 audit_trail_271.ISM -rw-rw 1 root wheel9060 Oct 25 05:06 audit_trail_271.frm # isamchk audit_trail_271.ISM Checking ISAM file: audit_trail_271.ISM Data records: 3869676 Deleted blocks: 0 - check file-size - check delete-chain - check index reference - check data record references index: 1 - check data record references index: 2 - check record links When I try to do a mysqldump on the localhost, I get an out-of-memory error: # mysqldump -uroot -proot customer audit_trail_271 mysqldump: Out of memory (Needed 8164 bytes) mysqldump: Got error: 2008: MySQL client run out of memory When I try to a dump from over the network: # mysqldump -uroot -proot -h db_host1 customer audit_trail_271 # MySQL dump 7.1 # # Host: db_host1Database: customer # # Server version3.22.32-log # # Table structure for table 'audit_trail_271' # CREATE TABLE audit_trail_271 ( audit_trail_id int(10) unsigned DEFAULT '0' NOT NULL auto_increment, account_id int(10) unsigned DEFAULT '0' NOT NULL, user_id int(10) unsigned, bid_id int(10) unsigned, cpc int(10) unsigned, ics2_id int(10) unsigned, action varchar(20) DEFAULT '' NOT NULL, acct_amt int(11) DEFAULT '0' NOT NULL, gift_amt int(11) DEFAULT '0' NOT NULL, free_amt int(11) DEFAULT '0' NOT NULL, bill_amt int(11) DEFAULT '0' NOT NULL, decl_amt int(11) DEFAULT '0' NOT NULL, ref_base varchar(40), ref_more text, apache_log text, mtime timestamp(14), ctime datetime, PRIMARY KEY (audit_trail_id), KEY account_id (account_id) ); # # Dumping data for table 'audit_trail_271' # And there it hangs forever.

For that version of MySQL, it it useful/meaningful to activate it, if I intend to make use of a RAID array? This is impossible. RAID was introduced in 3.23.x series. Also documentation have evreything about it. 'Impossible'? Just now, I can grab: http://www.mysql.com/Downloads/MySQL-3.22/mysql-3.22.32.tar.gz And, in that tarball, on line 190 of acconfig.h: /* Use MySQL RAID */ #undef USE_RAID And there is a include/raid.h. And, Docs/mysqld_error.txt has this message defined: #define ER_NO_RAID_COMPILED 1174 "This version of MySQL is not compiled with RAID support", There is no 'RAID' attribute to the 'CREATE TABLE' syntax in the supplied docs. My question was: What is the state of that code? I _surmise_ that it's unused code, as it was not fully implemented at this point. I was uncertain if it was code that specific to the yet-to-be-introcuded RIAD attributes to a table, or if it just messed with the layout of files on disk to allow for better performance in general on RAID arrays. I merely wanted verification.

'USE_RAID' in mysql-3.22.32?
