Re: Data lost
I hope this helps. What table format are you using? When did data loss happen eg. after power loss? Yes do use the MySQL tools to repair the tables. Also you could run the bin logs back in to MySQL so all sql changes are run on the table again. The other thing to think about is locking tables can copying them to back up. This way you just have to lock db and copy back!

Rows (60 Gb on HD), the other contains nearly 200.000.000 (130 Gb on HD). Now we want to delete some rows from these tables to free diskspace. It seems that MySQL frees the harddisk-space which was used by these rows only after optimization, which lasts very long on these tables. Both tables are dynamic in terms of row-format what seems to extend the time needed for optimization. I tried to convert the smaller one to fixed-row-format, which increased the disk-space of its data-file from 30 Gb to 60 Gb. This would not be the problem, but some SQLs which are run daily on this table now run 4 times slower than with dynamic structure. So, my questions are: 1) Did i something wrong while converting to fixed row-format ? (i found no indication) 2) Is the fixed structure really faster on optimization ? 3) Can anybody confirm the slow-down on big tables when converted from dynamic to fixed ?

My question is would it be faster/more efficient to: a) Store policy wording in html format in a mysql table; or b) generate them from a perl script example user chooses plan a and plan b - hits the compare button to see policy wording compared side by side - would it be better to call it from the mysql table or a perl script? I thank you in advance.

I got a really weird behaviour from Mysql, while doing some select and update queries. I made a select, something like: SELECT Something FROM WHERE and the result was not empty. But when I tried to make an update: UPDATE..WHERE , with THE SAME WHERE clause, result was empty. I'm sure that it's not reguarding permissions, and rows were not updated yet, that is UPDATE returned: Matching rows = 0 Updated rows = 0. A MATCH() search was used in the queries.

Replication.
Hi I have two questions about replication on MySQL. One: How far behind can a SLAVE get on reading the BIN log before not being able to catch up? My SLAVE was off for 4 days and it just seams as if it can not catch up. Two: On SHOW SLAVE STATUS one of the fields in called Skip_conunter. Due to an error I ran SET SQL_SLAVE_SKIP_COUNTER=n. The number in the Skip_conunter is about the same number as I set skip to, but every time I do a SHOW SALVE STATUS it shows a different number. What dose Skip_counter mean and so why is the number changing.

RE: Mandatory server downtime?
There are two ways I use to dynamic backup. One lock table can copy it. Use some think like hotcopy. The only down side can be that if the table is very big the lock can queue two may questions. The other way it to use replication can make the backup from the slave. If it is taking up to an hour are they doing a full systems backup? Simon -Original Message- From: Clemente [mailto:[EMAIL PROTECTED]] Sent: 21 January 2003 10:44 To: [EMAIL PROTECTED] Subject: Mandatory server downtime? Hi there, My hosting company tells me that they need to take down the MySQL server every day for 30 to 60 minutes to make a backup. This is the quote: Please note that mysql is shutdown daily sometime between 3am and 9 am US eastern for 30 minutes to an hour. This is get a good backup of all mysql databases on the server during the daily backup process. Is this normal? This implies that my dynamic generated web site is down during a 2.1% to a 4.2% of the time (not counting any other server down time). I hear that normal down times for web sites are more like 1% or less. Is this really necessary? Does MySQL requires to be shutdown to generate a good backup? Any comments are welcome.

RE: Foreign keys
Use table type =Innodb for foreing keys and transacionts...etc and type =myisam for speed Simon -Original Message- From: Octavian Rasnita [mailto:[EMAIL PROTECTED]] Sent: 14 January 2003 10:20 To: MySQL Subject: Foreign keys HI all, I've read the following text in a book: ANSI SQL supports a special kind of key called a foreign key. Foreign keys help protect database integrity by enabling the database to manage things such as the deletion of rows with dependent relationships in other tables. Though MySQL supports the ANSI syntax for foreign keys, it does not actually use them to perform integrity checking in the database. This is a situation in which the introduction of a feature would cause a slowdown in performance with little real benefit. Applications themselves should generally worry about foreign key integrity. What does this mean? Does MySQL allow using foreign keys or not? Thanks.

Simon -Original Message- From: Andy Eastham [mailto:[EMAIL PROTECTED]] Sent: 13 January 2003 15:34 To: [EMAIL PROTECTED] Subject: Solaris Performance Hi, I've got a mysql application that was developed on win32 and linux that is now going to be deployed on a Sun E250 Solaris 9 box with 3 36Gb non raided SCSI disks. No problem I thought - the performance is fine on my PIII 850MHz laptop, so it will rock on an E250... Not the case - the laptop seems to be performing at twice the speed of the E250 for a simple select from a table of 55 million simple rows (just 3 floating point numbers per row - the .MYD file is 700Mb and the .MYI index file is 2.7Gb). It takes 1.2 seconds on the laptop and 2.5 seconds on the sun. This is a big problem, as I have to do three of these queries plus processing and return in under 10 seconds. The laptop takes 6 seconds, the Sun takes 12. I've got a Linux PIII 933MHz Dell Server which at least half as much again faster than the laptop. I've increased the key cache to 250Mb on the Sun (it's at the default on the laptop), but no radical difference was apparent. The Sun install is pretty much out of the box, apart from the file system organisation. MySQL has its own disk. I'm running the 32 bit variants of MySQL. Would the 64 bit be any different (Solaris 9 is installed with 32 bit and 64 bit support)? Has anyone got any similar experience? Can any one recommend trying anything?

Hi, I suppose this may be slightly off topic and not really relevant to a mysql mailing list, sorry... but... I've spent the last month getting up to speed with MySQL with much help from you guys and Mr DuBois' book. I've done this because an existing client of mine has a system which works with a database engine we developed in house for cheap and cheerful little database applications but their requirements have increased to a point where our little engine is running at max throttle. I proposed that I convert their setup to work with MySQL and said that I would not charge for my time spent learning how to use MySQL. My question is: when developing _any_ software it's almost always a bit of a learning process. I'm always referring to reference manuals etc. etc. whenever I'm developing, even in the languages I'm most familiar with. So where do I draw the line? How can I identify a reasonable point at which it's fair to start logging some hours down to my client?

Subject: MySQL CPU usage skyrocketing
Hi,
I am running MySQL 3.23.41 on a FreeBSD 4.4, and I experience very high
loads of the machine, without any apparent reason. We have a new project
using this MySQL engine, with lots of inserts/deletes. But it happens that
in the mornings, when nobody makes any kind of access to the database, we
still have a MySQL daemon eating up 99% of CPU. If I log in as 'root' to
the mysql server and make a 'show processlist', the only process in the
'query' command is mine ('show processlist'), all the others are in sleep
mode (with NULL info). Is there any periodic maintanance/optimization work
that the mysql server is doing? If so, why does it take so long? Can I
schedule it sometimes during the night (and if so, how?)
Thanks,
bogdan

OK two thinks to lookat
1. Use GRANTS as you will not have so much truble with them
2. Use mysqlaccess this will tell you if you have got the privileges
right..
If a user can select in 'user' table then he can do so on all databases.
(what ever is set in 'db')
If a user can select in 'db' table then he can do so on that database (what
ever is set in 'table_priv')

Subject: Privileges - Does Anybody knows how to answer to me?
Hi, I read the book, but there is not explain about it.
I would like to know when I give privileges to the user, in the table
level, and after I give privileges in the database level. Do I replace the
privileges?
There are two tables ('db' and 'tables_priv') in mysql database.
I gave privileges, for example, to the table 'tables_priv', I give only
'select' privilege to the table Tb01.
But I give other privileges, now to the table 'db'. I gave 'insert',
'delete' and 'update' privileges to the database 'Test'.
Now the user has privileges to:
- 'select' the table 'Tb01'
- ''insert', 'delete' and 'update' the database 'Test'. Right
---
What can he do?
Can he insert or delte on the table tb01?
Can he select data in all the tables of the database 'Test'?

RE: Another 'Too many connections' question...
Too many connections Is the message you get when all are used up. The limit is about 1000 (Linux) but can be set higher. With MySQL you can set a limit for each user. So I would set this to say 100 for each user and 1000 in total. What courses this is pconnects or threads that will not drop. If you use pconnects and don't re use them client side these can had around till they are dropped (8 hours standard). The other thing that can happen is when a table is locked by backups or a log question other connections can get backed up.

RE: check, analyze and optimize table
Would you not be better of just runing myisamchk from crontab? Simon ./myisamchk Ver 1.52 for unknown-freebsdelf4.1 at i386 By Monty, for your professional use This software comes with NO WARRANTY: see the PUBLIC for details. Description, check and repair of ISAM tables. Used without options all tables on the command will be checked for errors Usage: ./myisamchk [OPTIONS] tables[.MYI] Global options: -#, --debug=... Output debug log. Often this is 'd:t:o,filename` -?, --help Display this help and exit. -O, --set-variable var=option Change the value of a variable. -s, --silentOnly print errors. One can use two -s to make myisamchk very silent -v, --verbose Print more information. This can be used with --describe and --check. Use many -v for more verbosity! -V, --version Print version and exit. -w, --wait Wait if table is locked. Check options (check is the default action for myisamchk): -c, --check Check table for errors -e, --extend-check Check the table VERY throughly. Only use this in extreme cases as myisamchk should normally be able to find out if the table is ok even without this switch -F, --fast Check only tables that hasn't been closed properly -C, --check-only-changed Check only tables that has changed since last check -f, --force Restart with -r if there are any errors in the table. States will be updated as with --update-state -i, --information Print statistics information about table that is checked -m, --medium-check Faster than extended-check, but only finds 99.99% of all errors. Should be good enough for most cases -U --update-state Mark tables as crashed if you find any errors -T, --read-only Don't mark table as checked Repair options (When using -r or -o) -B, --backupMake a backup of the .MYD file as 'filename-time.BAK' --correct-checksum Correct checksum information for table. -D, --data-file-length=# Max length of data file (when recreating data file when it's full) -e, --extend-check Try to recover every possible row from the data file Normally this will also find a lot of garbage rows; Don't use this option if you are not totally desperate. -f, --force Overwrite old temporary files. -k, --keys-used=# Tell MyISAM to update only some specific keys. # is a bit mask of which keys to use. This can be used to get faster inserts! -r, --recover Can fix almost anything except unique keys that aren't unique. -n, --sort-recover Force recovering with sorting even if the temporary file would be very big. -o, --safe-recover Uses old recovery method; Slower than '-r' but can handle a couple of cases where '-r' reports that it can't fix the data file. --character-sets-dir=... Directory where character sets are --set-character-set=name Change the character set used by the index -t, --tmpdir=path Path for temporary files -q, --quick Faster repair by not modifying the data file. One can give a second '-q' to force myisamchk to modify the original datafile in case of duplicate keys -u, --unpackUnpack file packed with myisampack. Other actions: -a, --analyze Analyze distribution of keys. Will make some joins in MySQL faster. You can check the calculated distribution by using '--describe --verbose table_name'. -d, --description Prints some information about table. -A, --set-auto-increment[=value] Force auto_increment to start at this or higher value If no value is given, then sets the next auto_increment value to the highest used value for the auto key + 1. -S, --sort-indexSort index blocks. This speeds up 'read-next' in applications -R, --sort-records=# Sort records according to an index. This makes your data much more localized and may speed up things (It may be VERY slow to do a sort the first time!) Default options are read from the following files in the given order: /etc/my.cnf /usr/local/mysql/var/my.cnf ~/.my.cnf The following groups are read: myisamchk The following options may be given as the first argument: --print-defaultsPrint the program argument list and exit --no-defaults Don't read default options from any options file --defaults-file=# Only read default options from the given file # --defaults-extra-file=# Read this file after the global files are read -Original Message- From: Peter Romianowski [mailto:[EMAIL PROTECTED]] Sent: 09 April 2002 12:08 To: [EMAIL

RE: MYSQL DATABASE BACKUP
Yes and no If you are taking info from a live database you would have it in a steady state to copy it. This means locking the tables. But once you have a copy of the table all you would need to do is update the changes from the logs. Using replication for this I is the most simple way but would mean a second copy of MySQL but you would only need a low spec system.. I hope this helps...
